Correlates of emotional violence against children in Rwanda: Findings from a cross-sectional national survey.

National data on children affected by violence are critical in preventing violence against children. Rwanda conducted its first cross-sectional national survey on violence against children in 2015. This study used data from the Rwanda Survey to describe the profile of children affected by emotional violence (EV) and to assess factors associated with it in Rwanda. A sample of 1,110 children (618 boys and 492 girls) aged 13-17 from the Rwanda Survey was analysed. Weighted descriptive statistics were applied to describe the prevalence of EV and the profile of children affected by it. In addition, factors associated with EV were investigated using logistic regression. Male children were more likely to experience EV than female children. Nine percent (8.87%, 95% CI [6.95-11.25]) of male children versus five percent (5.17%, 95% CI [3.79-7.03]) of female children reported having experienced EV in their lifetime. Seven percent (6.77%, 95% CI [5.15-8.84]) of male children versus four percent of female children (3.97%, 95% CI [2.83-5.54]) reported having experienced EV in the last twelve months before the survey. Fathers and mothers were the top two perpetrators of EV against children. Seventeen percent of male children (17.09%, 95% CI [11.06-25.47]) and 12 percent of female children (11.89%, 95% CI [6.97,19.55]) reported EV by their fathers. Mothers were responsible for nineteen percent (19.25%, 95% CI [12.94-27.65]) of EV reported by male children and eleven percent (10.78%, 95% CI [5.77-19.25]) of EV reported by female children. Female children (OR = 0.48, 95% CI [0.31-0.76]) and children with some trust in people from their communities (OR = 0.47, 95% CI [0.23-0.93]) were less likely to report EV. Factors associated with risk for EV were not attending school (OR = 1.80, 95% CI [1.10-2.92]), living with father only (OR = 2.96, 95% CI [1.21-7.85]), not feeling close to biological parents (OR = 7.18, 95% CI [2.12-24.37]), living in a larger household (OR = 1.81, 95% CI [1.03-3.19]), not having a friend (OR = 2.08, 95% CI [1.02-4.11]), and not feeling safe in the community (OR = 2.56, 95% CI [1.03-6.38]). EV against children was pervasive in Rwanda, with parents topping the list of its perpetrators. Children from unsupportive socioeconomic family environments, i.e., children without a close relationship with biological parents, children not attending school, children living with their fathers only, children from larger households of five people and more, children without a friend, and children who reported not feeling safe in their communities, were identified as groups of children vulnerable to emotional violence in Rwanda. A family-centred approach, focusing on positive parenting and protecting vulnerable children, is needed to reduce emotional violence against children and the risk factors associated with it in Rwanda.

Iodine status and its association with prevalence of thyroid diseases in adults from Jiangxi Province, China.

Iodine is an essential element for the biosynthesis of thyroid-stimulating hormone (TSH). Both excessive and deficient iodine are major risk factors for thyroid diseases, including thyroid dysfunction, thyroid nodules, and thyroid autoimmunity (TAI). This study aimed to elucidate the relationship between iodine status and the prevalence of thyroid diseases through a national cross-sectional epidemiological survey in Jiangxi province (China). This population-based, cross-sectional study enrolled 2636 Chinese local inhabitants who aged over 18 years old from April to August in 2015. Physical examination was performed and biochemical indices, urinary iodine concentration (UIC), and TSH level were measured. The Chi-square test, nonparametric test, and 4 multivariate logistic regression models adjusted for risk factors were applied to analysis. Spearman correlation coefficients were calculated to investigate the relationship between iodine intake level and the prevalence of thyroid diseases. The median UIC was 176.4 μg/L, and a significant difference was found in median UIC between men (182.45 μg/L) and women (169.25 μg/L) (P = 0.03). Among these study subjects, 14.4%, 44.5%, 26.1%, and 15.0% had deficient, adequate, more than adequate, and excessive iodine concentrations, respectively. The prevalence rates of hyperthyroidism, subclinical hyperthyroidism, hypothyroidism, subclinical hypothyroidism, thyroid nodules, and TAI were 0.91%, 0.57%, 0.34% and 7.89%, 9.45%, and 12.7%, respectively. Significant differences were found in iodine status, waist circumstance, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), TSH, thyroid nodules, and TAI between men and women (P < 0.05). Compared with those with adequate UIC, subjects with excessive UIC had higher prevalence rates of thyroid dysfunction (odds ratio (OR) = 1.74, 95% confidence interval (CI): 1.40-2.54) and thyroid nodules (OR = 3.33, 95%CI 1.32-8.42). In addition, subjects with deficient and excessive UIC were at the higher risk of TAI compared with those with adequate UIC (OR = 1.68, 95%CI: 1.19-2.60; OR = 1.52, 95%CI: 1.04-2.96, respectively). UIC was positively correlated with the prevalence rates of thyroid nodules (r = -0.44, P < 0.01) and TAI (r = -0.055, P < 0.01). On the contrary, UIC was negatively correlated with the risk of thyroid dysfunction (r = -0.24, P > 0.05). Adult inhabitants from Jiangxi province in the TIDE study were in the adequate iodine status. Excessive iodine status was noted as a risk factor for thyroid dysfunction and thyroid nodules. In addition, both iodine deficiency and excessive iodine were risk factors for TAI.

Reasonable access: important characteristics and perceived quality of legal and illegal sources of cannabis for medical purposes in Canada

BackgroundThroughout the past two decades of legal medical cannabis in Canada, individuals have experienced challenges related to accessing legal sources of cannabis for medical purposes. The objective of our study was to examine the sources of cannabis accessed by individuals authorized to use medical cannabis and to identify possible reasons for their use of illegal sources.MethodsIndividuals who participated in the Cannabis Access Regulations Study (CANARY), a national cross-sectional survey launched in 2014, and indicated they were currently authorized to use cannabis for medical purposes in Canada were included in this study. We assessed differences between participants accessing cannabis from only legal sources versus from illegal sources in relation to sociodemographic characteristics, health-related factors, and characteristics of medical cannabis they considered important. A secondary analysis assessed differences in satisfaction with various dimensions of cannabis products and services provided by legal versus illegal sources.ResultsHalf of the 237 study participants accessed cannabis from illegal sources. Individuals accessing cannabis from illegal sources were significantly more likely to value pesticide-free products, access to a variety of strains, ability to select strain and dosage, ability to observe and smell cannabis, availability in a dispensary, and availability in small quantities than did individuals accessing cannabis from only legal sources (all p < 0.05). Additionally, participants gave significantly higher satisfaction scores to illegal sources than to legal sources on service-related dimensions of cannabis access (all p < 0.05).ConclusionOur findings contribute to an understanding of reasonable access to medical cannabis from a patient perspective and how to assess whether it has been achieved. Characteristics of cannabis products and services valued by patients and appropriate to their needs should be incorporated into legal medical cannabis programs to promote the use of legal medical sources. While pertaining specifically to medical use of cannabis in Canada, the findings of this study may also be instructive for understanding the use of illegal cannabis sources for non-medical purposes in Canada and provide insight for other jurisdictions implementing cannabis regulations for both medical and non-medical purposes.

Predictors of self-reported research productivity amongst medical students in the United Kingdom: a national cross-sectional survey

BackgroundThe number of academic clinicians in the UK is declining and there are demographic inequalities in the clinical-academic workforce. Increased research productivity by medical students is believed to reduce future attrition in the clinical-academic workforce. Thus, this study investigated the association between student demographics and research productivity amongst UK medical students.MethodsThis is a national multicentre cross-sectional study of UK medical students in the 2020/21 academic year. We appointed one student representative per medical school, and they disseminated a 42-item online questionnaire over nine weeks, through departmental emails and social media advertisements. The outcome measures were: (i) publications (yes/no) (ii) number of publications (iii) number of first-authored publications (iv) abstract presentation (yes/no). We utilised multiple logistic and zero-inflated Poisson regression analyses to test for associations between the outcome measures and predictor variables at a 5% significance level.ResultsThere are 41 medical schools in the UK. We received 1573 responses from 36 UK medical schools. We failed to recruit student representatives from three newly formed medical schools, whilst two medical schools prohibited us from sending the survey to their students. Women had lower odds of having a publication (OR: 0.53, 95% CI: 0.33–0.85) and on average had fewer first-author publications than men (IRR: 0.57, 95% CI: 0.37–0.89). Compared to white students, mixed-ethnicity students had greater odds of having a publication (OR: 3.06, 95% CI: 1.67–5.59), an abstract presentation (OR: 2.12, 95% CI: 1.37–3.26), and on average had a greater number of publications (IRR: 1.87, 95% CI: 1.02–3.43). On average, students who attended independent UK secondary schools had a higher rate of first-author publications compared to those that attended state secondary schools (IRR: 1.97, 95% CI: 1.23–3.15).ConclusionOur data suggest that there are gender, ethnic and socioeconomic inequalities in research productivity among UK medical students. To tackle this, and potentially improve diversity in clinical academia, we recommend that medical schools should facilitate targeted high quality research mentorship, funding and training, especially for under-represented-in-medicine students.

Australian nursing students’ perception, knowledge, and attitude towards oral healthcare of older people and associated factors: a national cross-sectional survey

BackgroundThe oral health of many older Australians is poor and associated with many systemic health problems. However, nurses often have a limited understanding of the importance of oral healthcare for older people. This study aimed to investigate Australian nursing students’ perception, knowledge, and attitude toward providing oral healthcare for older people and associated factors.MethodsA cross-sectional study was conducted among final year nursing students studying at accredited nursing programs using an online self-reported 49-item survey. The data were analysed using univariate and bivariate analysis (t-test, ANOVA, Spearman’s correlation test).ResultsA total of 416 final-year nursing students from 16 accredited programs in Australia completed the survey. Mean scores showed that more than half of the participants felt they lacked confidence (55%, n = 229) and had limited knowledge about oral healthcare for older people (73%, n = 304); however, their attitude towards providing such care was favourable (89%, n = 369). A positive correlation was found between students’ confidence in delivering oral healthcare to older people and their perceived knowledge (r = 0.13, p < 0.01). Results revealed a statistically significant positive association between students’ experience in providing oral healthcare to older people and students’ perception (t = 4.52, p < 0.001), knowledge (t = 2.87, p < 0.01), and attitude (t = 2.65, p < 0.01) mean scores in such care. Nearly 60% (n = 242) of participants received education/training in oral healthcare for older people at university, but this was often for less than one hour. Around 56% (n = 233) believed that the current nursing curriculum did not prepare them to provide effective oral healthcare to older people.ConclusionFindings suggested a need for nursing curricula to be revised to include oral health education and clinical experience. Knowledge of evidence-based oral healthcare by nursing students may improve the quality of oral healthcare for older people.

Nurses’ perceptions of the skills, knowledge and attributes required to optimise scope of practice and improve access to care for people experiencing homelessness in Australia: A cross-sectional study

BackgroundPeople experiencing homelessness are less likely to access healthcare, particularly primary and preventive care. Nurses are well placed to improve access to healthcare for this vulnerable population.AimTo explore nurses’ perceptions of the skills, knowledge and attributes required to optimise scope of practice and improve access to healthcare for people experiencing homelessness, to underpin an education framework.DesignA cross-sectional national survey of nurses in Australia.MethodsPart of a larger study, a 222-item electronic survey was disseminated via social media and nursing colleges and associations. Participants rated the level of priority of specific skills knowledge and attributes to optimise nurses’ scope of practice and improve access to care for people experiencing homelessness. Quantitative data were analysed descriptively and qualitative data thematically.FindingsThe final analysis comprised n = 67 surveys. Participants were registered nurses (n = 54), nurse practitioners (n = 12) and one enrolled nurse. Items rated as highest priority and used in practice to optimise access to care were interpersonal attributes (n = 66.5, 99%), diagnosing presenting complaints (n = 64, 95%) and interpreting diagnostic test results (n = 63, 93%). Organisationally, support from colleagues (n = 58, 87%), managers (n = 57, 85%) and clear clinical guidelines (n = 46, 69%) are reportedly important. Most participants stated willingness to undertake further education in the care of people experiencing homelessness (93%, n = 62).ConclusionIn developing a nursing education framework to optimise nurses’ scope of practice and improve access to care for people experiencing homelessness, the findings suggest that interpersonal skills, diagnosis and treatment are priority topics.

Physiotherapists’ experience with online group exercise classes: A nationwide survey

INTRODUCTION: The Covid-19 pandemic provided a research opportunity to explore online group exercise programmes in larger numbers while restrictions on group gatherings were in place. An online survey was conducted with Irish Physiotherapists to ascertain their views on online group exercise programmes and the methods they employed to conduct their online classes in order to guide Physiotherapists with future care delivery. METHODS: A mixed-methods design was employed using a cross-sectional national online survey of Physiotherapists in Ireland. The survey collected both qualitative and quantitative data. Descriptive statistics were used to summarise the ordinal and continuous data and free-text responses were analysed using conventional content analysis. RESULTS: In total, 81 Physiotherapists completed the surveys. The majority of Physiotherapists (62%) feel a blended or hybrid model is the best option for the future. Convenience and decreased travel were cited as the main advantages of online classes. Physiotherapists cited in-person classes as being of higher teaching quality with improved safety and social interaction. Physiotherapists indicated that very little staff or technological resources were needed for their online classes and serious adverse events during the classes were extremely infrequent. CONCLUSION: Online group exercise programmes were well received by Physiotherapists, although the majority of those questioned believe a mixture of both online and in person exercise classes should be offered going forward.

Endodontic infection control practices among Pakistani general dental practitioners: A national cross-sectional questionnaire survey

ObjectiveThis study was aimed at evaluating the self-reported endodontic infection control practices of general dental practitioners in Pakistan. MethodsAn e-questionnaire was sent to 619 general dental practitioners in several WhatsApp groups. Sixteen questions associated with various infection control measures recommended by the ESE were asked, including the use of various isolation methods/rubber dams, the selection of canal irrigants and anti-bacterial solutions, and practices regarding hand hygiene and use of examination gloves. The e-questionnaire also included questions associated with demographics. Data analysis was conducted in SPSS-24. Descriptive statistics were documented as percentages and frequencies. ResultsOf 619 GDPs, 350 responded (56.5% response rate), of whom 43.7% worked in private dental practices. The majority were women (64%), had graduated after 2010 (81.1%), and were 24–34 years of age (78.9%). A total of 72.3% of GDPs used cotton rolls, and 17.4% routinely used rubber dams for endodontic isolation; 89% did not disinfect the operative field; 80% reported using different concentrations of NaOCl during root canal instrumentation; and 0.9% reported not using any irrigant during endodontic procedures. A total of 61.7% reported always using intra-canal medication during multi visit endodontic treatment, among whom 82.5% reported using Ca(OH)2. Finally, 100% of respondents reported using gloves during endodontic treatment. ConclusionThe results indicated that the GDPs tended to follow some of the endodontics quality standards recommended by the ESE, but the overall implementation of all guidelines requires improvement.

Determinants of COVID-19 vaccine uptake among Nigerians: evidence from a cross-sectional national survey

BackgroundCOVID-19 ranks as one of the largest public health threats in recent times. It is associated with huge health, economic and social consequences. Although vaccination is an effective control measure, COVID-19 vaccine uptake has been suboptimal in many low/middle income countries. Hence this study assessed the factors influencing COVID-19 vaccine uptake among Nigerian households.Data and methodsThis study analyzed secondary data from the COVID-19 High-Frequency Phone Survey of Households that was collected by the National Bureau of Statistics between November 2021 and January 2022. Relevant data were analyzed using descriptive statistical tools and the Multivariate Regression model.ResultsOut of 2370 respondents, only 32.8% of the respondents were vaccinated against COVID-19. Respondents living in urban areas (34.4%) had a higher level of COVID-19 vaccine uptake relative to those living in rural Nigeria (30.9%). Results from the Multivariate Regression model revealed that adults aged ≥ 60 years (OR 2.20; p = 0.012), respondents with primary (OR 1.72; p = 0.032), secondary (OR 1.77; p = 0.025) and tertiary education (OR 3.03; p < 0.001), respondents with access to health insurance (OR 1.68; p = 0.004), those who obtained vaccine information from health workers (OR 3.92; p < 0.001), the government (OR 3.22; p < 0.001), and the mass media (OR 1.75; p = 0.003) were more likely to be vaccinated. Also, respondents living in North Central (OR 2.02; p < 0.001), North East (OR 1.48; p = 0.039), South West (OR 2.63; p < 0.001), and South South (OR 1.49; p = 0.031) regions had higher odds of being vaccinated.ConclusionsThe study recommends increased media campaigns and advocacy for COVID-19 vaccination in the South East and North West regions. Persons with no formal education and younger persons aged 18–29 years should be targeted with COVID-19 vaccine-related information given that they were less likely to be vaccinated. Dissemination of relevant information through government sources, mass media and health workers is encouraged so as to positively influence decisions to receive COVID-19 vaccines among citizens.

The prevalence of breastfeeding aversion response in Australia: A national cross-sectional survey.

Some women who breastfeed will experience complex ongoing difficulties, such as breastfeeding aversion response (BAR). This recently named breastfeeding challenge is defined as feelings of aversion while breastfeeding for the entire time that the child is latched. This study provides the first prevalence data for the experience of BAR in Australian breastfeeding women. A national online survey investigated the breastfeeding experience of Australian women including data on (1) participant demographics, (2) breastfeeding experience with up to four children, (3) breastfeeding challenges and prevalence of BAR, and (4) the value of available breastfeeding support. This study found that of the Australian breastfeeding women who participated (n = 5511), just over one in five self-identified as having experienced a BAR (n = 1227, 22.6%). Most reported experiencing some breastfeeding challenges, with only 4.5% (n = 247) having had no breastfeeding complications. Importantly, despite these difficulties, 86.9% of the total women in this study rated their overall breastfeeding experience as good (n = 2052, 37.6%), or very good (n = 2690, 49.3%), and 82.5% of those who experience BAR as good (n = 471, 38.7%) or very good (n = 533, 43.8%). BAR reporting was decreased in higher education and income groups. Women who are breastfeeding for the first time are more likely to encounter difficulties with breastfeeding such as BAR. Complications with breastfeeding are pervasive, but women who can overcome breastfeeding issues often report a positive overall breastfeeding experience.

Analysis of the status of social frailty in Chinese older adults with cardiovascular and cerebrovascular diseases: a national cross-sectional study.

Social frailty is one type of frailty. Physical frailty with cardiovascular and cerebrovascular diseases (CCVD) have been studied a lot, but less research on social frailty. To study the prevalence, related risk factors and regional differences of social frailty with CCVD in Chinese older adults. SSAPUR was a national cross-sectional survey. Participants aged 60 years or older were recruited in August 2015. Demographic data and information regarding family, health and medical conditions, living environment conditions, social participation, spiritual and cultural life, and health condition were obtained. Social frailty was assessed in five areas (HALFE Social Frailty Index) including inability to help others, limited social participation, loneliness, financial difficulty, and living alone. The prevalence of CCVD with social frailty, related risk factors and regional differences in CCVD with social frailty were studied. A total of 222,179 participants were enrolled. 28.4% of them had CCVD history. The prevalence of social frailty in the CCVD group was 16.03%. In CCVD participants, compared with the group without social frailty, there were significant differences in gender, age, urban-rural distribution, ethnicity, marital status, and education levels in the social frailty group. Significant differences were also found in physical exercise participation, health status, cataract, hypertension, diabetes mellitus, hospitalization within 1 year, self-assessed health status, crutch or wheelchair usage, urinary and fecal incontinence, need for care from others, fall history, housing satisfaction, and self-assessed happiness in the social frailty group. Women with CCVD had a higher prevalence of social frailty than men. By age in CCVD with social frailty, the highest prevalence was found in participants 75-79 years old. The prevalence of CCVD was significant difference between social frailty in urban and rural group. The prevalence of social frailty with CCVD was significantly different in different regions. The highest prevalence was 20.4% in southwest area, and the lowest prevalence was 12.5% in northeast with area. The prevalence of social frailty among the CCVD older adults is high. Factors such as gender, age, region, urban-rural residence, and the state of the disease may be associated with social frailty.

An examination of the emerging field of community paramedicine: a national cross-sectional survey of community paramedics

BackgroundCommunity Paramedicine is an evolving community-based model that expands paramedic roles from emergency and transport care to a focus on non-emergent and preventive health services tailored to local community needs. Though community paramedicine is a growing field and acceptance is gradually increasing, there is limited information on community paramedics (CPs) perceptions of their expanded roles. The study’s aim is to assess CPs’ perceptions about their training, roles, role clarity, role readiness, role satisfaction, professional identity, interprofessional collaboration, and the future of the community paramedicine care model.MethodsUsing the National Association of Emergency Medical Technicians-mobile integrated health (NAEMT-MIH) listserv, a cross-sectional survey was conducted in July/August 2020 using a 43-item web-based questionnaire. Thirty-nine questions evaluated CPs’ training, roles, role clarity, role readiness, role satisfaction, professional identity, interprofessional collaboration, and program/work characteristics. Four open-ended questions examined perceptions of the future of community paramedicine care models and challenges/opportunities encountered during the COVID-19 pandemic. Data was analyzed using Spearman’s correlation, Wilcoxon Mann–Whitney U, and Kruskal–Wallis tests. Open-ended questions were analyzed using qualitative content analyses.ResultsResponses from fifty-seven CPs were analyzed. Most (80%) completed didactic and/or clinical training. Nearly all respondents (96.5%) performed health assessments; only 38.6% administered vaccines. Overall, participants were neutral about their role readiness with a mean score of 3.3/5.0. The mean role clarity was 15.5 (range 4–29; higher scores = higher clarity), professional identity was 46.8 (range 30–55; higher scores = higher identity), role satisfaction was 4.4/5 with 5 = very satisfied, and interprofessional collaboration was 9.5/10 (10 = very important). Role clarity training (rho = 0.4, p = 0.0013) and higher interprofessional collaboration (rho = 0.4, p = 0.0015) were found to be significantly associated with the enhancement of professional identity. Respondents who completed training showed higher role satisfaction compared to those who did not (p = 0.0114). COVID-19 challenges included keeping up with emerging policies/procedures, CPs’ well-being, and inadequate funding to meet service needs; opportunities identified included service delivery expansion and CPs meeting community needs in a flexible manner. Respondents reported that sustainable payment models, expanding services, and geographic reach were important to the future of community paramedicine.ConclusionsInterprofessional collaboration is important to fulfill CPs roles. Role clarity and readiness could be improved, which aligns with the emerging nature of community paramedicine. The future of the community paramedicine care model is dependent on funding and expanding reach of services.

Usual nutrient intakes and diet quality among United States older adults participating in the Supplemental Nutrition Assistance Program compared with income-eligible nonparticipants

BackgroundThe proportion of older adults with food insecurity at 8% has increased faster than that of the general United States population from 2001 to 2017. Many low-income food-insecure older adults rely on food-assistance programs, such as the Supplemental Nutrition Assistance Program (SNAP), for meeting energy and nutrient needs, whereas others are eligible but do not participate. Neither updated nutrient intake estimates nor potential differences in meeting the Dietary Reference Intakes from foods alone and with dietary supplements (DS) among low-income older adults using or eligible for SNAP are known. ObjectivesThis study assessed and compared national estimates of usual nutrient adequacy and dietary quality of United States older adults using SNAP and income-eligible nonparticipants. MethodsUsual dietary intake was estimated among older adults (≥60 y; n = 2582) in the 2007–2016 NHANES cross-sectional national survey. Data on food-assistance participation and eligibility (poverty-income-ratio ≤130%), DS use, and ≥24-h dietary recalls were used. The NCI method (Markov Chain Monte Carlo approach) was applied to estimate mean usual nutrient intakes, proportion of inadequate nutrient intake, and dietary quality using the 2015 Healthy Eating Index. ResultsNeither usual nutrient intake from dietary and total sources nor dietary quality differed between older adult SNAP participants and eligible nonparticipants. Low dietary quality and high percentage of inadequate intake for several nutrients were apparent among both groups, especially from food sources alone, including vitamins A (56%), C (55%), D (97%), E (99%), calcium (73%), and magnesium (74%), but rates were attenuated when DS were also considered (i.e., 36% reduced risk for vitamin D inadequacy). ConclusionsDiet quality and usual nutrient intake among older adult SNAP participants and eligible nonparticipants were poor, but DS lowered the risk of nutrient inadequacy. Future policies and programs should focus on improving the intake of vitamins A, C, D, E, calcium, and magnesium and dietary quality for all older adults.

The effects of green space and physical activity on muscle strength: a national cross-sectional survey with 128,759 Chinese adults.

Muscle strength is closely related to chronic noncommunicable diseases; specifically, a decline in handgrip strength (HS) is predominant globally. Exposure to green space-built environment components used for health intervention-reportedly decreases the risk of certain diseases and all-cause mortality. However, evidence in this area is limited. We aimed to explore the association between green space exposure and muscle strength and ascertain the combined effect of physical activity and green space exposure on muscle strength. Data from 128,759 participants (aged 20-79 years) were obtained using a complex stratified multistage probability cluster sampling design. The green space was assessed as normalized difference vegetation index (NDVI) data for a 500-m buffer zone based on the geolocation information of sampling sites. We used a questionnaire to investigate transportation, occupation, physical activity, leisure-time exercise behaviors, and sedentary time within a usual week of the preceding year. The outcome was low relative HS, defined as HS-to-body weight ratio, and the percentage of men and women with relative HS in the lower third. We defined adequate physical activity as 150 min of moderate-intensity or 75 min of vigorous physical activity per week and calculated the weighted proportion of participants with insufficient physical activity. Categorical variables of NDVI and physical activity were used as exposure variables and their interrelationship was evaluated in a generalized linear mixed model (GLMM) to estimate the odds ratios (ORs) and 95% confidence intervals (95% CI). We measured interaction on an additive or multiplicative scale using a GLMM to test the interaction between green space exposure and physical activity. All analyses were performed for the total sample and subgroups (urban and rural). The high NDVI group had a lower risk of low relative HS than the low NDVI group (OR [95% CI]: 0.92 [0.88-0.95]). The sufficient physical activity group had a lower risk of low relative HS than the insufficient physical activity group (OR [95% CI]: 0.85 [0.81-0.88]). There was an interactive effect on the additive scale (relative excess risk owing to interaction: 0.29, 95% CI 0.22-0.36, p < 0.001) between green space exposure and physical activity. High NDVI and adequate physical activity were protective factors against low relative HS in Chinese adults. Increasing green space exposure and physical activity together may have a greater potentiating effect on muscle strength improvement than these two protective factors individually. Green spaces should be incorporated into city design or built environments.

Development of a Prediction Model for Healthy Life Years Without Activity Limitation: National Cross-sectional Study.

In some countries, including Japan-the leading country in terms of longevity, life expectancy has been increasing; meanwhile, healthy life years have not kept pace, necessitating an effective health policy to narrow the gap. The aim of this study is to develop a prediction model for healthy life years without activity limitations and deploy the model in a health policy to prolong healthy life years. The Comprehensive Survey of Living Conditions, a cross-sectional national survey of Japan, was conducted by the Japanese Ministry of Health, Labour and Welfare in 2013, 2016, and 2019. The data from 1,537,773 responders were used for modelling using machine learning. All participants were randomly split into training (n=1,383,995, 90%,) and test (n=153,778, 10%) subsets. Extreme gradient boosting classifier was implemented. Activity limitations were set as the target. Age, sex, and 40 types of diseases or injuries were included as features. Healthy life years without activity limitations were calculated by incorporating the predicted prevalence rate of activity limitations in a life table. For the wide utility of the model in individuals, we developed an application tool for the model. In the groups without (n=1,329,901) and with (n=207,872) activity limitations, the median age was 47 (IQR 30-64) and 69 (IQR 54-80) years, respectively (P<.001); female sex comprised 51.3% (n=681,794) in the group without activity limitations and 56.9% (n=118,339) in the group with activity limitations (P<.001). A total of 42 features were included in the feature set. Age had the highest impact on model accuracy, followed by depression or other mental diseases; back pain; bone fracture; other neurological disorders, pain, or paralysis; stroke, cerebral hemorrhage, or infarction; arthritis; Parkinson disease; dementia; and other injuries or burns. The model exhibited high performance with an area under the receiver operating characteristic curve of 0.846 (95% CI 0.842-0.849) with exact calibration for the average probability and fraction of positives. The prediction results were consistent with the observed values of healthy life years for both sexes in each year (range of difference between predictive and observed values: -0.89 to 0.16 in male and 0.61 to 1.23 in female respondents). We applied the prediction model to a regional health policy to prolong healthy life years by adjusting the representative predictors to a target prevalence rate. Additionally, we presented the health condition without activity limitations index, followed by the application development for individual health promotion. The prediction model will enable national or regional governments to establish an effective health promotion policy for risk prevention at the population and individual levels to prolong healthy life years. Further investigation is needed to validate the model's adaptability to various ethnicities and, in particular, to countries where the population exhibits a short life span.

Prevalence and Predictors of Alcohol Use among School-Going Adolescents in Panama: A Population-Based Cross-Sectional Study.

This study investigated the prevalence and predictors of alcohol use among school-going-age adolescents in Panama. Using a national school-based cross-sectional survey, data from a proportionate sample of school-going adolescents aged 13-17 years were obtained from the 2018 Panama Global School-based Student Health Survey [GSHS]. Data were analysed with a Pearson's Chi-square test and weighted binary logistic regression. The results were reported with their corresponding adjusted odds ratio (AOR) at a 95% confidence interval (CI) and level of significance set at p < 0.05. The prevalence of alcohol use among adolescents in Panama was 30.6%. The odds of alcohol use were lower among adolescents in a lower grade than those in upper grades, and lower in those who did not eat from a restaurant than those who ate from a restaurant. Further, the likelihood of alcohol use was significantly high among those who engaged in physical fights, were seriously injured, were mostly worried, and whose parents used any form of tobacco. Other results showed that the odds of alcohol use were high among sedentary respondents, those who had multiple sexual partners and those who used amphetamines. Based on the present findings, a collaborative approach (i.e., stakeholders- the Ministry of Social Development and the Ministry of Education- community-individual levels) towards the development and adherence of appropriate interventions aimed at reducing alcohol use is required in Panama. Specific preventive interventions would be fundamental in promoting a positive school climate to help reduce adolescents' alcohol use and, perhaps, other anti-social behaviours (e.g., physical fights and bullying).

Prediction and analysis of trends in the nutritional status of children under 5 years in Iran: reanalysis of the results of national surveys conducted between 1998 and 2020.

Malnutrition is a major public health problem, especially in developing countries. The aim of this study was to analyze the trend in malnutrition among children under 5 years of age in Iran over recent decades and to estimate malnutrition status for 2020. This study took the form of a secondary analysis of the reports and data from three cross-sectional national surveys on children's nutritional status conducted between 1998 and 2017. Anthropometric indices, including markers of underweight, wasting, stunting, overweight, and obesity, were used as indicators of the nutritional status of children under 5 years. Malnutrition indicators are reported separately based on regional food security status. Linear mixed-effects modeling was used to predict the status of malnutrition indicators for 2020. The results of this study indicated a downward trend in the prevalence of stunting, underweight, and wasting, from 15.4 to 4.8%, 10.9 to 4.3%, and 4.9 to 4.3%, respectively, between 1998 and 2017. The proportion of children at risk of overweight and prevalence of childhood overweight/obesity showed a downward trend between 2010 and 2017, from 3.73 to 3.02% and from 12.1 to 10.3%, respectively. However, the trend varied between different provinces. Estimates of the prevalence of malnutrition in 2020 also indicated a decrease in the prevalence of all indicators among children. Despite the decreasing trend in malnutrition over the past three decades, the prevalence of stunting, underweight, and wasting is still high in food-insecure provinces. Moreover, following the COVID-19 pandemic and its economic consequences, an increase in the prevalence of malnutrition, especially in food-insecure provinces, is plausible.

COVID-19 vaccine hesitancy and social contact patterns in Pakistan: results from a national cross-sectional survey

BackgroundVaccination is a key tool against COVID-19. However, in many settings it is not clear how acceptable COVID-19 vaccination is among the general population, or how hesitancy correlates with risk of disease acquisition. In this study we conducted a nationally representative survey in Pakistan to measure vaccination perceptions and social contacts in the context of COVID-19 control measures and vaccination programmes.MethodsWe conducted a vaccine perception and social contact survey with 3,658 respondents across five provinces in Pakistan, between 31 May and 29 June 2021. Respondents were asked a series of vaccine perceptions questions, to report all direct physical and non-physical contacts made the previous day, and a number of other questions regarding the social and economic impact of COVID-19 and control measures. We examined variation in perceptions and contact patterns by geographic and demographic factors. We describe knowledge, experiences and perceived risks of COVID-19. We explored variation in contact patterns by individual characteristics and vaccine hesitancy, and compared to patterns from non-pandemic periods.ResultsSelf-reported adherence to self-isolation guidelines was poor, and 51% of respondents did not know where to access a COVID-19 test. Although 48.1% of participants agreed that they would get a vaccine if offered, vaccine hesitancy was higher than in previous surveys, and greatest in Sindh and Baluchistan provinces and among respondents of lower socioeconomic status. Participants reported a median of 5 contacts the previous day (IQR: 3–5, mean 14.0, 95%CI: 13.2, 14.9). There were no substantial differences in the number of contacts reported by individual characteristics, but contacts varied substantially among respondents reporting more or less vaccine hesitancy. Contacts were highly assortative, particularly outside the household where 97% of men's contacts were with other men. We estimate that social contacts were 9% lower than before the COVID-19 pandemic.ConclusionsAlthough the perceived risk of COVID-19 in Pakistan is low in the general population, around half of participants in this survey indicated they would get vaccinated if offered. Vaccine impact studies which do not account for correlation between social contacts and vaccine hesitancy may incorrectly estimate the impact of vaccines, for example, if unvaccinated people have more contacts.

Geographic Variations in the Prevalence, Awareness, Treatment, and Control of Dyslipidemia among Chinese Adults in 2018–2019: A Cross-sectional Study

ObjectiveTo investigate the spatial patterns of the prevalence, awareness, treatment, and control rates of dyslipidemia at the provincial level in China. MethodsA national and provincial representative cross-sectional survey was conducted among 178,558 Chinese adults in 31 provinces in mainland China in 2018–2019, using a multi-stage, stratified, cluster-randomized sampling design. Subjects, as households, were selected, followed by a home visit to collect information. Both descriptive and linear regression procedures were applied in the analyses. ResultsThe overall prevalence of dyslipidemia was 35.6%, and wide geographic variations of prevalence, treatment, and control rates of dyslipidemia were identified among 178,558 eligible participants with a mean age of 55.1 ± 13.8 years. The highest-lowest difference regarding the provincial level prevalence rates were 19.7% vs. 2.1% for high low-density lipoprotein cholesterol, 16.7% vs. 2.5% for high total cholesterol, 35.9% vs. 5.4% for high triglycerides, and 31.4% vs. 10.5% for low high-density lipoprotein cholesterol. The treatment rate of dyslipidemia was correlated with the socio-demographic index (P < 0.001), urbanization rate (P = 0.01), and affordable basic technologies and essential medicines (P < 0.001). ConclusionPrevailing dyslipidemia among the Chinese population and its wide geographic variations in prevalence, treatment, and control suggest that China needs both integrated and localized public health strategies across provinces to improve lipid management.

"The best of a bad situation?" A mixed methods survey exploring patients' perspectives on physiotherapy-led online group exercise programmes.

The COVID-19 pandemic saw the migration of many physiotherapy-led group exercise programmes towards online platforms. This online survey aimed to ascertain the patients' views of online group exercise programmes (OGEP), including their satisfaction with various aspects of these programmes, the advantages and disadvantages and usefulness beyond the pandemic. A mixed-methods design was utilised with a cross-sectional national online survey of patients who had previously attended a physiotherapy-led OGEP in Ireland. The survey collected both qualitative and quantitative data. Descriptive statistics were used to summarise the ordinal and continuous data and conventional content analysis was used to analyse the free-text responses. In total, 94 patients completed the surveys. Fifty percent of patients questioned would prefer in-person classes. Despite only a quarter of patient respondents preferring online classes going forward, satisfaction with the OGEPs was high with nearly 95% of respondents somewhat or extremely satisfied. Decreased travel and convenience were cited as the main benefits of OGEPs. Decreased social interaction and decreased direct observation by the physiotherapist were the main disadvantages cited. Patients expressed high satisfaction rates overall with online classes, but would value more opportunities for social interaction. Although 50% of respondents would choose in-person classes in the future, offering both online and in-person classes beyond the pandemic may help to suit the needs of all patients and improve attendance and adherence.
