A multi-level analysis of prevalence and factors associated with caesarean section in Nigeria.

The choice of caesarean section (CS) plays a significant role in maternal and neonatal health. However, suboptimal CS uptake suggests unmet obstetric care leading to adverse maternal and neonatal health. Considering that maternal health problems in Nigeria remain a public health problem, this present study aims to assess the prevalence and multilevel factors associated with caesarean section among women of reproductive age in Nigeria. Data from the 2018 Nigeria Demographic and Health Survey were analysed. Our analyses included 19,964 women of reproductive age, with their last birth within five years preceding the survey. Multilevel logistic regression analysis was carried out to examine the predictors of the caesarean section in Nigeria. The prevalence of CS among women of reproductive age in Nigeria was 3.11%. Women from the Yoruba ethnic group [aOR = 0.52; 95%(CI = (0.32-0.84)], with two children [aOR = 0.67; 95%(CI = 0.52-0.88)], three children [aOR = 0.49; 95%(CI = 0.36-0.66)], four children and above [aOR = 0.34; 95%(CI = 0.26-0.46)], those who practised Islam [aOR = 0.74; 95%(CI = (0.56-0.99)], and those that had a normal weighted baby [aOR = 0.73; 95%(CI = 0.60-0.99)] were less likely to report having a CS in Nigeria compared to those from Hausa/Fulani ethnic group, those who had one child, those who practised Christianity, and those who had a high weighted baby. Also, women residing in rural areas [aOR = 0.79; 95% (CI = (0.63-0.99)] and the South-South [aOR = 0.65; 95%(CI = (0.46-0.92)] were less likely to have CS compared to those residing in urban areas and North Central. The study concluded that several individual and community-level factors, such as religious belief, number of children, ethnicity, place of residence, and region of residence, were associated with CS utilisation in Nigeria. Our study highlights the need for different regional, local, and cultural contexts for evidence-based policy and programmatic efforts to facilitate equitable access to a caesarean section in Nigeria.

A high sense of coherence can mitigate suicidal ideation associated with insomnia.

The present study aimed to investigate whether insomnia is associated with suicidal ideation (SI) among Japanese workers by conducting a multi-level analysis with sense of coherence (SOC) as a random effect. A cross-sectional survey was conducted among 19,481 workers in Tsukuba, Japan. Data from 7,175 participants aged 20-65 years were included in the analysis. The Athens Insomnia Scale (AIS) was used as the independent variable, and SI over the past year was used as the dependent variable. SOC was measured using the five-point SOC-13 scale, and socioeconomic and health factors were investigated as covariates. Participants were divided into three groups (low, medium, and high) based on their SOC scores. Multilevel logistic regression analysis was performed to calculate odds ratios (OR) and 95% confidence intervals (95% CI). In the high-SOC group, only one person had SI. In a multi-level logistic analysis that excluded the high SOC group, insomnia was found to be associated with SI (OR = 2.26, 95% CI [1.75, 2.93]). Furthermore, the AIS sub-items "Final awakening earlier than desired" (OR = 1.26, 95% CI [1.05, 1.50]) and "Sense of well-being during the day" (OR = 1.63, 95% CI [1.34, 1.99]) were associated with SI. 8.95% or 11% of the variation in the presence or absence of SI was found to be explained by differences between SOC groups. The study highlights that insomnia is associated with SI, and that high SOC may reduce SI even under insomnia. Future longitudinal studies are needed to confirm whether high SOC reduces SI due to insomnia.

Does Athlete Status Explain Sexual Violence Victimization and Perpetration on College Campuses? A Socio-Ecological Study.

In the United States, college students have been identified as a high-risk group for sexual violence (SV) victimization and perpetration, with one in three women and one in four men experiencing SV in their lifetimes. Therefore, studies investigating both perpetration and victimization across genders are pertinent. Additionally, in the context of higher education, athletics is often viewed as a high-risk environment for SV. Despite established relationships between SV and intercollegiate athletics, research on this topic is not conclusive due to the heterogeneous nature of college sports, as well as a dearth of research on recreational athletes. The primary purpose of this study was to examine the differences in SV victimization and perpetration among intercollegiate, recreational, and non-athlete populations. Additional context was provided by exploring variables at multiple levels of the socio-ecological model for violence prevention, as these factors can be important aspects of a person's development and may inform behavior. Utilizing a sample of 62,996 students from 199 institutions of higher education in the United States, multilevel logistic regression analyses were conducted to assess individual- (i.e., personal demographics), relationship- (i.e., athlete status), and community-level (i.e., institutional characteristics) predictors of SV victimization and perpetration. The results indicated that recreational athletes are the most at-risk group, experiencing and perpetrating SV at higher rates than non-athletes. Results on institutional status and individual characteristics, as well as implications for practitioners and future research is discussed.

Weekend effect on 30-day mortality for ischemic and hemorrhagic stroke analyzed using severity index and staffing level.

Previous studies on the weekend effect-a phenomenon where stroke outcomes differ depending on whether the stroke occurred on a weekend-mostly targeted ischemic stroke and showed inconsistent results. Thus, we investigated the weekend effect on 30-day mortality in patients with ischemic or hemorrhagic stroke considering the confounding effect of stroke severity and staffing level. We retrospectively analyzed data of patients hospitalized for ischemic or hemorrhagic stroke between January 1, 2015, and December 31, 2018, which were extracted from the claims database of the National Health Insurance System and the Medical Resource Report by the Health Insurance Review & Assessment Service. The primary outcome measure was 30-day all-cause mortality. In total, 278,632 patients were included, among whom 84,240 and 194,392 had a hemorrhagic and ischemic stroke, respectively, with 25.8% and 25.1% of patients, respectively, being hospitalized during the weekend. Patients admitted on weekends had significantly higher 30-day mortality rates (hemorrhagic stroke 16.84%>15.55%, p<0.0001; ischemic stroke 5.06%>4.92%, p<0.0001). However, in the multi-level logistic regression analysis adjusted for case-mix, pre-hospital, and hospital level factors, the weekend effect remained consistent in patients with hemorrhagic stroke (odds ratio [OR] 1.05, 95% confidence interval [CI] 1.00-1.10), while the association was no longer evident in patients with ischemic stroke (OR 1.01, 95% CI 0.96-1.06). Weekend admission for hemorrhagic stroke was significantly associated with a higher mortality rate after adjusting for confounding factors. Further studies are required to understand factors contributing to mortality during weekend admission.

Multilevel logistic regression analysis of factors associated with delivery care service utilization among childbearing women in Ethiopia.

Delivery service utilization is one of the key and proven interventions to reduce maternal death during childbearing. In Ethiopia, the utilization of health facilities for delivery service is still at a lower level. This study intends to model the determinant factors for the delivery care service utilization of childbearing mothers in Ethiopia using the 2016 Ethiopian demographic and health survey data. A cross-sectional study design was selected to assess factors associated with delivery care among mothers who had at least one child in the last 5 years before the survey aged 15-49 years in the data. Among these eligible mothers, 3,052 (27.7%) mothers had received delivery service care from health professionals. The results of multilevel logistic regression indicated that those at age 35-49 years (AOR = 0.7808, 95% CI: 0.5965-1.1132), an urban place of residence (AOR = 5.849 95% CI: 4.2755-8.0021), woman's higher level of education (AOR = 3.484, 95% CI: 2.0214-6.0038) and partner's higher educational level (AOR = 1.9335, 95% CI: 3,808-2.07352), household wealth index (AOR = 1.99, 95% CI: 1.724-2.3122), most every day exposed to mass media (AOR = 3.068, 95% CI: 1.456-6.4624), 2-4 birth order number (AOR = 0.604, 95% CI: 0.51845-1.4213), using contraceptive type (AOR = 1.4584, 95% CI: 1.2591-1.6249) and visiting more than 4 antenatal care visits (AOR = 7.574, 95% CI: 6.4824-8.84896) were more likely to give birth at a health facility compared to their counterparts. The woman's and partner's educational level, household wealth index, exposure to mass media and number of antenatal care visits had a positive association with delivery assistance whereas birth order had a negative association. The findings of this study were valuable implications to support strategies and interventions to address delivery care service in Ethiopia.

Alcohol Use Disorder Visits and Suicide Ideation Diagnosis: Racial/Ethnic Differences at Emergency Departments

Nationally, suicide ideation prevalence is comparable among White, American Indian/Alaska Native, Black, and Hispanic adults experiencing alcohol use disorder. This study examines whether such comparability extends to the probability of receiving a suicide ideation diagnosis when presenting with alcohol use disorder at emergency departments. The probability of hospitalization following such diagnosis is examined as well. National Emergency Department Sample (2019) data were used. Logistic and multilevel logistic regression analyses were performed in 2022-2023 with suicide ideation diagnosis and subsequent hospitalization as the outcome variables. Control variables included demographics, payor, alcohol use disorder level, comorbidities, and emergency department facility. Adjusted probabilities were computed. Age-adjusted probabilities of suicide ideation diagnoses for American Indian/Alaska Native, Black, and Hispanic patients with alcohol use disorder were 5.4%, 6.7%, and 4.9% (95% CIs=3.7, 7.1; 6.0, 7.4; 4.4, 5.4), respectively; all less than that for White counterparts (8.7%; 95% CI=8.2, 9.2). Among patients with alcohol use disorder plus suicide ideation diagnoses, the age-adjusted probability of hospitalization for American Indians/Alaska Natives (32.4%; 95% CI=20.9, 44.0) was less than that for Whites, Blacks, and Hispanics (49.8%, 52.3%, and 49.9%; 95% CIs=46.7, 52.8; 47.1, 57.5; and 43.9, 55.8, respectively). In regressions with multiple control variables, the racial/ethnic differences remained statistically significant (p<0.05). Diagnosis of suicide ideation, a key step in emergency department suicide prevention care, occurred significantly less often for patients of color with alcohol use disorder than for White counterparts. American Indians/Alaska Natives, the racial/ethnic group known to have the nation's highest suicide rate, had the lowest probability of being hospitalized after a diagnosis of alcohol use disorder plus suicide ideation.

Women's utilisation of quality antenatal care, intrapartum care and postnatal care services in Ethiopia: a population-based study using the demographic and health survey data

ObjectiveThis study sought to investigate the level and determinants of receiving quality antenatal care (ANC), intrapartum care, and postnatal care (PNC) services by women in Ethiopia. The quality of care a woman receives during ANC, intrapartum care, and PNC services affects the health of the woman and her child and her likelihood of seeking care in the future.MethodsData from the nationally representative Ethiopia Mini Demographic and Health Survey 2019 were analysed for 5,527 mothers who gave birth within five years preceding the survey. We defined quality ANC as having: blood pressure measurement, urine and blood tests, informed of danger signs, iron supplementation, and nutritional counselling during ANC services; quality intrapartum care as having: a health facility birth, skilled birth assistance, and a newborn put to the breast within one hour of birth during intrapartum care services; and quality PNC as having: PNC within two days; cord examination; temperature measurement, and counselling on danger signs and breastfeeding of the newborn; and healthcare provider's observation of breastfeeding during PNC services. We used multilevel mixed-effects logistic regression analyses specifying three-level models: a woman/household, a cluster, and an administrative region to determine predictors of each care quality. The analyses employed sampling weights and were adjusted for sampling design.ResultsThirty-six percent (n = 1,048), 43% (n = 1,485), and 21% (n = 374) women received quality ANC, intrapartum care and PNC services, respectively. Private healthcare facilities provided higher-quality ANC and PNC but poor-quality intrapartum care, compared to public health facilities. Having four or more ANC visits, commencing ANC during the first trimester, and higher women's education levels and household wealth indices were positive predictors of quality ANC use. Government health posts were less likely to provide quality ANC. Wealthier, urban-residing women with education and four or more ANC contacts were more likely to receive quality intrapartum care. Women who received quality ANC and skilled birth assistance were more likely to receive quality PNC. Teenage mothers were more likely to receive quality intrapartum care, but were less likely to receive quality PNC than mothers aged 20–49.ConclusionsWe recommend standardizing the contents of ANC provided in all healthcare facilities; and promoting early and four or more ANC contacts, effectiveness, sensitivity and vigilance of care provided to teenage mothers, and women's education and economic empowerment.

Turnover intention and its associated factors among nurses: a multi-center cross-sectional study.

The purpose of our study was to assess the turnover intention of nurses in China and examine the associated factors. Since the world population ages, the demand for nurses has kept growing, and the shortage of nurses and high turnover rates are concerned with the quality of care. Thus, understanding nurses' turnover intention and the relevant factors could provide nurse managers with strategies to address the modifiable factors to decrease the turnover rate of nurses. A multi-center cross-sectional study was conducted on a total of 1,854 nurses working in 15 hospitals in China. Data were collected using a self-designed demographic questionnaire, the Turnover Intention Scale, the Job Satisfaction Scale, the Pay Level Satisfaction Scale, the Interpersonal Conflict at Work Scale, and a single question on the sense of belonging to the hospital. Most nurses (n = 1286, 69.4%) had a high level of turnover intention. Multilevel logistic regression analysis demonstrated that nurses being single (OR = 1.366, p < 0.05), with a junior college or below (OR = 0.381, p < 0.01), being a clinical nurse (OR = 1.913, p < 0.01), having higher pay level (OR = 0.596, p < 0.001), having higher job satisfaction (OR = 0.406, p < 0.001), having conflicts with colleagues (OR = 1.400, p < 0.05), and having a higher sense of belonging to the hospital (OR = 0.532, p < 0.001) proved to affect nurses' turnover intention. This study extended the knowledge about the factors associated with nurses' intention to leave, which led to the turnover of nurses, and is one of the main contributors to the current shortage of nurses. This study provided new approaches to decreasing the turnover rate of nurses. Effective management strategies may mitigate nurses' turnover intention.

Exploring spatial patterns, and identifying factors associated with insufficient cash or food received from a productive safety net program among eligible households in Ethiopia: a spatial and multilevel analysis as an input for international food aid programmers

BackgroundIn low-income countries, households’ food insecurity and the undernutrition of children are the main health problems. Ethiopia is vulnerable to food insecurity and undernutrition among children because its agricultural production system is traditional. Hence, the productive safety net program (PSNP) is implemented as a social protection system to combat food insecurity and enhance agricultural productivity by providing cash or food assistance to eligible households. So, this study aimed to explore spatial patterns of households’ insufficient cash or food receiving from PSNP, and identify its associated factors in Ethiopia.MethodsThe 2019 Ethiopian Mini Demographic and Health Survey dataset was used. A total of 8595 households were included in this study. Data management and descriptive analysis were done using STATA version 15 software and Microsoft Office Excel. ArcMap version 10.7 software was used for spatial exploration and visualization. SaTScan version 9.5 software was used for spatial scan statistics reports. In the multilevel mixed effect logistic regression analysis, explanatory variables with a p-value of less than 0.05 were considered significant factors.ResultsOverall, 13.5% (95% CI: 12.81–14.27%) of the households’ level beneficiaries received cash or food from PSNP. The spatial distribution of households’ benficiaries received cash or food from PSNP was not random, and good access to cash or food from PSNP was detected in Addis Ababa, SNNPR, Amhara, and Oromia regions. Households’ heads aged 25–34 (AOR:1.43, 95% CI: 1.02, 2.00), 35–44 (AOR: 2.41, 95% CI: 1.72, 3.37), and > 34 (AOR: 2.54, 95% CI: 1.83, 3.51) years, being female (AOR: 1.51, 95% CI: 1.27,1.79), poor households (AOR: 1.91, 95% CI:1.52, 2.39), Amhara (AOR:.14, 95% CI: .06, .39) and Oromia (AOR:.36, 95% CI:.12, 0.91) regions, being rural residents (AOR:2.18, 95% CI: 1.21,3.94), and enrollment in CBHS (AOR: 3.34, 95% CI:2.69,4.16) are statistically significant factors.ConclusionsHouseholds have limited access to cash or food from the PSNP. Households in Addis Ababa, SNNPR, Amhara, and Oromia regions are more likely to receive benefits from PSNP. Encouraging poor and rural households to receive benefits from the PSNP and raise awareness among beneficiaries to use the benefits they received for productivity purposes. Stakeholders would ensure the eligibility criteria and pay close attention to the hotspot areas.

Relationship between history of hormonal contraceptive use and anaemia status among women in sub-Saharan Africa: A large population-based study.

Anaemia among women has been reported to be a significant contributor to hemorrhage, exacerbated risk of stillbirths, miscarriages, and maternal mortalities. Hence, understanding the factors associated with anaemia is imperative to develop preventive strategies. We examined the association between history of hormonal contraceptive use and risk of anaemia among women in sub-Saharan Africa. We analyzed data from the recent Demographic and Health Surveys (DHS) of sixteen countries in sub-Saharan Africa. Countries with recent DHSs conducted from 2015 to 2020 were included in the study. A total of 88,474 women of reproductive age were included. We used percentages to summarize the prevalence of hormonal contraceptives and anaemia among women of reproductive age. We used multilevel binary logistic regression analysis to examine the association between hormonal contraceptives and anaemia. We presented the results using crude odds ratio (cOR) and adjusted odds ratios (aOR), with their respective 95 percent confidence intervals (95% CIs). On the average, 16.2% of women are using hormonal contraceptives and this ranged from 7.2% in Burundi to 37.7% in Zimbabwe. The pooled prevalence of anaemia was 41%, ranging from 13.5% in Rwanda to 58.0% in Benin. Women who used hormonal contraceptives were less likely to be anaemic compared to those who were not using hormonal contraceptives (aOR = 0.56; 95%CI = 0.53, 0.59). At the country-level, hormonal contraceptive use was associated with a reduced likelihood of anaemia in 14 countries, except for Cameroon and Guinea. The study underscores the importance of promoting the use of hormonal contraceptives in communities and regions that have a high burden of anaemia among women. Specifically, health promotion interventions aimed at promoting the use of hormonal contraceptives among women must be tailored to meet the needs of adolescents, multiparous women, those in the poorest wealth index, and women in union as these sub-populations were at significantly higher risk of anaemia in sub-Saharan Africa.

Retinal Nerve Fiber Layer Optical Texture Analysis: Detecting Axonal Fiber Bundle Defects in Patients with Ocular Hypertension

To apply retinal nerve fiber layer (RNFL) optical texture analysis (ROTA) to investigate the prevalence, patterns, and risk factors of RNFL defects in patients with ocular hypertension (OHT) who showed normal optic disc and RNFL configuration in clinical examination, normal RNFL thickness on OCT analysis, and normal visual field (VF) results. Cross-sectional study. Six hundred eyes of 306 patients with OHT. All participants underwent clinical examination of the optic disc and RNFL, OCT RNFL imaging, and 24-2 standard automated perimetry. To detect RNFL defects, ROTA was applied. The risk score for glaucoma development was calculated according to the Ocular Hypertension Treatment Study and European Glaucoma Prevention Study (OHTS-EGPS) risk prediction model. Risk factors associated with RNFL defects were analyzed using multilevel logistic regression analysis. Prevalence of RNFL defects. The average intraocular pressure (IOP) measured from 3 separate visits within 6 months was 24.9 ± 1.8 mmHg for the eye with higher IOP and 23.7 ± 1.7 mmHg for the eye with lower IOP; the respective central corneal thicknesses were 568.7 ± 30.8 μm and 568.8 ± 31.2 μm. Of 306 patients with OHT, 10.8% (33 patients, 37 eyes) demonstrated RNFL defects in ROTA in at least 1 eye. Of the 37 eyes with RNFL defects, the superior arcuate bundle was the most frequently involved (62.2%), followed by the superior papillomacular bundle (27.0%) and the inferior papillomacular bundle (21.6%). Papillofoveal bundle defects were observed in 10.8% of eyes. The smallest RNFL defect spanned 0.0° along Bruch's membrane opening margin, whereas the widest RNFL defect extended over 29.3°. Age (years) (odds ratio [OR], 1.08; 95% confidence interval [CI], 1.03-1.13), VF pattern standard deviation (decibels [dB]) (OR, 1.82; 95% CI, 1.01-3.29), cup volume (mm3) (OR, 1.24; 95% CI, 1.01-1.53), and the OHTS-EPGS risk score (OR, 1.04; 95% CI, 1.01-1.07) were associated with RNFL defects. A considerable proportion of patients with OHT who showed no signs of optic disc and RNFL thickness abnormalities on clinical and OCT examination exhibited RNFL defects on ROTA. Axonal fiber bundle defects on ROTA may represent the earliest discernible sign of glaucoma in the glaucoma continuum. Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.

Trends in dental care utilisation among the elderly using longitudinal data from 14 European countries: A multilevel analysis.

The use of dental care among older people is low compared to other forms of health care, with significant health consequences. However, the evidence on the extent to which countries' welfare systems and socio-economic factors influence the uptake of dental care by older people is limited. This study aimed to describe trends of dental care utilisation, and to compare use of dental care with other types of healthcare services among the elderly, considering different socio-economic factors and welfare systems in European countries. Multilevel logistic regression analysis was performed using longitudinal data from four waves (between Wave 5 and 8) of the Survey of Health, Ageing and Retirement in Europe database, with a follow-up period of 7 years. The study sample included 20,803 respondents aged 50 years or older from 14 European countries. The annual dental care attendance was the highest in Scandinavian countries (85.7%), however, improving trends of dental attendance was recognized in Southern and Bismarckian countries (p<0.001). The difference in use of dental care services between socio-economic groups was expanding over time regarding low- and high-income level and residential area. A more marked difference was observed between social groups in dental care utilisation compared to other forms of care. Income level and unemployed status had significant effect on forgoing dental care due to cost and unavailability. The observed differences between socioeconomic groups may highlight the health consequences of the different organization and financing of dental care. The elderly population could benefit from adopting policies aiming to reduce the financial barriers to dental care usage, especially in Southern and Eastern European countries.

Regional practice variation in induction of labor in the Netherlands: Does it matter? A multilevel analysis of the association between induction rates and perinatal and maternal outcomes.

Practice variation in healthcare is a complex issue. We focused on practice variation in induction of labor between maternity care networks in the Netherlands. These collaborations of hospitals and midwifery practices are jointly responsible for providing high-quality maternity care. We explored the association between induction rates and maternal and perinatal outcomes. In a retrospective population-based cohort study, we included records of 184,422 women who had a singleton, vertex birth of their first child after a gestation of at least 37 weeks in the years 2016-2018. We calculated induction rates for each maternity care network. We divided networks in induction rate categories: lowest (Q1), moderate (Q2-3) and highest quartile (Q4). We explored the association of these categories with unplanned caesarean sections, unfavorable maternal outcomes and adverse perinatal outcomes using descriptive statistics and multilevel logistic regression analysis corrected for population characteristics. The induction rate ranged from 14.3% to 41.1% (mean 24.4%, SD 5.3). Women in Q1 had fewer unplanned caesarean sections (Q1: 10.2%, Q2-3: 12.1%; Q4: 12.8%), less unfavorable maternal outcomes (Q1: 33.8%; Q2-3: 35.7%; Q4: 36.3%) and less adverse perinatal outcomes (Q1: 1.0%; Q2-3: 1.1%; Q4: 1.3%). The multilevel analysis showed a lower unplanned caesarean section rate in Q1 in comparison with reference category Q2-3 (OR 0.83; p = .009). The unplanned caesarean section rate in Q4 was similar to the reference category. No significant associations with unfavorable maternal or adverse perinatal outcomes were observed. Practice variation in labor induction is high in Dutch maternity care networks, with limited association with maternal outcomes and no association with perinatal outcomes. Networks with low induction rates had lower unplanned caesarean section rates compared to networks with moderate rates. Further in-depth research is necessary to understand the mechanisms that contribute to practice variation and the observed association with unplanned caesarean sections.

The effectiveness of topical fluoride agents on preventing development of approximal caries in primary teeth: a randomized clinical trial

BackgroundThis 18-month randomized clinical trial aimed to compare the effectiveness of two topical fluoride applications versus placebo control on preventing development of approximal caries in primary teeth.MethodsPreschool children were recruited if they had at least one initial approximal carious lesion at the distal surface of the canines, both approximal surfaces of the first molars, or the mesial surface of the second molars assessed from bitewing radiographs. The participants were randomly allocated into 3 intervention groups: Group 1 (placebo control), Group 2 (5% sodium fluoride [NaF] varnish), and Group 3 (38% silver diamine fluoride [SDF]). All agents were applied semiannually. Two calibrated examiners evaluated the caries development from bitewing radiographs. Caries development was recorded when the baseline sound surface or initial approximal carious lesion surface developed dentin caries (beyond the outer one-third of dentine) at the follow-up examination. The intention-to-treat approach was adopted. The Chi-square test was used to analyze the effectiveness of topical fluoride agents in preventing approximal caries development and the effect of other variables. The multi-level logistic regression analysis was performed to assess the relative effectiveness of topical fluoride agents in preventing approximal caries development at the 18-month follow-up.ResultsAt baseline, 190 participants with 2,685 sound or initial carries at the approximal surfaces were recruited. No differences in participant demographic backgrounds, oral health related habits, or caries experience were observed among the 3 groups (P > 0.05). After 18 months, 155 (82%) participants remained in the study. The rates of developing approximal caries in Groups 1, 2, and 3 were 24.1%, 17.1%, and 27.2%, respectively (P < 0.001, χ2 test). After adjusting for confounding factors and clustering effect, the multilevel logistic regression analysis showed no differences in caries development rates between the 3 groups (P > 0.05). Tooth type and the extent of a carious lesion at baseline were the significant factors for caries development.ConclusionAt 18-month follow-up, after adjusting for confounding factors and clustering effect, there were no statistically significant differences in preventing of approximal caries development between the semiannual application of 5%NaF, 38%SDF, or placebo.Trial registrationThe study was registered in the Thai Clinical Trials Registry under the number TCTR20190315003 on 15/03/2019.

Association Between Alcohol Expectancy and Drinking Behaviors in Summer Vacation and Last Year Among College Students.

Drinking in summer vacation, as an important part of college students' drinking behavior, has rarely been studied. At present, there is no research to explore the association between alcohol expectancy and college students' drinking behavior during the summer vacation. A total of 487 college students were selected from three universities in Chongqing from July 30, 2017, to August 30, 2017, by cluster sampling. The electronic questionnaires were distributed to complete the anonymous survey related to drinking. The questionnaire on drinking mainly included baseline characteristics, influencing factors related to drinking, drinking behavior in the last year and summer vacation, and alcohol expectancy. Independent sample t-test and one-way ANOVA were used for multi-factor analysis. Multi-level logistic regression analysis and ordered logistic regression analysis were used for multivariate analysis. The past drinking rate in the study group was 86.24%. In the past year, the drinking rate and binge drinking rate of college students were 63.24% and 23.20%. In summer drinking, these two indicators were 29.57% and 8.42%, respectively. About 92.50% of the moderate and heavy drinking groups among college students had drinking behavior during the summer vacation. The average negative expectancy among college students was 3.26 ± 0.87 while the average positive expectancy was 2.63 ± 0.66. In drinking last year, positive expectancy was a risk factor for occasional and light drinking compared with those of non-drinkers (P<0.05). In summer vacation drinking, compared with those of non-drinkers, negative expectancy was a protective factor for occasional drinking (OR: 1.847, 95% CI: 1.293-2.638), negative expectancy and positive expectancy were both influencing factors for light drinking (P<0.05). The drinking rate in the study group was at a high level in the past. The association between alcohol expectancy and drinking behavior among college students would be different according to the period and amount of drinking.

Minimum Dietary Diversity Among Children Aged 6-59Months in East Africa Countries: A Multilevel Analysis.

Objective: To find out the determinants of minimum dietary diversity (MDD) among under-five children in East Africa based on the 2017 revised indicator. Methods: Secondary data from the demographic and health survey (DHS) of eight countries in East Africa were combined. A total of 27,223 weighted samples of children aged 6-59months were included. Multi-level logistic regression analysis was employed to identify the determinants of dietary diversity. Results: The magnitude of adequate MDD in East Africa was found to be 10.47% with 95% CI (10.12-10.84) with the lowest and highest magnitude in Ethiopia and Rwanda respectively. Having a mother in the age group of 35-49, having a mother with higher educational attainment, and having a post-natal check-up within 2months were significant factors in determining adequate MDD. Conclusion: The magnitude of adequate MDD intake among children aged 6-59months in East Africa is relatively low. Therefore, strengthening interventions focused on improving the economic status of households, the educational status of mothers, and diversified food consumption of children aged 6-59months should get priority to improve the recommended feeding practice of children.

Predictors of desire to limit childbearing among reproductive age women in high fertility regions in Ethiopia. A multilevel mixed effect analysis

BackgroundA high fertility rate can have a number of expensive consequences for developing nations, such as limiting economic growth, adversely impacting women and their children’s health, and reducing access to quality education, nutrition, and employment. The problem is more obvious in Ethipia’s high fertility regions. Therefore, this study aimed to assess predictors of desire to limit childbearing among reproductive age women in high fertility regions in Ethiopia.MethodsThe analysis was based on secondary data using the 2016 Ethiopian Demographic and Health Survey. Stata version 14 software was used for analysis. A multi-level mixed-effect logistic regression analysis was fitted. Adjusted Odds Ratio at 95% confidence interval was used to show the strength and direction of the association. Statistical significance was declared at a P- value less than 0.05.ResultsThe overall desire to limit childbearing in high fertility regions in Ethiopia was 37.7% (95% CI: 36.28, 39.17). Age; 25–34 (AOR = 3.74; 95% CI: 2.97, 4.73), 35–49 years (AOR = 14; 95% CI: 10.85, 18.06), women education; Primary education (AOR = 0.73; 95% CI: 0.61, 0.88), secondary and higher (AOR = 0.29; 95% CI: 0.19, 0.43), from the community level variables Oromia National Regional state (AOR = 5.86; 95% CI: 2.82, 12.23), high proportion of community level poverity (AOR = 0.67; 95% CI: 0.45, 0.98), and high proportion of community level media exposure (AOR = 1.53; 95% CI: 1.07, 2.19) were statistically significant factors for desire to limit childbearing in high fertility regions of Ethiopia.ConclusionNearly four in ten women had the desire to limit childbearing in high fertility regions in Ethiopia. Thus, to fulfill the women’s desire to limit childbearing, Ministry of Health and health facilities are needed to increase financial support strategies and Family planning programs that enable pregnant women from poor households to use health services. In addition, increasing community level media exposure are important interventions.

The Correlation between Adolescent Daily Breakfast Consumption and Socio-Demographic: Trends in 23 European Countries Participating in the Health Behaviour in School-Aged Children Study (2002-2018).

Breakfast is often considered the most important meal of the day and can benefit adolescent health in several ways. The aims of the present study were (1) to identify adolescents' socio-demographic (sex, family affluence and family structure) determinants of daily breakfast consumption (DBC) and (2) to describe trends in DBC among adolescents across 23 countries. Cross-sectional surveys of nationally representative samples of adolescents (aged 11, 13, and 15 years) (n = 589,737) participating in the Health Behaviour in School-aged Children (HBSC) survey from 2002 to 2018 were used. Multilevel logistic regression analyses modeled DBC over time, adjusted for family affluence, family structure and year of survey. Four countries showed an increased trend in DBC (the Netherlands, Macedonia, Slovenia, and England). A significant decrease in DBC was observed in 15 countries (Belgium-Fr, France, Germany, Croatia, Portugal, Spain, Hungary, Poland, Russian Federation, Ukraine, Denmark, Finland, Latvia, Lithuania and Sweden). In 4 countries no significant change was observed (Czech Republic, Scotland, Ireland and Norway). In most of the countries (n = 19), DBC was higher among the adolescents from high-affluence homes. In all the countries analysed, the adolescents living in two-parent households report higher DBC use than those in single-parent households. More than half of the countries showed a decrease in DBC. There is a need to implement key interventions by developing different strategies (education, incorporating educational curriculum and counselling programmes) to increase DBC. Comparing DBC patterns across HBSC countries is important for understanding regional and global trends, monitoring strategies, and developing health promotion programmes.

Area-level deprivation and handwashing behavior during the COVID-19 pandemic: A multilevel analysis on a nationwide survey in Korea

ABSTRACT This study investigated the association between area deprivation level and performance of handwashing behavior during the COVID-19 pandemic in Korean adults. This study used data from the 2015 Population and Housing Census data to measure area deprivation level. The 2020 Korea Community Health Survey was used for all other variables, including hand hygiene behavior (August through November 2020). The association between area deprivation level and practice of handwashing behavior was examined using multilevel logistic regression analysis. The study population comprised 215,676 adults aged 19 years or above. Compared to the least area deprived group, the most deprived group was more likely to not wash hands after using the restroom (OR 1.43, 95% CI 1.13–1.82), after coming home (OR 1.85, 95% CI 1.43–2.39), and using soap (OR 1.55, 95% CI 1.29–1.84). The findings suggest the importance of considering area deprivation in implementing policies that promote handwashing, particularly during a pandemic.

Recreational Marijuana Legalization, Local Retail Availability, and Alcohol and Marijuana Use and Co-Use Among California High School Students.

This study examined whether recreational marijuana legalization (RML) and local retail availability were associated with marijuana and alcohol use and co-use among adolescents. We investigated associations between RML and past-30-day marijuana and alcohol use and co-use, and moderating effects of retail availability of marijuana and alcohol, using data from the 2010-2011 to 2018-2019 California Healthy Kids Surveys (CHKS) of 9th and 11th grade students in 38 California cities. Multilevel mixed-effects logistic regression analyses were conducted, controlling for secular trends and student and city demographics. Additional analyses examined associations of RML and retail availability with co-use among subgroups of drinkers and marijuana users. For the full sample, RML was inversely associated with alcohol use but was not significantly associated with marijuana use or co-use with alcohol. However, significant interactions between RML and marijuana outlet density showed that there were increases in marijuana and alcohol co-use and alcohol following legalization in cities with higher densities of marijuana outlets. RML was positively associated with co-use among non-heavy and heavy drinkers, but inversely related to co-use among occasional and frequent marijuana users. A significant positive interaction between RML and marijuana outlet density indicated that RML was associated with increases in co-use for occasional marijuana users in cities with higher densities of marijuana outlets. RML was associated with increases in marijuana and alcohol co-use and alcohol use among California high school students, particularly those in cities with higher densities of retail cannabis stores, although this varied across alcohol and marijuana use subgroups.
