Workplace culture of health and employee physical activity: the moderating effects of gender and depression

IntroductionPromoting physical activity (PA) at work effectively decreases the risk of chronic disease and increases productivity. Despite the well-established benefits of PA, only 24% of adults meet the PA Guidelines for Americans. Advancing a culture of health (COH) may improve employees’ physical activity levels. The purpose of this study was to determine the effects of workplace culture of health, gender, and depression on employee physical activity.MethodsEmployees (n = 12,907) across 14 companies voluntarily completed the Workplace Culture of Health (COH) Scale, the Patient Health Questionnaire (PHQ-2), and questions on PA engagement. A logistic regression was performed to determine the effects of workplace COH, gender, and depression risk on the likelihood of engaging in 150 min of moderate to vigorous PA and in strength training 2 × per week.ResultsWorkplace COH scores were associated with increased odds of PA engagement (OR = 1.058, p < 0.001). Further, gender and depression risk moderated the relationship between workplace COH and PA engagement (OR = 0.80, p = 0.026). For employees at risk for depression, an increase in COH scores was associated with higher PA for men, but not women. For employees not at risk for depression, an increase in COH scores was associated with higher PA for males and females.ConclusionEstablishing a health-supportive workplace culture may increase PA, which is essential to improving population health. The differential findings by gender and depression risk illustrate the complexity of PA engagement.

Surgeon Recommendations for Physical Activity in Patients With Pediatric Hip Conditions.

While physical activity (PA) is important during youth, it is unclear if children and adolescents with developmental dysplasia of the hip (DDH), Legg-Calvé-Perthes disease (LCPD), or slipped capital femoral epiphysis (SCFE) are expected or encouraged to return to PA once they have healed. This study examines the orthopaedic surgeons' role in advising pediatric hip patients on the PA they should engage in, assessing their practice, opinions, and consensus when making recommendations. Orthopaedic surgeons were invited from member lists of 4 hip study groups. The survey included demographics, opinions regarding PA, and 10 case scenarios that queried respondents on the duration and intensity of PA as well as the restrictions on activity type that they would recommend for DDH, LCPD, or SCFE patients. Consensus was evaluated on a scale ranging from 0 to 1, with a value of 0 indicating no agreement among respondents and a value of 1 indicating complete agreement. A total of 51 orthopaedic surgeons responded. While 94% agreed that it is important for school-aged hip patients to return to PA after they have healed, 53% believed that PA may compromise the hip and contribute to the development of osteoarthritis. Average standardized consensus was 0.92 for suggesting the patient engage in some amount of PA, 0.44 for suggesting the recommended daily minimum of 60 minutes of moderate-to-vigorous physical activity (MVPA), and 0.33 for suggesting restrictions on activity type. The most frequently selected restrictions included avoiding impact activities (93%, 235/254) and contact activities (58%, 147/254), followed by weight-bearing activities (24%, 62/254). Respondents were not aware of existing PA guidelines, although 57% expressed interest in following guidelines and 39% were uncertain. While there is consensus among orthopaedic surgeons that children with chronic hip conditions should engage in PA, there is considerable variation when recommending the recommended daily MVPA minimum and placing restrictions on activity type. This study suggests interest among orthopaedic surgeons in developing PA guidelines that optimize outcomes for pediatric hip patients. Level II-Survey study.

Physical activity vital sign assessment and associated health outcomes in an underserved South African community

Abstract Background Physical activity is particularly low in South Africa and contributes to chronic conditions. This study aimed to determine physical activity levels in a South African community, using the physical activity vital sign (PAVS), and identify associations between physical activity and key health outcomes. Methods A cross-sectional study used community health workers to collect PAVS data, blood pressure and self-reported medical history from 2282 participants living in Soweto, Johannesburg. Physical activity was defined as meeting or not meeting WHO guidelines of ≥ 150 min/week. Hypertension was defined according to the International Society of Hypertension guidelines. Results The study population included 1161 women and 1121 men. Administering the PAVS was quick (29.5 ± 43.4 s). Only 19.8% of the total population reported meeting the guidelines, and it was significantly lower in women (17.6%) compared with men (22.1%). The logistic regression models demonstrated significant association between not meeting physical activity guidelines and hypertension (adjusted odd ratio [AOR] 0.77, 95% CI 0.61–0.97, p = 0.032), current smoking (AOR 0.73, 95% CI 0.55–0.97, p = 0.030) and past smoking (AOR 0.61, 95% CI 0.44–0.83, p = 0.002). Conclusions This study demonstrates the validity of using the PAVS in an underserved community. The observed associations highlight the potential of advocating physical activity as a feasible intervention for improving the health of urban-dwelling Black South Africans.

Physical Activity, Cardiovascular Status, Mortality, and Prediabetes in Hispanic and Non-Hispanic Adults

Data are limited on the association of physical activity (PA) with incident cardiovascular disease (CVD) and mortality in prediabetes, especially in racial and ethnic minority groups, including Hispanic and Latino populations. To determine the association of PA with incident CVD and mortality by prediabetes status among Hispanic or Latino and non-Hispanic adults. This cohort study included data from 2 cohorts of adults with prediabetes or normoglycemia who were free of CVD at baseline visit: the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) from baseline examination through 2017, with median (IQR) follow-up of 7.8 (7.2-8.5) years, and the Framingham Heart Study (FHS) with non-Hispanic participants from index examination through 2019, with median (IQR) follow-up of 9.6 (8.1-10.7) years. Analyses were conducted between September 1, 2022, and January 10, 2024. The primary exposure was baseline accelerometry-measured moderate to vigorous PA, insufficient vs sufficient to meet 2018 Physical Activity Guidelines for Americans (PAG) in both cohorts; additional accelerometer-measured exposures in HCHS/SOL were steps per day, sedentary behavior, and counts per min. The outcome was a composite of incident CVD or all-cause mortality, whichever came first. This cohort study included 13 223 participants: from HCHS/SOL, there were 9456 adults (all self-identified Hispanic or Latino ethnicity; survey-adjusted mean [SD] age, 38.3 [13.9] years, unweighted counts 5673 (60.0%) female; 4882 [51.6%] with normoglycemia; 4574 [48.4%] with prediabetes), and from FHS there were 3767 adults (3623 [96.2%] non-Hispanic and 140 [3.7%] Hispanic or Latino ethnicity, with 4 [0.1%] participants missing ethnicity; mean [SD] age, 54.2 [13.6] years; 2128 (56.5%) female; 2739 [72.7%] with normoglycemia; 1028 [27.3%] with prediabetes). Not meeting PAG was associated with higher risk of the composite outcome among participants with normoglycemia (vs PAG met; hazard ratio [HR], 1.85 [95% CI, 1.12-3.06]), but not among participants with prediabetes (HR, 1.07 [95% CI, 0.72-1.58]). For HCHS/SOL, no statistically significant association was found between the composite outcome and other PA metrics, although estimated HRs tended to be higher for lower activity in the normoglycemia group but not for the prediabetes group (eg, for steps less than vs at least 7000 per day, the HR was 1.58 [95% CI, 0.85-2.93] for normoglycemia vs 1.08 [95% CI 0.67-1.74] for prediabetes). While there was also no association in HCHS/SOL between the composite outcome and sedentary behavior, results were similar in the prediabetes group (HR per 30 minutes per day of sedentary behavior, 1.05 [95% CI 0.99-1.12]) and in the normoglycemia group (HR, 1.07 [95% CI 0.98-1.16]). In this cohort study of US Hispanic or Latino and non-Hispanic adults, lower moderate to vigorous PA levels were associated with CVD or mortality among participants with normoglycemia but not participants with prediabetes. Adults with prediabetes may benefit from reducing sedentary behavior and improving multiple lifestyle factors beyond improving moderate to vigorous PA alone.

UK midwives delivering physical activity advice; what are the challenges and possible solutions?

Despite physical activity (PA) providing specific health benefits during pregnancy and the postpartum period, many women report decreased PA during this time. Provision of PA advice has been found to be lacking amongst midwives due to a range of barriers. This study aimed to evaluate United Kingdom's midwives' current role and knowledge regarding the provision of PA advice to pregnant and postpartum women and identify the barriers and potential solutions. Ten UK midwives (mean work experience ± SD: 15.5 years ± 10.2) participated in semi-structured interviews between May and July 2023. Data were analysed using a deductive thematic approach following Braun and Clarke's six steps. Demographic data were collected by Microsoft Forms then summarised using Microsoft Excel. Six themes with 25 subthemes were identified as barriers and solutions in delivering PA advice. The role of midwives in providing PA advice during pregnancy; the role of midwives in providing PA advice postpartum; intrinsic barriers that limit PA advice provision (confidence, safety concerns, knowledge, and midwife's personal body habitus); extrinsic barriers that limit PA advice provision (lack of time, education, PA not a priority in care); solutions to allow midwives to promote PA (including formal PA education, and dissemination of resources); and optimising delivery of PA advice (personalized approach, interprofessional collaboration, and linking to mental health benefits). Midwives consider themselves ideally placed to provide PA advice to pregnant women, with many aware of the benefits PA provides. Despite this, there is a lack of PA advice provision and knowledge of PA guidelines. Postpartum PA advice appeared to be considered outside the remit of midwives, due to limited contact. Further research is needed to determine the current level of PA advice provision for pregnant and postpartum women and explore the role of other healthcare professionals involved in maternity care.

CSP2023: 198 - Patients’ perspectives on the World Health Organization’s physical activity guidelines: a mixed-methods survey

CSP2023: 198 - Patients’ perspectives on the World Health Organization’s physical activity guidelines: a mixed-methods survey

Proportion and Correlates of Children in the US-Affiliated Pacific Region Meeting Sleep, Screen Time, and Physical Activity Guidelines.

Limited data on 24-hour movement behaviors of children aged 5-8years exist globally. We describe the prevalence and sociodemographic associations of meeting physical activity (PA), sedentary recreational screen time (ST), and sleep guidelines among children from 11 jurisdictions in the US-Affiliated Pacific region. Cross-sectional representative data from 1192 children aged 5-8years living in the US-Affiliated Pacific region were drawn from the baseline 2012-2014 Children's Healthy Living Program. Sleep and moderate- to vigorous-intensity PA were calculated from accelerometry. ST and sociodemographic data were collected from caregiver surveys. The percentage of children meeting the Asia-Pacific 24-hour movement guidelines for PA (≥60min/d of moderate- to vigorous-intensity PA), sleep (≥9 and ≤ 11h/d) and ST (≤2h/d) were calculated. Generalized linear mixed models were used to examine associations with adiposity and sociodemographic variables. Twenty-seven percent (95% confidence interval, 24.6-30.0) of children met integrated guidelines; 98% (96.2-98.0) met PA, 78% (75.4-80.0) met sleep, and 35% (32.6-38.0) met ST guidelines. Females (adjusted odds ratio = 1.40 [95% confidence interval, 1.03-1.91]) and those living in lower-middle-income jurisdictions (2.29 [1.49-3.54]) were more likely to meet ST guidelines. Overweight children (0.62 [0.40-0.96]), those aged 8years (0.39 [0.22-0.69]), and children with caregivers of an education level of high school or beyond (0.44 [0.29-0.68]) were less likely to achieve ST guidelines. Children from midrange annual household incomes were less likely to meet combined guidelines (0.60 [0.39-0.92]). Three-quarters of children are not meeting integrated Asia-Pacific 24-hour movement guidelines. Future strategies for reducing ST and increasing integrated guidelines compliance are needed.

Cognitive Vulnerability to Mood Deterioration in an Exercise Cessation Paradigm.

Mood deterioration in response to exercise cessation is well-documented, but moderators of this effect remain unknown. This study tested the hypothesis that physically active individuals with higher levels of cognitive vulnerability (i.e., tendencies towards negative thought content and processes in response to stress or negative mood states) are at greater risk for increased anxiety and depressive symptoms when undergoing exercise cessation. Community adults meeting recommended physical activity guidelines (N=36) participated in a 4-week prospective, longitudinal study with 2 weeks each of maintained exercise and exercise cessation. Cognitive vulnerability measures included dysfunctional attitudes, brooding rumination, and cognitive reactivity (i.e., change in dysfunctional attitudes over a dysphoric mood induction). Anxiety and depression symptoms increased during exercise cessation. Brooding emerged as a risk factor for increases in Tension scores on the Profile of Mood States-Brief during exercise cessation. Future studies should explore brooding as a mediator (i.e., potential mechanism) of exercise-induced mood deterioration.

Association between the recommended volume of leisure-time physical activity and erectile dysfunction: A cross-sectional analysis of the national health and nutrition examination survey, 2001–2004

ObjectivePhysical activity-related interventions alleviate the severity of erectile dysfunction (ED), but it is unknown whether the recommended volume of physical activity (PA) or a higher level of physical activity reduces the likelihood of ED in adult males. We aimed to evaluate the association between the recommended volume of PA and ED among US male adults. DesignA nationally representative cross-sectional survey. SettingNational Health and Nutrition Examination Survey 2001–2004. ParticipantsA total of 2509 men aged ≥20 years were enrolled. Primary and secondary outcome measuresED and PA were assessed by a standardised self-report questionnaire. Weighted logistic regression analysis and spline fitting were used to assess the relationship between PA volume and the odds of ED. ResultsAmong 2509 US adult males, the mean (standard error) age was 43.7 (0.46) years. A total of 61.1 % of men reached the recommended volume of aerobic PA. Compared with participants not meeting the PA guidelines, individuals who had recommended aerobic activities demonstrated a 34 % reduction in the odds of having ED (OR 0.66, 95 % CI 0.48–0.90; p = 0.011). Notably, according to the restricted cubic spline, we revealed a dose‒response pattern between PA volume and reduced odds of ED, even when exceeding the recommended PA levels. When compared to males with moderate-equivalent PA of less than 150 min/week, the odds of ED in those with moderate-equivalent PA levels of 150–300 min/week and >300 min/week decreased by 22 % and 39 %, respectively. Compared with participants who did not meet the PA guidelines, the multivariable-adjusted ORs (95 % CIs) of ED associated with adequate PA volumes were 0.37 (0.22–0.61) among non-smokers and 0.85 (0.57–1.25) among current smokers (p for interaction = 0.023). Conclusions and RelevanceOur findings supported the benefit of meeting the guideline-recommended PA equivalents or higher volumes for ED prevention. However, PA-related benefit might be significantly diminished by smoking.

Compliance with the 24-hour movement behavior guidelines and the impact of sleep methods among toddler, preschool, and school-aged children enrolled in the Guelph Family Health Study

Canadian movement guidelines focused on physical activity (PA), sleep, and screen time support childhood development and reduce the risk of chronic disease. Accelerometers are often used to capture these behaviors; however, they are limited in their ability to record daytime sleep due to potential misclassification. ObjectivesThe objectives of this study were to 1) determine the prevalence of children enrolled in the Guelph Family Health Study who met the guidelines and to 2) compare the impact of different sleep measurement methods. Design/methodsToddlers (1.5–<3 years; n = 128; valid data for all movement behaviors, n = 70), preschoolers (3–<5 years; n = 143; valid data for all movement behaviors, n = 104), and school-aged (5–<6 years; n = 49; valid data for all movement behaviors, n = 31) children were included. Screen time and sleep habits were obtained through parental report and published normative data. PA and sleep were recorded using accelerometers (wGT3X-BT ActiGraph; right hip). ResultsIt was found that 66 % of toddler, 44 % of preschool, and 63 % of school-aged children met the screen time guidelines. Further, 63 % of toddler, 98 % of preschooler, and 80 % of school-aged children met PA guidelines. Sleep guideline compliance ranged from 3 % to 83 % in toddler, 27 % to 92 % in preschooler, and 32 % to 90 % in school-aged children. These proportions were found to be significantly different (Cochran's Q and McNemar's tests). ConclusionsNearly all children met PA guidelines. In contrast, less than half to two-thirds met screen time guidelines. Compliance with sleep guidelines varied substantially with measurement method, highlighting the need for standardization.

Determinants of physical activity promotion in primary care from the patient perspective of people at risk of or living with chronic disease: a COM-B analysis

BackgroundChronic disease (CD) accounts for more than half of the overall global disease burden and physical activity (PA) is an established evidence-based strategy for the prevention and management of CD. Global policy emphasises the value of embedding PA into primary healthcare, highlighting the positive effects on PA behaviour. However, there is limited implementation of PA protocols in primary care, and research is needed to guide its integration into routine practice. The voice of the patient is underrepresented in the literature, resulting in the absence of critical insights into determinants of PA promotion in primary care. The purpose of the research was to identify the perspectives of people at risk of or living with CD on the determinants of PA promotion in primary care and to map these determinants across the six COM-B constructs.MethodsSemi-structured interviews (n = 22), guided by the COM-B model were conducted with people aged 35–60 years, at risk of or living with CD and not meeting the PA guidelines. A hybrid analytic approach of thematic inductive and deductive analysis was applied to the participant transcripts guided by a COM-B informed coding framework.ResultsIn total, 37 determinants across constructs related to capability, opportunity and motivation were prominent, examples include; physical capability constraints, the conflation of exercise with weight management, credibility of the health services in PA advice, communication styles in PA promotion, expectations of tailored support for PA, social support, accessibility, and integration of PA into routine habits.ConclusionExploring the determinants of PA promotion through the lens of the COM-B model facilitated a systematic approach to understanding the primary care user perspective of the healthcare professional (HCP) broaching the topic of PA. Findings emphasise the value of HCPs being supported to broach the issue of PA in a therapeutic and patient-centred manner using diverse and flexible approaches, while highlighting the importance of tailored, accessible PA opportunities that build self-efficacy and foster social support. The research provides valuable learnings to support PA promotion and the development of strategies in primary care through encompassing the perspective of those living with or at risk of CD.

Association of 24-hour movement guideline adherence, mental health and quality of life in young adults: the role of e-Health literacy.

The spread of Covid-19 and resultant infection prevention strategies have disturbed the life routine of Chinese young adults, led to reduced physical activity (PA), prolonged screen time (ST) and inadequate sleep duration (SP), and made immense influence on their mental health (MH) and quality of life (QoL). E-Health literacy (EHL) can enable citizens to use available online information to respond to the highly complex information environment and make appropriate health decisions. This study aims to examine associations between adhering to 24-h movement (24HM) guidelines and MH and QoL among young adults, as well as to identify any mediating or moderating role of EHL in these associations. 1742 young adults (20.03 ± 1.54 years old, 68.6% females) from north and south China completed self-report measures of 24HM (PA, ST and SP), health indicators (MH and QoL), EHL and demographic information through an online survey between 4 Apr and 16 Jun 2022. Generalized linear mixed models were applied for data analysis. Results showed that adhering to PA, ST and SP guidelines were all positively connected with QoL while MH was associated with adhering ST or SP guidelines. Adhering to more of 24HM guidelines was linked to better MH and QoL. EHL significantly mediated the association of guideline adherence and QoL and moderate that of guideline adherence and MH. This is the first study to investigate the role of EHL on the associations between 24HM and MH as well as QoL during the Covid-19. The findings may contribute to further empirical research or intervention that aims to promote MH or QoL among young adults more effectively or provide valuable references for developing relevant strategies or policy of health promotion or public health events in China.

Examining associations between physical activity context and children meeting daily physical activity guidelines: the role of outdoor play, sports, and other organized activities.

Less than one-quarter of US children meet physical activity (PA) guidelines. Understanding the context in which PA occurs and how these contexts may play a role in meeting PA guidelines is an essential step toward developing effective behavioral interventions. The purpose of this study was to examine associations between PA context (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines in a representative sample of children living in Texas. We analyzed cross-sectional data from a statewide sample of fourth-grade children in Texas who completed the 2019-2020 Texas School Physical Activity and Nutrition (Texas SPAN) survey. The Texas SPAN survey was designed to monitor the statewide prevalence of overweight/obesity among school children and assess habitual self-reported obesity-related behaviors, including diet and PA. Weighted Poisson regression models were employed to examine the associations between PA contexts (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines, adjusting for sex, race/ethnicity, overweight/obesity, urban-rural status, and economic disadvantage. A total of 16.7% of fourth-grade children met physical activity guidelines every day during the week (mean age = 9.4 ± 0.6 years; female = 48.7, 51.8% Hispanic, mean days meeting PA guideline = 3.6 ± 2.3 days). One in ten (11.2%) children did not meet daily PA guidelines on any day of the week, and 72.1% met them between 1 and 6 days. Participating in sports (b = 0.22, 95%CI:0.14, 0.30), any other organized physical activities (b=0.13, 95%CI:0.017, 0.19), and playing outdoors 1-3 days (b = 0.25, 95%CI:0.04, 0.46) and 4-7 days in the past week (b = 0.77, 95%CI:0.57, 0.97) was significantly and positively associated with the number of days children met PA guidelines. Participating in sports, participating in other organized physical activities, and playing outdoors may beneficially influence the number of days children meet PA guidelines. PA programs should consider these contextual factors and investigate how to promote organized activities and outdoor play effectively and appropriately among children.

Time- vs Step-Based Physical Activity Metrics for Health

Current US physical activity (PA) guidelines prescribe moderate to vigorous PA (MVPA) time of at least 150 minutes per week for health. An analogous step-based recommendation has not been issued due to insufficient evidence. To examine the associations of MVPA time and step counts with all-cause mortality and cardiovascular disease (CVD). This cohort study analyzed data from an ongoing follow-up study of surviving participants of the Women's Health Study, a randomized clinical trial conducted from 1992 to 2004 in the US to evaluate use of low-dose aspirin and vitamin E for preventing cancer and CVD. Participants were 62 years or older who were free from CVD and cancer, completed annual questionnaires, and agreed to measure their PA with an accelerometer as part of a 2011-2015 ancillary study. Participants were followed up through December 31, 2022. Time spent in MVPA and step counts, measured with an accelerometer for 7 consecutive days. The associations of MVPA time and step counts with all-cause mortality and CVD (composite of myocardial infarction, stroke, and CVD mortality) adjusted for confounders. Cox proportional hazards regression models, restricted mean survival time differences, and area under the receiver operating characteristic curve (AUC) were used to evaluate the associations. A total of 14 399 women (mean [SD] age, 71.8 [5.6] years) were included. The median (IQR) MVPA time and step counts were 62 (20-149) minutes per week and 5183 (3691-7001) steps per day, respectively. During a median (IQR) follow-up of 9.0 (8.0-9.9) years, the hazard ratios (HR) per SD for all-cause mortality were 0.82 (95% CI, 0.75-0.90) for MVPA time and 0.74 (95% CI, 0.69-0.80) for step counts. Greater MVPA time and step counts (top 3 quartiles vs bottom quartile) were associated with a longer period free from death: 2.22 (95% CI, 1.58-2.85) months and 2.36 (95% CI, 1.73-2.99) months at 9 years follow-up, respectively. The AUCs for all-cause mortality from MVPA time and step counts were similar: 0.55 (95% CI, 0.52-0.57) for both metrics. Similar associations of these 2 metrics with CVD were observed. Results of this study suggest that among females 62 years or older, MVPA time and step counts were qualitatively similar in their associations with all-cause mortality and CVD. Step count-based goals should be considered for future guidelines along with time-based goals, allowing for the accommodation of personal preferences.

“We can do this”: Physical educators’ role breadth self-efficacy to be involved with CSPAPs from an occupational socialization perspective

In the United States, the Comprehensive School Physical Activity Program (CSPAP) is a whole-of-school framework to ensure youth meet physical activity guidelines. Physical education teachers (PETs) are poised to be CSPAP leaders, but implementation is low. PETs’ involvement with CSPAPs may be better understood through the lens of their role breadth self-efficacy, which captures how professionals feel about their ability to undertake expanded workplace roles. Furthermore, investigating PETs’ CSPAP-related role breadth self-efficacy from the perspective of occupational socialization theory could help to identify critical intervention points in PETs’ career development to support CSPAP implementation. The purpose of this study, therefore, was to explore PETs’ perceptions of how the phases of occupational socialization theory influence their role breadth self-efficacy to be involved with CSPAPs. Stratified random sampling and convenience sampling were used to recruit 25 PETs ( n = 16 female) in the United States. Data were collected using individual, semi-structured interviews and analyzed using constant comparison. The findings are represented in three overarching themes, each accompanied by corresponding subthemes: (a) modeling and encouragement from socializing agents, (b) learn by doing: mastery experiences, and (c) agent of change: “I believe in this.” The PETs’ childhood physical activity experiences, physical activity leadership development within teacher education, mentorship from experienced educators who exemplify effective strategies, and the capacity to foster social capital within the workplace are key factors impacting PETs’ CSPAP-related role breadth self-efficacy. Further investigation into mentorship programs for novice PETs to lead CSPAPs and best practices for CSPAP training in teacher education is recommended.

Physical activity and functional social support in community-dwelling older adults: a scoping review

BackgroundGlobally, the population of older people is increasing and is estimated to reach nearly 2.1 billion by 2050. Physical activity (PA) is one of the key components for successful ageing. However, PA decreases with age and many older adults do not meet PA guidelines. Previous research has shown that social support (SOSU) is related to PA in older people. The aim of this scoping review is to identify and map all of the available evidence and to explore the association between functional SOSU and PA in older adults. Functional SOSU consists of emotional, informational, instrumental and companionship SOSU and social comparison.MethodsA scoping review was conducted using the Joanna-Briggs manual. Quantitative and qualitative studies investigating associations between functional SOSU and PA levels in older adults (mean age ≥ 60 years) were identified through a systematic search in seven electronic databases up to August 2023. After removing duplicates, 20,907 articles were screened for titles and abstracts. The results were analysed separately for different types of SOSU.Results116 articles met the inclusion criteria; 72% were quantitative studies and 28% were qualitative studies. Most studies used self-reported PA measures, only 23% of the studies used objective-reported PA measures. Most studies of SOSU for PA reported positive associations but the evidence is inconclusive when the source of support is considered. PA is positively associated with general, emotional, informational, and companionship SOSU, while instrumental support may occasionally be negatively associated. Companionship support is particularly influential on PA, especially in group settings, as it promotes social connectedness. Qualitative studies show that social comparison also supports PA. Different forms of SOSU generally show positive associations with PA.ConclusionsWhile the evidence on the association between functional SOSU and PA is mixed, most studies show that there is a positive association. PA may also be a strategy for improving social contact and social integration. This study offers a comprehensive overview of measures for SOSU and PA and thereby informs future research and policy-making.

Association of physical activity and screen time with cardiovascular disease risk in the Adolescent Brain Cognitive Development Study

BackgroundAccording to the Physical Activity Guidelines Advisory Committee Scientific Report, limited evidence is available on sedentary behaviors (screen time) and their joint associations with physical activity (steps) for cardiovascular health in adolescence. The objective of this study was to identify joint associations of screen time and physical activity categories with cardiovascular disease (CVD) risk factors (blood pressure, hemoglobin A1c, cholesterol) in adolescence.MethodsThis study analyzed data from the Adolescent Brain Cognitive Development (ABCD) Study, comprising a diverse sample of 4,718 U.S. adolescents aged 10–15 years between 2018 and 2021. Steps were measured by a Fitbit wearable device and levels were categorized as low (1,000–6,000), medium (> 6,000–12,000), and high (> 12,000) averaged daily step counts. Self-reported recreational screen time hours per day were classified as low (0–4), medium (> 4–8), and high (> 8) hours per day. CVD risk factors including blood pressure, hemoglobin A1c, and cholesterol (total and HDL) were measured.ResultsThe analytical sample averaged 6.6 h of screen time per day and 9,722 steps per day. In models including both screen time and steps, the high screen time category was associated with a 4.27 higher diastolic blood pressure percentile (95% CI 1.83–6.73) and lower HDL cholesterol (B= -2.85, 95% CI -4.77 to -0.94 mg/dL) compared to the low screen time category. Medium (B = 3.68, 95% CI 1.24–6.11) and low (B = 7.64, 95% CI 4.07–11.20) step categories were associated with higher diastolic blood pressure percentile compared to the high step category. The medium step category was associated with lower HDL cholesterol (B= -1.99, 95% CI -3.80 to -0.19 mg/dL) compared to the high step category. Findings were similar when screen time and step counts were analyzed as continuous variables; higher continuous step count was additionally associated with lower total cholesterol (mg/dL).ConclusionsCombinations of low screen time and high steps were generally associated with favorable cardiovascular health markers including lower diastolic blood pressure and higher HDL cholesterol, which can inform future adolescent health guidelines.

Move for Life an intervention for inactive adults aged 50 years and older: a cluster randomised feasibility trial.

Move for Life (MFL) is a theory-informed intervention that was developed to augment established physical activity (PA) programmes and enable inactive adults aged 50 years and older to be more active. This study examined the feasibility of MFL and sought to provide evidence of its potential for improving PA and associated health outcomes. A 3-arm cluster randomised feasibility trial compared MFL intervention, usual provision (UP) and control (CON) groups at baseline (T0), post-intervention (T1, at 8, 10 or 12- weeks) and 6-month follow up (T2). We used purposive sampling strategies to recruit participants according to characteristics of interest. Feasibility outcomes assessed recruitment, fidelity, adherence, retention and data completion rates based on pre-set criteria. Primary outcomes were accelerometer-based moderate-to-vigorous intensity PA (MVPA) and self-reported compliance with physical activity guidelines (PAGL). Secondary outcomes included light intensity PA (LiPA), standing time, sedentary time, body composition (adiposity), physical function and psychological well-being. We used linear mixed models (continuous outcomes) or generalized estimated equations (categorical outcomes) to estimate group differences over time in the study outcomes. Progression criteria for feasibility outcomes were met, and 733 individuals were recruited. Considering a 6-month period (T0-T2), while self-reported compliance with PAGL increased in MFL relative to UP and CON and in UP relative to CON, standing time decreased in MFL relative to CON and sedentary time increased in the latter compared to UP. Waist circumference decreased in MFL relative to UP and CON. MFL outperformed UP in the Timed Up and Go Test while MFL and UP increased the distance covered in the Six-Minute Walk Test compared to CON. Psychological well-being increased in MFL relative to CON (all p < 0.05). Findings show that MFL is feasible, while data are promising with regards to the potential of improving community PA programmes for adults aged 50 or more years. https://www.isrctn.com/Registration#ISRCTN11235176.

Genetic Liability to Cardiovascular Disease, Physical Activity, and Mortality: Findings from the Finnish Twin Cohort.

We investigated whether longitudinally assessed physical activity (PA) and adherence specifically to World Health Organization PA guidelines mitigate or moderate mortality risk regardless of genetic liability to cardiovascular disease (CVD). We also estimated the causality of the PA-mortality association. The study used the older Finnish Twin Cohort with 4897 participants aged 33 to 60 yr (54.3% women). Genetic liability to coronary heart disease and systolic and diastolic blood pressure was estimated with polygenic risk scores (PRS) derived from the Pan-UK Biobank ( N ≈ 400,000; >1,000,000 genetic variants). Leisure-time PA was assessed with validated and structured questionnaires three times during 1975 to 1990. The main effects of adherence to PA guidelines and the PRS × PA interactions were evaluated with Cox proportional hazards models against all-cause and CVD mortality. A cotwin control design with 180 monozygotic twin pairs discordant for meeting the guidelines was used for causal inference. During the 17.4-yr (mean) follow-up (85,136 person-years), 1195 participants died, with 389 CVD deaths. PRS (per 1 SD increase) were associated with a 17% to 24% higher CVD mortality risk but not with all-cause mortality except for the PRS for diastolic blood pressure. Adherence to PA guidelines did not show significant independent main effects or interactions with all-cause or CVD mortality. Twins whose activity levels adhered to PA guidelines over a 15-yr period did not have statistically significantly reduced mortality risk compared with their less active identical twin sibling. The findings were similar among high, intermediate, and low genetic risk levels for CVD. The genetically informed Finnish Twin Cohort data could not confirm that adherence to PA guidelines either mitigates or moderates genetic CVD risk or causally reduces mortality risk.
