Project description:Youth sport is a key physical activity opportunity for children and adolescents. Several factors influence youth sport participation, including social factors, but this has not to date been clearly delineated. This study is a scoping review to survey the literature on the influence of family and peers on youth sports participation. The review identified 111 articles of which the majority were cross-sectional, included boys and girls, and were conducted primarily in the United States, Canada, Australia, and the United Kingdom. The articles were grouped into 8 research themes: (1) reasons for participation, (2) social norms, (3) achievement goal theory, 4) family structure, (5) sports participation by family members, (6) parental support and barriers, (7) value of friendship, and (8) influence of teammates. Friendships were key to both initiation and maintenance of participation, parents facilitated participation, and children with more active parents were more likely to participate in sport. Less is known on how family structure, sibling participation, extended family, and other theoretical frameworks may influence youth sport. The review suggests that social influences are important factors for ensuring participation, maximizing the quality of the experience, and capitalizing on the benefits of youth sport. Future research studies, programs, and policies promoting and developing evidence-based youth sporting experiences should consider social influences on youth sport participation.

Project description:Previous studies have indicated that both low physical activity and low physical fitness are associated with a higher level of stress but the influence of age and health status on the associations is unknown. This was examined in a cross-sectional study based on data from the Danish Capital Region Health Survey 2017. Among all adults ≥ 16 years residing in the largest of five regions in Denmark 1. January 2017 a random sample of 104,950 was invited to participate. Hereof, 55.185 responded (52,6%). Physical activity during leisure time, fitness, self-rated health and stress (Cohens Perceived Stress Scale) was self-reported by questionnaire. Logistic regression weighted for size of municipality and non-response was used. Age modified the associations. In all age-groups odds ratio (OR) for a high level of stress was increasingly higher the lower the level of physical activity. The association was strongest among the 16-24-year-olds and persisted after adjustment for self-rated health, that otherwise attenuated the associations to an increasing extent the older the age-group. Similar models investigating the modifying effect of age on the association between self-rated fitness and stress showed the same patterns and tendencies. This study showed that physical activity and self-rated fitness were both associated with stress. The OR for a high level of stress was increasingly higher the lower the level of physical activity or self-rated fitness. This was found in all age-groups, but most pronounced among the 16-24-year-olds. Furthermore, findings suggest that health condition explains the associations to an increasing extent with increasing age.

Project description:Mounting evidence indicates a potential beneficial effect of vigorous-intensity physical activity on hepatocellular carcinoma (HCC). However, the association between moderate-intensity physical activity, such as brisk walking, and the risk of HCC remains largely unknown. Two prospective cohorts of 77,535 women from the Nurses' Health Study and 44,540 men from the Health Professionals Follow-up Study were included. Weekly time spent on physical activities were updated biennially. The Cox proportional hazard regression model was used to calculate multivariable hazard ratios (HR) and 95% confidence intervals (95% CI). After an average 23-year follow-up, we identified 138 incident HCC cases. A higher amount of total physical activity was not significantly associated with a reduced risk of HCC (top tertile vs. bottom tertile; HR = 0.78; 95% CI, 0.51-1.18; P trend = 0.33). For the same comparison, there was an inverse association between moderate-intensity activity and HCC risk (HR = 0.60; 95% CI, 0.38-0.94; P trend = 0.04), whereas no statistically significant association with vigorous-intensity activity (HR = 0.88; 95% CI, 0.56-1.37; P trend = 0.74). Engaging in brisk walking was significantly associated with a lower risk of HCC (over 1 hour/week vs. non-brisk walking; HR = 0.50; 95% CI, 0.31-0.78; P trend = 0.006). The association between brisk walking and HCC risk was generally present across all subgroups, including age, body mass index, type 2 diabetes mellitus, smoking status, aspirin use, and alcohol consumption (all P interaction ≥ 0.05). In conclusion, moderate-intensity activity, especially brisk walking, was associated with reduced risk of HCC among U.S. men and women. If confirmed, brisk walking might serve a feasible way for HCC prevention.

Project description:Although best practice recommendations exist regarding school-based healthy eating and physical activity policies, practices, and programs, research indicates that implementation is poor. As the field of implementation science is rapidly evolving, an update of the recent review of strategies to improve the implementation of healthy eating and physical activity interventions in schools published in the Cochrane Library in 2017 was required. The primary aim of this review was to examine the effectiveness of strategies that aim to improve the implementation of school-based policies, practices, or programs to address child diet, physical activity, or obesity. A systematic review of articles published between August 31, 2016 and April 10, 2019 utilizing Cochrane methodology was conducted. In addition to the 22 studies included in the original review, eight further studies were identified as eligible. The 30 studies sought to improve the implementation of healthy eating (n = 16), physical activity (n = 11), or both healthy eating and physical activity (n = 3). The narrative synthesis indicated that effect sizes of strategies to improve implementation were highly variable across studies. For example, among 10 studies reporting the proportion of schools implementing a targeted policy, practice, or program versus a minimal or usual practice control, the median unadjusted effect size was 16.2%, ranging from -0.2% to 66.6%. Findings provide some evidence to support the effectiveness of strategies in enhancing the nutritional quality of foods served at schools, the implementation of canteen policies, and the time scheduled for physical education.

Project description:The inverse association between physical activity and cancer risk may be mediated by higher melatonin levels. However, few studies have examined the effect of increased physical activity on melatonin levels.The parent study was a randomized controlled trial that randomized 51 men and 49 women to a 12-month moderate-to-vigorous aerobic exercise intervention ("exercisers") and 51 men and 51 women to a stretching control ("controls"). Participants were of ages 40 to 75 years, and previously sedentary. Levels of the principal urinary metabolite of melatonin, 6-sulfatoxymelatonin (aMT6s), corrected for creatinine levels, were measured in spot morning urine samples by immunoassay at baseline and 12 months. Changes in levels between exercisers and controls were compared using generalized estimating equations for linear regression.We observed no statistically significant difference in the change in aMT6s levels from baseline to 12 months in exercisers compared with controls (change in aMT6s levels: exercisers, +6.5%; controls, +13%; P = 0.66). There was no evidence of effect modification by age, sex, or body mass index.A 12-month moderate-intensity exercise intervention did not affect levels of aMT6s.Further research needs to focus on other potential mechanisms through which physical activity may reduce the risk of cancer.

Project description:IntroductionPhysical inactivity and female sex are independently associated with increased Alzheimer's disease (AD) lifetime risk. This study investigates the possible interactions between sex and physical activity on neuroimaging biomarkers.MethodsIn 134 cognitively unimpaired older adults (≥65 years, 82 women) from the Age-Well randomized controlled trial (baseline data), we investigated the association between physical activity and multimodal neuroimaging (gray matter volume, glucose metabolism, perfusion, and amyloid burden), and how sex modulates these associations.ResultsThe anterior cingulate cortex volume was independently associated with sex and physical activity. Sex and physical activity interacted on perfusion and amyloid deposition in medial parietal regions, such that physical activity was related to perfusion only in women, and to amyloid burden only in men.DiscussionPhysical activity has both sex-dependent and sex-independent associations with brain integrity. Our findings highlight partly distinct reserve mechanisms in men and women, which might in turn influence their risk of AD.HighlightsSex and physical activity have been linked to Alzheimer's disease (AD) progression.The association of sex and physical activity with brain health is partly independent.Different reserve mechanisms exist in men and women.

Project description:Empirical evidence supports an inverse relationship between physical activity (PA) and adiposity, but studies using detailed measures of both are scarce. The relationship between regional adiposity and accelerometer-derived PA in men and women are described.Cross-sectional analysis included 253 participants from a weight loss study limited to ages 20-45 years and BMI 25-39.9 kg m(-2) . PA data were collected with accelerometers and expressed as total accelerometer counts and average amount of time per day accumulated in different intensity levels [sedentary, light-, and moderate-to-vigorous intensity PA (MVPA)]. Accumulation of time spent above 100 counts was expressed as total active time. Computed tomography (CT) was used to measure abdominal and adipose tissue (AT). Multivariate linear regression analyses were used to assess the relationship between regional adiposity (dependent variable) and the various PA levels (independent variable), and were executed separately for men and women, adjusting for wear time, age, race, education, and BMI.Among males, light activity was inversely associated with total AT (? = -0.19; P = 0.02) as well as visceral AT (VAT) (? = -0.30; P = 0.03). Among females sedentary time was positively associated with VAT (? = 0.11; P = 0.04) and total active time was inversely associated with VAT (? = -0.12; P = 0.04).Findings from this study suggest that PA intensity level may influence regional adiposity differently in men and women. Additional research is needed in larger samples to clarify the difference in these associations by sex, create recommendations for the frequency, duration and intensity of PA needed to target fat deposits, and determine if these recommendations should differ by sex.

Project description:ObjectiveTo understand osteoporosis screening practices, particularly in men, by a diverse cohort of physicians, including primary care physicians, endocrinologists, and geriatricians.MethodsWe surveyed randomly selected members of the American Academy of Family Practice, Endocrine Society, and American Geriatrics Society. Respondents were asked to rate how often they would screen for osteoporosis in four different clinical scenarios by ordering a bone density scan. Multivariable logistic regression analyses were conducted to determine factors associated with offering osteoporosis screening in men in each clinical scenario. Physicians were also asked to note factors that would lead to osteoporosis screening in men.ResultsResponse rate was 63% (359/566). While 90% respondents reported that they would always or frequently screen for osteoporosis in a 65-year-old post-menopausal woman, only 22% reported they would screen a 74-year-old man with no significant past medical history. Endocrinologists were more likely to screen a 74-year-old man compared to primary care physicians (odds ratio, 2.32; 95% confidence interval, 1.10 to 4.88). In addition to chronic steroid use (94%), history of nontraumatic fractures (88%), and androgen-deprivation therapy for prostate cancer (82%), more than half the physicians reported suppressive doses of thyroid hormone (64%) and history of falls (52%) as factors leading to screening for osteoporosis in men.ConclusionsOur survey results highlight heterogeneity in osteoporosis screening in men, with underscreening in some scenarios compared to women, and identify factors that lead to screening in men. These findings can help design interventions to improve osteoporosis screening in men.

Project description:The home environment has a significant influence on children's physical activity and obesity risk. Our understanding of this environment is limited by current measurement tools. The Home Self-administered Tool for Environmental assessment of Activity and Diet addresses this gap. This paper describes the development and psychometric testing of its family physical activity and screen media practices and beliefs survey.MethodsSurvey development was guided by the Analysis Grid for Environments Linked to Obesity (ANGELO) framework and informed by a literature review, expert opinion, and cognitive interviews. Parents of children ages 3-12 years (n = 129) completed the HomeSTEAD survey three times over 12-18 days. Additionally, parents reported on child behaviors and trained staff measured parent and child height and weight. Five exploratory factor analyses were conducted after categorizing items into: control of physical activity, control of screen media, explicit modeling, implicit modeling, and perceived barriers and facilitators. Scales with 3 or more items underwent scale reduction. Psychometric testing evaluated internal consistency (Chronbach's alphas), test-retest reliability (analysis of variance and intraclass correlations (ICC)), and construct validity (correlations with child BMI, physical activity, screen time). An integrated conceptual model of parent physical activity and screen media practices and beliefs was developed based on recent literature to aid in the identification and naming of constructs.ResultsFinal scales demonstrated good internal consistency (median Cronbach's alpha = 0.81, IQR = 0.74-0.85), test-retest reliability (median ICC = 0.70, IQR = 0.66-0.78), and construct validity (with correlations between scale score and children's behaviors generally in the expected direction). Comparison with the integrated conceptual model showed that most identified constructs were captured.ConclusionsThe family physical activity and screen media practices survey advances the measurement of the home environment related to children's physical activity, screen time, and weight. The integrated conceptual model provides a useful framework for researchers studying both physical activity and screen media parenting practices.

Project description:BackgroundDuring the past decade, guidelines for youth aerobic and muscle-strengthening physical activity remained unchanged. Active People, Healthy NationSM highlighted school and youth strategies (eg, sports and physical education [PE]) to increase physical activity. Sex, grade, and race/ethnicity disparities exist. This study examines sex-specific trends and differences by grade and race/ethnicity for the prevalence of 5 youth physical activity behaviors from 2009 to 2019.MethodsThe national Youth Risk Behavior Survey assesses adolescents (grades 9-12) meeting the aerobic, muscle-strengthening, and both guidelines (2011-2019) and sports participation and daily PE (2009-2019). Sex-stratified logistic regression assessed trends and 2009 or 2011-2019 differences by grade and racial/ethnic subgroups.ResultsDecreases in meeting the aerobic, muscle-strengthening, and both guidelines were observed for nearly all male subgroups by grade and race/ethnicity, whereas female subgroups exhibited declines or no change to low prevalence. Sports and PE participation remained mostly constant; select subgroups showed decreases (ie, Hispanic males [sports]; Black males and ninth-grade females [PE]).ConclusionsPast decade prevalence and patterns suggest that school-based and other strategies for all adolescents and tailored interventions for sex-specific subgroups may be needed to supplement sports and PE in promoting high school youth physical activity.
