This paper used a nationally representative sample of children from the United States to examine the extent to which physical activity and sports participation may promote growth in children's executive functions (EFs), attention, and social self‐control over time. Using data from the ECLS‐K:2011 (N = 18,174), findings indicated that regular physical activity predicted growth in EFs and attention from 3rd to 4th grade (βs = 0.03–0.05) but not from kindergarten to 1st grade. After controlling for the frequency of physical activity, participation in group sports predicted increases in EFs, attention, and social self‐control during both periods (βs = 0.02–0.04). Though modest in size, the findings suggest that encouraging children to engage in more frequent and more team‐based activity will benefit the development of their EFs and related skills, and especially so for children in middle childhood.

Aims and objectives: To identify the current state of knowledge about the use of the sit‐to‐stand intervention with older people and to identify implications for further research. Background: Many older people experience mobility challenges which can negatively affect their well‐being. Physical activities are vital to improving or maintaining mobility. Although there is evidence that mobility challenged older people benefit from the sit‐to‐stand intervention, there is a need to systematically examine the state of knowledge about this intervention. Design: Scoping review using Arksey and O'Malley's methodological framework. Methods: A systematic search of three databases was completed. Abstracts were evaluated for relevance using predetermined inclusion criteria. Studies that met the inclusion criteria had data extracted and were appraised for internal and external validity. Narrative synthesis was based on methods described by Popay and colleagues. Results: Of 3,041 papers, six studies met the inclusion criteria. Publications provided a range of sit‐to‐stand interventions with durations varying from four weeks to six months. The frequency of each intervention fluctuated from three to seven times/week with a duration of 15–45 min. Different professionals prompted the activity. Three themes were identified the following: (a) sit‐to‐stand activity as an intervention; (b) generalisability of findings; and (c) sustainability. Conclusions: Most of the studies reviewed indicated improvements in performance of the sit‐to‐stand activity and in motor function. However, issues with studies rigour do not allow us to make generalisations. Further research is needed to confirm the effectiveness of the intervention. Implications for practice: Healthcare providers are expected to offer evidence‐based patient care. This review details current knowledge about the sit‐to‐stand intervention with older people.

People with end-stage kidney disease (ESKD) receiving peritoneal dialysis (PD) are physically inactive leading to low physical function and poor health outcomes. Guidelines recommend that nephrologists encourage PD patients to increase their activity levels; however, PD patients are often discouraged from participating in exercise programs because of perceived barriers and a lack of precision about the appropriate exercise regimen. This review suggests ways forward to assist nephrology professionals to encourage PD patients to exercise, instead of creating barriers. The paper draws on the literature in addition to the experience of programs in France, the United States, and Australia to demonstrate the possibilities when considering increasing physical activity in this group.

To quantify physical activity (PA) levels in people with multiple sclerosis (pwMS) using objective measurement and to establish using a meta‐analytical approach if pwMS are less active than the general population. A systematic search of eight databases was conducted. Cohort and intervention studies which included an objective measure of PA were included. Objective PA outputs of steps per day and minutes of moderate‐vigorous activity (MVPA) per day were extracted from the MS studies and the published NHANES dataset. Meta‐analysis was used to compare the differences between the groups for these parametric outcomes. A general population sample from the National Health and Nutritional Examination Survey (NHANES) in the United States of America was used as a comparative group. The systematic search resulted in 32 papers (n = 2 randomized control trials, n = 30 cohort studies). A total of 3 762 pwMS were included. The sample was largely female (n = 3 118, 82.8%) and ambulatory with/without use of an aid (n = 31 studies). There were significant differences between the MS and the published NHANES comparative group with respect to 1) steps per day [mean difference: −3845 (−4120.17, −3569.83), P < .0001, n = 10 studies] and 2) minutes of MVPA per day [mean difference: 9.00 (−12.5, −5.4), P < .0001, n = 3 studies], indicating pwMS are less physically active than the NHANES sample. Results suggest that pwMS are less physically active than a general population across PA outputs of steps per day and minutes of MVPA per day. There is a need to increase PA levels among pwMS.

This paper examined the psychosocial predictors of weight loss among race and sex subgroups. Analyses included overweight and obese participants from the PREMIER study, a previously published randomized trial that examined the effects of two multi-component lifestyle interventions on blood pressure among pre-hypertensive and stage 1 hypertensive adults. Both intervention conditions received behavioural recommendations for weight loss and group sessions. Weight and psychosocial measures of self-efficacy and social support for diet and exercise were assessed at baseline and at 6 months. There were 157 African-American (AA) women, 46 AA men, 203 non-AA women and 182 non-AA men with an average age of 50 years and average body mass index of 34 at baseline. Multiple predictor regression models were performed individually by race and sex subgroup. Among AA women, increases in diet self-efficacy were associated with weight loss. Among AA men, increases in diet-related social support and self-efficacy, along with increases in family support to exercise, were associated with weight loss (all Ps <0.05). Among non-AA women, increases in friends' support to exercise and exercise-related self-efficacy were associated with weight loss, and among non-AA men only increases in diet self-efficacy were associated with weight loss (all Ps <0.05). These results emphasize the need for targeted interventions based on race and sex to optimize the impact of lifestyle-based weight loss programmes., (© 2015 World Obesity.)

Influenza and Other Respiratory Viruses DOI: 10.1111/irv.12019. Background Findings from studies examining the association between obesity and acute respiratory infection are inconsistent. Few studies have assessed the relationship between obesity-related behavioral factors, such as diet and exercise, and risk of acute respiratory infection. Objective To determine whether community prevalence of obesity, low fruit/vegetable consumption, and physical inactivity are associated with influenza-related hospitalization rates. Methods Using data from 274 US counties, from 2002 to 2008, we regressed county influenza-related hospitalization rates on county prevalence of obesity (BMI ≥ 30), low fruit/vegetable consumption (<5 servings/day), and physical inactivity (<30 minutes/month recreational exercise), while adjusting for community-level confounders such as insurance coverage and the number of primary care physicians per 100 000 population. Results A 5% increase in obesity prevalence was associated with a 12% increase in influenza-related hospitalization rates [adjusted rate ratio (ARR) 1·12, 95% confidence interval (CI) 1·07, 1·17]. Similarly, a 5% increase in the prevalence of low fruit/vegetable consumption and physical inactivity was associated with an increase of 12% (ARR 1·12, 95% CI 1·08, 1·17) and 11% (ARR 1·11, 95% CI 1·07, 1·16), respectively. When all three variables were included in the same model, a 5% increase in prevalence of obesity, low fruit/vegetable consumption, and physical inactivity was associated with 6%, 8%, and 7% increases in influenza-related hospitalization rates, respectively. Conclusions Communities with a greater prevalence of obesity were more likely to have high influenza-related hospitalization rates. Similarly, less physically active populations, with lower fruit/vegetable consumption, tended to have higher influenza-related hospitalization rates, even after accounting for obesity.

Childhood overweight has risen dramatically & the United States during the past three decades. The search for policy solutions is limited by a lack of evidence regarding the effectiveness of state policies for increasing physical activity among youths. This paper estimates the correlation of student physical activity with a variety of state policies. We study nationwide data on high school students from the Youth Risk Behavior Surveillance System for 1999, 2001, and 2003 merged with data on state policies from several sources. We control for a variety of characteristics of states and students to mitigate bias due to the endogenous selection of policies, but we conservatively interpret our results as correlations, not causal impacts. Two policies are positively correlated with participation in physical education (PE) class for both boys and girls: a binding PE unit requirement and a state PE curriculum. We also find that state spending on parks and recreation is positively correlated with two measures of girls' overall physical activity. [ABSTRACT FROM AUTHOR]

Objectives: Using photographs of human remains, including bones and teeth, in publications may have unethical implications when considering descendant communities. In the United States, many museums in deference to agreement with descendent communities prohibit publication of photos. In order to convey specific information to audiences and respect the wishes of descendent communities, authors should turn to digital illustrations, where appropriate. This article seeks to demonstrate that, regardless of skill or experience with digital illustration software, this technique is accessible to all researchers. Materials and Methods: Forty participants completed a tutorial on digitizing a mandibular molar with wear and caries. Each participant was provided the same base image and instructions. Participants had various levels of experience with (1) human remains, (2) dentition, and (3) digital illustration software. All participants used the opensource freeware program, Krita. Results: A majority of participants (75%) took 30 to 90 min to complete the exercise; 25 illustrations were produced and showed strong similarities in occlusal outline, occlusal fissures, and dentine exposure. There was a 3.56% (± 0.93%) discrepancy in total tooth outline between participants' outlines (n = 23) and the author's reference image. The average participant satisfaction with their final image was 3.73 (out of 5), and the average user‐friendly rating was 4.2 (out of 5). Discussion: The consistency of illustrations across participants, as well as the satisfactory self‐ratings, demonstrates that digital illustrations, regardless of experience with illustration programs, are accessible to researchers. As a result, more authors should consider replacing photographs of human remains with digital illustrations in publications. While this technique can, and should, be used across any population, the implementation may be one step along a path of a more inclusive anthropology. [ABSTRACT FROM AUTHOR]

Objective: Post‐traumatic stress disorder (PTSD) is common in Veterans. Symptoms can perpetuate into late life, negatively impacting physical and mental health. Exercise and social support are beneficial in treating anxiety disorders such as PTSD in the general population, although less is known about the impact on Veterans who have lived with PTSD for decades. This study assessed associations between social connectedness, physical function and self‐reported change in PTSD symptoms among older Veterans specifically participating in Gerofit. Design Prospective clinical intervention. Setting: Twelve sites of Veterans Affairs (VA) Gerofit exercise program across the United States. Participants: Three hundred and twenty one older Veteran Gerofit participants (mean age = 74) completed physical assessments and questionnaires regarding physical and emotional symptoms and their experience. Measurements Measures of physical function, including 30‐second chair stands, 10‐m and 6‐min walk were assessed at baseline and 3 months; change in PTSD symptoms based on the Diagnostic Statistical Manual—5 (DSM‐5) assessed by a self‐report questionnaire; and social connection measured by the Relatedness Subscale of the Psychological Need Satisfaction in Exercise scale (PNSE) were evaluated after 3 months of participation in Gerofit. Results: Ninety five (29.6%) Veterans reported PTSD. Significant improvement was noted in self‐rated PTSD symptoms at 3 months (P <.05). Moderate correlation (r =.44) was found between social connectedness with other participants in Gerofit and PTSD symptom improvement for those Veterans who endorsed improvement (n = 59). All participants improved on measures of physical function. In Veterans who endorsed PTSD there were no significant associations between physical function improvement and PTSD symptoms. Conclusion: Veterans with PTSD that participated in Gerofit group exercise reported symptom improvement, and social connectedness was significantly associated with this improvement. In addition to physical health benefits, the social context of Gerofit may offer a potential resource for improving PTSD symptoms in older Veterans that warrants further study.

Objective: Both aerobic physical activity and muscle-strengthening exercise are recommended for obesity prevention. However, at the population level, the independent and/or combined associations of these physical activity modalities with obesity are unknown. The aim of this study was to examine the associations between aerobic physical activity and muscle-strengthening exercise with obesity among a representative sample of adults.Methods: Data were pooled from four US public health surveillance surveys from 2011 to 2017. Cross-sectional associations between adherence to the aerobic physical activity (≥ 150 min/wk) and muscle-strengthening exercise (≥ 2 times/wk) guidelines with different classes of BMI-defined obesity were examined using Poisson regression. Prevalence ratios are reported as both unadjusted and adjusted for sociodemographic and lifestyle characteristics.Results: Data were available for 1,677,108 adults (≥ 18 years old). Compared with meeting neither guideline (reference category), meeting both guidelines was associated with the lowest adjusted prevalence ratios (APRs) for the following: Class I obesity and above (BMI ≥ 30.0 kg/m2 ), APR = 0.54 (95% CI: 0.53-0.54); Class II obesity and above (BMI ≥ 35.0 kg/m2 ), APR = 0.32 (95% CI: 0.31-0.33); and Class III obesity and above (BMI ≥ 40.0 kg/m2 ), APR = 0.21 (95% CI: 0.20-0.21).Conclusions: Among nearly 1.7 million US adults, meeting both aerobic and muscle-strengthening exercise guidelines was associated with a lower obesity prevalence, and associations were more pronounced for higher obesity classes.

Objective: To determine adolescent predictors of muscularity‐oriented disordered eating behaviors in young men and women using a nationally representative longitudinal sample in the United States and to examine differences by sex. Method: We used nationally representative longitudinal cohort data collected from baseline (11–18 years old, 1994–1995) and 7‐year follow‐up (18–24 years old, 2001–2002) of the National Longitudinal Study of Adolescent to Adult Health. We examined adolescent demographic, behavioral, and mental health predictors of young adult muscularity‐oriented disordered eating behaviors defined as eating more or differently to gain weight or bulk up, supplements to gain weight or bulk up, or androgenic anabolic steroid use at 7‐year follow‐up. Results: Of the 14,891 included participants, 22% of males and 5% of females reported any muscularity‐oriented disordered eating behavior at follow‐up in young adulthood. Factors recorded at adolescence that were prospectively associated with higher odds of muscularity‐oriented disordered eating in both sexes included black race, exercising to gain weight, self‐perception of being underweight, and lower body mass index z‐score. In addition, participation in weightlifting; roller‐blading, roller‐skating, skate‐boarding, or bicycling; and alcohol among males and depressive symptoms among females during adolescence were associated with higher odds of muscularity‐oriented disordered eating in young adulthood. Conclusions: Interventions to prevent muscularity‐oriented disordered eating behaviors may target at‐risk youth, particularly those of black race or who engage in exercise to gain weight. Future research should examine longitudinal health outcomes associated with muscularity‐oriented disordered eating behaviors. [ABSTRACT FROM AUTHOR]

Objective: To examine the cost-effectiveness of a community-based Diabetes Prevention Program (DPP) for Medicaid beneficiaries from the perspective of the health care sector.Data Sources/study Setting: A total of 847 Medicaid enrollees at high risk for type 2 diabetes participating in a community-based DPP.Study Design: Pre- and post clinical outcome and cost data were used as inputs into a validated diabetes simulation model. The model was used to evaluate quality-adjusted life years (QALYs) and health care costs over a 40-year time horizon from the perspective of the health care sector.Data Collection/extraction Methods: Clinical outcome and cost data were derived from a study examining the effect of financial incentives on weight loss.Principal Findings: Study participants lost an average of 4.2 lb (p < .001) and increased high-density lipoprotein cholesterol by 1.75 mg/dl (p = .002). Intervention costs, which included financial incentives for participation and weight loss, were $915 per participant. The incremental cost-effectiveness ratio was estimated to be $14,011 per QALY but was sensitive to the time horizon studied.Conclusions: Widespread adoption of community-based DPP has the potential to reduce diabetes and cardiovascular-related morbidity and mortality for low-income persons at high risk for diabetes and may be a cost-effective investment for Medicaid programs.

Summary: Background: No study has examined how the pattern of income dynamics influences both of children's body mass index (BMI) trajectory and health behaviours. Objectives: To examine the association between household poverty dynamics and childhood overweight risk in the USA. Methods: Using the longitudinal data of 16 800 children (from kindergarten to the 8th grade) in the nationally representative US cohort‐Early Childhood Longitudinal Study, Kindergarten Class 1998–1999, we examined the differences in BMI trajectory, weight‐related health behaviours and risk of overweight in association with household poverty dynamics during follow‐up (never [no experience of poverty], transient [once], recurrent [≥2 times] and persistent poor [remained]) using mixed models with fractional polynomial functions and estimating equation models. Results: Overall, children experiencing poverty were more likely to have adverse BMI growth trajectory and eating and sedentary behaviours compared with the never poor. The recurrently poor children (12.8%) had the fastest BMI trajectory, highest overweight/obesity prevalence from 5 to 16 years old and highest proportion of excessive soda/fast food consumption and irregular exercise at 8th grade than did others (p < 0.05). The persistently poor (8.4%) were the lowest in BMI growth trajectory but became the second highest in childhood obesity through a steady increase in BMI over time. Children in the recurrently poor group had a 1.5 times (95% CI = 1.0–2.2) higher risk of overweight than those having never experienced poverty during follow‐up. Conclusions: The experience of recurrent household poverty had a significant association with children's adverse eating behaviours and increased obesity risk subsequently. [ABSTRACT FROM AUTHOR]

Abstract: Objective: The need to consider gender when studying exercise in eating disorder (ED) has been underscored. The study aimed to test the psychometric properties and factor structure of the exercise and eating disorder (EED) questionnaire for males with and without ED, to highlight gender differences, and to explore issues relevant for a male version of the EED questionnaire. Method: This cross sectional study included 258 male participants: 55 ED patients (inpatients and outpatients) and 203 student controls. The patient group consisted of 54.5% (n = 30) with AN, 18.2% (n = 10) with BN, 27.2% (n = 15) with unspecified ED. The ED sample was treated as transdiagnostic in all analyses. t Tests, chi‐square test, correlations analyses, and a principal component analysis were conducted. Results: The analyses confirmed that the EED questionnaire had adequate psychometric properties, and a four‐factor solution: (a) compulsive exercise, (b) positive and healthy exercise, (c) awareness of bodily signals, and (d) weight and shape exercise. The questionnaire discriminated significantly (p < .01– < .001) between patients and controls on the global score, subscales, and 16 out of 18 individual items. Convergent validity was demonstrated by high correlations between the EED questionnaire and the eating disorder examination questionnaire (r = .65). Discussion: The results indicated that the EED questionnaire is a valid and reliable tool for males. It is a clinically derived, self‐report questionnaire to assess compulsive exercise among ED patients, regarding attitudes and thoughts toward compulsive exercise and identification of treatment targets and priorities [ABSTRACT FROM AUTHOR]

Exercise is an important part of a healthy lifestyle and influences a variety of health outcomes. Regions vary in their levels of exercise due to geography, climate, culture, and policy. The extent to which a country's policies are consistent with economic freedom has been found to be positively associated with greater participation in physical activity. We empirically investigate the relationship between economic freedom and exercise across U.S. states. Contrary to the cross‐country results, we find that states with higher levels of economic freedom have lower rates of participation in exercise. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to examine the relationships of Cardiometabolic Disease Staging (CMDS), a validated five-stage system for assessing risk for diabetes, cardiovascular mortality, and all-cause mortality, with measures of individual engagement and health-related quality of life (HRQOL) in the US adult population.Methods: Data from the 2011-2014 National Health and Nutrition Examination Survey were used to derive the CMDS stages, five participant engagement measures, and four HRQOL measures among adult participants ≥ 40 years of age. Analyses accounted for the complex sampling design and sample weights.Results: Higher CMDS was associated with greater participant awareness of cardiometabolic risk, but after adjusting for covariates, only Stage 4 remained significant (odds ratio: 5.08; 95% CI: 3.25, 7.94). Higher CMDS was associated with receiving recommendations to engage in a healthy lifestyle, not meeting 2008 physical activity guidelines, and fewer leisure time moderate activities after controlling for covariates. For HRQOL measures, Stage 4 was associated with a higher likelihood of perceiving health as fair or poor (odds ratio: 4.85; 95% CI: 2.42, 9.73).Conclusions: Higher CMDS was associated with greater individual awareness of risk, less leisure time physical activity, and worse self-rated health. CMDS is a clinically practical method for identifying individuals for targeted preventive strategies. [ABSTRACT FROM AUTHOR]

Background: Prospective cohort studies contribute importantly to understanding the role of lifestyle, genetic, and other factors in chronic disease etiology.Methods: The American Cancer Society (ACS) recruited a new prospective cohort study, Cancer Prevention Study 3 (CPS-3), between 2006 and 2013 from 35 states and Puerto Rico. Enrollment took place primarily at ACS community events and at community enrollment "drives." At enrollment sites, participants completed a brief survey that included an informed consent, identifying information necessary for follow-up, and key exposure information. They also provided a waist measure and a nonfasting blood sample. Most participants also completed a more comprehensive baseline survey at home that included extensive medical, lifestyle, and other information. Participants will be followed for incident cancers through linkage with state cancer registries and for cause-specific mortality through linkage with the National Death Index.Results: In total, 303,682 participants were enrolled. Of these, 254,650 completed the baseline survey and are considered "fully" enrolled; they will be sent repeat surveys periodically for at least the next 20 years to update exposure information. The remaining participants (n = 49,032) will not be asked to update exposure information but will be followed for outcomes. Twenty-three percent of participants were men, 17.3% reported a race or ethnicity other than "white," and the median age at enrollment was 47 years.Conclusions: CPS-3 will be a valuable resource for studies of cancer and other outcomes because of its size; its diversity with respect to age, ethnicity, and geography; and the availability of blood samples and detailed questionnaire information collected over time.

Objectives To determine effects of Sit 'N' Fit Chair Yoga, compared to a Health Education program ( HEP), on pain and physical function in older adults with lower extremity osteoarthritis ( OA) who could not participate in standing exercise. Design Two-arm randomized controlled trial. Setting One HUD senior housing facility and one day senior center in south Florida. Participants Community-dwelling older adults (N = 131) were randomly assigned to chair yoga (n = 66) or HEP (n = 65). Thirteen dropped after assignment but prior to the intervention; six dropped during the intervention; 106 of 112 completed at least 12 of 16 sessions (95% retention rate). Interventions Participants attended either chair yoga or HEP. Both interventions consisted of twice-weekly 45-minute sessions for 8 weeks. Measurements Primary: pain, pain interference; secondary: balance, gait speed, fatigue, functional ability measured at baseline, after 4 weeks of intervention, at the end of the 8-week intervention, and post-intervention (1 and 3 months). Results The chair yoga group showed greater reduction in pain interference during the intervention ( P = .01), sustained through 3 months ( P = .022). WOMAC pain ( P = .048), gait speed ( P = .024), and fatigue ( P = .037 ) were improved in the yoga group during the intervention ( P = .048) but improvements were not sustained post intervention. Chair yoga had no effect on balance. Conclusion An 8-week chair yoga program was associated with reduction in pain, pain interference, and fatigue, and improvement in gait speed, but only the effects on pain interference were sustained 3 months post intervention. Chair yoga should be further explored as a nonpharmacologic intervention for older people with OA in the lower extremities. Trial Registration: ClinicalTrials.gov: NCT02113410.

Background and Objectives: Rates of medical illnesses may be higher among individuals with substance use disorders, complicating their care. This study aimed to expand the understanding of other medical conditions in treatment-seeking adults with stimulant use disorder (SUD) using data from Stimulant Reduction Intervention using Dose Exercise (STRIDE), a randomized, multisite trial investigating exercise augmentation of treatment as usual.Methods: Utilizing STRIDE baseline data, we examined demographic and clinical characteristics based on the number of self-reported diagnosed medical conditions among participants meeting eligibility criteria (passing medical screening exam and maximal exercise test, non-opioid dependent, no concomitant beta blocker, or opioid replacement therapy).Results: The majority (59%) of study participants (N = 302, mean age all participants = 39 years) did not report any history of other medical problems. Those with two or more conditions were older (mean age 46 years), reported more pain and worse physical functioning, and more psychiatric disorders (average 1.44). Hypertension was more common among participants with cocaine use disorders only (present in 16%) and liver disease was more common in those with cocaine plus other stimulant use disorders (present in 7%).Conclusion and Scientific Significance: In this sample, patients with SUD were in surprisingly good health. A subpopulation had an overall higher burden of illness with worsened physical and psychiatric functioning. Provision of coordinated care may optimize treatment outcomes for patients based on medical comorbidity burden as well as type of drug abused, although these conclusions should be considered preliminary as they are based on self-reported data.

BACKGROUND: A US federal mandate that school districts devise and implement local wellness policies (LWPs) has potential widespread impact on the nutritional content of foods and beverages available in schools and on the amount of physical activity that students engage in; however, evidence concerning the mandate’s effectiveness is limited. This study describes the content of LWPs of 6 US school districts and steps taken toward their implementation and evaluation. METHODS: During visits to 6 school districts, we interviewed 88 school and community representatives about the content of their district’s LWPs and how the LWPs were being implemented and evaluated. RESULTS: The 6 LWPs were consistent with the federal mandate, although they varied in content and degree of specificity, and none had been fully implemented. All 6 districts were pursuing strategies to ensure that foods and beverages available at school met nutrition standards but did not offer nutrition education to all K-12 students. All 6 districts offered students only limited opportunities for physical activity, and all 6 collected data to monitor process and outcomes of their LWPs. CONCLUSIONS: Partial implementation of LWPs in the districts we visited resulted in significant improvement in the nutritional quality of foods available at district schools, but only slight improvement in students’ opportunities for school-based physical activity. We provide recommendations for school districts on implementation and evaluation. Future research is needed to determine the impact of these LWPs on students’ health. [ABSTRACT FROM AUTHOR]

To investigate relationships between body mass index (BMI), personality type, weight loss regimens, and successful or unsuccessful weight loss. Seven hundred and twenty-one registered nurses (RNs) were recruited from the American Academy of Nurse Practitioners, the membership of a nursing honor society, and RNs at a large state university. Participants completed the Myers-Briggs Type Indicator (MBTI), a demographic survey (age, gender, height, weight, ethnicity, education status, disability, shift work hours, and prescription medication use), and questions related to their weight status, weight loss attempts, and motivation. RNs who had a lower BMI were more successful in losing weight than RNs who had a higher BMI. They were also more successful in their weight loss attempts if they did not use a diet regimen. RNs who were successful in losing weight did not use a specified dietary regimen. [ABSTRACT FROM AUTHOR]

BACKGROUND: Recess is at the heart of a vigorous debate over the role of schools in promoting optimal child development and well-being. Reallocating time to accentuate academic concerns is a growing trend and has put recess at risk. Conversely, pressure to increase activity in school has come from efforts to combat childhood obesity. The purpose of this review was to examine the value of recess as an integral component of the school day. METHODS: A comprehensive review of recess-specific literature was conducted, beginning with a Google Scholar search, to cull definitions, position statements, and policy recommendations from national/international associations and organizations. A multi-database search followed. Additional articles were selected from reference lists. RESULTS: The search yielded a range of articles, from those focused on specific aspects of recess to those that examined multiple factors, including how to structure and conduct recess. Several themes emerged supporting recess as beneficial for children's cognitive, social, emotional, and physical functioning. Optimal recess was well-supervised and safe. Crucial components were well-maintained playground equipment and well-trained supervisors. CONCLUSION: Recess serves a critical role in school as a necessary break from the rigors of academic challenges. Recess is a complement to, not a replacement for, physical education. Both promote activity and a healthy lifestyle; however, recess-particularly unstructured recess and free play-provides a unique contribution to a child's creative, social, and emotional development. From the perspective of children's health and well-being, recess time should be considered a child's personal time and should not be withheld for academic or punitive reasons. [ABSTRACT FROM AUTHOR]

BACKGROUND: School wellness policies are a key component to the prevention of adolescent obesity. This national research study sought to understand the wellness environment in school districts across the country and to identify challenges districts face and needs they have in order to effectively implement, monitor, and evaluate school wellness policies. The study determined (1) perceptions, barriers, and opportunities regarding the development, implementation, and monitoring/evaluation of school wellness policies among school board members, state school boards association leaders, state public health nutrition directors, and school wellness advocates; (2) the readiness and capacity of survey groups to address nutrition and physical activity policies; (3) the extent to which survey groups collaborate; and (4) the acceptability of wellness tools. METHODS: In 2006, over 2900 individuals participated in online surveys, focus groups, and key informant interviews. School board members represented 1296 school districts across the nation. RESULTS: School board members expressed the highest level of confidence among all survey groups that their district has the capacity to develop, implement, and monitor/ evaluate the wellness policy. The disparities among groups are most notable with regard to perceptions of district capacity to monitor/evaluate the policy. School board members are interested in school wellness policy tools and trainings. CONCLUSIONS: There is an opportunity for state school boards associations, state public health nutrition directors, and school wellness advocates to build their own capacity to provide training and resources to districts on wellness issues, particularly physical education/activity, school-based wellness initiatives, and strategies for implementing and monitoring/evaluating wellness policies.

This article reports a cross-national study of developmental change in health-enhancing behavior—healthy eating and regular exercise—among adolescents in China and the United States. The application of a conceptual framework comprising psychosocial and behavioral protective and risk factors—both proximal and distal and at both the individual and social contextual level—is shown to provide a substantial account of variation in change in those behaviors over a 2-year interval. The explanatory account has generality across gender, the 3 grade cohorts, and most importantly, across the 2 markedly diverse societies. [ABSTRACT FROM AUTHOR]

The article focuses on the relationship between physical exercise and depression. The U.S. Department of Health and Human Services has recommended all Americans to engage in 2.5 hours of moderate aerobic physical activity and 1.25 hours of vigorous aerobic physical activity per week. A 2006 study shows that inactive subjects tend to be more depressed than active people. It adds that exercise is still not considered as a first-line or second-line treatment for major depressive disorder (MDD) in the U.S.

The member countries of the World Health Organization have endorsed its Global Strategy on Diet, Physical Activity, and Health. We assess the potential consumption impacts of these norms in the United States, France, and the United Kingdom using a mathematical programming approach. We find that adherence would involve large reductions in the consumption of fats and oils accompanying large rises in the consumption of fruits, vegetables, and cereal. Further, in the United Kingdom and the United States, but not France, sugar intakes would have to shrink considerably. Focusing on sub-populations within each country, we find that the least educated, not necessarily the poorest, would have to bear the highest burden of adjustment. [ABSTRACT FROM AUTHOR]

The article presents the research which dealt with the association of resistin polymorphisms with muscle, bone and fat phenotypes in U.S. men and women. Researchers mention that the polymorphisms in the human resistin gene were associates with physiologically different phenotypes. They also state that the novelty of the associations and the strong genetic effects observed warrant further investigation.

This literature review describes the physical activity behavior of adults with mental retardation consistent with the U.S. Surgeon General's recommendation of 30 minutes of moderate intensity physical activity on 5 or more days per week. The proportion of participants achieving this criterion ranges from 17.5 to 33%. These data are likely to be generous estimates of activity as individuals included in physical activity studies to date have been relatively young and healthy volunteers with mild to moderate limitations. Major sources of physical activity were walking and cycling for transport, chores and work, dancing, and Special Olympics. There is a pressing need to conduct studies using appropriately powered representative samples and to validate measures that assess physical activity less directly; including methodologies in which proxy respondents are used. Accurate information about existing patterns of behavior will enhance the development of effective strategies to promote physical activity among persons with mental retardation.

Background: Maintaining normal weight, engaging in the recommended level of exercise, and eating healthy food are known to improve general health. The impact of these behaviors on periodontal health is not well documented. This study is aimed at examining whether the increased number of these behaviors is associated with a decrease in the prevalence of periodontitis in a United States population. Methods: This study utilized data on 12,110 individuals who participated in the third National Health and Nutrition Examination Survey. Multivariate logistic regression analysis was used to estimate the association between the number of health enhancing behaviors and periodontitis prevalence. Health-enhancing behaviors included maintaining normal weight (body mass index [BMI], 18.5 to 24.9 kg/m²), engaging in the recommended level of exercises (≥5 episodes of moderate or ≥3 episodes of vigorous-intensity physical activity per week), and having a high quality diet (healthy eating index >80). Results: After controlling for age, gender, race\ethnicity, cigarette smoking, other tobacco products, education, diabetes, poverty index, census region, acculturation, vitamin use, time since the last dental visit, dental calculus, and gingival bleeding, a 1-unit increase in the number of the three health-enhancing behaviors was associated with a 16% reduction in the prevalence of periodontitis (odds ratio [OR] = 0.84; 95% confidence interval [CI]: 0.77 to 0.93). Individuals who maintained normal weight, engaged in the recommended level of exercise, and had a high-quality diet were 40% less likely to have periodontitis compared to individuals who maintained none of these health-enhancing behaviors. Conclusion: An increased number of health-enhancing behaviors is associated with a lower periodontitis prevalence. [ABSTRACT FROM AUTHOR]

ABSTRACT: This study explored relationships between perceived life satisfaction and physical activity behaviors in a statewide sample of adolescents in South Carolina (n = 4,758) using the CDC Youth Risk Behavior Survey (YRBS) and the Brief Multidimensional Student Life Satisfaction Scale (BMSLSS). Adjusted logistic regression analyses and multivariate models constructed separately revealed significant race by gender results. Not exercising for 20 minutes over the past 7 days (sweating and hard breathing), not performing stretching exercising (past 7 days), not exercising to strengthen or tone muscles (past 7 days), spending < 20 minutes actually exercising or playing sports in PE class, not playing on sport teams run by school, and not playing on sport teams run by outside school organizations were associated (p = .05) with reduced life satisfaction for specific race/gender groups. Results suggest implications for school and community-based physical activity programs. Future research should consider measures of life satisfaction as a component of comprehensive assessments of adolescent physical activity behaviors in fieldwork, research, and program evaluation.

ABSTRACT: This study tested the potential of a novel intervention addressing alcohol prevention within the context of a sport program. Study participants were randomly assigned to one of three groups, with one group receiving the sport consultation (Sport), a second the sport consultation plus an alcohol consultation (Sport Plus), and a third a sport consultation, alcohol consultation, and mailed parent print materials (Sport Plus Parent). Researchers recruited 465 eighth graders from three schools in the northeast Florida region to participate in the study. The Youth Alcohol and Health Survey(n1) was used to collect data on alcohol and drug consumption, alcohol use risk and protective factors, and exercise habits at baseline and three-month post-intervention. Significant time effects (p's < .05) were found on three of six alcohol measures, both exercise measures, and four risk/protective factors, with all but one risk factor showing improvements over time. Time by assignment by current drinking status (yes/no) interaction effects (p's < .05) were found on alcohol initiation, length of alcohol use, quantity, heavy use, moderate physical activity, and four risk/protective factors, with preintervention drinking adolescents exposed to the Sport intervention showing the greatest improvements on all but two measures. Findings suggest that a brief sport-based screen and consultation tailored to adolescents' health habits, with and without parent materials, may potentially reduce alcohol use while increasing exercise frequency.

This study was designed to examine factors influencing exercise behavior of older African American adults. Using the Transtheoretical Stages of Change Model and focus group methodology, 103 participants were assigned to gender and stage specific groups of 5 to 12 each. The focus group discussion guide was developed to explore the meaning of health and exercise, and factors that influence exercise behavior for each stage of the model. Responses varied by stage and gender. Men and women alike described health as the ability to remain active and participate in desired activities. The meaning of exercise varied, by stage, from the ability to perform household chores to engaging in aerobic activities. Many factors such as health, social support, efficacy, and motivation influenced the desire and ability to exercise. Women were more likely than men to identify family responsibility as a barrier to participation in exercise activities. Participants identified strategies to recruit and retain African American elders in exercise programs. Findings of the study have implications for health professionals designing exercise health promotion programs for older African American adults in community settings. [ABSTRACT FROM AUTHOR]
