BACKGROUND: To better understand the unique challenges of Appalachians, community-based studies are needed to establish benchmark rates. This study compares obesity rates and obesogenic behaviors among Appalachian adolescents to other adolescent populations or clinical recommendations. METHODS: This study was conducted in 11 Appalachian schools. Body mass index, body mass index percentile, and body fat percentage were measured using a Tanita DC-430U analyzer. Physical activity was measured using Actigraph wGT3X-BT accelerometers...

BACKGROUND: Physical activity guidelines state that children should achieve at least 60 minutes of moderate to vigorous physical activity (MVPA) on each day of the week. Accurate assessment of adherence to these guidelines should, ideally, include measurement over 7 days. When less than 7 days of data are available, researchers often report the average minutes of MVPA per day as a proxy for 7-day measurement. The aim of this study was to compare prevalence estimates generated by average MVPA per day versus MVPA assessed over 7 days...

BACKGROUND: Many parents are insufficiently active. Further research is needed to understand the goals that drive sustained exercise participation among parents. The purpose of this study was to use self-determination theory derived constructs to examine the relationship between parents' exercise goals and their autonomous motivation, controlled motivation, and exercise behavior across 1 year. METHODS: Mothers (n = 226) and fathers (n = 70) of children less than 16 years completed the Exercise Motivations Inventory-2 and, 1 year later, the Behavioral Regulation in Exercise Questionnaire-2 and Godin Leisure-Time Exercise Questionnaire...

BACKGROUND: This study examined the association between residential segregation and obesity for Whites, African Americans, Hispanics, and Asians. This study considered 3 dimensions of residential segregation, isolation, dissimilarity, and concentration. METHODS: By combining individual-level data from the Behavioral Risk Factor Surveillance System and county-level data from the County Health Rankings and Roadmaps, the total sample size was 204,610 respondents (160,213 Whites, 21,865 African Americans, 18,027 Hispanics, and 4505 Asians) from 205 counties in the United States...

BACKGROUND: The obesity epidemic is a global concern. Standard behavioral treatment including increased physical activity, reduced energy intake, and behavioral change counseling is an effective lifestyle intervention for weight loss. PURPOSE: To identify distinct step count patterns among weight loss intervention participants, examine weight loss differences by trajectory group, and examine baseline factors associated with trajectory group membership. METHODS: Both groups received group-based standard behavioral treatment while the experimental group received up to 30 additional, one-on-one self-efficacy enhancement sessions...

BACKGROUND: This study gauged the cost-effectiveness of a community-based health coaching intervention aimed at improving diet and physical activity among women in culturally diverse communities. METHODS: The Coalition for a Healthier Community for Utah Women and Girls recruited women from 5 cultural and ethnic groups and randomized them to receive quarterly versus monthly health coaching. Coaching was performed by trained community health workers from the targeted communities...

BACKGROUND: Sedentary behaviors (SB) may exacerbate loss of muscle mass and function, independent of physical activity levels. This study examined the associations of SB with abdominal muscle area and density, a marker of muscle quality, in adults. METHODS: A total of 1895 participants from the Multi-Ethnic Study of Atherosclerosis completed detailed health history, physical activity and SB questionnaires, computed tomography to quantify body composition, and measurements of inflammatory markers...

BACKGROUND: Recess strategies that increase children's physical activity and contribute to the daily 60 minutes of moderate to vigorous physical activity (MVPA) are recommended. METHODS: A cluster randomized trial was conducted to examine the effect of supervised versus organized recess on children's participation, physical activity, play, and social behavior. In supervised recess, children were free to play, and physical education (PE) teachers ensured safety. In organized recess, PE teachers provided challenging tasks...

BACKGROUND: Limited research examines the influence of sit-stand desks on ratings of discomfort, sleepiness, and fatigue. This study evaluated the time course of these outcomes over 1 day. METHODS: Adults (N = 25) completed a randomized cross-over study in a laboratory with two 8-hour workday conditions: (1) prolonged sitting (SIT) and (2) alternating sitting and standing every 30 minutes (SIT-STAND). Sleepiness was assessed hourly. Discomfort, physical fatigue, and mental fatigue were measured every other hour...

BACKGROUND: Compulsive exercise (CE) is a harmful form of exercise that elevates the risk of developing/sustaining clinical eating disorders. College-aged sorority women are especially prone to CE. Due to the pronounced impact social relationships have on college students' behavior, this study aims to examine personal networks and CE among a sample of sorority women through an egocentric network analysis. METHODS: A total of 204 women in a sorority from a large, private university in the southeastern United States completed a cross-sectional survey in spring 2015...

BACKGROUND: Men with prostate cancer (PCa) may be referred to cardiac rehabilitation (CR) following a significant cardiac event, but it is unknown if these men have different effects of CR from men without a history of PCa. PURPOSE: To compare the effect of CR on cardiorespiratory fitness (VO2 peak), body fat percentage, and body mass index in men with and without a history of PCa. METHODS: CR participants with PCa were retrospectively compared with a cohort matched on age, clinical indication for CR, and date of referral to the CR program...

BACKGROUND: This study aimed to estimate the prevalence and trends of participation in physical activity (PA) in Korean adults. METHODS: The Korea National Health and Nutrition Examination Survey (KNHANES; 2009-2013) and the Korea Community Health Survey (KCHS; 2009-2013) were used to estimate the prevalence of PA. Age standardization was performed using population projections for Korea in 2005 as a standard population. Trends of the prevalence from 2009 to 2013 were assessed by joinpoint regression analysis...

BACKGROUND: Physical activity health promotion coalitions are uncommon but important for beneficial collective impact on public health. The authors sought to obtain the viewpoints of member organizations of an Australian physical activity alliance, the National Physical Activity Alliance. METHODS: The authors conducted an online survey regarding member agenda, commitment, and vision for the alliance. Questions were mostly open ended (eg, "What are the 3 areas of priority related to physical activity that you would like The Alliance to focus on?")...

BACKGROUND: Time spent in university represents a period of transition and may be an appropriate time to promote physical activity among young adults. The aim of this study was to assess participation of university students in sport and physical activity in Ireland and to explore the association between physical activity and perceptions of overall health, mental health, and happiness. METHODS: The Student Activity and Sport Study Ireland was a cross-sectional online survey among a representative sample (n = 8122) of university students in Ireland...

BACKGROUND: The investigation sought to (1) establish the extent of injuries, (2) determine the odds of sustaining an injury, and (3) calculate the injury incidence rate in nonprofessional salsa dance. METHODS: Salsa dancers completed an anonymous web-based survey containing 11 demographic background and 10 (1 y retrospective) injury history questions. RESULTS: The response rate was 77%. The final sample of respondents included 303 women and 147 men, of which 22% and 14%, respectively, sustained ≥1 injury during salsa dance in the past year...

BACKGROUND: School physical education (PE) is one of the most effective public health tools to increase youth physical activity, yet compliance with PE mandates is low. In an effort to ensure adherence to state PE law, a 2013 lawsuit was filed against 37 California school districts that were found to be noncompliant. This study sought to assess school personnel's perceptions of the lawsuit's impact on PE mandate compliance, understand barriers and facilitators to lawsuit compliance, and identify potential unintended consequences of the lawsuit...

BACKGROUND: The purpose of this study was to determine if the Go Nutrition and Physical Activity Self-Assessment in Child Care (Go NAP SACC) intervention was effective in improving best practices in the areas of infant and child physical activity and outdoor play and learning in family child care homes (FCCHs) in Nebraska. METHODS: FCCHs (n = 201) participated in a pre-post evaluation using the Infant and Child Physical Activity and Outdoor Play and Learning assessments from the Go NAP SACC validated measure to assess compliance with best practices...

BACKGROUND: Neutrophil gelatinase-associated lipocalin (NGAL) is a glycoprotein released during early phases of a postischemic kidney in response to kidney injury, inflammation, and oxidative stress. It can be detected in urine after 2 hours of an ischemic event. The aim was to measure and to correlate the level of urine NGAL (uNGAL) with urea, creatinine, and glomerular filtration rate (GFR) of endurance cycling athletes (n = 19) and physically active individuals (control, n = 17)...

BACKGROUND: Direct observation protocols may introduce variability in physical activity estimates. METHODS: Thirty-five physical education lessons were video recorded and coded using the System for Observing Fitness Instruction Time (SOFIT). A multistep process examined variability in moderate to vigorous physical activity (MVPA%; walking + vigorous/total scans). Initially, per-SOFIT protocol MVPA% (MVPA%SOFIT) estimates were produced for each lesson. Second, true MVPA% (mean MVPA% of all students using all observations, MVPA%true) estimates were calculated...
