BACKGROUND: The purpose was to evaluate the relationship between adherence to pediatric 24-hour movement guidelines (moderate-to-vigorous physical activity (MVPA), sedentary behavior and sleep) and cardiometabolic risk factors. METHODS: The sample included 357 white and African American children aged 5-18 years. Physical activity, TV viewing and sleep duration were measured using questionnaires, and the 24-hour guidelines were defined as: ≥60 min/day of MVPA on ≥5 days/week, ≤2 h/day of TV, and sleeping 9-11 h/night (ages 5-13 y) or 8-10 h/night (ages 14-18 y)...

BACKGROUND: Increasing access and opportunity for physical activity (PA) in schools are effective; however, not everyone experiences the same effects. Prompting and reinforcement may encourage more frequent participation in recreational PA during the school day. The purpose of this study was to investigate a lunchtime PA intervention on whole-school PA participation, and if behavioral support enhanced these effects. METHODS: A modified reversal design compared an environmental and an environmental plus behavioral support intervention on lunchtime PA participation versus baseline levels in a suburban junior high school in the western US (N = 1452)...

BACKGROUND: A limitation of accelerometer measures of moderate-to-vigorous physical activity (MVPA) is non-wear time. Non-wear time data is typically deleted prior to estimating MVPA. In this study we used an approach that used socio-demographic, health, and time data to guide the imputation of non-wear time data. We determined if imputing non-wear time data influences estimates of MVPA and the association between MVPA, body mass index, and blood pressure. METHODS: Seven days of accelerometer data were collected on 332 children aged 10-13 years...

BACKGROUND: As there is not a gold standard methodology to classify older people in relation to physical activity (PA) and sedentary behavior (SB), this paper aimed to propose a classification combining PA and SB. METHODS: Within a broader study, 433 subjects, aged over 55 years (57% females) from Madrid and Majorca, were evaluated for PA and SB by means of validated questionnaires. Physical fitness was analyzed objectively using the EXERNET test battery. Cluster analyses were used to establish behavioral patterns, combining PA and SB...

BACKGROUND: Many mothers and young children are not meeting physical activity guidelines. Parent-child co-participation in physical activity (i.e., shared physical activity) provides opportunities for social modeling and might be associated with child physical activity. There is very little information about shared physical activity using objective measures. METHODS: Participants (N=17 mother-young child dyads) completed a demographic survey, height/weight measurements, and wore a Bluetooth® accelerometer for one week...

BACKGROUND: Active travel to school (ATS) is positively associated with various health indicators. The rapid social, economic and environmental changes in China provide a unique setting to study changes and predictors of ATS over time. METHODS: Using logistic regression modeling, we analyzed data from the China Health and Nutrition Survey during 1997-2011 (N=9487, ages 6-17 years) to estimate the change over time in ATS and to identify associated factors. RESULTS: The prevalence of reported ATS among children dropped from 95...

BACKGROUND: There are many purported benefits to recess including engaging in physical activity, forming positive peer relationships, and taking a break from the classroom. Current research, however, is inconclusive regarding the presence of gender and developmental differences in physical activity that takes place during recess. The purpose of this study was to examine differences in the amount of physical activity that occurs during recess across gender and grade level. METHOD: Students from first and sixth grade classrooms participated in the study, and physical activity was measured using accelerometers to record the number of steps taken during recess...

BACKGROUND: Regular physical activity is a key way to prevent disease. However, we have a limited understanding of the socioeconomic precursors and glucoregulatory sequelae of engaging in physical activity in different domains. METHODS: We examined the associations among lifecourse socioeconomic disadvantage, meeting the physical activity guidelines with leisure-time physical activity (LTPA), occupational physical activity (OPA), or household physical activity (HPA), and prediabetes and diabetes in the MIDUS (Midlife in the U...

BACKGROUND: patients on hemodialysis (HD) report lower physical activity (PA) levels. We analysed factors associated with low levels of PA in patients with chronic kidney disease (CKD) and compared PA on HD day and non-HD. METHODS: 79 patients wore an accelerometer and were classified according to time spent on moderate-vigorous PA (MVPA). Demographic data, BMI, comorbidities, clinical status and health related quality of life (HRQoL) were checked for association with PA...

BACKGROUND: Although the relationship between physical activity and arterial stiffness has been shown in healthy persons, it remains controversial in obese persons. METHODS: From January to September 2014, we evaluated 795 obese subjects from 25 public health centers in Seoul. We compared physical activity and brachial-ankle pulse wave velocity (baPWV) between obese subjects with metabolic syndrome (MetS) (MO) and obese subjects without MetS (NMO). RESULTS: The MO group had more men, higher body mass index (BMI), higher fasting glucose level, lower high-density lipoprotein-cholesterol level, and higher triglyceride level...
