Background: The main aim of the study was to examine the cross-sectional associations between objectively measured physical activity (PA) and body fatness in 7-12-year-old children. Methods: We performed an analysis of 365 children (209 girls). Participant recruitment was performed in eight randomly selected elementary schools in cities and towns with various numbers of inhabitants. The body composition analysis was performed according to a multi-frequency bioelectrical impedance analysis; PA was monitored using an accelerometer. Results: In terms of the overall PA, boys were more active than girls. No significant associations (unadjusted and adjusted models) were found between light PA and all body fatness indicators in either sex. Moderate-to-vigorous PA was significantly negatively associated with all body fatness indicators only in girls. These associations strengthened after adjustment for age, height and sedentary time (β ranging from-0.49 to-0.36, P ≤ 0.01). In contrast, vigorous PA was strongly negatively associated with body fatness indicators only in boys. In the fully adjusted model the significant negative associations were found for fat mass percentage (β =-0.15, P = 0.048) and fat mass index (β =-0.15, P = 0.040). Conclusions: The present study suggests that increasing sex-specific PA of different intensities may be an appropriate approach for decreasing body fatness in children. Longitudinal studies are needed to verify these associations.

Background This study examined the strength, shape and direction of associations of accelerometer-assessed overall, school- and non-school-based moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) with BMI among adolescents across the world. Second, we examined whether these associations differed by study site and sex. Methods Cross-sectional data from the IPEN Adolescent study, an observational multi-country study, were used. Participants wore an accelerometer for seven days, reported height and weight, and completed a socio-demographic survey. In total, 4852 adolescents (46.6% boys), aged 11–19 years (mean age = 14.6, SD = 1.7 years) were included in the analyses, using generalized additive mixed models. Results Adolescents accumulated on average 41.3 (SD = 22.6) min/day of MVPA and 531.8 (SD = 81.1) min/day of ST, and the prevalence of overweight and obesity was 17.2% (IOTF), but these mean values differed by country. Linear negative associations of acceleromete...

Obesity has been hypothesized to be associated with reduced moderate-to-vigorous physical activity (MVPA) and increased sedentary time (ST). It is important to assess whether, and the extent to which, levels of MVPA and ST are suboptimal among children and adolescents with obesity. The primary objective of this study was to examine accelerometer-measured time spent in MVPA and ST of children and adolescents with obesity, compared with MVPA recommendations, and with non-obese peers. An extensive search was carried out in Medline, Cochrane library, EMBASE, SPORTDiscus, and CINAHL, from 2000 to 2015. Study selection and appraisal: studies with accelerometer-measured MVPA and/or ST (at least 3 days and 6 h/day) in free-living obese children and adolescents (0 to 19 years) were included. Study quality was assessed formally. Meta-analyses were planned for all outcomes but were precluded due to the high levels of heterogeneity across studies. Therefore, narrative syntheses were employed fo...

Objective: The prevalence of overweight and obesity among children and adolescents increased dramatically. Reduced regular physical activity (PA) is considered one of the major factors behind this worldwide epidemic and related health problems. This study aimed to determine the association between PA level and body composition components in 12-14 years old girls and boys living in Altındağ district, Ankara. Materials and methods: A total of 234 boys and 224 girls aged 12-14 years participated in this study. PA level was assessed by the Physical Activity Questionnaire for Children (PAQ-C) and body composition was measured by bioelectric impedance. Two-way ANOVA with Bonferroni post hoc test and Pearson Correlation Coefficient tests were used in data analysis. Results: Findings of the study showed that children aged 12 years had higher total PA score than aged 13 and 14 years (p<0.05), showing decreased PA level with age. Boys had significantly higher total PA score in all age grou...
Physical Activity, Sedentary Time, and Obesity in an International Sample of Children

To determine the relationships between moderate-to-vigorous physical activity (MVPA), vigorous physical activity (VPA), sedentary time and obesity in children from 12 countries representing a wide range of human development. Methods: The sample included 6,539 children aged 9-11 years. Time in MVPA, VPA and sedentary behaviors were assessed by accelerometry. The body mass index (BMI; kg/m 2 ) was used to classify children as obese based on z-scores (>+2 SD) from World Health Organization reference data. Results: The mean (SD) times spent in MVPA, VPA and sedentary behavior were 60 (25) min/day, 18 (11) min/day and 513 (69) min/day, respectively. The overall proportion of the sample that was obese ranged from 5.2% to 24.6% across sites. The odds ratios for obesity were significant for MVPA (0.49; 95% CI: 0.44 -0.55), VPA (0.41; 0.37 -0.46) and sedentary time (1.19; 1.08 -1.30) in the overall sample. The associations of MVPA and VPA with obesity were significant in all 12 sites, whereas the association between sedentary time and obesity was significant in 5 of the 12 sites.

Advances in technology have improved our ability to measure physical activity in free-living humans. In the last few years, several large epidemiological studies in Europe and the United States have used accelerometers to assess physical activity in children and adolescents. The use of accelerometers to study physical activity has presented some challenges on how to summarise and interpret the data that they generate, however these studies are providing important information on the levels and patterns of physical activity among children and adolescents. Some studies have reported that few children and adolescents appear to meet the recommended minimum of 60 minutes of moderate to vigorous activity per day. Accelerometers have also allowed examination of the relationships between physical activity and health outcomes like obesity and other chronic disease risk factors such as insulin resistance, aerobic fi tness, blood lipids and blood pressure. Use of accelerometers allows such relationships to be estimated with a precision that was previously impossible with self-report measures of physical activity. Such information is already advancing our understanding of the role that physical activity plays in preventing childhood obesity and cardiovascular disease risk.

Globally, public health policies are targeting modifiable lifestyle behaviours. We explore the independent association of moderate-to-vigorous physical activity (MVPA) and sedentary behaviour on the risk of childhood overweight/obesity. A cross-sectional survey of children aged 8-11 years (N=826). Objective body mass index was used to classify children as normal weight or overweight/obese. Children wore wrist-worn Geneactiv accelerometers for 7-days and thresholds were applied to categorise MVPA and sedentary time. Screen time (ST) was parent reported. Poisson regression examined the independent association of (1) MVPA, (2) objective sedentary time and (3) ST on the risk of overweight/obesity. Overall, 23.7% (95% CI, 20.8-26.6%) of children were overweight/obese. On average, children spent 10.8% of waking time at MVPA and 61.3% sedentary. One-fifth (22.1%, 95% CI, 19.3-25.0%) of children achieved MVPA recommendations (≥60 minutes each day) and 17.5% (95% CI, 14.9-20.1%) met ST recom...

The amount of time children spend in sedentary behaviours may have adverse health effects. To examine the substitution effects of displacing a fixed duration of sedentary time with physical activity (PA) on children's body composition. We included 386 children (197 boys). Outcomes were body mass index, waist circumference, total body fat mass and trunk fat mass assessed by dual-energy X-ray absorptiometry. Sedentary time and PA were measured with accelerometers. Data were analysed by isotemporal analyses estimating the effect of reallocating 15 and 30 min d(-1) of sedentary time into light (light physical activity), and moderate-to-vigorous (MVPA) PA on body composition. Reallocating 15 and 30 min d(-1) of sedentary time into MVPA was negatively associated with body fatness in cross-sectional analyses. Prospectively, reallocating 30 min of sedentary time into 30 min of MVPA was negatively associated with waist circumference (β = -1.11, p < 0.05), trunk fat mass (β = -0.21, p ...
