Background:to investigate levels of physical activity (PA) and sedentary behavior (SB) in 10- to 14-year-olds and to determine PA differences between week-weekend days, genders and school stages.Methods:241 children were recruited from 15 primary and 15 secondary schools. PA was assessed for 7 days using the SenseWear Mini Armband and an electronic diary. Week-weekend and gender differences were determined using 2-way repeated-measures ANOVA. Combined intensity- and domain-specific PA differences between genders and school stages were examined using 2-way ANOVA.Results:Weekdays were more active compared with weekend days. Physical activity level (PAL) of boys was higher compared with girls. Boys showed more moderate (+15 min/day) and vigorous PA (+9 min/day), no differences were found for SB and light PA. Secondary school children showed more SB (+111 min/day), moderate (+8 min/day) and vigorous (+9 min/day) PA and less light PA (-66 min/day) compared with primary school children. No difference was found for PAL. The results of the combined intensity- and domain-specific parameters revealed more nuanced differences between genders and school stages.Conclusions:Our results demonstrate the complexity of PA and SB behavior of children, indicating the need for a multidimensional and differentiated approach in PA promotion.

The purpose of the present study was to examine the effects of height-adjustable standing desks on time-series variation in sedentary behavior (SB) among primary school children. Thirty-eight children aged 11–12 years (22 boys and 16 girls) from two classes at a primary school in Nagano, Japan, participated in this study. One class was allocated as the intervention group and provided with individual standing desks for 6 months, and the other was allocated as the control group. Time spent in SB, light-intensity physical activity (LPA), and moderate-to-vigorous-intensity physical activity (MVPA) was measured using accelerometers (ActiGraph) at baseline and follow-up. Time spent in SB was significantly lower by 18.3 min/day on average in the intervention class at follow-up (interaction effects: F(1, 36) = 4.95, p = 0.035, η2 = 0.082). This was accompanied by a significant increase in time spent in MVPA (+19.9 min/day on average). Our time-series analysis showed significant decreases in SB during school time, while no change in SB was found during non-school time. This result indicates that the use of standing desks promotes an overall reduction in SB with no compensatory increase during non-school time.

Background:This study investigates the influence of school playground facilities on children’s daily physical activity.Methods:Participants were 594 school children measured at preschool (age 6 to 7 years) and 3 years later in third grade (518 children age 9 to 10 years) from 18 schools in 2 suburban municipalities in Denmark. Physical activity data were obtained using accelerometers. These were related to the number of permanent play facilities in school grounds and the school playground area (m2).Results:The number of play facilities in the school grounds was positively associated with all measures of children’s activity. In preschool every 10 additional play facilities the children had access to was associated with an increase in the average accelerometer counts of 14% (r = .273, P < .001) in school time and 6.9% (r = .195, P < .001) overall. For the children in third grade, access to 10 additional play facilities was associated with an increase in school time activity level of 26% (r = .364, P < .001) and an increase in overall activity level of 9.4% (r = .211, P < .001). School playground area did not affect activity levels independently of the number of permanent play facilities.Conclusion:Increasing the number of play facilities in primary school playgrounds may increase the level of children’s daily physical activity.

AbstractObjectiveResults of the WHO European Childhood Obesity Surveillance Initiative indicated that on average one out of four primary-school children is overweight or obese. Portugal presented one of the highest prevalences of obesity. Childhood obesity prevention and treatment should be a top priority. The aim of the present study was to evaluate the effectiveness of Program Obesity Zero (POZ), a multi-component, community-, family- and school-based childhood obesity intervention.DesignParents and children attended four individual nutrition and physical activity counselling sessions, a one-day healthy cooking workshop and two school extracurricular sessions of nutrition education. Waist circumference, BMI, physical activity level, sedentary behaviours, and nutrition and physical activity knowledge, attitudes and behaviour were assessed at baseline and after 6 months. Diet was assessed using two 24 h recalls, at baseline and at 6 months.SettingFive Portuguese municipalities and local communities.SubjectsTwo hundred and sixty-six overweight children (BMI ≥ 85th percentile) aged 6–10 years, from low-income families in five Portuguese municipalities, were assigned to the intervention.ResultsChildren showed reductions in waist circumference (−2·0 cm; P < 0·0001), mean BMI (−0·7 kg/m2; P < 0·0001) and BMI-for-age percentile (−1·7; P < 0·0001) at 6 months. Overall, children's intake of fruit and vegetables was <400 g/d throughout the intervention. After 6 months, higher fibre consumption and an apparent decrease in sugary soft drinks intake to a quarter of that observed at baseline (mean intake: 198 ml/d at baseline), with improvements in physical activity levels and screen time <2 h/d, were also observed.ConclusionsThe findings suggested that POZ is a promising intervention programme, at municipality level, to tackle childhood overweight and obesity.
