ABSTRACT The purpose of the present study was to evaluate the effect of the Happy 10 programme on the promotion of physical activity, physical growth and development of primary school students, and on obesity control and prevention. Two similar primary schools from one district of Beijing, China were selected, one as an intervention school and the other as a control school. A Happy 10 programme was implemented at least once every school day in the intervention school for two semesters, whereas no intervention was adopted in the control school. The information on energy expenditure and duration of physical activity was collected by a validated 7-day physical activity questionnaire. Height and weight were measured by the trained investigators following standardized procedure. Energy expenditure and intensity of each Happy 10 session were measured by a physical activity monitor. The average energy expenditure and duration of total physical activity per day among students in the intervention school increased significantly from 15.0 to 18.2 kcal kg(-1) and 2.8 to 3.3 h, respectively, whereas the figures significantly decreased in the control school. There was a significant difference in change of weight and body mass index between girls in the intervention and control school (2.4 kg vs. 4.6 kg; 0.47 kg m(-2) vs. 0.66 kg m(-2)). The prevalence of overweight and obesity in the intervention school decreased by 0.4-5.6%, as compared with the increase by 0.6-4.5% in the control school. The average energy expenditure and intensity per 10-min session ranged from 25.0 to 35.1 kcal and from 4.8 to 6.2 kcal kg(-1) h(-1), respectively, in grades 1-5. The Happy 10 programme provides a useful strategy to promote physical activity among school children, and also plays a positive role in building up physical growth and development of girls.

    ABSTRACT: The prevalence of obesity among children and adolescents has been rapidly rising in Mainland China in recent decades, both in urban and rural areas. There is an urgent need to develop effective interventions to prevent childhood obesity. Limited rigid data regarding children and adolescent overweight prevention in China are available. A national random controlled school-based obesity intervention program was developed in the mainland of China. The study was designed as a national multi-centered cluster randomized controlled trial involving more than 70,000 children and adolescents aged 7-18 years from 7 provinces in China. In each center, about 12-16 primary and secondary schools, with totally at least 10000 participants were randomly selected (Primary: Secondary = 1:1). All of the selected schools were randomly allocated to either intervention or control group (Intervention: Control = 1:1).The multi-components school-based and family-involved scheme was conducted within the intervention group for 9 month, while students in the control group followed their usual health practice. The intervention consisted of four components: a) Create supportive school and family environment, b) Health lifestyles education and related compulsory physical activities, c) Instruct and promote school physical education, d) Self-monitor obesity related behaviors. Four types of outcomes including anthropometric, behavioral, blood chemical and physical fitness were measured to assess the effectiveness of the intervention program. This is the first and largest multi-centered school-based obesity intervention program with the consideration of geographical and social-demographic characteristics of the rapidly increased obesity prevalence of Chinese children and adolescent. The intervention is based on Social Cognitive Theory and Social-Ecological Model of Health, and follows a stepwise approach guided by PRECEDE-PROCEED (P-P) Model and Intervention Map. The results of and lesson learned from this study will help guide future school-based national childhood obesity prevention programs in Mainland China. January 22, 2015; NCT02343588.

    ABSTRACT: The purpose of this study was to evaluate the effects of multicomponent school based intervention constituted of diet modification, regular exercise and psychosocial consultation on body status in overweight and obese children and adolescents. And to come up with an appropriate intervention protocol for controlling children and adolescents obesity in Shantou city. Two schools were randomised to intervention group and control group respectively. A total of 41 students enrolled were diagnosed as overweight or obese. Twenty-six students of the intervention group completed the one-year intervention programme consisted of diet modification, regular exercise and psychological consultation except two of them were transferred to another school. The differences of BMI, anthropometric measures, metabolic profile and the scores of questionnaire and the scale were compared to evaluate the effects of the intervention programme. After one-year intervention, it observed in the intervention group that BMI-Z score, WHR and WHtR had significant improvements, and there was a nonsignificant trend (P=0.053) for a decrease in BMI-P. Fasting plasma glucose, cholesterol (CH) and low-density-lipoprotein cholesterol (LDL-C) levels in the intervention group showed nonsignificant trend for a decrease (PFPG=0.084, PCH=0.057, PLDLC=0.098), compared with a significant increase of triglycerides (TG) and LDL-C levels in the control group (PTG=0.041, PLDL-C=0.038). There were some positive dietary, physical activity, or sedentary behaviour changes found in the students of the intervention group as the scores of the questionnaire got significant improvement (P=0.04). Our one-year multicomponent school-based intervention programme did have positive effects to some extents on health state and lifestyle behaviour of overweight and obese children and adolescents, which indicated that it is feasible and important to implement such a school-based intervention programme in Shantou city.

    ABSTRACT: An increased prevalence of overweight/obesity among children has led to school district level policies to increase physical activity (PA) among elementary school students. Interventions are needed that increase activity levels without sacrificing time spent in academics. We evaluated a policy implementation intervention for to increase in-school PA in elementary schools in Forsyth County, North Carolina, in a randomized study with a delayed intervention control group. The study included third- through fifth-grade classrooms in eight elementary schools. Instant Recess® was used to introduce 10-minute PA breaks in classrooms on schedules determined by teachers. Direct observation was used to measure activity levels, other student behaviors, and teacher behaviors related to PA in the classrooms. Twenty-eight visits to schools were made during the spring and fall semesters of 2009. At baseline 11% to 44% of intervention and control schools were engaged in classroom-based PA. PA increased from baseline to spring follow-up in intervention schools and was maintained the following fall. Control schools decreased PA from baseline to spring and increased PA once they began the intervention. Students in classrooms engaged in Instant Recess exhibited statistically significant increases in light (51%) and moderate-intensity (16%) PA and increases in time spent in on-task behavior (11%). Control schools experienced similar benefits after they began implementing Instant Recess. Instant Recess is useful for increasing PA and improving behavior among elementary school children. Additional research may be needed to understand how to create policies supporting classroom activity breaks and how to assess policy adherence.
