ABSTRACT

Background: The prevalence of childhood obesity among adolescents has been rapidly rising in Mainland China in recent decades, especially in urban and rich areas. There is an urgent need to develop effective interventions to prevent childhood obesity. Limited data regarding adolescent overweight prevention in China are available. Thus, we developed a school-based intervention with the aim of reducing excess body weight in children. This report described the study design.

Methods/design: We designed a cluster randomized controlled trial in 8 randomly selected urban primary schools between May 2010 and December 2013. Each school was randomly assigned to either the intervention or control group (four schools in each group). Participants were the 4th graders in each participating school. The multi-component program was implemented within the intervention group, while students in the control group followed their usual health and physical education curriculum with no additional intervention program. The intervention consisted of four components: a) classroom curriculum, (including physical education and healthy diet education), b) school environment support, c) family involvement, and d) fun programs/events. The primary study outcome was body composition, and secondary outcomes were behaviour and behavioural determinants.

Discussion: The intervention was designed with due consideration of Chinese cultural and familial tradition, social convention, and current primary education and exam system in Mainland China. We did our best to gain good support from educational authorities, school administrators, teachers and parents, and to integrate intervention components into schools' regular academic programs. The results of and lesson learned from this study will help guide future school-based childhood obesity prevention programs in Mainland China.

Mentions: This school-based C-RCT has being conducted from May 2010 to December 2013 in Nanjing, a large city in eastern China which had a registered population of more than 6.2 million in 2009. The intervention took place within Jianye, an urban district of Nanjing. In 2009, there were 13 primary schools in Jianye district, among which eight schools were randomly selected as target schools and randomly assigned to either the control or intervention group (four schools in each group). All the fourth graders in each of the selected schools were invited to participate in the study. Written informed consent was obtained from both the schools and parents/students’ guardians. Figure 1 presents the study mapping process. Although the entire project was designed to be three and half a year, the field intervention was planned to be implemented among intervention group within one academic year from May 2010 to April 2011, while three surveys were scheduled to collect data from all participants (both intervention and control groups) in this study: (1) The first survey was conducted in May 2010 to collect baseline data; (2) The second was in May 2011 to gather data for evaluating the intervention effectiveness immediately after field intervention; (3) The third will be in May 2012 to collect data also for assessing the intervention effectiveness one-year later after field intervention. This study was approved by the academic and ethical committee of Nanjing Municipal Center for Disease Control and Prevention.
