Over 30 million Chinese children, aged between seven and 18, are overweight or obese - placing them at greater risk of early death and this number is set to rise to 50 million by 2030, caused in part by the role grandparents play in childcare.

Researchers at the Universities of Birmingham and Bristol worked with Guangzhou Centre for Disease Control and Prevention - enlisting 1,641 six-year-old children across 40 primary schools in Guangzhou to evaluate the effectiveness of the CHIRPY DRAGON program in tackling childhood obesity.

The 12-month randomized trial promoted physical activity and healthy eating behaviors among the children - discovering the significant reduction in weight gain among those participating in the CHIRPY DRAGON program, as well as higher consumption of fruit and vegetables, less screen-based sedentary activity and more physical activity.

Academics noting that health benefits were more marked in girls than boys, as female pupils gained less body fat than boys.

The study was part of the wider CHIRPY DRAGON program (Chinese pRimary school children PhYsical activity and DietaRy behAviour chanGe InterventiON), which has involved over 61,000 children at 43 primary schools across Guangzhou.

Dr. Bai Li conceived and managed the CHIRPY DRAGON study to completion at the University of Birmingham and now works within the Centre for Exercise, Nutrition and Health Sciences at the University of Bristol.

Dr. Li commented: "This study shows that an evidence-based obesity prevention program delivered through schools may offer a cost-effective way of reducing the emerging epidemic of childhood obesity in China.

"Future research should identify strategies to enhance beneficial effects among boys, and investigate the transferability of the intervention to other provinces in China and countries that share the same language and cultures.

"Our findings provide novel and important information for researchers, policymakers, and research funders in other countries. Several countries such as Malaysia, Singapore, and large population pockets in other countries such as Canada share language, dietary habits, and cultures with China.

"The problem of grandparent care in relation to childhood obesity is also common in non-Asian countries, including the UK. The intervention we evaluated in this study is the first childhood obesity prevention program that included a substantial component aimed at improving grandparents' childcare knowledge and skills."

Established in January 2014, the CHIRPY DRAGON program aimed to promote a healthier lifestyle and weight status among Guangzhou children by:

  • Improving health knowledge and practical skills in children, parents, and grandparents
  • Improving the nutritional quality of school lunches
  • Providing training for parents and children on simple ways to increase children's physical activity level outside school
  • Providing opportunities for more physical activity for children in school


Specially trained staff worked with children, as well as parents, grandparents and school teachers, to promote a healthier diet and more active lifestyle among the young.

Professor Peymane Adab, from the University of Birmingham, commented: "We found that in some settings, schools could play a part in the prevention of childhood obesity, although it is important to remember that support from the wider community and government are also important to achieve maximum impact.

"We hope that, as a result of the highly cost-effective CHIRPY DRAGON program, Guangzhou will be seen as a role model city for its work in tackling childhood obesity and inspire similar action in cities across China and around the world. This would help to reduce the burden on public health and improve the quality of life for millions of young people."

CHIRPY DRAGON is the first program of its kind to directly engage with Chinese grandparents, who are increasingly the main caretakers of children in three-generation families and have a greater say in youngster's eating behaviors and physical activity. Part of its focus was to encourage and support grandparents to promote healthier, more active lifestyle choices amongst children.

The team's previous research showed children in China mainly cared for by grandparents are twice as likely to be overweight or obese as those raised mainly by parents or other adults. They also discovered Chinese children who go to bed later and sleep less are more likely to be more overweight.

Dr. Wei Jia Liu, from Guangzhou Centre for Diseases Control and Prevention, commented: "I am very glad that the important findings of our CHIRPY DRAGON research are now published in PLoS Medicine. Childhood obesity is a major public issue affecting the health of Chinese children and adolescents. I hope the results of our research will contribute to the prevention and control of childhood obesity in China."
