Abstract [en]

Background: Childhood obesity has become a health problem in urban areas in China. Intervention to reduce childhood obesity should be of high priority. School-based intervention programmes are needed to deal with the growing prevalence of childhood obesity in China.

Methods: Five primary schools were selected randomly for this study in the Beijing urban area in China; two were allocated to the intervention group and three to the control group. A total of 2425 children (1029 children in intervention schools and 1396 children in control schools) took part in the study for 3 years. In the intervention group, children and their parents were involved in a programme of nutrition education and physical activity. Control school students followed their usual health and physical education curriculum with no extra intervention.

Results: After the 3-year intervention, the prevalence of overweight and obesity were significantly lower in the intervention schools than in the control schools (overweight: 9.8% vs. 14.4%, P < 0.01; obesity: 7.9% vs. 13.3%, P < 0.01). The prevalence of overweight and obesity decreased by 26.3% and 32.5% in intervention schools respectively after intervention. The prevalence of overweight and obesity increased in control schools. There was also significant difference in body mass index between intervention and control schools (18.2 ± 2.6 vs. 20.3 ± 3.4, P < 0.01) after intervention. More non-obese children became obese in the control schools (7.0%) than in the intervention schools (2.4%) at end line (P < 0.01). Among the children who were obese at baseline, 49.2% remained obese at end line in intervention schools while 61.9% remained obese in control schools (P < 0.01).

Conclusions: Our study showed that an intervention programme could be feasible in schools in Beijing, China. The prevalence of overweight and obesity was reduced in schoolchildren in Beijing through an intervention focused on nutrition education and physical activity. Overweight and obesity children as well as normal weight children and their parents should be involved in such an intervention programme.

Abstract [en]

Childhood obesity appears to be increasing throughout the world. China has joined the global epidemic. Childhood obesity is not only a chronic disease which is associated with lifestyle, but also a public health problem in children. Obesity intervention should become a public health priority in China. This thesis reports on intervention to treat and prevent childhood obesity. The field work was implemented in Beijing, China.

This thesis is based on four papers: Paper I evaluated the feasibility and impact of family-based behavior treatment on obese children. Two years of intervention resulted in obese children with improvements in body mass index, total cholesterol, triglycerides, and blood pressure.

Paper II assessed the effects of a school-based intervention on obesity among primary school children. After a three-year intervention, the prevalence of overweight and obesity were significantly lower in the intervention schools than in the control schools. Fewer non-obese children became obese in the intervention schools than in the control schools.

Paper III explored the family related factors of overweight in 2- to 6-year-old children. Significant associations were observed between children’s overweight and parent characteristics for frequency of eating in restaurants, daily time spent viewing television, and engaging in physical activity. Child overweight was associated with parental overweight, low maternal education level and television watching >2h/d.

Paper IV investigated how grandparents influence their young grandchildren’s eating behaviors in Chinese three-generation families, using qualitative method. Three domains identified through the seven themes included: (1) Grandparents as primary caretakers of children in the three-generation family, (2) Grandparents' attitudes to child nutrition and healthy eating habits, and (3) The role of food as an educational and emotional tool. The results showed that nutrition education involving grandparents is thus a potential framework for improving healthy dietary behaviors in young children.
