Abstract
BACKGROUND: The pattern of urban-rural disparity in childhood obesity varies across countries. The present study examined the change trend of urban-rural disparity in childhood overweight and obesity from 1985 to 2014 in Shandong, China. METHODS: Data for this study were obtained from four cross-sectional surveys of school children carried out in 1985, 1995, 2005 and 2014 in Shandong Province, China. In this study, 39 943 students aged 7-18 years were included (14 458 in 1985, 7198 in 1995, 8568 in 2005 and 9719 in 2014). Height and weight of all subjects were measured; body mass index (BMI) was calculated from their height and weight. The BMI cutoff points recommended by the International Obesity Task Force were used to define overweight and obesity. RESULTS: The prevalence of overweight and obesity was increasing continuously both in urban and rural areas over the past 29 years (1985-2014). The prevalence of combined overweight and obesity was significantly higher in urban than in rural children and adolescents in 1985, 1995 and 2005 (p < 0.01). However, a rapid increase in the prevalence of combined overweight and obesity was observed in rural areas after 2005; as a result, the urban-rural disparity was getting narrower, and no significant urban-rural disparity was observed in 2014 (p > 0.05). CONCLUSION: The change trend of urban-rural disparity should be concerned in the future; policies and interventions focused on childhood overweight and obesity should pay attention to rural areas.
