Abstract

Objective To obtain the epidemiological characteristics of childhood obesity in Nanjing by analyzing the data of childhood obesity under 7 years old in the previous study "Physical Development survey of children under 7 years old in Nine Chinese cities". Methods In 1986, 1996, 2006 and 2016, the stratified cluster random sampling method was adopted to select 10 000 children under 7 years old from Qinhuai District and Jiangning District of Nanjing, and physical data were collected to calculate the detection rate of obesity and overweight in different age groups and genders in previous surveys. Results 1) The detection rate of obesity was 0.308% in 1986, 1.76% in 1996, 4.83% in 2006 and 4.42% in 2016.The detection rate of obesity in 2006 was the highest, which was slightly lower in 2016. 2) In 1996, 2006 and 2016, the detection rate of obesity in children under 7 years old showed a trend of first decreasing and then gradually increasing with the increase of age. The detection rate of obesity in 1-year-old and 2-year-old children was lowest, which gradually increased with age from 3 years old. 3) In 2016, the overall detection rate of overweight among children under 7 years old and the detection rate in children at all age groups were all higher than that in 2006. 4) In 2006 and 2016, the overall detection rate of obesity in boys under 7 years old was higher than that of girls. Conclusion Childhood obesity is still a major problem in children's health, and the intervention of childhood obesity is a long-term and arduous work.
