          Results The detection rates of overweight and obesity of children and adolescents in Jiangxi province were 20.5% and 8.4%, respectively. Which decreased with the increase of the learning stage (χ 2 = 178.65, 389.86), with significantly higher in boys and urban areas (χ 2 = 1 061.06, 504.21; 56.17, 34.14) ( P<0.01). In different economic areas, the detection rates of overweight and obesity in moderate economic area (23.3%, 9.7%) were the highest, followed by high economic area (21.1%, 8.7%) and low economic area (18.2%, 7.2%), and the differences were statistically significant (χ 2 = 266.29, 143.90, P<0.01). The results of multivariate Logistic regression analysis showed that in terms of social demography, overweight and obesity of children and adolescents in Jiangxi Province were associated with economic area, residence, learning stage and gender; in terms of dietary behavior, overweight of children and adolescents in Jiangxi Province was associated with consumption frequency of sugary drinks, sweets, fresh fruits and vegetables, and the influencing factors of obesity were consumption frequency of sweets and fresh fruits ( P <0.05).
