Objective To investigate prevalence and influencing factors of overweight and obesity among children and adolescents in Jiangxi Province, and to provide the basis for strategies for prevention and treatment of overweight and obesity.
Methods Using stratified random cluster sampling, a total of 77 780 primary and middle school students in 11 districts of Jiangxi Province were investigated with physical examination and questionnaire during March to November in 2019.
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).

【摘要】 目的 了解江西省儿童青少年超重肥胖现状及其影响因素, 为制定超重肥胖防治策略提供依据。 方法 采用分 层随机整群抽样方法, 于 2019 年 3—11 月对江西省 11 个设区市 77 780 名中小学生进行体格检査和问卷调査。 结果 江 西省儿童青少年超重检出率为 20.5%, 肥胖检出率为 8.4%。超重和肥胖检出率均随着学段的上升呈下降趋势 (χ 2 值分别 为 178.65, 389.86), 男生均髙于女生 (χ 2 值分别为 1 061.06, 504.21), 城区均髙于郊县 (χ 2 值分别为 56.17, 34.14) ( P 值均<0.01)。不同经济片区中, 中片区 (23.3%, 9.7%) 的超重和肥胖检出率最髙, 其次为好片区 (21.1%, 8.7%)、差片区 (18.2%, 7.2%), 且差异均有统计学意义 (χ 2 值分别为 266.29, 143.90, P 值均<0.01)。多因素 Logistic 回归分析结果显示, 社会人口 学方面, 江西省儿童青少年超重和肥胖的影响因素均为经济片区、居住地、学段和性别;饮食行为方面, 超重的影响因素为 含糖饮料、甜食、新鲜水果和蔬菜食用频率, 肥胖的影响因素为甜食、新鲜水果食用频率 ( P 值均<0.05)。 结论 江西省儿 童青少年超重肥胖形势严峻, 应在社会、学校、家庭的共同努力下进行综合防控。
