Data was limited on prevalence of overweight and obesity among primary school-aged children in Jiangsu Province. We aimed to present the current situation of obesity in Jiangsu Province and explore the relationship between obesity and other common diseases in children.
Physical examination among children aged 7 to 14 years in Jiangsu Province was conducted since 2014, and more than one third primary schools were covered annually. The physical measurements included body height, weight, blood pressure, vision, sex, age, and so on.
The prevalence of overweight and obesity among primary school children was 15.2% (18.7% for male students and 11.0% for female students), and 11.7% (14.5% for male students and 8.2% for female students) respectively. Obesity/overweight prevalence varied by regions. Among them the lowest prevalence was found in the southern region of Jiangsu Province, where residents had the highest average income level. Obesity group had elevated blood pressure comparing with the normal group, and obesity group especially in the male children aged 7 to 12 years had a higher prevalence of uncorrected visual acuity (UCVA) than that of normal group.
This study found that obesity/overweight prevalence differed by sex, age, and regions in Jiangsu Province. In addition, obese children were closely associated with other common disease. Further studies are needed to explore the basis of biological and statistical theories.
江苏省小学生超重和肥胖的患病率数据有限。我们旨在介绍江苏省肥胖的现状，并探讨肥胖与儿童其他常见疾病的关系。
自 2014 年以来，对江苏省 7 至 14 岁儿童进行了体格检查，每年覆盖三分之一以上的小学。体格测量包括身高、体重、血压、视力、性别、年龄等。
小学生超重和肥胖的患病率分别为 15.2%（男生 18.7%，女生 11.0%）和 11.7%（男生 14.5%，女生 8.2%）。肥胖/超重的患病率因地区而异。其中，江苏省南部地区的患病率最低，当地居民的平均收入水平最高。与正常组相比，肥胖组的血压升高，肥胖组尤其是 7 至 12 岁的男童，未矫正视力（UCVA）的患病率高于正常组。
本研究发现，江苏省肥胖/超重的患病率在性别、年龄和地区上存在差异。此外，肥胖儿童与其他常见疾病密切相关。需要进一步研究探索生物学和统计学理论的基础。
