This study aimed to evaluate the relationship between parental body weight and their children's overweight and obesity in school students in Gao Hang Town, Shanghai.
A cross-sectional study was performed in five primary schools in Gao Hang Town, Shanghai. Overall, 2,025 sets of parents and their children (7-13 years, 981 boys/1044 girls) were enrolled. Body mass index (BMI) and waist circumference for each child were measured. Age, gender, birth weight, and breastfeeding history was recorded for each child and the BMI of their parents was obtained by a self-completion questionnaire. Overweight (including obesity) was defined as a BMI of >=24.0 kg/m2 in parents and a BMI >=P85 in children according to age- and gender-specific percentiles. Re-sults: The total prevalence of overweight was higher in boys than in girls (35.5% vs 19.5%), while it was the same in fathers compared with mothers (50.6% vs 18.9%). The prevalence of overweight in boys showed a trend with increasing age, but remained stable versus age in girls. Parents were further divided into four subgroups as follows: I) both father and mother had a normal BMI; II) father overweight, mother normal weight; III) father normal weight, mother overweight; IV) both father and mother are overweight. The odds ratio of overweight was 2.26 for group II, 2.71 for group III, and 4.36 for group IV, respectively, compared with group I. Gender, paternal BMI, and maternal BMI were chosen as risk factors for children overweight.
Parental BMI affects their offspring overweight and obesity in Chinese school students.
本研究旨在评估上海高行镇在校学生中父母体重与子女超重及肥胖之间的关系。
在上海高行镇的五所小学开展了一项横断面研究。共纳入2025对父母及其子女（7至13岁，男孩981名/女孩1044名）。测量了每个孩子的体重指数（BMI）和腰围。记录了每个孩子的年龄、性别、出生体重和母乳喂养史，并通过自填问卷获取其父母的BMI。根据年龄和性别的特定百分位数，超重（包括肥胖）定义为父母BMI≥24.0kg/m²，孩子BMI≥P85。结果：男孩超重的总患病率高于女孩（35.5%对19.5%），而父亲与母亲的超重患病率相同（50.6%对18.9%）。男孩超重患病率随年龄增长呈上升趋势，而女孩超重患病率随年龄保持稳定。父母进一步分为以下四个亚组：I）父亲和母亲BMI均正常；II）父亲超重，母亲体重正常；III）父亲体重正常，母亲超重；IV）父亲和母亲均超重。与I组相比，II组、III组和IV组超重的比值比分别为2.26、2.71和4.36。将性别、父亲BMI和母亲BMI作为儿童超重的危险因素。
在中国在校学生中，父母的BMI会影响其子女的超重和肥胖情况。
