Examine mother-son, mother-daughter, father-son and father-daughter resemblance in weight status, and potential modifying effects of socio-demographic and childcare characteristics.
Cross-sectional study.
School.
1973 school-age children and their parents from five mega-cities across China in 2017.
Pearson correlation coefficients (r) for BMI of father-son, father-daughter, mother-son and mother-daughter pairs were 0·16, 0·24, 0·26 and 0·24, respectively, while their weighted kappa coefficients (k) were 0·09, 0·14, 0·04 and 0·15, respectively. Children aged 6-9 years (r ranged from 0·30 to 0·35) had larger BMI correlation with their parents than their counterparts aged 10-14 years or 15-17 years (r ranged from 0·15 to 0·24). Children residing at home (r ranged from 0·17 to 0·27) had greater BMI correlations with their parents than children residing at school/other places. BMI correlation coefficients were significant if children were mainly cared for by their mothers (r ranged from 0·17 to 0·29) but non-significant if they were mainly cared for by others. Only children who ate the same meal as their parents 'most times' (r ranged from 0·17 to 0·27) or had dinner with their parents 'at most times' (r ranged from 0·21 to 0·27) had significant BMI correlation with their parents. Similarly, children who had dinner with their parents 'most times' but not 'sometimes,' had significant BMI correlation coefficients.
Parent-child resemblance in weight status was modest and varied by child age, gender, primary caregiver, whether having similar food or dinner with parents in China.
研究母子、父女、父子和父女在体重状况方面的相似性，以及社会人口学和儿童保育特征的潜在调节作用。
横断面研究。
学校。
2017 年来自中国五个特大城市的 1973 名学龄儿童及其父母。
父亲-儿子、父亲-女儿、母亲-儿子和母亲-女儿对 BMI 的皮尔逊相关系数（r）分别为 0.16、0.24、0.26 和 0.24，加权 kappa 系数（k）分别为 0.09、0.14、0.04 和 0.15。6-9 岁儿童（r 范围为 0.30-0.35）的 BMI 与父母的相关性大于 10-14 岁或 15-17 岁儿童（r 范围为 0.15-0.24）。与居住在学校/其他地方的儿童相比，居住在家中的儿童（r 范围为 0.17-0.27）与父母的 BMI 相关性更高。如果儿童主要由母亲照顾（r 范围为 0.17-0.29），则 BMI 相关系数显著，如果主要由其他人照顾，则不显著。只有当儿童“大多数时候”与父母一起吃饭（r 范围为 0.17-0.27）或“大多数时候”与父母一起吃晚餐（r 范围为 0.21-0.27）时，他们与父母的 BMI 才有显著相关性。同样，与父母一起吃晚餐“大多数时候”但“有时”不与父母一起吃晚餐的儿童，BMI 相关系数显著。
在中国，儿童的体重状况与父母的相似性适中，且因儿童年龄、性别、主要照顾者、是否与父母一起吃相似的食物或晚餐而有所不同。
