We evaluated the association between parental obesity and their children's obesity parameters [e.g., percentage of body fat (PBF)] over time.
The study included 2066 Chinese parents-children trios (n = 1001 girls and 1065 boys, aged 6-14 years). Children's height, weight, waist circumference (WC) and PBF (bioelectrical impedance analysis) were annually assessed from 2014 (baseline) to 2016. Information on parental height and body weight, and children's diet and physical activity was collected in 2014. The association between parental obesity and changes in their children's PBF during follow-up was analyzed using a mixed effects model. We also examined changes in children's BMI and WC in secondary analyses. Baseline mean BMI, WC, and PBF for children were 17.6 ± 3.5 kg/m, 60.5 ± 9.6 cm, and 16.6 ± 6.5%, respectively. We observed that maternal, but not paternal, obesity was associated with a greater increase in children's PBF during the follow-up. An adjusted mean difference in annual increase of PBF was 0.41% [95% confidence interval (CI): 0.01%, 0.84%] for children with obese mothers, compared with those with normal-weight mothers. Both maternal and paternal obesity was associated with a greater increase in their children's BMI and WC (p trend<0.01 for both); however, the associations were stronger in mother-children pairs than those in father-children pairs.
Maternal obesity was associated with a greater increase in PBF in Chinese school-aged children.
我们评估了父母肥胖与他们孩子肥胖参数（例如体脂肪百分比 [PBF]）随时间的变化关系。
本研究纳入了 2066 对中国父母-子女三人组（n = 1001 名女孩和 1065 名男孩，年龄 6-14 岁）。从 2014 年（基线）到 2016 年，每年评估儿童的身高、体重、腰围（WC）和 PBF（生物电阻抗分析）。2014 年收集了父母身高和体重、儿童饮食和身体活动的信息。使用混合效应模型分析了父母肥胖与随访期间儿童 PBF 变化之间的关系。我们还在二次分析中检查了儿童 BMI 和 WC 的变化。儿童基线时的平均 BMI、WC 和 PBF 分别为 17.6 ± 3.5 kg/m、60.5 ± 9.6 cm 和 16.6 ± 6.5%。我们发现，母亲肥胖，但不是父亲肥胖，与随访期间儿童 PBF 的增加更为相关。与母亲体重正常的儿童相比，肥胖母亲的儿童 PBF 年增长率的调整平均差异为 0.41%（95%可信区间：0.01%，0.84%）。母亲和父亲肥胖均与儿童 BMI 和 WC 的增加有关（p 趋势<0.01）；然而，母亲-子女对子的关联比父亲-子女对子更强。
母亲肥胖与中国学龄儿童 PBF 的增加有关。
