Childhood obesity is potentially affected by breastfeeding, parents' body mass index and birth weight. Thus, this study aimed to verify the association between breastfeeding, parents' body mass index and birth weight with obesity indicators in children.
This is a cross-sectional study, including data from 402 schoolchildren between 9 and 11 of age in the city of São Caetano do Sul, Brazil. Parents or guardians answered a questionnaire about breastfeeding (month), birth weight (kg), and parental body weight and height (parents' body mass index [kg/m] was calculated). Body mass index (kg/m), waist circumference (cm) and body fat (%), determined via bio-impedance, were measured and used as obesity indicators. Multi-level linear regression models were used to assess the respective associations adjusted for the potential confounders.
Considering body mass index of children, the overall prevalence of eutrophic, overweight and obese were 58.2%, 20.9% and 17.2%, respectively. Significant and positive correlations were observed between breastfeeding, maternal as well as paternal body mass index and the children's body mass index, body fat and waist circumference. Birth weight was weakly and positively associated with body mass index and body fat but was not associated with waist circumference. After adjusting for school, sex, age, race/ethnicity, annual household income, sedentary time and moderate-to-vigorous physical activity, maternal body mass index and birth weight were positively associated with children's body mass index (β: 0.228; 95%CI: 0.142; 0.314 and β: 0.001; 95%CI: 0.001; 0.002), body fat (β: 0.484; 95%CI: 0.297; 0.671 and β: 0.002; 95%CI: 0.001; 0.003) and waist circumference (β: 0.509; 95%CI: 0.304; 0.715 and β: 0.003; 95%CI: 0.001; 0.005). Breastfeeding was not associated with any obesity indicators.
Maternal body mass index and birth weight were associated with children's obesity indicators. The perinatal environment, therefore, appears to be a critical contributor to childhood obesity and public policies need to address parental obesity in order to tackle childhood obesity.

儿童肥胖可能受到母乳喂养、父母体重指数和出生体重的影响。因此，本研究旨在验证母乳喂养、父母体重指数和出生体重与儿童肥胖指标之间的关联。
这是一项横断面研究，纳入了巴西圣卡塔琳娜州 402 名 9-11 岁学龄儿童的数据。父母或监护人回答了有关母乳喂养（月）、出生体重（kg）和父母体重及身高（父母体重指数[kg/m]计算得出）的问卷。通过生物阻抗法测量了体重指数（kg/m）、腰围（cm）和体脂（%），并将其作为肥胖指标。采用多水平线性回归模型，在调整了潜在混杂因素后，评估了各变量之间的关联。
考虑到儿童的体重指数，肥胖的总体流行率分别为：营养良好、超重和肥胖，分别为 58.2%、20.9%和 17.2%。母乳喂养、母亲和父亲的体重指数与儿童的体重指数、体脂和腰围之间存在显著的正相关关系。出生体重与体重指数和体脂呈弱正相关，但与腰围无关。在校正了学校、性别、年龄、种族/民族、家庭年收入、久坐时间和中高强度体力活动后，母亲体重指数和出生体重与儿童体重指数（β：0.228；95%CI：0.142；0.314 和β：0.001；95%CI：0.001；0.002）、体脂（β：0.484；95%CI：0.297；0.671 和β：0.002；95%CI：0.001；0.003）和腰围（β：0.509；95%CI：0.304；0.715 和β：0.003；95%CI：0.001；0.005）呈正相关。母乳喂养与任何肥胖指标均无关联。
母亲体重指数和出生体重与儿童肥胖指标相关。因此，围产期环境似乎是儿童肥胖的一个关键因素，公共政策需要解决父母肥胖问题，以解决儿童肥胖问题。
