The purpose of this study was to assess the independent effects of the prenatal environment and cumulated social risks on the likelihood of being overweight at age 12/13 years. Maternal prepregnancy weight and smoking during pregnancy were the measures of prenatal exposures. Average lifetime per capita income and mother's lifetime marital status were the measures of cumulative social risks. Analysis of data from the National Longitudinal Survey of Youth's Child-Mother file indicated that exposures to tobacco smoke in utero, maternal prepregnancy overweight/obesity, and maternal unmarried status were significant risks for adolescent overweight. The risk for overweight was reduced by breastfeeding if the mother was overweight/obese prepregnancy. Prenatal and early life factors were related to adolescent overweight, providing an important window for intervention.
本研究的目的是评估产前环境和累积社会风险对12/13岁时超重可能性的独立影响。孕前体重和孕期吸烟是产前暴露的衡量指标。平均终身人均收入和母亲的终身婚姻状况是累积社会风险的衡量指标。对全国青年纵向调查的儿童-母亲档案数据的分析表明，子宫内接触烟草烟雾、孕前超重/肥胖以及母亲未婚状态是青少年超重的重大风险因素。如果母亲孕前超重/肥胖，母乳喂养可降低超重风险。产前和早年因素与青少年超重有关，这为干预提供了一个重要窗口。
