This study involved 330 primiparous Black adolescents. The purpose of the study was to examine predictors of body mass index (BMI) change in Black adolescents 6 and 9 years after they gave birth. Predictors were gestational weight gain, pre-pregnant BMI, and age (p < .001). For older adolescents (ages 18-19), gestational weight gain was the only predictor of BMI change (p = .008). Regardless of pre-pregnant BMI category, adolescents whose gestational weight gain exceeded Institute of Medicine (IOM) recommendations were 4.6 times more likely to be obese than those whose weight gain was within recommendations. Excessive gestational weight gain and pre-pregnant overweight contribute to adolescent obesity. These findings have implications from both a clinical and public health perspective.
本研究纳入了330名初产黑人青少年。该研究的目的是调查黑人青少年产后6年和9年时体重指数（BMI）变化的预测因素。预测因素包括孕期体重增加、孕前BMI和年龄（p < .001）。对于年龄较大的青少年（18 - 19岁），孕期体重增加是BMI变化的唯一预测因素（p = .008）。无论孕前BMI类别如何，孕期体重增加超过医学研究所（IOM）建议的青少年肥胖的可能性是体重增加在建议范围内的青少年的4.6倍。孕期体重过度增加和孕前超重会导致青少年肥胖。这些发现从临床和公共卫生角度都具有重要意义。
