目的：探讨孕期超重和产后6个月内超重对8~10年后超重的影响。方法：对795名孕妇在孕期和产后6个月进行观察，分析影响超重的因素。10年后，通过一项医疗记录审查记录体重，以检查保留体重对长期肥胖的影响。最后一次随访时的总体体重变化和体重指数(BMI)根据美国医学研究所关于孕期体重增加的指南检查了孕期体重增加的适宜性。结果：在最初的队列中，540名女性的记录体重超过5年(平均=8.5年)。从孕前到随访，平均体重增加了6.3公斤。孕前BMI对体重增加没有影响。怀孕期间体重增加低于推荐量的女性在随访时体重增加4.1公斤，达到推荐量的女性体重增加6.5公斤，超过推荐量的女性体重增加8.4公斤(P=0.01)。产后6个月所有妊娠体重减轻的妇女在随访时比保留体重的妇女重2.4公斤，后者在随访时多重8.3公斤(P=.01)。母乳喂养的女性和参加有氧运动的女性的体重增长也明显较低，结论：超重和怀孕后未能减肥是长期肥胖的重要和可识别的预测因素。母乳喂养和锻炼可能有利于控制长期体重。(C)2002年，由美国妇产科医师学会提供。
OBJECTIVE: To estimate the impact of excess pregnancy weight gain and failure to lose weight by 6 months postpartum on excess weight 8-10 years later.METHODS: Seven hundred ninety-five women were observed through pregnancy and 6 months postpartum to examine factors that affect weight loss. Weight was recorded 10 years later through a medical record review to examine the impact of retained weight on long-term obesity. Overall weight change at last follow-up and body mass index (BMI) were examined by pregnancy weight gain appropriateness according to the Institute of Medicine guidelines for weight gain during pregnancy.RESULTS: Of the original cohort, 540 women had a documented weight beyond 5 years (mean = 8.5 years). The average weight gain from prepregnancy to follow-up was 6.3 kg. There was no difference in weight gain by prepregnancy BMI. Women who gained less than the recommended amount during their pregnancy were 4.1 kg heavier at follow-up, those gaining the recommended amount were 6.5 kg heavier, and those gaining more than recommended were 8.4 kg heavier (P = .01). Women who lost all pregnancy weight by 6 months postpartum were 2.4 kg heavier at follow-up than women with retained weight, who weighed 8.3 kg more at follow-up (P = .01). Women who breast-fed and women who participated in aerobic exercise also had significantly lower weight gains,CONCLUSION: Excess weight gain and failure to lose weight after pregnancy are important and identifiable predictors of long-term obesity. Breast-feeding and exercise may be beneficial to control long-term weight. (C) 2002 by The American College of Obstetricians and Gynecologists.
