在一项前瞻性研究中，我们检查了怀孕前体重增加的预测因素，以及体重增加超过2009年医学研究所（IOM）基于怀孕前体重指数（BMI）的建议。数据来自一项基于人群的队列研究，共有1,420名妇女在基线和2年后接受了采访。分析样本包括103名基线时未怀孕并在随访期间分娩足月单胎的妇女。采用多元线性和Logistic回归分析，研究了孕前母亲体重类别以及健康行为、心理社会压力、产次和年龄作为妊娠体重增加和体重增加超过IOM建议的预测因素。怀孕期间体重平均增加33.01磅，51%的女性体重增加超过了2009年IOM对孕前体重类别的建议。孕前超重（BMI = 25-29.9）使妊娠期体重过度增加的几率增加了近三倍，而符合活动指南的孕前体力活动水平降低了体重过度增加的几率，但在统计学上并不显著。虽然未来的研究检查身体活动在怀孕体重增加的作用是必要的，孕前超重和身体活动水平是干预措施的主要目标，以避免过度怀孕体重增加。
We examined preconception (prepregnancy) predictors of pregnancy weight gain and weight gain that exceeds the 2009 Institute of Medicine (IOM) recommendations based on pre-pregnancy body mass index (BMI), in a prospective study. Data are from a population-based cohort study of 1,420 women who were interviewed at baseline and 2 years later. The analytic sample includes 103 women who were not pregnant at baseline and gave birth to full-term singletons during the follow-up period. Preconception maternal weight category as well as health behaviors, psychosocial stress, parity, and age were examined as predictors of pregnancy weight gain and of weight gain in excess of the IOM recommendations using multiple linear and logistic regression analysis. Pregnancy weight gain averaged 33.01 pounds, with 51% of women gaining weight in excess of the 2009 IOM recommendations for their preconception weight category. Preconception overweight (BMI = 25–29.9) increased the odds of excessive pregnancy weight gain nearly threefold, whereas preconception physical activity levels meeting activity guidelines reduced the odds of excessive weight gain but was marginally statistically significant. Although future research examining the role of physical activity in relation to pregnancy weight gain is needed, preconception overweight and physical activity levels are prime targets for interventions to avoid excessive pregnancy weight gain.
