目的：确定在医学研究所建议的孕期体重增加之外影响风险的因素，并确定这些因素是否因种族而异。方法：采用多变量方法确定1987-1989年期间在约翰霍普金斯医院分娩的2617名黑人和1253名白人妇女的妊娠不足和妊娠过度的危险因素。结果：只有28.2%的黑人妇女和32.5%的白人妇女在怀孕期间增加了推荐的体重。孕妇孕前体重指数（BMI）、身高、胎次、受教育程度、吸烟、高血压、怀孕持续时间和胎儿性别影响体重不足或体重超标的风险。黑人女性比白人女性低1.51倍（95%可信区间[CI] 1.23-1.85），但比白人女性低0.89倍（95%可信区间[CI] 0.74-1.08）。没有发现任何因素与BMI或种族之间的相互作用。结论：只有大约三分之一的女性在怀孕期间体重达到了建议的水平。黑人女性体重增加的风险低于推荐值，而与种族相关的特定母亲特征并不能解释这种差异。此外，黑人妇女和白人妇女的增肥不足或过多的危险因素并无不同。
Objectives: To identify factors influencing risk of gaining outside the Institute of Medicine recommendations for pregnancy weight gain, and to determine whether these factors differ by race.Methods: Multivariate methods were used to identify risk factors for under- and over-gain among 2617 black and 1253 white women delivering at the Johns Hopkins Hospital during 1987-1989.Results: Only 28.2% of black women and 32.5% of white women gained the recommended amounts of weight during pregnancy. Maternal pre-pregnancy body mass index (BMI), height, parity, education, smoking, hypertension, duration of pregnancy, and fetal sex influenced risk for under-gain or over-gain. Black women were 1.51 (95% confidence interval [CI] 1.23-1.85) times more likely to under-gain, but 0.89 (95% CI 0.74-1.08) times less likely to over-gain than white women. No interactions were found between any factor examined and BMI or race.Conclusion: Only about one-third of women are gaining the recommended amounts of weight during pregnancy. Black women are at increased risk for gaining less weight than recommended, and selected maternal characteristics associated with race do not explain this difference. Further, risk factors for under- or over-gain do not differ between black and white women.
