目的：近几十年来，肥胖在美国急剧增加。我们的目的是探讨美国妇女，年龄在20-44岁，与身体质量指数（BMI）和相关的协变量的避孕选择的协会研究设计：数据是基于对全国样本的11,300名妇女在2011-2015年全国家庭成长调查的访谈。我们分析了年龄在20-44岁的女性意外怀孕的风险。主要因变量为BMI类别。分析的协变量包括年龄、产次、种族/民族、婚姻状况、自我报告的健康状况和教育程度。通过交叉制表和逻辑回归分析数据。我们测定了三种避孕方法：女性绝育、宫内节育器（IUD）和激素避孕的未校正和校正比值比。（BMI 30.0-34.9 kg/m（2）：校正比值比（aOR）= 1.96，95%置信区间（CI）1.45-2.66; BMI 35.0 kg/m（2）及以上：aOR=1.56，95%CI 1.13-2.14）。BMI >35 kg/m2的妇女使用宫内节育器的几率显著较高（aOR=1.64，95%CI 1.20-2.25）。激素避孕药的使用几率相应降低（aOR=0.78，95%CI 0.62-0.98）的妇女在最高的BMI category.Conclusions：避孕药的使用不同的BMI类别，即使调整后通常的使用相关。在避孕药具使用的BMI类别的差异有影响避孕咨询和provision.Implications：调查结果表明，肥胖妇女更有可能依赖于女性绝育提出的问题，体重问题和肥胖如何影响避孕决策。未来的研究可以探索青春期女性肥胖与避孕药具使用之间的联系。(C)2017由Elsevier Inc.出版
Objective: Obesity has increased dramatically in the United States in recent decades. Our objective was to explore associations of contraceptive choices of US women, aged 20-44 years, with body mass index (BMI) and relevant covariates.Study design: Data are based on interviews with a national sample of 11,300 women in the 2011-2015 National Survey of Family Growth. We analyzed women ages 20-44 at risk of unintended pregnancy. The primary dependent variable was BMI category. Covariates analyzed included age, parity, race/ethnicity, marital status, self-reported health and education. Data were analyzed via cross-tabulation and logistic regression. We determined unadjusted and adjusted odds ratios for three categories of contraceptive method: female sterilization, intrauterine device (IUD) and hormonal contraception.Results: Obese women have higher odds of female sterilization (BMI 30.0-34.9 kg/m(2) : adjusted odds ratio (aOR) = 1.96, 95% confidence interval (CI) 1.45-2.66; BMI 35.0 kg/m(2) and higher: aOR=1.56, 95% CI 1.13-2.14) compared to women with normal BMI. Odds of IUD use are significantly higher among women with BMI >35 kg/m(2) (aOR=1.64, 95% CI 1.20-2.25). Odds of hormonal contraceptive use are correspondingly reduced (aOR=0.78, 95% CI 0.62-0.98) for women in the highest BMI category.Conclusions: Contraceptive use varies by BMI category even after adjusting for usual correlates of use. Differences in contraceptive use by BMI category have implications for contraceptive counseling and provision.Implications: Findings that obese women are more likely to rely on female sterilization raise questions about how weight concerns and obesity affect contraceptive decision making. Future research could explore associations between obesity and contraceptive use in adolescent women. (C) 2017 Published by Elsevier Inc.
