: To provide protection against sexually transmitted infections and pregnancy, condoms must be used consistently and correctly. However, a significant proportion of couples in the United States fail to do so. Our objective was to determine the demographic and behavioral correlates of inconsistent and incorrect condom use among sexually active, condom-using women.
: Analysis of baseline data from a prospective cohort of sexually active, condom-using women in the Contraceptive CHOICE Project (n = 2087) using self-reported demographic and behavioral characteristics. Poisson regression was used to determine the relative risk of inconsistent and incorrect condom use after adjusting for variables significant in the univariate analysis.
: Inconsistent and incorrect condom use was reported by 41% (n = 847) and 36% (n = 757) of women, respectively. A greater number of unprotected acts was most strongly associated with reporting 10 or more sex acts in the past 30 days, younger age at first intercourse, less perceived partner willingness to use condoms, and lower condom use self-efficacy. Incorrect condom use was associated with reporting 10 or more sex acts in the past 30 days, greater perceived risk for future STIs, and inconsistent condom use.
: Inconsistent and incorrect condom use is common among sexually active women. Targeted educational efforts and prevention strategies should be implemented among women at highest risk for STIs and unintended pregnancies to increase consistent and correct condom use.
为了预防性传播感染和妊娠，必须正确且持续地使用避孕套。然而，美国相当一部分夫妇并未做到这一点。我们的目的是确定性行为活跃且使用避孕套的女性中，避孕套使用不当和不规律的相关人口学和行为因素。
使用自我报告的人口统计学和行为特征，对避孕选择项目（Contraceptive CHOICE Project）中 2087 名性行为活跃且使用避孕套的女性的基线数据进行分析。采用泊松回归分析，在单变量分析中具有显著意义的变量进行调整后，确定避孕套使用不当和不规律的相对风险。
分别有 41%（n=847）和 36%（n=757）的女性报告了避孕套使用不当和不规律。与报告过去 30 天内有 10 次或更多性行为、初次性行为年龄较小、较少感知到伴侣愿意使用避孕套、以及较低的避孕套使用自我效能感相比，未使用保护措施的性行为更多，与报告避孕套使用不当和不规律的关联性更强。避孕套使用不当与报告过去 30 天内有 10 次或更多性行为、对未来性传播感染的风险感知更大，以及避孕套使用不规律有关。
性行为活跃的女性中，避孕套使用不当和不规律的情况较为常见。应针对性传播感染和意外怀孕风险最高的女性实施有针对性的教育和预防策略，以增加避孕套的正确且持续使用。
