condom use during sexual intercourse in a nationally representative sample of women and men aged 15-44 in the United States using the 2011-2015 National Survey of Family Growth (NSFG). Where data were available, patterns of condom use during sexual intercourse from the 2011-2015 NSFG were compared with the 2002 and 2006-2010 NSFG. Methods-Data were collected through in-person interviews with nationally representative, independent samples of women and men aged 15-44 in the household population of the United States. Interviews were conducted between September 2011 and September 2015 with 11,300 women and 9,321 men. The response rates for the 2011-2015 NSFG were 72.3% for women and 69.6% for men aged 15-44. Results-During 2011-2015, 23.8% of women and 33.7% of men aged 15-44 used a condom at last sexual intercourse in the past 12 months, an increase for men since 2002 (29.5%). Among condom users, 59.9% of women and 56.4% of men aged 15-44 used only a condom and no other method during last intercourse in the past 12 months; another 25.0% of women and 33.2% of men used condoms plus hormonal methods; and 15.1% of women and 10.5% of men used condoms plus nonhormonal methods. During any intercourse in the past 4 weeks, 18.2% of women and 23.9% of men aged 15-44 used a condom "100%" of the time. The prevalence of condom use during any intercourse in the past 4 weeks varied by age, education, Hispanic origin and race, relationship at last sexual intercourse, and number of opposite-sex sexual partners in the past 12 months. Almost 7% of women aged 15-44 who used a condom in the past 4 weeks said the condom broke or completely fell off during intercourse or withdrawal, and 25.8% said the condom was used for only part of the time during intercourse.
使用2011 - 2015年全国家庭成长调查（NSFG）对美国15 - 44岁具有全国代表性的男女样本进行性交时避孕套使用情况的研究。在数据可得的情况下，将2011 - 2015年NSFG中性交时避孕套使用模式与2002年以及2006 - 2010年NSFG进行比较。方法——通过对美国家庭人口中15 - 44岁具有全国代表性的独立男女样本进行面对面访谈来收集数据。访谈于2011年9月至2015年9月期间进行，共访谈了11300名女性和9321名男性。2011 - 2015年NSFG中15 - 44岁女性的回应率为72.3%，男性为69.6%。结果——在2011 - 2015年期间，15 - 44岁的女性中有23.8%、男性中有33.7%在过去12个月的最后一次性交时使用了避孕套，男性自2002年以来这一比例有所上升（29.5%）。在避孕套使用者中，15 - 44岁的女性中有59.9%、男性中有56.4%在过去12个月的最后一次性交时仅使用了避孕套而未使用其他方法；另外，25.0%的女性和33.2%的男性使用了避孕套加激素方法；15.1%的女性和10.5%的男性使用了避孕套加非激素方法。在过去4周的任何一次性交中，15 - 44岁的女性中有18.2%、男性中有23.9%“每次”都使用了避孕套。过去4周内任何一次性交时避孕套的使用 prevalence因年龄、教育程度、西班牙裔血统和种族、最后一次性交时的关系以及过去12个月内异性性伴侣数量而异。在过去4周内使用过避孕套的15 - 44岁女性中，近7%表示避孕套在性交或抽出时破裂或完全脱落，25.8%表示避孕套仅在性交的部分时间使用。 （注：原文中“prevalence”未翻译完整，可能是有遗漏信息，这里保留英文以便你核对原文）
