To describe actual and preferred contraceptive sources among young people in Britain and whether discordance between these is associated with markers of sexual risk behaviour or poor sexual health.
Cross-sectional probability sample survey.
British general population.
3869 men and women aged 16-24 years interviewed for the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3) between 2010 and 2012.
Reported source of contraceptive method(s) and preferred source if all were available and easily accessible.
Of the 75% of young people (aged 16-24) who were heterosexually active (1619 women, 1233 men), >86% reported obtaining contraceptives in the past year. Most common sources were general practice (women, 63%) and retail (men, 60%): using multiple sources was common (women 40%, men 45%). Healthcare sources were preferred by 81% of women and 57% of men. Overall, 32% of women and 39% of men had not used their preferred source. This discordance was most common among men who preferred general practice (69%) and women who preferred retail (52%). Likelihood of discordance was higher among women who usually used a less effective contraceptive method or had an abortion. It was less likely among men who usually used a less effective method of contraception and men who were not in a steady relationship.
Most young people in Britain obtained contraception in the past year but one-third had not used their preferred source. Healthcare sources were preferred. Discordance was associated with using less effective contraception and abortion among young women. Meeting young people's preference for obtaining contraception from healthcare sources could improve uptake of effective contraception to reduce unwanted pregnancies.
描述英国年轻人实际使用的和首选的避孕方式来源，以及二者之间的不一致是否与性风险行为指标或不良性健康状况相关。
横断面概率抽样调查。
英国普通人群。
2010年至2012年期间，对3869名年龄在16 - 24岁的男性和女性进行了第三次全国性态度和生活方式调查（Natsal - 3）。
报告的避孕方法来源，以及如果所有来源都可得且易于获取时的首选来源。
在75%有异性性行为的16 - 24岁年轻人（1619名女性，1233名男性）中，超过86%的人报告在过去一年中获取过避孕药具。最常见的来源是全科医疗（女性为63%）和零售渠道（男性为60%）：使用多种来源很常见（女性为40%，男性为45%）。81%的女性和57%的男性更喜欢医疗保健来源。总体而言，32%的女性和39%的男性未使用他们首选的来源。这种不一致在首选全科医疗的男性（69%）和首选零售渠道的女性（52%）中最为常见。在通常使用效果较差的避孕方法或做过人工流产的女性中，不一致的可能性更高。在通常使用效果较差的避孕方法的男性以及没有稳定恋爱关系的男性中，这种可能性较低。
英国大多数年轻人在过去一年中获取过避孕药具，但三分之一的人未使用他们首选的来源。医疗保健来源更受青睐。不一致与年轻女性使用效果较差的避孕方法和人工流产有关。满足年轻人从医疗保健来源获取避孕药具的偏好，可能会提高有效避孕措施的使用率，以减少意外怀孕。
