Among South African university students, HIV prevalence is lower than in age-peers, but at 3.8% it is not negligible. We examined prevalence of factors potentially associated with HIV risk, focusing on partnership characteristics and consistent condom use. We hypothesised that contraceptive-related factors, for example, desire to prevent pregnancy and not using hormonal contraceptives, would be positively associated with consistent condom use. Data were drawn from a representative interviewer-administered survey of 2nd to 4th year students conducted during registration at a university campus in KwaZulu-Natal. Of 576 students, 218 (83 women, 135 men) reported vaginal intercourse in the past 2 months. Of these, 7% of women and 43% of men reported past-year concurrent partnerships, and 24% knew/ suspected partner non-monogamy. Although reported condom use at last intercourse was 90%, 2-month consistent use was 53% (women) and 73% (men). Reported hormonal contraception use was low (women: 36.8%; men: 16.7%), and 68% used condoms for dual protection. In gender-stratified multivariable analyses, consistent condom use was higher for men who reported their partner did not use (vs. used) hormonal contraception (aOR = 5.84; 95%CI = 2.71, 12.57; p < 0.001) and who reported using condoms for dual protection (vs. single protection) (aOR = 2.46; 95%CI = 1.43, 4.25; p = 0.001). No contraception-related factors were associated with consistent condom use among women. Sexual partnership characteristics potentially place sexually active university students at high HIV risk and should be investigated further. Among men, but not women, contraceptive concerns were associated with consistent condom use. Promoting condoms for dual protection may resonate with students and should be continued.
在南非大学生中,艾滋病毒感染率低于同龄人,但3.8%的感染率也不容忽视。我们研究了可能与艾滋病毒风险相关的因素,重点关注性伴侣关系特征和坚持使用避孕套的情况。我们假设与避孕相关的因素,例如预防怀孕的意愿以及不使用激素避孕方法,会与坚持使用避孕套呈正相关。数据来自于在夸祖鲁 - 纳塔尔省一个大学校园注册期间对二至四年级学生进行的一项由访员实施的代表性调查。在576名学生中,218名(83名女性,135名男性)报告在过去两个月内有过阴道性交。其中,7%的女性和43%的男性报告过去一年有多个性伴侣,24%的人知道/怀疑伴侣有非一夫一妻制行为。尽管报告在最近一次性交时使用避孕套的比例为90%,但在两个月内坚持使用避孕套的比例女性为53%,男性为73%。报告使用激素避孕方法的比例较低(女性:36.8%;男性:16.7%),68%的人使用避孕套进行双重保护。在按性别分层的多变量分析中,报告伴侣未使用(与使用)激素避孕方法的男性坚持使用避孕套的比例更高(调整后的比值比 = 5.84;95%置信区间 = 2.71, 12.57;p < 0.001),报告使用避孕套进行双重保护(与单一保护)的男性也是如此(调整后的比值比 = 2.46;95%置信区间 = 1.43, 4.25;p = 0.001)。在女性中,没有与避孕相关的因素与坚持使用避孕套有关。性伴侣关系特征可能使性活跃的大学生面临较高的艾滋病毒感染风险,应进一步进行调查。在男性而非女性中,避孕问题与坚持使用避孕套有关。推广避孕套进行双重保护可能会引起学生的共鸣,应继续进行。
