Factors associated with risk sexual behaviours of HIV/STDs infection among university students in Henan, China: a cross-sectional study

摘要

This study aimed to identify factors associated with risk sexual behaviours and target high-risk groups at risk of HIV/STDs infection among university students. The cross-sectional study was conducted from 1 November to 31 December 2020 in one university, located in Henan Province. A total of 1602 individuals who reported having?ever had sex were analyzed as the subjects of this study. Descriptive analysis and multivariable logistic regression analysis were applied for this study to assess factors associated with risk sexual behaviours among university students. University students who reported having?ever had sex accounted for about 9%, with an average age of 19.37?±?1.03. Of them, having multiple sexual partners and inconsistent condom use during the last 6?months were 37.3% and 35%, respectively. Over 50% of participants had their sexual debut before the age of 18. Bisexual students (AOR?=?0.27; 95% CI 0.16, 0.44) and those who lived on over 3000 Yuan per month (AOR?=?0.50; 95% CI 0.28, 0.91) were consistently less likely to engage in condom use during the last 6?months. University students who were?from high-grade (AOR?=?1.56; 95% CI 1.12, 2.18 for sophomore; AOR?=?1.84; 95% CI 1.28, 2.65 for junior; AOR?=?2.07; 95% CI 1.38, 3.11 for senior), who lived on over 3,000 Yuan per month (AOR?=?4.19; 95% CI 2.17, 8.11)?or who reported being homosexual (AOR?=?3.92; 95% CI 2.17, 7.06) and bisexual (AOR?=?33.22; 95% CI 13.11, 84.15)?were more likely to have?multiple sexual relationships. University students who had sexual debut before the age of 18 were more likely to engage in risk sexual behaviours. The prevalence of sexual activity among Chinese university students is generally low, but risk sexual behaviours are of considerable concern. University students with higher living expenses, who are not heterosexual?and who are?younger at first sexual intercourse tend to engage in risk sexual behaviours. The scale-up of intervention is the need to prevent the expansion of the HIV epidemic among young students. The HIV epidemic among university students is considerable, with the tendency of the high-risk population towards the general population. University students at risk of HIV/STDs infection tend to engage in risk sexual behaviours?and were targeted for assessing factors corelated with their risk sexual behaviours?in this study. Participants who reported having had?sexual relations were selected. Information on the practice of risk sexual behaviours including multiple sexual partners and inconsistent condom use were collected and analyzed using a multivariable logistic regression model. Bisexual students were consistently less likely to use condoms within the last 6?months. University students from high-grade, who lived on over 3000 Yuan monthly, homosexual students?and bisexual students?were?more likely to have?multiple sexual relationships. University students who had sexual debut before the age of 18 were more likely to engage in risk sexual behaviours. In conclusion, University students with high cost of living per month, non-heterosexual, who are younger at first sexual intercourse tend to engage in risk sexual behaviours. Intensified intervention is the need to prevent the expansion of the HIV epidemic amongst young students.
