Service acceptance of HIV non-occupational post-exposure prophylaxis(nPEP) among college students: a cross-sectional study in China

Background College students were the key group we should pay more attention for acquired immune deficiency syndrome (AIDS) prevention and control in recent years in China. Few studies of HIV non-occupational post-exposure prophylaxis (nPEP) knowledge and service acceptance had been conducted among them in China. This study conducted a cross-sectional survey to understand the service acceptance of nPEP and its influencing factors among college students in the three cities of China. Methods A questionnaire survey was conducted to collect information on socio-demographic, behavioral characteristic, HIV/AIDS knowledge, nPEP knowledge, acceptance of nPEP services among the college students in Beijing, Shenzhen, and Kunming of China from March to April of 2019. Each participant completed an anonymous questionnaire on line by computer-assisted or mobile phone-assisted self-interview with informed consent. Multivariable logistic regression analyses identified predictors for service acceptance of nPEP. Results A total of 4698 students were surveyed with the average age of 20 years old. 98.0% (4605/4698) of them were undergraduates, 21.8%(1022/4698) had sexual intercourse; 48.6% (2282/4698) heard of nPEP, among which 4.95%(113/2282) received nPEP services. The awareness rate of HIV/AIDS knowledge was 85.6% (5495/4698) with the differences statistically significant between the three cities. The awareness rate of nPEP knowledge was 16.5% (774/4698). There were significant differences in receiving nPEP services among students of different ages, genders, sexual behaviors, and knowledge of HIV/AIDS by univariate analysis. Multivariable analyses indicated that age group of 18 and under (OR = 2.551, 95% CI = 1.153-5.646), male (OR = 3.131, 95% CI = 1.866-5.253), homosexual behavior (OR = 4.661,95%CI = 2.658-8.172), heterosexual behavior (OR = 1.676, 95% CI = 1.040-2.947), no awareness of AIDS knowledge (OR = 3.882, 95% CI = 2.371-6.356) and nPEP (OR = 4.788, 95% CI = 2.50-9.169) knowledge, were associated with the service acceptance of nPEP among the college students. Conclusion The low acceptance of nPEP services was mainly affected by low level of nPEP knowledge among the college students. Further publicity and education of nPEP knowledge were necessary, as well as promotion of knowledge of HIV/AIDS prevention and treatment. More attention should be paid to the factors associated with acceptance of nPEP services. Keywords: HIV, AIDS, nPEP, college students, Sexual behavi
