Condom use at sexual debut among Chinese youth

A Latent Class Analysis of Sexual Behavior and Associations with Sex Education, Smoking, Drinking, and Pornography Use Among Chinese Youth

The incidence of sexually transmitted diseases has alarmingly increased among Chinese youth in the past decade, and newly diagnosed cases of AIDS have almost doubled between 2010 and 2015. However, little is known about classes of sexual behavior among Chinese youth and associations with their other health behavior or experience of sex education. This study aimed to first identify classes of sexual behavior using latent class analysis and then to examine their associations with sex education, smoking, alcohol drinking, and pornography use. Data were from 13,865 unmarried youth aged 18-24 from the 2009 National Youth Reproductive Health Survey. Six indicators were used: timing of the first sexual intercourse, the number of past-year sexual partners, sex outside of a relationship, incidence of pregnancy, and contraceptive use at the latest and the first sexual intercourse. Four classes were identified: no sex (Class 1, 69%), safer sex (Class 2, 13%), early risk (Class 3, 13%), and multiple risk (Class 4, 5%). Smoking, drinking, and regular pornography use were associated with increased odds of being in the multiple risk class relative to the safer sex class. Sex education, smoking, and pornography use were associated with decreased odds of being in the no sex class relative to the safer sex class. The findings revealed qualitatively different classes of sexual behavior among Chinese youth and important roles of sex education, substance use, and pornography use. Reproductive health service providers can offer individually tailored services to serve youth with different profiles and needs.

Sexual debut among college students in China: effects of family context

This study examines family context and sexual debut among young people in China. Using data from the 2018 Panel Study of Chinese University Students (PSCUS), it explores how the family is correlated with sexual debut among young people in China aged 18-24 years. The Kaplan-Meier method was adopted to detect a survival function for different family factors and related demographic variables. Cox proportional hazard regression analysis was adopted to calculate hazard ratios for the timing of sexual debut. The average age of sexual debut among the college students was 18.39 years. The Kaplan-Meier analysis showed that sexual intercourse initiation was earlier for female students who had no siblings, and those who had a mother with senior high school (including technical school) education or higher family income, but this correlation was insignificant among male students. The multivariate hazard regression analysis revealed that living in a family with a higher level of fathers' education, having a lower level of family income and having siblings had positive correlations with later sexual debut among the college students. Moreover, family factors showed gender differences in their associations with the timing of sexual debut, typically parent's education level, family income and left-behind experience. This study provides a comprehensive perspective on the role of family influences in timing of sexual debut among youth in China.

HIV knowledge among male labor migrants in China

Background

This study described knowledge about HIV prevention and transmission among labor migrants in China and assessed the factors that associate with HIV knowledge.

Methods

The study is based on primary data collected in Xi’an city, China. The study includes 939 male rural-to-urban migrants aged 28 and older. The multivariate analysis used OLS regression techniques to examine the correlates of HIV knowledge.

Results

Most migrants know what AIDS/HIV is, but many have deficient knowledge about self-protection and the transmission routes of HIV. About 40% of migrants fail to understand that condoms decrease the risk of HIV infection. Higher levels of education and internet usage associate with better HIV knowledge. Migrants who have engaged in sex with commercial sex workers have better HIV knowledge than migrants who have never paid for sex. This includes better knowledge of self-protection.

Conclusion

Labor migrants are a high risk population for HIV infection. Their lack of HIV knowledge is a serious concern because they are a vulnerable group for infection and their sexual behaviors are spreading HIV to other members of the population and across geographic areas.
