Assessing parental marital quality and divorce related to youth sexual experiences and adverse reproductive health outcomes among 50,000 Chinese college students

Abstract

BackgroundThis study aimed to investigate the associations between parental marital quality, divorce, and sexual and reproductive health outcomes among Chinese young people.MethodsThe study included 51,124 students from a large-scale cross-sectional study in China from 2019 to 2020. The exposures were parental marital quality and legal marital status reported by students. The dichotomous outcomes included sexual experiences, high-risk sexual behaviors, unintended health outcomes, and sexual abuse. Multivariate logistic regression models adjusting for socio-demographic factors were used to assess the relationship between parental marital quality, divorce, and sexual and reproductive health outcomes, stratified by sex.ResultsA total of 10.72% of the surveyed students’ parents had divorced. Participants from divorced family rated perceived parental marital quality less than half of the ratings on a 10-point scale of those from intact family (3.22 vs. 7.44). Parental divorce was associated with a higher likelihood of sexual abuse, high-risk sexual behaviors, and unintended health outcomes. A higher perceived parental marital quality was associated with a lower probability of adverse sexual and reproductive health experiences and outcomes, such as forced penetrative vaginal or anal intercourse (male: OR: 0.73, 95% CI: 0.64–0.83; female: OR:0.71, 95% CI: 0.65–0.77), casual sexual intercourse (male: OR: 0.78, 95% CI: 0.73–0.83; female: OR: 0.77, 95% CI: 0.72–0.83), and sexually transmitted infections (male: OR: 0.79, 95% CI: 0.70–0.89; female: OR: 0.82, 95% CI: 0.73–0.91).ConclusionsParental marital quality and status are associated with poorer sexual and reproductive health outcomes among young adults, suggesting that specific intervention programs should be implemented for children from unharmonious families or divorced families to prevent adverse sexual and reproductive health outcomes.
