Background The Democratic Republic of Congo (DRC) has experienced political unrest, civil insecurity, and military disputes, resulting in extreme poverty and a severely impaired health care system. To reduce the morbidity and mortality in women and children by strengthening healthcare, this study aimed at exploring the relationship between self-reported insecurity of mothers and maternal health-seeking behaviours and diseases in children in the DRC. Method Data collected from 8144 mothers and 14,403 children from the Multiple Indicators Cluster Survey (MICS) conducted by the National Institute of Statistics in 2017–2018, in collaboration with the United Nations Children’s Fund (UNICEF), was used. The severity of the conflict in different provinces was measured using the Uppsala Conflict Data Program (UCDP) reports. Multivariate logistic regression and stratified analysis were utilized to explore the association between conflicts with maternal health-seeking behaviours and diseases among children. Results High self-reported insecurity was positively associated with skilled antenatal care (OR1.93, 95%CI 1.50–2.49), skilled attendants at delivery (OR1.42, 95%CI 1.08–1.87), and early initiation of breastfeeding (OR1.32, 95%CI 1.04–1.68). These associations were more significant in regions with more armed conflict. It was also found that children of mothers with high self-reported insecurity were more likely to suffer from diarrhoea (OR1.47, 95%CI: 1.14–1.88), fever (OR1.23, 95%CI 1.01–1.50), cough (OR1.45, 95%CI 1.19–1.77), and dyspnea (OR2.04, 95%CI 1.52–2.73), than children of mothers with low self-reported insecurity. Conclusions Conflicts increases mothers’ insecurities and negatively affects children’s development. However, high conflict regions have to increase governmental and international assistance to promote the availability and access to maternal and child health services.

Background: This study aimed to investigate the associations between parental marital quality, divorce, and sexual and reproductive health outcomes among Chinese young people. Methods: The 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. Results: A 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). Conclusions: Parental 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.
