Assessing Students’ Knowledge and Attitudes Regarding the Risks and Prevention of Consanguineous Marriage: A Cross-Sectional Online Survey

Abstract

Background: Several studies indicate a correlation between consanguinity and genetic disorders, congenital malformations, harm to reproductive health, and increased child mortality. Objective: To assess students’ knowledge and attitudes about risks and prevention of consanguineous marriage. Methods: Demographic details of the participants and data on knowledge and attitudes concerning the risks and prevention of consanguineous marriage were obtained using an online self-administered questionnaire. The factors associated with good knowledge and attitude toward consanguineous marriage were investigated by logistic regression analysis. Results: A total of 667 participants enrolled in the study. The average knowledge score about consanguineous marriage risk and prevention was 78.6% with a 95% confidence interval (CI) [77.3, 79.8], and the average attitude was 79.7% with a 95% confidence interval (CI) [79, 80.6]. A better knowledge score was observed in older participants (OR 1.01; 95% CI 1.004–1.024), females (OR 1.69; 95% CI 1.48–1.94), participants with parental history of consanguinity (OR 1.33; 95% CI 1.17–1.52), participants with family history of consanguineous marriage (OR 5.18; 95% CI 2.19–7.10), and participants with family history of inherited disease (OR 1.52; 95% CI 1.25–1.86). Conclusion: In general, the overall level of knowledge and attitudes toward consanguineous marriage risk and prevention was good among university students. To efficiently control and manage the adverse health impacts associated with consanguineous marriage, there is an urgent need to develop and implement evidence-based counseling and screening programs for consanguineous marriage that would significantly reduce the number of at-risk marriages.
