Factors Influencing Reproductive Health-Promoting Behaviors among Community-Dwelling Men in Their 20s

This study aimed to examine the associations among lifestyle factors, sexual knowledge, sexual attitudes, and reproductive health-promoting behaviors, and to identify factors influencing reproductive health-promoting behaviors among community-dwelling men in their 20s. This descriptive cross-sectional study involved an online survey of 149 men aged 20-29 residing in the southern Gyeonggi Province, South Korea. The study variables included lifestyle factors (smoking, alcohol consumption, physical activity, body mass index[BMI], and sleep disturbance), sexual knowledge, sexual attitudes, and reproductive health-promoting behaviors. Data were analyzed using descriptive statistics, correlation analysis, and multiple regression analysis. The results showed that reproductive health-promoting behaviors were negatively correlated with smoking and alcohol consumption frequency, and were also significantly correlated with the level of sleep disturbance. Multiple regression analysis revealed that smoking, alcohol consumption frequency, BMI, and sexual knowledge were significant factors influencing reproductive health-promoting behaviors, explaining 22.5% of the variance. These findings suggest that reproductive health promotion strategies for men in their 20s should adopt an integrated approach that enhances sexual knowledge alongside comprehensive lifestyle interventions, including smoking cessation, alcohol reduction, and weight management.
