<![CDATA[Risky sexual behavior among adolescents is a public health concern influenced by cognitive and religious factors. This study aimed to analyze the relationship between reproductive health understanding and religious values with adolescent risky sexual behavior and examine the moderating role of religious values. This quantitative analytical study employed a cross-sectional design involving 120 adolescents aged 15–18 years selected through simple random sampling. Data were collected using structured self-administered questionnaires and analyzed using Spearman’s Rank correlation and Moderated Regression Analysis (MRA). The results showed that most respondents had moderate reproductive health understanding (42.5%), high religiosity (51.7%), and low-risk sexual behavior (61.7%). Reproductive health understanding was significantly negatively correlated with risky sexual behavior (rs = -0.412); (p < 0.001). Religious values also demonstrated a significant negative correlation with risky sexual behavior (rs = -0.485); (p < 0.001). MRA confirmed that religious values significantly moderated the relationship between reproductive health understanding and risky sexual behavior (b = -0.318); (p = 0.002), increasing the coefficient of determination (R2) to 46.1%. These findings indicate that reproductive health understanding and religious values may jointly serve as protective factors against risky sexual behavior among adolescents. Integrating evidence-based reproductive health education with religious and moral values may provide a comprehensive approach to adolescent sexual health promotion and risk prevention.]]>
