Establishing the discriminative factors for unprotected sex among adolescents is essential for early identification of at-risk teens and for the prevention of unplanned pregnancy and sexually transmitted diseases. The aim of this study was to examine the discriminative effects of demographic, individual, family, peers, and school life factors on unprotected sex in a large-scale, representative adolescent population in Southern Taiwan. A total of 9,736 adolescent students were recruited into this study and completed the questionnaires. The multidimensional discriminative factors for unprotected sex were examined using chi2 automatic interaction detection analysis and logistic regression models. The results of the chi2 automatic interaction detection analysis revealed that having friends, using illicit drugs, being of an older age, suspension from school, and low family monitoring had discriminative effects on unprotected sex in adolescents. The logistic regression analysis further confirmed the discriminative effect of these factors. Because of the adverse effects of unprotected sex in adolescents, we suggest that parents and health professionals should pay attention to adolescents with the discriminative factors for unprotected sex identified in this study.
确定青少年无保护性行为的判别因素对于早期识别高危青少年以及预防意外怀孕和性传播疾病至关重要。本研究旨在探讨人口统计学、个体、家庭、同伴和学校生活因素对台湾南部大规模代表性青少年人群无保护性行为的判别效应。共有 9736 名青少年学生参与了这项研究，并完成了问卷调查。使用卡方自动交互检测分析和逻辑回归模型来检验无保护性行为的多维判别因素。卡方自动交互检测分析的结果表明，有朋友、使用非法药物、年龄较大、被学校停学和家庭监督不力对青少年的无保护性行为有判别作用。逻辑回归分析进一步证实了这些因素的判别作用。由于青少年无保护性行为的不良影响，我们建议家长和卫生专业人员应关注本研究中确定的具有无保护性行为判别因素的青少年。
