Adolescent health risk behaviors are a public health priority given their prevalence and their associations with chronic diseases and life quality in adulthood. This study examined the heterogeneity of adolescent health risk behaviors and the associations between demographic characteristics and subgroup membership in rural western China.
In fall 2015, 2805 students from rural middle schools in Sichuan Province were surveyed using the Health-Related Behavior Questionnaire for Adolescents. Latent class analysis (LCA) was used to identify subgroups of adolescents with distinct patterns of health risk behaviors. Differences in class membership related to selected demographic characteristics were examined using multinomial logistic regression analysis.
A four-class model emerged: (1) high-risk group (n = 108, 4.0%), (2) high-physical-inactivity and suicide-risk group (n = 340, 12.1%), (3) moderate-risk group (n = 897, 32.0%), and (4) low-risk group (n = 1460, 52.1%). The multinomial logistic regression analysis revealed that boys and adolescents with poor parental relationships and high allowances (spending money) were significantly more likely to be in the high-risk group than the low-risk group.
Adolescents in rural western China are a heterogeneous population requiring different tailored and effective interventions.
青少年健康危险行为是公共卫生的重点关注对象，因为其普遍存在且与成年后慢性病和生活质量有关。本研究旨在探讨中国西部农村青少年健康危险行为的异质性及其与人口统计学特征和亚组归属的关系。
2015 年秋季，采用青少年健康相关行为问卷对四川省农村中学的 2805 名学生进行了调查。采用潜在类别分析（LCA）识别具有不同健康危险行为模式的青少年亚组。使用多项逻辑回归分析检验与特定人口统计学特征相关的类别归属差异。
得出了一个四类别模型：（1）高风险组（n = 108，4.0%），（2）高身体活动不足和自杀风险组（n = 340，12.1%），（3）中风险组（n = 897，32.0%）和（4）低风险组（n = 1460，52.1%）。多项逻辑回归分析显示，男孩和与父母关系较差、零花钱较多的青少年比低风险组更有可能属于高风险组。
中国西部农村地区的青少年是一个异质化的群体，需要不同的、有针对性的有效干预措施。
