Correlation analysis between adolescent cognitive ability and health risk behaviors

Abstract

Objective To explore the status of adolescents' health risk behaviors, relationship between cognitive ability and health risk behaviors, and provide an empirical reference for reducing the occurrence and early prevention of health risk behaviors among adolescents. Methods Samples were extracted by hierarchical, multi-stage, probability and scale proportional (PPS) methods. There were 112 schools randomly selected from 28 county-level regions (county, district, city), and 19 487 students were investigated by baseline survey, a follow-up study was conducted among 8 636 students during 2014-2015. Descriptive statistical methods of using 2 test and t test, and logistic multivariate regression analysis were used to analyze the relationship between cognitive abilities and healthy risk behaviors. Results The reported rate of a healthy risk behavior was 20.77%, and the incidence of more than one type of health risk behavior was 16.03%. The student’s cognitive ability standardized score was (0.33±0. 82). The average score of cognitive ability of adolescents with healthy risk behavior was 0.14, which was lower than the average score of cognitive ability of adolescents without healthy risk behaviors (0.43). Boys, having rural household registeration, non-residential schools, and parents with low education levels adolescents were more likely to be involved in health behavior risks. There was a significant correlation between adolescent cognitive ability and healthy risk behavior ( OR = 0.67, P <0.01). Conclusion The current status of adolescent health risk behaviors is worrying. The cognitive ability has a significant impact on health risk behaviors. It is recommended to use the cognitive ability of adolescents as a starting point to prevent and reduce the occurrence of adolescent health risk behaviors. 【摘要】目的 探究青少年健康危险行为现状及其与认知能力的关系，为减少青少年健康危险行为的发生及早期预 防提供实证参考。 方法 采用分层次、多阶段、概率与规模成比例（PPS)的方法，从全国28个县级单位（县、区、市）随机抽 取112所学校，2013—2014学年基线调査19 487名学生，2014—2015学年追踪调査8 636名初中学生。运用妒检验、《检 验的描述性统计方法，以及Logistic多因素回归分析认知能力与健康危险行为的关系。 结果 学生存在1种健康危险行为 的报告率为20.77%，1种以上的健康危险行为报告率为16.03%。学生认知能力标准化得分为（0.33±0.82)分。有健康危 险行为的青少年认知能力标准化得分均分为0.14分，没有健康危险行为青少年的得分为0.43分。男性、农村户口、非住 校、父母受教育程度低的青少年更容易发生健康危险行为。Logistic回归分析显示，青少年认知能力与其健康危险行为的 相关有统计学意义（ OR = 0.67， P <0.01)。 结论 青少年健康危险行为现状堪忧，认知能力对健康危险行为的影响显著。建 议以青少年的认知能力为出发点，预防和减少青少年健康危险行为的发生。
