资中县农村留守与非留守中学生健康危险行为潜在类别分析

探讨潜在类别分析在四川省资中县农村青少年健康危险行为模式研究中的应用,为实施有针对性的干预提供科学依据.方法 采用“青少年健康相关行为调查问卷”对四川省资中县2所乡镇中学2 805名学生进行自填式问卷调查,应用潜在类别分析方法对8类健康危险行为进行分析.结果 留守青少年健康危险行为分为4类:高危险行为组有69人,占4%;高自我伤害和自杀行为组321人,占20%;中等危险行为组479人,占30%;低危险行为组727人,占46%.非留守青少年健康危险行为也分为4类:高危险行为组62人,占5%;高缺乏体育锻炼、自我伤害和自杀行为组78人,占6%;高意外伤害行为388人,占32%;低危险行为组681人,占56%.结论 留守与非留守青少年健康危险行为的潜在结构存在一定差异,高危险行为在留守和非留守青少年聚集方式不同,发生概率有差异.

Latent class analysis on health risk behaviors among left-behind and non-left-behind adolescents in rural area of Zizhong Country

Objective To compare health risk behavior patterns between left-behind and non-left-behind adolescents in rural area of Zizhang country,Sichuan province,by using latent class analysis(LCA),and to provide scientific basis for carrying out control stategies.Methods Totally 2 805 students from two middle schools in Zizhong county of Sichuan province were investigated with Health Risky Behavior Questionnaire for Adolescents.LCA was applied to analyze eight types of health risk behaviors.Results Four latent classes were observed among left-behind adolescents:69 adolescents of high-risk behavior group (4%),321 of high selfinjurious behavior and suicide(20%),479 of moderate health risk behavior (30%) and 727 of low-risk group(46%).Non-left-behind adolescents were also divided into four groups:62 of high-risk group (5%),78 of high physical inactivity,self-injurious and suicide group (6%),588 of high accidental injury group (32%) and 681 of low-risk group(56%).Conclusion There are obvious different health risk behavior patterns and the mode of assemblage between left-behind and non-left-behind adolescents.The probability of occurrence have differences.
