Multiple correspondence analysis of the influencing factors of injury among left-behind primary school students in Pingliang

Abstract

Objective To explore the distribution characteristics of the influencing factors of injury among left-behind primary school students, so as to provide a reference for identifying high-risk injury groups and carrying out accurate injury intervention.

Methods From August 2021 to July 2022, a questionnaire survey was conducted among 3 769 students from grades 4 to 6 from nine primary schools in three townships in Pingliang City by using the a random cluster sampling method. Multiple correspondence analysis was used to analyze the influencing factors of injury.

Results The detection rate of injuries among non-left-behind pupils was 21.8% (573/2 631), whereas the detection rate of injuries among left-behind pupils was 40.9% (466/1 138). In addition, a statistically significant difference was observed in the detection rate of injuries between left-behind pupils and non-left-behind pupils (χ ² = 146.21, P<0.01). Among the injuries of left-behind pupils, 263 had fall-related injuries, accounting for the highest proportion (56.4%). Whether it was an only child, and different grades, gender, personality, psychological status, monitoring type, and maternal education level were statistically significant (χ ²=39.05, 96.69, 143.00, 155.80, 461.39, 285.35, 17.10, P<0.01). The multiple correspondence analysis category graph showed higher rates of fall injuries, blunt injuries and sharp injuries among boys, extroverted personality types, and left-behind pupils whose grandparents were their legal guardians. Animal bites, burns and other injury types were higher among left-behind pupils with an introverted personality, pupils in peer/other guardianship situations, and those with a sub-mental health status. Unharmed left-behind students mainly included those with intermediate personality and mental health characteristics.

Conclusion The injury detection rate among left-behind primary school students is high. Gender, personality type, guardianship type, and mental health status are closely related to injury. Extroverted boys under grandparents guardians are identified as high-risk groups for injury prevention and control. Under the guidance of the precision prevention model, precision intervention strategies for all-round high-risk groups should be carried out in order to effectively reduce the occurrence of injuries among left-behind pupils.

【摘要】 目的 探讨留守小学生伤害影响因素的分布特点, 为划定伤害高危人群和开展伤害精准干预提供参考依据。 方法 于2021年8月至2022年7月, 采用随机整群抽样方法选取平凉市3个乡镇9所小学四至六年级3 769名学生进行问 卷调查。采用多重对应分析方法分析伤害影响因素。 结果 非留守小学生伤害检出率为21.8%(573/2 631);留守小学生 伤害检出率为40.9%(466/1 138), 差异有统计学意义(χ ² = 146.21, P<0.01)。留守小学生伤害中跌落263名, 占比最高 (56.4%);是否独生子女及不同年级、性别、性格、心理状态、监护类型、母亲文化程度伤害检出率差异均有统计学意义(χ ² 值分别为39.05, 96.69, 143.00, 155.80, 461.39, 285.35, 17.10, P值均<0.01)。多重对应分析显示, 跌落、钝器伤和锐器伤在 男生、外向型性格、隔代监护类型的留守小学生中检出率较高;动物咬伤、烧烫伤、其他伤害类型在内向型性格、同代监护和 其他监护类型、心理亚健康特征的留守小学生中检出率较高;未检出伤害者多为中间型性格与心理健康的留守小学生。 结论 留守小学生伤害检出率较高;性别、性格类型、监护类型、心理状态与伤害关系密切, 隔代监护的外向型男生是伤害重 点防控的高危人群。应在精准预防模式指导下开展全方位高危人群精准干预策略, 以期有效降低留守小学生伤害的发生。
