Objective: To explore the correlation of health literacy and mobile phone use dependence with psychopathological symptoms in middle school students. Methods: 22 628 middle school students in Shenyang, Bengbu, Xinxiang, Ulanqab, Chongqing and Yangjiang were enrolled by multistage cluster sampling method from November 2015 to January 2016. Chinese Adolescent Interactive Health Literacy Questionnaire (CAIHLQ), Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use (SQAPMPU) and Multidimensional Sub-health Questionnaire of Adolescents (MSQA) were applied to acquire basic characteristics, health literacy, mobile phone use dependence and psychopathological symptoms of subjects. Subjects were classified into three groups, low level (<P(25)), medium level (P(25)-P(75)) and high level (>P(75)), according to the percentile of the questionnaire score. Multivariate logistic regression model was used to analyze the correlation of health literacy, mobile phone with psychopathological symptoms. Results: The students were (15.4±1.8) years old with 10 990 boys (48.6%). The score of health literacy of students were (104.1±18.7) points. The rate of mobile phone use dependence was 25.4% (5 752/22 628) and the rate of psychopathological symptoms was 29.1% (6 581/22 628). Compared with high health literacy level, medium and low health literacy levels were related to psychopathological symptoms, with OR (95%CI) about 2.30 (2.10-2.52) and 5.40 (4.89-5.97), respectively. Compared with mobile phone use independence, mobile phone use dependence was related to psychopathological symptoms, with OR (95%CI) about 3.60(3.37-3.85). The highest rate of psychopathological symptoms occurred in students with mobile phone use dependence and low health literacy level [68.0% (1 345/1 977)], with OR (95%CI) about 19.59 (17.07-22.48). Conclusion: Health literacy and mobile phone use dependence are related factors of psychopathological symptoms in middle school students.
目的： 探讨中学生健康素养和手机使用依赖与发生心理病理症状的关联。 方法： 2015年11月至2016年1月采用多阶段整群抽样方法，在沈阳、蚌埠、新乡、乌兰察布、重庆和阳江等6个城市抽取中学生22 628名，分别采用《中国青少年互动性健康素养问卷》、《青少年手机使用依赖自评问卷》和《青少年亚健康多维评定问卷》获取调查对象的基本特征、健康素养状况、手机使用状况和心理病理症状。根据问卷得分百分位数将研究对象分为低水平（<P(25)）、中等水平（P(25)~P(75)）和高水平（>P(75)）3组，采用多因素logistic回归模型分析手机使用依赖和健康素养与发生心理病理症状的关联。 结果： 调查对象的年龄为（15.4±1.8）岁，其中男生10 990名（48.6%）。调查对象健康素养得分为（104.1±18.7）分，手机使用依赖和心理病理症状检出率分别为25.4%（5 752/22 628）和29.1%（6 581/22 628）。与高健康素养水平相比，中等和低健康素养水平与心理病理症状有关联，OR（95%CI）值分别为2.30（2.10~2.52）和5.40（4.89~5.97）。与无手机使用依赖相比，手机使用依赖与发生心理病理症状有关联，OR（95%CI）为3.60（3.37~3.85）。有手机使用依赖且低健康素养水平的中学生心理病理症状检出率最高，为68.0%（1 345/1 977），OR（95%CI）值为19.59（17.07~22.48）。 结论： 中学生健康素养和手机使用依赖与发生心理病理症状有关联。.
