Objective The present study aimed to determine the prevalence of unintentional injuries and examined psychopathological sub-healthy status and problematic mobile phone use with unintentional injuries in middle schools students,and to provide reference for its controlling and to prevention.Methods A total of 22 628 junior and high school students selected from Shenyang,Bengbu,Xinxiang,Ulanqua,Chongqing and Yangjiang in China were enrolled in this study from November 2015 to January 2016.Psychopathological sub-healthy status,PMPU,and unintentional injuries were measured with multidimensional sub-health questionnaire of adolescents (MSQA),self-rating questionnaire for adolescent problematic mobile phone use(SQAPMPU),and the questionnaire of unintentional injurious.Results The prevalence of unintentional injuries was 46.7%,the prevalence of scratch,falls,and cut were 29.4%,19.7%,16.3%,respectively.The prevalence of total unintentional injurious,scratch,falls,and cut among psychopathological sub-healthy status and control group were 55.1% vs 43.3%,34.8% vs 27.1%,26.0% vs 17.2%,23.0% vs 13.6%,respectively,and the difference was statistically significant(x2 =261.62,134.12,228.63,302.79,P<0.01).The prevalence of total unintentional injurious,scratch,falls,and cut among problematic mobile phone use and control group were 53.6% vs 44.4%,33.2% vs 28.0%,25.5% vs 17.8%,21.6% vs 14.5%,the difference was statistically significant(x2 =145.09,55.21,163.92,160.24,P<0.01).According to univariate logistic regression analysis,psychopathological sub-healthy status and problematic mobile phone use were independent risk factor for unintentional injurious.The interaction between them significantly increased the risk of unintentional injurious.Conclusion Adolescent psychopathological sub-healthy status and problematic mobile phone use are important factors in unintentional injurious,and concerning about the psychopathological sub-healthy status and problematic mobile phone use are beneficial to the prevention and control work of unintentional injurious.
