摘要:Background : Mental disorders of adulthood can be traced to childhood and adolescent disorders so attention to the mental health of young people is important. Objectives : We aimed to determine the mental health status of high-school students in Khorramabad and the factors that may affect it. Methods : This cross-sectional study included 1 202 high-school students in Khorramabad in the 2015–2016 academic year. Students were selected using stratified and multistage cluster random sampling. Data were collected on sociodemographic characteristics of the students, and the General Health Questionnaire (GHQ-28) was used to assess symptoms of mental disorders. Logistic regression analysis was used to evaluate the relationship between the presence of symptoms of mental disorder and sociodemographic characteristics. Results : The mean age of the students was 16.1 (SD 0.9) years and 52.7% were girls. Overall, 481 (40%) students (34% of males, 46% of females) had symptoms of mental disorders. Most had mild symptoms; 5% had severe symptoms. Symptoms of anxiety, depression and social impairment were seen in 40%, 33% and 32% of the students respectively; significantly more girls had these symptoms (P Conclusions : This study found a high prevalence of symptoms associated with mental disorders in the adolescents in Khorramabad. Counselling centres in schools are needed to offer psychiatric counselling services to students and to implement regular mental health training programmes.
