- Abstract
Introduction The first and only nationally representative prevalence estimates of psychiatric disorders in Mexico (the Mexican National Comorbidity Survey) indicate sex differences in the expression of psychopathology and early ages of onset for most disorders, often in the adolescent years. Studies from other countries have shown that sex differences in the pattern of psychopathology vary by life stage, which in part, may be explained by different ages of onset for varying disorders. These studies also suggest that many of the sex differences in the prevalence of disorders emerge during the adolescent years. However, scarce data is available on the epidemiology of adolescent psychopathology in Mexico, and much less regarding possible sex differences in the patterns of prevalence, severity and ages of onset. The purpose of this report, therefore, is to estimate sex differences in the 12-month prevalence and severity of 17 psychiatric disorders (using DSM-IV diagnostic criteria) as well as ages of onset in adolescents from Mexico City metropolitan area. Materials and methods This article provides data from the Mexican Adolescent Mental Health Survey. This survey has a multistage probability design and is representative of adolescents between 12 and 17 years old who reside in the Mexico City metropolitan area. The final sample included 3005 adolescents selected from a stratified multistage area probability sample. In all strata, the primary sampling units were census count areas cartographically defined and updated in 2000 by the Mexican National Institute of Statistics, Geography and Informatics (INEGI). Two hundred census count areas were selected with probability proportional to size. Secondary sampling units were city blocks, four of which were selected with probability proportional to size from each census count area. All households within these selected city blocks with adolescents aged 12 to 17 were selected. One eligible member from each of these households was randomly selected using the Kish method of random number charts. The response rate of eligible respondents was 71%. The adolescents were interviewed in their homes by trained lay interviewers using the computerized adolescent version of the World Mental Health Composite International Diagnostic Interview (WHM-CIDI-A 3.0). The average length of the interview was two and a half hours. A verbal and written explanation of the study was given to both parents and adolescents. Interviews were administered only to those for whom signed informed consent from a parent and/or legal guardian were obtained as well as the adolescent agreement. Because of the stratified multistage sampling design, data was subsequently weighted to adjust for differential probabilities of selection and non-response. Post-stratification to the total Mexico City Metropolitan Area adolescent population according to the year 2000 Census in target age and sex ranges were also performed..…
