In this context the prevalence, patterns and correlates of tobacco use were studied among adolescent school students in Kerala, India.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n Total 7560 students from classes 8, 10 and 12, within the age group of 12-19 yr, across 73 schools in Ernakulam district, Kerala, India, selected by cluster random sampling, completed a self-administered questionnaire incorporating standardized instruments.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Of the 7350 valid questionnaires, the overall lifetime prevalence of tobacco use was 6.9 per cent (12.5% males and 1.2% females). The prevalence of tobacco use increased from 3.1 per cent at 12-13 yr to 15.1 per cent at 18-19 yr. The mean age of onset of tobacco use was 14.0\u00b12.2 yr. The prevalence was higher among students from urban backgrounds, lower socio-economic status and those with part-time jobs. Tobacco users had significantly higher rates of use of alcohol (67.8 vs. 11%) and illicit drugs (33 vs. 6.1%). They had poorer academic performance (24.7 vs. 9.1%), more severe psychological distress (10.8 vs. 4.5%), suicidal attempts (10.2 vs. 3.5%), higher scores of ratings of attention deficit hyperactivity disorder (8.3 vs. 2.5%) and history of sexual abuse (12.5 vs. 3.8%).<\/jats:p>\n <\/jats:sec>\n \n Interpretation & conclusions:<\/jats:title>\n The prevalence of tobacco use in adolescents reported in this study was relatively lower than those reported from other Indian States. However, it correlates with multiple negative outcomes suggesting a need to promote specific interventions to prevent adolescent tobacco use.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/ijmr.ijmr_1873_14","type":"journal-article","created":{"date-parts":[[2017,3,31]],"date-time":"2017-03-31T13:12:30Z","timestamp":1490965950000},"page":"704-711","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":40,"title":["Prevalence & correlates of tobacco use among adolescents in Kerala, India"],"prefix":"10.25259","volume":"144","author":[{"given":"T.
