Effectiveness of a School-Based ‘Tobacco Free’ Intervention on Adolescents’ Knowledge and Exposure to Second Hand Tobacco Smoke - A Multiphase Study
There is no safe level of exposure to second hand tobacco smoke (SHS). The World Health Organization has stressed that 100% smoke‐free environments are the only effective way to protect the population from the harmful effects of exposure to SHS. A multiphase study was done among 12 year old adolescents in Mangalore to assess exposure to second hand tobacco smoke at home and to determine their Salivary Cotinine level as well as the knowledge, attitude and avoidance behavior towards second hand tobacco smoke before and after carrying out an educational intervention. A descriptive cross-sectional questionnaire phase 1 on 1442 participants and a phase 2 randomized controlled trial (RCT) with 30 participants each in the experimental and control arms were done. Children’s knowledge, attitude and behavior towards second hand smoke was determined using a 25 item questionnaire, followed by estimation of salivary cotinine levels using the Salimetrics High Sensitivity Salivary Cotinine Quantitative Enzyme Immunoassay Kit, before and after the intervention. The intervention consists of 40 min session delivered once a week for 3 consecutive weeks. The outcome of this research would be useful in developing effective school‐based tobacco intervention policy which could be incorporated into the school curriculum in our country.
