Exposure to secondhand smoke In 2003, exposure to SHS at home was significantly higher in Lima and Tarapoto (25.1% and 27.2%, respectively) than in Huancayo and Trujillo (17.8% and 19.8%, respectively) (Table 4). However, exposure to SHS at home declined between 2000 and 2003 in Huancayo (from 23.7% to 17.8%) and Trujillo (from 27.8% to 19.8%). In 2003, exposure to SHS in public places was signifi- cantly higher in Lima (41.7%) than in Huancayo (30.2%). There was no significant change over time in exposure to SHS in public places in any of the four sites between 2000 and 2003. Almost 9 in 10 students in each of the four sites thought smoking should be banned in public places. There was no significant change in support of smoke free environments in any of the sites between 2000 and 2003. Taught in school about tobacco Students were asked if, during the past school year in classes, they had been taught about the dangers of tobacco, discussed the reasons why young people smoke, or if they had been taught about the effects of tobacco on their health. Students in Tarapoto were more likely than students in the other sites to have been taught about the dangers of tobacco, to discuss the reasons why people their age smoke, or to have been taught about the effects of tobacco on their health (64.9%, 55.3%, and 50.4%, respectively; Table 5). There was no significant change over time for any of the four sites between 2000 and 2003 in any of these measures. Media and advertising exposure Over 7 in 10 students in each of the four sites reported that they saw tobacco advertisements on billboards Page 5 of 9 (page number not for citation puroposes)
