AB The age of initiation influence smoking habit in adult.Methods: On the annual PST survey from 2002 to 2015 on a randomized select sample of 2% of 12-19yo Parisian schoolchildren, We analysed the population according to age of initiation: until 14, 15-17yo, more than 17yo.Results: Among a total of 11 511 schoolchildren respondent from 18-19yo included in the 13 cross sectional surveys, 4 113 (35.7%) report an age of first experimentation of tobacco and are the study group. 47.7% are males, 52.3% females.Non-smokers respond on experimentation in 1.1% of case, ex-smokers in 43.4%, occasional smokers in 76.1 and daily smokers in 98.4% of case. An experience of tobacco before 15yo is associated with a 70.5% rate of daily smokers and 20.6% rate of occasional smokers at 18-19yo; when experienced came after 17yo a 56.5% daily smokers rate and 39.1% occasional smokers was reported at 18-19yo.The ratio of only daily smoker/smoker increase with the decrease of age of first experimentation. For an initiation before 15 years old, 77.4% for an initiation before 15yo, 74.1% for an initiation between 15 and 17 yo, and 66.0% for an initiation after 17yo. The tobacco dependence asses by HIS is higher in early experimenters.Conclusions: An initiation of tobacco before 15 years is associate with a high rate of daily smokers and high tobacco dependence at 18-19 yo. All measure who postpone the age of tobacco experimentation are welcome.
