BACKGROUND: @entity286 consumption is a net increase in our areas. In Senegal, as in other African countries, sponsorship of cultural and sporting events in schools promote @entity286 use among schoolchildren. Our objective was to assess the prevalence of @entity286 in the French School of Jean Mermoz of Dakar by a survey completed by a measurement of @entity1223 (CO) in expired air. METHODS: seven hundred forty-one students (n = 402 @entity1 and n = 339 @entity1 ), aged 11 to 18 years of French and African cultures, participated in the study. A questionnaire with several items of smoking has been distributed to them . Two weeks after the collection of questionnaires, the CO measuring for all students was conducted. RESULTS: The prevalence of smoking in High School was 23.1% and smoking was found more in @entity1 according to the questionnaire and piCO+TM with 13.7% and 7.1% respectively. It affected over the upper age class or equal to fifteen years. The most mentioned reason for the initiation of smoking (45.4% of smokers) was curiosity with a need to be free, followed by the influence of the environment famial (44.4%) and friendly (20.5%). The measurement of @entity1223 showed that 12.4% of our subjects had a smoking profile with 8% light smoking, 1% moderate smoking, and severe smoking was 3% of our students. A significant difference (p = 0.0021) between the two prevalences was found. CONCLUSION: The @entity1223 intoxication by @entity286 use is responsible for microcirculatory accidents such as tissue @entity519 , whereas smoking affects young students, in which the phenomenon is more precocious. Thus it is urgent to establish a policy of @entity286 control in schools.
