PURPOSE: Tobacco consumption is a problem of public health and it usually initiates during adolescence. It may generate health problems in teenagers and it is one of the causes of early mortality.
METHODS: Objectives: Estimating the prevalence of the tobacco consumption among school adolecents of public and private schools in Salvador (Bahia - Brazil). Methods: Cross-sectional study. Five hundred ninety (590) questionnaires were applied to students at fundamental and high school in five schools at the city of Salvador (2006). The schools had been selected by drawing for a pilot study to evaluate test-retest reliability of the instrument. The life use (experiment), the year use and the month use (current) were considered in order to estimate the prevalence. Statistical analysis: Descriptive and associative measurements (Prevalence Rate-PR), qui-square tests, 95%CI and a significance of 0.05.
RESULTS: Smoking prevalence in life use was 13.9% (78/562) (95% CI = 11.2-17.1). The year use was 9.8% (39/400) (95% CI = 7.1-13.2) and the current use was 5.3% (21/397) (95% CI = 3.4-8.1). According to gender, in life use, 15.2% (38/250) of males and 13.1% (40/206) of females smoked (95% CI = 0.78-1.78; p=0,48). In the year use, 11.3% (24/212) of girls and 8.1% (15/188)of boys smoked (95% CI = 0,4-1.3; p=0.28). To the current use, 3.8% (7/183) of males and 6.6% (14/212) of females (95% CI = 0.2-1.4; p=0.22) smoked tobacco. The relation between the age and life use was significant: 5.4% (12/223) for 12 to 14 years old and 15.9% for 15 to 19 years old, PR=2.95 (15.9/5.4) (95% CI = 1.5-5.7; p=0.001). Tobacco experiment was associated with the fact that either father (PR=1.9; 95% CI = 1.2-3; p=0.001) or mother (PR=1.8; 95% CI = 1.1-3.2; p=0.05) smoked. Neither the year use nor current use were related to the fact that mothers smoked. But the relation with father being a smoker was present.
CONCLUSION: According to this sample, there was no relation between the gender and teenage smoking. Though, it's clearly related to their age. The adolescent was influenced mainly by their fathers.
CLINICAL IMPLICATIONS: Despite the campaigns against tobacco, it was proved that teenagers consume tobacco.This study is important to prevent tobacco use.
