This cross-sectional study was conducted with the aim of examining the relationships between smoking behavior and leisure physical activity habits of adolescents (n=170, 85F & 85M, mean age= 15.42 [plus or minus] 0.58, age range=15-17 years) attending vocational health schools in Turkey. Participants were randomly selected from four provinces of the country and classified into two groups according to their participation in leisure physical activity. The logistic regression analysis of the data suggested there was a significant relationship between gender (being female) (OR=0.28), non-smoking (OR=0.39) and participating in leisure physical activities. Furthermore, being a female, age 16 years and over, and fathers' low education levels were also found to have a higher risk of smoking habits (OR=0.30, p=0.018; OR=0.33, p=0.023; OR= 3.92, p=0.004 respectively).
