[BDSP. Notice produite par INIST 1DZ45R0x. Diffusion soumise à autorisation]. Objectives. This analysis tested the relation between dieting frequency and risk of smoking initiation in a longitudinal sample of adolescents. Methods. From 1995 to 1997,1295 middle school girls and boys participated in a nutrition and physical activity intervention study. The prospective association between dieting frequency at baseline and smoking initiation 2 years later was tested. Results. Compared with girls who reported no dieting at baseline, girls who dieted up to once per week had 2 times the adjusted odds of becoming smokers (odds ratio=2.0 ; 95% confidence interval=1.1,3.5), and girls who dieted more often had 4 times the adjusted odds of becoming smokers (odds ratio=3.9 ; 95% confidence interval=1.5,10.4). Conclusions. Dieting among girls may exacerbate risk of initiating smoking, with increasing risk with greater dieting frequency.
