Résumé : | [BDSP. Notice produite par INIST-CNRS ToR0xBIT. Diffusion soumise à autorisation]. The role of antioxidant intake in osteoporotic hip fracture risk is uncertain and may be modified by smoking. In the Utah Study of Nutrition and Bone Health, a statewide, population-based case-control study, the authors investigated whether antioxidant intake was associated with risk of osteoporotic hip fracture and whether this association was modified by smoking status. The analyses included data on 1,215 male and female cases aged>50 years who incurred a hip fracture during 1997-2001 and 1,349 age-and sex-matched controls. Diet was assessed by food frequency questionnaire. Among ever smokers, participants in the highest quintile of vitamin E intake (vs. the lowest) had a lower risk of hip fracture after adjustment for confounders (odds ratio=0.29,95% confidence interval (Cl) : 0.16,0.52 ; p-trend |
