| Résumé : | [BDSP. Notice produite par INIST-CNRS Fm9R0xC8. Diffusion soumise à autorisation]. Physical functioning measures are considered integrated markers of the aging process. This prospective investigation examined relations between dietary intake of women at midlife in 1996-1997 and prevalence of physical functioning limitations 4 years later, defined by the Medical Outcomes Study Short-Form 36. The sample included 2,160 multiethnic women, aged 42-52 years, from six geographic areas participating in the Study of Women's Health Across the Nation (SWAN). Associations between measures of diet quality and number of fruit and vegetable servings and prevalent physical functional limitations (no, moderate, or substantial limitations) were tested by logistic regression. The prevalence of moderate and substantial functional limitations was 31% and 10%, respectively. Women in the highest quartile of cholesterol intake had 40% greater odds (odds ratio=1.4,95% confidence interval : 1.1,1.8) of being more limited versus those in the lowest quartile. Women in the highest quartile of fat and saturated fat intakes were 50% and 60% more likely to be more limited, with respective odds ratios of 1.5 and 1.6 (95% confidence intervals : 1.2,2.0 and 1.2,2.1) versus those in the lowest quartiles. Lower fruit, vegetable, and fiber intakes were related to reporting greater functional limitations. Modifying dietary practices could be important in minimizing physical limitations. |
