Health and dietary characteristics of supplement users in an elderly population.
The purpose of this study was to investigate the association of health and dietary characteristics with the use of vitamin and mineral supplements in community-dwelling, cognitively intact elders aged in their 60s (n = 89), 80s (n = 92), and 100s (n = 76) who resided in Georgia in the southeastern United States. Elders who were physically active (p = 0.008), had stomach problems (p = 0.042), or used arthritis medication (p = 0.015) were more likely to take a nutritional supplement than elders without these characteristics. Physically active elders were more likely to take calcium (p = 0.004), vitamin E (p = 0.022), and vitamin C (p = 0.046) than non-physically active elders. Compared to non-users, supplement users were also more likely to comply with nutritional health seeking behaviors such as avoiding too much salt, fat, cholesterol, sugar, caffeine, and eating enough fiber, vitamins and minerals from food or supplements, and calcium in foods or supplements. The observation that the use of certain vitamin or mineral supplements is associated with dietary fat intakes, dietary protein intakes, and patterns of alcohol, decaffeinated coffee, and tea consumption suggests that supplement use is one of a cluster of health behaviors. Thus, it may be important that future investigations concerning the impact of supplement use on diseases, such as heart disease or cancer, control for the effects of dietary patterns and physical activity.
