摘要

Background: Taking calcium supplements is a common health behavior among the elderly for prevention of osteoporosis and fractures. Furthermore, several studies have indicated that sufficient calcium intake might decrease the incidence of colon cancer. The purpose of this study was to explore the association between habitual intake of calcium supplements and background variables of the elderly in Taiwan.
Methods: A population-based sample obtained from the Bureau of Health Promotion was followed from 1999 to 2003. A total of 1393 subjects (age＞70) participated in this study during the 4-year follow-up. General background information was acquired via questionnaires from each participant based on current health behaviors, preexisting systemic diseases, having a habit of taking alternative medicine and nutritional supplements. The data were analyzed by logistic regression.
Results: The prevalence rates of taking calcium supplements in 1999 and 2003 were 14.7% and 16.1%, respectively. Our results showed that female (OR: 3.26 [2.20-4.80], p＜0.001), higher education level (OR=2.17 [1.38-3.41], p=0.001), regular exercise (OR=1.51 [1.03-2.21], p=0.034), and taking multivitamins and minerals (OR=1.90 [1.22-2.98], p=0.005) were predictive factors for initiating calcium intake among the elderly in Taiwan. In the subgroup of female, only financial status showed a significant difference, whereas in the subgroup of male, education level and having diabetes mellitus were statistically significant.
Conclusions: Based on the results of the 4-year follow-up of 1393 subjects from 1999 to 2003, factors associated with changes in habitual intake of calcium supplements among the elderly in Taiwan emerged to be female, higher education level, regular exercise and taking multivitamins and minerals. Surprisingly, subjects at high risk of developing osteoporosis and fractures did not start taking any calcium supplements for purpose of prevention. Therefore, our medical team should focus more on conveying the benefits of taking calcium supplements to the general public, particularly those elderly persons at high risk..
