Abstract

The purpose of this study was to determine the extent and integration of osteoporosis knowledge in three age groups of women and compare knowledge to calcium intake and weight-bearing physical activity (WBPA). In this cross-sectional study, knowledge, calcium intake and WBPA were assessed using probe interviews, a food frequency and an activity questionnaire, respectively. Seventy-five white women were separated into three groups: young (25–35 years), middle aged (36–46 years) and postmenopausal (50+ years). Concept maps were used to assess knowledge (concepts, integration and misconceptions). Calcium intakes from diet, supplements and fortified orange juice were estimated as were minutes of daily WBPA. Analysis of covariance was used to compare knowledge, calcium intake and WBPA by age group. Covariates included education, family history, physical problems making exercise difficult, and lactose intolerance. Chi square analysis was used to determine differences in these covariates across age groups. Correlations and regression analysis were used to determine relationships between knowledge and behaviors. Knowledge scores averaged 32–44 points (183 possible). Average calcium intake in all groups exceeded the Dietary Reference Intake's recommended Adequate Intake but 20–24% consumed less than 60% of the AI. Housework, walking at work, and standing at home and work accounted for 90% of WBPA. Knowledge about osteoporosis was limited and not associated with age, WBPA or calcium intake. Calcium intake and WBPA were not associated with age. Practitioners need to provide explicit information on osteoporosis and risk reducing behaviors to women of all ages.
