Background: With the rapid growth of the elderly population, osteoporosis has become a major health problem worldwide. Although health knowledge and self-efficacy are important assets to facilitate healthy behaviors and disease prevention, such information as it relates to individuals and their bone health is limited. The purpose of this study was to assess the levels of knowledge, self- efficacy, and health behaviors on promoting bone health in middle-aged Korean women.
Methods: This is a cross-sectional survey study. A convenience sampling of middle-aged women (≥40 years) was done at a community health center in Korea. Bone mineral density was measured by dual energy X-ray absorptiometry with the DEXXUM T. The level of knowledge was measured with the Knowledge of Osteoporosis Scale, and self-efficacy with the Osteoporosis Self-efficacy Scale. A questionnaire for bone health behaviors was developed for this study. Collected data were analyzed through descriptive methods, independent t-test, analysis of variance, and Pearson’s correlation analysis.
Results: A total of 150 middle-aged women whose mean age was 59.8±11.5 years participated in the study. Most (74%) were menopausal. Less than one-quarter of participants (22.7%) had osteoporosis and less than half (42%) had osteopenia based on the T-score at the left femur neck site. Level of knowledge (mean score, 10.35) and self-efficacy (mean score, 47.67) ranged from low to moderate. Intake of calcium and vitamin D-rich foods was insufficient in our subjects. Bone health behaviors had significant positive relationships with knowledge (r=0.22, P=0.008) and self-efficacy (r=0.29, P<0.001) on promoting bone health.
Conclusions: These results indicate that educational interventions are needed to enhance knowledge and confidence and to encourage middle-aged women to engage in bone health behaviors.
