Abstract:

Background: The main constituent of Bone Mineral Density (BMD) is bone mineral, with the main composition of the hydroxyapatite complex, a combination of calcium and phosphorus. In the aging process, the mineral content in the bones will decrease, resulting in lower BMD than normal levels (osteopenia) or leading to the most common musculoskeletal disorder as well as morbidity in the elderly population. This study aims to determine the correlation between BMD and blood phosphorus levels in elderly women. Methods: This cross-sectional study was based on data from several geriatric health centers in Semarang from March until June 2019. There were 29 female respondents aged ? 60 years who participated and signed informed consent of this study. The study performed laboratory tests to assess blood phosphorus levels and BMD examination with Dual Energy X-ray Absorption (DXA). BMD is categorized based on World Health Organization (WHO) criteria into normal, osteopenia, and osteoporosis categories. Data were analyzed using SPSS version 17 for Windows. Results: Most of the subjects were 60-69 years old group (69.0%), followed by osteoporosis in the BMD category (62.0%) and normal blood phosphorus levels (83.0%). There was no significant correlation between BMD and blood phosphorus levels (p> 0.05), but there was a tendency for a negative correlation between BMD and blood phosphorus levels (r=-0.096). Conclusion: The result shows no correlation between blood phosphorus level and BMD.
