Objective: Menopause is a sensitive and challenging period for women, which leads to various problems such as osteoporosis and back pain. However, its effect on bone mineral density is still debatable. Therefore, the aim of this study was to determine The relationship between some serum osteoporosis markers and body mass index with lumbar bone mineral density in active and inactive postmenopausal women. Methods: The number of subjects was 41 active postmenopausal women and 45 inactive postmenopausal women aged 46 to 87 years. Serum alkaline phosphatase, calcium and phosphorus indices and anthropometric characteristics of the subjects were examined. Pearson correlation coefficient test was used to analyze the research data. SPSS version 26 software was used to analyze the data. Results: We observed a statistically significant correlation between serum levels of alkaline phosphatase, calcium, and phosphate with lumbar bone mineral density in the group of active postmenopausal women, and between body mass index, weight, and age with lumbar bone mineral density in both active and inactive postmenopausal women (p ≥ 0.05). While no significant correlation was found between other indices. Conclusion: Active postmenopausal women, by taking advantage of sports activity, in addition to having better health indicators, have provided the necessary stimulus for some hormonal mechanisms, mineral absorption, and calcium-phosphorus balance in order to reduce bone resorption.
