Association between Vitamin D and Calcium Level and BMD Alteration in Post-Menopausal Osteoporosis Patients Treated with Bisphosphonate Therapy for at Least 1 Year in Saiful Anwar Hospital Malang

Post-menopausal osteoporosis is a degenerative disease among post-menopausal women. In Indonesia, women over 50 years old get post-menopausal osteoporosis.The therapy should be comprehensive and continous. Bisphosphonate therapy is one of the most preferable therapeutic option for maintaining bone density. Calcium and vitamin D have a role in increasing osteoblastic activity. The objective of this study was to describe the vitamin D and calcium in bone mineral density (BMD) of hip and spine in postmenopausal woman with biphosphonat therapy. This study is a cross-sectional, observational analytic. The subject were female patients with post-menopausal osteoporosis treated in clinic of RSUD dr. Saiful Anwar Malang, who had received routine bisphosphonate for at least 1 year. The method was collecting the patient data, who received oral and injectie bisphosphonate therapy, serial BMD test,hip and spine, vitamin D and calcium level in serum test. Total sample 25 participan, the association between BMD change (Δ BMD), vitamin D and calcium level, were analyzed.with Chi Square test then continued using Spearman correlation test. Vitamin D levels in Δ BMD Spine in participants was less <30 ng/ml, mean 16.8+6.95 14 respondents (56%), and 6 respondens (24%) 10.05+5.28, normal vitamin D levels were 5 respondents (20%) mean 34.16+5.10. Vitamin D levels in Δ BMD Hip in participants was less
