INTRODUCTION: The association between serum vitamin D levels and bone mineral density (BMD) varies by race and gender. This study aimed to evaluate this relationship between serum vitamin D levels and BMD, and changes of BMD over time in Korean women.
MATERIALS AND METHODS: We analyzed data from 586 generally healthy Korean women aged 29-79 who underwent health check-ups at Seoul National University Gangnam Center between 2010 and 2011 (baseline measurement) and 2015-2016 (follow-up). Dual energy X-ray absorptiometry (DEXA) and serum 25-hydroxyvitamin D (25OH-D) level measurements were conducted. We assessed the association between serum 25OH-D levels and BMD, as well as changes in BMD over time.
RESULTS: The mean age of participants was 51.3 ± 7.9 years, with a mean follow-up interval of 4.6 ± 0.7 years, and mean serum 25OH-D level of 20.6 ± 8.5 ng/ml. Baseline serum 25OH-D levels did not correlate with BMD values at the lumbar spine, femoral neck, or total femur, nor with changes in BMD over time. A significant negative association was found between perimenopausal status and BMD changes at all sites, and between premenopausal status and lumbar bone mass, compared to postmenopausal status in the 25OH-D < 20 ng/ml group. This association was not observed in women with higher serum 25OH-D levels.
CONCLUSIONS: Serum 25OH-D levels did not correlate with BMD levels or changes in BMD overall. However, in late reproductive-aged and perimenopausal women with serum 25OH-D insufficiency, there was a significant association with accelerated bone loss.
