Abstract

The vitamin D debate relates in part to ideal public health population levels of circulating 25-hydroxyvitamin D (25OHD) to maintain bone structure and reduce fracture. In a secondary analysis of 1,348 women aged 70-85 years at baseline (1998) from the Perth Longitudinal Study of Aging in Women (PLSAW, a five-year calcium supplementation trial followed by two five-year extensions), we examined the dose-response relations of baseline plasma 25OHD with hip DXA BMD at year 1, lumbar spine BMD and trabecular bone score (TBS) at year 5, and fracture-related hospitalizations over 14.5 years obtained by health record linkage. Mean baseline plasma 25OHD was 66.9±28.2 nmol/L and 28.5%, 36.4% and 35.1% of women had levels50 nmol/L are a minimum public health target and 25OHD levels beyond 75 nmol/L may not have additional benefit to reduce fracture risk.
