Association of standardized serum 25-hydroxyvitamin D with falls in post-menopausal women.
Vitamin D status has long been related to falls risk. In this planned secondary analysis of a vitamin supplementation trial in postmenopausal women, standardized 25-hydroxyvitamin D concentration up to 60 ng/mL was not associated with increased falls. Women with 25(OH)D ≥ 60 ng/mL had higher odds of ≥ 2 falls.
Purpose: Falls are common and cause fractures. High circulating 25(OH)D may increase falls risk; thus, recent guidance recommends 25(OH)D not exceed 50 ng/mL. Prior falls studies have not reported standardized 25(OH)D (s25D) data. The purpose of this planned secondary analysis of a 4-year calcium/vitamin D supplementation trial was to evaluate the association of s25D with falls.
Methods: This study recruited 2,303 postmenopausal women. The analytic dataset consisted of pooled concatenated data from years 2-4 (NTotal = 5,732). Serum 25(OH)D was measured annually and subsequently retrospectively standardized using Vitamin D Standardization Program methods. Falls were recorded by diary. Incidence for ≥ 1 fall and ≥ 2 falls was assessed by s25D group (≤ 20, 20- < 30, 30- < 40, 40- < 50, 50- < 60 and ≥ 60 ng/mL) using multivariable logistic regression.
Results: Mean (SD) baseline s25D was 32.6 ng/mL (8.3) with no difference between supplement and placebo groups. s25D increased to 41.3 ng/mL at year 2 in the supplement group then remained stable. By s25D group, incidence for ≥ 1 fall varied from 22-32% (p = 0.19). For ≥ 2 falls incidence varied (p = 0.03) from 6% (< 20 ng/mL) to 17% (≥ 60 ng/mL.) There was no significant association between s25D and ≥ 1 fall. Those with s25D ≥ 60 ng/mL had a higher adjusted odds of ≥ 2 falls (OR = 1.99 ± 1.2-3.3) compared to women with s25D of 30- < 40 ng/mL.
Conclusion: s25D up to 60 ng/mL was not associated with greater risk for ≥ 1 or ≥ 2 falls. Women with a s25D ≥ 60 ng/mL were at higher odds for ≥ 2 falls, however this group included only ~ 2% of study observations; therefore, confirmation in other cohorts is necessary.
期刊介绍：
An international multi-disciplinary journal which is a joint initiative between the International Osteoporosis Foundation and the National Osteoporosis Foundation of the USA, Osteoporosis International provides a forum for the communication and exchange of current ideas concerning the diagnosis, prevention, treatment and management of osteoporosis and other metabolic bone diseases.
It publishes: original papers - reporting progress and results in all areas of osteoporosis and its related fields; review articles - reflecting the present state of knowledge in special areas of summarizing limited themes in which discussion has led to clearly defined conclusions; educational articles - giving information on the progress of a topic of particular interest; case reports - of uncommon or interesting presentations of the condition.
While focusing on clinical research, the Journal will also accept submissions on more basic aspects of research, where they are considered by the editors to be relevant to the human disease spectrum.
