Abstract:

Objective To study the relationship between vitamin D deficiency, defined as 25-hydroxyvitamin D3 (25 (OH) D3) deficiency and the risk of orthostatic hypotension (OH) in the elderly population. Methods From the establishment of the database to June 2023, a systematic literature search was conducted on Pubmed, Embase, Web of Science, Scopus, and Cochrane databases. Two researchers independently screened the included literatures, extracted data and evaluated the risk of bias of the included studies. Meta-analysis was performed using Stata software (version 17.0) and RevMan5.4 software. Results A meta-analysis was conducted using the random-effect model involving 9,155 participants from 9 cross-sectional studies. Serum 25-hydroxyvitamin D levels were measured by radioimmunoassay (RIA) and liquid chromatography mass spectrometry (LC-MS). The overall analysis results showed that vitamin D deficiency was directly correlated with OH in the elderly population. Compared with individuals with normal vitamin D levels, low serum vitamin D levels significantly increased the risk of OH in the elderly (OR=1.22, 95%CI=1.12-1.33,P<0.05). Conclusion There is a clear correlation between vitamin D deficiency and the risk of OH in the elderly.

Key words: hypotension, orthostatic, elderly, 25-hydroxyvitamin D, meta-analysis
