Low serum vitamin D levels increase the mortality of cardiovascular disease in older adults: A dose-response meta-analysis of prospective studies

Medicine (Baltimore). 2019 Aug;98(34):e16733. doi: 10.1097/MD.0000000000016733.

Abstract

Lower circulating vitamin D is common in older adults and may be a potential reversible risk factor for cardiovascular disease (CVD) in older adults, however, presented controversial results.Database was searched update to February 2018. Key data were extracted from eligible studies. Dose-response meta-analysis were conducted for synthesizing data from eligible studies.A total of 13 eligible studies involving 21,079 participants were included in this meta-analysis. Person with lower 25-hydroxyvitamin D status (25 (OH)D level <50 nmol/L) appeared to have higher mortality of CVD in older adults (RR = 1.54, 95% CI 1.24-1.91). Furthermore, a significantly higher mortality of CVD in older adults was observed for the deficient (<25 nmol/L; RR = 1.47, 95% CI 1.15-1.81) and insufficient (25-50 nmol/L; RR = 1.16, 95% CI 1.04-1.27) categories of 25 (OH)D, compared to the reference category of >75 nmol/L. Additionally, decrease of 10 nmol/L 25-hydroxyvitamin D was associated with a 7% incremental in the risk of CVD mortality in older adults.Considering these promising results, circulating vitamin D is associated with CVD mortality increment in older adults.
