Meta Analysis
Vitamin D insufficiency and cognitive impairment in Asians: a multi-ethnic population-based study and meta-analysis.
The relationship between vitamin D insufficiency and cognitive impairment remains equivocal in Asians. We examined the association between circulating 25-hydroxyvitamin D (25OHD) concentration and cognitive performance in a large multi-ethnic Singaporean population-based study. We also conducted a meta-analysis of 25OHD concentrations amongst cognitively impaired older adults in Asia. ⋯ Vitamin D insufficiency is associated with a greater likelihood of and more severe cognitive impairment in Asian populations.
