WEDNESDAY, Aug. 11, 2021 (HealthDay News) — U.S. Black women with lower serum levels of vitamin D (25[OH]D) may be at increased risk for COVID-19 infection, according to a study published online July 27 in PLOS ONE<\/em>.<\/p>\n Yvette C. Cozier, D.Sc., M.P.H., from the Slone Epidemiology Center at Boston University, and colleagues analyzed serum 25(OH)D levels in relation to COVID-19 infection among participants in the Black Women’s Health Study. The analysis included 1,974 women with 25(OH)D blood test results and a COVID-19 test in 2020.<\/p>\n After adjusting for age, number of people living in the household, neighborhood socioeconomic status, and other potential confounders, the researchers found that compared with women with 25(OH)D levels \u00e2\u0089\u00a530 ng\/mL, the odds ratios for COVID-19 infection in women with levels of 20 to 29 ng\/mL and <20 ng\/mL were 1.48 (95 percent confidence interval, 0.95 to 2.30) and 1.69 (95 percent confidence interval, 1.04 to 2.72), respectively (P trend = 0.02).<\/p>\n “Nearly one out of four people have vitamin D blood levels that are too low or inadequate for bone and overall health,” Cozier said in a statement. “Our study provides another reason why adequate levels of vitamin D are important — the possibility of lowering risk of COVID-19 infection.”<\/p>\n
