Effect of PM2.5 exposure on Vitamin D status among pregnant women: A distributed lag analysis

Abstract

Our study provided suggestive evidence that PM_2.5 exposure at 1-10 weeks before the 25(OH)D detection may decrease the circulating 25(OH)D levels in pregnant women and increase VDD risk in pregnant women. More attention should be paid to the long-term impact of PM_2.5, in particular, during weather conditions with a relatively short duration of sunshine.
