Vitamin D insufficiency during pregnancy has been associated with a number of adverse outcomes for both mother and child. Vitamin D insufficiency has been well described in many populations of both pregnant and non‐pregnant women of childbearing age, but there is a lack of data on women living in South‐East Asia. We measured plasma 25‐hydroxyvitamin D in a representative sample of pregnant ( n = 64) and non‐pregnant ( n = 477) women (15–49 years) living in Hanoi City ( n = 270) and rural Hai Duong Province ( n = 271) in northern Vietnam. Mean 25‐hydroxyvitamin D (95% confidence interval) concentration was 81 (79, 84) nmol L −1 . Mean 25‐hydroxyvitamin D concentration differed between urban and rural (78 vs. 85 nmol L −1 ; P = 0.016), farming and non‐farming (89 vs. 77 nmol L −1 ; P < 0.001) but not pregnant and non‐pregnant or older vs. younger women. Only one woman had a 25‐hydroxyvitamin D less than 25 nmol L −1 , a concentration indicative of vitamin D deficiency. Of the women, 7% and 48% of the women were vitamin D insufficient based on cut‐offs for plasma 25‐hydroxyvitamin D of 50 and 75 nmol L −1 , respectively. Mean plasma 25‐hydroxyvitamin D concentrations of these Vietnamese women were much higher than those reported in other studies of pregnant and non‐pregnant women in the region.
