Abstract The aims of this study were to explore the vitamin D status among a sample of Jordanian postpartum women and identify factors associated with vitamin D deficiency. A total of 171 postpartum women agreed to participate. Participants completed a questionnaire on factors related to vitamin D deficiency and provided a blood sample to assess their plasma vitamin D (25(OH)D) levels using DIA source Immuno-Assays S.A. analysis. The majority of women (76%, n = 130) had vitamin D deficiency and 24% (n = 41) of participants had vitamin D insufficiency. Factors associated with vitamin D deficiency were younger age (< 30 years), low education level, unemployment, multiparity, lactation, dress style, limited sunlight exposure, high BMI, dark skin colour and lack of multivitamin use. Vitamin D supplementation must be considered during pregnancy and lactation to prevent hypovitaminosis in both mother and baby.
