To evaluate postpartum vitamin D deficiency\/insufficiency and to relate it to pregestational BMI, gestational weight gain, and sociodemographic variables.<jats:italic> Methods<\/jats:italic>. This is a cross-sectional study with 225 full-term pregnant women. Data collected are as follows: maternal health, socioeconomic status, pregestational body mass index (BMI), and gestational weight gain. Laboratory evaluation included vitamin D [25(OH)D], calcium, phosphorus, magnesium, and alkaline phosphatase.<jats:italic> Results<\/jats:italic>. The mean age of women was 25.6\u00b16.6 years. Dark skin color, low education, and work in the urban region were predominant. Regular sun exposure, photoprotection, and vitamin D supplementation were reported by 144 (64.0%), 44 (19.6%), and 5 (2.2%) women, respectively. The mean plasma concentrations of 25(OH)D were 26.0\u00b16.8\u2009ng\/mL. Levels compatible with deficiency (&lt;20\u2009ng\/mL) and insufficiency (20-30\u2009ng\/mL) were observed in 43 (19.1%) and 124 (55.1%) women, respectively. The increase of 1\u2009ng\/mL in 25(OH)D concentrations was associated with an increase of 0.16\u2009mg\/dL (95%CI 0.19 to 2.02; p=0.018) for calcium. There were no associations with 25(OH)D concentrations with pregestational BMI and with gestational weight gain.<jats:italic> Conclusions<\/jats:italic>. The high frequency of postpartum vitamin D deficiency\/insufficiency in women with a full-term pregnancy in a region with a large and permanent sun exposure reminds us of the need for intervention policies aimed at preventing vitamin D deficiency during pregnancy.<\/jats:p>","DOI":"10.1155\/2018\/1070528","type":"journal-article","created":{"date-parts":[[2018,9,2]],"date-time":"2018-09-02T19:30:59Z","timestamp":1535916659000},"page":"1-6","source":"Crossref","is-referenced-by-count":4,"title":["Vitamin
