The study involved 127 pregnant women, 40 pregnant smokers and 87 pregnant nonsmokers, admitted to a maternity hospital in S\u00e3o Paulo, Brazil. Data concerning the pregnant women's socioeconomic, demographic, obstetric, and nutritional characteristics were collected, as well as data concerning the newborns' anthropometry and Apgar scores. A strongly significant correlation (p &lt; 0.001) was found between the concentrations of ascorbic acid (AA) in both pregnant smokers (r = 0.77) and pregnant nonsmokers (r = 0.61) and their respective umbilical cords. The mean umbilical AA concentration was significantly higher than the mean AA concentration in pregnant women (92.05 \u00b1 41.13 vs. 33.39 \u00b1 18.25 mumol\/L, p &lt; 0.001). It was observed that the mean AA was significantly lower for the newborns (p = 0.03) and pregnant women (p = 0.02) from the smoking group. Forty percent (40%) of the smokers and 27% of the nonsmokers presented hypovitaminosis C. We suggest an increase in the consumption of fruits and vegetables by pregnant women, especially the smokers. <\/jats:p>","DOI":"10.1024\/0300-9831.74.3.193","type":"journal-article","created":{"date-parts":[[2006,1,31]],"date-time":"2006-01-31T12:28:58Z","timestamp":1138710538000},"page":"193-198","source":"Crossref","is-referenced-by-count":33,"title":["Concentrations of Ascorbic Acid in the Plasma of Pregnant Smokers and Nonsmokers and their Newborns"],"prefix":"10.31083","volume":"74","author":[{"family":"de Oliveira","sequence":"first","affiliation":[{"name":"Department of Nutrition, School of Public Health, University of S\u00e3o Paulo, Av.
