title: [The influence of smoking during pregnancy on decresed vitamin C concentration in blood serum].
abstract: There are reports about decreased vitamin C concentration in blood serum of smokers. In pregnancy decreased vitamin C concentration in blood serum is observed as well. The aim of this study was to analise vitamin C concentration in blood serum of pregnant women in two periods of pregnancy (20-22 and 38-41 week), in smokers and non-smokers and its comparision to our own results from researches made 25 years ago. Vitamin C concentration was determined by using Roe and Kuether method, in groups of 20 prgnant women being in 20-22 and 38-41 pregnancy weeks, smoking over 10 cigarettes per day and non-smoking. Because most of pregnant were using recommended vitamins, only these were qualified for research, who were taking multivitamin supplements including vitamin C in daily dose from 100 to 180 mg. Statistical analysis of the results was made by using t-Student test with changeability for p < 0.05.
  
  
  RESULTS
  average vitamin C concentration in pregnant woman blood serum smoking over 10 cigarettes per day in 20-22 week of pregnancy was 1.43 mg% and in 38-41 week was 1.35 mg%. This concentration is much higher than that compatible from 25 years (0.51 mg% in both 20-22 and 38-41 week of pregnancy). Vitamin C concentration in non-smoking pregnant woman blood serum are higher now as well. These diffrences should be explained by taking multivitamin supplements widely recommended during pregnancy, by education and promotion of healthy living, by improvement of socioeconomic and environmental conditions. However the fact of harmful influence of cigarette smoking on vitamin C concentration in pregnant woman blood serum is still clear.
