[Nutrition of pregnant women working in large industrial plants].
In 1985 the dietary habits and daily food rations were analysed in 327 women in the first half, and 918 in the second half of pregnancy working, similarly as 921 non-pregnant healthy women, in 42 biggest Polish industrial plants as manual workers. The energy level (2623 kcal), total protein (75.3g) and the levels of the remaining nutrients in the daily food ration in women in the first half of pregnancy were either in agreement or higher (in the case of fats--108.5g) than the recommended ones, with the exception of calcium (669 mg) and percent of energy derived from protein (11.6%) which were lower. The mean daily food ration of women in the second half of pregnancy provided a sufficient amount of energy (2759 kcal), lower than recommended amount of total protein (79.9g), calcium (734 mg), and iron and vitamins B1, B2 and C. Pregnant women in relation to controls consumed significantly more energy daily (by 684 kcal in the first half--35%, and by 820 kcal--42% in the second half of pregnancy) and various nutrients, with the exception of vitamin C in the first half of pregnancy (p less than or equal to 0.05). In the second half of pregnancy the women took significantly more energy, total protein, animal protein, carbohydrates, calcium, iron and vitamin B1, B2 and C than in the first half (p less than or equal to 0.05). These differences were not statistically significant for the remaining nutrients. The study demonstrated that women in pregnancy took significantly different diets than non-pregnant women.
