Nutritional survey of pregnant women in Hungary.

A nutritional survey of a Hungarian group of pregnant women was carried out. One hundred and twenty nine women aged 25.9 years, entered the study, but only 70 completed all the protocol. Average body weight gain was 12.4 kg and the mean birth weight of the newborns was 3,386 g. Mean energy and nutrient intakes of pregnant women showed similar patterns as in Hungarian non-pregnant women of the same age. The mean energy intake was high (11 MJ), being 10% higher than for non-pregnant women. The mean protein and lipid intakes were also high, 91.9 g and 108.4 g, respectively, exceeding by 7% and 6% the intakes of the non-pregnant women. Dietary intakes of saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs) were close to 12% of energy, and the intake of polyunsaturated fatty acids (PUFAs) was 7.6% of total energy. Palmitic acid (16:0), oleic acid (18:1 n-9) and linoleic acid (18:2 n-6) made the greatest contribution to the total peak area of SFAs, MUFAs, and PUFAs, respectively. The ratio of P/S (polyunsaturated/saturated fatty acids) was appropriate: 0.65; however, the ratio of linoleic acid (18:2 n-6), to linolenic acid (18:3 n-3) was high: 16. The cholesterol intake was somewhat lower in pregnant than in non-pregnant women. Complex carbohydrate intake was low (245 g) but it was still by 75% higher than in non-pregnant women. The excess sodium intake (6.3 g) was very similar to that of non-pregnant women. Mean values for retinol, tocopherol, ascorbic acid, cobalamin and copper intakes were higher than the Hungarian Recommended Dietary Allowances (RDA). Thiamine, riboflavin, pyridoxine, niacin, calcium, iron and zinc intakes were insufficient. Data showed an imbalance in the energy and nutrient intakes of Hungarian pregnant women, and this could be harmful for both the mother and pregnancy outcome.
