[Relation between nutrition of pregnant women and small-for-gestational age infants].
A nutritional investigation was carried out both on small-for-gestational age infants (SGA) group and on normal pregnancy (control group). 60 cases were collected in each group. The results revealed that Quatlet index (32.09 +/- 2.39), calorie intake at 2nd (9.49 +/- 1.51 MJ/day) and 3rd (10.08 +/- 1.11 MJ/day) trimester of pregnancy, serum albumin (36.2 +/- 7.9 g/L), prealbumin (0.27 +/- 0.07 g/L) and glucose (4.17 +/- 0.98 mmol/L) levels in SGA group were lower than those in control. Serum Cu and Zn levels showed no significant difference between the 2 groups. The main reasons of low calorie intake were due to prolonged pregnant hyperemesis (44.83%) and bad habits in diet (31.03%). Serum glucose and prealbumin levels in cord blood were highly correlated with those in maternal blood. A significantly positive correlation between birth weight and maternal calorie intake, serum glucose and prealbumin levels was found. It proposed that serum prealbumin level could be used as a mal-nutritional index of pregnancy. Calorie and qualified protein supplement was necessary for women with prolonged pregnant hyperemesis or bad diet habits.
