This study aims to determine serum folate and plasma homocysteine levels in healthy pregnant women following a live birth and compare them with healthy non-pregnant women. Fifty healthy gravid multiparous women are included in the study and 25 normal non-pregnant female subjects act as controls (group I). The pregnant women are divided into two groups according to interpregnancy interval: group II (six months or less): group III (18-24 months). Venous blood samples are analysed for red blood cell folate and homocysteine, vitamin B12, serum folate and albumin, and serum aminotransferases (ALT and AST). There was a significant decrease in red cell folate and serum folate in group II compared to the control group (P<0.001). Serum vitamin B12 showed no significant difference. Plasma homocysteine and serum albumin showed significant decreases in both groups II and III compared to the control group. (P<0.001) There was significant positive correlation between homocysteine and serum albumin in the three studied groups. (r = 0.42, P<0.001; r = 0.45, P<0.001: r = 0.51, P<0.001, respectively). There was significant negative correlation between red cell folate and homocysteine in the three studied groups. (r = -0.48, P<0.001 : r = -0.53, P<0.001;r = -0.49, P<0.001, respectively). Two cases in group II showed signs of intrauterine growth retardation. The results suggest that pregnant females with short interpregnancy intervals are more likely to develop folate deficiency. Educational strategies are required to increase folate awareness among women to promote the benefits of folio acid supplementation. Mandatory folate fortification of foods should be defined and monitored.
