Determinants of weight and length of Indonesian neonates

Design: From 16-20 week of pregnancy, 366 mothers of the neonates had participated in the community-based study to investigate the effect of weekly supplementation during pregnancy with iron and vitamin A on infant growth. Women from five villages were allocated randomly to receive two tablets each containing 60 mg iron as ferrous sulphate and 250 ?g folic acid (n=121) or two tablets each containing 2400 RE vitamin A in addition to the same amount of ferrous sulphate and folic acid (n=122). A third ('daily') group (n=123) participating in the national iron supplementation programme was recruited from four neighbouring villages. Results: Neonatal weight and length did not differ between the two weekly groups and between the weekly iron group and the 'daily' group. Iron and vitamin A status during pregnancy did not influence neonatal weight and length significantly. Boys were 100 g heavier and 0.53 cm longer than girls (P<0.05). First born neonates were lighter (P
