Low birth weight incidence in Lundu, Sarawak.

The overall mean birth weight of the total deliveries (1986-1988) in Lundu Hospital was 2.96 kg. The mean birth weight for the male babies was 2.94 kg. The Chinese babies had a significantly higher mean birth weight (3.12 kg) than the other ethnic groups (p < 0.05). The overall incidence of low birth weight (LBW) in this study was 11.84 per cent. The Chinese again had a lower incidence of LBW of 6.73 per cent compared to Ibans who had the highest incidence of LBW, 13.59 per cent, with the Bidayuhs 12.97 per cent and Malays, 12.45 per cent. It was also noticed that of the 14.9 per cent preterm deliveries, 37.5 per cent were LBW. The very young mothers (15-19 years) and older mothers (> 40 years) seem to have a higher incidence of LBW. Mothers who had medical conditions like anaemia, hypertension, pre-eclampsia also had a higher incidence of LBW when compared to mothers who did not have a medical condition. Special emphasis should be given to mothers who have medical conditions, and to very young and very old mothers during antenatal care, to prevent incidence of LBW.
