摘要:This retrospective and cross-sectional study on trends of Low Birth Weight (LBW) as observed in selected healthfacilities in Ogun state, Nigeria, covered the period 1991 – 1999, with reference to the World Summit for Children(WSC) target for the 1990’s. LBW is a serious threat to survival of infants in both perinatal and neonatal periods,and to normal physical and mental development in the post natal period. The study was carried out to determinehow far the WSC goal of reducing the LBW incidence to 10% by the year 2000 has been achieved, and also to gainan understanding on the determinants of LBW in the study area. Data were generated from five randomly selectedhealth facilities (three rural and two urban), with a total of 33,321 deliveries having fairly complete antenatalrecords during the study period. Out of this number, 5,598 cases of LBW deliveries were extracted. The dataobtained were analysed using SPSS package version 14.0. The overall incidence of LBW was 16.8%. A regressionmodel further showed the percentage contribution of sex of baby (r2 = 0.43), maternal height (r2 = 0.41) maternalage (r2 = 0.27) and parity (r2 = 0.09) to observed LBW incidence. The findings from this study showed an almostconsistent departure from the WSC target and explained why Nigeria did not attain the WSC goal. Adolescentnutrition and reproductive health behaviours, measures for improved pregnancy outcomes and reversal of negativeimplications of LBW incidence in Nigeria, must be effectively addressed.
