Levels and Determinants of Low Birth Weight in Infants Delivered Under the National Health Insurance Scheme in Northern Ghana

This research determined the levels and odds ratios for low birth weight (LBW) infants delivered under the National Health Insurance Scheme (NHIS) compared to LBW infants delivered under the previous "Cash and Carry" system in Northern Ghana. Birth records of infants delivered before and after implementation of the NHIS in Northern Ghana were examined. Records of each day's births during the identified periods were abstracted. Days with fewer or no births were accommodated by oversampling from days before or after. Chi squared tests of independence were used to examine the bivariate association between categorical independent variables and LBW. Multiple logistic regression models were used to examine the relationships among selected variables for mothers and infants and the odds ratios for LBW. Infants delivered under NHIS had lower rates of LBW (16.8 %) compared to infants born under Cash and Carry (23.3 %). Mothers who delivered under NHIS were significantly less likely to have infants at LBW (unadjusted OR 0.65; 95 % CI 0.49, 0.86). The rate of LBW among infants delivered under NHIS is significantly lower than among infants delivered under Cash and Carry. The rate of LBW under Cash and Carry in 2000 fell by 27 % in relation to the NHIS in 2010. These findings confirm that the NHIS, which gives pregnant women in Northern Ghana four antenatal visits and access to skilled health professionals for delivery at no cost to the mother, significantly improved birth weight outcomes.
