Low birth weight as a risk factor for infant mortality in Egypt.

We examined the risk of infant mortality among low-birth-weight children (< 2500 g) controlling for other risk factors of infant mortality. We used survival regression analysis on 11,361 childbirths in the 5 years preceding the 2000 Egypt Demographic and Health Survey. Higher birth order; shorter birth interval; lack of prenatal care, safe sources of drinking-water and hygienic toilet facilities; living in urban residence and Upper Egypt rural region were associated with a higher isk of infant mortality. The multivariate model indicated that low-birth-weight children were about 3 times more likely to die in infancy than other children (hazard ratio = 2.89, 95% CI: 2.33-3.58) independent of other risk factors.
