This paper examines the effect of consanguineous marriages on infant and child mortality in Egyptusing country’s Demographic Health Survey 2000 data - a nationally representative sample of16957 households from six governorates of Egypt that includes 15573 ever-married women aged15-49. To see clearly the impact of consanguinity on offspring’s mortality, the group of womenhas been divided into three separate categories, namely, ‘close consanguineous’, ‘remoteconsanguineous’ and ‘non-consanguineous’ marriages. Multivariate logistic regression modelshave been used with ‘infant mortality’ and ‘child mortality’ as dependent variable and controllingfor other selected socio-economic variables that are known to affect the dependent variable. Theresults show 30% and 19% higher risk of infant mortality among close and remoteconsanguineous couples, respectively. Similarly, the risk of child mortality is found higher amongthe close consanguineous couples by more than 50% and among remote consanguineous couplesby 27% as compared to non-consanguineous unions
