عوامل اجتماعی-فرهنگی موثر بر مرگ و میرهای ناشناخته در بین نوزادان زیر یکماه در استان های تهران و مرکزی

In this work, the net effect of birth type (one or more children), the number of previous dead children, the mother tongue, mother's age at infant birth, number of deliveries, consanguineous marriages, and the father's education on the mortality of one-month-old infants in families of residents of Tehran and the Central Province is studied. The data referred to in this study was taken from a survey conducted by the Department of Vital Statistics in 1991. Applying multiple logistic regreession to analyze the data I removed the effect of a number of variables to conclude that the consanguineous marriage is significantly effective by itself and in interaction with the number of previous dead children. The odds ratio among consanguine parents for those who had one previous dead child to those without a previous dead child is 5.45. This ratio for non-consanguineous parents is 4.96. Thus the significant effect of consanguinity is proven.
