Abstract
The aim of this paper was to investigate whether socioeconomic factors such as parent's education, occupation, and income constitute risk factors in perinatal mortality after controlling for biological variables such as birth weight and length of gestation, and maternal factors such as age, parity and reproductive history. A case-control study covering all perinatal deaths in Kuwait was conducted for one year from 1 October, 1997 to 30 September, 1998. Each case (perinatal death) was matched with a control (live birth). Matching criteria were: father's nationality, place, and date of birth. Information was successfully collected on 463 matched pairs, 274 Kuwaitis and 189 non-Kuwaitis. Only singleton births were included in the analysis. Bivariate analysis showed that several of the socioeconomic variables (e.g. lower education, lower income) increased the risk of a perinatal death. However, none of these variables remained significant in the multivariate analysis in which birth weight and length of gestation emerged as the two major determinants of perinatal deaths among both nationality groups. Among the Kuwaitis, primiparity and high parity, and previous history of miscarriage were also significant risk factors. Among the non-Kuwaitis, none of the socioeconomic factors, or the maternal factors, were significant predictors of perinatal mortality. For Kuwaitis, it appears that the government's policies and programs aimed at reducing social inequalities in the society have been effective in eliminating perinatal mortality differences between socioeconomic groups. Among non-Kuwaitis, the lack of differences is reflective of the fact that this group is relatively homogenous and selective of the more affluent who can bring the family to Kuwait. Both nationality groups benefit from the government's free health services. However, charges for non-Kuwaitis are due to be levied soon which may increase disparities in access to health care.
