  1. Multivariable logistic regression analysis with adjustment study design effect and risk factors. Risk factors were included: marital status, height, pre-exiting medical conditions, maternal hypertension, birthweight and health institutions ownership. Pre-exiting medical conditions was defined as presence of any of followings: chronic hypertension, cardiac/renal diseases, chronic respiratory conditions, diabetes mellitus, sickle cell anaemia, severe anaemia and pyelonephritis or urinary infection. Maternal hypertension was defined as presence of pregnancy-induced hypertension, preeclampsia and eclampsia
