Socio-demographic characteristics and obstetrics information of the pregnant women were collected using pretested questionnaires. Anthropometric measurements were carried out using appropriate measuring instruments. All statistical analyses were performed using SPSS version 20. Multiple linear regressions analysis was also performed to explore independent effects of maternal factors. A p value< 0.05 was considered to be significant.
