Background & Aim: Preterm birth (PTB) and low birth weight (LBW) which amongst common adverse pregnancy associated with newborn morbidity and mortality. Socio-demographic as well as maternal factors influence PTB and LBW. To date, data on factors contributing to adverse pregnancy outcomes in Sivas, Turkey are limited. This study aimed to estimate the prevalence of PTB and LBW in Sivas and their associated factors in women of childbearing ages. Materials & Methods: The population-based survey involved 1273 women were conducted in Sivas center, Turkey, between September 2013 and May 2014. Odds ratios with 95% confidence intervals of LBW/PTB for a range of socio-demographic and maternal factors were estimated using multivariate logistic regression analysis. Results: The overall prevalence of PTB and LBW were 16.3% and 17.7% respectively. Maternal low educational level (odds ratio, or = 4.25 for PTB and or = 4.93 for LBW) as well as being unemployed (OR = 2.08 only for PTB), being a smoker (OR = 1.37 for PTB and or = 1.67 for LBW), being a multiparous women (OR = 2.59 for PTB and or = 3.79 for LBW) and having a low income level (OR = 1.53 only for LBW) were the factors associated with the PTB/LBW. Conclusion: The results suggest that the rates of PTB/LBW were common in Sivas. Low education and income levels, smoking, unemployment and multiparity are the risk factors for PTB/LBW and should be addressed to reduce PTB and LBW and improve health of women of childbearing age.
