Impact of Socioeconomic and Health System Factors on Infant Mortality Rate in Organization of the Petroleum Exporting Countries (OPEC): Evidence from 2004 to 2013

infant mortality rate is one of the main health indicators for assessing the health system’s performance over the world. We aim to examine the socioeconomic and health system factors affect infant mortality in OPEC from 2004 to 2013. was used to examine the effects of some of the key explanatory factors (total fertility rate per women, GDP per capita (current US$), public health expenditure as % of total health expenditure and female labor force participation rate) on infant mortality in OPEC from 2004 to 2013. These data were obtained from World Bank and World Health Organization data bank. our results showed the total fertility rate had a positive and significant impact on infant mortality in the studied period. Also, there are negative significant associations between GDP per capita and public health expenditure with infant mortality. We did not observe any relationship between infant mortality and female labour force participation rate in the studied countries from 2004 to 2013. total fertility rate per women, GDP per capita (current US$), public health expenditure as % of total health expenditure were identified as the main factors affecting on infant mortality in OPEC over the ten years (2004-2013). This study enables health policy-makers to better understand the factors affecting on infant mortality and thereby take necessary steps in managing and decreasing the infant mortality rate in the studied countries.
