ABSTRACT
An ecological study was conducted to examine the relation between infant morality rate (IMR) and under 5 mortality rate (UFMR) with GNP in 1993 and 1996.
The data of 145 countries were collected from WHO and UNICEF reports and we analyzed them using statistical model. First a picture of infant mortality rate and GNP was described in 7 groups of different countries with respect to WHO categorization. Then, using the data, distribution an exponential model was assumed between infant mortality rate and GNP. The effects Percentage of literacy over 15 years and total fertility rate (TFR) were adjusted using multiple regression model.
The results of data distribution showed the higher infant mortality rate corresponded with lower GNP and also the higher GNP was associated with the lower infant mortality rate, but in many countries with GNP less than 2000 $ per capita, their IMR was lower than 25/1000 living birth. The results of regression analysis showed that there was a negative significant relation between the logarithm of IMR and the logarithin of UFMR with GNP (P= 0.0001). This negative relation persisted after adjusting the percentage of literacy and TFR
Although there is a significant relation between IMR and GNP in ecological level, IMR is a better indicator of health status. It decreases only when the overall health status of population is promoted while GNP increases with accumulation among minority of population.
