Extreme infant’s birthweights have short and long-term effects on the health of infant and mother leading to complications causing neonatal deaths and or maternal deaths. We use quantile regression analysis which is robust against extreme values to estimate the relationship of with conditional on quantiles (or percentiles) of by modeling the entire distribution of the response variable. In this work, we model the birthweight of infants on related maternal factors, using quantile regression where the results show that different factor combinations are significant at different levels of the quantiles; at maternal height, no prenatal care and pregnancy complications were all statistically significant ( ); at , maternal weight, no prenatal care, 1st visit at 3rd trimester and pregnancy complications were found to be statistically significant with ( ); and at , maternal weight and education level 3 are statistically significant with . These results indicate the performance of the quantile regression in assessing the entire distribution of the infant’s birthweight.
