Introduction: The evaluation of newly born infants, by birth weight in relation to gestational age, parity number, and age of the mother for the purposes of checking the impact of maternal characteristics on the baby size especially for monitoring and evaluating mother and child health programs are of great interest to health management researches. Aim: The aim of the study is to obtain a model for predicting birth measures (weight, height, head and chest circumference), at the time of delivery to help in giving the medical aids to the mother and child on time; and to prevent childbirth complications that endanger baby’s and mother’s life. Materials and methods: Total 970 delivery cases were studied, 2 registered nurses as interobserver for physical measurement for each newly born baby were assigned. The ‘Central Limit Theorem’ technique has been used as a model for prediction of newborn babies at the time of delivery. Results: An increase in the birth weights positively correlated with an increase in gestational age increases; increasing the number of pregnancies one expects the increase in birth weight; and, dropout rate of birth measures among children born to mothers of low socio-economic class, hence higher the level of development and standard of living, the higher the birth weight. Conclusion: It provides a substantial data for health policy and decision makers over a few maternal characteristics on the weight, head and chest circumference of the newborns in the northern portion of Jordan which are clearly not accessible to bridge the gap between what is needed and the genuine far-reaching selection of clinical hones to encourage secure conveyance cases in consonance with local and applied standard birth measures.
