Factors associated with birthweight in Bahrain.

The birthweights of 6793 infants, based on birth notification forms, were analysed to determine the influence of sex, geographical location, mother's nationality, mother's age, interval between births and number of past deliveries on the birthweight distribution. It was found that these factors contributed significantly to birthweight of the newborn, except for the mother's nationality and the number of past deliveries which were not significant contributory factors.
