Patterns of retarded fetal growth.

The measurement of weight, length and head circumference at birth was used to document the size and shape of infants born at term in a population where mothers are relatively short and underweight. Different patterns of intrauterine growth are proposed to explain the variation in the infant's appearance at birth. Most of the small-for-gestational-age infants were proportionately stunted. This pattern of fetal growth is probably characteristic of infants born to undernourished mothers in economically developing communities, and reflects prolonged intrauterine growth retardation.
