Maternal risk factors for low birth weight and intrauterine growth retardation in a Guatemalan population.

Hospital data on 306 mother-infant pairs in Cobán, Guatemala, were studied to assess factors responsible for low infant birth weights involving the two general kinds of intrauterine growth retardation (IUGR), these being Type I (symmetric stunting) and Type II (asymmetric stunting or wasting). The results indicate that the Type I IUGR observed arose primarily from long-term poverty, malnutrition, and chronic poor living conditions, while much of the Type II IUGR seemed attributable to maternal disorders affected by short interbirth intervals.
