title: Anthropometric predictors of low birth weight outcome in teenage pregnancy.
abstract: The highest relative risks of low birth weight are found among births to teenage mothers. An analysis of anthropometrics (weight, mid-arm circumference, and triceps skinfold) among black teenagers attending an adolescent prenatal program was studied. The sample consisted of 100 girls under 17 years. Data were collected from 19 to 35 weeks gestation. Adolescent mothers who delivered low birth weight (LBW) infants demonstrated different patterns of anthropometric changes than teen mothers who delivered normal birth weight (NBW) infants. Mean mid-arm circumference increases in the LBW group (0.05 mm/wk) were significantly less than mean increases in the NBW group (0.80 mm/wk) (p less than 0.05). Arm fat area estimates of the LBW mothers demonstrated weekly depletion (-24.9 mm2/wk), which was significantly less than those of the NBW group, who accumulated fat (+15.3 mm2/wk) (p less than .05). Changes in maternal nutritional status may in part mediate the birthweight outcome in adolescent pregnancy. Anthropometrics may be useful in predicting those teens at highest risk of bearing LBW infants.
