Young age at childbearing (≤19 years) is common and associated with poor birth outcomes. A trial among Malawian pregnant women with moderate malnutrition was used to determine outcomes of young adolescents (≤18 years), older adolescents (18-20 years), and adults (>20 years). Women received one of three supplementary foods that provided ∼900 kcal/day and 33-36 g protein/day and returned every 2 weeks. Newborn/maternal measurements were taken at delivery and after 6 and 12 weeks. Upon enrollment, adolescents had greater body mass index than adults (19.9 ± 1.3 versus 19.5 ± 1.4 kg/m2 , P < 0.001). Young adolescents received more rations of food and enrolled and delivered with a lower fundal height than adults (21.7 ± 5.2 versus 23.0 ± 5.6, P = 0.00 enrollment; 30.2 ± 3.1 versus 31.0 ± 2.8, P < 0.001 delivery). Among newborns, length for age was lowest in young adolescents, greater in older adolescents, and greatest in adults (Z-scores -1.7 ± 1.2, -1.4 ± 1.2, and -1.1 ± 1.1, respectively; P < 0.001). These differences persisted in length for age at 6 and 12 weeks of age for infants. Adolescents enrolled earlier in pregnancy and appeared more nutritionally adequate than adults; adolescent outcomes were inferior to those of adults, suggesting that they were subject to more physiologic stressors and/or different nutritional needs.
