%X we assessed changes in body composition in lactating adolescent mothers living under unfavorable socioeconomic and sanitary conditions. a total of 17 healthy primiparous adolescents under 17 years of age attending the maternity hospital of the city of la plata, argentina, were followed at 4 time points (15 days and 3, 6 and 12 months postpartum) to assess, a) dietary intake, b) practice of physical activity, c) nutritional condition (weight, height, body mass index; bmi; according to age, and body composition by the sum of skinfold measurements), d) characteristics of lactation, and e) growth parameters of the child. the mean age of adolescents was 15.06 ¡À 0.66 years (mean menarchal age, 11.59 ¡À 0.80 years). all adolescents breastfed up to 12 months postpartum, and maternal milk covered above 80% the baby intake (mean 7.06 ¡À 2.54 breast feeds/day). while the daily intake of nutrients by adolescent mothers was constant up to 6 months postpartum, there was a modest decrease in that of proteins, carbohydrates and lipids 15 days and 12 months postpartum. the decrease in energetic intake during the same period was significant (p< 0.05). the practice of physical activity was classified as moderate during the follow-up period. whereas mean basal percent of fat body mass (fbm) was 29.85 ¡À 2.87, and decreased significantly at 6 (27.2% ¡À 3.9%; p= 0.02) and 12 (26.1% ¡À 3.9%; p=0.002) months postpartum, changes in lean body mass (lbm) were not significant. in conclusion, lactating adolescents maintained lbm, whereas weight, fbm and bmi decreased markedly from 3 months postpartum.
