Interpretive Summary:

Technical Abstract: To determine if maternal milk production (MP, g/d) was associated with the adequacy of maternal nutrient intake or body nutrient stores, dietary energy (EI, kcal/d) and protein (PI, g/d) intakes; body weight (WT, kg), lean body mass (LBM, kg), and body fat (BF, kg); and MP were determined at 6-wk and 12-wk postpartum from 3-d food records in 11 lactating (L), 12 nonlactating postpartum (NL), and 11 nulliparous (C) adolescents. Results (mean+/-SD) are shown: Time Postpartum 6wk Postpartum 12 wk Group L NL C £ L NL C WT 57+/-9 59+/-11 54+/-8 £ 55+/-7 58+/-14 54+/-8 LBM 36+/-6 39+/-8 37+/-6 £ 37+/-7 40+/-7 37+/-7 BF 21+/-7 20+/-6 17+/-5 £ 18+/-3 18+/-7 17+/-6 EI 2245+/-583 1801+/-492 1878+/-455 £ 2146+/-539# 1622+/-420 1541+/-306 6PI 79+/-28* 55+/-20 63+/-13 £ 84+/-31# 50+/-16 50+/-15 MP 508+/-208 - - £ 423+/-177 - - *p less than 0.05 L vs NL; #p less than 0.05 L vs NL and C When adjusted for WT, MP at 6-wk, but not 12-wk, postpartum showed a significant positive association with PI and LBM and a significant negative association with BF in L adolescents. These data suggest that the adequacy of the maternal diet and body nutrient stores are essential for successful lactational performance in the adolescent at 6-wk postpartum.
