Interpretive Summary:

Technical Abstract: To determine whether dietary nutrients are diverted away from milk production (MP) to support maternal growth, we measured body composition, dietary intakes, and MP in 12 lactating (L), 11 nonlactating postpartum (NL), and 11 nulliparous (NP) adolescents at 6 and 24 wk postpartum. Lean body mass (LBM) and body fat (FAT) were determined by 40K counting. Protein n(P) and energy (E) intakes were estimated from 3-d food records using a nutrient database. MAMT was determined by test weighing. Results (mean +/- SD, *P<0.05) are shown: Time (wk) 6 wk postpartum 24 wk postpartum Group L NL NP L NL NP LBM(kg) 36+/-7* 39+/-5 38+/-5 38+/-6 39+/-6 38+/-6 Fat(kg) 22+/-6* 22+/-7 15+/-5 19+/-6 20+/-9 17+/-7 E(kcal/d)2380+/-590* 1670+/-460 1860+/-470 1770+/-660 1600+/-390 1870+/-520 0P(g/d) 84+/-30* 51+/-15 62+/-14 65+/-20 51+/-7 65+/-19 MAMT(g/d) 531+/-164 -- -- 314+/-94 -- -- LBM increased and FAT decreased in the presence of reduced MP in L adolescents. The increased dietary P and E intakes of L adolescents may be used to support the catch-up growth of maternal body stores.
