MLPTI have higher fat mass percentages at 2 years CA compared to the literature on term-born infants, while FMI was within range, and fat-free mass index (FFMI) was relatively low. This suggests an altered body composition with reduced fat-free mass instead of excess fat accumulation. This highlights the need for more research on body composition, feeding practices, and cautious weight gain in MLPTI.
Lafeber et al. (2026) studied this question.
