    Despite the high prevalence of low birth weight infants in sub-Saharan Africa and the associated poor outcomes, weight change during the newborn period has not been well characterized for this population. We prospectively assessed growth over the first 30 days among 120 infants born < 2000 g (g) in Guinea-Bissau and Uganda, and compared it to a similar cohort of 420 infants born ≥ 2000 g. Among those born < 2000 g, mean birth weight was 1747 ± 164 g, and initial weight loss was 8.25 ± 4.40% of birth weight prior to the initiation of weight gain at a median of 3 (interquartile range 2, 4) days of age. This initial weight loss was more pronounced (8.25 vs 6.06%; p < 0.001) and lasted longer (median 3 vs 2 days; p < 0.001) than for infants born ≥ 2000 g. The initial period of weight loss was an important predictor of growth at 30 days in both cohorts. Infants born < 2000 g on average grew proportionately to their size at birth but did not experience catch-up growth; their weights at 30 days remained much lower than that of infants born ≥ 2000 g and most remained severely underweight. Targeted interventions to optimize early growth should be investigated. MEDLINE - Academic
