Birth weight was obtained from hospital records. Other birth and subsequent (3, 12, and 24 months) anthropometry measures were performed by three trained paediatric research nurses. Weight was measured to the nearest 1 g using a Seca 757 electronic baby scale and length was measured to the nearest 0.1 cm using an Infantometer (SECA 416). Skinfold thickness was measured in triplicate at four sites (triceps, subscapular, flank, and quadriceps) on the left side of the body using a Holtain Tanner/Whitehouse Skinfold Caliper (Holtain Ltd).
