Studies assessing the impact of nutrition on human growth have relied on a concept of how children should grow as articulated by the continuous and slowly rising size-for-age curves found in the tool kit of every pediatrician and community health worker, known as the growth charts [1]. The variation in size among children of similar chronological age is captured graphically by percentile lines on the graphs, delineating a comparison between the relatively small, or 5th percentile child, and the relatively large, or 95th percentile child. These size differences reflect the expression of genetic and environmental factors as they interact to influence growth from the level of the cell to the whole body.
