Supplement to Longitudinal analysis of early childhood stunting in low-resource settings

Chapter 4 Assessment of potential secular trends

This study included cohorts that measured child growth from 1969 to 2014. To assess potential secular trends, we plotted the mean length-for-age Z-score (LAZ) over time. The plot below shows the individual observations from included studies over this range of years. There does not appear to be a secular trend in LAZ.
