Age-profiles of height-for-age z-scores. Unconditional, flexible plots of z-scores across age groups for children living in polygamous and monogamous households. In both groups there is evidence of deteriorating z-scores as children grow older. These cross-sectional patterns are suggestive of growth faltering, in line with previous large-scale microstudies (5). Starting at the age of 20 mo, children residing in monogamous households show relative faster signs of recovery. These patterns are in line with lower z-scores among polygynous children in Table 1. Smoothed means by local polynomial regression using the lpoly command in STATA 13.
