Inequalities in Income and Health Related to Child Poverty—Reply

JAMA. 2009;301(22):2328-2329. doi:10.1001/jama.2009.770

In Reply: Mr Siegel raises 4 substantive points in relation to my Commentary to which I would like to respond. First, contrary to what is implied, there is a close correspondence between the Gini coefficient and relative child poverty rates in high-income countries1 (r = 0.78, P < .001 in the countries covered in the Commentary). Relative child poverty was used because Gini coefficients were available for fewer countries and for time periods less contemporaneous with child mortality data. The linear association between Gini coefficients and child mortality was also statistically significant (n = 18, adjusted r2 = 0.73, P < .001).
