Abstract
This research examines associations between various measures of child growth (height, weight, triceps skinfold thickness, subscapular skinfold thickness), dietary variables, and poverty status in a sample of 13,750 black and white children aged 1 to 17 yr. The data used in this survey were collected in the National Health and Nutrition Examination Surveys I and II (HANESI, 1971–1975, and HANESII, 1976–1980). In general, lower mean values for all the growth measures examined were found in children living below the defined poverty threshold in comparison with those above the poverty threshold. The magnitude of these poverty-associated differences tended to decrease between the times of the HANESI and HANESII surveys, though not sufficiently to be statistically significant. These differences in growth were not consistently associated with differences in dietary intake of energy between poverty groups or surveys.
