Abstract

Male and female infants from rural Ethiopia were tested to investigate relations among hemoglobin (Hb), anthropometry, and attention. A longitudinal design was used to examine differences in attention performance from 6 (= 24.9 weeks, = 89) to 9 months of age (M = 40.6 weeks, = 85), differences hypothesized to be related to changes in iron status and growth delays. Stunting (length-for-age z scores < −2.0) and attention performance, t(30) = −2.42, = .022, worsened over time. Growth and Hb predicted attention at 9 months, R2 = .15, < .05, but not at 6. The study contributes to the knowledge base concerning the relations among Hb, early growth, and attention.
