Recent research suggests that, aside from genetic predisposition, behavioral and environmental factors significantly influence infant health outcomes. Investigators at the Infant Care Project are seeking to identify those health risk factors observable in the first two years of life. The investigators propose that feeding and physical activity patterns established during infancy and early childhood are major determinants of later health. These patterns, in turn, are influenced by such factors as infant, caregiver and household characteristics, parenting practices, cultural beliefs, and TV viewing habits. While most previous studies have looked at white or middle-class populations, little is known about low income and minority populations. Therefore, this project examines infant care practices and how they affect infant health among low-income African-American mothers and infants in selected counties in North Carolina.
