The researchers have available a unique sample of 2,884 adult (primary mother)/child pairs, surveyed during 1999-2000, who represent a low-income, multi-ethnic population of participants in the New York WIC Program. The authors have identified child eating patterns and parent characteristic behaviors that are associated with child obesity. Because these children have their height and weight routinely measured by WIC staff every 6 months, they will be followed prospectively to assess change in adiposity over time. The researchers will evaluate the extent to which these identified factors are prospectively related to the incidence, remission and/or persistence of obesity. At the conclusion of this research project, eating patterns and dietary behaviors that predict or prevent child obesity will have been identified. These findings will help guide future obesity prevention recommendations.
