Linking Activity, Nutrition, and Child Health

Brief summary (registry, in English)

Leading health organizations have identified prevention of obesity in young children as a critical public health challenge. Low levels of physical activity and high levels of sedentary behavior may contribute to the development of excessive fatness in young children, but these relationships have not been fully explored, and accelerometry rarely has been used to measure physical activity levels in infants and toddlers. No previous study has used accelerometry as an objective measure of physical activity in young children as they develop from infancy to preschool age. Accordingly, little is known about the factors associated with the development of physical activity behavior in very young children, and little is known about the influence of physical activity and sedentary behavior, measured objectively, on development of weight status during the transition from infancy to age 3. The first aim of this study is to describe physical activity and sedentary behavior in young children as they develop from infancy to preschool age. The second aim is to describe the longitudinal associations of weight status with physical activity and sedentary behavior as young children develop from infancy to preschool age. The proposed investigation will employ a longitudinal, observational study design. Participants will be 160 children and their biological mothers living in Columbia, South Carolina. For each participating child, measurements will be taken at 6, 12, 18, 24, 30, and 36 months of age. At each time point, each child's physical activity, sedentary behavior, weight status and motor developmental status will be measured objectively, and each child's mother will complete a survey to assess demographic, social and physical environmental factors; gross motor milestones; parenting practices related to physical activity and sedentary behavior; and dietary practices. Childcare center directors will complete a survey annually to assess center characteristics, and the Environment and Policy Assessment and Observation (EPAO) will be administered in the child's classroom annually.
