Project Number: 6250-51000-047-00
Start Date: May 21, 2004
End Date: Mar 30, 2009
Survey instruments will be constructed/validated to determine different groups of populations’ association between the perceived barriers and facilitators and actual DGA adherence. 1) Biological Influences on Children's Diet & PA - Integrate how biological & psychosocial variables influence diet & PA using the sensitivity to bitter taste (PROP), as a biological influence on dietary intake; and adiposity, as a biological influence on PA. 2) The Development & Testing of Interventions to Promote Healthy Dietary Behavior among Youth for Chronic Disease Prevention - Evaluate related dietary interventions with children. 3) Family Influences on the Development of Food Intake Regulation - Will be determined through observational measures of mother-infant feeding interactions as well as a weighed food intake protocol to measure infants' energy regulation. 4) Relationships between Infant Feeding Patterns & the Development of Risk Factors for Obesity, CV Disease & Diabetes in Early Childhood - Through a prospective examination of relationships between feeding patterns in the first year of life & risk factors for obesity, heart disease & metabolic syndrome later in childhood. An instrument for characterizing early infant feeding behavior in different ethnic groups will be developed & validated. Infant body composition will be measured within 2 weeks of birth, every 6 months through the 2nd year of life, and yearly thereafter. Maternal and parental body composition will be measured. Weighed diet records will be obtained using data collected by parents and day care providers, and parental control of feeding behavior will be assessed at birth, 1 year, and 3 years of age. 5) Investigation of Dietary Intakes of Children - Conduct sophisticated analyses of the eating patterns & diet quality of 1243 children and 1840 young adults as they relate to obesity, using the Bogalusa Heart Study database compiled from 1973-96 surveys. 6) Dietary and Genetic Interactions of Isothiocyanates - Undertake an approach to advance present methods for measuring dietary intake of isothiocyanates & metabolic activity they induce. This will provide specific targets for preventative and therapeutic interventions that will be particularly important to older children. 7) A Longitudinal Study of Athletic Self-Concept & Physical Activity Behavior in Children & Adolescents - Obtain student measures on a Athletic identity questionnaire, utilizing activity monitors, evaluating parental measures and gaining an insight into the teacher measures for the child. 8) Prevention & Treatment of Obesity in Children - Develop a data collection protocol for future studies, and review datasets to understand correlations between socioeconomic status, dietary intake, & media as they relate to obesity. 9) Predicting & Explaining Youth PA Behavior - Literature review will permit an understanding of variable definition and will permit scale construction. Cognitive interviews will initiate the pilot testing of the scales followed by an analysis utilizing 500 participants.
