Research Project: Effects of Diet and Physical Activity on Maternal/Child/Adolescent Health and Development

Location: Arkansas Children's Nutrition Center

Project Number: 6026-51000-010-06-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Jul 1, 2017
End Date: Sep 30, 2019

Objective:
The mission of Cooperator's Arkansas Children’s Nutrition Center (ACNC) is to determine the effects of diet, physical activity and nutritional status in childhood and in mothers during the pre- and post-conception periods on growth, development and health by conducting research on: 1) central nervous system and cognitive development and function of infants and children; 2) roles of maternal and child body composition, metabolism and genes (including responses to food macronutrients, phytochemicals and microbe-derived factors) on infant and child growth, development and the long-term health consequences of these factors; and 3) impact of parental and child physical activity on these parameters, singly or in combination with diet, and the biological basis for exercise-associated behaviors and health outcomes. To accomplish this mission, the ACNC has the following objectives and as appropriate, others as mutually agreed upon: A. Determine how maternal/parental diet, exercise, and metabolic health associate with psychological/behavioral, neurologic and physiological function and development in children. B. Understand how postnatal diet, childhood physical activity, and nutrition associate with psychological/behavioral, neurologic and physiological function and development in children. C. Characterize the interaction between the microbiome, host health and nutrition to modify physiology and promote health and development (skeleton, gastrointestinal and hepatic tissues, immune system, cardiovascular, and muscle, e.g.).

Approach:
To accomplish these objectives, a research plan encompassing the specific research described below is authorized. Research is to be accomplished over a multi-year period as resources are available and as readiness for research and management capabilities develops. The plan shall be divided into the following areas: A. Determine how dietary components, dietary patterns, and metabolic health influence psychological-behavioral outcomes, neurodevelopment, and physiological function in children. Children will be studied longitudinally and cross-sectionally to evaluate the effects of child/parental diet, metabolic health, and body composition on psychological-behavioral, neurologic and physiological function. B. Determine how physical activity and fitness influence psychological-behavioral outcomes, neurodevelopment, and physiological function in children. Children will be studied longitudinally and cross-sectionally to evaluate the effects of child/parental physical activity patterns, fitness, metabolic health, and body composition on psychological-behavioral, neurologic and physiological function. C. Characterize the impact of host-microbe interactions on health and development. Children will be studied longitudinally and cross-sectionally to evaluate the factors linking child/parental microbiome with metabolic health, body composition, physical activity outcomes, psychological/behavioral, neurologic and physiological functions. D. Center Development. Cooperator has the following general areas of research in the Arkansas Children’s Nutrition Center (ACNC), which address the mission area of parental/child health: Brain Development and Central Nervous System Function; Dietary Factors and Physical Activity Effects on Health, Development and Function of Organ Systems (skeleton, gastrointestinal and hepatic tissues, immune system, cardiovascular, and muscle, e.g.); and Obesity and its Effects on Cellular and Physiologic Function in mothers, infants and children.
