BACKGROUND: The effects of the home environment on child health behaviors related to obesity are unclear. PURPOSE: To examine the role of the home physical activity (PA) and food environment on corresponding outcomes in young children, and assess maternal education/work status as a moderator. METHODS: Overweight or obese mothers reported on the home PA and food environment (accessibility, role modeling and parental policies). Outcomes included child moderate-vigorous PA (MVPA) and sedentary time derived from accelerometer data and two dietary factors ('junk' and healthy food intake scores) based on factor analysis of mother-reported food intake. Linear regression models assessed the net effect (controlling for child demographics, study arm, supplemental time point, maternal education/work status, child body mass index and accelerometer wear time (for PA outcomes)) of the home environment on the outcomes and moderation by maternal education/work status. Data were collected in North Carolina from 2007 to 2011. RESULTS: Parental policies supporting PA increased MVPA time, and limiting access to unhealthy foods increased the healthy food intake score. Role modeling of healthy eating behaviors increased the healthy food intake score among children of mothers with no college education. Among children of mothers with no college education and not working, limiting access to unhealthy foods and role modeling reduced 'junk' food intake scores whereas parental policies supporting family meals increased 'junk' food intake scores. CONCLUSIONS: To promote MVPA, parental policies supporting child PA are warranted. Limited access to unhealthy foods and role modeling of healthy eating may improve the quality of the child's food intake.

Unhealthy lifestyle factors, such as tobacco use, poor dietary intake, lack of physical activity, and high body mass index are the leading causes of cancer and chronic disease. The prevention of such diseases will be advanced through a more thorough understanding of the complex determinants of these lifestyle factors and the development of novel interventions that help change individual behavior for the better. Dr. Fuemmeler’s program of research takes a lifespan approach toward understand

Our laboratory studies individuals who have difficulty detecting, interpreting, and/or using signals from their body and using this information to guide adaptive behavior. We explore how disruptions in these capacities contribute to psychosomatic disorders such as functional abdominal pain or anorexia nervosa and how the adaptive development of these capacities helps individuals to know themselves, trust themselves, and flourish. Our primary populations of study are individuals
