Progress 10/01/07 to 09/30/11
Outputs
OUTPUTS: Combined data from the BLS consumer expenditure survey and the American Time Use Survey; Created a data set using the National Health and Nutrition Examination Survey; Matched data sets using propensity score matching techniques; Analyzed subcategories of sample to predict the probability of overweight and respondent BMI; Presented results at the International Time Use conference at the University of Maryland. PARTICIPANTS: Erin Buckwalter, Graduate Student Amanda Goldstein, Research Associate TARGET AUDIENCES: Academics General informed lay audiences peers PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Several time use patterns are evident from the analysis; individuals who can be classified as active are the smallest group. Several eating patterns are evident from the data, including an away from home group and at home group. Eating and time use patterns impact BMI differently for healthy and overweight individuals. Spending more time in meal preparation is associated with a lower BMI in already overweight people. Secondary eating is associated with a lower probability of overweight, but a higher BMI if an individual is already overweight.

Progress 10/01/09 to 09/30/10
Outputs
OUTPUTS: The purpose of this project is to examine how time use patterns are related to obesity. Using the American Time Use Survey combined withe its Eating and Health Module, we have begun to identify time pattern clusters for separate demographic groups identified, in part, using the Dietary Guidelines for Americans groupings. Different demographic groups each have a variety of time use pattern clusters. The only time use cluster that is related to decreases in obesity is the pattern that includes more physical activity than the other pattersn. However, there are normal and overweight individuals in every time use cluster. The results thus far have been presented at national and international conferences, and published in the literature. Next steps for this project include linking eating behavior data with time use pattern data. PARTICIPANTS: Jane Kolodinsky, Ph.D. is professor and Chair of the Department of Community Development and Applied Economics at the University of Vermont. She also is Director of the Center for Rural Studies and the affiliate Food Systems Research Collaborative. Amanda Goldstein, M.S., is a research associate in the Department of Community Development and Applied Economics and the Center for Rural Studies at the University of Vermont. TARGET AUDIENCES: Results of this study can benefit academics interested in moving toward transdisciplinary initiatives in obesity research and more lay audiences who need concrete advice on behaviors that can help decrease obesity. PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
For single, female headed households ages 31-50, the only cluster significantly related to being overweight is the cluster characterized by an "active lifestyle" with fewer sedentary time use, including screen time and non-active leisure. In addition, we find that time spent in primary eating decreases the probability of being overweight in a normal weight sample, but increases the probabiility of being overweight in an overweight sample. We also find that time spent cooking meals at home decreases the probability of being overweight in an overweight sample.

Progress 10/01/08 to 09/30/09
Outputs
OUTPUTS: This project examines the production of health capital as measured by a healthy weight in a sample of single headed households with children. Using the theory of health capital, a household production model and a combination of the American Time Use Survey (ATUS), Eating and Health Module of the ATUS, Current Population Survey (CPS), and Consumer Expenditure Survey (CEX) data, time and purchased inputs used to produce meals and energy expenditure (activity and exercise) will be determined and their impact on obesity estimated. The mediating effects of productivity and preference shifters, the price of time, and non wage income sources, including food assistance will be investigated. Estimation will control for sample selection bias related to the participation in food assistance programs and impute purchased inputs into meal production using CEX data. The study will increase our understanding of how trade-offs in time and purchased input use in low income households affect the production of health capital as measured by a healthy weight. PARTICIPANTS: Jane Kolodinsky, P.I. Graduate Students, Erin Roche, Amanda Goldstein University Transportation Center Department of Nutrition and Food Science TARGET AUDIENCES: Academic audiences are interested in the methods and estimates. Informed lay audiences are interested in the practical applications of the findings. PROJECT MODIFICATIONS: We are investigating adding the NHANES to the analysis.
Impacts
The Consumer Expenditure Survey (CEX) was aggregated by household composition and income level so that mean expenditures on food categories could be imputed into the American Time Use Survey (ATUS). Information from the Eating and Health Module of the ATUS was also merged into the ATUS dataset so that body mass index (BMI) could serve as a proxy for health capital and its dependence on time use and purchased inputs estimated. Methodological hurdles included reorganizing the CEX food categories to fit within traditional nutritional guidelines and matching data from the CEX to ATUS respondents. We are currently moving on to include NHANES data and using propensity matching techniques to combine data sets.
