Nutrigenomics Hypothesis: Examining the Association Between Food Stamp Program Participation and Bodyweight Among Low-Income Women Journal of Family and Economic Issues 32,3 (September 2011): 508-520.

This paper examines the association between food stamp program participation and bodyweight among 1,723 eligible women who were respondents of the National Longitudinal Survey of Youth 1979 Cohort. The study sample was stratified by race/ethnicity and two time periods, i.e., 1987–1996, 1998–2002, to allow for genetic and cultural differences and a potential structural break due to the 1996 welfare reform. We test a hypothesis based on the nutrigenomic literature suggesting that genetic heterogeneities result in varying effects of nutrition or food-borne components on metabolism. Differences in socioeconomic characteristics between participants and eligible non-participants were identified. We find a positive association between food stamp program participation and bodyweight among Hispanic women, particularly those of foreign-born. |

Does Early School Entry Prevent Obesity Among Adolescent Girls? Journal of Adolescent Health 48,6 (June 2011): 644-646. Also: http://www.jahonline.org/article/S1054-139X%2810%2900478-7/abstract Cohort(s): NLSY97 Publisher: Elsevier Keyword(s): Body Mass Index (BMI); Gender Differences; Height; Nutritional Status/Nutrition/Consumption Behaviors; Physical Activity (see also Exercise); School Entry/Readiness; Self-Reporting; Weight Purpose: To examine the relationship between early school entry and body weight status among adolescent girls. Methods: Using nationally representative data from the 1997 cohort of the National Longitudinal Survey of Youth, we exploited state-specific first-grade entrance policy as a quasi-experimental research design to examine the effect of early school entry on the body weight status of adolescent girls. Fixed-effects models were used to compare the body mass index (BMI), BMI z-score, and likelihood of overweight and obesity between teenage girls born before school cut-off dates and those born after, while controlling for age, race/ethnicity, maternal education status, and maternal body weight status Results: Late starters had higher BMIs and a higher prevalence of overweight and obesity and the results were found to be consistent across age groups. Among girls whose birthdays were within 1 month of the cut-off dates, the coefficient of late starting was significantly positive (Beta=.311; p=.02), indicating that it might be correlated with weight gain in adolescence. Conclusions: Early admission to a school environment might have a long-term protective effect in terms of adolescent girls’ propensity to obesity. Future studies are needed to examine the effect of early school entry on the eating behavior and physical activities of adolescent girls. |

Prices of Unhealthy Foods, Food Stamp Program Participation, and Body Weight Status among U.S. Low-Income Women Journal of Family and Economic Issues 32,2 (June 2011): 245-56. Also: http://www.springerlink.com/content/9t80867m29252804/ Cohort(s): NLSY79 Publisher: Springer Keyword(s): Body Mass Index (BMI); Food Stamps (see Supplemental Nutrition Assistance Program); Income Level; Nutritional Status/Nutrition/Consumption Behaviors; Obesity; Program Participation/Evaluation; Socioeconomic Status (SES); Weight; Women Permission to reprint the abstract has not been received from the publisher. This paper examines the interactive effect between the price of unhealthy foods and Food Stamp Program participation on body weight status among low-income women in the United States. We merged the panel data of the National Longitudinal Survey of Youth 1979 cohort in 1985-2002 and the Cost of Living Index data compiled by the American Chamber of Commerce Researchers Association by using geographic identifiers. Using the merged data, we used panel econometric models to examine the impact of unhealthy food prices on the food stamp-eligible U.S. population. Our results indicate that higher prices for unhealthy food can partially offset the positive association between Food Stamp Program participation and bodyweight among low-income women. |
