Obesity research consistently does not observe a strong, negative correlation in the United States between income and obesity among men, but does among women. This study examines this negative correlation, positing that a significant factor is the gendered role of mother. The study characterizes the differences in weight related to food insecurity as differences between mothers and non-mothers, not men and women.
Data from the Panel Study of Income Dynamics (PSID) was used to examine the 1999–2003 waves. The final sample included 7,931 men and women of childrearing age who were household heads or partners.
This study demonstrates the connection between overweight and obesity and food insecurity. The study does not include immigrant populations. Future research should expand the portion of the population studied.
