This paper investigates one explanation for the consistent observation of a strong, negative correlation in the United States between income and obesity among women, but not men. We argue that a key factor is the gendered expectation that mothers are responsible for feeding their children. When income is limited and households face food shortages, we predict that an enactment of these gendered norms places mothers at greater risk for obesity relative to child-free women and all men. We adopt an indirect approach to study these complex dynamics using data on men and women of childrearing age and who are household heads or partners in the 1999e2003 waves of the Panel Study of Income Dynamics (PSID). We find support for our prediction: Food insecure mothers are more likely than child-free men and women and food insecure fathers to be overweight or obese and to gain more weight over four years. The risks are greater for single mothers relative to mothers in married or cohabiting relationships. Supplemental models demonstrate that this pattern cannot be attributed topost-pregnancy biological changes thatpredispose mothers toweight gain or an evolutionary bias toward biological children. Further, results are unchanged with the inclusion of physical activity, smoking, drinking, receipt of food stamps, or Women, Infants and Children (WIC) nutritional program participation. Obesity, thus, offers a physical expression of the vulnerabilities that arise from the intersection of gendered childcare expectations and poverty.

Scholars argue that it takes money to maintain a healthy weight in America’s obesogenic environment (Poston & Foreyt, 1999) because healthy food is relatively expensive and calorie-dense, nutrient-poor food is cheap (Drewnowski & Specter, 2004). Although weight is a function of both caloric intake and expendi- ture, materialist arguments focus on the costs of food and predict greater caloric intake and consequent body fat among low versus high income people (Glass & McAtee, 2006). In the U.S., there is a strong, negative correlation between income and the likelihood of being overweight or obese, but only among women; this is not observed among men (for reviews, see McLaren, 2007; Sobal & Stunkard, 1989). This sex difference is puzzling, particularly to scholars who look beyond individual explanations to consider the role of shared environments for health because the majority of men and women live together (Casper & Bianchi, 2002) and share socioeconomic resources and weight-related behaviors (French, Story, & Jeffery, 2001; Mitchell et al., 2003). Given these common- alities, one would expect greater similarity between the sexes.

We hypothesize that the key distinction is not between all women and all men, but between mothers and non-mothers. We

argue that the confluence of two factors e the experience of food insecurity and the gendered nature of childcare e intersect and contribute to the observed sex differences in the association of income and body weight. Food insecurity is highly correlated with poverty (Sarlio-Lähteenkorva & Lahelma, 2001) and occurs when a household faces budgetary constraints that limit the quantity or quality of food they can purchase (Wunderlich & Norwood, 2006). Yet food insecurity is a “managed process” (Radimer, 1990), meaning that families strategize and diligently work to avoid hunger. That responsibility, however, falls more heavily on women given traditional discourses about family life and “women’s work” that place greater expectations on women for feeding and nurturing their family, especially when children are present (DeVault, 1991). Given that food insecurity is correlated with poor dietary behavior and obesity (for a review, see Institute of Medicine, 2011), we assert that food insecurity mediates the association between income and weight, but that the management of food insecurity intersects with gender to create differential risks for obesity between mothers and non-mothers.

To investigate these dynamics, we study men and women of childrearing ages (i.e., 18e55) who are heads or partners of U.S. households in the 1999, 2001 and 2003 waves of the Panel Study of Income Dynamics (PSID). We test whether the association between

household food insecurity and the likelihood of being overweight or obese differs across groups defined by sex and parenthood in cross-sectional models of weight status and longitudinal models of weight change. We also examine how partner co-residence further moderates these processes due to the gendered norms about parental custody (Coltrane & Adams, 2003) and the greater prev- alence of food insecurity among single parents (Rose, Gundersen, & Oliveira, 1998).
