- A longitudinal investigation on breastfeeding planning, initiation, and duration among individuals with pre-pregnancy overweight and obesity
- We examined longitudinal relationships among breastfeeding planning, initiation, and duration, sociodemographic/clinical characteristics and pre-pregnancy BMI among individuals with pre-pregnancy BMI≥25. Pre-pregnancy BMI was not related to the likelihood of planning to breastfeed or initiating breastfeeding. However, as pre-pregnancy BMI increased, individuals were less likely to breastfeed for longer durations, even after accounting for many other sociodemographic and clinical characteristics that were related to breastfeeding duration. Future research is needed to identify how best to support individuals with higher BMIs in extending their breastfeeding duration if they desire

- Measuring food security in university students: A comparison of the USDA 10-item and six-item food security survey modules
- We examined discordant classification of food security status between the USDA 10-item and six-item Food Security Survey Modules (FSSMs) among a large sample of students at a U.S. university (N = 2653). Up to 9% of students were discordantly classified (i.e., received different food security status classifications) between the FSSMs, with higher rates of discordant classification among American Indian students, international students, Supplemental Nutrition Assistance Program participants, and students with child dependents or housing insecurity.

- Furthering development of the Eating Disorder Examination-Pregnancy Version (EDE-PV): Exploratory factor analysis and psychometric performance among a community sample of pregnant individuals with body mass index ≥ 25.
- Our research group previously adapted the Eating Disorder Examination (EDE) for use among pregnant individuals with BMI ≥ 25, and this study examined the factor structure of the EDE-Pregnancy Version (EDE-PV) in a community sample of pregnant individuals with BMI ≥ 25. An 11-item, two-factor solution produced an acceptable model fit. The subscales did not replicate those of the EDE and were interpreted as Pregnancy Eating and Weight Change Concerns and Pregnancy Shape and Weight Concerns. These subscales showed small-to-moderate, positive correlations with weight and psychosocial distress measures and differentiated between participants with and without lifetime histories of any eating disorder diagnosis. Taken together, results indicated that the EDE-PV can more reliably identify factors associated with disordered eating attitudes/behaviors among pregnant individuals with BMI ≥ 25 compared to the EDE.

- Disordered eating during pregnancy among individuals participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)
- We sought to examine the hypothesis that food assistance programs intended to reduce food insecurity, such as the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), may unintentionally contribute to eating pathology during pregnancy through a “feast-or-famine” cycle (i.e., cyclical periods of food deprivation and food access over the benefit month). In a sample of 210 low income pregnant individuals, we found that WIC participation was associated with higher scores on overall eating pathology as well as dieting and oral control subscales, but not bulimic or food preoccupation subscales, or a binge-eating item.
