Food insecurity is linked to disordered eating behaviors such as emotional eating and uncontrolled eating in minority populations, according to research presented at the 39th Annual Meeting of The Obesity Society (TOS) at ObesityWeek® 2021. The following is a summary of data from 3 poster presentations supporting this hypothesis.

Food Insecurity and Eating Pathology in Children

While more than 14 million US households experience food insecurity, research on the relationship between food insecurity and eating pathology is only just emerging, explained Jill Stadterman, MA, of Fordham University, and lead author of one of the studies with coauthors Yvette G. Karvay, MA, and Natasha L. Burke, PhD. Latinx and Black households are most affected by food security with 1.5-fold and 2-fold higher rates, respectively, than the national average.

To better understand the effects of food insecurity, researchers assessed youth aged 8 to 18 years (n=34; girls, 59%) living in the greater Bronx, New York, area prior to COVID-19. The participants were primarily Black (29%) or Latinx (23%). Participants were categorized as living with food insecurity based on parent reports over the last 12 months. Eating and weight bias symptoms were measured by self-report on the Eating Disorder Examination-Questionnaire and Weight Bias Internalization Scale.

Youth with food insecurity had higher levels of dietary restraint (an ongoing cognitive effort to restrict food intake) than their peers without food insecurity (d =0.66). It is unclear whether this finding is related to lack of access to food, desire to lose weight, and/or eating pathology, the authors noted.  

Compared with youth without food insecurity, youth with food insecurity also had a higher BMI percentile (68.7 vs 54.9) and weight bias internalization scores (d =0.32) but lower body dissatisfaction and shape/weight overvaluation scores (d =0.13 for both). Although the associations in this study had small to medium effect sizes, they were not statistically significant due to the small sample size, the study authors explained 

“In light of the COVID-19 pandemic, food insecurity rates are rising,” the researchers added. “Thus, the impact of food insecurity on weight status and eating behaviors, particularly in youth … is ever pressing.”

Uncontrolled Eating Linked to Food Insecurity in Black Women

Food insecurity was linked to high levels of uncontrolled eating and dietary restraint in Black women with overweight and obesity, according to research presented by Sarah Schmitz, MD, of Lewis Katz School of Medicine at Temple University. A higher level of dietary restraint was also seen in the earlier study on youths with food insecurity.

“It has been hypothesized that individuals who experience food insecurity alternate between periods of high food availability and food scarcity, a chronic cycle that promotes overeating and obesity when food is available and restrictive eating behaviors when food is scarce,” Dr Schmitz explained.

The findings are based on baseline data collected as part of a clinical trial that included 300 Black women with overweight or obesity in the early postpartum period. Food security was measured using the 6-item USDA Food Security Survey.

Key findings included the following:

  • 64 of the 300 participants (21%) experienced food insecurity
  • At baseline, 43% of participants in the overall group were categorized as having high emotional eating, 50% as high dietary restraint, and 45% as high uncontrolled eating
  • When compared to patients who were food secure, those with food insecurity had a 2-fold higher likelihood of uncontrolled eating and 1.9-fold higher liklihood of dietary restraint
    • These associations remained statistically significant after adjusting for age, BMI, parity, employment, and education
  • Patients with food insecurity who also reported hunger (n=21) had higher rates of high uncontrolled eating (76%) and high dietary restraint (62%)
  • Food insecurity was not associated with emotional eating

“Our findings support the hypothesis that food insecurity is linked to several disordered eating behaviors including high levels of uncontrolled eating and cognitive restraint,” Dr Schmitz concluded.

Low Socioeconomic Status Affects Healthy Eating, Physical Activity in Children

In a study involving 1415 caregivers of children attending a multidisciplinary pediatric obesity clinic, patients’ insurance status (used as a proxy for family socioeconomic status) was associated with barriers to healthy eating and physical activity (Table). The findings are based on parents’ responses to the Barriers to Healthy Eating Scale and the Barriers to Physical Activity Scale.  

Table. Barriers to Healthy Eating and Physical Activity Among Children With Low Socioeconomic Status

 FP value
Barriers to Healthy Eating  
  Child is too rushed2.777.040
  Eating healthy takes too much time2.919.033
  Unhealthy foods taste better2.986.030
Barriers to Physical Activity  
  Tired4.079.007
  Lack of time10.065.001
  School commitments4.111.007
  Family commitments2.885.035
  Other priorities3.802.010

A majority of the children (65%) identified as Black and 21% identified as White. The mean age of the children was 12 years.

“For children treated for obesity, insurance status and other socioeconomic issues are important to consider,” said Crystal Lim, PhD, ABPP, and Cameronne Dodd, MS, of University of Mississippi Medical Center. The study results will be used to develop interventions that are applicable and feasible for families with low socioeconomic status, the researchers said.

All of the study authors called for further investigation of the impact of food insecurity and socioeconomic status on weight status, eating pathology, and eating disorders.
