Abstract
Purpose To examine daily fruit and vegetable (FV) intake frequency by household food security status (high food security, marginal food security, low food security, and very low food security), and scores on three hunger-coping behavior scales (i.e., “rationing food supplies”, “financial strategies”, and “trade-off strategies”), and one physiological hunger symptoms scale among a very low-income population in the Midwestern United States.
Methods Adult participants (aged 19 and older and caregivers to at least one child aged 0-18) were recruited from public libraries, food pantries, and other community locations to participate in a cross-sectional self-administered survey (n = 306). The primary outcome variable was daily FV intake frequency, measured from five items from the 16-item NYPANS dietary screener (fruit, green salad, carrots, other vegetables, and non-fried potatoes). These items were converted into daily frequencies and then summed. Daily FV intake frequency was also log transformed to meet statistical model assumptions. The main independent variables in this study were household food security (measured using the 6-item USDA Household Food Security Survey Module), scores on three 5-item hunger-coping behavior scales (max scores = 5), and one 5-item physiological hunger symptoms scale (max scores = 5). Potential sociodemographic and household characteristics (e.g., sex, age, race/ethnicity, education, income, marital status, food assistance, income assistance, food pantry use, household child to adult ratio, and automobile access) were assessed as potential covariates. Generalized linear models were used to assess the relationship between independent variables and daily FV intake frequency.
Results 278 participants provided complete data for the outcome variable and were included in the sample. The sample was 73% female, 45% African American, 14% Hispanic, and 28% Caucasian. A majority of participants (60%) reported annual household incomes under $15,000. A high proportion of participants (42%) had very lowfood security, as compared to the national average of 6%. Participants reported consuming FV 2.40 times per day (SD=1.76) on average. Compared the high food secure group (In adjusted models), being in the “very low” food security group was associated with a 26% decrease, on average, in daily FV intake frequency (exp(β)=0.74, 95%CI=0.61-0.88, p
Conclusions Compared to the high food secure group, those in the “very low” food secure group reported a significantly lower mean daily FV intake frequency, but not those in the “low” food secure group. This emphasizes the need to examine the “low” and “very low” food secure groups separately when studying factors associated with diet. Engaging in hunger-coping behaviors and experiencing physiological hunger symptoms was associated with decreased daily FV intake frequency. It is not clear if the hunger coping-behaviors themselves directly lead to decreased daily FV intake frequency, or if they were a marker for food insecurity and associated economic distress. These constructs and relationships should be examined in future studies. Programs and policies, which seek to promote fruit and vegetable intake among low-income populations, should target the “very low” food secure as the most at-risk for low intake. Also, researchers and community organizations working with food insecure groups could potentially measure hunger-coping behaviors and hunger symptoms in a complementary fashion to traditional measures of food insecurity to gain more contextual information about the experiences of this population.
Key Take Away Points
- Assessing other factors that may be related to food security, such as hunger-coping behaviors and physiological hunger symptoms, may help to provide a more comprehensive look at a household’s overall food sufficiency.
- Decreased daily fruit and vegetable frequency is related to higher levels of food insecurity, engaging in more hunger-coping behaviors, and experiencing more physiological hunger symptoms.
- Intervention, programs and policies focusing on healthful diets may consider targeting households in the very low food secure category and in particular, children living in these households.

Ms. Fricke has experience researching childhood obesity, hunger and food security, local food systems, local and statewide needs for increasing Supplemental Nutrition Assistance Program (SNAP) participation, as well as relationships between dietary intake, food security, and food sufficiency. At GSCN, Ms. Fricke primarily oversees a multi-year collaborative, community-based project to alleviate childhood hunger in the Omaha, Nebraska metro area. Eric Calloway, Ph.D., R.D. is a postdoctoral fellow at the Gretchen Swanson Center for Nutrition (GSCN). Dr. Calloway research interests include food purchasing, hunger, food insecurity, and obesity prevention among low-income populations. Previous to GSCN, he worked as a project specialist for the Center for Nutrition Policy and Promotion developing evidence reviews for the Scientific Report of the 2015 Dietary Guidelines Advisory Committee, including authoring evidence reviews relating to dietary patterns, food insecurity, and cancer risk. Teresa Smith, Ph.D., M.S. is a postdoctoral fellow at GSCN. Dr. Smith’s research expertise lies in the environmental, social and individual determinants of dietary behaviors as they relate to obesity prevention and cancer risk. This includes, but is not limited to, cultural and familial influences on individual dietary behaviors, healthy foods access and availability, issues of food insecurity and dietary measurement and analysis. She is also an affiliate scholar with the Montana State University Food and Health Lab. Courtney Pinard, Ph.D., MHK is a Research Scientist at the GSCN and also has an appointment as Adjunct Assistant Professor in the Department of Health Promotion, Social and Behavioral Health at in the College of Public Health at the University of Nebraska Medical Center (UNMC). Dr. Pinard has led and collaborated on studies in areas including obesity prevention, local food systems and health, and food insecurity, using range of approaches such as secondary and primary data analysis, qualitative methodology, and intervention at individual, community and policy levels. Amy Yaroch, Ph.D. is the Executive Director at the Gretchen Swanson Center for Nutrition and also has an appointment as Adjunct Professor in the Department of Health Promotion, Social and Behavioral Health at in the College of Public Health at UNMC. Before joining the Center six years ago, Dr. Yaroch was a Program Director and Behavioral Scientist in the Health Promotion Research Branch at the National Cancer Institute, where she oversaw research efforts in the areas of nutrition, obesity prevention, and behavioral sun safety/skin cancer prevention.
