Comparing Food Insecurity between Veterans and non-Veterans


BACKGROUND:
Poor and inconsistent access to healthful nutrition is associated with a multitude of adverse health outcomes including cardiovascular disease, diabetes, mental illness, and poor overall health. Given that food insecurity affects at least 14% of U.S. households, the ensuing disease burden is significant. Recent studies have identified increasing age as a risk factor for food insecurity. During the next decade, there will be a 12% growth in the number of Veterans using VA healthcare that are over age 65, yet our understanding of the prevalence of food insecurity among older Veterans and how it compares to older non-Veterans is limited. Therefore, this study examined the prevalence of food insecurity in an older male population. Investigators used data from the 2012 Health and Retirement Study (HRS) and the 2013 HRS Health Care and Nutrition Mail Survey of 2,560 male participants (1,254 Veterans) to estimate prevalence and identify any significant predictors of food insecurity.

FINDINGS:

  • There was a significantly lower prevalence of food insecurity among male Veterans compared to non-Veterans (6% vs. 12%, respectively). Nevertheless, several factors predisposed male Veterans to a higher risk for being food insecure.
  • Younger Veterans (aged 50-64) were more likely to be food insecure and had nearly three times the prevalence of food insecurity compared to Veterans aged 65+ (12% vs. 4%, respectively).
  • Overall, having a psychiatric diagnosis, self-reporting symptoms consistent with clinical depression, smoking, and experiencing any difficulty with activities of daily living (ADLs) were all significantly associated with increased odds of being food insecure, even after adjustment for demographics, medical comorbidities, and economic status.

IMPLICATIONS:

  • Veterans aged 50-64 are not yet eligible for Social Security benefits, and particular attention should be paid to their psychological and functional status.This group in particular should be screened for food insecurity.
  • While older Veterans (65+) are less likely than their younger counterparts to be food insecure, depression was highly prevalent, and was a significant risk factor for food insecurity. Special attention should be paid to the atypical symptoms of depression that can manifest in the elderly.

LIMITATIONS:

  • As a cross-sectional study of survey responses, findings cannot be used to establish causality or to surmise if or how food security status may change over time.
  • Because food security was assessed via self-report, investigators cannot exclude the possibility that recall and social desirability biases may have influenced prevalence rates.
  • The HRS only evaluates participants with permanent addresses, thus precluding the assessment of thousands of transient or homeless older Veterans.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
