Abstract
Objectives
Food insecurity affects 11% of the United States (U.S.) population and leads to decrements in health and quality of life. Aside from grey literature, little is known about food insecurity among military personnel. The purpose of this study was to identify prevalence, gender discrepancies, and characteristics associated with food insecurity among U.S. Army soldiers. Investigators hypothesized that female soldiers who experience food insecurity will have higher body mass indices (BMI) than male soldiers, and that earning less income, being un-partnered, and having dependents while unmarried would be associated with food insecurity, irrespective of gender.
Methods
In this cross-sectional study, data were collected from 218 soldiers using the U.S. Household Food Security Survey Module: Six Item Short Form and a demographics questionnaire. Independent samples T-test and Chi square determined differences between samples. Two-way analysis of variance assessed interaction and main effects of food insecurity and gender on BMI. Logistic regressions determined likelihood of food insecurity based on paygrade, gender, marital status, number of dependents, and barracks residence.
Results
Over 22% of the sampled population was food insecure. When compared to food secure individuals, food insecure soldiers were younger (23.6 vs. 26.6 years) and had fewer dependents (0.70 vs. 1.16). Food insecure women had higher BMIs (25.3 vs. 23.5 kg/m2). Barracks residency was associated with food insecurity (χ2 = 7.290, P = 0.007). Main effects were significant for gender on BMI (P = 0.001), but interaction effects for food insecurity on BMI were not (P = 0.16). Soldiers with the rank of Private (OR = 5.510, P = 0.029) and Specialist (OR = 5.750, P = 0.032) had increased likelihood of food insecurity compared to officers.
Conclusions
Female soldiers and barracks residents may be most affected by food insecurity, which may have health implications that could affect career advancement and retention. The potential impact of food insecurity on military readiness and resiliency indicates the phenomenon may pose a risk to national security.
