# Dietary Risk Among Older Adults: Examining the Role of Food Insecurity and Social Isolation

## TL;DR

This study explores how food insecurity and social isolation affect dietary risk in older adults, finding that systemic factors may play a bigger role than previously thought.

## Contribution

The study provides new insights into the limited role of food insecurity and social isolation in dietary risk among older adults.

## Key findings

- 93% of the sample was at risk for low dietary quality using a DST threshold of ≤60.
- Food insecurity was 52%, but both food-insecure and food-secure individuals had high dietary risk (48% and 45%).
- No significant association was found between social isolation and dietary quality.

## Abstract

As the aging U.S. population grows, so do healthcare challenges, particularly in nutrition and dietary quality. Older adults face a higher risk of malnutrition, affecting health and quality of life. Dietary intake is influenced by health, social environments, and food access, but their combined impact remains unclear among vulnerable populations. While food security is recognized as crucial for adequate nutrition, the role of social and environmental factors in dietary quality is less understood. The Deliver-EE trials aim to explore these relationships. The purpose of our investigation is to assess the relationships between social isolation, food insecurity, and dietary risk, contributing to a deeper understanding of nutrition among older adults. With a Dietary Screening Tool (DST) threshold of ≤ 60, 93% of the sample was categorized as at risk for low dietary quality. Food insecurity in the sample was 52%, yet a high proportion of both food-insecure and food-secure individuals were at risk for low dietary quality (48% and 45% respectively). No significant association was found between social isolation and DST scores. Dietary risk does not seem to be associated with food insecurity or social isolation. These findings suggest that systemic factors, rather than ability to afford food and social connectivity, drive dietary risk. Future research should examine nutritional gaps in food assistance programs and structural determinants of dietary quality in vulnerable populations.
