Diet quality and exercise in older veterans with PTSD: a pilot study

Abstract

Lay Summary Older veterans with posttraumatic stress disorder (PTSD) are at risk for several physical health conditions that reduce their quality of life. Physical activity and healthy eating are important behaviors for promoting good health and physical function in later life. The purpose of this study was to examine the diet quality of older veterans with PTSD and explore whether a program designed to increase exercise also improved diet. Diet quality was measured with a self-report survey, the Dietary Screener Questionnaire (DSQ), which measures daily intake of fiber, calcium, added sugar, whole grain, dairy, and fruits/vegetables/legumes. Study participants were 54 military veterans age 60 years and older with PTSD who participated in a randomized controlled pilot trial comparing 12 weeks of supervised exercise to wait-list usual care. The DSQ was administered at baseline and 12 weeks post intervention. Results show that older veterans with PTSD have overall poor diet quality that included consuming too much added sugar and not enough whole grains, fruits/vegetables/legumes, fiber, calcium, and dairy. Participation in the supervised exercise did not lead to simultaneous diet quality changes over 12 weeks. This study shows that diet quality is poor in older veterans with PTSD and future programs are needed to target this health behavior.
