Abstract
Older adults have low whole grain (WG) intake. This qualitative study used the Theory of Planned Behavior (TPB) to identify low-income older adults’ WG beliefs. A convenience sample of 25 low-income adults 60 years and older were interviewed using questions developed based on TPB constructs: behavioral, normative, and control beliefs. Interviews were audio-recorded, transcribed verbatim, cross-checked for consistency, and analyzed using content analysis. Study results revealed that regarding behavioral beliefs, health benefits, taste, and nutrition were WG advantages and sensory qualities, higher cost, and longer cooking time were disadvantages. Regarding normative beliefs, healthcare professionals and family members approved WG intake and those less informed about WGs disapproved. Regarding control beliefs, availability/accessibility, knowledge of WG benefits, and WG cooking skills facilitated WG intake and age-related changes, WG cost, decreased motivation to cook, and low knowledge (label reading) were barriers. Results provide insights for developing programs to increase older adults’ WG intake.
