Perceptions about eating experiences of low-literate older adults with heart disease: a qualitative study.

Aims. To explore perceptions of low-literate older adults with heart disease about their eating experiences. Background. Heart disease has been closely linked with nutrition, and nutritional status is poor in patients with limited education, but no studies have explored the eating experiences of low-literate adults with heart disease. Design. Qualitative descriptive study. Methods. Data were collected in tape-recorded semi-structured interviews from March - June 2012. A convenience sample of 13 low-literate older adults with heart disease was recruited from a cardiovascular ward of a medical centre in northern Taiwan. Participants were recruited until findings reached saturation and data were analysed using qualitative content analysis. Findings. Analysis of participants' interview data on eating experiences identified three main categories: (1) eating-related hardships because of low literacy; (2) eating adjustments due to low literacy; and (3) misinformation about dietary modifications for heart disease. Conclusion. Because of their low literacy, these older adults had difficult life experiences, gained inappropriate or inadequate eating information and held a passive, fatalistic perspective about eating with heart disease. Healthcare practitioners caring for this population need to appreciate their unique eating challenges and respect their eating customs. Nurses could play a greater role in educating and supporting low-literate older adults in selecting appropriate foods and preparing meals. Strategies to help this population learn to select, prepare and cook their food should be easy and practical, using specific symbols, concrete signs and simple labels.
