Diet self-management and readiness to change in underserved adults with type 2 diabetes

Dietary assessment in diabetes may be enhanced by considering patient-centered perspectives and barriers to change within IDF guidelines. Consideration of readiness to change (RTC) diet in underserved samples may guide future interventions in high risk populations. This study assesses the utility of a rapid assessment of RTC diet in a medically underserved sample.

Participants were 253 Black (43.7%) and White (55.1%) American adults with type 2 diabetes [M age=57.93 (11.52); 60.5% female; 19% below the US poverty threshold]. Participants were recruited at medical clinics and completed validated self-report measures assessing diabetes knowledge, self-efficacy and dietary behaviors and barriers by RTC.

Stage-based comparisons identified significant differences in diabetes and dietary domains: participants in the Action stage endorsed fewer behavioral dietary barriers (p<.001), more frequent dietary problem-solving (p<.001), and greater diabetes self-efficacy (p<.001) than participants in the Contemplation and Preparation stages. Women were more likely to be in the Preparation stage and beyond (p<.05).

Findings highlight the clinical utility of a brief measure of RTC in understanding patient perspectives toward dietary behaviors in a medically underserved sample. The impact of gender on RTC diet warrants further exploration.
