Diabetes-related nutrition knowledge and dietary adherence in patients with Type 2 diabetes mellitus: A mixed-methods exploratory study

Abstract

Aim: The aim of the study is to gain insights into the relationship between diabetes-related nutrition knowledge (DRNK) and diet quality in Singapore. Methods: Forty-two participants were recruited from a tertiary hospital. DRNK and diet quality were ascertained with the DRNK questionnaire and Alternate Healthy Eating Index 2010, respectively. Twenty-one semi-structured interviews of perceived barriers and enablers to adherence to dietary guidelines were audio recorded, transcribed and analysed. Results: Participants had a poor mean percentage DRNK score of 39.7% (±17.7) and diet quality of 54.2% (±9.4). Pearson’s correlation tests revealed no correlation between DRNK and diet quality ( r –0.29; p=0.065) but suggest a moderate positive correlation between DRNK and psychosocial self-efficacy ( r 0.41; p=0.008). Thematic analysis revealed six barriers (obesogenic environment; lack of time; conflict between advice and personal values; stress from external sources; lack of personal motivation; gaps in DRNK) and four enablers (personal motivation to improve condition; fear of T2DM complications; sufficient DRNK; presence of social support) to adherence to dietary guidelines. Conclusion: DRNK may not correlate with adherence to dietary guidelines; multiple mediating factors are identified when translating DRNK to practice.

Study from Singapore indicates that lack of social support from families and friends of persons with diabetes were strong barriers to adherence in dietary recommendations [31] which is consistent with our results.…”

Adherence to Dietary Guidelines in Adults by Diabetes Status: Results From the 2012 Mexican National Health and Nutrition Survey
