RESUMO
AIM: To explore the beliefs and perceptions of type 2 diabetic patients in La Réunion where the disease is highly prevalent (17.5% among 30-69 yr old subjects) with a strong link to the metabolic syndrome and nutritional habits. METHODS: Two sets of data were analysed. An 80-item questionnaire explored the perceptions of causal factors, knowledge of complications and therapeutic issues in 331 known diabetic patients included in the REDIA study. The data were completed by semi-structured interviews of 40 diabetic patients in a hospital setting. RESULTS: Perceived causal factors of diabetes are mainly sugar excess, heredity and stress or life events. Weight excess and lack of physical activity are virtually never mentioned as causes. Diabetes is predominantly perceived as potentially acute, with risk of coma and death. Its chronic and progressive nature is not appreciated, and chronic complications are not well understood, especially in poorly educated people. Only 33% of males and 42% of females are willing to change their nutritional habits and the role of fats is largely underestimated (30.2%) although 90% consider physical activity as an effective course of action. Most patients are tardy in the way that they adopt medical recommendations and treatment in the course of the disease. CONCLUSION: These results highlight the discrepancy between medical knowledge and patients' perceptions, especially concerning etiological issues and complications. Lifestyle and therapeutic recommendations are not well understood. Educational activities need to consider the knowledge issues and understanding by patients early in the course of chronic diseases like diabetes.
