Abstract P289: Understanding Perceived Risk of Type 2 Diabetes in Healthy Middle-aged Adults
Introduction: For type 2 diabetes (T2D) prevention programs to successfully reach their intended targets, high-risk individuals must first be aware that they are at high risk. Greater understanding of factors associated with perceived risk might inform the development of more effective risk communication and prevention efforts. We aimed to determine the perceived risk of T2D in a population-based sample of healthy middle-aged adults and examine its relation to modelled risk, clinical risk factors, and psychological factors theorised to be antecedents of behaviour change.
Methods: An exploratory, cross-sectional analysis of perceived lifetime risk of T2D was conducted using baseline data collected from 569 participants in the Diabetes Risk Communication Trial (Cambridgeshire, UK). T2D risk factors were measured during a health assessment and the Framingham Offspring Diabetes Risk Score was used to model risk. Questionnaires assessed various psychological factors. Multivariable regression analyses were used to determine associations with perceived risk.
Results: Table 1 shows that participants (mean (SD) age = 48.8 (7.3) years; n (%) male = 265 (47.5); mean (SD) BMI = 26.1 (4.23) kg/m2) with a higher lifetime perceived risk (mean (SD) = 34.8% (24.05%)) were at higher risk according to the Framingham Offspring Diabetes Risk Score (mean (SD) = 11.7% (19.0%)) (p < 0.001). Higher perceived risk was associated with higher body fat percentage, lower self-rated health, higher diabetes-related worry, and lower self-efficacy for adhering to governmental recommendations for physical activity (all p < 0.001).
Conclusions: Overestimation of T2D risk is common. Higher perceived risk is associated with higher risk of developing the disease, and decreased likelihood of engagement in risk-reducing health behaviours. Risk communication interventions should target high-risk individuals with messages about the effectiveness of prevention strategies and address ability to engage in risk-reducing health behaviours.
