Abstract [en]

The world is facing major challenges regarding life style related chronic diseases. Improved ultrasound techniques enable assessment of risk for cardiovascular diseases (CVD) by measurement of atherosclerosis while still asymptomatic. Evidence for the potential of pictorial-based health risk communication to motivate life style modifications is promising but weak. More research, especially longitudinal intervention studies, is requested. In the literature, relevant health psychological constructs such as risk perception and response efficacy are often neglected, even though they are known to mediate and moderate behavioural changes. VIPVIZA is a population-based randomized controlled trial that aims at optimizing CVD prevention by assessing the impact of visualization of silent atherosclerosis. 690 participants, the majority 60 years old, were included in this study. The primary purpose was to investigate whether cognitive and emotional factors moderate behavioural and biomedical health outcomes of pictorial-based health risk communication. Cognitive factors were risk perception, response efficacy, motivation and assessment of life style modification. Emotional factors included being positively surprised, relieved/calmed, insecure, afraid and shocked. Behavioural and biomedical health outcomes included fruit and vegetable consumption, physical activity, smoking, alcohol consumption, body weight, blood sugar, LDL-cholesterol and blood pressure. ANCOVA analyses showed a pattern of small but positive associations between assessments of cognitive factors and health outcomes, where participants had better health outcomes if the intervention had affected their risk perception, response efficacy, etc. Assessment of cognitive factors, in turn, were associated with emotional reactions, but not with ultrasound results.
