Abstract [en]

Introduction: Cardiovascular disease (CVD) is a major cause of death in the world. Risk behaviours increases prevalence of CVD and evidence indicate that around 80% of CVDs could be prevented if unhealthy behaviours were eliminated. Increased intima media thickness (IMT) and arterial plaque are signs of atherosclerosis, the underlying cause of CVD, and important predictors of CVD which can be evaluated with ultrasound examination. This thesis investigates whether emotions evoked by pictorial information from ultrasonic examination of the carotid arteries in asymptomatic individuals, have any association with information acquisition about CVD or changes in risk behaviours.

Method: A subgroup of participants from the VIPVIZA randomized controlled trial intervention population answered a set of questions about emotional responses to the pictorial ultrasound report given to them after carotid ultrasound examination at baseline. They also answered open questions about behavioural changes and attainment of information about CVD during the first year of follow up. Answers to the open questions were categorized using quantitative content analysis and used in quantitative analyses. The chi-square test was used on the categorical variables and logistic regression was used to investigate associations between emotional reactions and inclination to find additional information about CVD or changes in behaviours.

Results: Partly or completely agreeing with feeling worried or unsure compared to completely disagreeing increased the odds of changing behaviour (OR 2,85 95% CI 1,18- 6,86; OR 3,80, 95% CI 1,59- 9,11), partly disagreeing with feeling unsure also increased the odds of behavioural change (OR 7,95, 95% CI 1,62- 38,99). Partly or completely agreeing with feeling positively surprised decreased the odds of making behavioural changes (OR 0,37, 95% CI 0,16- 0,86). Agreeing partly or completely with feeling shocked increased the odds of looking for information (OR 2,75, 95% CI 1,14- 6,64) and agreeing partly or completely with feeling unsure increased the odds of looking for information (OR of 3,11, 95% CI 1,21- 7,98) compared to completely disagreeing.

Conclusion: The results suggest that emotions play a part in promoting behavioural change and attainment of information after the intervention, but the mechanisms through which emotions act in the chain leading to behavioural change are not known. This was a small study which limits the possibility to draw clear conclusions and more studies using other methodology and additional aspects of behaviour change are needed to find the best ways to promote healthy lifestyles.
