- Purpose: Previously reported associations of protein-rich foods with stroke subtypes have prompted interest in the assessment of individual amino acids. We examined the associations of dietary amino acids with risks of ischaemic and haemorrhagic stroke in the EPIC study.Methods: We analysed data from 356,142 participants from seven European countries. Dietary intakes of 19 individual amino acids were assessed using validated country-specific dietary questionnaires, calibrated using additional 24-h dietary recalls. Multivariable-adjusted Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of ischaemic and haemorrhagic stroke in relation to the intake of each amino acid. The role of blood pressure as a potential mechanism was assessed in 267,642 (75%) participants.Results: After a median follow-up of 12.9 years, 4295 participants had an ischaemic stroke and 1375 participants had a haemorrhagic stroke. After correction for multiple testing, a higher intake of proline (as a percent of total protein) was associated with a 12% lower risk of ischaemic stroke (HR per 1 SD higher intake 0.88; 95% CI 0.82, 0.94). The association persisted after mutual adjustment for all other amino acids, systolic and diastolic blood pressure. The inverse associations of isoleucine, leucine, valine, phenylalanine, threonine, tryptophan, glutamic acid, serine and tyrosine with ischaemic stroke were each attenuated with adjustment for proline intake. For haemorrhagic stroke, no statistically significant associations were observed in the continuous analyses after correcting for multiple testing.Conclusion: Higher proline intake may be associated with a lower risk of ischaemic stroke, independent of other dietary amino acids and blood pressure.

- Objectives, setting and subjects: Atherosclerosis screening with ultrasound is non-invasive and can be used as part of risk communication. The potential of personalised and pictorial-based risk communication is assessed in VIPVIZA, a population-based randomised controlled trial that aims at optimising cardiovascular disease (CVD) prevention by investigating the impact of visualisation of subclinical atherosclerosis. The present aim was to explore cognitive and emotional reactions evoked by the intervention as well as attitudes to any implemented life style changes in VIPVIZA participants in the intervention group with improved health status and furthermore to study possible interactions between these factors. Understanding mechanisms of action was central since non-adherence to preventive guidelines are often faced in clinical practice. Design: In-depth interviews with 14 individuals were analysed with qualitative content analysis. Results: Cognitive and emotional processes were highly interlinked and described by the main theme Cognitive and emotional reactions in strong interplay for orchestration of health oriented behavioural change. The informants’ descriptions revealed two distinctly different psychological processes which constituted the two subthemes, Problem-focused coping and Encouragement-driven process. Conclusions: The results highlight that an interaction between emotional reactions and efficacy beliefs is important in facilitating behavioural change. Furthermore, the results underscore the importance of the risk message being perceived as clear, accurate, reliable and also emotionally engaging and thereby show why atherosclerosis screening and pictorial-based risk communication have the potential to contribute to effective CVD prevention strategies and shared decision making in primary care.

Tidskriftsartikel (refereegranskat)abstract
- Background: Pictorial communication about subclinical atherosclerosis can improve cardiovascular disease (CVD) risk, but whether it leads to long-term shifts in self-rated CVD risk (risk perception) and beliefs about possibility to influence personal risk (efficacy beliefs) is unknown.Purpose: To study the impact of personalized color-coded and age-related risk communication about atherosclerosis and motivational conversation, compared to traditional risk factor-based communication, on risk perception and efficacy beliefs. Also, whether risk perception increases with message severity.Method: The effect of the pragmatic RCT Visualization of Asymptomatic Atherosclerotic Disease for Optimum Cardiovascular Prevention (VIPVIZA) was analyzed using a linear mixed effects model with risk perception and efficacy believes at 1-year and 3-year follow up as dependent variables. Participants’ (n = 3532) CVD risk perception and efficacy beliefs were assessed with visual analog scales (0–10). Fixed effects were group (intervention vs control), time point (1 year or 3 years) and interaction between group and time point. Further, the models were adjusted for corresponding baseline measurement of the dependent variable and a baseline × time point interaction. Effect of pictorial color-coded risk in the intervention group was investigated using a corresponding mixed effects model, but with pictorial risk group (message severity) as exposure instead of intervention group.Results: After one year, the intervention group rated their CVD risk as higher (m = 0.46, 95% CI 0.32–0.59), with an effect also after 3 years (m = 0.57, 95% CI 0.43–0.70). The effect was consistent in stratified analyses by sex and education. Overall, no effect on efficacy beliefs was observed. In the intervention group, differences in CVD risk perception were found between participants with different color-coded risk messages on atherosclerosis status.Conclusion: Personalized, color-coded and age-related risk communication about atherosclerosis had an effect on risk perception with an effect also after 3 years, whereas overall, no effect on efficacy beliefs was observed.

From risk communication about asymptomatic atherosclerosis to cognitive and emotional reactions and lifestyle modification
- 2023

Ingår i: BMC Psychology. - : BioMed Central (BMC). - 2050-7283. ; 12:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Non-adherence in the general population to preventive guidelines on cardiovascular disease calls for an interdisciplinary approach acknowledging psychological factors of relevance for risk communication and lifestyle modification. Evidence is building up regarding the advantage of sharing arterial imaging evidence of subclinical atherosclerosis with asymptomatic individuals, but there is limited understanding of how this relates to mechanisms of importance for behavioural change. Longitudinal studies on associations between patients’ reactions and lifestyle modification are missing. The population-based randomized controlled trial VIPVIZA investigates the impact of pictorial information about subclinical atherosclerosis, added to traditional risk factor-based communication. The intervention includes a personalized, colour-coded and age-related risk communication strategy and a motivational conversation, and has been shown to reduce cardiovascular disease risk. Methods: In the present study we assessed cognitive and emotional reactions to the intervention, and how these reactions are associated to lifestyle modification. The participants’ evaluation of the risk communication was assessed in the intervention group (n=1749). Lifestyle modification was assessed with a lifestyle index based on physical activity, diet, smoking and alcohol consumption at baseline and after 3 years. Associations between cognitive and emotional response and lifestyle modification were tested with analyses of covariance in a subset of participants (n=714-857).Results: The intervention increased understanding of personal CVD risk, the possibility to influence the risk, and how to influence the risk. Severity of atherosclerosis was associated with emotional reactions, but emotions of strong negative valence were uncommon. Cognitive response and emotional arousal evoked by the intervention were positively associated with lifestyle modification, whereas negative emotions in isolation were not. High level of cognitive response in combination with high level of emotional arousal was found to be most beneficial for lifestyle modification.Conclusions: The results demonstrate the potential of communicating asymptomatic atherosclerosis with a pictorial, colour-coded and age-related strategy, also including a motivational conversation. Furthermore, the results show the importance of CVD risk communication evoking engagement, and that an interaction between cognitive and emotional reactions might be central for sustained lifestyle modification. Our results also indicate that, in an asymptomatic population, atherosclerosis screening may strengthen disease prevention and health promotion.

- Background: HIV/AIDS prevention has historically encountered many obstacles. Understanding the factors affecting HIV/AIDS prevention is central to designing and implementing suitable context-specific interventions. Research relating to HIV prevention in the Middle East and North African region is required to address the gradually increasing HIV epidemic.Objective: This study aimed to explore the perspectives of employees/health care professionals who are working or have worked within HIV prevention in Sudan and Yemen on the challenges and facilitating factors facing HIV prevention.Methods: A qualitative approach was employed using an open-ended questionnaire. Sixteen stakeholders from governmental and non-governmental agencies participated in the study. The questionnaire focused on the various challenges and facilitating factors facing HIV prevention as well as proposed possible solutions from the perspectives of the participants. The data were analysed using thematic analysis.Results: The study illustrated the similarities in context and HIV prevention systems between Sudan and Yemen. Thematic analysis resulted in three main themes: I) much is achieved despite difficulties; II) a programme left to be paralysed; this theme addressed the main obstacles facing HIV prevention in Sudan and Yemen generating a total of six sub-themes; III) comprehensive change is needed. The participants drew focus and attention to vital changes required to improve the delivery of HIV prevention services. Conclusion: Increased financial support for HIV prevention in Sudan and Yemen is urgently needed. De-stigmatisation and increased political support, advocacy and improved legislation for people living with HIV (PLHIV) are required for the sustainability and effectiveness of HIV prevention programmes in Sudan and Yemen. Civil society organisations must be aided and supported in their role in engaging key populations.

- Objectives: To explore how pictorial information on subclinical atherosclerosis affects GPs’ perception of patient cardiovascular disease (CVD) risk, their communication with patients, and GPs’ attitude to the treatment of CVD risk factors.Design, setting and subjects: Fifteen individual interviews were conducted between March 2014 and December 2016, with GPs who had received pictorial information regarding their patients’ subclinical atherosclerosis. The pictorial information was also received by the patients together with written information regarding atherosclerosis and CVD risk prior to the appointment with their GP. The interviews were recorded, transcribed and analyzed using qualitative content analysis.Results: Three categories were identified in the analysis. Increased knowledge makes a difference: When patients had more in-depth knowledge regarding atherosclerosis, the consultation became more patient-centered and moved towards shared decision making. This is real, not just a number: GPs described their risk assessment and the patient’s risk perception as more accurate with pictorial information about subclinical atherosclerosis. How to deal with the result–A passive to active approach: Some GPs acted promptly on the pictorial information while others took no action.Conclusion and implications: Pictorial information regarding patients’ subclinical atherosclerosis affected GPs’ assessment of CVD risk. The communication shifted towards shared decision-making although the GPs’ attitude to the result and treatment of CVD risk factors varied. Informing patients about examination results, both in writing and pictures, prior to a consultation can facilitate shared decision making and enhance preventive measures.Trial registration: https://clinicaltrials.gov/ct2/show/NCT01849575.KEY POINTS: Providing pictorial information about carotid ultrasound results and information regarding atherosclerosis to GPs and patients affects primary prevention:Informing patients about examination results prior to a consultation can be useful in clinical practice to enhance preventive measuresGPs experienced that increased patient knowledge resulted in a more patient-centered consultation and improved shared decision-makingGPs described their risk assessment and patients’ risk perception as more accurate with pictorial information about subclinical atherosclerosis.

Tidskriftsartikel (refereegranskat)abstract
- Ambient air pollution remains the major environmental cause of disease. Accurate assessment of population exposure and small-scale spatial exposure variations over long time periods is essential for epidemiological studies. We estimated annual exposure to fine and coarse particulate matter (PM2.5, PM10), and nitrogen oxides (NOx, NO2) with high spatial resolution to examine time trends 2000‒2018, compliance with the WHO Air Quality Guidelines, and assess the health impact. The modelling area covered six metropolitan areas in Sweden with a combined population of 5.5 million. Long-range transported air pollutants were modelled using a chemical transport model with bias correction, and locally emitted air pollutants using source-specific Gaussian-type dispersion models at resolutions up to 50 × 50m. The modelled concentrations were validated using quality-controlled monitoring data. Lastly, we estimated the reduction in mortality associated with the decrease in population exposure. The validity of modelled air pollutant concentrations was good (R2 for PM2.5 0.84, PM10 0.61, and NOx 0.87). Air pollution exposure decreased substantially, from a population weighted mean exposure to PM2.5 of 12.2µgm−3 in 2000 to 5.4µgm−3 in 2018. We estimated that the decreased exposure was associated with a reduction of 2719 (95% CI 2046–3055) premature deaths annually. However, in 2018, 65%, 8%, and 42% of residents in the modelled areas were still exposed to PM2.5, PM10, or NO2 levels, respectively, that exceeded the current WHO Air Quality Guidelines for annual average exposure. This emphasises the potential public health benefits of reductions in air pollution emissions.

- Aims: Health literacy, the degree to which individuals understand and act upon health information, may have a pivotal role in the prevention of cardiovascular disease (CVD), with low health literacy potentially explaining poorer adherence to prevention guidelines. We investigated the associations between health literacy, ultrasound-detected carotid atherosclerosis and cardiovascular risk factors.Methods: Baseline data (cross-sectional analysis) from a randomized controlled trial, integrated within the Västerbotten Intervention Program, Northern Sweden, was used. We included 3459 individuals, aged 40 or 50 years with ≥1 conventional risk factor or aged 60 years old. The participants underwent clinical examination, blood sampling, carotid ultrasound assessment of intima-media wall thickness (CIMT) and plaque formation, and answered a questionnaire on health literacy – the Brief Health Literacy Screen. The European Systematic Coronary Risk Evaluation and Framingham Risk Score were calculated.Results: About 20% of the participants had low health literacy. Low health literacy was independently associated with the presence of ultrasound-detected carotid artery plaques after adjustment for age and education, odds ratio (95% confidence interval) 1.54 (1.28–1.85), demonstrating a similar level of risk as for smoking. Health literacy was associated with CIMT in men. Low health literacy was associated with higher CVD risk scores. Sensitivity analyses with low health literacy set to 9% or 30% of the study sample, respectively, yielded essentially the same results.Conclusions: Low health literacy was independently associated with carotid artery plaques and a high level of CVD risk scores. Presenting health information in a fashion that is understood by all patients may improve preventive efforts.

- A broad range of aspects are needed to be taken into consideration in the design and development of personalized coaching systems based on artificial intelligence methodologies. This research presents the initial phase of joining different professional and stakeholder perspectives on behavior change technologies into a flexible design proposal for a digital coaching system. The diversity and sometimes opposed views on content, behavior, purposes and context were managed using a structured argument-based design approach, which also feed into the behavior of the personalized system. Results include a set of personalization strategies that will be further elaborated with the target user group to manage sensitive issues such as ethics, social norms, privacy, motivation, autonomy and social relatedness.

Being able to be stable : exploring primary weight maintenance as a public health strategy for obesity prevention
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background Overweight and obesity are considerable public health issues internationally as well as in Sweden. On a global level, the obesity prevalence has nearly doubled over the last 30 years. Currently in Sweden, more than one third of all women, and slightly more than half of all men, are either overweight or obese. The long-term results of obesity treatment programs are modest as reported by other studies. The importance of extending the focus to not only obesity treatment, but also prevention of weight gain, has therefore been emphasized.Aim The overall aim of this thesis is to explore the concept of primary weight maintenance (PWM) and to increase the knowledge of the attitudes, behaviours, strategies and surrounding circumstances that are important for PWM in a Swedish middle-aged population.Material and methods All study participants were recruited based on their previous participation in a health survey in their home setting; The Västerbotten Intervention Programme (VIP) in Västerbotten Sweden (paperI-IV), or the Upstate Health and Wellness Study in Upstate New York (IV), USA. All subjects had participated twice, with a time period of ten years between health surveys. The prevalence of obesity between the years 1990-2004 was calculated for VIP participants (paper I). Ten-year non-gain (lost weight or maintained body weight within 3% of baseline weight) or weightgain (≥3%) was calculated for individuals aged 30, 40, or 50 years at baseline. A multivariate logistic regression model was built to predict weight non-gain. In-depth interviews were conducted with 23 maintainers and four slight gainers in Sweden and analysed using Grounded Theory (paper II). A questionnaire study was conducted including 2138 Swedish and 2134 US participants (paper III and IV). Analysis of variance (ANOVA), correlation, and linear regression were performed to identify attitudes, strategies, and behaviours that are predictive of PWM in different age, sex and BMI subgroups in Sweden (paper III). Further, the pattern of ten-year weightchange (% and kg) in 1999-2009 was calculated for Swedish and US women within different subgroups (paper IV). ANOVA, correlation and chi-squaretests were conducted to contrast eating and exercise habits between the two countries that may explain the differences in weight change.Results The prevalence of obesity (BMI ≥30) in Västerbotten increased from 9.4% in 1990 to 17.5% in 2004 (I). Older age, being female, being overweight at baseline, later survey year, baseline diagnosis of diabetes, and lack of snuff use increased the chances of not gaining weight. Based on the in-depth interviews, describing attitudes, behaviours and strategies of importance for PWM, a model was constructed (II). Weight maintenance was characterized as “a tightrope walk” and four strategies of significance for PWM were described as “to rely on heritage”, “to find the joy”, “to find the routine” and “to be in control”. The questionnaire study aimed at identifying predictors of PWM in different age, sex and BMI groups (III). The pattern of significant predictors was widely disparate between different subgroups. Of 166 predictors tested, 152 (91.6%) were predictive of PWM in at least one subgroup. However, only 4.6% of these were significant in half of the subgroups or more. The mean percent weight changes (in all cases weightgain), between 1999-2009 for Swedish and US women, were 4.9% (SD=5.8) and 9.1% (SD=13.7) respectively (p for t-test˂0.001) (IV). For the US women, the largest weight change occurred among the 30 year olds for all three BMI strata. For the Swedish, it was seen among overweight and obese 30 year old women. The largest difference in ten-year weight change between the two countries for any two matched subgroups was seen in normal weight 30 year olds. Significantly more of the women in this Swedish subgroup stated having more of healthy behaviours. However, there was a tendency for unhealthy behaviours to be strongly associated with greater weight gain in the US, but much less so in Sweden.Conclusion: Younger individuals, those of normal body weight, and those without health conditions (e.g. diabetes type 2) and cardiovascular riskfactors – were the least likely to maintain their weight over the 10 year period (I). Educational efforts on the prevention of overweight and obesity should therefore be broadened to include those individuals. The in-depth interview study showed great variety with regard to attitudes, strategies and behaviours important for PWM (II). The results from this study informs health personnel about the need to tailor advice related to body weight, not only to different sub-groups of individuals trying to lose weight but also to subgroups of primary weight maintainers who are trying to maintain weight. This statement was also supported by the questionnaire data, where the large disparity in the pattern of significant variables between subgroups suggests that these interventions should be tailored to the person’s demographic (age,sex and BMI) (III). Paper IV showed that even though the prevalence of obesity among Swedish women has increased substantially during these ten years, it has not kept pace with the increase in the US. One explanation for this may be that normal 30 year old Swedish women have more healthy behaviours than do US women. However, the insensitivity of the Swedish women to weight gain for healthy versus unhealthy alternatives may also be a factor. If the exact reason behind this phenomenon can be identified this may contribute to a deeper understanding of PWM both in Sweden and the US.
