Factors that influence personal perceptions of the risk of an acute myocardial infarction

Social power and perceived risk of contagious disease: High power leads to lower risk estimation of catching COVID-19

An accurate estimation of COVID-19 contagion risk is important in terms of understanding the dynamic of disease transmission and health behavior. Previous research has documented that many health-related variables influence the risk estimation of communicable diseases. We expanded the current understanding by investigating whether health-irrelevant factors-such as one's sense of power-can have a systematic and consequential impact on perceived risks of catching the coronavirus. Based on the social distance theory of power, we propose that people in a higher power position develop a greater sense of social distance than those in a lower power position, which may in turn predispose the former to think that they are less likely to catch contagious diseases from other people. In Study 1, we provided correlational evidence that the personal sense of power was associated with the underestimation of contagion probability in Chinese university students. In Study 2, we established the causal relationship between power and concerns for contagious diseases in nonstudent adults and revealed the mediating role of social distance in the observed effect. Overall, these results, for the first time, indicate that power can elevate perceived social distance, exerting downstreaming effects on health cognition during the COVID-19 pandemic.

Patient and provider perspectives on barriers to myocardial infarction care among persons with human immunodeficiency virus in Tanzania: A qualitative study

INTRODUCTION

People with HIV (PLWH) have an increased risk myocardial infarction (MI), and evidence suggests that MI is under-diagnosed in Tanzania. However, little is known about barriers to MI care among PLWH in the region.

METHODS

In this qualitative study grounded in phenomenology, semi-structured interviews were conducted in northern Tanzania. Purposive sampling was used to recruit a diverse group of providers who care for PLWH and patients with HIV and electrocardiographic evidence of prior MI. Emergent themes were identified via inductive thematic analysis.

RESULTS

24 physician and patient participants were interviewed. Most participants explained MI as caused by emotional shock and were unaware of the association between HIV and increased MI risk. Providers described poor provider training regarding MI, high out-of-pocket costs, and lack of diagnostic equipment and medications. Patients reported little engagement with and limited knowledge of cardiovascular care, despite high engagement with HIV care. Most provider and patient participants indicated that they would prefer to integrate cardiovascular care with routine HIV care.

CONCLUSIONS

PLWH face many barriers to MI care in Tanzania. There is a need for multifaceted interventions to educate providers and patients, improve access to MI diagnosis, and increase engagement with cardiovascular care among this population.

40-65 Yaş Erkeklerin Gerçek ve Algıladıkları Kardiyovasküler Hastalık Risklerinin Karşılaştırılması: Bir Kesitsel Çalışma

Objective: To determine the actual cardiovascular diseases risk and to compare it with the perceived risk in 40-65 years old men. Methods: We conducted a cross-sectional study in a population determined to be 21.039 men and sample consisted of 400 men. The actual cardiovascular diseases risks of these respondents were calculated using HeartScore, classified as low, moderate, high, or very high. The respondents’ perception of their cardiovascular disease’s risks was categorized as wrong optimists/pessimists and realists. We used multivariate logistic regression models to determine the relationships between perceived cardiovascular diseases risk and independent variables (age, diabetes, hypertension, etc.). Required ethics committee and institutional permissions were obtained for the duly conduct of the study. Results: It was determined in our study that while 8.3% (n=33) of the men had a high-risk level for cardiovascular disease, 52.5% (n=210) had a very high level. Forty-eight percent of the participants perceive their CVD risks to be lower than they are and 23.8% to perceive it higher than they are. Correct estimation rate of CVD risk was 28.2%. The variables affecting the actual cardiovascular diseases risk were diastolic blood pressure, body mass index, and level of physical activity. 13.3% (n=53) of respondents perceived their cardiovascular diseases risks as high and 8% (n=32) as very high. The variables affecting an incorrect perceived cardiovascular diseases risk are being 61-65 years of age (odds ratio=0.34, 95% confidence interval: 0.16-0.73) and a diagnosis of diabetes mellitus (odds ratio=0.45, 95% confidence interval: 0.20-0.99). Conclusion: We observed that more than half of the residents were at a very high level of risk for cardiovascular disease, and approximately one out of every two respondents perceived their risk of cardiovascular disease to be lower than the actual risk. It is recommended risk reducing behaviors be developed and awareness of risk be raised.

Knowledge, attitudes, and preventive practices regarding ischemic heart disease among HIV-positive individuals in northern Tanzania

OBJECTIVES

To describe knowledge, attitudes, and practices (KAP) regarding ischemic heart disease (IHD) among adults with HIV in Tanzania.

METHODS

Adults presenting for routine HIV care at a clinic in northern Tanzania were consecutively enrolled and were administered a standardised KAP survey. For each participant, an IHD knowledge score was calculated by tallying correct answers to the IHD knowledge questions, with maximum score 10. Individual 5-year risk of cardiovascular event was calculated using the Harvard NHANES model. Associations between participant characteristics and IHD knowledge scores were assessed via Welch's t-test.

RESULTS

Among the 500 participants, the mean (SD) age was 45.3 (11.4) years and 139 (27.8%) were males. Most participants recognised high blood pressure (n = 313, 62.6%) as a risk factor for IHD, but fewer identified diabetes as a risk factor (n = 241, 48.2%), or knew that aspirin reduces the risk of a secondary cardiovascular event (n = 73, 14.6%). Higher IHD knowledge score was associated with post-primary education (mean 6.27 vs. 5.35, p = 0.001) and with >10% 5-year risk of cardiovascular event (mean 5.97 vs. 5.41, p = 0.045). Most participants believed there were things they could do to reduce their chances of having a heart attack (n = 361, 72.2%). While participants indicated that they adhered to their prescribed medications (n = 488, 97.6%), only 106 (21.2%) attended regular health check-ups.

CONCLUSION

Efforts are needed to improve gaps in IHD knowledge, and increase uptake of cardiovascular preventative practices among Tanzanian adults with HIV.

Good general health and lack of family history influence the underestimation of cardiovascular risk: a cross-sectional study

AIMS 

Underestimation of cardiovascular risk may interfere with prevention of cardiovascular diseases (CVDs). We investigate whether general health and family history of myocardial infarction (MI) are associated with underestimation of perceived cardiovascular risk, and if the participants' calculated risk modifies that association.

METHODS AND RESULTS 

The analysis sample consisted of 526 individuals, 50-64 years old, from a population-based cohort study. Information on general health (poor/fairly good, good, and very good/excellent), family history of MI, and self-perceived risk relative to others of similar age and sex were collected though a web-based survey. Participants were categorized into underestimation (n = 162, 31%), accurate estimation (n = 222, 42%), and overestimation (n = 142, 27%) of cardiovascular risk by comparing calculated Systematic Coronary Risk Estimation (SCORE) with self-perceived risk. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for underestimation vs. accurate estimation of cardiovascular risk were computed using logistic regression (n = 384). Very good general health (OR 2.60, 95% CI 1.10-6.16) and lack of family history (OR 2.27, 95% CI 1.24-4.18) were associated with underestimation of cardiovascular risk. The associations were modified by the participants' calculated risk level; the association was stronger for high-risk individuals; without family history OR 22.57 (95% CI 6.17-82.54); with very good/excellent health OR 15.78 (95% CI 3.73-66.87).

CONCLUSION 

A good general health and the lack of family CVD history can obscure the presence of other risk factors and lead to underestimation of cardiovascular risk, especially for high-risk individuals. It is, therefore, crucial to address the fact that the development of CV disease may be silent and multifactorial.

Knowledge and cardiovascular disease risk perception from the perspectives of prisoners and staff in a Scottish prison: a qualitative study

PURPOSE

Prisoners have an increased risk of cardiovascular disease (CVD) compared to the general population. Knowledge and risk perception of CVD can influence engagement in preventative behaviours that lower an individual's CVD risk. This paper aims to explore prisoners' knowledge of CVD, and prisoners and staff's perceptions of prisoners' CVD risk.

DESIGN/METHODOLOGY/APPROACH

This was a qualitative study in which semi-structured interviews were conducted with 16 prisoners and 11 prison and National Health Services staff in a Scottish prison. Data were analysed thematically using the framework method.

FINDINGS

Most prisoners had limited knowledge of CVD as they could not describe it or could only identify one or two risk factors or cardiovascular events. Both prisoners and staff viewed prisoners' CVD risk as either pertaining to one individual, or pertaining to the general prisoner population. Unhealthy behaviours that were believed to increase CVD risk were linked to three perceived consequences of imprisonment: mental health problems, boredom and powerlessness.

ORIGINALITY/VALUE

To the best of the authors' knowledge, this is the first study to explore the CVD knowledge of prisoners, and perceptions of CVD risk from the perspectives of prisoners and prison staff. Findings from this study indicate that CVD education needs to be a priority for prisoners, addressing knowledge of CVD, its risk and risk perceptions. Additionally, the findings indicate that individual and socio-environmental factors linked to prisoners' CVD risk need to be targeted to reduce this risk. Future research should focus on socio-environmental interventions that can lead to reducing the CVD risk of prisoners.

Derivation of a Coronary Age Calculator Using Traditional Risk Factors and Coronary Artery Calcium: The Multi-Ethnic Study of Atherosclerosis

Background The optimal method for communicating coronary heart disease (CHD) risk to individual patients is not yet clear. Recent research supports the concept of "coronary age" for more effective risk communication. We defined an individual's coronary age as the age at which an average healthy individual would have an equivalent estimated CHD risk as that calculated for the index individual, building on our previously validated MESA (Multi-Ethnic Study of Atherosclerosis) 10-year CHD Risk Score equations with and without coronary artery calcium (CAC). Methods and Results We derived a coronary age by (1) calculating the MESA 10-year CHD risk; (2) mathematically setting this equal to an equation describing risk of an average healthy MESA participant, as a function of age; and (3) solving for age. The risk discrimination of the resultant coronary age was compared with that of chronological age, the MESA CHD Risk Score, and CAC alone. Approximately 95% of coronary age values ranged from 30 years less to 30 years higher than chronological age. Although the mean chronological age of individuals experiencing CHD events compared with those free of events was 67.4 versus 61.8 years, the difference in coronary age including CAC was larger (80.6 versus 62.8 years). Coronary age with CAC had identical predictive ability to that of MESA CHD Risk Score and outperformed chronological age and CAC alone. Conclusions The newly derived coronary age is a convenient transformation of MESA CHD Risk, retaining very good risk discrimination. This easy-to-communicate tool will be available for patients and clinicians, potentially facilitating risk communication in routine care.

Are people at high risk for diabetes visiting health facility for confirmation of diagnosis? A population-based study from rural India

Background: India is witnessing a rising burden of type 2 diabetes mellitus. India’s National Programme for Prevention and Control of Diabetes, Cancer, Cardiovascular diseases and Stroke recommends population-based screening and referral to primary health centre for diagnosis confirmation and treatment initiation. However, little is known about uptake of confirmatory tests among screen positives.

Objective: To estimate the uptake of confirmatory tests and identify the reasons for not undergoing confirmation by those at high risk for developing diabetes.

Methods: We analysed data collected under project UDAY, a comprehensive diabetes and hypertension prevention and management programme, being implemented in rural Andhra Pradesh, India. Under UDAY, population-based screening for diabetes was carried out by project health workers using a diabetes risk score and capillary blood glucose test. Participants at high risk for diabetes were asked to undergo confirmatory tests. On follow-up visit, health workers assessed if the participant had undergone confirmation and ask for reasons if not so.

Results: Of the 35,475 eligible adults screened between April 2015 and August 2016, 10,960 (31%) were determined to be at high risk. Among those at high risk, 9670 (88%) were followed up, and of those, only 616 (6%) underwent confirmation. Of those who underwent confirmation, ‘lack of symptoms of diabetes warranting visit to health facility’ (52%) and ‘being at high risk was not necessary enough to visit’ (41%) were the most commonly reported reasons for non-confirmation. Inconvenient facility time (4.4%), no nearby facility (3.2%), un-affordability (2.2%) and long waiting time (1.6%) were the common health system-related factors that affected the uptake of the confirmatory test.

Conclusion: Confirmation of diabetes was abysmally low in the study population. Low uptake of the confirmatory test might be due to low ‘risk perception’. The uptake can be increased by improving the population risk perception through individual and/or community-focused risk communication interventions.

A Predictive Model of Perceived Susceptibility during the Year before Coronary Artery Bypass Grafting

Background: Based on the protective health model, one of the most important components of etiological factors leading to protective health behaviors is perceived risk or perceived susceptibility. Accordingly, the present study was conducted to assess the uncontrolled and controlled effects of some factors in predicting perceived susceptibility among coronary artery bypass graft (CABG) patients.

Methods: The data for the present cross-sectional study were gathered via assessment of 1052 CABG patients who referred to an outpatient cardiac rehabilitation clinic in a hospital in Iran between 2010 and 2014. The patients completed a checklist containing demographics, risk factors, and a single closed-ended question regarding perceived susceptibility at the beginning of their rehabilitation program. Binary logistic regression analysis was applied to identify the demographic and clinical correlations related to perceived susceptibility.

Results: Totally, 776 (73.8%) of the 1052 participants were male. The mean age of the patients was 58.0 ± 9.1 years. The results revealed that only 13.7% of the patients had perceived susceptibility; in addition, higher age (p value = 0.003) and family history of cardiac diseases (p value = 0.001) were able to significantly predict perceived susceptibility. When the demographic variables were controlled, once again age and family history of cardiac diseases were able to significantly increase perceived susceptibility by approximately 1.04 and 29.6 times, respectively.

Conclusion: Our results revealed that higher age and family history of cardiac diseases were able to significantly predict perceived susceptibility among our CABG patients.

Lay Awareness of the Relationship between Age and Cancer Risk

BACKGROUND

Cross-sectional studies suggest many people are unaware that cancer risk increases with age, but this misbelief has rarely been studied prospectively, nor are its moderators known.

PURPOSE

To assess whether people recognize that cancer risk increases with age and whether beliefs differ according to gender, education, smoking status, and family history of cancer.

METHODS

First, items from the cross-sectional Health Information National Trends Survey (n = 2069) were analyzed to examine the association of age and perceived cancer risk. Second, the prospective National Survey of Midlife Development in the United States (n = 3896) was used to assess whether perceived cancer risk changes over a decade. Third, beliefs about the age at which cancer occurs were analyzed using the US Awareness and Beliefs about Cancer survey (n = 1080). As a comparator, perceived risk of heart disease was also examined.

RESULTS

Cross-sectionally, older age was associated with lower perceived cancer risk but higher perceived heart disease risk. Prospectively, perceived cancer risk remained stable, whereas perceived heart attack risk increased. Seventy percent of participants reported a belief that cancer is equally likely to affect people of any age. Across three surveys, women and former smokers/smokers who recently quit tended to misunderstand the relationship between age and cancer risk and also expressed relatively higher perceived cancer risk overall.

CONCLUSIONS

Data from three national surveys indicated that people are unaware that age is a risk factor for cancer. Moreover, those who were least aware perceived the highest risk of cancer regardless of age.

Hong Kong Chinese adults' knowledge of exercise recommendations and attitudes towards exercise

Background

Physical inactivity is known to be one of the major risk factors for many chronic conditions.

Aim

To determine Hong Kong Chinese adults’ physical activity (PA) knowledge, its relationship with certain variables including sex, education, age, and its correlation with different types of chronic diseases, such as heart disease, cerebrovascular disease, diabetes mellitus, obesity, and others. The Hong Kong Chinese adults' general attitudes towards PA will also be examined.

Design & setting

Cross-sectional study in one primary care centre.

Method

A randomized sample of Chinese adults aged >18 years with anonymous self-administered questionnaires.

Results

The mean percentage of correct responses for exercise guidelines was 62.3%, 84.5% for traditional PA, and 48.4% for lifestyle PA, respectively. Traditional PA refers to exercises which use large muscle groups. Lifestyle PAs include activities which can be done throughout the day. The total mean percentage of correct responses was 67% (knowledge score 13.4 +/– 3.34). There were no significant differences between PA knowledge and sex, education levels, age groups, and presence of chronic diseases (P>0.05), but the knowledge level for lifestyle PA was less than that of traditional PA (P<0.001). A weak correlation was found between responders’ activeness for a health benefit and the PA knowledge levels (P>0.05). Two hundred and sixy-six (93.3%) responders reported a willingness to maintain or start exercise.

Conclusion

The results suggest a need for more education about the latest PA recommendations, especially lifestyle PA. The weak correlation between PA knowledge and actual behaviour showed that PA knowledge itself might not affect PA behaviour. The enhancement of the general public’s knowledge, motivation, and psychosocial support along with stage-of-change interventions and the provision of counselling skills may result in PA behaviour change, which in turn can lead to the achievement of health benefits.

To Be Stricken with Acute Myocardial Infarction: A Grounded Theory Study of Symptom Perception and Care-seeking Behaviour

The process of perceiving symptoms of illness is complex, and many patients delay seeking care when symptoms of acute myocardial infarction occur. However delayed treatment can have great consequences for the prognosis. This article reports on a grounded theory study, the aim of which was to increase our understanding of the individual’s thoughts, feelings and actions at the onset of an acute heart attack. Qualitative analysis of semi-structured interviews revealed four different ways of perceiving the onset of symptoms: understanding, misinterpretation, amazement and disregard. The symptom perception categories were related to two core categories labelled health beliefs and acute reactions. Some persons were aware of risks for coronary heart disease and were ready to seek care immediately. Several others had illusions of invulnerability. Such illusions caused people to delay seeking care at the onset of symptoms of myocardial infarction.

Testing a Model to Reveal the Predictive Mechanism of Care-Seeking Decisions Among Patients With Acute Myocardial Infarction

BACKGROUND

Extensive research has been conducted to examine the factors affecting care-seeking decisions in patients with acute myocardial infarction (AMI). Such a decision-making process is multifactorial, and its underlying mechanism is yet to be determined.

OBJECTIVES

Our aim was to test a theoretically integrated model to identify the mechanisms underlying patients' care-seeking decisions in the context of AMI.

METHODS

On the basis of both empirical and theoretical evidence, we proposed that patients' care-seeking decisions are driven by 2 sequential perceptual-cognitive processes concerned with illness labeling and interpretation, as well as the contextual influences of perceived barriers to care seeking and cues from others. A sample of 301 patients was recruited to test this model using structural equation modeling.

RESULTS

The model testing revealed good fit with the data (χ = 38.48, df = 30, P = .72; root-mean-square error of approximation = 0.03, normed fit index = 0.96, nonnormed fit index = 0.98, and comparative fit index = 0.99) and explained 46% of the variance in AMI care-seeking delay. Successful action relied on whether patients could correctly attribute the symptom experience to AMI, were aware of their own susceptibility to the condition, and had a good understanding of how the disease manifested itself. Lowering perceived barriers and positive cues from others in advising care seeking played favorable roles to promote care-seeking behaviors.

CONCLUSIONS

This integrative theoretical model is shown to be valid in explaining care-seeking delay among AMI patients and can guide the development of interventions to promote appropriate care-seeking behaviors among high-risk individuals.

Psychosocial Factors Associated With Risk Perceptions for Chronic Diseases in Younger and Middle-Aged Women

Perceptions of disease risk play an important role in motivating people to adopt healthy behaviors. However, little is known about psychosocial factors that influence women's perceived risk for developing disease. The present study investigated the extent to which individual traits, social influences, objective risk factors, and demographic characteristics were associated with women's risk perceptions for cardiovascular disease, breast cancer, and lung cancer. Using structural equation modeling, we examined hypothesized associations among 452 younger (ages 18-25 years) and 167 middle-aged (ages 40-64 years) women. A greater number and variety of factors were associated with middle-aged women's risk perceptions compared to younger women. For both groups, some objective risk factors were associated with risk perceptions; yet, associations also existed between multiple psychosocial variables (optimism, health locus of control, social exposure to disease, perceived stigma) and risk perceptions. Results suggested that women may base their risk estimates on factors beyond those considered important by healthcare providers.

'If you have a problem with your heart, you have a problem with your life': Self-perception and behaviour in relation to the risk of ischaemic heart disease in people living with HIV

BACKGROUND

Ischaemic heart disease (IHD) is a global health problem and specifically relevant in the African context, as the presence of risk factors for IHD is increasing. People living with the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) (PLWHA) are at increased risk for IHD due to increased longevity, treatment-specific causes and viral effects.

AIM

To determine the self-perception and behaviour in relation to risk for IHD in a cohort of South African PLWHA.

METHODS

A qualitative study using semi-structured interviews with a card-sort technique was used to gather data from 30 individuals at an HIV clinic in Johannesburg. Descriptive analysis and conventional content analysis were done to generate the findings.

RESULTS

The median age of the cohort was 36.5 (31.8-45.0) years and they were mostly women (n = 25; 83.3%) who were employed (n = 17; 56.7%) and supporting dependents (n = 26; 86.7%). Fifteen (50%) participants did not perceive themselves at risk of IHD and reported having adequate coping behaviour, living a healthy lifestyle and being healthy since initiating therapy. Twelve (40%) did feel at risk because they experienced physical symptoms and had poor behaviour. Knowledge and understanding related to IHD, insight into own risk for IHD and health character in a context of HIV infection were three themes.

CONCLUSION

This study highlights that participants did not perceive themselves to be at risk of IHD due to their HIV status or antiretroviral management. Education strategies are required in PLWHA to inform their personal risk perception for IHD.

The Effect of Cardiac Education on Knowledge and Adherence to Healthy Lifestyle

The purpose of this study was to test the effect of cardiac educational program on the level of knowledge and adherence to healthy lifestyle among patients with coronary artery disease in the north of Jordan. Pretest–posttest design was used. Eighty-four patients completed the posttest questionnaire. Knowledge and adherence to healthy lifestyle were measured at baseline and at 1 month after the application of the program. Paired t-test was used to analyze the data. The results showed that the change in the mean knowledge scores (10.50), p < .01 was statistically significant 1 month after the application of the program. In addition, the change in the mean adherence to healthy lifestyle scores (33.30), p < .01 was statistically significant 1 month after the application of the cardiac educational program. Implementing cardiac educational programs help enhance knowledge and adherence to healthy lifestyle among patients with coronary artery disease in north of Jordan.

Pacific Islanders' perceived risk of cardiovascular disease and diabetes

PURPOSE

To explore literature on Pacific Islanders' perceived risk of cardiovascular disease (CVD) and diabetes.

METHOD

A search of literature databases for English-language perceived risk research published from 2000 to 2008.

RESULTS

Few studies targeting perceived risk of CVD (n = 6) and diabetes (n = 4) included minority participants. No studies targeted Pacific Islanders exclusively. Overall, Pacific Islanders and other minority groups inaccurately perceive their risk of these conditions. No studies explored cultural relevancy or measurement of perceived risk.

IMPLICATIONS

Perceived risk, an integral part of health behavior change theories, is greatly understudied in Pacific Islanders. Perceived risk research for CVD and diabetes is sparse for any minority group. More research is needed to develop socioculturally appropriate interventions that promote accurate risk perceptions for both diseases and facilitate adoption of health behaviors. Ultimately, these behaviors will reduce the onset and devastating consequences of CVD and diabetes in Pacific Islanders and other minority populations.

Passing years, changing fears? Conceptualizing and measuring risk perceptions for chronic disease in younger and middle-aged women

As is true for many behavioral theory constructs, no consensus exists on how best to measure perceived risk; therefore, it is unclear whether different measures of disease risk perception are conceptually equivalent and whether such measures are equally appropriate for people with different objective disease risk. To investigate these issues, we used four commonly utilized risk perception items (measuring beliefs about personal risk, others' risk, disease prevalence, and mortality) to assess susceptibility to cardiovascular disease, breast cancer, and lung cancer among 454 younger (ages 18-25) and 169 middle-aged (40-64) women. We examined age- and ethnicity-related differences in participants' responses to the items. We also used structural equation modeling to test whether these items reflect a multidimensional, disease-specific latent construct of risk perception; and to test whether consistency exists in participants' disease-specific risk perceptions. Despite differences in responses to individual items, hypothesized models of perceived risk fit both age groups, suggesting that risk perception can be conceptualized in younger and middle-aged women as a multidimensional construct that is specific to disease yet reflective of global risk-related beliefs.

Theoretical considerations in reducing risk for cardiovascular disease: implications for nursing practice

AIMS AND OBJECTIVES

This article describes the theoretical foundation of risk perception as a key component of changing deleterious health behaviours associated with cardiovascular disease (CVD). Furthermore, perception in increasing cardiovascular risk-reducing behaviours in a socio-cultural framework is discussed, and an empirical development conceptual model presented.

BACKGROUND

Perception of risk is strongly linked with health-seeking behaviours. Understanding how to reduce risk and maximise cardiovascular health is an increasing focus of clinicians, researchers and policy makers. Increasing cultural diversity in contemporary society means that nurses need to develop and evaluate interventions in this context.

DESIGN

An integrative literature review.

METHOD

An integrative literature review method was used to assess conceptual models relating to risk perception of developing CVD. On the basis of the findings, a model was developed to inform future intervention studies, considering individual, social and cultural factors.

DISCUSSION

Studies examining CVD and health behaviours report that there is limited concordance between actual and perceived risk in people with CVD. This mismatch risk likely impedes the adoption of risk-reducing behaviours.

CONCLUSION

There is a critical need to develop interventions for enhancing an accurate perception of CVD risk considering not only individual but social factors.

RELEVANCE TO CLINICAL PRACTICE

There is limited correlation between knowledge and behaviours, and health behaviours are influenced by individual, social and cultural factors. Appraising the congruence between actual and perceived risk is an important step in developing effective care plans to reduce cardiovascular risk.

Perceptions of risk: understanding cardiovascular disease

Cardiovascular disease (CVD) is still the leading cause of death and disability worldwide despite the availability of well-established and effective preventive options. Accurate perception of a patient’s risk by both the patient and the doctors is important as this is one of the components that determine health-related behavior. Doctors tend to not use cardiovascular (CV) risk calculators and underestimate the absolute CV risk of their patients. Patients show optimistic bias when considering their own risk and consistently underestimate it. Poor patient health literacy and numeracy must be considered when thinking about this problem. Patients must possess a reasonably high level of understanding of numerical processes when doctors discuss risk, a level that is not possessed by large numbers of the population. In order to overcome this barrier, doctors need to utilize various tools including the appropriate use of visual aids to accurately communicate risk with their patients. Any intervention has been shown to be better than nothing in improving health understanding. The simple process of repeatedly conveying risk information to a patient has been shown to improve accuracy of risk perception. Doctors need to take responsibility for the accurate assessment and effective communication of CV risk in their patients in order to improve patient uptake of cardioprotective lifestyle choices and preventive medications.

Risk perception and its association with cardiac risk and health behaviors among urban minority adults: the Bronx Coronary Risk Perception study

PURPOSE

Examine the relationship among risk perceptions, health behaviors, and a measure for actual risk of coronary heart disease (CHD).

DESIGN

Cross-sectional survey.

SETTING/SUBJECTS

Adults from three outpatient medical clinics with at least one CHD risk factor.

MEASURES

Perceived risk using the new Coronary Risk, Individual Perception (CRIP) scale, an index of CHD risk, and summary scores for self-reported diet and exercise.

ANALYSIS

Bivariate associations using Spearman rank and Kruskal-Wallis; multiple regression models for outcomes (health behaviors).

RESULTS

The 16-item CRIP scale had acceptable internal consistency (alpha = 0.76; interitem total correlation = 0.34 +/- 0.17). The response rate was 80.3%, and the mean age of 256 respondents was 56.6 (+/- 9.9) years; 70% were women, 63% Hispanic, and 27% black. CRIP scores were inversely associated with low fat/high fiber intake (r = - 0.17; p = .007) and exercise (r = -0.19; p = .003). Among respondents with three or more CHD risk factors (n = 132), 44% perceived themselves to be at low risk for CHD. In multivariable models, men with high CRIP scores had higher fat intake than women (p = .02), but men exercised more (p = .04).

CONCLUSIONS

In this study, gender moderated the relationship between risk perception and health behaviors, and many respondents underestimated their risk of CHD. Behavioral intervention research aimed at reducing cardiometabolic risk in minority populations should resolve differences between perceived and actual risk of CHD to foster lifestyle changes and examine temporal relationships between risk perception and health behaviors.

Disparities in knowledge of heart attack and stroke symptoms among adult men: an analysis of behavioral risk factor surveillance survey data

CONTEXT

The staggering burden of myocardial infarction and stroke in men and for men of African-American descent in particular provided the impetus for this study. Morbidity and mortality from these vascular disorders can be reduced by early treatment, which requires correct prehospital identification of symptoms.

OBJECTIVE

The purpose of this study was to assess current knowledge of myocardial infarction and stroke symptoms and to examine if there were disparities in knowledge of these among U.S. males.

DESIGN

This is a cross-sectional study analyzing public use 2003-2005 Behavioral Risk Factor Surveillance Survey data. Univariate, bivariate and multivariate techniques were used.

SETTING

Random-digit-dial telephone survey focused on health risk factors and behaviors. Data collection was done under the direction of the Centers for Disease Control and Prevention.

PATIENTS OR OTHER PARTICIPANTS

Data collections targeted noninstitutionalized U.S. adults 18-90 years of age. This study focused on the adult male population.

MAIN OUTCOME MEASURES

From the 13 heart attack and stroke symptom knowledge questions asked on the survey, a heart attack and stroke knowledge score was computed for each respondent.

RESULTS

Multivariate analysis revealed that both Caucasian and African-American men earning low scores on the knowledge questions were more likely to: have less than a high-school education, have deferred medical care in the past 12 months because of cost and not have health insurance in the past 12 months. African-American men were also more likely to live in households with annual incomes < $35,000 and were more likely to not have a primary care provider; this was not true for Caucasian men.

CONCLUSIONS

There is a disparity in myocardial infarction and stroke symptom knowledge along racial and socioeconomic lines. African-American males, poorer individuals and those with lower levels of education had significantly lower scores. Since these subgroups are also among those at higher risk for stroke and myocardial infarction, targeting measures to enhance knowledge in these groups might yield more benefit than programs aimed at the general male populace.

Perceptions of coronary heart disease risk in Korean immigrants with type 2 diabetes

PURPOSE

The purpose of this study was to examine coronary heart disease (CHD) risk perception, risk factor status, and factors associated with CHD risk perception in Korean immigrants with type 2 diabetes mellitus.

METHODS

A community sample of 143 Korean adults with type 2 diabetes, aged 30 to 80 years old, completed questionnaires and biological measures. A multiple regression analysis was conducted to evaluate the relationships between CHD knowledge, general health, smoking, medications for CHD risk factors, demographic variables (independent variables), and the perception of CHD risk (dependent variable).

RESULTS

Participants had low perception of CHD risk, with most (76.9%) indicating their risk to be the same or lower than people of the same age and sex in the general population. Overall, CHD risk factor control was suboptimal according to American Diabetes Association guidelines. Only 41.3% of participants met the HbA1c goal of less than 7%. More than half (55%) had uncontrolled blood pressure, and a similar proportion (53.6%) had higher low-density lipoprotein cholesterol than the target goal. CHD knowledge and self-reported general health influenced the perception of CHD risk. More CHD knowledge and poor general health were associated with higher perception of CHD risk.

CONCLUSIONS

To increase the perception of CHD risk in Korean immigrants with type 2 diabetes, diabetes educators and clinicians should educate such patients about CHD risk factors and discuss their risk status at every visit. Those who report their health to be good deserve particular attention.

Why do women underestimate the risk of cardiac disease? A literature review

BACKGROUND

Despite the quantity of information available to women about risk factors for cardiovascular disease (CVD), many women do not perceive this risk.

AIM

This paper seeks to identify factors in the published literature that influence women's risk perception of heart disease, and how these perceptions influence health outcomes.

METHOD

A literature search from 1985 to 2006 using the CINAHL, Medline, Embase and PsycINFO electronic databases was undertaken. The keywords used were 'perceived risk', 'cardiac risk factors', 'cardiovascular disease', 'risk misconception', and 'heart disease', combined with 'women' and/or 'gender'. Additional data was obtained by manual searches of bibliographies of articles identified in the electronic searches, and Internet searches.

FINDINGS

Until the late 1980s, CVD was perceived as a disease which primarily affected men, as few large clinical trials recruited women. This resulted in a lack of data documenting the relationship between known risk factors and gender. Until recently, health professionals have not focused on disseminating gender-specific information about CVD risks to women, causing women to underestimate their risk of developing CVD even when risk factors are clearly evident. Furthermore, women are less likely than men to recognise the signs and symptoms of CVD, delay in seeking treatment, and fail to adopt healthy lifestyles, all of which increase the incidence of mortality and morbidity in a disease that is largely preventable.

CONCLUSION

This review highlights the need for health professionals to 'bridge the gap' between perceived and actual risk of CVD in women, and to develop educational programs that specifically target women.

Sociodemographic differences in myocardial infarction risk perceptions among people with coronary heart disease

This study examines sociodemographic differences in myocardial infarction (MI) risk perceptions among people with coronary heart disease (CHD) (N = 3130). Two variables for comparative risk perceptions were computed: (1) own risk compared to that of an average person; and (2) own risk compared to that of an average person with CHD. Comparative optimism in MI risk perceptions was common, particularly among men and those with higher education. CHD severity and psychosocial resources mediated these sociodemographic differences. These results suggest challenges for secondary prevention in CHD, particularly regarding psychosocial interventions for communicating risk information and supporting lifestyle adjustments.

Physician Knowledge Levels and Barriers to Coronary Risk Prevention in Women

BACKGROUND

Few studies have examined whether physician knowledge, attitudes, or practice patterns might contribute to gender disparities in the primary prevention of coronary heart disease (CHD), including among physicians caring for the largest number of reproductive-age women, obstetricians and gynecologists (OB/GYNs). We sought to identify barriers affecting the provision of recommended coronary risk factor therapies in women.

METHODS

We surveyed internists and OB/GYNs who attended Grand Rounds presentations developed for the New York State Women and Heart Disease Physician Education Initiative. This program was designed to improve screening and management of coronary risk factors in women. Attendees were asked to complete a 7-minute questionnaire.

RESULTS

The mean age of the 529 respondents was 40.3 years (standard deviation = 12.3), 75.1% were internists (n=378), and 42.7% (n=226) were women. Physicians correctly responded to 71.5% of the 13 questions assessing knowledge of coronary risk prevention (range, 4-13). Almost one third of internists and half of the OB/GYNs did not know that tobacco use was the leading cause of myocardial infarction in young women. For patients who smoked tobacco, only two thirds of internists and 55.4% of OB/GYNs reported suggesting a quit date (p=.007). After controlling for covariates, physicians who did not perceive time as a barrier were more likely to discuss smoking cessation (odds ratio=1.7 [1.1-2.7]).

CONCLUSIONS

Among the internists and OB/GYNs surveyed, time was perceived as a barrier to implementing risk prevention. These physicians also underestimated the impact of tobacco use as a risk factor for CHD in young women. To lessen gender disparities in CHD prevention, both specialties need time-efficient educational programs that reflect specialty differences.

[Smoking: knowledge, attitudes, habits and degree of dependence of young adults in Salvador]

This study was aimed at evaluating the degree of smoking dependence and to characterize social demographic data, habits and attitudes of young smokers. Answered the questionnairel02 students from Salvador, State of Bahia, of which 11 were smokers. Their mean age and the age in which they first smoked were 18.2 and 13.4 years respectively. Most of them were male, in the first year of senior high school, of brown skin color and had close relatives who smoke. The majority of those young smokers had been advised about the risks of smoking at home and in school, but few had knowledge about the benefits of quitting. Almost half of them had been smoking for more than three years and had started to smoke out of curiosity. More than half of them smoked one cigarette per day, with low levels of nicotine, bought the cigarettes in shops, and wanted and tried to quit smoking, but never succeeded. The degree of dependence was low for most of them. This study offers hints for nurses to act against smoking with young adults.

Patients' perceptions of cholesterol, cardiovascular disease risk, and risk communication strategies

PURPOSE

Despite some recent improvement in knowledge about cholesterol in the United States, patient adherence to cholesterol treatment recommendations remains suboptimal. We undertook a qualitative study that explored patients' perceptions of cholesterol and cardiovascular disease (CVD) risk and their reactions to 3 strategies for communicating CVD risk.

METHODS

We conducted 7 focus groups in New England using open-ended questions and visual risk communication prompts. The multidisciplinary study team performed qualitative content analysis through immersion/crystallization processes and analyzing coded reports using NVivo qualitative coding software.

RESULTS

All participants were aware that "high cholesterol" levels adversely affect health. Many had, however, inadequate knowledge about hypercholesterolemia and CVD risk, and few knew their cholesterol numbers. Many assumed they had been tested and their cholesterol concentrations were healthy, even if their physicians had not mentioned it. Standard visual representations showing statistical probabilities of risk were assessed as confusing and uninspiring. A strategy that provides a cardiovascular risk-adjusted age was evaluated as clear, memorable, relevant, and potentially capable of motivating people to make healthful changes. A few participants in each focus group were concerned that a cardiovascular risk-adjusted age that was greater than chronological age would frighten patients.

CONCLUSIONS

Complex explanations about cholesterol and CVD risk appear to be insufficient for motivating behavior change. A cardiovascular risk-adjusted age calculator is one strategy that may engage patients in recognizing their CVD risk and, when accompanied by information about risk reduction, may be helpful in communicating risk to patients.

Knowledge of heart attack symptoms in older men and women at risk for acute myocardial infarction

PURPOSE

Coronary heart disease is the number one cause of death for both men and women. While adults 65 years of age and older comprise the largest percentage of those who experience an acute myocardial infarction (AMI), investigators to date have failed to examine the knowledge of this population about AMI symptoms. The purpose of this study was to document knowledge about cardiovascular disease and AMI symptoms in older individuals with coronary heart disease to identify the characteristics associated with increased knowledge of cardiovascular disease.

METHODS

A descriptive design was used with a convenience sample of (N = 115) older adults at risk for AMI. Data were collected during face-to-face interviews in the participants' homes and analyzed using frequencies, percentages, chi, and multiple regression analysis.

RESULTS

Men and women were not significantly different in their knowledge of AMI symptoms except for jaw pain. More than 95% of the both men and women knew typical symptoms of AMI, such as chest pain, pressure, shortness of breath, arm or shoulder pain, and sweating. Less than 75% of both men and women knew that symptoms such as neck pain, nausea or vomiting, back pain, heartburn, and jaw pain could be symptoms of AMI. Thirty-one percent did not know about reperfusion therapies in the treatment of AMI. Having a cardiologist involved in care was weakly predictive of less knowledge.

CONCLUSIONS

Education and counseling of older patients at high risk for heart disease is complex, but should emphasize atypical symptoms and treatment options.

Awareness of heart attack symptoms and lifesaving actions among New York City area residents

The American Heart Association has a national network of community-based programs designed to reduce response times to cardiac emergencies by improving access to automatic external defibrillators (AEDs) among laypersons. Success of these Operation Heartbeat programs depends in part on the public's knowledge of the warning signs of a myocardial infarction (MI) and appropriate response to cardiac arrest victims. In May 2000, a 7-minute telephone survey was administered to a random sample of adults residing within the American Heart Association affiliate territories of New York, New Jersey, and Connecticut to determine the knowledge of MI symptoms, confidence in cardiopulmonary resuscitation (CPR) use, and the awareness of AEDs. Of the respondents, 60% were women (n=1,128), 83% were Caucasians (n=1,558), 15.2% were non-whites (African American, Asian, or Hispanic), and 38.5% had at least a college degree (n=724). Women were significantly more likely than men to know that sex differences exist in the warning signs for an MI (63% vs. 30.7%, respectively; P< .001). Whites had above-average confidence in MI recognition compared with non-whites (39.2% vs. 27.4%, respectively; P< .001) and were more cognizant of the public availability of AEDs (54.5% vs. 33.2%, respectively; P< .001). Our findings suggest that racial/ethnic and sex disparities exist in the awareness of AEDs and in the knowledge of atypical MI symptoms in women, respectively. Innovative CPR outreach programs might be needed in New York area communities to increase CPR training among all adults, to increase AED awareness in vulnerable populations, and to improve knowledge and confidence in the recognition of acute MI symptoms.

Illness perceptions in coronary heart disease. Sociodemographic, illness-related, and psychosocial correlates

OBJECTIVES

This study examined illness perceptions (IP) and their correlates in coronary heart disease (CHD).

METHODS

The sample of the questionnaire study (n = 3130 at baseline and n = 2745 at 1-year follow-up, aged 45-74 years) was drawn from the drug reimbursement register, which covers persons with various drug-treated conditions. Independent variables were CHD severity and history, vicarious experiences, and psychosocial resources.

RESULTS

Men attributed their CHD more often to risk behaviours and internal factors (own attitude/behaviour), while women perceived stress as the cause of their CHD more often. Women also perceived more symptoms associated with CHD but reported less severe consequences. CHD severity was the most important correlate of IP and also predicted change in IP at the follow-up. Stronger perceived competence was related to weaker illness identity, stronger control/cure, and less severe consequences.

CONCLUSIONS

Although disease-related factors are powerful correlates of CHD-related illness cognitions, also social and psychosocial factors are related to IP.

Gender differences in reasons patients delay in seeking treatment for acute myocardial infarction symptoms

Patients (n = 194) with confirmed acute myocardial infarction (AMI) were interviewed to determine sociodemographic, clinical, social, behavioral, cognitive and emotional factors that contribute to delay in seeking treatment for their symptoms. Initial symptom experience was similar for men and women: both were most commonly at home when symptoms began; both were most commonly in the presence of their spouse or other family member; few patients (<10%) called the emergency medical system as their first reaction. Several factors contributed similarly to delay in men and women. Factors that exerted a differential effect on delay between men and women were age, history of AMI, type of AMI (Q-wave and non-Q-wave), concerns about not wanting to trouble others, and prior knowledge of thrombolytics. There was no difference in delay between men and women (median 3.08 versus 3.10 h), but there are important gender differences in the reasons patients delay and in their patterns of decision-making that may assist clinicians trying to tailor interventions.

Do older adults use the Internet for information on heart attacks? Results from a survey of seniors in King County, Washington

BACKGROUND

Early treatment can reduce mortality from heart attacks. However, patient delay, especially among the elderly, has slowed progress in this area. One of the reasons for delay may be because of a lack of knowledge about symptoms of acute myocardial infarction (AMI) and treatment benefits. The Internet is a new and promising source of heart health information, but we know little about how elderly people use this medium.

METHODS

This study investigates the demographic and psychosocial variables that are related to Internet access, health information seeking, and information seeking about heart attacks from the Internet among seniors. We interviewed seniors (N = 323) aged more than 65 years and asked them questions about Internet access, health information seeking, and information seeking on heart attacks, as well as demographic information, risk perceptions for AMI, and personal experience with AMI.

RESULTS

The results showed that several demographic variables were related to access to the Internet. Only 7% of the seniors who reported access to the Internet had sought information on heart attacks from the Internet. Age, history of AMI, and family history of AMI were significant predictors of information seeking on heart attacks. This suggests that to date only a very small, high-risk group of seniors actually seeks information on heart attack emergencies from the Internet.

American adults' knowledge of exercise recommendations

Physical inactivity is a major risk factor for cardiovascular disease, stroke, hypertension, diabetes, obesity, osteoporosis, and some cancers. Approximately 950,000 Americans die annually from cardiovascular diseases. The purpose of this study was to determine whether American adults know which traditional and lifestyle physical activities affect health and how they should be physically active to achieve a health benefit. Secondary purposes were to determine whether this knowledge is a function of gender, ethnicity, education, or age and if those who are sufficiently active for a health benefit possess different knowledge levels than those not sufficiently active for a health benefit. Items based on the Centers for Disease Control and Prevention/American College of Sports Medicine principles included knowledge of exercise guidelines and traditional and lifestyle physical activities. This information was obtained from 20 questions that were part of a national random telephone survey of 2,002 American households in the 48 contiguous states and the District of Columbia. Respondents were most aware of traditional physical activities (M = 94%) that provide a health benefit and less aware of specific exercise guidelines (M = 68%) and lifestyle physical activities (M = 71%) that can result in a health benefit. Knowledge was not related to physical activity behavior sufficient for a health benefit and only slightly related to ethnicity, education, and age. These data suggest that physical activity knowledge alone is not sufficient to elicit a behavior; however, it provides educators with an understanding of the public's physical activity knowledge that could be helpful in developing health promotion and physical activity interventions.

Perceived risk of heart attack: a function of gender?

TOPIC

The influence of gender on women's risk beliefs for heart attack.

PURPOSE

To inform healthcare providers how women's beliefs and attitudes contribute to treatment-seeking delay in the event of a heart attack, and to establish the importance of risk beliefs in women.

SOURCES

Published literature in MEDLINE and CINAHL computerized databases, reference lists of obtained articles.

CONCLUSIONS

Women's perceived risk beliefs for heart attack are influenced by the effects of media, cultural, and gender roles and the modeling of bias in health care. There is a need for healthcare providers to change their focus from acting on (etic) a patient to interacting within (emic) the belief systems of their patients to optimize positive outcomes.

Current Research Promises and Challenges in Behavioral Oncology

The Behavioral Oncology Interest Group of the American Society of Preventive Oncology held a Roundtable session on March 10, 2002, at the American Society of Preventive Oncology annual meeting in Bethesda, Maryland, to discuss the current state-of-the-science in behavioral approaches to cancer prevention and control and to delineate priorities for additional research. Four key areas were considered: (a) behavioral approaches to cancer genetic risk assessment and testing; (b) biological mechanisms of psychosocial effects on cancer; (c) the role of risk perceptions in cancer screening adherence; and (d) the impact of tailored and targeted interventions on cancer prevention and control research. The evidence reviewed indicates that behavioral approaches have made significant contributions to cancer prevention and control research. At the same time, there is a need to more closely link future investigations to the underlying base of behavioral science principles and paradigms that guide them. To successfully bridge the gap between the availability of effective new cancer prevention and control technologies and the participants they are meant to serve will require the development of more integrative conceptual models, the incorporation of more rigorous methodological designs, and more precise identification of the individual and group characteristics of the groups under study.

Physician adherence to preventive cardiology guidelines for women

Despite the publication of the American Heart Association/American College of Cardiology (AHA/ACC) "Guide to Preventive Cardiology for Women" primary care screening and treatment of women at risk for coronary heart disease risk is not optimal. The purpose of this article is to apply a framework of physician behavior to describe specific challenges in implementing clinical practice guidelines for women's cardiovascular health in the primary care setting. Specifically, we illustrate 1) underlying barriers to adherence, 2) attempts and interventions to overcome these barriers, and 3) future areas of research to improve physician adherence to guidelines for the prevention and treatment of heart disease in women.

Perceptions of symptoms of myocardial infarction related to health care seeking behaviors in the elderly

Research on acute myocardial infarction (AMI) suggests that older persons may delay significantly longer than younger persons between the first appearance of symptoms of AMI and seeking treatment and that this delay is associated with increased morbidity and mortality. The factors that potentially influence delay in older persons can be grouped into 4 categories: (a) symptom attribution to aging, (b) symptom severity and duration, (c) symptom attribution to comorbid and chronic conditions, and (d) previous experience with cardiac problems. This article explores the link between symptom interpretation and health care seeking behaviors in elderly patients with AMI as it relates to delay in seeking treatment for AMI. Potential nursing interventions are presented.

Perceived and objective risk in children of patients with peripheral arterial disease

This study examined perceived and objective health risks, health promotive behavior, risk perception, and knowledge of risk factors for peripheral arterial disease (PAD) in children of patients with PAD. Children of patients who had lower extremity distal arterial reconstructive surgery or amputation for complications of PAD completed an investigator-developed questionnaire. Risk factor and behavioral measures were self-reported. Data were collected by telephone interview. The sample consisted of 15 children of 6 patients. Subjects displayed optimistic bias regarding their risk for developing PAD, with 67% reporting their parent's illness had no impact on their health behaviors. Fifty-three percent felt their comparative risk was "about the same" as same-age, same-sex peers. Risk factor knowledge varied and none mentioned hypertension, age, obesity, or gender; the most commonly cited risk factor was diabetes mellitus. Forty-seven percent of the offspring never smoked, less than half exercised regularly, most were overweight or had class I or class II obesity, and most were unaware of their blood pressure or cholesterol levels. Despite frequent interactions with their affected parent, these children exhibited poor understanding of risk factors and personal risk of developing PAD and most did not participate in health promotive behaviors. Educational efforts by national societies promoting an understanding of modifiable risk factors must be improved. Future studies need to explore interventions designed to improve risk perception and health promotive behaviors.

Heart disease risk perception in college men and women

The authors sought to assess the perception of risks for coronary heart disease (CHD) in college men and women. They surveyed 470 undergraduates from 2 major 4-year institutions who completed a questionnaire that measured perceived risks for heart disease. Sixty-eight percent of the respondents rated their risks as lower or much lower than those of their peers, indicating a clear optimistic bias. The research also revealed that the students who exercised regularly rated their risk of coronary disease lower than those who did not do so. In addition, women perceived a number of risk markers to be more potent or causative factors than men did. A significant number of participants did not comprehend commonly understood causal relationships associated with heart disease risk. The findings in this preliminary investigation suggest that college men and women do not accurately perceive their risks for developing heart disease.

The general public's concerns about clinical risk in live kidney donation

Difficulty in attracting live kidney donors may be related to fears regarding both the surgical procedure for kidney harvesting and future failure of the remaining kidney. We conducted a cross-sectional study of households in Maryland to identify public disincentives to living related kidney donation. In multivariate analyses, we assessed the independent effects of several factors on willingness to donate a kidney to a sibling. We also assessed thresholds for factors above which persons would not donate a kidney. Of 385 participants, 66% were extremely willing to donate to a sibling. After adjustment, those who considered the length of a hospital stay, out-of-pocket expenses, size and appearance of a scar, the time it takes to get to the transplant center, and the donor risk of developing kidney failure very important had 50-60% less odds of being extremely willing to donate. Median acceptable levels for risk of complications, hospital stay, compensated and uncompensated time from work, time requiring pain medications, and out-of-pocket expenses were greater than levels from clinical evidence regarding both laparoscopic and open nephrectomy. Unrealistic concerns among the general public regarding live donation may serve as potential disincentives to donation. Efforts to educate the public regarding live donation might help assuage fears and attract those who may not otherwise donate.
