Self-efficacy regarding physical activity is superior to self-assessed activity level, in long-term prediction of cardiovascular events in middle-aged men

Web-Based Nursing Intervention to Promote Physical Activity Among Older Adults After Coronary Revascularization: Protocol for Mixed Method Pilot Study

BACKGROUND

Given the high prevalence of coronary heart disease among older adults and aging populations, there is a need for secondary prevention interventions to help older adults become more physically active. Web-based interventions could be considered for this purpose, knowing that internet use is growing rapidly among older adults. In addition, since older adults would appreciate developing a trusting relationship with a nurse, web-based interventions should include this support, which is not widely observed in the literature.

OBJECTIVE

This study aims to evaluate a web-based nursing intervention aimed at promoting physical activity in people 65 years and older with coronary heart disease.

METHODS

A web-based nursing intervention was developed according to the Intervention Mapping framework in collaboration with a team of health care professionals (n=5) and based on the needs of older adults (n=10). The 7-week intervention (1 session per week) aims to support older adults living with coronary artery disease in resuming, maintaining, or increasing their level of physical activity after coronary bypass surgery or percutaneous coronary intervention. The intervention offers educational content on coronary heart disease and physical activity, suggestions for physical activity, reflective activities, case histories of older adults who have experienced different journeys, an electronic physical activity diary to track progress, and support from a nurse through feedback to increase knowledge, motivation, and sense of self-efficacy. The preliminary effects and impacts of the intervention will be assessed through a mixed method pilot study with a sequential explanatory design. First, a single-group pre-post test will be used to assess the intervention's preliminary effects on physical activity (electronic journal), quality of life (36-Item Short Form Health Survey version 2), knowledge (quiz), motivation, and self-efficacy (visual analog scale) of 30 older adults living with coronary heart disease, as well as the feasibility of the intervention. Second, a descriptive qualitative design will use semistructured interviews to assess the intervention's impacts as perceived by 8-12 older adults and its acceptability. Quantitative data on the effects of the intervention will be integrated with the collection and analysis of qualitative data to assess the impact perceived by older adults, using matrices. Nonparametric statistics and a thematic analysis will be produced. A joint display will be used to integrate mixed data.

RESULTS

The results of this study will provide insight into the preliminary evaluation of a web-based nursing intervention to support older adults living with coronary heart disease as they increase their physical activity levels. The recruitment commenced in June 2024, and data collection should be completed by June 2025.

CONCLUSIONS

With the potential to promote older adults' health, this study could guide the development of new interventions to meet the needs of an aging population.

Examining the Relationship Among Social Cognitive Theory-Based Constructs, Physical Activity, and Blood Pressure in Young- and Middle-Aged Adults Living With Hypertension

BACKGROUND

Psychosocial factors significantly influence lifestyle changes in adults with hypertension. However, research focusing specifically on these factors in young- and middle-aged adults-especially those newly diagnosed within the first 5 years-is limited.

PURPOSE

This cross-sectional study aimed to examine the relationship between psychosocial factors guided by Social Cognitive Theory (perceived stress, self-efficacy, outcome expectancy, and functional and workplace support), physical activity, and blood pressure in young- and middle-aged Thai adults with hypertension.

METHODS

The analysis encompassed 400 adults with hypertension (Mage = 47.98 years; SD = 7.66), with nearly 60% being female from 25 primary care settings in a Thai province. Confirmatory factor analysis validated latent variables, followed by structural equation modeling with maximum likelihood and robust standard errors to analyze direct and indirect effects on physical activity and blood pressure.

RESULTS

Findings highlight self-efficacy in physical activity as a significant predictor of moderate-to-vigorous physical activity, while functional support correlated with reduced systolic blood pressure. Moderate-to-vigorous physical activity mediated the relationship between self-efficacy or functional support and systolic blood pressure. Hypertension duration (diagnosis ≤12 months vs >12 months) moderated the relationship between moderate-to-vigorous physical activity or functional support and diastolic blood pressure.

CONCLUSIONS

Our research presents a new, theory-driven perspective on how psychosocial factors could affect blood pressure levels through physical activity among younger adults newly diagnosed with hypertension. Nurses can leverage this insight by providing education to enhance confidence and engage patients' social networks in supporting their participation in physical activity, thereby improving blood pressure management.

Exploring the Role of Self-Efficacy in Maintaining Healthy Lifestyle Habits among Patients with Cardiometabolic Diseases; Findings from the Multi-Center IACT Cross-Sectional Study

(1) Background: Cardiometabolic disease progression can be delayed if patients engage in healthy lifestyle behaviors, adherence to which is highly influenced by psychosocial factors. The present study aimed at investigating the association of self-efficacy with the adherence level to healthy lifestyle behaviors among patients with cardiometabolic diseases in Greece. (2) Methods: 1988 patients (1180 females) with cardiometabolic diseases participated. Anthropometric, demographic, socioeconomic, clinical, and lifestyle characteristics were recorded. Patients were also asked to evaluate their efficacy to comply with healthy lifestyle behaviors. (3) Results: The majority exhibited unhealthy lifestyle behaviors. A subgroup demonstrated elevated self-efficacy in maintaining healthy habits despite facing diverse psychosocial challenges. Individuals with higher educational attainment, socioeconomic status, and rural/semi-urban residency had significantly elevated self-efficacy. Those with heightened self-efficacy exhibited significantly lower BMI and reduced prevalence of certain health conditions. Self-efficacy significantly influenced adherence to the Mediterranean diet, physical activity engagement, and smoking cessation, even in challenging circumstances. (4) Conclusions: This study represented an innovative approach in examining the role of self-efficacy in shaping health behaviors and outcomes within a Greek population. By integrating specific psychosocial circumstances into the analysis, valuable insights were provided into the contextual factors influencing self-efficacy and adherence to healthy lifestyle behaviors.

The Relationship Between Self-Efficacy and Functional Capacity Among Discharged Heart Failure Patients in Jordan

BACKGROUND

Self-efficacy is an important factor associated with healthy lifestyle changes in heart failure treatment. Functional capacity testing of heart failure patients (HFPs) can stratify prognosis. Reduced functional capacities in HFPs are linked to a poor heart failure prognosis. Limited research has examined the potential relationship between self-efficacy and functional capacity.

AIM

The aims of this study were to assess self-efficacy level and functional capacity among HFPs after hospitalization, and examine whether there is a relationship between them.

METHODS

A descriptive correlational design was used. A convenience sample of 220 HFPs was recruited from 2 hospitals in Jordan. The Arabic version of Cardiac Self-Efficacy Questionnaire was used to assess self-efficacy, the 6-Minute Walking Test (6-MWT) was used to assess functional capacity, and the Borg rating of perceived exertion scale (Borg Scale) was used to assess exertion during 6-MWT.

RESULT

The sample included 46.8% male (n = 103) and 53.2% female (n = 117). The mean age was 52.66 ± 8.91 years. Most of the HFPs were categorized based on New York Heart Association classification as class I, 35.9% (n = 79), and class II, 41.4% (n = 91). The mean ejection fraction was 41.46 ± 9.44. The global self-efficacy was moderate (32.98 ± 9.92), and the mean score for the 6-MWT was 494.35 ± 143.37. The Borg Scale mean was 10.94 ± 3.34. In addition, there was a positive relationship between self-efficacy and 6-MWT (r = 0.63, n = 220, P = .01).

CONCLUSION

This study provides baseline data for further research on treatment of HFPs, and the development of evidence-based tailored health interventions to maintain and improve self-efficacy and functional capacity among these service users. Moreover, replicated researches can test the study results considering different methodologies, such as using objective functional capacity tool and longer follow-up periods.

Adherence and potential factors of adherence to a resistance, coordination and endurance training in older retirement home residents over 6 months

INTRODUCTION

High exercise adherence is a key factor for effective exercise programmes. However, little is known about predictors of exercise adherence to a multimodal machine-based training in older retirement home residents.

AIMS

To assess exercise adherence and potential predictors of adherence. Furthermore, to evaluate user acceptance of the multimodal training and the change in exercise self-efficacy.

METHODS

In this sub-analysis of the bestform-F study, a total of 77 retirement home residents ≥65 years (mean age: 85.6 ± 6.6 years, 77.9% female) participated in a 6-month machine-based resistance, coordination and endurance training. Attendance to the training was documented for each training session. To identify potential predictors a multiple linear regression model was fitted to the data. Analyzed predictors included age, sex, body mass index (BMI), physical function, exercise self-efficacy, and physical activity history. Different domains of user acceptance (e.g. safety aspects, infrastructure) and exercise self-efficacy were assessed by a questionnaire and the exercise self-efficacy scale (ESES), respectively.

RESULTS

Mean exercise adherence was 67.2% (median: 74.4%). The regression model (R2  = 0.225, p = 0.033) revealed that the 6-minute walk test (6-MWT) at baseline significantly predicted exercise adherence (β: 0.074, 95% confidence interval (CI): 0.006-0.142, p = 0.033). Different user domains were rated at least as good by 83.9%-96.9% of participants, reflecting high acceptance. No statistically significant change was found for exercise self-efficacy over 6 months (mean change: 0.47 ± 3.08 points, p = 0.156).

CONCLUSION

Retirement home residents attended more than two thirds of offered training sessions and physical function at baseline was the key factor for predicting adherence. User acceptance of the training devices was highly rated. These findings indicate good potential for implementation of the exercise programme.

A Pilot Study on the Impact of the BumptUp® Mobile App on Physical Activity during and after Pregnancy

To combat maternal morbidity and mortality, interventions designed to increase physical activity levels during and after pregnancy are needed. Mobile phone-based interventions show considerable promise, and BumptUp® has been carefully developed to address the lack of exercise among pregnant and postpartum women. The primary goal of this pilot study was to test the potential efficacy of BumptUp® for improving physical activity among pregnant and postpartum women. A randomized controlled clinical trial was performed (N = 35) with women either receiving access to the mhealth app or an educational brochure. Physical activity and self-efficacy for exercise data were collected at baseline (in mid-pregnancy) and at three additional timepoints (late pregnancy, 6 and 12 weeks postpartum). For moderate-to-vigorous physical activity, a clear trend is observed as the mean estimated difference between groups increases from -0.35 (SE: 1.75) in mid-pregnancy to -0.81 (SE: 1.75) in late pregnancy. For self-efficacy for exercise, the estimated difference of means (control-intervention) changed from 0.96 (SE: 6.53) at baseline to -7.64 (SE: 6.66) in late pregnancy and remained at -6.41 (SE: 6.79) and -6.70 (SE: 6.96) at 6 and 12 weeks postpartum, respectively. When assessing the change in self-efficacy from mid-to -ate pregnancy only, there was a statistically significant difference between groups (p = 0.044). BumptUp® (version 1.0 (3)) shows potential for efficacy. Pilot data suggest key refinements to be made and a larger clinical trial is warranted.

Are home-based exercises effective to reduce blood pressure in hypertensive adults? A systematic review

Sedentarism and chronic non-communicable diseases have been a worldwide health problem that is drastically exacerbated by the COVID-19 pandemic social impacts. Home-based exercises are widely encouraged during social isolation to counterbalance the physical inactive impacts. Although, in the context of hypertension, are home-based exercises effective in blood pressure controlling? Our objective is to conduct a systematic review of high-quality controlled trials comparing the possible effects of different types of home-based exercises in hypertensive patients. The literature search was carried out in three scientific databases: Medline, Europe PMC, and Lilacs. Articles were included following three criteria: analyzing the effect of home-based exercise programs on blood pressure in treated and untreated hypertensive patients; exercises must perform at home and on the frequency, intensity, time, and type (FITT) principle, and the articles were published in English. From the qualitative analysis of 27 original trials screened through 451 identified studies, the main results are the following: 1) both endurance, isometric strength, and respiratory home-based exercise programs were efficient to decrease blood pressure in hypertensive patients; 2) differences in methodological approaches regarding FITT components, distinct blood pressure values at baseline and specific underlying mechanisms must be considered as a potential bias of each home-based interventions. In conclusion, endurance, isometric strength, and breathing home-based programs seems to be effective to reduce blood pressure in hypertensive patients. However, further randomized controlled trials and mechanistic studies must be performing to guide evidence-based recommendations of home-based exercises as antihypertensive therapy.

Sheds for life: health and wellbeing outcomes of a tailored community-based health promotion initiative for men's sheds in Ireland

BACKGROUND

Gender is increasingly recognised as a critical factor in designing community-based health promotion programmes. Men's Sheds ('Sheds') are community-based informal environments that represent a safe space in which to engage cohorts of hard-to-reach (HTR) men in health promotion. Sheds for Life (SFL), the first structured health promotion initiative evaluated globally in Sheds, is a 10-week initiative co-designed with Shed Members (Shedders) and delivered directly in the Shed setting in Ireland. This research describes the health and wellbeing outcomes experienced by SFL participants.

METHODS

Purposive sampling was used to recruit a diverse representation of Shedders (n = 421) participating in SFL alongside a wait list control (n = 86). Questionnaires assessing constructs of health and wellbeing were administered one-to-one in Sheds at baseline, 3, 6 and 12 months. Descriptive data for health outcomes were generated for each time point and assessed for significant changes using inferential testing, while considering COVID-19 impact.

RESULTS

Outcomes related to subjective wellbeing, mental wellbeing, physical activity, social capital and healthy eating significantly increased post SFL (p < 0.05). Mental wellbeing scores (SWEMWBS) post SFL remained significantly higher than baseline despite COVID-19 impact (p < 0.05). Binary logistic regression indicated that the odds of a meaningful SWEMWBS change was significantly higher for shedders that had lower SWEMWBS (OR 0.804), less loneliness (OR 0.638) and lived alone (OR 0.456) at baseline. Shedders with lower SWEMBWS had higher odds of experiencing positive changes in life satisfaction (OR 0.911) and trust (OR 0.928), while Shedders who lived alone had also higher odds of experience positive changes in healthy eating (OR 0.481). Finally, inactive Shedders at baseline had higher odds of experiencing increased levels of physical activity (OR 0.582).

CONCLUSIONS

Findings suggest that the inclusive, community-based SFL model is effective in engaging Shedders and facilitating positive and sustained changes in health and wellbeing outcomes. Using gender-specific approaches in the informal and safe environment of the Shed are effective in engaging men in structured health and wellbeing initiatives, particularly those who may be more vulnerable, isolated or lonely.

Self-report Versus Measured Physical Activity Levels During Outpatient Cardiac Rehabilitation

PURPOSE

Many patients with coronary artery disease (CAD) do not achieve the recommended physical activity (PA) levels during and after cardiac rehabilitation (CR). The aim of this study was to analyze moderate to vigorous physical activity (MVPA) levels and the differences between perceived (self-reported) and measured (activity monitor) MVPA in CAD patients during CR. The second aim was to analyze which patient characteristics were associated with this difference.

METHODS

A two-center observational-sectional study was conducted within the Department of Rehabilitation Medicine of the University Medical Center Groningen between January and April 2018. Adults with CAD, following an outpatient CR program, were included. Perceived MVPA was assessed with the Short Questionnaire to Assess Health-enhancing Physical Activity and compared with ActivPAL3 activity monitor outcomes over a period of 7 d.

RESULTS

Fifty-one patients with CAD (age 59.4 ± 7.1 yr, eight females) were recruited. Four patients (8%) did not achieve the recommended guideline level of ≥150 min/wk of MVPA. Patients spent ≥80% of the week in sedentary activities. Patients overestimated MVPA with a median of 805 (218, 1363) min/wk (P< .001). The selected patient characteristics (age, body mass index, type of CAD, type of CR, social support, and self-efficacy) were not associated with this overestimation.

CONCLUSIONS

Most patients with CAD, participating in an outpatient CR program, do achieve MVPA exercise recommendations but spend simultaneously too much time in sedentary activities.

Association between Social Support and Physical Activity in Patients with Coronary Artery Disease: Multiple Mediating Roles of Self-Efficacy and Autonomous Motivation

Physical inactivity in patients with coronary artery disease is linked to recurrent cardiac events. Given that social support may be an enduring major factor for physical activity, the mechanism underlying the multiple mediating effects of self-efficacy and autonomous motivation on the relationship between social support and physical activity in patients with coronary artery disease has hardly been examined. Therefore, this study aimed to clarify the multiple mediating roles of social support and physical activity on the relationship between self-efficacy and autonomous motivation in patients with coronary artery disease. This descriptive cross-sectional study included 190 inpatients who were diagnosed with coronary artery disease and admitted to a cardiology ward university hospital in Korea. Parallel multiple mediated models were tested using the SPSS PROCESS macro. The direct effects of social support on physical activity and the indirect effects of self-efficacy and autonomous motivation on social support and physical activity were statistically significant. Thus, positive social support from health-care providers has an important role to play in promoting physical activity by increasing self-efficacy and autonomous motivation for physical activity in patients with coronary artery disease.

Adolescent Self-Efficacy for Diet and Exercise Following a School-Based Multicomponent Lifestyle Intervention

Self-efficacy is perhaps the most important parameter associated with behavioral changes. The main aim of this study was to provide insight into the diet and exercise self-efficacy of Greek adolescents and how they could be modified via a multilevel multicomponent school-based lifestyle intervention. Secondary aims were to study the associations of students’ dietary and exercise self-efficacy indices with their anthropometric and sociodemographic parameters. A representative sample of the adolescent population in Attica, consisting of 1610 adolescents aged 12–17 years, recruited from 23 public high schools in three municipalities of the Attica area in Greece, received a three-component lifestyle educational intervention for health promotion and underwent screening for characteristics of metabolic syndrome with the use of portable telemedicine. All assessments and anthropometric measurements were performed at baseline and after the 6-month intervention. Anthropometric measurements included body mass index, waist circumference (WC), waist-to-height ratio (WHtR) and waist-to-hip ratio (WHR). Assessment tools included the Self-efficacy for Diet and the Self-efficacy for Exercise questionnaires, as well as the Mediterranean Diet Quality Index in Children and Adolescents (KIDMED). Analysis included 1020 adolescent students (421 males and 599 females), who completed the self-efficacy questionnaires pre- and post-intervention. Overall, the dietary (p < 0.001) and exercise (p < 0.001) self-efficacy increased significantly post-intervention. Post-intervention, all adolescents decreased their abdominal obesity indices (WC, WHtR, WHR), and this improvement was even more pronounced and significant (p = 0.019, p = 0.019, p = 0.023 respectively) in the adolescents with overweight/obesity. Post-intervention, the proportion of adolescents with normal weight increased from 73.9% to 78.6%, whereas the proportion of adolescents with overweight and obesity decreased from 20.4% to 15.9% and from 5.7% to 5.5%, respectively. Abdominal obesity also decreased from 10.4% to 9.0%. Female adolescents achieved significantly (p = 0.010) higher changes in diet self-efficacy than males. Other sociodemographic characteristics such as family structure, parental age, parental educational level and family income showed non-significant differences. Adolescents with higher KIDMED scores manifested significantly higher dietary and exercise self-efficacy than those with lower KIDMED scores. Both adolescents with normal weight and overweight/obesity manifested a reciprocal relation between diet and exercise self-efficacy. Multicomponent lifestyle interventions in the school environment may provide a first step in students’ behavior changes and provide grounds for future prevention programs in youth.

The importance of domain-specific self-efficacy assessment for substance use and HIV care continuum outcomes among adults in an urban HIV clinic network

Despite the prominence of self-efficacy as a predictor of antiretroviral therapy (ART) adherence, relatively little work has examined domain-specific associations with steps in the care continuum or the possibility that substance use may have domain-specific associations with self-efficacy. This study analyzed data from a sample of 174 people living with HIV recruited through three clinics in the New York City metro area. Consistent with hypotheses, path analysis showed that appointments kept and viral load were each predicted only by their respective domain-specific self-efficacy components (i.e., self-efficacy for keeping appointments, B = 0.01, p = .04; and self-efficacy for taking ART medications, B = -0.02, p < .01). Path models also indicated domain-specific associations with substance use. Self-efficacy for keeping appointments was negatively associated with severity of drug use (B = -1.81, p < .01); meanwhile, self-efficacy for taking ART medications was negatively associated with severity of alcohol use (B = -0.52, p < .01). Accordingly, studies assessing barriers to retention in the HIV care continuum should conduct multi-domain assessments of self-efficacy for differential associations with specific behaviors. Furthermore, HIV care providers might consider screening for domain-specific self-efficacy to identify patients at risk of drop-out and tailoring interventions to various care continuum domains.

Physical Activity and Cardiac Self-Efficacy Levels During Early Recovery After Acute Myocardial Infarction: A Jordanian Study

BACKGROUND

Regular physical activity is important for patients with established coronary heart disease as it favorably influences their coronary risk profile. General self-efficacy is a powerful predictor of health behavior change that involves increases in physical activity levels. Few studies have simultaneously measured physical activity and self-efficacy during early recovery after a first acute myocardial infarction (AMI).

PURPOSE

The aims of this study were to assess changes in objectively measured physical activity levels at 2 weeks (T2) and 6 weeks (T3) and self-reported cardiac self-efficacy at hospital discharge (T1) and at T2 and T3 in patients recovering from AMI.

METHODS

A repeated-measures design was used to recruit a purposive sample of patients from a single center in Jordan who were diagnosed with first AMI and who did not have access to cardiac rehabilitation. A body-worn activity monitor (activPAL) was used to objectively measure free-living physical activity levels for 7 consecutive days at two time points (T2 and T3). An Arabic version of the cardiac self-efficacy scale was administered at T1, T2, and T3. Paired t tests and analysis of variance were used to examine differences in physical activity levels and cardiac self-efficacy scores, respectively.

RESULTS

A sample of 100 participants was recruited, of which 62% were male. The mean age of the sample was 54.5 ± 9.9 years. No statistically significant difference in physical activity levels was measured at 2 weeks (T2) and 6 weeks (T3). Cardiac self-efficacy scores improved significantly between T1, T2, and T3 across subscales and global cardiac self-efficacy.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

Participants recovering from AMI in Jordan did not increase their physical activity levels during the early recovery phase, although cardiac self-efficacy scores improved. This may be because the increase in cardiac self-efficacy was not matched by the practical skills and knowledge required to translate this positive psychological construct into behavioral change. This study provides a first step toward understanding the complex relationship between cardiac self-efficacy and physical activity in this population. The authors hope that these findings support the design of culturally appropriate interventions to increase physical activity levels in this population.

A cross-cultural translation and adaptation of the Arabic Cardiac Self-Efficacy Questionnaire for patients with coronary heart disease

AIM

The aim of this study is to cross-culturally translate and adapt the Cardiac Self-Efficacy Questionnaire into Arabic and subsequently evaluate the psychometric properties of that translation in a population of Arabic patients.

METHOD

The original English version of the Cardiac Self-Efficacy Questionnaire was translated into Arabic following a process recommended by the World Health Organization. A convenience sample consisting of 268 Jordanian patients with coronary heart disease was recruited from a university-affiliated hospital in Amman, Jordan. Data were collected from October 2018 to March 2019. The factor structure, face and content validities, and internal consistency of the Arabic Cardiac Self-Efficacy Questionnaire (A-CSEQ) were evaluated.

RESULTS

The factor structure analysis supported a three-factor high-order structure of the A-CSEQ. Face validity showed that the language used, style, and format were clear. The content validity demonstrated a very good content validity index. The reliability was good with ranging from 0.89 to 0.93 for all questionnaire subscales.

CONCLUSION

The A-CSEQ is a valid and reliable instrument to assess the cardiac self-efficacy of Arabic patients diagnosed with coronary heart disease. Further assessment of the psychometric properties of the A-CSEQ with different cardiac problems is now recommended.

Adaptation and validation of a scale of self-efficacy and social support for physical activity in Spanish patients with severe mental disorders

BACKGROUND

People with severe mental disorders (SMDs) suffer problems of obesity, a sedentary life, and poor physical condition, mainly due to low levels of physical activity. Self-efficacy (SE) and social support (SS) are important components that influence participation in physical activity.

METHODS

This study adapted a scale to assess SE and SS in promoting physical activity in Spanish people with SMDs, as well as provide preliminary evidence of its validity. One hundred Spanish patients (23% female) with SMDs, between 26 and 61 years old, completed the SE/SS assessment for SMD (SE/SS-ASMD).

RESULTS

The instrument seemed to capture a four-factor structure in people with SMDs. Due to the lack of a gold standard, the scale was related to other instruments with which it might be expected to show a correlation, such as those for physical activity and its quality; however, the levels of correlation found were low (≈0.3). The Internal consistency (Cronbach's α) for the SE-ASMD, SS-ASMD staff, SS-ASMD peers, and SS-ASMD family scales were 0.76, 0.76, 0.80, and 0.80, respectively.

CONCLUSIONS

The psychometric analysis of the SE/SS-ASMD supported its suitability as a new tool for researchers in the area of physical activity among people with SMDs.

Survival and incidence of cardiovascular diseases in participants in a long-distance ski race (Vasaloppet, Sweden) compared with the background population

Aims

We studied the relationship between taking part in a long-distance ski race and incidence of cardiovascular diseases (CVDs) to address the hypothesis that lifestyle lowers the incidence.

Methods and results

A cohort of 399 630 subjects in Sweden, half were skiers in the world's largest ski race, and half were non-skiers. Non-skiers were frequency matched for sex, age, and year of race. Individuals with severe diseases were excluded. The endpoints were death, myocardial infarction, or stroke. The subjects were followed up for a maximum of 21.8 years and median of 9.8 years. We identified 9399 death, myocardial infarction, or stroke events among non-skiers and 4784 among the Vasaloppet skiers. The adjusted hazard ratios (HRs) comparing skiers and non-skiers were 0.52 [95% confidence interval (CI) 0.49-0.54] for all-cause mortality, 0.56 (95% CI 0.52-0.60) for myocardial infarction and 0.63 (95% CI 0.58-0.67) for stroke and for all three outcomes 0.56 (95% CI 0.54-0.58). The results were consistent across subgroups: age, sex, family status, education, and race year. For skiers, a doubling of race time was associated with a higher age-adjusted risk of 19%, and male skiers had a doubled risk than female skiers, with a HR 2.06 (95% CI 1.89-2.41). The outcome analyses revealed no differences in risk of atrial fibrillation between skiers and non-skiers.

Conclusion

This large cohort study provides additional support for the hypothesis that individuals with high level of physical activity representing a healthy lifestyle, as evident by their participation in a long-distance ski race, have a lower risk of CVD or death.

Determination of the psychometric properties of the Patients' Self-Efficacy Scale in blood pressure patients

Introduction

This study was designed to determine self-efficacy and its related factors in patients with hypertension.

Materials and methods

This study is descriptive-sectional from the correlation. A total of 250 patients from a blood pressure clinic of Semnan city (in Iran) completed Medication Understanding and Use Self-Efficacy Scale were randomly selected in 2017. Data were analyzed using variance, Pearson’s Correlation, and χ² using the LISREL 8.8 software.

Results

The items 1, 6, 7, and 8 have high correlation (at least higher than 0.60), indicating the possibility of aggregation of these four variables in the first factor (taking medication), and the four items 2, 3, 4, and 5 are highly correlated with each other, which are the second factor (learning about medication). In addition, Cronbach’s α of reliability (taking medication) for the first factor was 0.67 and 0.63 for the second factor (learning about medication) and 0.69 for the whole scale.

Conclusion

The effectiveness of blood pressure self-efficacy is an appropriate tool for measure-taking responsibility for the time and taking medications by patients, and researchers can use it as a valid tool in therapeutic, psychological, and health research.

Heart Failure and Exercise: A Narrative Review of the Role of Self-Efficacy

Chronic heart failure (CHF) is a common, debilitating condition associated with significant health and economic burden. CHF management is multidisciplinary, however, achieving better health relies on a collaborative effort and patient engagement in self-care. Despite the importance of self-care in CHF, many patients have poor adherence to their medical and lifestyle regimens, in particular with regards to engaging in physical exercise. The patient's confidence in their ability, otherwise known as self-efficacy, is an important determinant of CHF health outcomes, most likely due to its effect on the uptake of CHF self-care activities especially exercise initiation and maintenance. Self-efficacy is responsive to experience such as exercise training, however the critical components of exercise interventions to improve self-efficacy have yet to be determined. This narrative review provides an overview of the role of self-efficacy in exercise adherence in CHF.
