Physical activity in primary and secondary prevention of cardiovascular disease: Overview updated

Curcumin supplementation combined with high intensity interval training modulates serum irisin and lipid profile in obese women: "A randomized double-blind clinical trial"

Background

Curcumin is the most widely known active substance of turmeric extract, which attributed numerous functional properties, including anti-inflammatory and cardioprotective properties. Inactivity and changes in lifestyle and subsequent overweight/obesity are becoming major health risk factors.

Objective

the aim of this study was to determine the effect of curcumin supplementation combined with high intensity interval trainings (HIIT) exercise on serum irisin and lipid profile in obese women.

Methods

40 inactive women (aged 30-35 years, and body mass index 30 and above) allocated in four groups (10 in each) as followed; curcumin (C), exercise plus curcumin (EC), placebo (P), and exercise plus placebo (EP). All subjects completed an eight-week HIIT program. The C and EC groups received one capsule containing 80 mg curcumin nanomicelle daily throughout study. Blood samples were taken in the beginning and after eight weeks to measure changes in the study variables (irisin and lipid profile). The ANCOVA and Bonferroni's post hoc test was used to compare variables between 4 groups and pairwise at a significance level of ≤0.05 using SPSS-22.

Results

The results revealed that mean serum irisin (p = 0.023), cholesterol (p = 0.019), triglyceride (p = 0.022), high-density lipoprotein (p = 0.009) and low-density lipoprotein (p = 0.011) were significantly changed in all intervention groups compared to the placebo group.

Conclusion

Based on these results, it can be concluded that HIIT training with curcumin consumption has a greater significancy on obesity reduction in women; Therefore, curcumin and HIIT exercise can be considered as a therapeutic approach to reduce the negative outcomes of obesity.

Clinical trial registry number

IRCT20141004019397N2, link.

Statement of significance

This study investigated the effects of curcumin supplementation combined with high-intensity interval training (HIIT) on human serum Irisin levels for the first time, in a clinical randomized trial. This suggests that HIIT training alongside curcumin consumption may be a promising therapeutic approach to reduce the negative health consequences of obesity in women.

A Confirmatory Factory Analysis of the Exercise Sensitivity Questionnaire (ESQ)

PURPOSE

The Exercise Sensitivity Questionnaire (ESQ) is a self-report measure used to assess the extent to which different physical sensations of exercise elicit anxiety (ie, exercise sensitivity). The ESQ was developed for individuals with cardiovascular conditions and initially validated in a non-clinical sample. This study evaluates the factor structure and measurement invariance in a clinical sample of adults with various cardiovascular conditions.

METHODS

This was a cross-sectional study with retrospective chart review. Patients (N = 265; 73% male, mean age 67.8 ± 10.5 years) were attending an orientation for outpatient medically supervised exercise-based cardiac rehabilitation. The factor structure was examined using Confirmatory Factor Analysis, and tests of measurement invariance were evaluated by sex and advanced age (<65 years, >65 years). Internal consistency, descriptive characteristics, and correlates of ESQ scores and its factors were evaluated. Concurrent validity was evaluated in a subset of patients (N = 57) with elevated exercise sensitivity.

RESULTS

The Confirmatory Factor Analysis supported a 2-factor model, which was invariant, but not a 1-factor model, and reflected anxiety about (1) cardiopulmonary and (2) pain/weakness exercise sensations. Internal consistency of ESQ items was high. ESQ scores were associated with higher body mass index and shorter 6-Minute Walk Test distance, particularly the pain/weakness factor. ESQ scores evidenced preliminary concurrent validity with anxiety sensitivity and general anxiety but discriminant validity with depressive symptoms.

CONCLUSIONS

There is support for the validity and reliability of ESQ scores as a 2-dimensional index of exercise sensitivity. The ESQ taps a psychological phenotype with relevance to exercise tolerance, and potentially cardiac rehabilitation participation, that warrants continued investigation.

Measuring physical activity, automaticity and memory are determinants for physical activity promotion among physical therapists in cardiac and pulmonary rehabilitation: a cross-sectional survey

PURPOSE

The study aims to identify determinants of implementation behavior among physical therapists frequently promoting physical activity (PA) in cardiac and pulmonary rehabilitation.

METHODS

A cross-sectional online survey incorporating the Determinants of Implementation Behavior Questionnaire (DIBQ) and anchored by the Theoretical Domains Framework (TDF) was sent to physical therapists working in cardiac and pulmonary rehabilitation practices in Australia and Singapore. All items on the DIBQ were scored on a 7-point Likert scale from "Strongly Disagree" to "Strongly Agree." Demographics and determinants were associated with frequency of PA promotion using logistic regression analysis with manual backward stepwise elimination. Differences between countries were measured using the Mann-Whitney U test.

RESULTS

Thirty-four Australia and 32 Singapore physical therapists responded to the survey. Seventy-four percent of them correctly identified the PA guidelines and almost all (98%) agreed that PA promotion was the physical therapist's role. However, only 58% encouraged ≥ 10 patients monthly to be physically active. The logistic regression revealed that physical therapists with > 8 years of working experience (AOR = 8.08: 95% CI 1.69-38.67), currently measuring PA (AOR = 8.04: 95% CI 1.73-37.39) and who promote it automatically (Nature of Behaviors) (AOR = 8.57: 95% CI 0.66-111.55) were more likely to frequently promote PA. Similar determinants, except Belief about Consequences, were found between Australia and Singapore physical therapists.

CONCLUSION

Currently measuring PA, automaticity and working experience influence PA promotion frequency among physical therapists working in cardiac and pulmonary rehabilitation, regardless of PA guidelines knowledge, role awareness and countries they practice in.

Validity of Synchronous Online Physical Education Amidst COVID-19 Pandemic

Purpose: Various online physical education activities and methods have been applied to colleges in the Philippines during the COVID-19 confinement. However, much remains unknown about the effects of the physical activity given to students. This study aimed to analyze the validity of online synchronous physical education classes using a progressive cardio workout program among college students. Method: One hundred and ninety-four physical education students enrolled in morning class voluntarily participated. Baseline and posttest measures included resting heart rates, training heart rates, heart rate recovery (HRR), and the YMCA 3-min step test (YMCA 3MST). Results: The progressive cardio workout program over the 8 weeks significantly improved the training heart rate of the participants, X2F(7) = 475.397, p = .001. Also, there is a significant difference between pretest HRR (Mdn = 24) from posttest HRR (Mdn = 16), W = 10,863, p < .001. The pretest HRR was significantly higher than the posttest HRR, the rank–biserial correlation, rB = .586, suggests that this is a large effect size. Further, the pretest YMCA 3MST (Mdn = 120.5) was significantly different from the posttest YMCA 3MST (Mdn = 116), W = 10,946, p < .001, the rank–biserial correlation, rB = .286, suggests that this is a small to medium effect size. Conclusion: This study demonstrated that the 8-week progressive cardio workout program significantly improves the participants’ cardiorespiratory fitness based on the pre- and posttraining heart rate, HRR, and YMCA 3MST results.

The triad of physical activity: An optimal combination for cardiovascular health

The combination of moderate to vigorous physical activity with muscle-strengthening physical activity is increasingly recognized for its significant impact on cardiovascular health. This narrative review synthesizes current evidence to compare the cardiovascular benefits of combined physical activity versus singular forms, especially in primary prevention. The main focus is on hormonal, nervous, genetic, and molecular adaptations, critical mechanisms underlying the body's response to physical activity. Our findings endorse superior benefits for combined moderate to vigorous and muscle-strengthening physical activity for preventing cardiovascular disease (CVD). This combined approach synergistically enhances cardiovascular function and more effectively reduces risk factors than either activity alone. While more research is needed to distinguish between moderate and vigorous activity levels in combination with muscle-strengthening physical activity, current evidence supports comprehensive physical activity guidelines that maximize cardiovascular health. These findings highlight the importance of integrated physical activity regimens in public health strategies and clinical practice to mitigate the global CVD burden.

Objectively-Measured Sedentary Time and Self-Reported Prescription Medication Use Among Adults: A Pilot Study

While previous research has linked physical activity (PA) with lower prescription medication consumption, limited evidence has investigated sedentary time (ST) as a major contributor to medication use, despite ST's known association with chronic disease and mortality risk, even when PA volume is considered. This study aimed to examine the independent associations between objectively measured ST, patterns of sedentary bouts, and self-reported prescription medication use among adults ≥25 years of age. Thirty-two participants reported the number and type of medications they were currently prescribed and wore an accelerometer continuously on their hip for seven days to detect their ST. Poisson regression analysis was used to assess how average daily ST, sedentary bout frequency, and sedentary bout duration influenced medication use. The results revealed a significant association between greater ST and higher medication consumption. Specifically, each additional hour of ST per day, each sedentary bout, and each one-minute increase in bout duration were linked to a 66% (PR 1.66; 95% CI 1.25-2.19; p < 0.001), 36% (PR 1.36; 95% CI 1.12-1.64; p < 0.01), and 9% (PR 1.09; 95% CI 1.03-1.16; p < 0.01) higher prevalence of prescription medications, respectively. These findings suggest that higher ST is associated with a greater prevalence of using prescription medications in adults.

The impact of perception bias for cardiovascular disease risk on physical activity and dietary habits

Objective

Cardiovascular disease (CVD) remains a significant public health challenge in China. Accurate perception of individual CVD risk is crucial for timely intervention and preventive strategies. This study aimed to determine the alignment between CVD risk perception levels and objectively calculated CVD risk levels, then investigate the disparity in physical activity and healthy diet habits among distinct CVD risk perception categories.

Methods

From March to August 2022, a cross-sectional survey was conducted in Zhejiang Province using convenience sampling. Participants aged between 20 and 80 years, without prior diagnosis of CVD were included. CVD risk perception was evaluated with the Chinese version of the Attitude and Beliefs about Cardiovascular Disease Risk Perception Questionnaire, while objective CVD risk was assessed through the Prediction for Atherosclerotic Cardiovascular Disease Risk (China-PAR) model. Participants' demographic information, self-reported physical activity, and healthy diet score were also collected.

Results

A total of 739 participants were included in the final analysis. Less than a third of participants (29.2%) accurately perceived their CVD risk, while 64.5% over-perceived it and 6.2% under-perceived it. Notably, half of the individuals (50.0%) with high CVD risk under-perceived their actual risk. Compared to the accurate perception group, individuals aged 60-80 years old (OR = 6.569), currently drinking (OR = 3.059), and with hypertension (OR = 2.352) were more likely to under-perceive their CVD risk. Meanwhile, participants aged 40-<60 years old (OR = 2.462) and employed (OR = 2.352) were more likely to over-perceive their risk. The proportion of individuals engaging in physical activity was lowest in the under-perception group, although the difference among the three groups was not statistically significant (χ 2 = 2.556, P = 0.278). In addition, the proportion of individuals practicing healthy diet habits was also lowest in the under-perception group, and a significant statistical difference was observed among the three groups (χ 2 = 10.310, P = 0.006).

Conclusion

Only a small proportion of participants accurately perceived their CVD risk, especially among those with high actual CVD risk. Individuals in the under-perceived CVD risk group exhibited the lowest rates of physical activity engagement and healthy diet adherence. Healthcare professionals should prioritize implementing personalized CVD risk communication strategies tailored to specific subgroups to enhance the accuracy of risk perception.

A 10-week multicomponent outdoor exercise program improves hemodynamic parameters and physical fitness in cardiovascular disease adult and elderly patients

This study aimed to assess the effects of a 10-week multicomponent outdoor exercise program on hemodynamic, physical fitness and psychological variables in subjects with CVDs. Twenty participants (12 M and 8 F; age 68.5 ± 8.6 years; BMI 28.49 ± 4.98 kg/m2) suffering from CVDs participated in this randomized controlled study and were allocated into two groups: an experimental group (EG; 6 M, 5 F) who underwent a multicomponent training (i.e., cardiorespiratory, resistance, mobility and breathing exercises; 60’, 2d·wk-1), or a wait-list control group (CG; 6 M, 3 F) who did not engage in any PA. Hemodynamic parameters were assessed through resting heart rate (RHR) and peripheral blood pressure (P-SBP/P-DBP). Physical fitness was assessed via a 30″ chair stand test (30CST), timed up and go (TUG) test, handgrip strength (HGS) test, and 2’ step test (TMST). The health status and quality of life (QoL) were evaluated with short form-12 (SF-12) and World Health Organization QoL (WHOQoL-bref), respectively. After the intervention, EG showed significant reduction in hemodynamic parameters (RHR p < 0.001, ES = 0.98; P-SBP p < 0.001, ES = 0.53; P-DBP: p < 0.001, ES = 0.78), physical fitness (30CST p < 0.001, ES = 0.92; TUG p = 0.001, ES = 0.67; TMST p < 0.05, ES = 0.79) and physical component of SF-12 (PSC-12 p < 0.05, ES = 0.42) compared to CG; no significant changes were observed in HGS, QoL and mental health component of the SF-12 (p > 0.05). The findings showed significant improvements in hemodynamic parameters and physical fitness suggesting the effectiveness of the multicomponent outdoor exercise program in adults and elderly with stabilized CVDs.

Multicomponent versus aerobic exercise intervention: Effects on hemodynamic, physical fitness and quality of life in adult and elderly cardiovascular disease patients: A randomized controlled study

Objective

Cardiovascular diseases (CVDs) remain a leading cause of mortality globally, emphasizing the need for effective preventive measures. This study aimed to investigate the effects of a multicomponent compared to an aerobic training program on the hemodynamic parameters, physical fitness, psychophysical health status and quality of life (QoL) of adults and elderly with stabilized CVDs.

Methods

Thirty-three subjects (19M and 14F; age 69.5 ± 4.9 years; BMI 27.34 ± 4.95 kg/m2) suffering from CVDs voluntarily participated in this 10-week randomized controlled study and were allocated into three groups: multicomponent training group (MTG; 6M, 6F; cardiorespiratory, resistance, flexibility and breathing exercises; 60', 2d·wk-1), aerobic training group (ATG; 7M, 5F; aerobic-only training; 60', 2d·wk-1) or a wait-list control group (CG; 6M, 3F; no PA). Hemodynamic parameters were assessed through resting hearth rate (RHR) and peripheral-systolic and diastolic blood pressure (P-SBP/P-DBP). Physical fitness was assessed via a 30" chair stand test (30CST), timed up and go (TUG) test, handgrip strength (HGS) test, and 2' step test (TMST). The health status, QoL and enjoyment were evaluated with short form-12 (SF-12), world health organization quality of life-bref (WHOQoL-bref) and physical activity enjoyment scale (PACES), respectively.

Results

After the intervention, MTG showed significant improvements in hemodynamic parameters (95 % CI, RHR: 2.76 to 9.07; P-SBP: 3.28 to 13.71; P-DBP: 3.56 to 8.94; p < 0.001), physical fitness (95 % CI, 30CST: 4.42 to -1.90; TUG: 0.56 to 1.58; TMST: 35.24 to -18.58; Dominant HGS: 4.00 to -1.65; Undominant HGS: 2.87 to -0.79, p < 0.001) and enjoyment (PACES: 15.18 to -5.48, p < 0.001) compared to CG; ATG showed significant improvement in hemodynamic parameters (95 % CI, RHR: 1.76 to 8.07; P-SBP: 3.19 to 13.63; P-DBP: 4.47 to 9.85, p < 0.001), physical fitness (95 % CI, 30CST: 2.59 to -0.07; TUG: 0.03 to 1.05; Dominant HGS: 2.42 to -0.07, p < 0.05; TMST: 36.08 to -19.41, p < 0.001) and enjoyment (PACES: 14.68 to -4.98, p < 0.001) compared to CG. No significant changes were observed in QoL and SF-12 (p > 0.05). Significant differences between MTG and ATG were only found in physical fitness variables (95 % CI, 30CST: 3.21 to -0.45, p < 0.01; Dominant HGS: 0.00 to 3.00, p < 0.05).

Conclusions

Findings showed significant improvements in hemodynamic parameters and physical fitness suggesting the effectiveness of the multicomponent exercise program, similar to aerobic-only training, and greater efficacy for lower limb strength and dominant hand grip strength in adults and elderly with stabilized CVDs. Both exercise groups showed similar levels of enjoyment.

Validity of the Active Australia Survey in an Australian cardiac rehabilitation population

OBJECTIVES

To examine the long-term validity of the Active Australia Survey in a cardiac rehabilitation population using accelerometry as the reference measure.

DESIGN

Cohort validation study.

METHODS

Cardiac rehabilitation participants with coronary heart disease were recruited to a prospective cohort study. Over 7-days, 61 participants wore an ActiGraph ActiSleep accelerometer (1-second epoch, 10-minute bout) and completed the self-administered Active Australia Survey at baseline, 6-weeks, 6 and 12-months. Total daily moderate-to-vigorous physical activity from both methods was compared using Bland-Altman plots and Spearman rank-order correlations.

RESULTS

Participants tended to over-report moderate-to-vigorous physical activity, with more active participants more likely to over-report moderate-to-vigorous physical activity. There was a good level of agreement between the accelerometer 1-second epochs and Active Australia Survey at all time points (mean bias (ratio) 1.04, 1.16, 1.14, and 1.06, respectively), with weak-moderate correlations (ρ = 0.3-0.48). Conversely, there was a poor level of agreement between the accelerometer 10-minute bouts and Active Australia Survey at all time points (mean bias (ratio) 6.78, 9.09, 6.35, and 5.68, respectively), with weak-moderate correlations (ρ = 0.3-0.52). Agreement between the two measures did not improve over time for both 1-second and 10-minute bout accelerometry data.

CONCLUSIONS

The Active Australia Survey may be an acceptable self-report measure of moderate-to-vigorous physical activity in cardiac rehabilitation attendees when capturing any time spent in moderate-to-vigorous physical activity. The Active Australia Survey may be useful to routinely monitor physical activity levels over-time in Australian cardiac rehabilitation programs at both individual and group levels.

What stops us and what motivates us? A scoping review and bibliometric analysis of barriers and facilitators to physical activity

INTRODUCTION

Physical inactivity is a major global health concern, contributing to the rising non-communicable disease burden. Elucidating barriers and facilitators influencing participation is critical to promoting activity. This study aimed to synthesize the literature and analyze the extent of research on determinants of physical activity engagement.

METHODS

Scoping review methodology guided the synthesis of 272 publications on factors influencing physical activity. Bibliometric analysis examined publication trends, productivity, influential studies, content themes, and collaboration networks.

RESULTS

Since 2010, the United States has led a significant increase in research output. Highly cited articles identified physiological limitations and psychosocial determinants as key barriers and facilitators. Extensive focus was seen in clinical medicine and exercise science journals. Analysis revealed predominant attention to psychosocial factors, physiological responses, and applications in respiratory disease. Gaps remain regarding policy and environmental factors.

CONCLUSION

This review showed major advances in elucidating determinants while revealing the remaining needs to curb the pandemic of inactivity globally. Expanding international collaboration, contemporary theoretical models, and tailored mixed-methods approaches could promote progress through greater global participation. Addressing knowledge gaps across populations and disciplines should be a priority.

Leisure-time physical activity as a key protective factor against cognitive decline in older adults: an isotemporal substitution analysis

This study aimed to test hypothesized effects of replacing sedentary behavior with moderate-to-vigorous physical activity, sleep, and different domains of physical activity by equivalent amounts on suggestive cognitive decline in an older adult population. This was a cross-sectional study including 473 older adults aged ≥ 60 years. Cognitive decline was assessed using the Mini-Mental Health Examination. Physical activity, its different domains and the time of exposure to sedentary behavior were assessed using the International Physical Activity Questionnaire. For data analysis, two isotemporal substitution models were constructed using Poisson regression. The first model tested the effect of sleep time, sedentary behavior, and moderate-to-vigorous physical activity on cognitive decline. The second model was used to determine the effect of physical activity domains (leisure, work, transport, and home), sleep time, and sedentary behavior on cognitive decline. Physical activity during leisure time was protective against cognitive decline among all domains tested, replacing sedentary behavior, sleep, and transport. Conversely, substitution of the leisure domain for sedentary behavior, sleep, and transport was considered a risk factor for cognitive decline. Leisure time proved to be a strong protective factor in reducing the risk of cognitive decline, and it is necessary to encourage and stimulate public policies that include it.

Effects of intensity, frequency, and time window of exercise on sleep quality among community-dwelling adults aged 65-86 years

BACKGROUND

Although the effects of exercise training (ET) on sleep problem have been reported, the effects according to the components of exercise, including intensity, frequency, and time window, are unknown. Thus, in this study, we aimed to assess the effects of ET on sleep quality in community-dwelling older adults with sleep problems.

METHODS

We evaluated individuals aged ≥65 years whose Pittsburgh sleep quality index was >5 points at baseline. The participants were allocated to either the control group or the ET group and underwent interval walking training (IWT) for 5 months. Information regarding intensity, frequency, and time window of ET were obtained using a waist-worn accelerometer.

RESULTS

Overall, 63 participants (24 men [mean ± standard deviation age: 75.1 ± 4.6 years] and 39 women [74.7 ± 5.2 years]) and 65 participants (24 men [75.2 ± 4.0 years] and 41 women [73.6 ± 4.2 years]) were included in the ET and control groups, respectively. The change in Pittsburgh sleep quality index was not significantly different between the two groups for both sexes. In the ET group, women who exercised 3-8 h before bedtime, men who did ET > 8 h before bedtime and more than 1 h after waking up, and men who did ET ≥ 5.05 days/week experienced significant improvements compared to the baseline.

CONCLUSIONS

IWT does not significantly improve sleep quality. To obtain improvements in sleep quality, it might be necessary to consider the time window of performing ET for both sexes and ET frequency for men.

Workplace health promotion programs: The role of compliance with workers' expectations, the reputation and the productivity of the company

INTRODUCTION

Addressing the health and safety of workers is key to achieving Sustainable Development Goals 3 and 8. The European Union urges companies in its member countries to promote measures in this regard. However, this type of program is not a general approach in European companies. This study aims to identify whether the implementation of Workplace Health Promotion measures is influenced by the company's desire to meet its employees' expectations in this area; and if this relationship involves the company's reputation and productivity.

METHODS

A multi-step methodology is used (descriptive sample portrait, analysis of influences by linear regression, and double-intermediation model analysis) to find out if reputation and productivity mediate the relationship between the satisfaction of employee health expectations and the number of Workplace Health Promotion measures applied.

RESULTS

The more weight the company gives to this compliance, the more motivated it is to implement a more significant number of Workplace Health Promotion measures. The increase in productivity does not seem to weigh in this relationship, but the improvement of the company's reputation does.

CONCLUSIONS

The more the employees' expectations of working in a healthy company are desired to be met, the more measures the company will put in place.

PRACTICAL APPLICATIONS

The findings have theoretical implications, by increasing knowledge about the factors that influence a company's decision to activate Workplace Health Promotion policies. They can also serve as guidance for implementing policies that encourage health promotion in companies and contribute to the achievement of Sustainable Development Goals 3 and 8: for workers' representatives, by better understanding how these factors influence the fulfillment of their constituents' expectations; for company managers, by better knowing the variables involved in this relationship; and for researchers of this topic.

Contribution of youth sport participation to physical activity levels and cardiovascular disease risk factors in 5-year-old to 14-year-old children: a study protocol for systematic review and meta-analysis

INTRODUCTION

Cardiovascular disease (CVD) accounts for 18 million deaths per year, disproportionately burdens under-represented racial and ethnic groups, and has economic costs greater than any other health condition. Participation in youth sport may be an effective strategy to improve CVD-related risk factors but studies of youth sport participation have shown mixed results for improving health outcomes. Therefore, the objective of this systematic review is to examine how participation in youth sport contributes to physical activity levels and CVD risk factors in children aged 5-14 years old. A secondary objective is to determine if outcomes are different in racial and ethnic groups.

METHODS AND ANALYSIS

The search will encompass studies published in English, Spanish or Portuguese between January 1995 and April 2024, including five databases (PubMed, Medline, Embase, Cochrane Library and SPORTDiscus). Studies will be included if they are experimental or observational studies, conducted in youths of any health background and assess the relationship of sport participation to physical activity levels or CVD risk factors. Studies must report on at least one of the following outcomes: (1) physical activity levels, (2) blood pressure, (3) lipid fractions, (4) body mass index (5) central adiposity, (6) systemic inflammation and (7) glucose levels/insulin resistance. Study quality will be assessed using the Cochrane Risk of Bias version 1 tool. Narrative descriptions and summary tables will be created to describe studies, results and methodological quality and be synthesised by subsets of studies based on study design and outcomes. In the systematic review, we will categorise the included studies into two subgroups (ie, observational studies, experimental studies) and meta-analyse them separately prior to exploring sources of heterogeneity.

ETHICS AND DISSEMINATION

Ethical approval is not required. The results will be disseminated via peer-reviewed publication and presentation at conferences relevant to this field.

Association between physical activity changes and incident myocardial infarction after ischemic stroke: a nationwide population-based study

BACKGROUND

The impact of changes in physical activity after ischemic stroke (IS) on the subsequent myocardial infarction (MI) risk is not fully understood. We aimed to investigate the effects of changes in physical activity on the risk of MI after acute IS using data from the Korean National Health Insurance Services Database.

METHODS

224,764 patients newly diagnosed with IS between 2010 and 2016 who underwent two serial biannual health checkups were included. The participants were divided into four categories according to changes in their physical activity: persistent non-exercisers, new exercisers, exercise dropouts, and exercise maintainers. The primary outcome was a new diagnosis of incident MI. Multivariable Cox proportional models were used to assess the effects of changes in exercise habits on the risk of MI.

RESULTS

After a median of 4.25 years of follow-up, 6,611 (2.94%) MI cases were observed. After adjusting for confounders, new exercisers and exercise maintainers were significantly associated with a lower risk of incident MI than persistent non-exercisers (aHR, 0.849; 95% CI, 0.792-0.911; P-value < 0.001; and aHR, 0.746; 95% CI, 0.696-0.801; P-value < 0.001, respectively). Effects were consistent across sexes, more pronounced in those > 65 years. Notably, any level of physical activity after stroke was associated with a reduced MI risk compared to no exercise.

CONCLUSIONS

In this nationwide cohort study, commencing or sustaining physical activity after an IS corresponded to a diminished likelihood of subsequent MI development. Advocating physical activity in ambulatory stroke survivors could potentially attenuate the prospective risk of MI.

Artificial intelligence in preventive cardiology

Artificial intelligence (AI) is a field of study that strives to replicate aspects of human intelligence into machines. Preventive cardiology, a subspeciality of cardiovascular (CV) medicine, aims to target and mitigate known risk factors for CV disease (CVD). AI's integration into preventive cardiology may introduce novel treatment interventions and AI-centered clinician assistive tools to reduce the risk of CVD. AI's role in nutrition, weight loss, physical activity, sleep hygiene, blood pressure, dyslipidemia, smoking, alcohol, recreational drugs, and mental health has been investigated. AI has immense potential to be used for the screening, detection, and monitoring of the mentioned risk factors. However, the current literature must be supplemented with future clinical trials to evaluate the capabilities of AI interventions for preventive cardiology. This review discusses present examples, potentials, and limitations of AI's role for the primary and secondary prevention of CVD.

Physical Activity After Heart Surgery: Associations With Psychosocial and Sleep Factors

BACKGROUND

Heart surgery is an effective intervention for managing heart disease, the leading cause of death globally. After surgery, physical activity is key to improving patients' quality of life and decreasing mortality, but patients are frequently physically inactive after heart surgery.

OBJECTIVE

This cross-sectional pilot study aimed to examine how psychosocial and sleep factors influenced physical activity in patients after heart surgery. The mediating role of sleep factors between psychosocial factors and physical activity was also examined.

METHODS

Thirty-three patients who had undergone heart surgery were recruited. Psychosocial and sleep factors and physical activity were measured using an online survey and a wrist-worn ActiGraph for 7 days and nights.

RESULTS

The participants had heart surgery an average of about 7 years previously. They exceeded the recommended 150 minutes per week of moderate-intensity physical activity for Americans; however, 64% of them showed poor sleep quality (Pittsburgh Sleep Quality Index >5). Higher anxiety and depressive symptoms, lower self-efficacy, and greater sleep disturbances were associated with lower physical activity. Moreover, self-efficacy, sleep duration, sleep disturbance, sleep efficiency, and wake after sleep onset were predictors for physical activity. No mediating role of sleep factors was observed between psychosocial factors and physical activity.

CONCLUSIONS

Psychosocial and sleep factors should be considered when developing and implementing physical activity strategies for patients after heart surgery. Researchers should examine the relationships among the study variables with larger samples of postsurgical cardiac patients during different periods after heart surgery.

Effects of daily sleep on physical activity after cardiac surgery

BACKGROUND

Maintaining physical activity is challenging after cardiac surgery. Postsurgical cardiac patients often experience sleep problems showing a reciprocal interaction with physical activity. As sleep and physical activity show day-to-day variations, their daily relationships need to be assessed. However, no studies have examined daily sleep-physical activity relationships in postsurgical cardiac patients.

OBJECTIVES

This study aimed to examine the effects of daily sleep factors on daily physical activity after cardiac surgery.

METHODS

Among 33 patients who underwent cardiac surgery at least 10 weeks earlier, 5 sleep and 4 physical activity variables were measured using a wrist-worn ActiGraph for 7 days. Mixed-effects models were applied for data analyses.

RESULTS

Most participants were male (57.6 %), non-Hispanic whites (63.6 %) who had coronary artery bypass graft surgery (54.6 %). Participants averaged 60.8 ± 10.1 years of age and 85.7 ± 91.2 months since surgery. They slept for an average of 385.6 ± 74.6 min (6.4 ± 1.2 h). Among sleep factors, greater number of awakenings (NOA) predicted lower next-day sedentary time. Higher sleep efficiency (SE) was associated with lower next-day sedentary time when not controlling for covariates. Among the psychosocial, demographic, and clinical covariates, higher comorbidity index was associated with fewer kcals expended, less daily moderate-to-vigorous physical activity, and more daily sedentary time.

CONCLUSIONS

Daily SE and NOA and individual health status, including comorbidity, should be assessed over time to support improvement of daily physical activity after cardiac surgery. Researchers should examine the relationship between NOA and next-day sedentary time with larger samples. Such research should address multiple psychosocial, demographic, and clinical factors and the potential mediating role of sleep.

Promotion of Physical Activity by Québec Primary Care Physicians: What Has Changed in the Last Decade?

OBJECTIVE

This study aimed to assess the changes in the frequency of physical activity (PA) counseling and in the predictors of primary care PA promotion in Québec primary care physicians (PCPs) between 2010 and 2020.

METHODS

In 2010, we conducted a survey among Québec PCPs. Questions included: frequency of promoting PA to patients, perceived barriers, needs to improve PA promotion practice, frequency of PCPs' PA practice, and sociodemographic information. In 2020, we took over the 2010 questionnaire to document the evolution of the PA promotion practice.

RESULTS

The proportion of PCPs discussing PA with their patients significantly increased (P < .05) in 2020 for the following health conditions: depression, low back pain, chronic obstructive pulmonary disease, and cancer; it declined (P < .05) for overweight patients, those with metabolic syndrome, and in primary prevention. Collaboration with PA professionals was the major need identified, and it increased in 2020. PCPs' own practice of PA was a predictor of PA promotion in 2010 (odds ratio = 6.679; P < .001) and in 2020 (odds ratio = 6.679; P < .001). In both 2010 and in 2020, older or more experienced PCPs were more likely to discuss PA with their patients without diagnosed diseases than younger ones or those with less experience.

CONCLUSIONS

Over the last 10 years, there has been a significant increase in PCPs promoting PA in Québec; however, it has been mainly oriented toward secondary prevention. It is concerning that PA counseling in primary prevention has declined, notably among younger PCPs. The stronger claim for closer collaboration with kinesiologists suggests that PCPs are in favor of an interprofessional strategy, namely collaboration with PA specialists.

Leisure-time and occupational physical activity and risk of cardiovascular disease incidence: a systematic-review and dose-response meta-analysis of prospective cohort studies

BACKGROUND AND OBJECTIVE

Physical activity has benefits for the cardiovascular system, however, what levels and types of activity provide optimal cardiovascular health is unclear. We aimed to determine the level of physical activity that has the most benefits against cardiovascular diseases (CVD).

METHODS

PubMed, Scopus, and Web of Science were searched for prospective cohort studies on leisure-time (LTPA) or occupational physical activity (OPA) as the exposure and major types of CVD (total CVD, coronary heart disease [CHD], stroke, and atrial fibrillation [AF]) incidence as the outcome. Risk of bias of studies was evaluated using the ROBINS-I tool. Summary hazard ratios (HR) were calculated using random-effects pairwise model.

RESULTS

A total of 103 studies were included in the analysis. The highest versus the lowest LTPA was associated with a lower risk of overall CVD (HR = 0.81; 95% CI: 0.77-0.86), CHD (HR = 0.83; 0.79-0.88), and stroke (HR = 0.83; 0.79-0.88), but not AF (HR = 0.98; 0.92-1.05). Linear dose-response analyses showed a 10%, 12%, 9%, and 8% risk reduction in CVD, CHD, stroke, and AF incidence, respectively, for every 20 MET-hours/week increase in LTPA. In nonlinear dose-response analyses, there were inverse associations up to 20 MET-hours/week with 19% and 20% reduction in CVD and CHD risk, and up to 25 MET-hours/week with 22% reduction in stroke, with no further risk reduction at higher LTPA levels. For AF, there was a U-shaped nonlinear association with the maximum 8% risk reduction at 10 MET-hours/week of LTPA. Higher levels of OPA were not associated with risk of CVD, CHD, stroke, or AF.

CONCLUSIONS

Overall, results showed an inverse dose-response relationship between LTPA and risk of CVD, CHD, stroke, and AF. Running was the most beneficial LTPA but the risk was similar among various LTPA intensities. OPA showed no benefits in total or any type of CVD.

Effects of vitamin D, omega-3 and a simple strength exercise programme in cardiovascular disease prevention: The DO-HEALTH randomized controlled trial

BACKGROUND

The effects of non-pharmaceutical interventions in the prevention of cardiovascular diseases (CVD) in older adults remains unclear. Therefore, the aim was to investigate the effect of 2000 IU/day of vitamin D3, omega-3 fatty acids (1 g/day), and a simple home strength exercise program (SHEP) (3×/week) on lipid and CVD biomarkers plasma changes over 3 years, incident hypertension and major cardiovascular events (MACE).

METHODS

The risk of MACE (coronary heart event or intervention, heart failure, stroke) was an exploratory endpoint of DO-HEALTH, incident hypertension and change in biomarkers were secondary endpoints. DO-HEALTH is a completed multicentre, randomised, placebo-controlled, 2 × 2 × 2 factorial design trial enrolling 2157 Europeans aged ≥70 years.

RESULTS

Participants' median age was 74 [72, 77] years, 61.7% were women, 82.5% were at least moderately physically active, and 40.7% had 25(OH)D < 20 ng/mL at baseline. Compared to their controls, omega-3 increased HDL-cholesterol (difference in change over 3 years: 0.08 mmol/L, 95% CI 0.05-0.10), decreased triglycerides (-0.08 mmol/L, (95%CI -0.12 to -0.03), but increased total- (0.15 mmol/L, 95%CI 0.09; 0.2), LDL- (0.11 mmol/L, 0.06; 0.16), and non-HDL-cholesterol (0.07 mmol/L, 95%CI 0.02; 0.12). However, neither omega-3 (adjustedHR 1.00, 95%CI 0.64-1.56), nor vitamin D3 (aHR 1.37, 95%CI 0.88-2.14), nor SHEP (aHR 1.18, 95%CI 0.76-1.84) reduced risk of MACE or incident hypertension compared to control.

CONCLUSION

Among generally healthy, active, and largely vitamin D replete, older adults, treatment with omega-3, vitamin D3, and/or SHEP had no benefit on MACE prevention. Only omega-3 supplementation changed lipid biomarkers, but with mixed effects. TRIAL REGISTRATION CLINICALTRIALS.

Applied Physical Activity Epidemiology: Relationship of Physical Activity and Exercise Exposures with Health Outcomes

There is consistent, strong evidence that both physical activity and exercise lowers risk of many diseases, yet the way physical activity and exercise are measured varies substantially. Physical activity epidemiologists use observational designs (such as cohort or case-control studies) to examine the relationship of physical activity exposures and outcomes including mortality, or disease-specific such as incident type 2 diabetes mellitus, cancer, cardiovascular disease, anxiety, or depression. These same observational designs can be used to examine the associations of prevalent disease in reducing symptom burden in those who are physically active compared to those who are not, specifically examining anxiety and depression. There is great statistical power and often large sample sizes in physical activity epidemiologic studies with valid and reliable assessment tools but known limitations such as measurement error or social desirability bias. Overall, physical activity epidemiology can be a useful tool to understand the influence of exercise and physical activity on risk of disease. In this chapter, we will explore the strength, consistency, and sources of evidence primarily using a physical activity epidemiology lens.

The effectiveness of digital health interventions for the maintenance of physical activity following cardiac rehabilitation: A systematic review and meta-analysis

Objective

To summarise the effectiveness of digital health maintenance interventions for subjectively and objectively measured physical activity level (PA) and physical function, fitness and health-related quality of life (HRQoL) after completion of phase II cardiac rehabilitation (CR).

Methods

We conducted a search for studies in MEDLINE, Embase, CENTRAL, and CINAHL (inception to May 2024). Independent reviewers selected and included randomised controlled trials (RCTs) using digital health interventions to maintain PA in patients with cardiovascular disease after phase II CR. Independent reviewers conducted data extraction, assessed the risk of bias using the Cochrane Risk of Bias 2 tool and rated the certainty of evidence using Grading of Recommendations Assessment, Development and Evaluation - registered at PROSPERO: CRD42023396629.

Results

From 17,455 hits, 20 RCTs with 1801 participants were included. Risk of bias for most studies reporting on PA outcomes was rated as 'some concerns'. Comparing digital health intervention with minimal intervention/usual care showed no effect of objective PA (standardised mean difference (SMD) 0.85, 95% CI: -0.07 to 1.77) and a small effect of subjective PA (SMD 0.37, 95% CI: 0.05 to 0.69) at the end of intervention both graded as very low certainty of evidence. We found very low certainty of evidence for moderate effects on physical function (SMD 0.63, 95% CI: 0.03 to 1.24), and low certainty of evidence for no effect on physical fitness (SMD 0.19, 95% CI: 0.05 to 0.34) and HRQoL (SMD 0.13, 95% CI: -0.02 to 0.28), I 2= 0.00%) at the end of intervention.

Conclusion

Digital health interventions showed a small effect on subjectively measured PA, and no effect on objective PA, physical fitness and HRQoL, but may increase physical function after CR completion. Yet, the certainty of evidence is low and higher quality studies with longer follow-up duration are needed to guide this area further.

If you measure it, it matters!: a survey of factors influencing implementation of physical activity promotion in cardiac and pulmonary rehabilitation in Australia

OBJECTIVE

To identify factors related to the frequency of physical activity (PA) promotion by health professionals working in cardiac and/or pulmonary rehabilitation.

METHODS

A cross-sectional online survey of health professionals working in cardiac and/or pulmonary rehabilitation in Australia was conducted between July and November 2022.

RESULTS

A total of 71 health professionals from four disciplines (physiotherapy, nursing, exercise physiology, occupational therapy) completed the survey. The majority agreed that PA promotion was part of their role. Despite this, only half of the participants encouraged ≥ 10 patients per month to be more physically active. In logistic regression modelling, health professionals that measured patients' PA levels (odds ratio 8.04, 95% confidence level 1.45-44.19) and prioritised PA promotion regardless of other patient problems (odds ratio 3.3, 95% confidence level 0.74-14.82) were much more likely to frequently promote PA to patients.

CONCLUSION

Measurement of patients' PA levels within cardiac and pulmonary rehabilitation and making PA promotion a priority may impact the implementation of PA promotion within these programs.

PRACTICAL IMPLICATIONS

Physical activity measurement as a key performance indicator in cardiac and pulmonary rehabilitation is indicated. This may be an important strategy to increase physical activity promotion by cardiac and pulmonary rehabilitation health professionals.

Very brief intervention for physical activity behaviour change in cardiac rehabilitation: protocol for the 'Measure It!' effectiveness-implementation hybrid trial

INTRODUCTION

Physical inactivity is a risk factor for repeat cardiac events and all-cause mortality in coronary heart disease (CHD). Cardiac rehabilitation, a secondary prevention programme, aims to increase physical activity levels in this population from a reported low baseline. This trial will investigate the effectiveness and implementation of a very brief physical activity intervention, comparing different frequencies of physical activity measurement by cardiac rehabilitation clinicians. The Measure It! intervention (<5 min) includes a self-report and objective measure of physical activity (steps) plus very brief physical activity advice.

METHODS AND ANALYSIS

This type 1 hybrid effectiveness-implementation study will use a two-arm multicentre assessor-blind randomised trial design. Insufficiently active (<150 min of moderate-to-vigorous physical activity per week) cardiac rehabilitation attendees with CHD (18+ years) will be recruited from five phase II cardiac rehabilitation centres (n=190). Patients will be randomised (1:1) to five physical activity measurements or two physical activity measurements in total over 24 weeks. The primary effectiveness outcome is accelerometer daily minutes of moderate-to-vigorous intensity physical activity at 24 weeks. Secondary effectiveness outcomes include body mass index, waist circumference and quality-of-life. An understanding of multilevel contextual factors that influence implementation, and antecedent outcomes to implementation of the intervention (eg, feasibility and acceptability), will be obtained using semistructured interviews and other data sources. Linear mixed-effects models will be used to analyse effectiveness outcomes. Qualitative data will be thematically analysed inductively and deductively using framework analysis, with the framework guided by the Consolidated Framework for Implementation Research and Theoretical Domains Framework.

ETHICS AND DISSEMINATION

The study has ethical approval (University of Canberra (ID 11836), Calvary Bruce Public Hospital (ID 14-2022) and the Greater Western Area (ID 2022/ETH01381) Human Research Ethics Committees). Results will be disseminated in multiple formats for consumer, public and clinical audiences.

Accelerometer Use to Measure Physical Activity in Older Adults With Coronary Artery Disease: An Integrative Review

BACKGROUND

Physical activity is necessary for improved health outcomes among older adults with coronary artery disease (CAD), and device-based assessment of physical activity is preferred for accurate measurement. Many previous studies have applied accelerometry to examine physical activity in this population, but no reviews have systematically examined the application of various accelerometers to measure physical activity in older adults with CAD.

OBJECTIVE

This integrative review aimed to examine accelerometry application to measure physical activity in older adults with CAD and provide guidance for accelerometer selection and settings.

METHODS

Six databases-CINAHL, PubMed, PsycINFO, Scopus, EMBASE, and Google Scholar-were searched for information sources. Authors of selected studies applied accelerometers to measure physical activity and included adults 60 years or older with CAD.

RESULTS

Among 12 studies reviewed, 5 were randomized controlled trials, and most used an age cutoff of 65 years for older adults. The most frequently used accelerometer was the RT3, and the most common device placement was the waist/hip. Data collection duration was typically 3 consecutive days. However, many study authors did not report epoch length, sampling frequency, number of valid hours of data required per day, total number of valid days of data needed, or criteria for nonwear time.

CONCLUSIONS

On the basis of data synthesis and previous study results, triaxial research-grade accelerometers, waist/hip placement, and a 5- to 7-day monitoring period are recommended for measuring physical activity in older adults with CAD. However, the study purpose, device and participant characteristics, and physical activity outcomes of interest should be considered during device selection.

Diabetic Polyneuropathy and Physical Activity in Type 1 Diabetes Mellitus: A Cross-Sectional Study

BACKGROUND

The purpose of this study is to access whether a personal attitude to physical activity (PA) may influence the appearance of diabetic polyneuropathy (DPN) patients with well-controlled type 1 diabetes mellitus.

METHODS

Ninety patients attending the diabetes technology outpatient clinic were enrolled. DPN was investigated according to the Toronto consensus diagnostic criteria. PA was assessed using the International Physical Activity Questionnaire.

RESULTS

PA was low in 21.1%, moderate in 42.2% and high in 36.7% of patients. According to Toronto criteria, we defined two categories: the first one with DPN absent or possible (57 (63.3%)) and a second one with DPN certain or probable (33 (36.7%)). The χ2-test of the PA groups and the DPN categories showed a statistically significant difference (p < 0.001), with less neuropathy in patients belonging to the group of moderate/high PA. Exposure to a minimum of 600 MET minutes/week was protective factor against the onset of DPN (odd ratio 0.221, c.i. 0.068-0.720, p = 0.012).

CONCLUSIONS

This study suggests that DPN is less present in type 1 diabetic patients with good metabolic control and a good personal habit of PA. Moderate-to-vigorous PA of at least 600 MET minutes/week might be a protective factor against DPN.

Factors associated with diet quality among Brazilian individuals with cardiovascular diseases

BACKGROUND

An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors.

METHODS

This is a cross-sectional study carried out with individuals with atherosclerosis (coronary artery disease, cerebrovascular disease or peripheral arterial disease) recruited from 35 reference centres for the treatment of cardiovascular disease in Brazil. Diet quality was assessed according to the Modified Alternative Healthy Eating Index (mAHEI) and stratified into tertiles. For comparing two groups, the Mann-Whitney or Pearson's chi-squared tests were used. However, for comparing three or more groups, analysis of variance or Kruskal-Wallis was used. For the confounding analysis, a multinomial regression model was used. p < 0.05 was considered statistically significant.

RESULTS

In total, 2360 individuals were evaluated: 58.5% male and 64.2% elderly. The median (interquartile range [IQR]) of the mAHEI was 24.0 (20.0-30.0), ranging from 0.4 to 56.0 points. When comparing the odds ratios (ORs) for the low (first tertile) and medium (second tertile) diet quality groups with the high-quality group (third tertile), it was observed that there was an association between diet quality with a family income of 1.885 (95% confidence intervals [CI] = 1.302-2.729) and 1.566 (95% CI = 1.097-2.235), as well as physical activity of 1.391 (95% CI = 1.107-1.749) and 1.346 (95% CI = 1.086-1.667), respectively. In addition, associations were observed between diet quality and region of residence.

CONCLUSIONS

A low-quality diet was associated with family income, sedentarism and geographical area. These data are extremely relevant to assist in coping with cardiovascular disease because they enable an assessment of the distribution of these factors in different regions of the country.

Sedentary Time and Prescription Medication Use Among US Adults: 2017-2018 National Health and Nutrition Examination Survey

BACKGROUND

Prescription medication usage has been used as a predictor of disease prevalence and overall health status. Evidence suggests an inverse relationship exists between polypharmacy, which is the use of 5 or more medications, and physical activity participation. However, there is limited evidence examining the relationship between sedentary time and polypharmacy in adults. The aim of this study was to examine the associations between sedentary time and polypharmacy in a large nationally representative sample of US adults.

METHODS

Study sample (N = 2879) included nonpregnant adult (≥20 y old) participants from the 2017-2018 National Health and Nutrition Examination Survey. Self-reported minutes per day of sedentary time were converted to hours per day. The dependent variable was polypharmacy (≥5 medications).

RESULTS

Analysis revealed that for every hour of sedentary time, there was 4% greater odds of polypharmacy (odds ratio, 1.04; 95% confidence interval, 1.00-1.07, P = .04) after adjusting for age, race/ethnicity, education, waist circumference, and the interaction term between race/ethnicity and education.

CONCLUSION

Our findings suggest increased sedentary time is associated with an increased risk of polypharmacy among a large nationally representative sample of US adults.

Incorporating Exercise Training into Cardio-Oncology Care: Current Evidence and Opportunities: JACC: CardioOncology State-of-the-Art Review

Cancer treatment-induced cardiotoxicities are an ongoing concern throughout the cancer care continuum from treatment initiation to survivorship. Several "standard-of-care" primary, secondary, and tertiary prevention strategies are available to prevent the development or further progression of cancer treatment-induced cardiotoxicities and their risk factors. Despite exercise's established benefits on the cardiovascular system, it has not been widely adopted as a nonpharmacologic cardioprotective strategy within cardio-oncology care. In this state-of-the-art review, the authors discuss cancer treatment-induced cardiotoxicities, review the existing evidence supporting the role of exercise in preventing and managing these sequelae in at-risk and affected individuals living after cancer diagnoses, and propose considerations for implementing exercise-based services in cardio-oncology practice.

A Clinical Guide for Assessment and Prescription of Exercise and Physical Activity in Cardiac Rehabilitation. A CSANZ Position Statement

Patients with cardiovascular disease benefit from cardiac rehabilitation, which includes structured exercise and physical activity as core components. This position statement provides pragmatic, evidence-based guidance for the assessment and prescription of exercise and physical activity for cardiac rehabilitation clinicians, recognising the latest international guidelines, scientific evidence and the increasing use of technology and virtual delivery methods. The patient-centred assessment and prescription of aerobic exercise, resistance exercise and physical activity have been addressed, including progression and safety considerations.

Physical fitness, cardiovascular and musculoskeletal health, and occupational performance in firefighters

Introduction

To perform their work efficiently and safely, firefighters should maintain all aspects of physical fitness. Cardiac-related incidents are the leading cause of duty-related deaths in firefighters, and many firefighters have poor musculoskeletal health (MSH) that hinder their occupational performance (OP). Establishing the relationship between physical fitness, cardiovascular health (CVH), MSH and OP may add new insight on the most significant factors influencing OP in firefighters, specifically in the City of Cape Town Fire and Rescue Service (CoCTFS), which had not been studied before. Therefore, the purpose of this study was to investigate whether physical fitness, CVH and MSH were associated with OP in firefighters, in the COCTFRS.

Methods

This cross-sectional study included 283 full-time firefighters aged 20-65 years from Cape Town, South Africa. A researcher-generated questionnaire was used to collect data on sociodemographic characteristics, lifestyle factors and MSH. Physical measures were used to collect information on physical fitness, CVH, and OP [using a physical ability test (PAT)]. Linear and binary logistic regressions, adjusted for age, sex, height and weekly metabolic equivalent minutes (WMETM), multivariate analysis of covariance (MANCOVA), adjusted for age, sex, height and body mass index (BMI) and backward stepwise regressions were used to investigate the associations between the various constructs.

Results

From multivariable analyses, age, lean body mass, body fat percentage (BF%), estimated absolute oxygen consumption (abV̇O2max), grip strength, leg strength, push-ups, sit-ups, WMETM and heart rate variability were associated with PAT completion times (all p < 0.01). The MANCOVA showed a significant difference between performance categories of the PAT based on physical fitness and CVH (both p < 0.001). WMETM, BF%, abV̇O2max, grip strength, leg strength and sit-ups explained the highest proportion (50.5%) of the variation in PAT completion times.

Conclusion

Younger, non-obese, fitter and stronger firefighters, with a better CVH status, performed significantly better and were most likely to pass the PAT in firefighters, in Cape Town, South Africa. Firefighters should maintain high levels of physical fitness and a good level of CVH to ensure a satisfactory level of OP.

An Exploratory Research to Assess Total Nutritional Knowledge of Students at the University of Lahore, Pakistan

Background: Good nutrition is imperative to achieve a better health status. The rate of obesity and related comorbidities is increasing all over the world. The main reasons behind this worse situation are the overconsumption of food groups or exceeding the recommended portion sizes. University life is a period when students are independent in making their food choices. The chances of adopting unhealthy eating behaviors are increased during this tenure. Nutritional knowledge is an important tool in assessing the nutritional status of an individual, group, and community. Objectives: The main objective of the current study was to assess the nutritional knowledge of university-going students. Methods: The pre-tested questionnaire was used to collect the data from the students of the University of Lahore, Pakistan. A total of 300 students participated in this study (150 from the Nutrition Department and 150 from the non-nutrition departments). Demographic data, anthropometric measurements, and total nutritional knowledge (TNK) scores were measured during the 4-month study duration. Additionally, gender-and department-based comparisons of various parameters were performed. The mean TNK of the Nutrition Department students was higher (34.89 ± 0.95/58) than non-nutrition departments (24.05 ± 1.00/58) (P = 0.01). Additionally, the mean TNK of female students was higher (28.53 ± 1.28/58) than male students (27.05 ± 1.27/58) (P = 0.03). Moreover, 61% and 63% of nutrition students were familiar with the relationship between high intake of salt and fats with chronic diseases, respectively. Results: A statistically significant relationship was not observed between gender (P = 0.78) and departments (P = 0.10) with body mass index (BMI). This finding shows that nutritional knowledge alone is not a predictor of the nutritional status (BMI) of an individual. Students, even from the Nutrition Department, failed to transform their knowledge about nutrition into healthy food choices and eating practices. Conclusions: It is necessary to initiate nutrition education programs emphasizing making healthy food choices. Moreover, nutritional knowledge related to dietary guidelines should be incorporated into daily life to remove the disease burden associated with obesity.

Effects of a Physical Exercise Programme through Service-Learning Methodology on Physical Activity, Physical Fitness and Perception of Physical Fitness and Health in University Students from Spain: A Preliminary Study

The practice of physical activity has been reported on countless occasions for the benefits it has on people's holistic health. However, today's society has high levels of inactivity and sedentary lifestyles, which highlights the importance of promoting active and healthy states in the population. As a mechanism to improve body composition, physical condition and perceived values of one's own physical condition and health status, the implementation of a strength training programme in the university community was proposed using a methodology based on Service-Learning. The participants were 12 students as coaches and 57 students from different university degrees as coachees (17 boys and 40 girls); the ages of the participants ranged from 18 to 33 years (M = 22.00; SD = 2.96). The variables of body composition, physical fitness, physical activity level and perception of fitness and health were assessed. Differences between pre- and post-intervention results were analysed using the Student's t-test and Wilcoxon test for ordinal self-perception variables. The results showed significant improvements in all the variables evaluated after the intervention. In conclusion, we would like to highlight the benefits of physical activity and the need to continue implementing action and intervention plans to encourage and promote its practice in all sectors of the population.

Use of co-design methodology in the development of cardiovascular disease secondary prevention interventions: A scoping review

INTRODUCTION

There is growing evidence to support the use of co-design in developing interventions across many disciplines. This scoping review aims to examine how co-design methodology has been used in the development of cardiovascular disease (CVD) secondary prevention interventions within health and community settings.

METHODS

We searched four academic databases for studies that used the co-design approach to develop their intervention. Studies were included if consumers (adults with CVD) and key stakeholders (e.g. clinicians, service providers) were involved in the co-design process. The review focused on methodology rather than traditional study outcomes; therefore, co-design processes and activities were extracted and evaluated against a selected co-design framework.

RESULTS

Twenty-two studies were included in this review. Studies were implemented across various settings with consumers and stakeholder groups most frequently consisting of patients and healthcare professionals, respectively. Most studies specifically stated that they used a 'co-design' approach (n = 10); others used terms such as participatory action research (n = 3), user-centred design (n = 3) and community-based participatory research (n = 2). Although there was variability in terminology, co-design processes, and participants, all studies adhered to the key principles of consumer engagement. Predominant co-design activities included semistructured interviews, focus groups, co-design/development workshops and advisory group meetings. Intervention effectiveness was assessed in eight studies showing mixed results.

CONCLUSIONS

This review provides an overview of how the co-design approach has previously been used in the development of CVD secondary prevention interventions. These findings provide methodological considerations that can guide researchers and healthcare services when implementing co-design to develop feasible and acceptable interventions that can improve outcomes for CVD populations.

PATIENT OR PUBLIC CONTRIBUTION

No patients, service users, caregivers, people with lived experience or members of the public were involved in this scoping review. This review article was written by academics who have undertaken a significant amount of co-design work with consumers and stakeholders.

High-Intensity Interval Training Minimizes the Deleterious Effects of Arterial Hypertension on the Urinary Bladder of Spontaneously Hypertensive Rats

Arterial hypertension promotes urological complications by modifying the functional capacity of the urinary bladder. On the other hand, physical exercise has been suggested as a nonpharmacological tool to improve blood pressure regulation. High-intensity interval training (HIIT) can effectively increase peak oxygen consumption, body composition, physical fitness, and health-related characteristics of adults; however, its action on the urinary bladder is little discussed. In the present study, we verified the effect of HIIT on the modulation of the redox state, morphology, and inflammatory and apoptotic processes of the urinary bladder of hypertensive rats. Spontaneously hypertensive rats (SHR) were divided into two groups: SHR sedentary and SHR submitted to HIIT. Arterial hypertension promoted an increase in the plasma redox state, modified the volume of the urinary bladder, and increased collagen deposition in detrusor muscle. It was also possible to identify, in the sedentary SHR group, an increase in inflammatory markers such as IL-6 and TNF-α in the urinary bladder, as well as a reduction in BAX expression. However, in the HIIT group, reduced blood pressure levels were observed, together with an improvement in morphology, such as a decrease in collagen deposition. HIIT also regulated the proinflammatory response, promoting increases in IL-10 and BAX expressions and in the number of plasma antioxidant enzymes. The present work highlights the intracellular pathways involved with the oxidative and inflammatory capacity of the urinary bladder and the potential effect of HIIT on the regulation of the urothelium and detrusor muscle of hypertensive rats.

Developing a research agenda on exercise and physical activity for people with limb loss in Canada

PURPOSE

There is a lack of high-quality evidence about the effects of exercise or physical activity interventions for adults with lower limb amputations (LLAs). A planning meeting involving stakeholders (i.e., people with LLA, community advocates, health care providers, researchers) was organized to identify key research priorities related to exercise and physical activity for people with LLAs.

METHODS

We used a collaborative prioritized planning process with a pre-meeting survey and 2-day virtual meeting that included: identification and prioritization of challenges or gaps; identification and consolidation of solutions; and action planning. This process integrated a modified Delphi approach, including anonymous feedback in two surveys.

RESULTS

Thirty-five stakeholders participated. Six challenges related to exercise and physical activity for people with LLA were prioritized. One solution was prioritized for each challenge. After consolidation of solutions, participants developed five research action plans for research including: developing an on-line interface; developing and evaluating peer-support programs to support physical activity; examining integration of people with LLA into cardiac rehabilitation; development and evaluation of health provider education; and determining priority outcomes related to physical activity and exercise.

CONCLUSIONS

This collaborative process resulted in an action plan for amputation research and fostered collaborations to move identified priorities into action.IMPLICATIONS FOR REHABILITATIONLower limb amputations impact mobility leading to lower levels of physical activity.There are research gaps in our understanding of the effects of exercise or physical activity interventions for adults with lower limb amputations.Through a collaborative planning process, participants prioritized research directions on physical activity and exercise for people with LLA to advance research in the field.Action plans for research focused on developing online resources, peer support, cardiac rehabilitation for people with LLA, health provider education and determining priority outcomes related to physical activity and exercise.

Factors affecting the physical activity of healthcare workers of Iran University of Medical Sciences: a qualitative study

Background

Low physical activity in adulthood is a major public health challenge. The majority of adults spend many hours each week at work, and workplace thus becomes a suitable location in which to promote health and implement physical activity programs. This qualitative study was conducted to identify the barriers and facilitators of worksite physical activity from the perspective of the employees of Iran University of Medical Sciences.

Methods

In this qualitative thematic analysis, five focus group discussions were held with the participation of 68 staff members of Iran University of Medical Sciences who had been selected by purposive sampling with maximum diversity.

Results

The analysis of the data led to the identification of three general themes, including challenges and barriers, strategies, and incentives (facilitators). The four main categories of challenges and barriers included policy-making and legislation, organizational factors, structural factors, and personal factors. Most barriers identified by the participants were placed in the personal factors and organizational factors categories. The strategies for increasing physical activity were identified in the following three categories: Policy-making and legislation, organizational factors, and environmental factors. The majority of the strategies proposed were placed in the organizational factors and policy-making and legislation categories.

Conclusions

Increasing physical activity in the workplace as a strategy for the general promotion of physical activity in people requires interventions in different areas, especially with regard to organizational factors and policy-making and legislation.

Effects of Cardiovascular Disease Risk Factors, Musculoskeletal Health, and Physical Fitness on Occupational Performance in Firefighters-A Systematic Review and Meta-Analysis

Background: Firefighting is a strenuous occupation, which necessitates that firefighters stay in good physical condition and maintain adequate cardiovascular and musculoskeletal fitness to perform their duties with minimal health and safety risks. The aim of this review is to determine the effects of cardiovascular disease risk factors, musculoskeletal health, and physical fitness on the occupational performance of firefighters. Methods: PubMed/Medline, SCOPUS, Web of Science, EBSCOHost, and ScienceDirect were searched without time-restriction. The appraisal tool for cross-sectional studies and the Critical Appraisal Skills Programme toolkit were used to conduct the methodological assessment. Data were analyzed using Review Manager 5.3, and MedCalc^® statistical software. Results: Age had a moderate effect on occupational performance (Z = 5.15, p < 0.001), whereas gender had a large effect size on occupational performance (Z = 4.24, p < 0.001). A significant moderate negative correlation was found between cardiorespiratory fitness and occupational performance (R = -0.584, p < 0.001). Significant low negative correlations were found between upper body endurance (R = -0.344, p < 0.001), abdominal endurance (R = -0.308, p < 0.001), grip strength (R = -0.421, p < 0.001), upper body strength (R = -0.318, p < 0.001), and lower body strength (R = -0.216, p = 0.020) and occupational performance. Conclusions: Aged firefighters with poor body composition and lower levels of physical fitness performed worse on all occupational performance tasks.

Determinants of Physical Activity in the Cardiac Population: Protocol for a Systematic Review

BACKGROUND

Lack of physical activity is a critical contributing risk factor to cardiovascular disease. Hence, regular physical activity is a mainstay in the primary and secondary prevention of cardiovascular disease. Despite the extensive promotion of physical activity in both primary and secondary prevention programs, including cardiac rehabilitation, physical activity levels in the cardiac population remain low. Therefore, it is crucial to understand critical determinants that influence physical activity behavior.

OBJECTIVE

This study aims to deliver a systematic review of studies with collated observational data exploring the association between determinants and physical activity behavior in the target population. These new insights inform the design of future interventions targeted at lasting heart-healthy physical activity behavior in the cardiac population.

METHODS

Primary studies with observational quantitative data on determinants and their association with physical activity behavior in the cardiac population will be included. Information on relevant primary studies will be retrieved from various databases, including Embase, CINAHL, MEDLINE, PsycInfo, and Web of Science Core Collection. Six reviewers will independently double-screen articles. Studies will be selected according to the prespecified inclusion and exclusion criteria. Data will be extracted and entered into suitable worksheets. The US-based National Heart, Lung, and Blood Institute's Study Quality Assessment Tool for Observational Studies will be used to assess the quality of all eligible primary studies. The results will be presented in a descriptive and narrative synthesis. If the type and quality of data are suitable, meta-analyses will be conducted. Study reporting will follow the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement.

RESULTS

Data collection started in September 2020, and the literature search was updated in July 2021. Data synthesis is ongoing, and the literature search will be updated in October 2022.

CONCLUSIONS

This review will be valuable to relevant stakeholders, including clinicians and health care professionals, intervention developers, and decision makers in health care. It lays a comprehensive foundation for understanding the determinants of physical activity to inform the design of secondary prevention interventions relevant to the cardiac population.

Polysaccharide-protein complex from coelomic fluid of Dendrobaena veneta earthworm exerts a multi-pathway antiplatelet effect without coagulopathy and cytotoxicity

There is a pressing need to identify novel antiplatelet agents, an alternative to acetylsalicylic acid and thienopyridines, to broaden the prevention of cardiovascular events, the leading cause of global morbidity and mortality. Invertebrate coelomocytes structurally and functionally resemble the thrombocyte-like cells of vertebrates; therefore, the coelomic fluid in which they are suspended may contain agents controlling their clumping abilities. However, whether coelomocytes-free coelomic fluid may also affect human platelet activities was not a subject of any study. This study aimed to screen the in vitro antiplatelet and anticoagulant activities of the polysaccharide-protein complex from Dendrobaena veneta coelomic fluid (25-100 µg/mL) (PPC-DV). All tested fluid concentrations induced significant (42.4-52.5%) inhibition of adenosine-5'-diphosphate (ADP)-induced aggregation of human platelets at a level comparable to that of 140 µmol/L acetylsalicylic acid. Its relevant antiplatelet effect (27.2-45.9%) was also evidenced in the thrombin receptor-activating peptide-6 (TRAP-6) assay. Moreover, 50 and 100 µg/mL of PPC-DV inhibited arachidonic acid-inducible aggregation. No coagulopathic or cytotoxic effects of PPC-DV were observed. The study indicates that PPC-DV, at a concentration of at least 50 µg/mL, exerts a favorable antiplatelet effect by targeting at least three pathways (P2Y₁₂ receptor, cyclooxygenase-1, and protease-activated receptor-1), justifying further experimental and clinical investigations on its use in cardiovascular disease prevention.

The Impact of Frame Running on Quality of Life in Young Athletes With Mobility Limitations

Purpose

The para-athletic sport Frame Running is developed for persons with neurological impairments causing severe limitations of walking ability. Participating in sports can contribute to a better quality of life (QoL). It is unknown if participation in Frame Running contributes to QoL in children with mobility limitations. This study aims to explore the changes in QoL in children and youth who started Frame Running.

Materials and Methods

We conducted a cross-sectional study amongst young Frame Running athletes with mobility limitations due to various underlying causes, aged 6–19 years, who are members of one of the Frame Running groups in the Netherlands. For 62 athletes, parents completed the Psychosocial Impact of Assistive Devices Scale (PIADS) questionnaire (subscales: competence, adaptability, and self-esteem). For six athletes, parents were interviewed to obtain more in-depth insight in the perceived changes in the QoL of their children.

Results

Parents (of 58% boys, mean age 12 years 4 months; SD 3 years 3 months; 52% supported walkers) reported a significant positive change on all three subscales of the PIADS questionnaire since their children started Frame Running. Most change was experienced in the items performance, the ability to participate, happiness and self-confidence. Quotes of the parents who were interviewed elucidated these changes.

Conclusion

Frame Running increased QoL in young athletes with a mobility limitation. Frame Running may therefore be advised for these children and youth to improve QoL.

The UP150: A Multifactorial Environmental Intervention to Promote Employee Physical and Mental Well-Being

Physical activity (PA) is a major health factor and studies suggest workplaces could promote PA by modifying office design, motivational strategies and technology. The present study aims to evaluate the efficiency of UP150, a multifactorial workplace intervention for the improvement and maintenance of the level of physical fitness (PF) and wellbeing. Forty-five employees were randomly divided into the experimental (EG) and control (CG) groups. The PF was assessed pre-post intervention using the cubo fitness test (CFT), the amount of PA was evaluated using the IPAQ questionnaire and accelerometers while the workload was assessed using the NASA-TLX questionnaire and psycho-physical health by using the SF-12 questionnaire. The EG worked in UP150 offices while the CG worked in their usual offices for 8 weeks. The EG and CG came back 4 weeks after the intervention for CFT retention. The EG improved CFT motor efficiency and the amount of moderate PA, while it reduced mental load. The EG retained reached motor efficiency levels 4 weeks after the intervention. No differences were found in IPAQ. The UP150 demonstrated to be a proactive environment and to be efficient in the promotion of PA, improving PF and mental health while decreasing mental load.

Preliminary Efficacy of an Emotion Regulation Intervention on Physical Activity and Depressive and Anxious Symptoms in Individuals in Cardiac Rehabilitation

BACKGROUND

For the 720 000 Americans expected to experience a new acute cardiac event this year, cardiac rehabilitation is an important part of recovery. Symptoms of depression and anxiety undermine recovery efforts, leaving recovering patients at risk for diminished functional capacity and heightened risk of mortality. Poor emotion regulation can worsen symptoms of depression and anxiety and hinder recovery efforts.

OBJECTIVE

The purpose of this randomized controlled trial was to evaluate the early efficacy testing of a theoretically based emotion regulation treatment (Regulating Emotions to Improve Self-management of Nutrition, Exercise, and Stress [RENEwS]) designed to assist survivors of an acute cardiac event in cardiac rehabilitation to optimize recovery.

METHODS

Survivors of an acute cardiac event in cardiac rehabilitation (n = 30, 83% men) were randomized to five 1-hour in-person group sessions of RENEwS or a phone-based attention-control group. Participants completed measures of depression and anxiety symptoms at 3 time points. Moderate to vigorous physical activity (MVPA) was objectively measured for 7 days at each time point using waist-worn actigraphy monitors. Between-group differences were calculated using analysis of variance with Cohen f effect sizes calculated to evaluate initial efficacy.

RESULTS

There was no statistically significant difference in depression, anxiety, or MVPA over time based on group assignment (all P > .05). Compared with attention control participants, in RENEwS participants, preliminary effects showed greater reductions in depression (Cohen f = 0.34) and anxiety (Cohen f = 0.40) symptoms but only modest improvements in MVPA from baseline to 5 months (Cohen f = 0.08).

CONCLUSIONS

Findings show that RENEwS is a promising emotion regulation intervention to enhance cardiac rehabilitation and potentially decrease symptoms of depression and anxiety.

Effectiveness of community-based cardiovascular disease prevention interventions to improve physical activity: A systematic review and meta-regression

Cardiovascular diseases (CVDs) remain a leading cause of morbidity and mortality globally. Despite preventive community-based interventions (CBIs) seem efficacious in reducing CVD risks, a comprehensive up-to-date synthesis on the effectiveness of such interventions in improving physical activity (PA) is lacking. We performed a systematic review and meta-analysis of community-based CVD preventive interventions aimed at improving PA level. MEDLINE, EMBASE, CINAHL, Cochrane register and PSYCINFO databases were searched in October 2019 for studies reported between January 2000 and June 2019. We assessed the methodological quality of included studies using the Cochrane risk of bias tools. We performed a random-effects meta-analysis and meta-regression to pool estimates of various effect measures. Results are reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guideline. Our study protocol was registered in the PROSPERO database (CRD42019119885). A total of 44 randomized and 20 non-randomized controlled studies involving 98,919 participants were included. Meta-analyses found that CBIs improved the odds of attaining the recommended PA level (at least 150 min of moderate and vigorous PA (MVPA)/week) at 12 month (OR: 1.62; 95%CI: 1.25-2.11) and 18 to 24 months of follow-up (OR: 1.46; 95%CI: 1.12-1.91). Furthermore, interventions were effective in improving metabolic equivalents of task at 12 month (standardized mean difference (SMD): 0.28; 95% CI: 0.03-0.53), MVPA time at 12 to 18 months (SMD: 0.34; 95%CI: 0.05-0.64), steps per day (SMD: 0.32; 95%CI: 0.08-0.55), and sitting time (SMD: -0.25; 95%CI: -0.34 to -0.17). Subgroup analyses found that interventions in low- and middle-income countries showed a greater positive effect on attainment of recommended PA level (OR: 1.40; 95%CI: 1.02-1.92) than those in high-income countries (OR: 1.31; 95%CI: 0.96-1.78). Moreover, interventions targeting high-risk groups showed greater effectiveness than those targeting the general population (OR: 1.76; 95%CI: 1.30-2.39 vs. 1.17; 95%CI: 0.89-1.55). In conclusion, community-based CVD preventive interventions have a positive impact on improving the PA level, albeit that relevant studies in lower-middle and low-income countries are limited. With the rising burden of CVDs, rolling out CBIs targeting the general population and high-risk groups are needed to control the growing CVD-burden.

Lifestyle management to prevent atherosclerotic cardiovascular disease: evidence and challenges

Lifestyle management is the cornerstone of both primary and secondary prevention of atherosclerotic cardiovascular disease (ASCVD) and the importance of lifestyle management is emphasised by all major guidelines. Despite this, actual implementation of lifestyle management is poor. Lifestyle modification includes smoking cessation, weight loss, dietary change, increasing physical inactivity, and stress management. This review summarises evidence-based opportunities and challenges for healthcare professionals to promote healthy lifestyles at an individual level for the prevention of ASCVD.

Community-Dwelling Older Adults and Physical Activity Recommendations: Patterns of Aerobic, Strengthening, and Balance Activities

Though it is known that most older adults do not meet the recommended physical activity (PA) guidelines, little is known regarding their participation in balance activities or the full guidelines. Therefore, we sought to describe PA patterns among 1,352 community-dwelling older adult participants of the Adult Changes in Thought study, a longitudinal cohort study exploring dementia-related risk factors. We used a modified version of the Community Healthy Activities Model Program for Seniors questionnaire to explore PA performed and classify participants as meeting or not meeting the full guidelines or any component of the guidelines. Logistic regression was used to identify factors associated with meeting PA guidelines. Despite performing 10 hr of weekly PA, only 11% of participants met the full guidelines. Older age, greater body mass index, needing assistance with instrumental daily activities, and heart disease were associated with decreased odds of meeting PA guidelines. These results can guide interventions that address PA among older adults.
