Exercise as it relates to Disease/Physical activity to reduce the risk of cardiovascular disease
This Wikibooks page is a critique of "Effectiveness of a physical activity program on cardiovascular disease risk in adult primary health-care users: the “Pas-a-Pas” community intervention trial" by Arija et al. published in BioMed Central Public Health in 2017.
What is the background to this research?Edit
Cardiovascular disease is any disease that affects the heart or blood vessels. This includes coronary heart disease, cardiomyopathy and stroke . Exercise is critical to the prevention and treatment of cardiovascular disease.
Cardiovascular disease has been the leading cause of deaths in Australia for many years with 43,963 deaths in 2016 . In Spain where the intervention was conducted there is also a high prevalence of cardiovascular disease with 53,101 deaths, or 16.92% of all deaths in 2017. On a worldwide scale 17.5 million people or 31% of all mortality died from cardiovascular disease in 2012. The World Health Organization estimated that 23.6 million people will be dying each year from cardiovascular disease by 2030.
Risk factors increasing the risk of cardiovascular disease include:
Where is the research from?Edit
Location of the StudyEdit
The study was conducted at 4 primary care centres in Reus, Catalonia, Spain.
Location of the AuthorEdit
Victoria Arija is affiliated with Rovira i Virgili University in Tarragona, Spain. Victoria researches chronic diseases with association to 123 publications on ResearchGate and has been published 7 times in BMC Public Health .
BMC Public Health is the largest open access, peer-reviewed journal with a focus on public health. BMC Public Health addresses the social, behavioural and environmental effects on health and disease, investigating how different interventions make for a healthier community.
What kind of research was this?Edit
Arjia V et al. conducted a randomised controlled community intervention . Randomised controlled interventions are thought to be the gold standard, reduce bias and be a thorough method of evaluating whether a cause-effect relationship exists between the intervention and the outcome.
What did the research involve?Edit
This research intervention involved collecting clinical history, baseline dietary intake and physical activity levels. The participant's cardiovascular risk factor was also measured using the Registre Gironí del Cor scale. This scale assessed blood pressure, smoking status, waist circumference, weight, BMI and cholesterol.
The intervention consisted of a control group of 104 people and intervention group of 260 people. The participants completed 120min/week walking (396METs/min/week) and a social gathering once a month.
This article did not address the risk of human error in initial measurements. Blood pressure was measured with a manual sphygmomanometer 3 times and an average recorded. There is the possibility the clinician could mishear the blood pressure reading or left inadequate time between the tests which would elevate the participant's blood pressure . The cardiovascular risk factor scale Registre Gironí del Cor asks whether a participant smokes with simply yes or no. This does not take into account the quantity of cigarettes the participant smokes per day. This would have a major effect on the narrowing of arteries and their lung function therefore affecting their cardiovascular disease risk and ability to participate in walking interventions . Studies that have found the Registre Gironí del Cor risk factor scale to underestimate the risk of cardiovascular disease.
What were the basic results?Edit
|Key Factor||Result of Intervention||P-Value|
|Physical Activity||+774.81 METs/min/week ||0.026 |
|Systolic Blood Pressure||-6.63mmHg ||0.029 |
|Total Cholesterol||-10.12mg/dL ||0.006 |
|LDL-Cholesterol||-9.05mg/dL ||0.009 |
A p-value <0.05 was considered to be of statistical significance .
- Two years after intervention, the incidence of adverse cardiovascular events remained 8% lower in the intervention group participants and their maintenance of regular physical exercise was 45.6% higher than the control group participants.
What conclusions can we take from this research?Edit
Results show that walking over extended periods of time reduces cardiovascular disease prevalence. This is through decreased systolic blood pressure, LDL-cholesterol and total cholesterol. These results aligns with current research findings .
The method could be adapted to reduce the risk for error. There should be more research in this area and awareness raised that cardiovascular disease is the biggest killer of Australians and that exercise can reduce the risk and severity of the disease.
If you consider that you or a family member may have cardiovascular disease book an appointment with your local general practitioner. They will access your medical history and order testing if necessary .
To get an individualised exercise plan you should contact an Exercise Physiologist. They have the anatomical knowledge to write an exercise plan for cardiovascular disease.
