To prevent one breast cancer over 5 years, 2451 women need to have mammogramsB. GPs need to advise 102 people about physical activity for one person to achieve an increase in physical activity with a 20–30% risk reduction in all cause mortalityC. GPs need to treat 67 people with hyperlipidaemia who have 1% risk of coronary heart disease with a lipid lowering agent for 5 years to prevent one cardiovascular disease eventD. To identify one colorectal cancer, 1374 people need to have bowel cancer screening.

  27. SLIDE PRESENTATION The impact of physical activity on health

  28. There are many health benefits of physical activity These include: • all cause mortality risk reduced by 50%• cardiovascular disease risk reduced by up to 50%• hypertension prevention and management• stroke risk reduced by up to 30%• type 2 diabetes prevention (risk reduced by 30–50%) and management.

  29. There are many health benefits of physical activity These include: •cancer risk (colon, breast) reduced•osteoarthritis management (pain control, maintenance of muscle strength, joint structure and function)•osteoporosis risk reduction•falls risk in the elderly reduced by resistance exercises•weight management and reduction (when combined with dietary changes)•mental illness (anxiety, depression and subjective feelings of stress) prevention and management.

  30. Health impact – overall mortality Low levels of physical activity are associated with marked increases in all cause mortality rates. In 2003:•there were 13 491 deaths in Australia attributable to physical inactivity •physical inactivity was responsible for 6.6% of the total burden of disease and injury in Australia.Energy expenditure is positively associated with longevity.

  31. Health impact – risk of cardiovascular disease The risk of fatal and nonfatal cardiovascular events is 1.5–2 times higher for physically inactive people than for moderately active people.•Regular physical activity throughout life reduces the incidence and fatality rate of cardiovascular disease by up to 50%•For sedentary patients it may never be too late to become physically active.

  32. The greatest health benefit of physical activity is seen in people who change their physical activity status from sedentary to moderately active.

  33. Health impact – existing cardiovascular disease Having cardiovascular disease (CVD) does not prevent physical activity – it makes it more important.•By being regularly active, people with CVD can decrease their chance of dying from another heart attack by 25% •Exercising by walking three times per week, to the level that causes pain, relieves intermittent claudication for many people.

  34. Health impact – hypertension prevention and management, stroke risk reduced by up to 30% Regular physical activity can reduce: •blood pressure by an average of 4 mmHg (SBP) and 2.5 mmHg (DBP)•decrease the risk of ischaemic stroke in older adults•favourably influence lipid profiles.

  35. Health impact – type 2 diabetes prevention and management Regular physical activity can:•improve insulin sensitivity and reduce the risk of type 2 diabetes by 30–50%•delay or prevent progression to diabetes for people with prediabetes (impaired fasting glucose and/or impaired glucose tolerance)•reduce the risk of type 2 diabetes equally in older and younger age groups•be particularly effective in preventing type 2 diabetes in obese people•reduce the risk of diabetes related death.

  36. Health impact – cancer risk (colon, breast) reduced In primary prevention, routine physical activity is associated with a:• 30–40 % relative risk reduction in the incidence of colon cancer compared to inactive people•20–30 % relative risk reduction in the incidence of breast cancer compared to inactive women.

  37. Health impact – cancer risk (colon, breast) reduced In secondary prevention, physical exercise:•improves the prognosis in people receiving treatment for breast and colon cancer•is associated with reduced cancer related death and reduced recurrences•is associated with an improvement in overall quality of life and health status.

  38. Health impact – osteoarthritisWhat is the relationship between exercise and osteoarthritis (OA)? • Recreational sport probably does not cause OA• Excessive activity (high impact and torsional loading) with an abnormally aligned joint may lead to joint degeneration and OA.Overall, benefits of physical activity outweigh the risks in the role in:• pain control of osteoarthritis• maintaining muscle strength and joint structure and function.

  39. Health impact – osteoporosis Routine physical activity is important in:•preventing loss of bone mineral density and osteoporosis, particularly in postmenopausal women•secondary preventive action to fight against osteoporosis•reducing the risk of fractures among active people.

  40. Health impact – the risks of falls in the elderly reduced by resistance exercises •Falls in the elderly are a major cause of morbidity and mortality •Musculoskeletal fitness is important for elderly people and can help maintain functional independence•Regular physical activity can prevent frail elderly people losing their remaining musculoskeletal reserve and entering a cycle of inactivity and further dependence.

  41. Health impact – weight management and reduction (when combined with dietary changes) •Exercise has a positive effect on body weight (and CVD risk factors) in people who are overweight or obese. This is particularly so if combined with a healthy eating plan.

  42. Health impact – mental illness prevention and management •Aerobic exercise training has antidepressant and anxiolytic effects and protects against harmful consequences of stress in adults•Activity in the elderly can lower depression scores•Exercise has positive short term effects on self esteem in children and young people.

  43. Health impact – other benefits Other benefits of physical exercise:• improved cognitive function and dementia prevention•improved asthma control and exercise tolerance in chronic obstructive pulmonary disease and cystic fibrosis•increased muscle strength in patients with peripheral neuropathy•decreased symptoms of fibromyalgia (aerobic exercise)•some patients with chronic fatigue syndrome benefit from exercise•may have a role in the treatment of sleep problems in older people.

  44. Does physical activity have any risks? Physical activity is a ‘wonder drug’, but does have some risks. The following conditions need clinical assessment before exercise: • unstable angina• uncontrolled hypertension• severe aortic stenosis• uncontrolled diabetes• complicated myocardial infarction (within 3 months)• untreated heart failure or cardiomyopathy• symptoms such as chest discomfort or shortness of breath on low exertion• resting heart rate >100 bpm.

  45. How much exercise is enough? A. 1 hour of any activity that raises heart rate to 120% of resting rate, three times per weekB. At least 40 minutes vigorous activity, at least 3 days per weekC. Moderate intensity physical activity for at least 30 minutes on most or preferably all days of the week.

  46. Promoting physical activity

  47. Reflection on current practice 1. What is your current role in promoting physical activity?2. What strategies do you use to promote physical activity?3. What percentage of your patients do you talk to about physical activity?4. What percentage of your patients with conditions would benefit from physical activity?5. What are the most common conditions or attributes patients present with that would benefit from physical activity?

  48. There is evidence that GP intervention promotes physical activity •Professional guidance, self direction plus ongoing professional support can lead to a consistent increase in physical activity over a year•Home based activity was more effective than activity at a special facility (eg. gym)•Interventions should be targeted toward particular groups and tailored to the individual.
