Overview
Physical activity, described in its broadest sense (including walking or cycling for transport, gardening and housework as well as sport or deliberate ‘exercise’) is a critical public health issue. This is not only because lack of physical activity is associated with significant risks to many aspects of health, but also because there is a high prevalence of physical inactivity: around two-thirds of adults fail to achieve recommended physical activity levels. There is no significant difference between physical activity levels for adults in the South East compared to England, with 37% of men and 24% of women classed as active.
Aspects of health and illness that can be improved by increasing physical activity include coronary heart disease, diabetes, cancer, positive mental health, weight management and musculoskeletal conditions such as osteoporosis. Inactive and unfit people have almost double the risk of dying from coronary heart disease; and cardiovascular disease, including heart disease and stroke, and cancer are the major causes of death in England, together accounting for almost 60% of premature deaths. Physical inactivity, along with unhealthy diets, has contributed to the rapid increases in obesity in both adults and children.
Besides the human costs of inactivity in terms of mortality, morbidity and quality of life, an es timate for the cost of inactivity in England is £8.2 billion annually (Game Plan, Strategy Unit, 2002).
Recommended levels of physical activity for children and young people are at least 60 minutes of at least moderate intensity physical activity every day, and for adults including older adults at least 30 minutes a day of at least moderate intensity physical activity on 5 or more days of the week, where ‘moderate intensity’ is equivalent to a brisk walk.
Much of the decline in overall physical activity is due to trends in our society that reduce opportunities for activity, such as increased car travel and car ownership, a decline in walking and cycling, fewer manual jobs, more labour-saving devices, and a rise in sedentary leisure activities such as watching TV and videos. Also lack of time is a very common barrier to physical activity.
There is evidence that public health action on a number of levels is helpful in increasing levels of physical activity. These include advocacy for policy and environmental changes; developing strategies such as local transport plans; involving primary care; running community programmes; targeting adults over 50; targeting young people via a whole school approach and ensuring proper monitoring, evaluation and data collection.
The South East region is well advanced in developing policy and action on physical activity.
