Environments in the UK have been designed to make our lives physically easier: cars, trains, lifts, washing machines -even the humble remote control. It's no surprise then that around 4 out of 10 of us are inactive. 1 While many people may know that physical activity is good for them, they struggle to do any. And, while the phrase '5-a-day' for the consumption of fruit and veg is well known, there's no equivalent for physical activity. Perhaps that's why only between 8% and 18% of people in the UK were able to recall that the Chief Medical Officers' guidance is at least 150 minutes of moderate exercise per week. [2][3][4] GPs faired marginally better: just 20% could recall the guidance. 5 The consequences of inactivity in our population are well known: high levels of cardiovascular disease, diabetes, cancer, and poor mental health. These are self-evident from Fingertips, the public health statistics gateway for general practices in England. Consider, for instance, the under 75 mortality rate from preventable cardiovascular diseases. According to Fingertips, if we look at towns across the country, the mortality rate correlates linearly with inactivity with a correlation coefficient of r = 0.67 (moderately strong). 6 If inactivity increases in a town, so do preventable deaths. Given all the other determinants of health -alcohol, diet, drugs, access to health care, education, employment, environment, and poverty (and so on) -this is quite remarkable.As you might expect from this, healthy life expectancy (HLE) also correlates with levels of inactivity. Figures from the Office for National Statistics show that HLE for males in the UK is just 62.8 years 7 -less time than the Queen has been on the throne. Shockingly, only four towns have a HLE at birth for males of ≥70 years: Richmond upon Thames, Rutland, Wokingham, and, of course, Windsor. Notably, they all have activity levels of at least 68% and inactivity levels <21%.
