#Living Longer, Sicker Lives? Make Lifestyle Changes To Remain Healthier In Old age Life expectancy across the world is growing, but the number of those extra years in which wee healthy is not rising at the same rate. This adds to the demographic time-bomb of a greater number of older people suffering from ill-health. Yet, according to the Global Burden of Disease study published in the Lancet, of the top ten health risks most are related lifestyle and within our power to change. Between 1990 and 2013, life expectancy in the UK increased by 6. 2 years for men to 79.1 years and by 4. 4 years for women to 82.8 years. However, the amount of this gain expected to be lived in good health increased by only 4. 7 years for men and 3. 3 years for women. While a similar improving trend was observed in most countries across the globe, in dozens of countries including Belarus, Belize, Gabon, Guyana, Paraguay, Syria and all of southern Sub-saharan africa, healthy life expectancy was lower in 2013 than in 1990. Interestingly, this is also the first time that improvements to healthy life expectancy in the developing world (5. 4 years for men and 6. 4 years for women) are greater than those in the developed world (3. 9 years for men and 2. 8 years for women). ) Chronic Disease And Disability A surprising fact is that, nowadays, fewer than 4%of people are completely free of any health problem, with more people living with chronic and under-reported illnesses. The number of years lived with disability have increased in almost every country, attributable to the growth of chronic diseases such as cardiovascular and respiratory diseases, cancer, back pain, mental health disorders, dementia, road injuries, HIV /AIDS and malaria. This has increased also the demand for care. A comparison of years of life lost between regions of the UK, the EU15 group of countries plus Australia, Canada, Norway and the US, shows that England worst affected region the northwest (with northeast England close behind) is similar to Scotland, Northern ireland and the US. The East midlands is the UK average, equivalent to France, Canada and Germany, while better off regions such as the southwest, southeast and London are closer to Spain, Australia and Norway. Factors Within Our Control We could live longer and healthier if we tackled the main health risks that affect us. Globally, the leading ten risks are smoking, obesity, high blood pressure, diabetes alcohol use, high cholesterol, kidney disease, low physical activity, diets low in fruits and vegetables and drug use. These are drawn from 79 biological, behavioural, environmental and occupational factors. The list is similar in the UK, with smoking, high blood pressure, obesity at the top and low physical activity also ranking highly, comparable to Australasia, Ireland and the US. Among developed countries there is some variation: alcohol use is a bigger problem in Belgium, Denmark, Finland and South korea, while smoking is less of a problem in Finland, Israel and Singapore, for example. The same is true within the UK, where Wales scored worse in physical activity but better in blood pressure, or where drug use was a greater problem in the southwest, southeast and the east of England than elsewhere. Of metabolic (biological), environmental, or behavioural (lifestyle) factors affecting health, it is lifestyle factors that carry the most weight. The Future We are now entering an era when fighting for funding to tackle a single disease in isolation is no longer effective. Health problems tend to cluster from childhood to adulthood and then around the end of life They also share both biological and environmental risks. The main risk factors leading to chronic diseases such as high blood pressure, obesity, smoking and heavy alcohol consumption might result from family problems, social inequality or poverty, beliefs or customs of particular subcultures , selfish business models, bullying or violence, poor education (awareness), depressive mood and even the changeable weather. Current prevention and interventions programmes and social and health policies aimed at reducing the leading risks might have limited effects. Instead, we should focus on the context and mechanism of actions of these risks. We, therefore, need to restructure human society in each country with systematic examination and improvements in every aspect of human life including politics, the occupational (for example, more healthcare and less business; shorter working hours with lower unemployment rates), the built environment (including housing and neighbourhoods renewal, the transport system, etc), consistent culture, education and parenting, hobbies and so on. This is the grand challenge that faces us in the next decade
