Healthy lifestyles reduce mortality
‘Modest, but sustained, improvements to diet and lifestyle could have significant public health benefits’, finds a study of 4,886 UK adults. Adults randomly selected in 1984–85 were assigned a score according to four unhealthy behaviours at baseline – one point each for: smoking; eating fruit/vegetables fewer than three times a day; less than two hours’ physical activity per week; and weekly alcohol consumption above recommended limits. A total of 1,080 participants died within the follow-up period (mean 20 years) – 431 from cardiovascular diseases, 318 from cancer and 331 from other causes. Adjusted hazard ratios were significantly raised for scores of one, two, three or four points – a score of four was equivalent to being 12 years older in health terms.
