A study by the University of Liverpool has found that a decrease in smoking rapidly reduces mortality rates in individuals and entire populations within six months.
Researchers found that a reduction in smoking has a positive impact on mortality rates in both individuals and populations within six months. Likewise, dietary improvements get very positive results within one to three years.
Professor Simon Capewell said: “Our research found that smoking bans and diet improvements powerfully and rapidly reduce chronic disease in both individuals and in the wider population. This actually happens quickly, within a far shorter timescale than had previously been assumed; within months and years rather than decades. This discovery means that policies such as smoking bans or reducing saturated fats are effective at improving health and would save the NHS millions very rapidly.”
The study found that policies that reduce smoking consistently have a rapidly positive effect on mortality rates and hospital admissions in countries and communities around the world. After smoke-free legislation was introduced in Scotland in 2006, hospital admissions for acute coronary syndrome decreased by 17% with a 6% decrease in out-of-hospital cardiac deaths.
