Men are more likely to give up smoking than women, while older smokers are also more likely to kick the habit, according to a new report.
The study, commissioned by NICE and undertaken by the UK Centre for Tobacco Control Studies, examined the success rate of different groups of people who accessed NHS smoking cessation services.
It revealed that the services have succeeded in reducing inequalities in smoking prevalence among specific groups, but differences still exist, as do cessation success rates.
The researchers reviewed published studies from between 1990 and 2007 to establish how well NHS smoking cessation services have performed.
The study showed that older smokers are more likely than young smokers to successfully quit, some men appear to be more successful at quitting than women despite the fact that more women attend the smoking cessation services, and more disadvantaged groups face greater challenges when giving up smoking.
The findings support other international research that also suggests while women are highly motivated to quit smoking, men may be more likely to succeed when they access services to help them stop.
The UK remains the only country in the world to have a comprehensive, free-at-the-point-of-use cessation services and the study suggests that these services do provide effective support for smokers who want to quit.
