International healthcare patients who do not smoke may be more likely to suffer from obesity, new research has indicated.
The study, led by Dr Laurence Gruer of NHS Health Scotland, found that those who do not use cigarettes are not only more prone to weight problems, but also diabetes, heart attacks and strokes as a result.
It is the result of some 28 years of research, with more than 3,600 women in Scotland chosen to be part of the study as early as 1972.
Participants who smoke had a 40 per cent chance of being obese, while that figure rose to 80 per cent in ladies who never light up.
Dr Gruer told people who do not smoke and maintain a healthy weight that "even if you earn below average income and live in a more disadvantaged area, you can still expect to live a long and healthy life".
The Office for National Statistics recently found that 48 per cent of smokers are keen to give up the habit.
