Scotland's biggest city was the unhealthiest place in the UK last year, according to a study.

Almost four in 10 Glaswegians were classified as either being obese or morbidly obese, the Nuffield Health charity found.

The city also had the biggest proportion of smokers (29%) and came fifth in a list of UK locations where people get the least sleep.

The study collected data from around 40,000 people keen on improving their fitness.

It found that 36% of men and 31% of women in Glasgow were obese, having a body mass index (BMI) of over 30, and 5.1% were morbidly obese, with a BMI of over 40.

East Kilbride was the fifth-placed obesity hotspot in the UK, with around a quarter classified as obese.

In Aberdeen 15% of people were obese or morbidly obese, while 19% of them smoked.

Dr Sarah Dauncey, the medical director of Nuffield Health, said: "Obesity is a serious problem in Glasgow, which must be tackled to ensure people live healthier and longer lives.

"Evaluating your health is important and the first step is to take control of your health and wellbeing."

The data was collected in 2010.
