Health of Scotland's population - Obesity


Obesity can reduce people's overall quality of life. It creates a strain on health services and leads to premature death due to its association with serious chronic conditions such as type 2 diabetes, hypertension, and hyperlipidaemia, which are all major risk factors for cardiovascular disease. The two major lifestyle factors associated with the growth of obesity are physical inactivity and poor diet.

Body Mass Index (BMI) is the most commonly accepted measure of general obesity. BMI is calculated by dividing weight (measured in kilograms) by height squared (measured in metres). Adults are classed as overweight if their BMI is 25 to less than 30, obese if their BMI is 30 to less than 40 and morbidly obese if their BMI is 40 or more.

In 2017, 65% of adults aged 16 and over were overweight, including 29% who were obese.  There was a significant increase between 2003 and 2008, when prevalence increased from 62% to 65%. Since 2008, prevalence has stabilised, fluctuating between 64% and 65%.
