Share of obese persons has increased among persons aged 20 to 64

The percentage of those with a body mass index of 30 kg/m² or more, calculated on the basis of self-reported weight and height, has increased continuously since the late 1980s. At the beginning of the 2010s, the share of obese people was over double that at the beginning of the 1980s. Over the 2010s, the share of obese people has still grown a little.

The percentage of obese women was slightly lower than that of men, on average, in the 1990s and early 2000s, but from 2004, differences between the genders have been minor in this regard. In 2015, the share of obese persons among those aged 20 to 64 was 19 per cent for both men and women.

Description of indicator

The question on height was: ’What is your height?’ The question on weight was: ‘What is your weight, measured when wearing light clothing?’ The actual calculation of BMI is weight divided by height squared. Body mass index is the most commonly used method of determining the degree of obesity. Body mass index = 30 kg/m² is the internationally approved limit for obesity.
