Korean men are getting fatter and women’s legs are getting longer, according to a survey on Korean body size and obesity released Monday.

The poll of 6,413 people, which was conducted by the Korean Agency for Technology and Standards under the Industry Ministry, showed that nearly half of Korean men in their 30s are obese.

It said some 52 percent of those aged between 35 and 39 had a body mass index of 25, a measure of body fat based on height and weight. A BMI of 25 or over is regarded as obese in Korea.

The study also showed that the ratio of leg length to height rose to 0.460 in 2015 from 0.452 in 2004 in females aged between 20 and 24. For men, however, the ratio showed no significant change.
