A study finds that about half of South Korean men aged above 30 are overweight and legs of South Korean women steadily grew longer over the past decade. 

The Korean Agency for Technology and Standards under the Ministry of Trade, Industry and Energy announced the results of its seventh study on South Koreans’ body sizes.

According to the study results, about 50 percent of South Korean men over the age of 30 are overweight with a body mass index(BMI) surpassing 25.

The length of women’s legs increased in all age groups of women older than 20 since 2004.

The leg length-to-height ratio of women aged between 20 and 24 increased from zero-point-452 in 2004 to zero-point-460 in 2015. There was no significant change in the length of South Korean men.

The average height of South Korean men increased five to seven-point-six centimeters since 1979, while that of women increased three-point-seven to six-and-a-half centimeters. The average height of a South Korean man aged between 30 to 34 years stood at 173-point-seven centimeters. Women in the same age bracket was as tall as 160-point-two centimeters on average. 

Dong Seoul University conducted the study on about 64-hundred South Koreans aged between 16 and 69 in five regions nationwide for five months from June last year.
