Rationale: Body composition is clinically significant as an overall reference value of an individual’s health as well as a diagnostic or prognostic indicator for various chronic and age-related illnesses, such as obesity and sarcopenia. This large-scale study aims to present descriptive statistics on body composition data of 217,950 Korean adults (male 82,901, female 135,049) from 2014 to 2020 using bioelectrical impedance analysis (InBody770).
Methods: All the data measured with equipment of InBody Co., Ltd. is saved in the server of the company and can be extracted by need. This study was conducted after the approval of Korea University Anam Hospital Institutional Review Board (IRB - 2021AN0086), using only body composition data excluding personal identification data. InBody770 is usually located in health examination centers, public health centers, general hospitals, hotels, and large fitness centers nationwide. Location information of individual data was unavailable. Body composition data of 217,950 Korean adults (82,901 men and 135,049 women, mean age 40.6 years, range of age 20-90 years) measured with Direct Segmental Multi-Frequency Bioelectrical Impedance Analyzer (InBody770; InBody, Seoul, Korea) between January 16th, 2014, and March 6th, 2020 were used.
Results: Results showed males in their 20s to early 30s undergo an increase in PBF, followed by a decrease in SMM after hitting a peak at age 37. Females showed a different pattern, with PBF increase and SMM decrease occurring simultaneously from the age of 41. This pattern can be explained by change in hormonal status and resting metabolic rate during aging, and non-biological factors such as decreasing physical activity with age and nutritional changes.
Conclusion: Lifestyle modification with aerobic exercise and diet control is recommended for men in their 20s and early 30s to prevent fat increase. Men after late 30s and women after early 40s should work on weight training to prevent muscle loss.
