Objective To analyze the characteristics and development trend of body composition and fat distribution of urban residents in urban areas of Lanzhou City, Gansu Province with age and provide a theoretical basis for improving the physical condition of residents. Methods Bioelectrical impedance method (Japan MC-180 type human body composition analyzer) was used to test 1357 male and female residents, and the results were statistically analyzed. Results The body fat percentage and waist-hip ratio (WHR) of male and female residents aged 20-79 increased with age. The total amount of protein, total muscle mass, putative bone mass, body water and body mass index (BMI) increased at first and then decreased with the increase of age.
