Body fat parameters of adult population in Guangxi with the change trend of age / 解剖学报

ABSTRACT

Objective To measure the body fat parameters of adult population in Guangxi, and to explore the characteristics of distribution of fat content with age and gender. Methods A total of 1558 male residents and 2132 female residents were selected by random sampling method . The subjects were divided into 8 groups every 10 years, and the fat parameters were measured and recorded by body composition analyzer. The statistical software SPSS 22. 0 analysed data. Results The total of fat mass and fat content of all parts as well as the subcutaneous and limb fat content of all age groups in Guangxi females were higher than that of the male. The fat content of each part of the male increased first and then decreased with age. It was at the age of 30 that the fat parameters of the male peaked with the highest rates of overweight and obesity. Males had more visceral fat and trunk fat than women at 30-40 years old, and showed predominantly centripetal obesity.Total fat content and fat content of all age groups of female showed a rapid rise at the age of 20-50, and reached a peak at 40 years old. After 50 years old, they slowly decreased and gradually stabilized. The main manifestations of young women were subcutaneous and limb fat increase, which was mainly characterized by centripetal obesity after 40-50 years old, when the rates of overweight and obesity were the highest. Conclusion The body fat content of male and female people in Guangxi increases first and then decreases with age. Twenty-thirty years old of Males and 20-50 years old of female are the key time points for the change of body fat content. In addition of the visceral and trunk fat content, the fat content of different age groups and different parts of female is higher in Guangxi than that of males. The visceral and trunk fat content of Guangxi young adults male is higher than that of females.
