| Objective To explore the differences in body composition detection indicators of adults of different genders and ages in Anhui province, providing data reference for health guidance and chronic disease prevention in the adult population of Anhui province. Methods A retrospective analysis was performed on 4 944 health checkups from January to December 2018 at the Health Management Medical Center of the First Affiliated Hospital of Anhui Medical University.The research objects were divided into male group (2 556) and female group (2 388) by gender; then the male and female groups weredivided into 5 groups according to their age (18 ≤ y<30 years old; 30 ≤ y<40 years old; 40 ≤ y<50 years old; 50 ≤ y<60 years old;y ≥ 60 years old).The differences in body composition measurement indicators(body mass index (BMI), body fat mass, body fat percentage, waist-hip ratio,visceral fat area, fat-free body mass, skeletal muscle mass, bone mineral content,protein content and edema index)were compared between male and female groups. At the same time, the changes of the above-mentioned body composition measurement indicators in different age groups were analyzed.Results ① According to the results of gender grouping, the body fat mass, body fat percentage and edema index of the female group were higher than those of the male group, and the other indicators were higher in the male group than in the female group (P<0.05).② Male BMI, body fat mass and waist-hip ratio were higher than 18 ≤ y<30 years old in all age groups of 30 ≤ y<60 years(P<0.05);body fat percentage visceral fat area and edema index were higher than 18 ≤ y<30 years old in all age groups of y ≥ 30 yearsold (P<0.05);fat-free body mass, skeletal muscle mass, bone mineral content and protein contentin y ≥ 50 years group were lower than in 18 ≤ y<30 years old group(P<0.05).Female constitutional index,waist-hip ratio and visceral fat area were higher than 18 ≤ y<30 years old in all age groups of y ≥ 30 years old (P<0.05); the body fat mass;body fat percentage and edema index were higher than 18 ≤ y<30 years old in all age groups of y ≥ 40 years old(P<0.05);fat-free body mass, skeletal muscle mass, bone mineral content and protein content in y ≥ 60 years group were lower than 18 ≤ y<30 years old (P<0.05). Conclusion There are gender differences in body composition of adults in Anhui province,the body fat mass of women is higher than that of men, while the male visceral fat area and skeletal muscle mass are higher than those of females. In addition, the body composition also differed among different ages, which is characterized by an increase in the fat mass and edema index at high ages, and a decrease in other fat-freemass. |
