Correlation between body mass index and physical qualities and functions in 2 056 adults from Guangzhou / 中国组织工程研究

ABSTRACT

AIM: The auxology-related indexes are important for tissue construction. In this article, we investigated the incidence of overweight and obesity and their effects on physical functions and qualities of Guangzhou adults in 2005. METHODS: 2 056 adults including 1 027 males and 1 029 females were randomly selected from Guangzhou in 2005 for physical examination. The anthropometric data such as body mass and height were collected to calculate body mass index (BMI). The subjects were divided according to the BMI criteria recommend by Group of China Obesity Task Force, and their physical functions and qualities were analyzed. RESULTS: In 2005, the detection rate of overweight and obesity in adult males were 28.7% and 5.2%, and in females were 18.6% and 5.3%. The values of diastole pressure and systolic pressure were increased with BMI, but the change tendency of step index and vital capacity/body mass was decreased with BMI. The rate of hypertension was increased with BMI, and male subjects had higher rate of hypertension than that of female subjects in all groups. Obese adult had the poorest values in vertical jump and sit-and-reach test. Those people with normal BMI had better balance ability than that of overweight and obese people. CONCLUSION: The rates of overweight and obesity in Guangzhou adult show a high level. The physical functions and qualities may be improved when the body mass increases or decreases in a certain range, but obesity has impact to those values.
