Early studies have shown that, during the adult aging process, body fat distribution will gradually shift from limbs to trunk. Truncal fat, especially increased visceral fat is associated with metabolic disorders. Objective: To build the best curve model between BMI and waist-hip-fat ratio (WHFR) among Tianjin males aged 20-69 years old; Explore the obesity sensitive periods of BMI and WHFR among subjects. Methods: The subjects were 8 036 males aged 20 to 69 years who were test by Tianjin Municipality Physical Fitness Surveillance Center from January, 2011 to December, 2013. The test indexes included body fat mass, muscle mass, skeletal muscle mass, WHFR, fat-free mass, height and body weight. Curve fitting was applied to the relationship between BMI and WHFR, and the optimal model between BMI and WHFR was established according to the values of A1C and R. The obesity sensitive periods were anglicized according to the annual incremental values. Results: (1) First to sixth order polynomials were valid in all ages, and AIC and R were-24 001.93, 0.849;-24 265.13, 0.854;-24 263.17, 0.860;-24 289.44, 0.866;-24 299.97, 0.866; and-24 298.51, 0.860, respectively. (2)Annual incremental peaks of BMI among males were in 20~24 years ~ 25~29 years, 35~39 years ~ 40~44 years, 50~54 years - 55-59 years, 60-64 years - 65~69 years, while valley values appeared in 30-34 years ~ 35~39 years, 45~49 years - 50~54 years. Annual incremental peaks of WHFR were in 20-24 years - 25~29 years, 35-39 years- 40~44 years, 60~64 years ~ 65~69 years, respectively, while valley values appeared in 30~34 years-35-39 years, 45-49 years ~ 50- 54years, respectively. Conclusions: (1) The fifth order curve fitting for males was confirmed as the best curve model between BMI and WHFR during 20~69 years old. (2) Incremental changes with age of BMI and WHFR among males suggested there were sensitive periods for obesity, which were crucial periods for physical activity and clinical intervention.
