Abstract:
OBJECTIVETo examine the effect of body fat mass and fat distribution on pulmonary ventilatory function among the adult females.
METHODSBased on the multistage cluster sampling principal, we selected 935 healthy adult females with ages of 19-81 years old in Heilongjiang province to conduct the study. Every 10-years old as a age group. Firstly obtain the basic situation through the questionnaire survey, and then measure the height, body weight, waistline, hip circumference, body composition and lung function. FVC, FEV1, PEF, FEF25%, FEF 50%, FEF 75% and MMEF were determined. This study also examined the relationships between percentage body fat (PBF), waist-hip ratio (WHR) and FVC, FEV1, PEF, FEF25%, FEF 50%, FEF 75%, MMEF.
RESULTSPBF of subjects with ages of 19 - 29 years old and over 60 years old were (16.89 ± 5.34)% and (24.39 ± 6.83)%, WHR were 0.77 ± 0.05 and 0.88 ± 0.06, respectively. PBF and WHR tended to increase with age (F = 50.11, P value < 0.01). PBF obesity rates of subjects with ages of 19 - 29 years old and over 60 years old were 3.23% (7/217) and 43.75% (28/64), WHR obesity rates were 19.35% (42/217) and 85.94% (55/64) respectively. PBF obesity rate and WHR obesity rate tended to increase with age (χ(2) = 161.66, P value < 0.01; χ(2) = 159.61, P value < 0.01). PBF obesity groups compared with the normal groups, the former pulmonary ventilation function reduced significantly, of which FEF 50%, FEF 75% and MMEF decreased 2.61%, 19.44%, 10.28%, respectively. WHR obesity groups compared with the normal groups, the former pulmonary ventilation function reduced significantly, of which FEF 50%, FEF 75% and MMEF decreased 7.61%, 23.15%, 12.04%. After adjustment of age, height and body mass index (BMI), PBF was negatively correlated with FVC, FEV1, PEF and FEF25% (r values were -0.14, -0.14, -0.07, -0.07, respectively, all P value s < 0.05); WHR was negatively correlated with FEV1 (r value was -0.07, P value < 0.05) after adjustment of age, height and BMI.
CONCLUSIONPBF augmentation and abdominal obesity among adult females may be the risk factors of pulmonary function impairment.
