身體質量指數與代謝症候群指標關係之性別差異研究

Background: The World Health Organization (WHO) suggested that the Body Mass Index (BMI) or hip waist ratio can be used to determine obesity in metabolic syndromes. However, the Department of Health of Taiwanese government uses only waist circumference rather than BMI. But the prevalence of using BMI as an indicator of obesity among people in Taiwan, and the relationship between BMI and metabolic syndromes was still controversial on gender. Purpose: To investigate the relationship between BMI and indices of metabolic syndromes, as well as the predictions of BMI and waist circumference (WC) on indices of metabolic syndromes. Methods: Subjects were 68 faculty members and staffs of Chinese Culture University ( 20 male, average age 40.6 ± 10.41 yr, height: 170.1 ± 5.50 cm, weight: 74.9 ± 12.11 kg; 48 female, average age 44.6 ± 10.91 yr, height: 160.5 ± 6.35 cm, weight: 61.6 ± 9.55 kg ). Four c.c. of blood samples of each subject were drew from the antecubital vein in the morning after 12 hours of fasting. WC (through umbilicus) was measured using tape measure and blood pressure was measured using electronic sphygmomanometer. Pearson Correlation Coefficient between BMI and indicators of metabolic syndromes (WC, systolic blood pressure [SBP], diastolic blood pressure [DBP], blood glucose, triglyceride [TG] and high density lipoprotein cholesterol [HDL-C]) were calculated. Results: For male, BMI was significantly correlated with WC, SBP, DBP, TG and HDL-C (Waist: r = .917, p = .000; SBP: r = .638, p = .002; DBP: r = .456, p = .044; TG: r = .576, p = .008; HDL-C: r = -.569, p = .009). For female, BMI was significantly correlated with WC, SBP, DBP and HDL-C (Waist: r = .774, p = .000; SBP: r = .360, p = .012; DBP: r = .359, p = .012; HDL-C: r = -.370, p = .010). Conclusions: For both gender, BMI is highly related to indicators of metabolic syndromes. It is suggested that in addition to waist circumference, BMI can be used to determine obesity in metabolic syndromes.
