延边地区汉族和朝鲜族居民脂肪分布与代谢异常的关系

Relationship between the distribution of fat and metabolic abnormality in Han and Korean nationality in Yanbian area

目的:了解延边地区朝鲜族和汉族居民的脂肪分布特征及其与血压、血脂及血糖的关系。方法:于2006-08-8/17在延边地区九龙和翁声社区随机选择40～60岁朝鲜族和汉族常住居民2378名进行内脏脂肪率和体脂肪率以及血压、血脂、血糖等生化指标的检测。调查以健康体检形式进行,①内脏脂肪和体脂肪率测定采用日本TANITA株式会社生产的BC-600型体成分计测定,并且按其判定标准确定超过标准者[内脏脂肪率≥15%(男)、≥10%(女),体脂肪率(40～59岁)≥23%(男)、≥36%(女),体脂肪率(≥60岁)≥25%(男)、≥37%(女)]。②取清晨空腹(禁食12h)静脉血,采用日立-7600-010全自动生化分析仪测量血清总胆固醇、三酰甘油、高密度脂蛋白胆固醇、空腹血糖等指标。③高血压的诊断标准:收缩压≥140mmHg(1mmHg=0.133kPa)及或舒张压≥90mmHg。④血脂异常的诊断标准:总胆固醇≥5.72mmol/L,三酰甘油≥1.7mmol/L,高密度脂蛋白胆固醇<0.90mmol/L(男)、<1.0mmol/L(女)。⑤高血糖的诊断标准:空腹血糖≥6.1mmol/L。结果:①汉族男性的内脏脂肪率和体脂肪率均值分别为(10.51±3.66)%和(22.70±4.85)%,朝鲜族男性分别为(9.16±3.81)%和(20.28±5.02)%,汉族均高于朝鲜族(P<0.01);汉族女性的内脏脂肪率和体脂肪率分别为(6.22±2.27)%和(35.31±5.65)%,朝鲜族女性分别为(5.88±2.19)%和(34.00±5.72)%,汉族均高于朝鲜族(P<0.01)。②汉族男性的内脏脂肪率和体脂肪率超标率分别为12.1%和45.8%,朝鲜族男性分别为7.8%和28.6%,汉族均高于朝鲜族(P<0.05);汉族女性的内脏脂肪率和体脂肪率超标率分别为6.7%和47.9%,朝鲜族女性分别为3.8%和37.3%,汉族均高于朝鲜族(P<0.05)。③Logistic逐步回归分析结果表明,内脏脂肪率与民族、性别、年龄、高血压、高三酰甘油血症和高血糖有密切关系;体脂肪率与民族、性别、高血压、高三酰甘油血症、低高密度脂蛋白血症和高血糖有密切的关系。结论:①延边地区汉族居民内脏脂肪率和体脂肪率平均水平及其超标率明显高于朝鲜族。②内脏脂肪率和体脂肪率均与民族、性别、年龄(体脂肪率除外)、高血压、高三酰甘油血症和高血糖相关。

AIM： To analyze the relationship between the distribution of fat and blood pressure, blood fat, and plasma glucose among Han and Korean populations in Yanbian area. METHODS： This survey was carried out during August 8^th and 17^th in 2006 among 2 378 residents selected randomly from two towns of Yanbian area, where the Han and Korean residents aged 40-60 years participated in health examination. Their blood pressure, blood fat, plasma glucose, visceral fat percentage, and body fat percentage were measured.（1）BC-600 body composition detector, produced by Japan TANITA company, was used to measure and rank the visceral fat percentage and body fat percentage： Visceral fat percentage ≥ 15% （male） and ≥ 10% （female）, body fat percentage （40-59 years old） ≥ 23% （male） and ≥ 36% （female）, body fat percentage （≥ 60 years old） ≥ 25% （male） and ≥ 37% （female）.（2）Fasting venous blood was sampling in the moming for detecting total cholesterol （TC）, triacylglycerol （TG）, high-density lipoprotein cholesterol （HDLC） and fasting plasma glucose （FPG）.（3）Hypertension： blood systolic pressure ≥ 140 mm Hg （1 mm Hg=0.133 kPa） and/or diastolic pressure ≥ 90 mm Hg.（4）Lipid abnormality： TC ≥ 5.72 mmol/L, TG ≥ 1.7 mmol/L, HDLC 〈 0.90 mmol/L （male） and 〈 1.0 mmol/L （female）.（5）High plasma glucose： FPG ≥ 6.1 mmol/L. RESULTS. （1）The mean visceral fat and body fat percentages were （10.51±3.66）% and （22.70±4.85）% in the males of Han nationality, （9.16±3.81）% and （20.28±5.02） in those of Korean nationality, respectively, which were significantly higher in Han nationality than in Korean nationality （P 〈 0.01）; For female, the two targets were （6.22±2.27）% and （35.31 ±5.65） in Han, （5.88±2.19）% and （34.00±5.72）% in Korean, respectively, which were significantly higher in Han than in Korean （P〈 0.01）. （2）The prevalence rates of high visceral fat and high body fat were 12.1% and 45.8% in the males of Han, 7.8% and 28.6% in those of Korean, respectively, which were significantly higher in Han than in Korean （P 〈 0.05）; For female, the prevalence rates were 6.7% and 47.9% in Han, 3.8% and 37.3% in Korean, respectively, which were significantly higher in Han than in Korean （P 〈 0.05）.（3）The multiple Logistic regression analysis indicated that visceral fat percentage was closely related with race, sex, age, hypertension, high TG and high blood glucose; body fat percentage was closely related with race, sex, hypertension, high TG, low HDLC and high blood glucose in this area. CONCLUSION： （1）The visceral fat and body fat percentages are significantly higher in Han than in Korean nationality.（2） Both visceral fat and body fat percentages are related with race, sex, age （only visceral fat percentage）, hypertension, high TG and high blood glucose.
