目的了解新疆博尔塔拉州(博州)维吾尔族(维)、哈萨克族(哈)、蒙古族(蒙)、汉族人群超重肥胖与血压水平的相关性。方法 2004-09-10采用分层随机整群抽样法完成的新疆博州维、哈、蒙、汉族人群的代谢综合征流行病学资料中≥30岁并资料完整的3935人作为研究对象。通过相关及回归分析4个民族体质量指数(BMI)、腰围水平及超重肥胖和血压的关系。结果多因素线性回归分析控制年龄、性别、受教育程度、职业及饮酒因素后,BMI(18.5～23.9、24.0～27.9、≥28.0kg/m2)每增加一级,4个民族的收缩压增加6.4(维)、7.4(哈)、4.5(蒙)、6.2mmHg(汉),舒张压增加4.0(维)、5.6(哈)、3.5(蒙)、4.6mmHg(汉);腰围水平[<85(男),80cm(女)、85～94(男),80～89cm(女)、≥95(男),90cm(女)]每增加一级,4个民族的收缩压增加6.4(维)、6.4(哈)、6.3(蒙)、5.8mmHg(汉),舒张压增加4.3(维)、5.0(哈)、4.0(蒙)、3.1mmHg(汉)(均P<0.01)。和正常体质量或腰围比,发生肥胖或腹型肥胖4个民族患高血压的风险是3.6(维)、4.2(哈)、2.7(蒙)、3.5(汉)倍。BMI每增加一级,收缩压增加幅度相对最小的是蒙族(4.5mmHg)、哈族相对最大(7.4mmHg),而且和正常体质量比,肥胖时患高收缩压的风险蒙族是2.3倍、哈族是3.6倍。和BMI增加相比,腰围每增加一级收缩压增高幅度相对较大的是蒙族(6.3mmHg),且腹型肥胖时患高收缩压的风险(3.7倍)明显高于肥胖时患高收缩压的风险(2.3倍)。结论 BMI和腰围水平增加是新疆博州维、哈、蒙、汉族人群血压升高较好的临床预测指标,但发生肥胖或腹型肥胖时哈族人群患高血压的风险相对最大,腰围增加或腹型肥胖能较BMI更好的预测蒙族人群的收缩压增加。
Objective To investigate the relationship between overweight and obesity and blood pressure in Uygur (Kazak), Kazak (Ha), Mongolian (Mongol) and Han nationalities in Bortala Prefecture, Bohai Autonomous Region. Methods A total of 3935 persons aged 30 years and over from the epidemiological data of metabolic syndrome in the population of Victoria, Ha, Mongolian and Han nationalities in Xinjiang, which were completed by stratified random cluster sampling method, were selected as the research object. Correlation and regression analysis of the four national mass index (BMI), waist circumference and obesity and blood pressure. Results Multivariate linear regression analysis showed that the systolic blood pressure of four ethnic groups increased 6.4% for each level of BMI (18.5-23.9,24.0-27.9, ≥28.0kg / m2) after controlling for age, gender, education level, occupational and alcohol consumption Diastolic blood pressure increased by 4.0 (Victoria), 7.4 (Ha), 4.5 (Mongolian), 6.2 mmHg (Han) For each additional level, the systolic blood pressure of the four ethnic groups increased by 6.4 (V), while the systolic blood pressure increased by 80% (female), 85-94 (male), 80-89 cm (female), ≥95 (male), and 90 cm The mean increase of diastolic blood pressure was 6.4 (ha), 6.3 (m), 5.8mmHg (diastolic), diastolic blood pressure 4.3 (d), 5.0 (ha), 4.0 (mm), 3.1mmHg (all p <0.01). And the normal body mass or waist circumference, obesity or abdominal obesity in the four ethnic groups suffering from hypertension are 3.6 (Victoria), 4.2 (Ha), 2.7 (Mongolia), 3.5 (Han) times. For each additional level of BMI, the relative increase in systolic blood pressure was the lowest in the Mongolian (4.5 mmHg) and the highest in the Kazakh (7.4 mmHg), and 2.3 times higher than the normal body mass ratio Family is 3.6 times. Compared with the increase of BMI, the increase of waist-circumference systolic blood pressure by one grade of relative increase was that of Mongolian (6.3 mmHg), and the risk of high systolic blood pressure (3.7 times) in abdominal obesity was significantly higher than that of obesity The risk (2.3 times). Conclusions The increase of BMI and waist circumference is a good predictor of hypertension in Bo, Uygur, Han and Han nationalities in Xinjiang, but the risk of hypertension is higher in Kazakhs with obesity or abdominal obesity. The waist circumference is increased or Abdominal obesity better than the BMI prediction of Mongolian systolic blood pressure increased.
