云南省纳西、普米、傈僳族肥胖状况分析及受试者工作特征曲线对高血压的预警作用

Analysis of obesity of Naxi,Pumi and Lisu in Yunnan Province and its warning effect on hypertension by using receiver operating characteristic curve

目的探讨云南省丽江市纳西、普米、傈僳族的肥胖流行状况和高血压的患病情况,并计算身体质量指数(BMI)、腰围、内脏脂肪等级的临界点来预警高血压,为高血压防治工作提供参考。方法选取18~90岁纳西、普米、傈僳族1471名,采用活体测量的方法对其身体形态指标进行测量,并测量血压,使用Logistic回归分析肥胖对高血压的影响,以BMI、腰围、内脏脂肪等级绘制各民族受试者工作特征(ROC)曲线。使用IBM SPSS 24.0统计学软件对数据进行处理。结果688名纳西族中肥胖108人(15.7%),腹型肥胖385人(56%),内脏脂肪超标197人(28.5%);513名普米族中肥胖46人(9%),腹型肥胖279人(54.4%),内脏脂肪超标113人(22%);270名傈僳族中肥胖率24人(8.9%),腹型肥胖121人(44.8%),内脏脂肪超标54人(20%)。3个民族肥胖、腹型肥胖、内脏脂肪超标的总体分布差异均存在统计学意义(χ^2=15.724、10.007、10.886,P<0.05)。纳西族肥胖、腹型肥胖、内脏脂肪超标率最高(P<0.05)。高血压患病601人(40.9%),腹型肥胖和内脏脂肪超标是高血压的危险因素(OR=0.676,0.456,P<0.05)。可选用BMI、腰围、内脏脂肪等级预警高血压(AUC>0.5,P<0.05)。结论纳西族、普米族和傈僳族的肥胖率等处于较高水平,可通过监测腰围和BMI来预防高血压的发病并对提早防治高血压具有重要意义。

Objective To investigate the prevalence of obesity and hypertension among the Naxi,Pumi,and Lisu ethnic groups in Lijiang City,Yunnan Province,and to calculate the cut-off points of body mass index( BMI),waist circumference,and visceral fat index to warn of hypertension,and provide a scientific reference for the prevention and treatment of hypertension. Methods We selected 1471 Naxi,Pumi,and Lisu people aged 18-90 years old,and measured their body morphological indicators by using biometric method,and measured their blood pressure. Logistic regression was used to analyze the impact of obesity on hypertension. BMI,waist circumference,and visceral fat index were used to draw the ethnic groups receiver operating characteristic( ROC) curve. Data were processed using IBM SPSS 24. 0. Results Among the 688 Naxi people,108 were obese( 15. 7%),abdominal obesity was 385( 56%),and visceral fat exceeded was197( 28. 5%);among the 513 Pumi people,46 were obese( 9%),279 were abdominal obesity( 54. 4%),and 113 were visceral fat exceeded( 22%);among the 270 Lisu people,24 were obese( 8. 9%),121 were abdominal obesity( 44. 8%),and 54 were visceral fat exceeded( 20%). The overall distribution of obesity,abdominal obesity,and visceral fat exceeded in the three ethnic groups had statistical differences( χ~2= 15. 724,10. 007,10. 886,P < 0. 05). The Naxi obesity,abdominal obesity and visceral fat index had the highest rates( P < 0. 05). There were 601 hypertension patients,prevalence was 40. 9%. Abdominal obesity and visceral fat exceeded were risk factors for hypertension( OR = 0. 676,0. 456,P < 0. 05). BMI,waist circumference and visceral fat index can be used to alert hypertension( AUC > 0. 5,P <0. 05). Conclusion The related obesity rates of the Naxi,Pumi,and Lisu ethnic groups are at a high level. Monitoring of waist circumference and BMI can prevent the onset of hypertension and is of great significance for the early prevention and treatment of hypertension.
