摘　　要：目的:调查视力残疾职校生血脂健康状态,探讨人体测量指标(BMI和腰围)和超声评估指标(肝肾回声比值、皮下脂肪厚度及内脏脂肪厚度)与血脂异常的关系。方法:纳入66例视力残疾职校生,分析人体测量指标、超声脂肪评估指标与血脂之间的相关性;比较人体测量指标和超声评估指标在血脂异常和正常学生间的差异。结果:66例中,血脂异常检出率27.3%(18/66)。人体测量指标及超声评估指标均与血脂有较好的相关性(r=0.35~0.64,均P<0.05)。血脂异常学生的年龄、BMI、脂肪肝比例、腰围、肝肾回声比值、皮下及内脏脂肪厚度均高于血脂正常学生,且视力残疾程度更严重(均P<0.05)。肝肾回声比值(OR=46.6,P=0.01)和年龄(OR=1.3,P=0.02)是血脂异常的危险因素,两者联合诊断血脂异常的AUC为0.88(95%CI0.74~0.96),敏感度和特异度分别为100.0%和68.9%。肝肾回声比值联合年龄预测血脂异常的AUC显著高于单独使用腰围、BMI、内脏脂肪厚度及皮下脂肪厚度(Z=2.45~4.13,均P<0.05)。结论:该校视力残疾学生血脂异常检出率较高,超声评估指标及人体测量指标与血脂密切相关,且年龄联合肝肾回声比值能更好地预测血脂异常。Objective:To investigate the lipid health status of students in a vocational school,and to analyze the relationship between body fat measurements(BMI,waist circumference)and ultrasound assessment indices(hepatorenal echo ratio,subcutaneous and visceral fat thickness)and dyslipidemia.Methods:A total of 66 visually impaired students were enrolled.The correlations between BMI,waist circumference,hepatorenal echo ratio,subcutaneous fat thickness,visceral fat thickness and their blood lipids were analyzed.And the differences in the above parameters between dyslipidemia students and students with normal blood lipids were compared.Results:In 66 cases,18 cases had dyslipidemia(27.3%).Both the body fat measurements and the ultrasound assessment indices had good correlations with blood lipids(r=0.35—0.64,all P<0.05).The age,BMI,fatty liver proportion,waist circumference,hepatorenal echo ratio,subcutaneous and visceral fat thickness in dyslipidemia students were significantly higher than those in students with normal blood lipids(all P<0.05).Both the hepatorenal echo ratio(OR=46.6,P=0.01)and age(OR=1.3,P=0.02)were risk factors for dyslipidemia,and the combination of the two parameters predicted the dyslipidemia with an AUC of 0.88(95%CI 0.74—0.96),with a sensitivity and specificity of 100.0%and 68.9%,respectively.The AUC was significantly higher than using waist circumference,BMI,visceral fat thickness,and subcutaneous fat thickness individually(Z=2.45—4.13,all P<0.05).Conclusions:The percentage of dyslipidemia is high in visually impaired students in the vocational school.Both the body fat measurements and the ultrasound assessment indices have correlations with dyslipidemia,and the combination of hepatorenal echo ratio and age could effectively predict dyslipidemia.
