Abstract:
Objective:To investigate the detection rate of nonalcoholic fatty liver disease(NAFLD)and its influencing factors among residents in western Chongqing of China during physical examination.Methods:Based on the clinical diagnostic criteria and ultra-sound examination results of NAFLD,the individuals who underwent physical examination in a grade A tertiary hospital in Western Chongqing from January 1,2020 to November 30,2023 were enrolled as subjects.The methods such as the t-test,the chi-square test,and the multivariate logistic regression analysis were used to clarify the detection rate of NAFLD and its influencing factors among the individuals undergoing physical examination.Results:The detection rate of NAFLD was 23.64%(12 872/54 067)among the individu-als undergoing physical examination.The detection rate of NAFLD in male individuals was significantly higher than that in female indi-viduals(39.22%vs.15.91%,χ2=2 197.112,P<0.001).The individuals in the age group of 50-59 years had the highest NAFLD detec-tion rate of 33.18%,and before the age of 60 years,the detection rate of NAFLD increased with age,while after the age of 60 years,the detection rate of NAFLD decreased with age(χ2=367.554,P<0.001),indicating the detection of NAFLD in younger populations in western Chongqing.The individuals with a body mass index in-dicative of overweight and obesity had a significantly higher detec-tion rate of NAFLD than those with a body mass index indicative of emaciation and normal weight(39.39%/71.40%vs.0.23%/9.68%,χ2=7 644.383,P<0.001).The multivariate logistic regression analy-sis showed that sex,age,body mass index,fasting blood glucose(FBG),systolic blood pressure(SBP),diastolic blood pressure(DBP),triglyceride(TG),uric acid(UA),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C)were risk factors for the detection rate of NAFLD in individuals undergoing physical examination(P<0.05),while total cholesterol(TC)was not a risk factor for the detection rate of NAFLD.Conclusion:The detection rate of NAFLD is 23.64%among the individuals aged 18 years or above who undergo physical examination in Western Chongqing,and there is a relatively high incidence rate of NAFLD in the age group of 50-59 years.Male individuals and overweight or obese individuals are at a high risk of NAFLD.FBG,SBP,DBP,TG,UA,HDL-C,and LDL-C are risk factors for NAFLD,while TC is not a risk factor for NAFLD.
