社区老年居民血脂异常患病率现状及其影响因素研究

Background??Dyslipidemia is the most important and causal independent risk factor for?atherosclerotic cardiovascular diseaseASCVD. The prevalence of dyslipidemia in elderly residents in Guangdong Province is high and it is urgent to analyze the specific prevalence of dyslipidemia and its influencing factors among the elderlyand to carry out targeted preventive and control measures for dyslipidemia. Objective??To investigate the epidemiological status of dyslipidemia and its risk factors among elderly residents included in the national basic public health service in Yuexiu DistrictGuangzhou. Methods ?A total of 41 469 elderly residents aged 65 years and above with complete important variables were selected as subjects from the information system of community health service center in Yuexiu DistrictGuangzhou City in 2020the 2020 health checkup data was used to describe the epidemiological characteristics of the included patients such as basic informationBMI and blood lipid levels. Restricted cubic splineRCS fitting Logistic regression model was used to analyze the relationship between ageBMI and the prevalence of dyslipidemia. Results??The prevalence of dyslipidemia in 41 469 elderly residents was 53.65%22 247/41 469with a standardized prevalence of 53.89%. The prevalence of hypercholesterolemiaHTChypertriglyceridemiaHTG mixed hyperlipidemia and low high-density lipoprotein cholesterol was 21.43%16.50%14.51% and 3.80%with the standardized prevalence of 21.57%16.53%14.61%3.78%respectively. Multivariate Logistic regression analysis showed that genderageeducation levelexercise statusand BMI were all influencing factors for dyslipidemia in elderly residentsamong which femalelow age groupand high BMI were risk factors for dyslipidemia in elderly residentsP<0.05. The results of RCS fitting showed a non-linear relationship between ageBMI and the prevalence of dyslipidemia in elderly residents. The overall prevalence of dyslipidemia in elderly residents showed a decreasing trend with the increase of age. The risk of dyslipidemia showed a increasing and then decreasing trend with the increase of BMIthe OR?increased significantly at low BMIwhile decreased at high BMI. Conclusion??The prevalence of dyslipidemia is relative high among elderly residents aged 65 years and above included in the national basic public health services in Yuexiu DistrictGuangzhou. The prevalence of dyslipidemia in the elderly group tends to decrease with the increase of ageand the risk of dyslipidemia prevalence tends to increase and then decrease with the increase of BMIsuggesting special features in the management of dyslipidemia among the elderlythe analysis of risk factors for dyslipidemia in the elderly should be focused on and early preventive and control measures should be carried out.
