摘要
目的了解成都市艾滋病流行状况,分析流行特点并进行空间聚类,为制定防治措施提供科学依据。方法对成都市2015-2018年艾滋病流行特点进行描述和分析,同时引入不同区(市)县的2015-2018年艾滋病累计报告病例数和新报告病例年均增长率、医疗卫生综合得分等9个变量,对该市的20个区(市)县进行聚类。结果成都市2015-2018年新报告艾滋病病毒(HIV)感染者/艾滋病(AIDS)病人年均增长率为11.56%,其中50岁以上的病例占比从2015年的35.33%增加到2018年的51.38%,男性占79.71%,异性性传播占比从2015年的69.38%增加到2018年的80.90%;引入9个变量将该市20个区(市)县划分为4个亚流行区。结论成都市艾滋病疫情呈上升趋势,且呈老龄化趋势,不同流行亚区需采取针对性的防治措施。
Objective To understand the HIV/AIDS epidemic situation in Chengdu,by hierarchical clustering analysis so as to provide the scientific basis for developing the prevention measures.Methods The data of HIV/AIDS epidemic situation during 2015-2018 were described and analyzed,and nine variables including the cumulative number of AIDS cases reported in different areas,the average annual growth rate of newly reported cases,and the comprehensive medical and health scores were introduced for the hierarchical clustering analysis.Results The average annual growth rate of the AIDS cases newly reported in Chengdu from 2015 to 2018 was 11.56%,among which the rate of cases over the age of 50 years increased from 35.33%in 2015 to 51.38%in 2018,and 79.71%were males,with the proportion of heterosexual transmission increasing from 69.38%in 2015 to 80.90%in 2018,based on the analysis of the nine variables introduced to divide the areas into four epidemic parts with the characteristics.Conclusion The HIV/AIDS epidemic in Chengdu is rising,esp.in the group of the aged group.Specific prevention and control measures should be taken in different epidemic areas.
