目的回顾性分析重庆市2006-2012年艾滋病防控工作开展及效果,探索HIV/AIDS在重庆地区的时空聚集性。方法从重庆市38个区县的传染病上报系统和哨点监测数据库中,收集重庆市38个区县从2006年到2012年的HIV/AIDS疫情统计数据和艾滋病防控经济指标。采用Person相关系数进行线性趋势检验,分析指标间的相关性。采用Satscan软件对HIV携带者数进行时空聚集性分析。结果 2006-2012年重庆市男男性行为者、注射吸毒者和暗娼人群的HIV感染率分别为15.62%(95%CI:14.41%~16.86%)、8.42%(95%CI:7.82%~9.03%)和0.18%(95%CI:0.10%~0.25%)。同期重庆市艾滋病防控总投入、接受咨询和检测的人数和注射吸毒人群人均干预人次数均呈现增长趋势(均有P<0.05),但高危人群安全套使用率并未呈现增长趋势(均有P>0.05),高危人群HIV感染率未呈现下降趋势(均有P>0.05)。HIV携带者数主要聚集区在中西部和中南部的区县,时间聚集在2010-2012年。结论虽然重庆市2006-2012年对于艾滋病高危人群的艾滋病预防控制工作得到了开展,但高危人群的安全性行为没有得到加强,HIV的感染率没有下降,防控效果不理想。HIV/AIDS的流行呈现时空聚集性,空间聚集区为中西部和中南部的区县,并随时间呈现上升趋势。
Objective To retrospectively analyze the development and effect of AIDS prevention and control in Chongqing from 2006 to 2012 and to explore the space-time aggregation of HIV / AIDS in Chongqing. Methods The HIV / AIDS epidemic statistics and AIDS prevention and control economic indicators of 38 districts and counties in Chongqing from 2006 to 2012 were collected from infectious disease reporting system and sentinel surveillance database of 38 districts and counties in Chongqing. Person correlation coefficient was used to test the linear trend, and the correlation between the indexes was analyzed. Spatiotemporal clustering analysis of HIV carriers using Satscan software. Results The HIV prevalence of MSM, injecting drug users and female sex workers in Chongqing from 2006 to 2012 were 15.62% (95% CI: 14.41% ~ 16.86%), 8.42% (95% CI: 7.82% ~ 9.03% ) And 0.18% (95% CI: 0.10% -0.25%). Over the same period, the total investment in AIDS prevention and control, the number of people receiving counseling and testing, and the number of per capita interventions among injecting drug users in Chongqing showed an increasing trend (both P <0.05), but there was no increase in the rate of condom use in high-risk groups > 0.05), HIV prevalence in high-risk groups did not show a downward trend (both P> 0.05). The number of HIV carriers is mainly concentrated in the central and western and central and southern counties and counties, the time gathered in 2010-2012. Conclusions Although prevention and control of HIV / AIDS in Chongqing from 2006 to 2012 have been carried out, the safety behaviors of high-risk population have not been strengthened, the HIV infection rate has not declined, and the prevention and control effects have not been satisfactory. The prevalence of HIV / AIDS showed spatiotemporal aggregation. The spatial agglomeration area was a counties and counties in the central, western and central south China, and showed an upward trend over time.
