目的了解贺州市吸毒人群艾滋病感染状况及高危行为状况变化趋势,评价该地区近年对吸毒人群的干预效果。方法采用SPSS11.5统计软件对2005—2008年贺州市吸毒人群艾滋病哨点监测数据进行统计分析。结果吸毒人群中艾滋病病毒抗体(HIV抗体)阳性率为33.66%,艾滋病感染率呈现逐年递减趋势(χ2=33.16,P<0.01);注射吸毒比例呈逐年下降趋势,且差异有统计学意义(χ2=18.54,P<0.01),注射吸毒且共用针具者与注射吸毒但不共用针具者艾滋病感染状况差异有统计学意义(χ2=17.46,P<0.01)。通过钱或毒品交易与他人发生过性行为的占30.16%,在这些性行为中每次均使用安全套的比例相当低,仅为16.80%,而从不使用安全套比例高达52.00%。结论该市吸毒人群中艾滋病流行严峻,近年来,该市开展了大量针对吸毒人群的宣传教育和行为干预工作,并且取得了一定成效,但仍须进一步加强,不断降低吸毒人群HIV感染率。
Objective To understand the changing trend of HIV status and high-risk behaviors among drug users in Hezhou and to evaluate the effect of drug intervention in this area in recent years. Methods SPSS11.5 statistical software was used to analyze the sentinel surveillance data of AIDS among drug users in Hezhou City during 2005-2008. Results The positive rate of HIV antibody (HIV antibody) among drug users was 33.66%, and the rate of HIV infection showed a year by year decreasing trend (χ2 = 33.16, P <0.01). The proportion of injecting drug use showed a declining trend year by year with a significant difference (χ2 = = 18.54, P <0.01). There was significant difference in HIV infection status between injecting drug users who shared needles and injecting drug users but not sharing needles (χ2 = 17.46, P <0.01). The share of condom use in each of these sexes, which accounted for 30.16% of those who had sex with others through money or drug trafficking, was rather low at 16.80% and never used condoms as high as 52.00%. Conclusion The HIV / AIDS epidemic among drug users in this city is severe. In recent years, the city has conducted a large number of publicity and education and behavioral interventions aimed at drug addicts and has achieved some success. However, it still needs to be further strengthened to reduce the HIV infection rate among drug users.
