| ObjectiveTo found an intervention model fit for this locality according to the requisition of thefifth global foundation of AIDS projects in China. We evaluate the available interventionmodel through field investigation and based on the mobile population’s knowledge of AIDS,attitude and behavior, which is expected to elevate the function of intervention study in AIDSof mobile populations.MethodsCommunity modeling: according to the prevention and control system organized bygovernment, responsible by relevant departments and attended by the whole society, and themode theory and frame proposed by the fifth global foundation of AIDS projects, to build upthe mobile population intervention model based on communities. The core of the model is toevolve persistence intervention practice with the feature of different categories of mobilepopulation. The objective is to elevate the AIDS knowledge in crowd and to promote changeof high-risk behaviors.Intervention model evaluation: to adopt field investigation with quantitative combinedwith qualitative investigations. First of all, we use the method of hierarchy cluster sampling tochoose the mobile population sample in areas intervened from2006to2010for questionnaireinvestigation, and analyze the feature of society demography, AIDS knowledge, attitude,behaviors and the information and changing tendency of HIV infection; further to undertakethe special group discussion and personal face-to-face semi-structured interview throughqualitative investigation to know and understand causes and motivations of knowledge,attitude and behaviors of the mobile population, as well as the main experience andinfluencing factors in implementing the intervention model. Results1. The mobile population in Jiulongpo District of Chongqing mainly consists ofconstruction workers, workers in the tertiary industry, employed labors and individuals; due tofactors including the large number and low education level of such people, lacking knowledgeof AIDS, high-risk sexual behaviors and shortage of an administration department, greatdifficulty is resulted in for prevention and control of AIDS;2. In the five streets and towns with concentrated mobile population, an interventionmodel based on communities is established and improved, and a basic team comprising over200people has been formed and well trained; the mobile population is divided into four subcategories for daily supervision and management by specified department or unit, and nearly1500intervention activities have been carried out; critical points and links of intervention fordifferent sub categories of mobile population have been summarized based on the in-situexperiences;3. According to quantitative investigation, the acquaintance rate of AIDS knowledge bythe mobile population receiving long-term intervention gradually rose from37.7%in2006to67.3%in2010; the discrimination attitude tends to grow more intense. The quantitativeinvestigation also showed that the model has been well received by the mobile population.The undertaking and task have not only gone deep into the communities based on the need butalso are designated proportionally to different health departments, which makes theintervention more feasible.4. Based on the growing acquaintance rate of AIDS knowledge, there is no obviouseffect on change of dangerous behaviors resulting in AIDS, mainly reflected by a trend ofdecreasing commercial sexual behaviors among the mobile population; however, relevantbehaviors are greatly affected by individual psychology and social support, and are liable tostimulation; additionally, the proportion of sexual behaviors persisting in using condomsfluctuates between25%and49%; irregular sexual disease treatments still exist.Conclusions1. For the individual and collective features of mobile population, it is hard to carry outprevention and control of AIDS among such people. Jiulongpo District has established acomprehensive mode for AIDS intervention among mobile people, which is guided by thegovernment and furthered deep into communities with sorted administration of the mobilepopulation, and has made certain achievements in AIDS intervention among population of different categories. Through such a mode, the administration functions of the health andsanitary management technical force, including support, supervision, training and evaluation,are also fully exerted in comprehensive intervention;2. The intervention mode obviously promotes the acquaintance rate of AIDS knowledgeamong the mobile population, but there are still problems. In future, the intervention coverageshall be further enlarged, comprehensive social support to the mobile people shall bestrengthened, and further studies shall be carried out regarding psychology and behaviors. |
