The investigation content include AIDS-related knowledgespread, self-efficacy level and state of condom use. Comprehensive intervention fora period of four months was conducted at all above entertainment places after thebaseline survey. And the post-intervention survey for AIDS-related knowledgespread and state of condom use was done, using the same questionnaire, one monthlater after the intervention.418and461valid questionnaires were collectedrespectively by baseline and interventional survey. Database was set up based onEpiData3.1, and the data was analyzed by using SPSS13.0.Results1. Studies have shown that:1/the female sex workers in LinHai are generallyyoung, with55.50%below25years old;2/they are less educated, with69.38%havejunior high school diploma or below;3/51.67%of them were never got married;4/81.82%population from22provinces (municipalities and autonomous regions);5/44.74%had been working in Linhai for less than6months.2. The baseline results showed that AIDS-related knowledge awareness rate infemale sex workers is77.51%. The difference of awareness rate between differententertainment places is of statistical significance(χ~2=14.480，P=0.001), among whichthe low-grade places are of the highest awareness rate. Using demographic data, type of working place, state of AIDS service receiving as argument, awareness ofAIDS-related knowledge as dependent variable, and introducing logistic regressionmodel, to establish regression model including three factors of AIDS prevencepublicizing, edge and type of working place. Subjects scored at84.83±10.89incondom use self-efficacy evaluation. Subjects at different places scoreddifferently(F=19.722，P＜0.001), and the highest score is in the low grade places.Acrodding analyse of multiple stepwise regression the main influence of condomuse self-efficacy level were place type, AIDS-related knowledge and education ofsexual partners. The rate of condom use among female sex workers in their lastsexual behavior was41.6%, the main reason for female sex workers not to usecondoms is their sexual partners’ reluctance. Only16.7%female sex workers usecondoms in every sexual intercourse last month. The difference of condom use ratein different types of entertainment places is of statistical significance(χ~2=78.482，P＜0.001), among which the low-grade places are of the highest condom use rate.Using logistic regression analyse the influence factors of condom use, and resultsshowed that condom use self-efficacy condoms-use publicizing, AIDS counseling,working time and place type are factors that affect the level of knowledge ofAIDS.The proportion of peer education in low-grade places is higher than that inmedium and high-grade places(χ~2=3.854，P=0.050). The laboratory testing resultsshow that the proportion of female sex workers in different types of places infectedwith syphilis (ELISA positive) is not all the same, but there is no significantdifference between the proportions of newly infected people (RPR positive) indifferent types of places（χ~2=4.413，P=0.110）.3. After the intervention, the awareness rate of AIDS-related knowledgeincreased to89.15%. The difference in the before and after intervention is ofstatistical significanc（eχ~2=21.691，P﹤0.001）, while the difference of awareness rateat different places after intervention is of no statistical significance（χ~2=5.600，P=0.061）.29.07%female sex workers use condoms in every sexual intercourse lastmonth, which is of statistical significance（χ~2=18.637，P＜0.001）compared with thatbefore intervention. The difference in condom use between different types of placesafter intervention is of statistical significanc（eH=38.724，P＜0.001）. The differencesof the condom use before and after intervention at high and medium-gradeentertainment places are of statistical significance（Z=-3.260，P=0.001；Z=-5.164，P＜0.001）, while it is of no statistical significance for that at low-gradeentertainment places（Z=-0.123，P=0.902）.. Conclusions1. The Linhai female sex workers whose AIDS-related knowledge is limitedand rate of condom use is low are the high-risk groups for AIDS and other venerealdiseases infection and transmission.2. The first reason for the female sex workers without using condom of therecent sec instant acts were there persuading sexual partners’imparities, theinfluencing factors of using condom were subjects’ self-efficacy level, drumbeatingof AIDS preventing, working time at native place and type of working place.3.
