Objective To investigate the level of unsafe sexual behavior of construction workers and its influencing factors in Huangpu District, and to provide a theoretical basis for comprehensive control of HIV/AIDS.
Methods Construction workers of 6 construction sites were chosen by cluster sampling to be surveyed by questionnaire, which included general information, age of first sex, knowledge of venereal diseases and AIDS, sex attitudes and situation of condom use. Blood and urine samples were collected and inspected, and SPSS 17.0 was used to perform single factor and multiple factors logistic regression analyses.

Among them, the rate of premarital sex was 26.8%, the rate of extramarital sex was 10.2%, the rate of having commercial sex was 5.7% and the rate of having multiple sexual partners was 6.7%. Analyzed by binary logistic regression, unsafe sexual behaviors were related to 6 factors:those who had higher education, those whose age of first sex was younger, those who had higher monthly wage, those who had higher knowledge score about AIDS, the unmarried, the divorced, and the widowed were more likely to have unsafe sexual behaviors. The detection rate of syphilis was 1.5%, that of gonorrhea was 4.4%, and that of Chlamydia Trachomatis was 0.8%.
Conclusion The rate of unsafe sexual behavior was high and the self-protective and risk consciousness was low among construction workers, so effective intervention should be carried out urgently.
