Abstract
BACKGROUND: Due to the high level of sexual relationships, prostitute women are faced with many dangers, including acquired immune deficiency syndrome (AIDS), sexually transmitted infections (STIs), fertility problems, drug use, etc. In this regard, addict prostitute women are exposed to more risks because drug use is considered as an outstanding factor in those associated with transmission of AIDS and being in an insecure sexual relationship. The purpose of this study was to find out the variables influential on the level of drug use, before or during sexual relationship. METHODS: In 2010, 625 prostitute women were selected by multistage sampling from 21 centers out of 12 provinces. Then, we used a standard questionnaire for gathering data by a face-to-face interview. The multilevel ordinal logistic regression in survey model was used to find out the relationship between variables and the level of drug use before or during sexual relationship. FINDINGS: The number of monetary customers at the last working day [adjusted odds ratio (AOR): 1.87, 95% confidence interval (CI): 1.50-2.32] and having sexual relationship during the past month with monetary customers (AOR: 4.77, 95% CI: 2.61-8.70) were significantly related to the level of drug use before or during sexual relationship in the past month. CONCLUSION: Since the level of drug use before or during sexual relationship was higher in women who had more daily sexual relationships, these women are exposed to the consequences of drug use; thus, identifying the status of this group of women is important to plan for future injuries.
