[Changes in condom use among a cohort of prostitutes].
OBJECTIVE
To describe changes in condom use among prostitutes enrolled in a prospective cohort study in Alicante (Spain), and to identify those factors associated with changes in this behaviour.


METHODS
Data from this study come from a prospective cohort study of women working at prostitution enrolled in a center for AIDS preventive at Alicante from 1986 to 1996. The proportion of condom use by prostitutes with their clients was recorded during the first visit and the last one, and changes in condom use were estimated as the difference between them. Two logistic regression analyses were done to identify those factors associated with positive or negative changes in condom use.


RESULTS
A statistically significant increase in the prevalence of condom use was observed between the first, 69,2%, and the last visit, 83,9% (p < 0,001). Prostitutes working private increased the condom use more than five time than those working in clubs or at the street. The higher the follow-up time the higher the prevalence of condom user, OR > 6 years = 7,6 (95% CI: 2,2-26,0). No variable was associated with a negative change in condom use.


CONCLUSIONS
This study shows an overall increase of condom use in a cohort of prostitutes after 10 years of follow-up. Relapse in risk behavior has been infrequent. In the future, preventive strategies to increase the use of condoms among prostitutes should be adapted to the new forms of sexual commerce.
