OBJECTIVES: This study tried to determine human immunodeficiency virus (HIV)/sexually transmitted disease (STD) prevalences among female commercial sex workers in Mexico City. METHODS: A sampling frame was constructed that included bars, massage parlors, and street corners. RESULTS: Prevalences for Treponema pallidum, herpes simplex virus type 2, HIV, Neisseria gonorrhoeae, and Chlamydia trachomatis were 6.4%, 65%, 0.6%, 3.7%, and 11.1%, respectively. A significant association was found between higher STD frequencies and working at street sites. CONCLUSIONS: Most STD frequencies were lower in comparison with rates found for female sex workers in other countries. However, preventive programs against STD/ HIV are needed in this population.

ResumenObjetivo.Evaluar el efecto independiente de la persistencia del tabaquismo en el bajo desempeño escolar en un estudio poblacional prospectivo; para ello se utilizaron dos mediciones en un periodo de tres años aplicadas a sujetos que permanecieron en el ámbito escolar durante el lapso de seguimiento.Material y métodos. Se desarrolló un estudio de cohorte en el ámbito escolar en los periodos 1998-1999 y 2000-2001. En este artículo sólo se incluyó a 2 568 estudiantes (persistentes en el tabaquismo y no consumidores). Se construyeron modelos de regresión logística múltiple a partir de dos estratos: estudiantes con mantenimiento o mejoría del desempeño escolar e individuos con bajo rendimiento. Se consideraron dos mediciones. Se evaluó la diferencia de riesgos de persistencia del tabaquismo en función del desempeño escolar y covariables relacionadas.Resultados. En la cohorte de referencia, 5.2% de los estudiantes continuó el consumo de tabaco durante el periodo de estudio, mientras que 64.2% permaneció al margen de la exposición. El bajo desempeño escolar se vinculó con la persistencia del tabaquismo en la población total (RM= 2.27; IC95% 1.4-3.6), así como en mujeres (RM= 3.0; IC95% 1.4-6.7) y hombres (RM= 2.2; IC95% 1.1-4.1). El bajo rendimiento escolar tiene un exceso de riesgo de continuación del tabaquismo, independiente de otras covariables. La mayor diferencia en términos de prevalencia, respecto del bajo desempeño escolar, se reconoció en los sujetos con síntomas depresivos con un exceso de persistencia del tabaquismo (21.3%). Conclusiones. Deben plantearse en forma integral intervenciones que fomenten estilos
AbstractObjective. To evaluate the independent effect of poor school performance and tobacco persistence using a prospective population study of students who remained on school grounds during the follow-up period. Two measurements were taken over a period of three years. Material and methods. A cohort study conducted within school confines was developed over the period 1998 to 1999 and 2000 to 2001, with 2 568 students, including both tobacco persistent students and non-consumers. Multiple logistic regression models were designed and structured according to educational performance using two standards: students who maintained and/or improved performance and those with poor performance, based on the first and second measurements. Results. In the reference cohort, 5.2% of the students reported to have persisted with tobacco consumption during the study period, while 64.2% remained unexposed. Poor school performance was associated with tobacco persistence for the total population (OR 2.27, 95%CI 1.4-3.6), as well as for females (OR...
