ABSTRACT
OBJECTIVE: To identify factors that are associated with an increased risk of developing high-grade cervical intraepithelial neoplasia (CIN) or cancer among human papillomavirus (HPV)-positive women in Mexico. MATERIAL AND METHODS: A case-control study design was used. A total of 94 cases and 501 controls who met the study inclusion criteria were selected from the 7 732 women who participated in the Morelos HPV Study from May 1999 to June 2000. Risk factor information was obtained from interviews and from HPV viral load results. Odds ratios and 95 percent confidence intervals were estimated using unconditional multivariate regression. RESULTS: Increasing age, high viral load, a young age at first sexual intercourse, and a low socio-economic status are associated with an increased risk of disease among HPV-positive women. CONCLUSIONS: These results could have important implications for future screening activities in Mexico and other low resource countries.
RESUMEN
OBJETIVO: Identificar factores asociados con un mayor riesgo de desarrollar neoplasia intraepitelial cervical (NIC) de alto grado o cáncer en mujeres con virus de papiloma humano (VPH), en México. MATERIAL Y MÉTODOS: Se utilizó un diseño de casos y controles. Un total de 94 casos y 501 controles fueron seleccionados de las 7 732 mujeres que participaron en el Estudio de VPH en Morelos, de mayo de 1999 a junio de 2000. La información sobre factores de riesgo se obtuvo de entrevistas y de los resultados de carga virales de VPH. Se estimaron razones de momios e intervalos de confianza de 95 por ciento con modelos multivariados de regresión no condicionada. RESULTADOS: El incremento de edad, la carga viral elevada, la edad temprana al inicio de la vida sexual y el nivel socioeconómico bajo se asocian con un mayor riesgo de enfermedad en mujeres VPH positivas. CONCLUSIONES: Estos resultados podrían tener implicaciones importantes a futuro para las actividades de tamizaje en México y en otros países de bajos recursos.
