BackgroundPerceived beliefs about breast cancer and breast cancer screening are important predictors for mammography utilization. This study adapted and validated the Champion's scale in Peru. This scale measures perceived susceptibility for breast cancer and perceived benefits and barriers for mammography.MethodsA cross-sectional study was conducted among women ages 40 to 65 attending outpatient gynecology services in a public hospital in Peru. A group of experts developed and pre-tested a Spanish version of the Champion's scale to assess its comprehensibility (N = 20). Factor analysis, internal consistency, and test-retest reliability analyses were performed (N = 285). Concurrent validity compared scores from participants who had a mammogram and those who did not have it in the previous 15 months. T-test and multiple regression analysis adjusting for socio-demographic factors, mammography knowledge and other preventive behaviors were performed.ResultsThe construct validity and reliability were optimal. Cronbach-Alpha coefficients were 0.75 (susceptibility), 0.72 (benefits) and 0.86 (barriers). Concurrent validity analysis showed an association between barriers and mammography screening use in bivariate (22.3 ± 6.7 vs. 30.2 ± 7.6; p < 0.001) and multiple regression analysis (OR = 0.28, 95% CI = 0.18-0.43). Ages 50-60 years (OR = 2.35, 95% CI = 1.19-4.65), history of prior Papanicolaou test (OR = 3.69, 95% CI = 1.84-7.40), and knowledge about breast cancer and mammography (OR = 3.69, 95% CI = 1.84-7.40) were also independently associated with mammography screening use.ConclusionConcurrent validity analysis showed that the Champion's scale has important limitations for assessing perceived susceptibility for breast cancer and perceived benefits for mammography among Peruvian women. There is still a need for developing valid and reliable instruments for measuring perceived beliefs about breast cancer and mammography screening among Peruvian women.
El presente trabajo se realizó en el Centro de Fertilidad del Hospital Arzobispo Loayza, abarcando 3,600 pacientes desde el año 1955 a 1977. Se seleccionó 1,707 que completaron su estudio.
Estas dos técnicas que llevan los nombres de sus autores, son las más conocidas de todas las técnicas de colposuspensión suprapúbica que son utilizadas con mayor frecuencia aquí y en otros lugares del mundo1-5; incluso la técnica de Burch ha sido empleada en la cirugía laparoscópica6,7. El presente estudio tiene por objeto la comparación de ambas en la cirugía convencional a cielo abierto para apreciar la existencia de alguna ventaja de una técnica sobre la otra en la incontinencia urinaria de esfuerzo (IUE).
OBJETIVO: Evaluar los resultados de la administración de tibolona como terapia de reemplazo hormonal en perimenopáusicas que aún presentan sangrado uterino. Diseño: Estudio observacional clínico. MATERIAL Y MÉTODOS: Cincuenta mujeres perimenopáusicas con FSH sérico mayor de 40 UI/mL y ausencia de patología ginecológica, a quienes se administró tratamiento combinado de tibolona y píldoras anticonceptivas, con el fin de abatir el endometrio, para luego prescribir tibolona sola. RESULTADOS: El 50% de las pacientes estudiadas respondió satisfactoriamente a este esquema terapéutico. CONCLUSIÓN: El esquema terapéutico combinado de tibolona y píldoras anticonceptivas puede lograr la amenorrea en un grupo de mujeres perimenopáusicas.
