Mammography Stages Adoption and Health Beliefs in Mexican Women / Etapas de Cambio en el Uso de la Mamografía y Creencias de Salud en Mujeres Mexicanas

Abstract Objective. To identify associations between sociodemographic variables and stages of change and evaluate differences between health belief model variables and these stages. Methods. This cross-sectional descriptive study included 612 women aged 40 years and older admitted to a public hospital in the Northeast of Mexico. The participants answered the health belief model scale and selected the statement that best reflected their experience with mammography screening. The association between sociodemographic and clinical variables and the mammography stages of change was assessed using X2, and the groups of stages of change were compared using one-way ANOVA and Games-Howell post-hoc tests. Results. There was a significant association between age and the stages of action and maintenance. Breast cancer screening methods such as breast self-examination and clinical breast examination were more common among women in the stages of maintenance and relapse. There were differences between pre-contemplation and the more advanced stages in all dimensions except in the perceived seriousness p <.001. Self-efficacy and health motivation were different among women at the stage of contemplation, maintenance, and relapse. Conclusions. Perceived self-efficacy and health motivation may increase adherence to mammography screening.

Resumen El objetivo de la investigación fue identificar la asociación entre las variables sociodemográficas y las etapas de cambio para el uso de la mamografía y evaluar si existen diferencias entre las dimensiones del modelo de creencias en salud y las etapas de cambio. El diseño de este estudio es transversal descriptivo, se realizó de enero de 2017 a enero de 2018, incluyó a 612 mujeres de 40 años en adelante que asistían a un hospital de atención terciaria en el noreste de México. Las participantes firmaron el consentimiento informado y respondieron a la escala del modelo de creencias en salud y seleccionaron la declaración que mejor reflejaba su experiencia con la mamografía. La asociación entre las variables sociodemográficas y clínicas y las etapas de cambio de la mamografía se evaluó mediante X2, y los grupos de etapas de cambio se compararon mediante pruebas post hoc de ANOVA unidireccional y Games-Howell. Se encontró una asociación significativa entre la edad y las etapas de cambio de acción y mantenimiento. Los métodos de detección del cáncer de mama, como la autoexploración de mama y el examen clínico de mama, fueron más comunes entre las mujeres en las etapas de mantenimiento y recaída. Se obtuvieron diferencias significativas entre las etapas de pre-contemplación y las etapas más avanzadas en todas las dimensiones de creencias de salud, excepto en la seriedad percibida p <.001. La autoeficacia y la motivación para la salud fueron diferentes entre las mujeres en la etapa de contemplación, mantenimiento y recaída. La identificación de las etapas de cambio para la adopción de mamografías puede ayudar a desarrollar e implementar estrategias de intervención más efectivas. Además, la autoeficacia percibida y la motivación para la salud pueden aumentar la adherencia a la mamografía como método de detección del cáncer de mama.

Moderate-intensity physical activity ameliorates the breast cancer risk in diabetic women.

OBJECTIVE: To evaluate the association between self-reported diabetes and the risk of breast cancer (BC) and its interaction with moderate-intensity physical activity in pre- and postmenopausal Mexican women. RESEARCH DESIGN AND METHODS: A population-based case-control study was conducted using 1,000 incident case subjects and 1,074 control subjects. Blood samples and information on health, diet, physical activity, and anthropometric measurements were obtained. RESULTS: The association between diabetes and BC risk decreased with increasing tertiles of moderate-intensity physical activity (odds ratio [OR] = 4.9 [95% CI 2.3-10.8]; 3.0 [1.3-6.9]; and 1.0 [0.1-9.2], respectively, for each tertile) (test for interaction = 0.04). Compared with the women in the lowest tertiles, increased risk was observed in those premenopausal women with the highest serum C-peptide, IGF-1, and IGF-1 binding protein 3 levels. CONCLUSIONS: Moderate-intensity physical activity can substantially ameliorate the increased BC risk in diabetic women.

[Clinical experience of early percutaneous drainage of amebic hepatic abscess]. / Experiencia clínica con la punción temprana del absceso hepático amebiano.

BACKGROUND: Amebic hepatic abscesses are a frequent illness in Mexico, where these are different from those of the rest of the world. The treatment that we use should also be different. We propose new indications for percutaneous drainage in this pathology. In our hospital we found a high incidence in laparotomies, morbidity and lengthy hospitalization for this illness. METHODS: We studied 29 cases of hepatic abscesses treated at our hospital from January 2002 to May 2004. Patients received the conventional treatment and we compared this group with another group of 22 patients who had drainage before 48 h of hospitalization, during the period from June 2004 to August 2005. RESULTS: Both groups showed similar characteristics. The first group was drained only in 13.79% of cases, the second in 100%. In the first group, 44.82% had surgery and in the second group 4.5% had surgery. Length of hospitalization in the first group was 11.96 days and in the second, 4.76 days. CONCLUSIONS: We still have no clear indications of when to opportunely drain a hepatic abscess.
