Influence of social support and stressful life events on adherence to colorectal cancer screening using faecal occult blood test in Spanish medium risk population / Influencia del apoyo social y los acontecimentos vitales estresantes en el cribado de cáncer colorrectal con sangre oculta en heces en población española de riesgo medio

Introduction Colorectal cancer (CRC) is the second cause of cancer-related deaths worldwide. Five-year survival rate in Spain is 57%. The most important prognostic factor is the stage of the tumor at the diagnosis. CRC can be early diagnosed, but the adherence to screening programs is low (<50%). This study aims to ascertain the influence of social support and stressful life events on the adherence to the population screening of CRC with fecal occult blood test in Spanish average risk population. Methods Multicenter case–control study. We conducted a simple random sampling among individuals invited to participate in the colorectal cancer screening program. We analyzed epidemiological and social variables associated with lifestyle and behavioral factors. We performed a descriptive and a bivariant analyses and a logistic regression analysis. Results Four hundred and eight patients (237 cases and 171 controls) were included. Multivariant analyses showed independent association between higher adherence to the screening program and older age (OR: 1.06; 95% CI: 1.01–1.10), stable partner (OR: 1.77, 95% CI: 1.08–2.89) and wide social network (OR: 1.68; 95% CI: 1.07–2.66). Otherwise, lower adherence was associated to perceiving barriers to participate in the program (OR: 0.92; 95% CI: 0.88–0.96). We find a statistically significant association between lower adherence and high impact stressful life events in the bivariant analyses, and the tendency was maintained (OR: 0.63, 95% CI: 0.37–1.08) in the multivariant. Conclusion Social variables decisively influence the adherence to colorectal cancer screening. The implementation of social interventions that improve social support, reduce impact of stressful life events and the design of screening programs that decrease the perceived barriers, will contribute to increase the participation on these programs. Secondary, the colorectal cancer diagnosis will be made in early-stages with the consequent mortality reduction (AU)

El factor pronóstico más importante es el estadio del tumor en el momento del diagnóstico. El CCR se puede diagnosticar precozmente, pero la adherencia a los programas de cribado es baja (< 50%). Este estudio pretende conocer la influencia del apoyo social y los acontecimientos vitales estresantes en la adherencia al cribado poblacional de CCR con sangre oculta en heces en población española de riesgo medio. Métodos Estudio multicéntrico de casos y controles. Realizamos un muestreo aleatorio simple entre los individuos invitados a participar en un programa de cribado de CCR. Analizamos variables epidemiológicas y sociales asociadas al estilo de vida y factores conductuales. Realizamos un análisis descriptivo, un análisis bivariante y una regresión logística. Resultados Se incluyeron 408 pacientes (237 casos y 171 controles). El análisis multivariante demostró una asociación independiente entre una mayor adherencia al programa de cribado y mayor edad (OR: 1,06; IC 95%: 1,01-1,10), tener pareja estable (OR: 1,77, IC 95%: 1,08-2,89) y disponer de una amplia red social (OR: 1,68; IC 95%: 1,07-2,66). Por el contrario, la menor adherencia se asoció a la percepción de barreras para participar en el cribado (OR: 0,92; IC 95%: 0,88-0,96). Encontramos una asociación estadísticamente significativa entre menor adherencia y acontecimientos vitales estresantes de alto impacto en el análisis bivariante. La tendencia se mantuvo (OR: 0,63, IC 95%: 0,37-1,08) en el análisis multivariante (AU)

Perceived barriers and benefits in the participation in faecal occult blood test colorectal cancer screening programme / Barreras y beneficios percibidos en la participación en el cribado de cáncer de colon mediante test de sangre oculta en heces

Background: Colorectal cancer is the second cancer-related cause of death in the world. Tumour stage at diagnosis is the principal prognosis factor of survival. However, the participation in the programme is around 50%. The aim of the study was to identify the benefits and barriers perceived by the population when participating in a colorectal cancer screening programme with faecal occult blood test. Methods: We carried out a cases–controls study with 408 participants. We analyzed epidemiological and social variables associated with lifestyle and behavioural factors based in the Health Belief Model. We conducted a descriptive analysis, and identified variables associated to adherence by a logistic regression. Results: Variables independently associated with the participation in a colorectal cancer screening programme were age (OR 1.06; 95% CI: 1.01–1.11), having a stable partner (OR 1.96; 95% CI: 1.20–3.18), the level of education (OR 1.59; 95% CI: 1.02–2.47) and two of the barriers to participate in the faecal occult blood test screening: “you don’t know how to do one” (OR=0.46; 95% CI: 0.23–0.93) and “it is not that important right now” (OR=0.43; 95% CI: 0.24–0.78). Conclusion: The existing barriers for screening with faecal occult blood test are the best factor predicting. This is relevant when designing the intervention programmes, as they should focus on reducing perceived barriers to increase the participation in colorectal cancer screening, thereby reducing colorectal cancer mortality.(AU)

Antecedentes: El cáncer colorrectal constituye la segunda causa de muerte por cáncer en el mundo. El estadio del tumor al diagnóstico es el principal factor pronóstico de supervivencia. Sin embargo, la participación en el programa está en torno al 50%. El objetivo de este estudio fue identificar los beneficios y las barreras percibidos por la población al participar en un programa de cribado de cáncer de colon mediante el test de sangre oculta en heces. Métodos: Estudio de casos y controles con 408 participantes en el que analizamos variables sociodemográficas, variables asociadas al estilo de vida y factores conductuales basados en el Modelo de Creencias en Salud. Realizamos un análisis descriptivo y, para identificar las variables asociadas a la adhesión al programa de cribado de cáncer colorrectal, una regresión logística. Resultados: Las variables que se asociaron de forma independiente a la participación en el programa fueron la edad (OR 1,06; IC 95% 1,01-1,11), tener pareja estable (OR 1,96; IC 95% 1,20-3,18), el nivel de estudios (OR 1,59; IC 95% 1,02-2,47) y 2 de las barreras para participar en el cribado mediante test de sangre oculta en heces: «no sabe cómo hacerlo» (OR 0,46; IC 95% 0,23-0,93) y «no es un problema importante en el momento actual» (OR 0,3; IC 95% 0,24-0,78). Conclusión: Las barreras existentes para el cribado mediante test de sangre oculta en heces son el mejor factor predictivo de participación. Esto es importante a la hora de diseñar los programas de cribado de cáncer colorrectal, ya que la reducción de las barreras percibidas aumentará la participación en los mismos, reduciendo así la mortalidad por cáncer de colon.(AU)

Validación al castellano del cuestionario Rawl de cribado de cáncer colorrectal con sangre oculta en heces / Rawl's questionnaire spanish validation for colorectal cancer screening with faecal occult blood testing

Introducción: La supervivencia del cáncer colorrectal es del 57% a los 5 años, en parte debido a un diagnóstico tardío por una baja participación en los programas de cribado. Son necesarios instrumentos que analicen las causas de participación.Objetivo: Comprobar la validez y consistencia interna de la versión en castellano del cuestionario de Rawl para el cribado de cáncer colorrectal con sangre oculta en heces.Tipo de estudio: Metodología de validación de cuestionarios.Localización: Tres centros de salud de Valencia.Variables: Edad, sexo, estado civil, nivel de estudios, clase social, consumo de tabaco, alcohol, índice de masa corporal, antecedentes personales y familiares de cáncer.Resultados: Se estudiaron 408 individuos (237 casos y 171 controles). La edad media fue de 59,45 (DE 5,17) años. La consistencia interna de todas las variables alcanzó una alfa de Cronbach de 0,796. El alfa de Cronbach de la dimensión beneficios del cribado fue de de 0,871 y para la dimensión barreras al cribado fue de 0,817. Los coeficientes de correlación intraclase del test-retest para la dimensión de los beneficios del cribado fue de 0,809 (IC 95% 0,606-0,913) y de 0,499 (IC 95% 0,126-0,750) para las barreras.Conclusión: La versión en castellano del cuestionario Rawl es válido, fiable y reproducible. Con lo que disponemos de un elemento validado en España con el que objetivar barreras y beneficios percibidos en un programa de cribado poblacional.
