“…With this in mind, it is important to compare HRQOL among different populations using disease-specific instruments that focus on the factors most relevant to the disease, are more sensitive to the impact of the symptoms on the QOL, which can be underestimated by generic instruments, and are more appropriate for treatment trials [1,7]. In fact, in a previous study based on IBS patients from tertiary referral centers, it was found that Mexican patients reported longer flare-ups and more physician visits during the previous year compared to patients from Los Angeles but there were no differences in HRQOL assessed by a generic instrument, the SF-36 [23].…”

The Irritable Bowel Syndrome (IBS)-Quality of Life (QOL) is the most extensively validated health-related quality of life (HRQOL)-specific instrument for IBS with appropriate evidence for psychometric validity. Our aim was to linguistically validate the IBS-QOL for Mexico according to standard guidelines, to conduct further psychometric validation, and to compare the HRQOL between IBS patients from Mexico and North Carolina (University of North Carolina). Construct validity was tested by correlating scores from the Mexican Spanish IBS-QOL with those for anxiety and depression obtained by the Hospital Anxiety and Depression scale. Also, HRQOL from Rome I female IBS patients who consulted a tertiary referral center in Mexico was compared with that of female patients from UNC matched by age and bowel habit. A general univariate linear model was done to determine the most important variable over HRQOL, place of origin, or bowel habit. The majority of the IBS-QOL items had a negative correlation with depression as well as with anxiety. Compared to patients from UNC, the Mexican ones reported significant lower scores on Body Image and Health Worry and a trend in Interference with activities and in the Overall score. There were some differences in Dysphoria and Interference that were related to bowel habit, independently of the place of origin. In conclusion, the IBS-QOL validated in Mexican Spanish has shown construct validity. Using this instrumentwe found that female IBS patients who consulted a tertiary referral center in Mexico have lower HRQOL than those in North Carolina at least in factors such as Body Image and Health Worry.

“…En Latinoamérica, en estudios basados en la comunidad, la prevalencia de SII en Brasil, Colombia, México y Uruguay osciló entre el 9 y el 18% [18][19][20][21][22][23] . La edad de presentación de los pacientes con SII tiene un amplio rango, de 16 a 89 años, con un promedio de 42 años 19,[23][24][25][26] . La distribución por sexos del SII en la comunidad es de 2 a 4 mujeres por cada varón 20,[23][24][25] , y afecta aproximadamente a un 15% de las mujeres y a un 5% de los varones.…”

“…La edad de presentación de los pacientes con SII tiene un amplio rango, de 16 a 89 años, con un promedio de 42 años 19,[23][24][25][26] . La distribución por sexos del SII en la comunidad es de 2 a 4 mujeres por cada varón 20,[23][24][25] , y afecta aproximadamente a un 15% de las mujeres y a un 5% de los varones. Según las encuestas, sólo entre el 10 y el 50% de las personas que presentan SII consultan al médico; son los denominados «pacientes», en contraposición a los «no pacientes», que son los individuos que cumplen con los criterios diagnósticos del SII, pero que no buscan atención médica.…”

“…Hasta el 31% de los pacientes con SII consulta al gastroenterólogo y este trastorno es el motivo de consulta más frecuente a este especialista [22][23][24] . Cada paciente demanda un promedio de 3 a 3,6 consultas al año, en comparación con una consulta anual en los pacientes con otros diagnósticos 21,25 . Los pacientes que consultan con mayor frecuencia se ubican en el grupo de edad de 31 a 50 años, de forma similar a lo comunicado en la bibliografía mundial, lo que probablemente guarda relación con el hecho de que éstos presentan síntomas más graves 27 .…”

“…A pesar de que el diagnóstico se realiza sobre la base de criterios aceptados, se utiliza un alto número de estudios de laboratorio paraclínicos 28 . En México, a los pacientes con SII se les efectúan en promedio 5 estudios de laboratorio y de gabinete antes de llegar al diagnóstico de SII, y se realiza un promedio de 6 estudios anuales posteriormente 25 . Además, los pacientes con SII tienen 22 veces más riesgo de apendicectomía y 2 veces más de colecistectomía 26 .…”
