Consistencia interna y estructura internadel cuestionario AUDIT en amerindios / Internal consistency and dimensionality of the AUDIT among Amerindians

Objetivo: determinar la consistencia interna y la dimensionalidad del AUDIT en una muestra de amerindios residentes en Bogotá, Colombia. Metodología: se diseñó un estudio metodológico. Participaron 184 amerindios, 99 hombres y 85 mujeres. La media para la edad fue 32,0 años (DE=14,0) y para laescolaridad, 6,1 años (DE=3,7). Se estimaron las correlaciones corregidas de cada ítem con la puntuación total, la consistencia interna (alfa de Cronbach y omega de McDonald) y la dimensionalidad (estructura interna).Resultados: las correlaciones corregidas entre los ítems y la puntuación total seencontraron entre 0,368 y 0,788. El AUDIT mostró alfa de Cronbach de 0,879; omega de McDonald de 0,886; y un factor que explicó el 50,6% de la varianza. Conclusiones: el AUDIT muestra excelente consistencia interna y una estructura unidimensional en amerindios residentes en Bogotá, Colombia.

Prevalence of Alcohol Problem Drinking Among the Indigenous Population in Colombia / Prevalencia del consumo problemático de alcohol entre los indígenas colombianos

Abstract Background: Some studies have reported a high prevalence of alcohol drinking problem among indigenous populations in Latin America. However, there is no available information on some of the variables associated with alcohol problem drinking. Objective: To determine the prevalence and some factors associated with alcohol problem drinking among a sample of Colombian indigenous population in Bogotá, Colombia. Method: A cross-sectional study was conducted using a Colombian indigenous population sample over 15 years old living in the community. Alcohol problem drinking was quantified with the Alcohol Use Disorders Identification Test (AUDIT) (Cut-off point of 8). Non conditional logistic regression was computed to adjust associated variables. Results: A total of 184 subjects from the indigenous population participated in this research. The mean age was 32.0±14.0 years and educated for 6.0±3.7 years. A total of 84 participants (45.7%) reported alcohol problem drinking. The AUDIT showed Cronbach alpha of 0.877. Male sex (OR=4.2; 95%CI, 2.2-7.6), and longer time living in Bogota (OR=1.8; 95%CI, 1.0-3.2) were associated with alcohol problem drinking. Conclusions: Almost 50% of the Colombian indigenous population living in Bogota meet criteria for alcohol problem drinking. Male gender and longer time living in Bogota are related to alcohol problem drinking. Further studies are needed to formally identify alcohol abuse or dependence.

Resumen Antecedentes: Algunos investigadores informan de alta prevalencia de consumo problemático de alcohol entre los indígenas de América Latina. Sin embargo, no hay información disponible acerca de algunas variables asociadas al consumo problemático de alcohol. Objetivo: Estudiar la prevalencia y algunos factores asociados al consumo problemático de alcohol en una muestra de una comunidad indígena en Bogotá, Colombia. Método: Se llevó a cabo un estudio transversal. Participó una muestra de indígenas mayores de 15 años. El consumo problemático de alcohol se cuantificó con el test de identificación de trastornos del alcohol (AUDIT) (punto de corte, 8). Se realizó un modelo de regresión logística no condicional para ajustar las variables asociadas. Resultados: Un total de 184 indígenas participaron en este estudio. La media de edad fue de 32,0 ± 14,0 años y el tiempo de escolarización, 6,0 ± 3,7 años. Un total de 84 participantes (45,7%) informaron de consumo problemático de alcohol. El AUDIT mostró una consistencia interna de 0,877. El sexo masculino (odds ratio = 4,2; intervalo de confianza del 95%, 2,2-7,6) y mayor permanencia en Bogotá (odds ratio = 1,1; intervalo de confianza del 95%, 1,0-3,2) se asociaron al consumo problemático de alcohol. Conclusiones: En Bogotá, cerca del 50% de los indígenas colombianos hacen un consumo de alcohol problemático. El sexo masculino y vivir en Bogotá están relacionados con el consumo problemático de alcohol. Se necesitan más investigaciones en que se realicen diagnósticos formales de abuso o dependencia de alcohol.
