Depression among diabetic women in urban centers in Mexico and the United States of America: a comparative study

OBJECTIVE: To compare the prevalence and patterns of depressive symptoms among women with type 2 diabetes in Puebla, Mexico, and Chicago, United States. METHODS: Two cross-sectional studies were conducted independently, in Puebla (September 2010-March 2011) and in Chicago (January-July 2010). Depression symptomatology was evaluated in a random sample of 241 women self-reporting type 2 diabetes in Puebla and a convenience sample of 121 women of Mexican descent seeking care for type 2 diabetes in Chicago. Depressive symptomatology was measured by the Center for Epidemiologic Studies Depression Scale administered in either English or Spanish. Women were similarly socioeconomically disadvantaged with low education levels in both locations. RESULTS: The Chicago sample of women reported higher levels of depression than the Puebla sample (38% versus 17%, P < 0.0001). Among those with comorbid depression and diabetes in both sites, minimal variations in symptoms were observed. Depressive symptoms, specifically the subjective element (feeling sad) and symptoms associated with diabetes (fatigue and sleep problems) were heightened in both groups. More frequent reporting of 'feeling fearful' was statistically significant in Puebla. CONCLUSIONS: Despite a higher prevalence of depression among Mexican immigrant women with diabetes in the United States compared to Mexico, there was little variation in their depressive symptoms, regardless of residence. However, women in Mexico did report a higher incidence of fear. Screening for depression in patients with diabetes should take into account symptoms of fatigue and sleep and the bi-directional relationship of depression and diabetes. //ABSTRACT IN SPANISH: OBJETIVO: Comparar la prevalencia y las características de los síntomas depresivos en mujeres aquejadas de diabetes tipo 2 en Puebla (México) y Chicago (Estados Unidos). MÉTODOS: Se llevaron a cabo independientemente dos estudios transversales, en Puebla (de septiembre del 2010 a marzo del 2011) y en Chicago (de enero a julio del 2010). Se evaluó la sintomatología depresiva en una muestra aleatoria de 241 mujeres con diagnóstico de diabetes de tipo 2 en Puebla, y en una muestra de conveniencia de 121 mujeres de ascendencia mexicana que acudieron en busca de atención de su diabetes de tipo 2 en Chicago. La sintomatología depresiva se midió mediante la Escala de Depresión del Centro de Estudios Epidemiológicos, administrada ya fuera en inglés o en español. En ambas ubicaci
