[Nocturia is not associated with falls among the elderly: a population study in the city of São Paulo]. / La nicturia no se asocia con las caídas del anciano: un estudio de población en la ciudad de São Paulo.

INTRODUCTION: the present study aims to evaluate the association between nocturia and falls in a group of community-living elderly men in the city of São Paulo (Brazil). MATERIAL AND METHODS: under the coordination of the Pan American Health Organization and World Health Organization, a multicenter study named Health, Welfare and Aging (SABE Study) is being conducted to evaluate the living and health conditions of older people in Latin America and Caribbean. In Brazil, this study is evaluating the elderly population (60 years or more) in São Paulo since 2000. The presence of nocturia was taken as the response "yes" to the question "Do you need to void three times or more at night?" .The presence of falls was also taken as the response "yes" to the question "Did you have any fall during the last 12 months?" The intergroup analysis used was the logistic regression. RESULTS: total of 865 men was interviewed, mean age 68 years. It was observed high prevalence of nocturia and falls in all groups, with higher prevalence of both in the eldest group (p<0.001), however, the association of nocturia and falls was not statistically significant in any of the groups (p=0.45). CONCLUSION: this is one of the pioneering studies that assess only the male population, showing that nocturia was not significantly associated with falls. Nocturia and falls are highly prevalent conditions in the elderly, but no association was found between both, so that these variables may be correlated to age and other clinical conditions.

La nicturia no se asocia con las caídas del anciano: un estudio de población en la ciudad de São Paulo / Nocturia is not associated with falls among the elderly: a population study in the city of São Paulo

Introducción: el propósito de este estudio es evaluar la relación entre nictura y caídas en un grupo de hombres ancianos que viven en comunidad en la ciudad de São Paulo (Brasil). Materiales y métodos: bajo la coordinación de la Organización Panamericana de Salud y la Organización Mundial de la Salud, un estudio multicéntrico denominado Salud, Bienestar y Envejecimiento (Estudio SABE) se está llevando a cabo para evaluar las condiciones de vida y salud de los ancianos en América Latina y el Caribe. En Brasil este estudio evalúa la población anciana (60 años o más) en São Paulo desde 2000. La presencia de nicturia se tomó como la respuesta “sí” a la pregunta “¿Necesita orinar tres veces o más por la noche?” La presencia de caídas también se tomó como la respuesta “sí” a la pregunta “¿Ha sufrido una caída en los últimos 12 meses?” Se aplicó la regresión logística para el análisis intergrupal. Resultados: se entrevistó a un total de 865 hombres con una edad media de 68 años. Se identificó una alta prevalencia de nicturia y caídas en todos los grupos, con una mayor prevalencia de ambas en el grupo de los más mayores (p<0,001); sin embargo, la asociación de nicturia y caídas no fue estadísticamente significativa en ninguno de los grupos (p=0,45). Conclusión: éste es uno de los estudios pioneros que solamente evalúa la población masculina, demostrando que la nicturia no está asociada con caídas de manera significativa. La nicturia y las caídas son condiciones altamente prevalentes en los ancianos, pero no se encontró ninguna relación entre ambas, por lo tanto estas variables se podrían correlacionar con la edad y otras condiciones clínicas (AU)
