RESUMO

A disfunção eréctil (DE) é uma situação de elevada prevalência nas sociedades moderna, em parte devido ao envelhecimento da população. A função eréctil (FE) é um componente importante do funcionamento sexual mas com uma relação moderada com a DE. O objectivo deste estudo é avaliar a relação entre DE, FE e qualidade de vida (QDV). Participaram 133 homens Portugueses saudáveis, com idades entre 21 e 78 anos (M=43,86; DP= 14,39), que responderam a um questionário de auto resposta segundo uma metodologia mail type. A DE foi definida segundo os critérios do IEEF-5, uma versão reduzida do IIEF (International Index of Erectile Function). A QDV foi avaliada com recurso ao SF-36. Os resultados mostram que o grupo DE (32,8% da amostra) manifesta valores de QDV mais baixos dos que o grupo não DE principalmente nas dimensões do componente físico. A FE enquanto resultado proveniente de todos os domínios do IIEF aumenta (principalmente nos domínios do Componente Físico). Os dois componentes do SF-36 (físico e mental) mostram tendência para aumentar quando a FE aumenta. Em conclusão encontrámos uma associação clara e positiva entre a percepção de FE e a QDV com preponderância para as dimensões do componente físico desta mas com uma clara interacção com o Componente Mental.

ABSTRACT

Erectile Dysfunction (ED) it’s a prevalent dysfunction in modern societies partly because these societies are growing old. Erectile Function (EF) is an important component of sexual functioning but with moderate relation with ED. The purpose of this work is to assess the quality of life (QOL) factors associated with ED and EF. 133 Portuguese healthy males, aged between 21 and 78 years of age (M=43,86; SD=14,39), answer to a self-rated questionnaire mail typed. ED was defined using the Reduced International Index of Erectile Function (IIEF-5) and the FE using the general form of IIEF. QOL was measured through the SF-36 questionnaire. Results shows that the ED group (32,8% of the sample) exhibits statistically significant lower results in physical domains of QOL in comparison with the non-Ed group. The EF as a result of all the domain of IIEF increases as the scores of the scales of the SF-36 increase (mainly the physical domains). The two SF-36 summary components (physical and mental) showed an upward trend. In conclusion, we found a clear pattern of positive association between self-perceived EF and QOL, and significant differences between the ED group and the non-Ed group favouring the non-Ed group for the same variables. This association was stronger for the physical summary component than for the mental one, but with a consistent interaction with the mental component.

Key words: Erectile dysfunction, erectile function, quality of life.
