Abstract

Aims

To compare the effects of asthma and chronic obstructive pulmonary disease (COPD) on the quality of life of patients evaluated using the Saint George Respiratory Questionnaire (SGRQ) through correlating the variables, domains and total score.

Methods

A cross-sectional study from October 2008 to March 2009 with 75 adult outpatients at the University Hospital of Salamanca, Spain. Patients provided their clinical and socio-demographical data after being informed of the study's aims and ethical aspects. The packa ge Statistics SPSS version 17.0 were used for statistical analysis.

Results

65.3% were male and 34.7% female with mean age 60.4 years. 68% had a diagnosis of asthma and 30.7% COPD. Statistically significant differences (p<0.05) between diagnosis and the ‘activity’ domain were found. None were found between gender, smoking, ex-smoking or hypertension and the domains. The income levels were inversely related (p=0.038) with the total score. Statistically significant differences between age and the ‘activity’ (p<0.01) and ‘impact’ (p<0.05) domains and the SGRQ total score were found (p<0.01). The forced expiratory volume in one second (FEV1%pred) only correlated with the ‘activity’ domain (p<0.01) and with the total score (p<0.01).

Conclusions

No variable correlated with all domains and the total score of the instrument. Some presented no statistically significant difference.

Resumo

Objectivos

Comparar os efeitos da asma e da DPOC na qualidade de vida dos doentes avaliados pelo Saint George Respiratory Questionnaire (SGRQ) através de correlações entre as variáveis e os domínios e a pontuação total.

Métodos

Estudo transversal entre Outubro de 2008 a Março de 2009 com 75 adultos das consultas de ambulatório do Hospital Universitário de Salamanca, Espanha. Depois de informar os objectivos do estudo e os aspectos éticos, foi preenchido um formulário com os dados clínicos e socio-demográficos e, em seguida, aplicada a versão espanhola do SGRQ. Para a análise estatística fui utilizada o pacote estatístico Stadistics SPSS versão 17.0.

Resultados

65,3% eram homens e 34,7% mulheres com idade média de 60,4 anos; 68% tinham diagnóstico de asma e 30,7% de DPOC. Foram encontradas diferenças estatisticamente significativas (p<0,05) entre o diagnóstico e o domínio actividade; e nenhuma entre o sexo, o facto de ser fumador, ex-fumador ou hipertenso com os dois domínios. Os níveis socioeconómicos relacionam-se de forma inversa e significativa (p=0,038) com a pontuação total. Foram obtidas diferenças estatisticamente significativas entre a idade e os domínios actividade (p<0,01) e impacto (p<0,05) e a pontuação total do SGRQ (p<0,01). O VEF1VEMS correlacionou-se apenas com o domínio actividade (p<0,01) e com a pontuação total do questionário (p<0,01).

Conclusões

Nenhuma variável se correlacionou com todos os domínios e a pontuação total do instrumento e algumas não apresentaram diferença estatisticamente significativa.
