Abstract
Objective

To study the relationship between disability and health-related quality of life in women with vertigo of peripheral origin.

Methods

Cross-sectional study in 26 women diagnosed with vertigo, classified by type of peripheral vestibular disturbance: benign paroxysmal positional vertigo (BPPV), vestibular neuritis, Ménière's disease, post-trauma and others. In a self-report interview, a 12-item shortform (SF-12) health survey on quality of life was applied; disability was assessed with the questionnaire “Dizziness Handicap Inventory” (DHI). Measures of central tendency, dispersion for the domains and types of vestibular disturbance were used and internal DHI consistency and inter-scale correlation were calculated.

Results

Patients in the vestibular neuritis and Ménière groups displayed a higher level of disability according to the DHI functional (29.5±5.5 vs 27.0±8.8) and physical domains (23.0±4.1 vs 21.5±6.6). Based on the SF-12 domains, greater deterioration in quality of life was perceived in physical (22.9±3.9 vs 22.6±4.6) and emotional performance (15.4±5.0 vs 11.3±6.0), respectively. Acceptable and significant inverse correlations were found between the physical component summary (PCS-12) of the SF-12 and the physical, emotional and functional aspects of the DHI questionnaire (r=−0.51 to −0.78, P<.01). Internal consistency (Cronbach's alpha index) of the DHI questionnaire was appropriate for the sample.

Conclusions

The DHI and the SF-12 are useful, practical and valid instruments for assessing the impact of dizziness on the quality of life of patients with this symptom.

Resumen
Objetivo

Estudiar la relación entre la discapacidad y la calidad de vida en mujeres con vértigo de origen periférico.

Métodos

Estudio transversal, en 26 mujeres con diagnóstico clínico de vértigo clasificado según el tipo de alteración vestibular periférica: vértigo posicional paroxístico benigno (VPPB), neuronitis vestibular, enfermedad de Ménière, postrauma y otros. Se aplicó por entrevista autodiligenciada el cuestionario de calidad de vida 12-item short (SF-12) y la discapacidad se evaluó con el cuestionario «Dizziness Handicap Inventory» (DHI). Se usaron medidas de tendencia central, dispersión para los dominios y tipo de alteración vestibular; cálculo de consistencia interna para el DHI y correlación interescalas.

Resultados

Los pacientes del grupo neuronitis vestibular y enfermedad de Ménière acusaron mayor nivel de discapacidad según el DHI en los dominios aspecto funcional (29,5±5,5 vs. 27,0±8,8) y físico (23,0±4,1 vs. 21,5±6,6) y una percepción de mayor deterioro en su calidad de vida según el SF-12 en los dominios desempeño físico (22,9±3,9 vs. 22,6±4,6) y desempeño emocional (15,4±5,0 vs. 11,3±6,0) respectivamente. Correlaciones inversas aceptables y significativas se encontraron entre el constructo físico (PCS-12) del SF-12 y los aspectos físico, funcional y emocional del cuestionario DHI (r=−0,51 a –078, p<0,01). La consistencia interna (índice a de Cronbach) del cuestionario DHI fue adecuada para la muestra.

Conclusiones

El DHI y el SF-12 son herramientas útiles, prácticas y válidas para evaluar el impacto del vértigo en la calidad de vida de los pacientes con este síntoma.
