Abstract
Introduction

To establish whether predictors of sleep apnea (OSAHS) from patients with normal body mass index (BMI) could facilitate the prioritization of candidates for sleep tests.

Aim

To describe the role of sex and age as predictors of apnea and hypopnea index (AHI)>5 events per hour in patients with normal BMI (<25kg/m2).

Methods

Retrospective study of patients referred for home respiratory polygraphy level iii.

Results

One hundred and forty-three patients with BMI<25kg/m2, of which 70 had OSA defined by an AHI>5/h were analyzed. The clinical variables to predict AHI>5/h in a multiple logistic regression model, found statistical significance for age>60 years (OR=5.67; 95% CI 2.38–13.53; p<.0001) and male (OR=3.15; 95% CI 1.47–6.73; p<.003).

Conclusion

Forty-eight point ninety-five percent of normal weight patients in a population at risk had OSAHS defined by an AHI>5/h. The sex and age would be risk predictors in this population and most likely in men.

Resumen
Introducción

Conocer predictores de apneas del sueño (SAHOS) en pacientes con índice de masa corporal (IMC) normal podría facilitar la priorización de los candidatos a estudios de sueño.

Objetivo

Describir el papel del sexo y la edad como factores predictores de un índice de apneas e hipopneas (IAH)>5 episodios por hora en pacientes con IMC normal (<25kg/m2).

Métodos

Estudio retrospectivo en pacientes referidos para poligrafía respiratoria domiciliaria y autoadministrada.

Resultados

Se analizaron 143 pacientes con IMC<25kg/m2, de los cuales 70 tuvieron SAHOS definido por un IAH>5/h. Las variables clínicas para predicción de IAH>5/h en un modelo de regresión logística múltiple halló significación para la edad>60 años (OR=5,67; IC 95% 2,38-13,53; p<0,0001) y el sexo masculino (OR=3,15; IC 95% 1,47-6,73; p<0,003.

Conclusión

El 48,95% de los pacientes normopeso en una población de riesgo tuvieron SAHOS definido por un IAH>5/h. El sexo y la edad serían predictores de riesgo en esta población con mayor probabilidad en los varones.
