[Prevalence of respiratory disorders during sleep and associated factors]. / Prevalencia de los trastornos respiratorios del sueño y factores asociados.

OBJECTIVE: To calculate the prevalence of respiratory disorders during sleep (RDS), apnoea, and related factors, in a rural population. DESIGN: Prevalence study. PARTICIPANTS: Random sample of 228 individuals chosen from a health centre's appointment records. MAIN MEASUREMENTS: Anamnesis about sleep and respiratory disorders during sleep, anthropometric measurements, Epworth Sleepiness Scale, nocturnal pulse oximetry, and polysomnography. RESULTS: Five subjects were found to have RDS plus sleepiness. The estimated prevalence of apnoea was 2.1% (95% CI, 0.3-3.9). The prevalence of RDS, daytime sleepiness and habitual snoring was 25.4% (20.2-30.5), 7.4% (3.9-10.8), and 30.7% (25.4-36.4), respectively. RDS was associated with age, body mass index (BMI), and snoring. CONCLUSIONS: RDS is a common problem in our population. In this study, age, BMI and snoring were found to be factors associated with RDS.

Objetivo. Estimar la prevalencia de los trastornos respiratorios (TRS) y el síndrome de apnea durante el sueño (SAS), así como de los factores asociados, en una población rural. Diseño. Estudio de prevalencia. Participantes. Muestra aleatoria de 228 individuos elegidos del fichero de cita previa de un centro de salud. Mediciones principales. Anamnesis dirigida al sueño y trastornos respiratorios durante éste, medidas antropométricas, escala de hipersomnolencia de Epworth, pulsioximetría nocturna y polisomnografía. Resultados. Hemos encontrado 5 personas con TRS e hipersomnolencia. La prevalencia de SAS es del 2,1% (intervalo de confianza [IC] del 95%, 0,3-3,9). La prevalencia de TRS, hipersomnolencia diurna y ronquido habitual es del 25,4% (IC del 95%, 20,2-30,5), el 7,4% (IC del 95%, 3,9-10,8) y el 30,7% (IC del 95%, 25,0-36,4), respectivamente. La edad, el índice de masa corporal (IMC) y la presencia de ronquido son factores asociados a los TRS. Conclusiones. Los TRS son una entidad frecuente en nuestra población. En este estudio, la edad, el IMC y el ronquido son factores asociados con las alteraciones respiratorias del sueño
