Abstract
OBJECTIVE: This study aims to investigate the incidence of positional obstructive sleep apnea-hypopnea syndrome (P-OSAHS) and patient profile in OSAHS patient population.
METHODS: Files of 161 patients (134 males, 27 females; mean age 49 years; range, 32 to 65 years) who underwent polysomnography (PSG) test between January 2016 and December 2017 in a sleep laboratory were retrospectively screened. Gender, age, height, weight, Body Mass Index (BMI), neck circumference measurements and PSG test data were recorded. Patients were divided into two groups as P-OSAHS and non-positional OSAHS (NonP-OSAHS).
RESULTS: Patients with P-OSAHS accounted for 41.6% of all patients diagnosed with OSAHS. The female gender ratio of P-OSAHS group was statistically significantly lower than NonP-OSAHS group (6% vs. 24.5%; p=0.002). Mean BMI of P-OSAHS group was statistically significantly lower than NonP-OSAHS group (p=0.002). No statistically significant difference was detected in the neck circumference averages between the groups (p=0.708). Mean apnea-hypopnea index (AHI) was statistically significantly lower in the P-OSAHS group (p<0.001).
CONCLUSION: Of the OSAHS patients, 41.6% were P-OSAHS patients. The BMI and AHI values of P-OSAHS patients were lower than NonP-OSAHS patients.
