Obstructive Sleep Apnea Screening Among Hypertensive Patients in Low-Resource Settings.

INTRODUCTION

In low-resource countries, where sleep medicine centers are limited, screening tools are essential for identifying individuals at risk for obstructive sleep apnea (OSA). This study aimed to identify additional factors that, in combination with the Berlin Questionnaire (BQ) and the Epworth Sleepiness Scale (ESS), could improve the identification of hypertensive patients requiring further evaluation.

SUBJECTS AND

METHODS

This cross-sectional study was conducted at the Family Medicine Service of the Public Health Institution "Dr. Mladen Stojanovic" in Laktasi, Bosnia and Herzegovina, which serves approximately 35,000 inhabitants. Using a questionnaire with defined important parameters alongside screening tools - BQ and ESS - the study aimed to present descriptive indicators of the observed population and to determine identifiers of sleep disorders (primarily OSA) using the chi-square test.

RESULTS

A total of 500 patients with arterial hypertension (254 females and 246 males; median age 60 years (IQR: 50-68 years) and median body mass index (BMI) 26.9 kg/m² (IQR: 24.8-29.8 kg/m²)) were screened using the BQ and the ESS. High risk for sleep disorders was identified in 25.4% of subjects using the BQ and in 25% using the ESS. Smoking, alcohol consumption, a history of causing a traffic accident, and the use of sleeping pills were correlated with positive results on both screening tests.

CONCLUSION

Patients with arterial hypertension who smoke, consume alcohol regularly, have a positive history of causing a traffic accident, and use sleep medications may benefit from screening for OSA and consideration for referral to sleep medicine centers.
