BOAH SCORE: A PRACTICAL TOOL FOR IDENTIFYING CARDIOVASCULAR RISK IN SLEEP DISORDERS

Introdução

The BOAH score (Body Mass Index, Observed Apnea, Age, and Hypertension) is a simplified screening tool that uses objective measures (BMI, age and hypertension) and subjective measures (observation of apnea) to estimate the risk of obstructive sleep apnea (OSA). The association between OSA and cardiovascular diseases, such as angina, is well established in the literature. However, there is a gap regarding the applicability of the BOAH score for predicting the risk of angina in large populations, especially in low-resource settings.

Objetivo

To assess the association between the BOAH score and the presence of angina in NHANES (National Health and Nutrition Examination Survey) participants between 2017 and March 2020.

Métodos

Cross-sectional study with 4,361 participants. The BOAH score was used to categorize the risk of OSA, classifying participants into low or high risk of OSA (score ≥ 2). The score is calculated using the following scoring criteria: BMI (≥ 30 kg/m²-1 point; or ≥ 35 kg/m²-2 points), apneas witnessed during sleep by self-report (1 point), age (≥50 years-1 point) and hypertension (1 point). The presence of angina was identified through a questionnaire, considering chest pain after physical exertion as a diagnostic criterion. Univariate logistic regression analyses, assuming a statistical significance level of 0.05, were carried out using STATA software version 15.1.

Resultados

Logistic regression showed a significant association between high risk of OSA and presence of angina. Participants at high risk of OSA were more than three times as likely to report angina compared to those at low risk (p<0.001; OR: 3.50; 95%CI: 2.26-5.40).

Conclusões

The BOAH score proved to be a relevant indicator for identifying the risk of angina in individuals with suspected OSA, offering a practical and accessible tool for health professionals. In contexts where complex diagnostic methods are not available, the use of the BOAH score can support interventions aimed at improving sleep quality and reducing cardiovascular risk in high-risk populations.
