Race, Sleep, and Oxygen: Unveiling Desaturation Disparities in Sleep Apnea

Frequent drops in oxygen saturation during sleep, a key characteristic of sleep apnea, are used for diagnosis and severity assessment. However, recent data has raised concerns about the accuracy of oxygen saturation measurements in individuals with dark skin. In a pioneering study presented at the Annual Sleep Medicine Conference, researchers examined the extent to which episodic desaturations during sleep vary among racial and ethnic groups, taking into account ventilatory deficit and other factors. These findings highlight the importance of addressing race-specific considerations in sleep apnea management and the role of Neurobit's innovative solutions in improving sleep health outcomes.

Sleep apnea affects a significant portion of the population and is associated with various health complications. Accurate measurement of oxygen desaturation levels during sleep is crucial for diagnosing and managing the condition. However, recent observations during the COVID-19 pandemic have raised concerns about the accuracy of oximeters in individuals with dark skin. This study aimed to explore the racial and ethnic differences in the severity of desaturations during sleep, accounting for ventilatory deficit and other potential confounders. These findings have important implications for personalized sleep apnea management, emphasizing the need for tailored solutions.

The researchers conducted a comprehensive analysis using data from the Multi-Ethnic Study of Atherosclerosis (MESA) Exam 5. The sample included participants who underwent unattended polysomnography with a finger pulse oximeter. Severity of desaturation was quantified using "hypoxic burden," calculated as the total area under respiratory event-related desaturation curves. The ventilatory deficit, defined as the event-specific area under the ventilation signal, was also considered. Multiple linear regression models were utilized to evaluate race/ethnicity-specific differences in desaturation sensitivity after adjusting for various factors, including age, sex, BMI, smoking, and supine sleep position.

The results revealed noteworthy differences in desaturation sensitivity among racial and ethnic groups after accounting for confounding factors. Black participants demonstrated lower desaturation sensitivity than White participants, even after adjusting for age, sex, BMI, smoking, and sleep position. These findings highlight the need to consider race-specific factors in sleep apnea management and raise questions about the underlying physiological and device-related factors contributing to differences in measured oxygen saturation during sleep across different ethnic backgrounds.
