Abstract

PURPOSE: Recent studies have shown strong association between insulin resistance, diabetes mellitus and sleep apnea. Ethnic variance in the prevalence of diabetes in patients with OSA has not been well described. The objective of this study was to describe the prevalence of diabetes mellitus in a cohort of Hispanic and Caucasian patients with OSA.

METHODS: A retrospective chart review of 103 Hispanic patient, and 70 Caucasian patients with OSA was carried out. All patients had undergone full night baseline polysomnography. We excluded charts of patient who underwent split night studies and those who did not have REM sleep.

RESULTS: Both groups were well-matched in terms of age, gender distribution and BMI. Prevalence of self-reported diabetes mellitus in Hispanic patient with OSA was 42%, as compared to Caucasian with 24% (p value = 0.005). A REM AHI of greater than 20 was significantly associated with increase prevalence of diabetes in Hispanic population; this association was not seen in the Caucasian population (Table 1).

CONCLUSION: There is a very high prevalence of diabetes mellitus in an unselected cohort of Hispanic patients with OSA, as compared to Caucasians. A high REM AHI seems to be a strong predictor of the presence of diabetes mellitus, in Hispanics but not in Caucasians.

CLINICAL IMPLICATIONS: Hispanic patients with sleep apnea should be screened for glycemic intolerance, especially when high REM AHI is noted.
