0983 Descriptive Characteristics of Sleep Clinic Patients in a Cardiovascular Institute with Predominantly Hispanic Population

Abstract Introduction Sleep is fundamental for cardiometabolic health, and disruptions in sleep patterns have emerged as growing public health concerns. This study examines the demographic characteristics and comorbid burden among sleep clinic patients within a cardiovascular institute in South Florida enriched with Hispanic population. Methods We conducted a retrospective analysis of data from sleep study at Baptist Health South Florida from March 2021 to June 2025. Demographic characteristics, sleep duration, and comorbidities were assessed. Patients were categorized into three groups based on sleep duration: short (< 7 hours), normal (7-9 hours), and long (>9 hours). Chi-square and Kruskal-Wallis tests were used to evaluate the differences in proportions and medians. Results A total of 5983 patients were included in our study. Among them, 55.3% were male, and 46.6% were Hispanic. Median age at presentation was 58 years, and median BMI was 31.4. Moreover, 25% of patients were current or former smokers. Median sleep duration was 7 hours, median sleep latency was 10 minutes, and median sleep irregularity was 0 hours. 2765 (46.2%) patients had stage 1 or above hypertension, and 147 (2.5%) patients had atrial fibrillation (A-Fib). There were 2990 patients in the short sleep duration group, 2808 in the normal duration group, and 185 in the long duration group. There were a greater proportion of men with shorter duration of sleep compared to women (54.3% vs 45.7%). Among Hispanics, 50.89% had short, 46.05% had normal, and 3.05% had long sleep duration. Among non-Hispanics, 49% had short, 47.7% had normal, and 3.1% had long sleep duration. The proportion of patients with A-Fib differed significantly between the three groups (short: 2%, normal: 2.7%, and long: 4.9%, P=0.018). Conclusion In our cohort of cardiovascular patients with substantial Hispanic representation, there were differences in sleep duration based on demographics and comorbid conditions. Future studies should further explore these differences to have a better understanding of sleep disturbances in this cohort. Support (if any)
