Key result
The combination of short sleep duration (<7 hours) and high obstructive sleep apnea risk was associated with a 72% lower odds of having better cardiovascular health in hemodialysis patients (OR 0.28).
Why the study?
The separated and combined associations of OSA risk and sleep duration with ideal cardiovascular health metrics in hemodialysis patients remained to be explored.

In hemodialysis patients, short sleep duration and high risk of obstructive sleep apnea are independently and synergistically associated with poorer ideal cardiovascular health metrics.
Background: The purpose of this study was to explore the separated and combined associations of OSA risk and sleep duration with ideal cardiovascular health metrics in HD patients. Methods: 470 HD participants (average: 59.48±12.89 y, 281 men) were included in this study. Sleep duration was measured as self-reported average sleep time during the previous month. OSA risk was evaluated by using STOP-BANG questionnaire. Participants were divided the into three groups by the number of ideal CVH metrics: 0-2,3-4, and 5-7. Ordinal logistic regression was performed to model the associations of CVH metrics with sleep duration, OSA risk, and their combined effects by adjusting for certain covariates. Results: After adjusting for covariates, short sleep duration (< 7h) (OR=0.53; 95% CI [ 0.30, 0.92]) and OSA risk (OR=0.58; 95% CI [0.32, 0.83]) were negative associated with better CVH (ideal vs. intermediate; intermediate vs. poor), respectively. For HD patients with both short sleep duration and OSA risk, the proportional odds of having better CVH were 72% lower (odds ratio 0.28 [95% CI 0.13, 0.60]). Conclusions: Short sleep duration and OSA risk are separated and combined related to poor CVH in hemodialysis patients. Suitable interventions for sleep may minimize the risk of subsequent cardiovascular disease.

Zhang et al. (2023) conducted a cross-sectional in Hemodialysis (n=470). Short sleep duration (<7h) and high OSA risk vs. 7-9h sleep duration and low OSA risk was evaluated on Better cardiovascular health (ideal vs. intermediate; intermediate vs. poor) based on AHA 7 ideal CVH metrics (OR 0.28, 95% CI 0.13-0.60, p=0.001). The combination of short sleep duration (<7 hours) and high obstructive sleep apnea risk was associated with a 72% lower odds of having better cardiovascular health in hemodialysis patients (OR 0.28).
