Abstract

During a median follow-up of 11.8 years, 965 cases of depression and 812 cases of anxiety were recorded among 18,776 participants with cardiovascular disease.

Participants with a healthy sleep pattern had an adjusted hazard ratio of 0.45 for depression compared to those with a poor sleep pattern.
The adjusted hazard ratio for anxiety in individuals with a healthy sleep pattern was 0.77, indicating a potential protective effect.
A linear dose-response relationship was observed, with each one-point increase in healthy sleep score associated with a 18% reduced risk of depression and a 8% reduced risk of anxiety.
These associations were consistent across different types of cardiovascular disease, including coronary heart disease, stroke, heart failure, and atrial fibrillation.

BACKGROUND: Sleep behaviors are potentially modifiable risk factors for common mental disorders and cardiovascular disease (CVD). However, the associations between combined sleep behaviors and common mental disorders among individuals with CVD remain unclear.

METHODS: A total of 18,776 participants with a history of CVD from UK Biobank, who were free of depression or anxiety from 2006 to 2010 were included. A composite healthy sleep score was constructed based on five sleep behaviors (chronotype, sleep duration, insomnia, snoring, and excessive daytime sleepiness). Cox proportional hazard regression models were performed to calculate hazard ratios (HRs) and 95 % confidence intervals (CIs) for incident depression and anxiety.

RESULTS: During a median follow-up of 11.8 years, 965 depression and 812 anxiety cases were recorded. The adjusted HRs for participants with a healthy sleep pattern compared with a poor sleep pattern were 0.45 (95 % CI: 0.35-0.57) for depression and 0.77 (95 % CI: 0.58-1.03) for anxiety. There was a linear dose-response association of healthy sleep score with incident depression and anxiety (HR = 0.82, 95 % CI: 0.77-0.87; HR = 0.92, 95 % CI: 0.86-0.99 per 1-score increase, respectively). Likewise, these associations were observed among individuals with coronary heart disease, stroke, heart failure and atrial fibrillation.

CONCLUSIONS: A healthy sleep pattern is significantly associated with a lower risk of depression among individuals with CVD, highlighting the importance of monitoring and improving sleep health in the prevention of common mental disorders among individuals with CVD.
