Short sleep and physical inactivity are independently and jointly associated with prevalent cardiovascular disease in US adults
In a cross-sectional study of 1,577,591 US adults, short sleep (OR 1.26, 95% CI 1.22-1.30) and long sleep (OR 1.17, 95% CI 1.13-1.21) were independently associated with prevalent cardiovascular disease, as was physical inactivity (OR 1.11, 95% CI 1.09-1.14). The joint effect of short sleep and inactivity conferred the highest risk (OR 1.38, 95% CI 1.31-1.44), with no significant additive interaction (RERI -0.03, 95% CI -0.11 to 0.06), suggesting independent, additive risks.

Short sleep and physical inactivity are independently and jointly associated with prevalent cardiovascular disease in US adults The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 34/100 (low).
The Claim
Short sleep and physical inactivity are independently and jointly associated with prevalent cardiovascular disease in US adults
This conclusion is most relevant to: US adults (n=1,577,591) from the Behavioral Risk Factor Surveillance System (2014-2022).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Independent and joint associations of sleep duration and physical activity with cardiovascular disease: a cross-sectional study of 1.6 million US adults. (Frontiers in public health, 2026) —
How It Works
The proposed biological pathway:
- ▸Short sleep and physical inactivity are independently associated with cardiovascular disease risk
- ▸The joint effect of short sleep and inactivity is higher than either alone
- ▸No significant additive interaction (RERI -0.03) indicates no synergy beyond additive effects
- ▸Result: Both factors contribute independently to cardiovascular risk, supporting combined lifestyle interventions
Who Might Benefit
Evidence fit by population:
- ▸US adults (n=1,577,591) from the Behavioral Risk Factor Surveillance System (2014-2022)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Cross-sectional design cannot establish causality
- ▸Self-reported sleep duration and physical activity may introduce measurement bias
- ▸Residual confounding from unmeasured variables (e.g., diet, stress) despite rigorous adjustment
Frequently Asked Questions
What is the risk of cardiovascular disease for people with short sleep and physical inactivity?▼
The joint effect of short sleep and physical inactivity was associated with a 38% higher odds of prevalent cardiovascular disease (OR 1.38, 95% CI 1.31-1.44) compared to those with normal sleep and adequate activity.
Is there a synergistic interaction between sleep duration and physical activity?▼
No, the relative excess risk due to interaction (RERI) was -0.03 (95% CI -0.11 to 0.06), indicating that the risks are additive and independent, not synergistic.
What were the independent effects of short sleep and long sleep?▼
Short sleep was associated with a 26% higher odds (OR 1.26) and long sleep with a 17% higher odds (OR 1.17) of prevalent cardiovascular disease, compared to normal sleep.
What is the recommended public health approach based on this study?▼
The study suggests integrating sleep hygiene and physical activity into holistic '24-h movement' prescriptions to reduce cardiovascular disease risk.
