The Claim

In a clinically based Hispanic/Latino adult cohort, self-reported sleep duration of 6 hours or less per night is associated with a 2.51-fold higher risk of all-cause mortality compared to 6–9 hours of sleep, independent of cardiovascular risk factors and obstructive sleep apnea severity.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

People in this group who say they sleep 6 hours or less each night are more than twice as likely to die from any cause compared to those who sleep 6 to 9 hours—even if they have heart problems or sleep apnea.

  1. Study: The U-Shaped Association between Sleep Duration, All-Cause Mortality and Cardiovascular Risk in a Hispanic/Latino Clinically Based Cohort

    This study found that Hispanic/Latino adults who sleep 6 hours or less per night are about 2.5 times more likely to die from any cause than those who sleep 6–9 hours, even after accounting for heart disease and sleep apnea — just like the claim says.
