Observational Study
Is drinking coffee in the morning better for longevity than drinking it all day?
Original title: Coffee drinking timing and mortality in US adults
Sample Size
40 participants
Study Type
Observational Study
Duration
Median follow-up of 9.8 years (interquartile range: 9.1 years)
Overview
In Plain Language
Drinking coffee in the morning was linked to lower death rates, while drinking coffee throughout the day showed no benefit.

The Numbers
Relative risk (Hazard ratios reported;):
- Morning-type pattern vs non-coffee drinkers: HR 0.84 for all-cause mortality, HR 0.69 for cardiovascular disease mortality
Only relative risk is reported. Without absolute risk numbers, a "22% increase" could mean going from 5% to 6.1% — a small real-world change.
