A recent study of United States adults offers insights into how the daily habits of extended sitting and coffee consumption might jointly impact mortality rates.
Published in the Springer Nature title BMC Public Health in April, the study was led by a team at the Medical College of Soochow University in Suzhou, China. It drew upon health data on more than 10,000 U.S. adults through the publicly available National Health and Nutrition Examination Survey (NHANES).
The study found that, over a 13-year period, prolonged sitting, defined as more than eight hours a day, was linked to a significantly higher risk of death from all causes, and specifically from cardiovascular disease (CVD).
Adults who routinely sat for extended periods experienced a 46% higher risk of all-cause mortality, and a 79% higher risk of CVD mortality, compared to those who sat for less than four hours daily.
However, the research team found that regular coffee consumption might offer a protective effect. Study participants in the highest quarter of coffee intake were 33% less likely to die of any cause, and 54% less likely to dive of CVD, than non coffee drinkers.
A joint analysis within the study additionally found that non coffee drinkers who sat more than six hours per day were 58% more likely to die of any cause than coffee drinkers who sat for less than six hours.
“This study identified that sedentary behavior for more than [six hours per day] accompanied with non-coffee consumption, were strongly associated with the increased risk of mortality from all-cause and CVD,” the study states.
The research team noted a limitation that tends to pop up on nearly all health-related studies involving coffee: consumption was self-reported and did not distinguish between different coffee drink types or ingredients.
Wrote the researchers, “Given that coffee is a complex compound, further research is needed to explore this miracle compound.”
