Sedentary lifestyles are one of the most common lifestyles in today's society and a risk factor for many health conditions. The World Health Organization has long listed sitting as one of the top 10 causes of death, and the harm of sitting is second only to smoking. Early studies have shown that sitting for long periods of time increases the risk of heart disease, diabetes, depression, and more.
Coffee, the life-sustaining artifact of contemporary people, is the most popular beverage in the world. Because it contains a lot of caffeine, it is often drunk by people to awaken their minds and improve work efficiency. Several studies in the past have shown that drinking coffee regularly can provide multiple health benefits.
However, the link between sedentary time and coffee intake and mortality is unclear.

The study showed that drinking coffee every day may reduce the risk of death from sedentary lifestyles. People who sat for more than 8 hours a day had a 46% increased risk of death and a 79% increased risk of cardiovascular death compared to those who were sedentary for less than 4 hours a day. Those with the highest coffee intake had a 33% lower risk of death and a 54% lower risk of cardiovascular death compared to non-coffee drinkers.
The combined sedentary and coffee analysis found that people who sat for more than six hours and did not drink coffee had a 58% increased risk of death compared to those who were sedentary for less than six hours a day and drank coffee. The association between prolonged sedentary and increased mortality was only observed in non-coffee drinkers, but not in coffee drinkers.
In the study, researchers analyzed 10,639 participants in the National Health and Nutrition Examination Cohort (NHANES), collected participants' coffee intake through a dietary questionnaire, participants self-reported daily sedentary time, and analyzed the association between sedentary time and coffee intake and all-cause mortality and cardiovascular disease mortality.
Sedentary time is divided into: 0-4 hours, 4-6 hours, 6-8 hours, and more than 8 hours, and coffee intake includes: no drinking, 0.23-326 g/day, 326-540 g/day.
Of all participants, 48% were sedentary for more than 6 hours a day, and 23% were sedentary for more than 6 hours a day without coffee.
During a follow-up period of up to 13 years, a total of 945 deaths were recorded, of which 284 died from cardiovascular disease.
The study found that people who sat for more than 8 hours a day had a 46% increased risk of death and a 79% increased risk of cardiovascular death compared to those who were sedentary for less than 4 hours a day. Those with the highest coffee intake had a 33% lower risk of death and a 54% lower risk of cardiovascular death compared to non-coffee drinkers.
The independent relationship between sedentary, coffee and death
The combined sedentary and coffee analysis found that people who sat for more than six hours and did not drink coffee had a 58% increased risk of death compared to those who were sedentary for less than six hours a day and drank coffee.
The risk of death from cardiovascular disease is similar, with people who sit for more than six hours and do not drink coffee for more than six hours a day have a 110% increased risk of death from cardiovascular disease compared to those who sit for less than six hours a day and drink coffee.
It is important to note that the association between prolonged sitting and increased mortality was only observed in non-coffee drinkers, but not in coffee drinkers. For non-coffee drinkers, sedentary time was associated with increased all-cause mortality, while for those with the highest coffee intake, sedentary time was not associated with all-cause mortality.
In addition, the researchers analyzed different age groups, and the risk of all-cause mortality was much higher for people over 65 who were sedentary for more than eight hours, with a 69 percent increase.
In summary, the results suggest that coffee drinking may reduce the harm of sedentary life, and sedentary behavior is independently associated with higher all-cause mortality and cardiovascular mortality, compared with coffee is independently associated with lower all-cause mortality and cardiovascular mortality. The joint analysis showed that the association between prolonged sedentary and increased mortality was only found in non-coffee drinkers. (Source: Yinuovi)
