The fysical activity not just associated with one lower risk of cardiovascular diseaseThere has previously been no threshold for that association, with the lowest risk of cardiovascular disease observed for those who are more active, according to a new study published this week in PLOS Medicine by Terence Dwyer of the University of Oxford in the United Kingdom and his colleagues.
Research has shown that there is one reverse association between self-reported physical activity and the development of cardiovascular disease. However, there is uncertainty about the range of this association, especially at higher levels of physical activity.
In the new study, the researchers used data from 90,211 UK Biobank participants with no previous cardiovascular disease who agreed use an accelerometer to measure your physical activity for a period of 7 days between 2013 and 2015.
Participants in the lower category of physical activity smoked more, had a higher body mass index and C-reactive protein, and were more often diagnosed with hypertension. A total of 3,617 cases of cardiovascular disease were diagnosed in the participants during an average of 5.2 years of follow-up.
People in each increasing quartile of physical activity, for moderate-intensity activity, high-intensity activity, and total physical activity, had less risk of cardiovascular disease.
For example, compared to those in the lowest quartile, those in the second quartile with moderate intensity exercise had a 71% chance of being diagnosed with cardiovascular disease, those in the third quartile were 59% likely, and those in the top quartile had a 46% chance.
Associate professor Aiden Doherty, of the Nuffield Population Health Department, Oxford University, and one of the study’s lead authors, notes that “this is the largest study ever conducted on physical activity and cardiovascular disease excellent measurements with devices. It shows that physical activity is probably even more important in preventing cardiovascular disease than we previously thought. “
“Our findings add weight to the new WHO physical activity guidelines that recommend at least 150 to 300 minutes of moderate to vigorous aerobic activity per week for all adults,” he says.
Professor Terry Dwyer, of the Nuffield Department of Women’s and Reproductive Health at the University of Oxford and lead author of the study, adds that “the results of this study increase confidence that physical activity is likely to be a important way to prevent disease cardiovascular. The estimated potential risk reduction among those who are relatively active is significant and warrants a greater emphasis on measures to increase the level of physical activity in the community. “
Dr. Rema Ramakrishnan, of the Nuffield Department of Reproductive and Women’s Health, Oxford University, and lead author of this study, in turn, notes, “We are confident in the study’s findings because physical activity was assessed objectively with a more valuable tool that can record the frequency, intensity and duration of physical activity rather than self-reporting by the participants. “
