The American Heart Association (AHA) awarded the Paul Dudley White International Scholar Award to an abstract co-authored by Dr. Michael LaMonte, research associate professor at the University of Buffalo School of Public Health and Health Professions. Th award recognizes the highest-ranked abstract in the U.S. submitted to the AHA Epidemiology and Prevention Council/Lifestyle and Cardiometabolic Health Council.
The winning abstract is from the Women’s Health Initiative (WHI) Objective Physical Activity and Cardiovascular Health (OPACH) study, reporting on accelerometer steps per day and incidence of cardiovascular disease (CVD) events in older women. Lead author is Dr. Andrea LaCroix, professor and chair of the Department of Epidemiology at University of California San Diego; Dr. LaMonte is senior author.
“We used accelerometer measures in OPACH to estimate step counts (as opposed to acceleration forces), which has been called for by AHA and other health organizations to help simplify physical activity recommendations,” Dr. LaMonte says. “Our findings showed statistically significantly lower risk of having a major cardiovascular event (i.e., heart attack, stroke) or dying from cardiovascular causes beginning at around 2,500 steps per day, far less than the 10,000 steps per day that has become popularized but for which scientific evidence was limited, particularly in older adults who are likely unable to achieve such high daily step counts.” Dr. LaMonte also indicated that these results, while being interesting, need confirmation in other studies that include men and younger adults, but do appear promising.
Drs. LaCroix, LaMonte and their colleagues presented data from the study at the EPI | Lifestyle 2020 Scientific Sessions Conference.
