Reevaluating the Importance of Daily Step Count for Seniors
Are you constantly looking at your watch or phone to check your step count as you strive to hit 10,000 steps a day? A new study from Mass General Brigham suggests that this goal may not be as crucial as previously thought, especially for seniors. According to the research, taking just 4,000 steps one or two days a week can lead to significant health benefits for older adults.
Older women who participated in the study and took 4,000 steps on just one or two days per week had a 27% lower risk of cardiovascular disease and a 26% lower risk of death compared to those who got less steps. These findings are based on a prospective cohort study of 13,574 older women, with an average age of 72, who wore ActiGraph GT3X+ accelerometers to track their steps over seven days between 2011 and 2015.
Understanding the Study’s Findings
The researchers, led by senior author I-Min Lee, an epidemiologist in the Mass General Brigham Department of Medicine and the Division of Preventive Medicine at Brigham and Women’s Hospital, monitored mortality and cardiovascular disease incidence over the next 10 years. The study revealed that participants who achieved 4,000 steps one or two days per week had a lower risk of mortality and cardiovascular disease compared to those who never reached this threshold.
Moreover, the study found that reaching 4,000 steps three or more days in a week decreased mortality risk further to 40%. The health benefits seem to be associated with the total volume of steps taken, rather than how many days per week a particular threshold was achieved. This suggests that there isn’t a “better” way to get steps, and women with similar total volume of steps, either achieved by consistent steps throughout the week or sporadic steps in just a few days, had similar health benefits.
Implications and Future Research
The study’s findings have significant implications for physical activity guidelines, particularly for older adults. The researchers hope that their study will encourage the addition of step count metrics to physical activity guidelines, including the upcoming 2028 U.S. Physical Activity Guidelines. Lead and corresponding author Rikuta Hamaya notes that promoting taking at least 4,000 steps once per week in older women could reduce mortality and cardiovascular disease risk across the country.
Future research will need to explore whether these effects hold in populations beyond older, American, mostly white women. Additionally, the researchers want to analyze even lower step count thresholds to determine whether less than 4,000 steps can produce similar health benefits.
