Researchers at Columbia University and the University of Rhode Island detailed the relationship between obesity and physical activity among older adults. About 71% of adults age 60 and older are classified as overweight or obese. The National Center for Health Statistics estimates that by the year 2030, 20% of the U.S. population will be 65 and older. Because of this, public health experts are advocating that older adults become more physically active.
One of the most persistent problems related to obesity among older adults is the risk of functional limitations or disability. High levels of body fat are associated with greater functional limitations and disability, a relationship that becomes more problematic with age. Contrasting this with findings that physical activity is associated with a delay or decrease in the prevalence of chronic health problems, decreased levels of anxiety and depression, decreased morbidity and mortality, and reduced risk of falling in older adults, public health experts believe that physical activity and exercise for all will benefit their health and reduce the functional limitations they would otherwise face if they live a sedentary lifestyle as they age.
More than 800 participants took part in the Study of Exercise and Nutrition in Older Rhode Islanders (SENIOR), a community-based health promotion study designed to improve nutrition and increase physical activity among community-dwelling older adults. The researchers confirm previous studies that demonstrate that obesity and physical activity have an independent impact on health. Yet, despite this independence, physical activity and obesity are related in that obese older adults tend to be more prone to physical disability. The only way to counteract the negative impact that obesity has on physical health is to remain as physically active as possible.
This research confirms the importance of physical activity for healthy aging. Staying active and fit, regardless of one’s body type, will have protective benefits that will help reduce the risks of functional loss and disability.
