"What's Wrong with Getting Old?" Breaking Social Stereotypes Led to Better Health—Here's Why

Positive Perceptions of Aging Linked to Improvements in Physical and Cognitive Function

It is commonly believed that memory and physical abilities decline with age, but a recent study has found that a considerable number of older adults may actually experience improvements in cognitive and physical functions.

On March 5 (local time), Vega Levy, Professor at the Yale School of Public Health in the United States, and her research team announced the results of a 12-year follow-up study of more than 11,000 individuals aged 65 and older. The team found that those who had a positive perception of aging were more likely to experience functional improvements. The findings were published in the international journal 'Geriatrics.'

The researchers conducted a comprehensive assessment of participants' memory and thinking skills to track changes in cognitive function during the aging process. Changes in physical function were measured based on walking speed, which is a representative indicator of health status in older adults.

Analysis showed that 45% of all participants demonstrated improvements in at least one domain—either cognitive or physical function. Specifically, 32% of participants showed improvements in cognitive function, while 28% saw enhancements in physical function. The study also observed functional improvements in participants whose abilities were within the normal range at the start of the research.

The research team noted that individuals' perceptions of aging were a significant variable. The more positively participants viewed aging, the greater the likelihood of improvements in cognitive ability and walking speed. These results remained valid even after adjusting for health-related factors such as age, gender, education level, and chronic diseases.

The researchers explained, "On average, functional decline with aging is common, but a significant number of older adults actually improved their functions." Those who experienced improvements were overshadowed by the average, which contributed to the stereotype that 'old age inevitably means decline.'

These findings support the 'stereotype embodiment theory,' which suggests that societal stereotypes about aging can influence individual health. According to this theory, negative perceptions about aging, when internalized, may adversely affect memory, reduce walking speed, and increase the risk of cardiovascular disease.

The research team emphasized, "Aging is not a process that can be explained only by functional decline," adding, "Simply changing perceptions of aging to be more positive has the potential to improve function."

However, the team cautioned that it cannot be concluded that perceptions of aging are the direct cause of functional improvements. Factors such as exercise, sleep, and social relationships may also play a role, so randomized clinical trials are needed to verify the effects of interventions aimed at changing perceptions of aging.
