Postponing retirement by just one year may be associated with an 11% reduced risk of death from any cause, according to a study published in the Journal of Epidemiology and Community Health. The findings suggest that delaying major life milestones, such as leaving the workforce, could have a significant impact on longevity.
The study analyzed data from 2,956 older adults collected between 1992 and 2010 as part of the Health and Retirement Study. This research aimed to describe changes in life patterns around the retirement transition, collecting information on health conditions, social networks, financial status, and employment.
Participants were categorized as either healthy or unhealthy retirees based on their perceived importance of health when considering retirement age. Healthy retirees reported that health was not an important factor in their decision, while unhealthy retirees indicated it played a role. Healthy retirees were generally more physically active, less likely to smoke, had lower body mass index, fewer chronic conditions, and better self-reported health compared to the unhealthy group.
The research found that both healthy and unhealthy individuals who retired later experienced lower mortality rates. However, the decrease in all-cause mortality risk was more pronounced for healthy retirees (11%) compared to unhealthy retirees (9%).
While the connection between retirement age and mortality is not fully understood, one theory posits that work provides crucial financial, social, and cognitive resources that contribute to well-being. Retirement, conversely, might lead to increased stress, cognitive decline, anxiety, or depression if these resources are diminished. The study noted that incorporating volunteer opportunities and social activities alongside delayed retirement could help mitigate potential declines.
Previous investigations into populations in Austria, Germany, Greece, Sweden, and the United States have yielded consistent findings regarding the association between retirement age and health outcomes. Experts emphasize that social isolation and loneliness, which can increase after retirement, pose a growing health challenge and may impact the aging process.
