Formal retirement and multidimensional health among middle-aged and older adults in China: a five-wave within-person analysis of the China Health and Retirement Longitudinal Study
This five-wave longitudinal study of Chinese adults finds that formal retirement is most consistently associated with increased physical activity and, specifically among women, reduced limitations in activities of daily living, while showing no significant impact on cognitive performance.

Retirement is often imagined as a single, sharp line in the sand: one day you work, and the next you stop. For many, this transition promises a new chapter of leisure and health, while for others, it brings the fear of losing purpose and routine. In reality, the shift is rarely so clean. People stop working for different reasons, at different ages, and under different rules. In China, where the population is aging rapidly and the government is gradually raising the official age at which people can retire, understanding what happens to a person's health when they officially leave the workforce is a pressing question. Researchers are particularly interested in whether stepping away from a job helps people move more, think sharper, and feel better, or if it leads to a decline in these areas. The answer is not simple, because leaving a job changes a person's daily schedule, their social contacts, and their physical demands in ways that can be both helpful and harmful.
To untangle these effects, a team of researchers turned to a massive, long-term study of Chinese adults known as the China Health and Retirement Longitudinal Study. They looked at nearly twenty-six thousand people over a nine-year period, tracking them through five different check-ins between 2011 and 2020. The goal was to see what happens to the same person before and after they officially retire. The researchers focused on "formal retirement," which means the person has completed the official paperwork to leave their job and receive a pension, rather than just stopping work informally. They measured several aspects of health: how difficult it was for people to perform basic daily tasks like bathing or dressing, whether they engaged in any physical activity like walking or exercising, and how well they could perform a mental task that involved subtracting seven from a number repeatedly. They also looked at mood, sleep, and memory. By comparing a person to themselves over time, the study could isolate the changes that happened specifically around the time of retirement, rather than just differences between people who retire and those who do not.
The results revealed a clear pattern, but it was not the same for everyone. For women, retiring formally was linked to a noticeable improvement in their ability to move and function. On average, women who retired reported fewer difficulties with daily tasks, such as getting out of bed or controlling their bathroom needs. They were also more likely to say they were doing some form of physical activity, whether it was walking, gardening, or exercising. This suggests that for many women, leaving the workforce freed up time or reduced physical strain, allowing them to be more active and maintain their physical strength. The study found that this increase in physical activity might explain a small part of why their daily functioning improved, but other factors likely played a role as well.
For men, the picture was different. The study did not find strong evidence that formal retirement changed their physical activity levels or their ability to perform daily tasks. While men did show a slight increase in the likelihood of being active, the change was not as distinct or consistent as it was for women. This difference may stem from the fact that women in China have historically carried a heavier load of unpaid domestic and caregiving work, so leaving a job might free up more time for them to engage in health-promoting activities. It could also reflect differences in the types of jobs men and women held before retiring.
When it came to the mind, the findings were more ambiguous. The researchers tested whether retirement affected a person's ability to concentrate and calculate by asking them to subtract seven from one hundred, five times in a row. Overall, the study found no clear evidence that retiring changed this mental performance. For women, there was a tiny, barely noticeable dip in scores right around the time they retired, but this did not grow into a steady decline over the following years. The researchers concluded that there is no strong proof that retirement causes a loss of mental sharpness, nor is there proof that it boosts it. The mental task used in the study is a specific test of calculation and attention, and it does not capture the full range of how a person's thinking abilities change with age.
The study also looked at other factors like sleep, mood, and memory, but found no consistent links to retirement. People did not sleep significantly more or less, nor did they report feeling more or less depressed after leaving their jobs. The researchers were careful to note that their data only showed associations, not strict causes. For instance, it is possible that people who were already feeling physically better were the ones who chose to retire, rather than retirement itself making them feel better. However, by tracking the same people over time, the study provided a much clearer view than previous research that simply compared different groups of people at a single point in time.
Ultimately, this research suggests that retirement is not a single event that automatically makes people healthier or sicker. Instead, it is a transition that creates an opportunity. For women in China, stepping away from formal work appears to open a window where they are more likely to move their bodies and maintain their daily independence. For men, the changes are less obvious. The study does not support the idea that retiring early is a guaranteed path to better health, nor does it suggest that working longer is harmful. Instead, it points to retirement as a moment where public health programs could step in. By offering activities that combine movement, social connection, and mental engagement right around the time people retire, communities might help more adults, especially women, make the most of this new phase of life. The findings remind us that the impact of leaving a job depends heavily on who you are, what you did before, and what you choose to do next.
