Walking Activity and Healthcare Spending
A large study involving more than 20,000 adults in Japan has examined the relationship between daily walking activity and future healthcare spending. The research found that people with lower daily step counts tended to have higher predicted medical costs over the following six months.
Researchers analysed data from 20,950 residents aged 40 and above. The information combined daily step counts recorded through a health app with healthcare expenditure records collected between 2020 and 2023.
Findings Show a Non-Linear Pattern
The analysis found that predicted healthcare spending generally declined as daily step counts increased from lower activity levels. However, the relationship did not continue in a straight line. The estimated costs began to level off around 11,000 steps per day, rather than continuing to fall substantially with every additional step.
The pattern was broadly similar among middle-aged and older participants, although the estimated healthcare costs were considerably higher among older adults.
Researchers Highlight the Study’s Limitations
The researchers stressed that the findings show an association, not proof that walking more directly reduces an individual’s medical expenses. The study also involved people who regularly used a health app, so its results may not represent the entire population.
The research offers another perspective on how everyday physical activity relates to health and healthcare systems. It does not establish 11,000 steps as a necessary daily target for everyone.
