Low income accelerates loss of physical function in the elderly
- Low income accelerates the loss of mobility in the elderly.
- A 60-year-old with low income is comparable to an 80-year-old who is well-off.
- The study covered Britain and Canada, published in PLoS Medicine.
As part of a long-term cohort study involving several thousand older adults in the UK and Canada, researchers examined the relationship between financial well-being and the ability to maintain physical and daily independence. Participants were regularly assessed for mobility, ability to perform daily tasks, and overall functioning.
The data clearly indicate that individuals in the lowest financial quartile show lower results across all measured indicators. This applies to both basic physical abilities – walking, climbing stairs – and more complex daily skills, such as cooking or managing household appliances.
The rate of decline in mobility
The increase in the pace of mobility deterioration among participants with limited income was particularly noticeable. During the observation period, they lost the ability to move independently on average 30% faster than their more affluent peers. This leads to an increase in dependence on external assistance and raises the risk of falls.
Analysis of daily household tasks showed that people with low income experience a decline in their ability to perform routine actions almost twice as fast. For example, the ability to cook independently, maintain cleanliness in the apartment, or use household appliances deteriorated noticeably faster in the group with limited financial resources.
An interesting comparison from the study was that a 60-year-old person with a low income had the same level of household skills as a wealthy 80-year-old. This highlights that financial inequality can 'accelerate' biological age, making people more vulnerable to loss of independence.
The study was published in PLoS Medicine and is supported by a statistical analysis that takes into account age, gender, the presence of chronic diseases, and other potential factors. The authors emphasize that financial status remains an independent predictor of functional decline, even after adjusting for other variables.
The results have important practical implications. They indicate the need for the development of social programs aimed at supporting low-income elderly individuals, including financial assistance, access to rehabilitation services, and programs to maintain activity. Without such measures, age groups with limited resources may face accelerated deterioration in quality of life and an increased burden on the healthcare system.
