Washington: People living in India experience the health problems associated with ageing at an early stage than those living in Japan or Switzerland, according to a first-of-its-kind study published in The Lancet Public Health.

Researchers at the University of Washington in the US and colleagues found that a 30-year gap separates countries with the highest and lowest ages at which people experience the health problems of a 65-year-old.

 

They found 76-year-olds in Japan and Switzerland, and 46-year-olds in Papua New Guinea have the same level of age-related health problems as an “average” person aged 65.

The analysis also found that people living in India experience the similar health problems well before they turn 60. “These disparate findings show that increased life expectancy at older ages can either be an opportunity or a threat to the overall welfare of populations, depending on the ageing-related health problems the population experiences regardless of chronological age,” said Angela Y. Chang, lead author of the study and postdoctoral fellow at the University of Washington in the US.

“Age-related health problems can lead to early retirement, a smaller workforce, and higher health spending. Government leaders and other stakeholders influencing health systems need to consider when people begin suffering the negative effects of ageing,” Chang said in a statement. These negative effects include impaired functions and loss of physical, mental, and cognitive abilities resulting from the 92 conditions analysed, five of which are communicable and 81 non-communicable, along with six injuries.

The study is the first of its kind, according to Chang. Where traditional metrics of ageing examine increased longevity, this study explores both chronological age and the pace at which ageing contributes to health deterioration.

The study uses estimates from the Global Burden of Disease study (GBD). The researchers measured “age-related disease burden” by aggregating all disability-adjusted life years (DALYs), a measurement of loss of healthy life, related to the 92 diseases.

Although most countries have similar rankings between age-standardised, age related and all-burden rates, countries such as Ethiopia, Nigeria, and South Africa perform better in age-related disease burden relative to all burden.
