Key Points

A groundbreaking AI-powered study has uncovered critical insights into the global rise of rheumatoid arthritis since 1980. Researchers found that demographic aging and increased smoking are primary drivers of the disease's growing burden across different regions. The study highlights significant disparities in healthcare infrastructure and disease impact, particularly among younger populations. By 2040, researchers predict continued shifts in rheumatoid arthritis prevalence, with low-middle sociodemographic index regions potentially experiencing increased disease burden.

Ageing population, smoking behind surge in global rheumatoid arthritis since 1980: Study

AI study reveals rising rheumatoid arthritis burden worldwide, highlighting demographic shifts and lifestyle factors from 1980-2021

New Delhi, June 16

An increase in the elderly population as well as a rise in smoking are behind the surge in the global rheumatoid arthritis burden since 1980, according to an AI-powered study.

Rheumatoid arthritis is a chronic autoimmune disease that primarily affects joints, causing pain, swelling, and stiffness.

The novel analysis published in the Annals of the Rheumatic Diseases details significant socioeconomic disparities and worsening inequalities in disease burden.

The findings revealed that demographic ageing, population growth, and uneven healthcare infrastructure exacerbate rheumatoid arthritis burdens differently across regions.

Using data from the Global Burden of Disease (GBD), the study integrated the largest spatiotemporal rheumatoid arthritis dataset spanning 953 global to local locations from 1980 to 2021 with a novel deep learning framework.

It showed that from 1980 to 2021, the global rheumatoid arthritis burden kept rising. The increase was significant among younger age groups and a wider range of geographic locations worldwide.

Notably, disability-adjusted life years (DALYs)-related inequality surged 62.55 per cent from 1990, with Finland, Ireland, and New Zealand as the most unequal countries in 2021.

Economic factors were not found as the sole determinants of rheumatoid arthritis disease burden.

High sociodemographic index (SDI) regions such as Japan and the UK exhibited contrasting patterns in disease burden.

Japan's declining DALY rates despite high SDI may reflect nationwide early diagnosis programmes, widespread use of biologic therapies, and a diet rich in anti-inflammatory components.

"By 2040, low-middle SDI regions may see increasing DALYs due to ageing/population growth, while DALYs in high SDI areas may decrease," said the researchers led by Queran Lin, principal investigator from Imperial College London.

"Controlling smoking may reduce rheumatoid arthritis deaths by 16.8 per cent and DALYs by 20.6 per cent in high-smoking regions (for example, China), offering significant benefits for medium/high SDI areas," said the team.

The researchers said that many regions around the world still lack the necessary evidence base to inform precision health policy and targeted interventions.

This is concerning for India too. We have a growing elderly population and smoking is still very common, especially in rural areas. The government should launch awareness campaigns about the link between smoking and arthritis. Prevention is better than cure! 🙏

Interesting how Japan is managing this better despite having an ageing population. Maybe we should study their healthcare model and dietary habits. Our traditional Indian diet with turmeric and ginger already has anti-inflammatory properties - we should promote this more!

My mother suffers from rheumatoid arthritis and it's heartbreaking to see her in pain daily. The cost of treatment is so high in private hospitals. Government hospitals need more specialists and better medicines for this condition. This study shows it's only going to get worse 😔

While the study is comprehensive, it seems to overlook cultural factors. In India, many elderly continue physical labor well into old age which may aggravate joint issues. Also, tobacco consumption in forms like gutka is a big problem that needs addressing along with cigarettes.

The Ayush ministry should collaborate with modern medicine to develop affordable treatments. Yoga has shown benefits for arthritis patients - maybe we need more research on integrating traditional and modern approaches. After all, prevention is key! 🧘‍♀️

The China smoking statistic is alarming - 20% reduction possible just by controlling smoking! India should take note. We need stricter enforcement of anti-smoking laws and higher taxes on tobacco products. Health warnings on packets aren't enough anymore.
