Abstract

Objective: Low income is known to be associated with having arthritis. However, no longitudinal studies have documented the relationship between developing arthritis and falling into poverty. This paper focuses upon Australians who develop arthritis to determine if they have an elevated risk of falling into poverty.

Methods: Survival analysis using Cox regression models applied to nationally representative, longitudinal survey data between the years 2007 and 2012 for Australian adults aged 21 years and over.

Results: The hazard ratio for falling into income poverty for females who develop arthritis is 1.51 (95% CI: 1.50 – 1.53), and for males the hazard ratio for falling into income poverty is 1.22 (95% CI: 1.21 – 1.23), relative those who never developed arthritis. The hazard ratio for falling into multidimensional poverty for females who develop arthritis is 1.87 (95% CI: 1.84 – 1.90) and for males the hazard ratio is 1.29 (95% CI: 1.29 – 1.30).

Conclusion: Developing arthritis increases the risk of falling into income poverty and multidimensional poverty. The risk for income and multidimensional poverty is higher for females. Given the high prevalence of arthritis, the condition is an overlooked driver of poverty.
