Abstract
To examine the effects of natural disasters on rheumatoid arthritis (RA) patients we conducted a questionnaire survey targeted to 1,477 members of a nationwide RA patient group in Japan who lived in the municipalities affected by natural disasters between 2004 and 2006. Functional statuses measured by the modified Health Assessment Questionnaire and self-rated health statuses before and after the events were retrospectively examined. The associations between the changes in functional and health status and socio-demographics, direct damage, and preparedness status were statistically analyzed. Of the 665 individuals who responded, the data on 192 women RA patients were analyzed. The values at 1 and 6 months post-event were the same, with 14% experiencing deteriorations of functional status, while 22% experienced a worsening of self-rated health status. Those in poorer functional status before the events were more likely to experience deteriorations of functional [odds ratio (OR) 4.4, 95% confidence interval (CI) 1.5–13.6] and health (OR 2.8, 95% CI 1.2–6.7) status at both 1 month and 6 months (OR 3.9, 95% CI 1.3–12.0, and OR 2.8, 95% CI 1.2–6.7, respectively) after the events. Based on these results, we conclude that the functional and health status of women RA patients could worsen due to the consequences of a natural disaster, with a disproportionately large impact upon those with a poorer functional status.
