Remission from Depression among Adults with Arthritis : A 12-Year Followup of a Population-Based Study

Abstract EN

Individuals with arthritis are vulnerable to depression.

In this study, we calculated time to remission from depression in a representative community-based sample of depressed Canadians with arthritis who were followed for 12 years.

We conducted secondary analysis of a longitudinal panel study, the National Population Health Survey, which was begun in 1994/95 and has included biennial assessment of depression since that time.

Our analysis focused on a total of 216 respondents with arthritis who were depressed at baseline.

The mean time to remission from depression was calculated using the Kaplan-Meier procedure and compared across categories of each of the potential predictors.

The percentage of those no longer screening positive for depression was calculated at two years after baseline.

At two years after baseline, 71% of the sample had achieved remission from depression.

Time to remission was significantly longer for those depressed adults who were under the age of 55, those who reported more chronic pain at baseline, those with comorbid migraine, and those who experienced childhood physical abuse or parental addictions.

These findings highlight the importance of screening for these factors to improve the targeting of interventions to depressed patients with arthritis.
