title: Low socioeconomic position and depression persistence: longitudinal results from the GAZEL cohort study.
abstract: Research examining the association between socioeconomic position and depression course has yielded inconsistent results. We tested the association between low socioeconomic position and 7-year depression persistence among 298 community-based individuals with depression (subset of the GAZEL cohort study based in France). Data were analyzed using Generalized Estimating Equation (GEE models). Low socioeconomic position predicted depression persistence (men: low vs. intermediate/high income: OR: 2.52, 95% CI 1.28-4.95; women: low vs. intermediate/high occupational grade: OR: 2.25, 95% CI 1.06-4.80). These associations were reduced and became statistically nonsignificant after controlling for baseline sociodemographic characteristics and stressful life events (men and women), overall health (men), and the severity of mental health difficulties (men and women). Overall, depressed individuals with low socioeconomic position appear disproportionately likely to experience multiple risk factors of long-term depression.
