Long-term sickness absence and disability pension with psychiatric diagnoses: A population-based cohort study

Gjesdal, Sturla, Ringdal, Peder R., Haug, Kjell, Gunnar Mæland, John·2008·Nordic Journal of Psychiatry

Abstract

Sickness absence certified with psychiatric diagnoses is increasing in many Western countries. A substantial proportion of the sickness absentees never return to work, but ends up with a permanent disability pension (DP). This study investigated the incidence of long-term sickness absence (LTSA) with different psychiatric diagnoses, and tested predictors of the transition to permanent DP. A special objective was to explore previously reported gender differences, using a population-based cohort study. The population at risk of LTSA was 106,674 occupational active men and 89,356 women in a Norwegian county in 1994; 314 women and 203 men with LTSA >8 weeks, certified with a psychiatric diagnosis, were followed to the end of 1999, with DP as the endpoint. Diagnoses on sickness certificates, age, gender and income were used as explanatory variables in Cox regression analysis. Annual incidence of LTSA with a psychiatric diagnosis was 7.0/1000/year for women and 3.8/1000 for men; 72% of the women and 50% of the men had a diagnosis indicating depression. During follow-up, 32% of the men and 25% of the women obtained DP. Increasing age, male gender, low income and a diagnosis of psychosis or "other" increased the DP risk. Separate analysis for men indicated a different effect of age and a larger role of serious mental illness. The study verified that women more often than men had LTSA with psychiatric diagnoses, especially with depression. Men were at higher risk of transition to DP, and the study suggested some possible explanations.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Common mental disorders are among the most important predictors of disability pensioning, especially in younger age groups, and associations are significant regardless of whether pensions are awarded for somatic or psychiatric disorders.

    “Common mental disorders are among the most important predictors of disability pensioning [3–6]; especially, in the younger age groups [7], and associations are significant regardless of whether the pensions are awarded for somatic or psychiatric disorders [8].”
  • Adjusting for mood and anxiety disorders may be overly conservative because personality disorder symptoms overlap with anxiety and depression, potentially underestimating the true effects of personality disorders.

    “The symptoms might therefore work as mediators instead of confounders, making the adjustments overly conservative and underestimating the true effects of PDs.”
  • Personality disorders are highly co-morbid with anxiety and depression, and these disorders are known to be associated with increased risk of disability pensioning.

    “PDs are highly co-morbid with anxiety and depression [35–38], and these disorders are known to be associated with an increased risk of disability pensioning [3–6].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
