Physical health comorbidities in older adults with bipolar disorder: A systematic review

Objective: To ascertain the prevalence and predictors of physical health comorbidities in older adults with bipolar disorder.Methods: The authors conducted a systematic review and narrative synthesis of peer-reviewed journal articles reporting on physical health comorbidities in older adults (aged >= 50) with a diagnosis of bipolar disorder. The Mixed Methods Appraisal Tool (MMAT) assessed study quality.Results: 23 papers reporting on 19 studies met the inclusion criteria. The literature on diabetes, obesity and renal disease was inconclusive. There was some tentative evidence to higher rates of cardiovascular disease and some forms of cancer in older adults with bipolar disorder in comparison to the general population, but this requires further investigation. We identified no studies looking at oral health.Limitations: The quality ratings of the identified research were generally low. Very few studies included a comparison sample from the general population or controlled for key covariates in their analysis.Conclusion: Existing literature provides tentative evidence that some physical health comorbidities are elevated in older adults with bipolar disorder. Clinicians should consider interventions that improve the physical health of this group, alongside the chronic mental health difficulties they experience.
