Medical comorbidity and health-related quality of life in bipolar disorder across the adult age span.
ABSTRACT Little is known about medical comorbidity or health-related quality of life (HRQOL) in bipolar disorder across the adult age span, especially in public sector patients.
We obtained cross-sectional demographic, clinical, and functional ratings for 330 veterans hospitalized for bipolar disorder with Mini-Mental State score > or = 27 and without active alcohol/substance intoxication or withdrawal, who had had at least 2 prior psychiatric admissions in the last 5 years. Structured medical record review identified current/lifetime comorbid medical conditions. SF-36 Physical (PCS) and Mental (MCS) Component Scores, measured physical and mental HRQOL. Univariate and multivariate analyses addressed main hypotheses that physical and mental function decrease with age with decrements due to increasing medical comorbidity.
PCS decreased (worsened) with age; number of current comorbid medical diagnoses, but not age, explained the decline. Older individuals had higher (better) MCS, even without controlling for medical comorbidity. Multivariate analysis indicated association of MCS with age, current depressed/mixed episode, number of past-year depressive episodes, and current anxiety disorder, but not with medical comorbidity, number of past-year manic episodes, current substance disorder or lifetime comorbidities.
This cross-sectional design studied a predominantly male hospitalized sample who qualified for and consented to subsequent randomized treatment.
Medical comorbidity is associated with lower (worse) physical HRQOL, independent of age. Surprisingly, younger rather than older subjects reported lower mental HRQOL. This appears due in part to more complex psychiatric presentations, and several mechanisms are discussed. Both results suggest that age-specific assessment and treatment may enhance HRQOL outcome.

ABSTRACT: Little is known about quality of life (QOL) in Chinese patients with bipolar disorder (BD) in remission (euthymia). This study examined the QOL of such a cohort of BD patients and its demographic, clinical, and cognitive correlates. Forty-seven euthymic BD patients and 47 matched healthy controls formed the study sample. Socio-demographic characteristics, prospective memory, retrospective memory, intelligence quotient, and executive functioning were measured in all participants together with patients' psychopathology ratings. Multivariate analyses revealed that compared to controls, euthymic BD patients had significantly lower satisfaction with physical QOL domain. Only subthreshold depressive symptoms independently contributed to reduced satisfaction with physical and environmental QOL domains, whereas no variable predicted its psychological and social domains. Contrary to findings from Western settings, demographic variables and cognitive deficits had no associations with any QOL domain in euthymic Chinese BD patients. Control of subthreshold depressive symptoms in euthymic BD patients might enhance their QOL.Perspectives In Psychiatric Care 05/2013; 50(1). DOI:10.1111/ppc.12024 · 0.71 Impact Factor

ABSTRACT: Health-related quality of life (HRQOL) is a widely accepted measure of illness state that is related to morbidity and mortality. Findings from various populations show that women report lower HRQOL than men. We analyzed baseline HRQOL data for gender differences from a multisite, randomized controlled study for adults with bipolar disorder. HRQOL was assessed using the 12-item Short Form (SF-12) physical component summary (PCS) and mental component summary (MCS) health scales. Multivariate linear and bivariate regression models examined differences in self-reported data on demographics, depressive symptoms (nine-item Patient Health Questionnaire), bipolar disorder symptoms (Internal State Scale), and medical comorbidities. Out of 384 enrolled (mean age = 42 years), 256 were women (66.7 %). After controlling for sociodemographic characteristics and clinical factors, women had lower SF-12 PCS scores than men [β = -1.78, standard error (SE) = 0.87, p < 0.05], indicating worse physical health, but there were no gender differences in MCS scores. After controlling for patient factors including medical and behavioral comorbidities, the association between gender and PCS score was no longer significant. Of the medical comorbidities, pain was associated with lower PCS scores (β = -4.90, SE = 0.86, p < 0.0001). Worse physical HRQOL experienced by women with bipolar disorder may be explained by medical comorbidity, particularly pain, suggesting the importance of gender-tailored interventions addressing physical health conditions.Archives of Women s Mental Health 04/2013; 21(4).

ABSTRACT: BACKGROUND: Evidence suggests that patients with bipolar disorder have an elevated risk for comorbid posttraumatic stress disorder (PTSD) compared to those without a bipolar diagnosis. Although bipolar disorder is associated with decreased health-related quality of life (HRQOL), it is unclear whether comorbid PTSD interacts to affect HRQOL. METHOD: Baseline data from a multi-site study of patients with bipolar disorder were analyzed. Patient surveys ascertained clinical and demographic information, including physical and mental HRQOL based on the SF-12, mood symptoms (PHQ-9, Internal State Scale), and self-reported co-occurring conditions including PTSD. RESULTS: Overall (N=384), 44.9% of patients self-reported co-occurring PTSD. Patients with PTSD had lower physical and mental HRQOL scores compared to those without PTSD (mean (SD) for those with and without PTSD, respectively): Mental Component Scale score 30.51 (8.22) and 32.86 (8.35); Physical Component Scale score 35.56 (7.77) and 37.21 (7.20). After adjusting for demographic and clinical factors including mood symptoms, multiple linear regression analyses revealed that PTSD was no longer significantly associated with physical or mental HRQOL; however, depressive symptoms were independently associated with mental HRQOL (Beta -0.63, p<0.01). CONCLUSION: Depressive symptoms may explain the association between PTSD and mental HRQOL. Clinicians working with these patients will want to emphasize treatment of depression as important towards improving HRQOL for this group.Journal of Affective Disorders 09/2012; 145(2).
