Association of current and remitted bipolar disorders with health-related quality of life: Findings from a nationally representative sample in the US

Abstract

Background: The associations of current and remitted bipolar disorder (BD) with health-related quality of life (HRQOL) have been under-studied, and we aim to address these gaps.

Methods: The 2012-2013 National Epidemiological Survey on Alcohol and Related Conditions III (NESARC III) surveyed a nationally representative sample of non-institutionalized adults in the US. Using DSM-5 criteria, three groups were operationalized as: 1) adults who met criteria for BD in the past year (i.e., current BD; n = 566 unweighted); and 2) adults who met criteria for BD previously but not in the past year (i.e., BD in remission; n = 187); and 3) adults with no BD in their lifetime (n = 35,556). HRQOL and quality-adjusted life years (QALYs) were compared by these groups. Multivariable-adjusted regression analyses were used to adjust for and examine the role of covariates.

Results: Overall, 1.5 % of the study sample, representing 3.6 million adults nationwide, met criteria for current BD, and 0.5 %, representing 1.3 million adults, met criteria for BD in remission. Adults with current BD and BD in remission had lower mental HRQOL and QALYs, as compared to adults who never had BD. However, these differences were no longer significant when adjusted for behavioral co-morbidities (e.g., psychiatric and substance use disorders).

Conclusion: Both current BD and BD in remission were adversely associated with HRQOL and QALYs, while these associations were not independent of behavioral co-morbidities. Because behavioral co-morbidities are common in individuals with current BD or those with BD in remission, they should be treated together to improve HRQOL.
