Abstract
En 中文
The diagnosis of bipolar disorder (BD) often faces delays in Chinese patients, affecting treatment outcomes. This study examines the factors associated with the interval from first psychiatric consultation to BD diagnosis and its association with 9-month depressive and manic symptom change. Data from a multicenter study in China was analyzed, involving 520 BD patients (399 type I BD [BD-I] and 121 type II BD [BD-II]) from seven medical institutions. We assessed sociodemographic and clinical features contributing to delayed BD diagnosis and the consequences of long DUBD on manic and depressive symptoms over a 9-month follow-up period. The median DUBD was 0.78 years; 0.51 years for BD-I and 1.59 years for BD-II. Younger age at first psychiatric consultation and older age at the first visit for the BD event were associated with long DUBD in both BD-I and BD-II. In BD-I, higher education level and manic/hypomanic/mixed polarity of first episode were associated with lower odds of long DUBD. Over the 9-month follow-up, longer DUBD was associated with less improvement in depressive symptoms among patients with BD-II. DUBD and its associated factors differed between BD subtypes. Longer DUBD was associated with less improvement in depressive symptoms among patients with BD-II over 9 months.
