%X OBJECTIVE: Psychological distress is considered a factor for cancer development. However, the impact of mood disorders (depression and bipolar) on the development of cervical cancer remains uncertain. We conducted a nationwide population-based retrospective cohort study to investigate the association between mood disorders and the subsequent risk of developing cervical cancer.
METHODS: A total of 138,130 participants' profiles between 2000 and 2012 were extracted from the National Health Insurance Research Database and subdivided into a mood-disorder cohort (27,626 participants) and a non-mood-disorder cohort (110,504 participants). Cohorts were propensity-matched for a 1:4 ratio according to age and index year. The Cox proportional hazards regression model was utilized for assessing cervical cancer risk between cohorts.
RESULTS: Kaplan-Meier analysis revealed that the mood-disorder cohort had a higher cumulative incidence of cervical cancer. The mood-disorder cohort was also associated with an increased risk of cervical cancer after adjustments for potential confounders. Subgroup analysis revealed a negative impact of mood disorders on cervical cancer, especially in the 30-50 years and white-collar groups.
CONCLUSIONS: Our findings demonstrated that mood disorders were associated with an increased risk of cervical cancer development, which provide helpful information for clinical strategies to reduce the incidence of cervical cancer in this vulnerable population.
