Association between carpal tunnel syndrome and the five-year incidence of anxiety disorder and depression in adults followed in general practices in Germany
Little is known about the longitudinal relationship between carpal tunnel syndrome (CTS) and mental health. Therefore, this retrospective cohort study investigated the association between CTS and the five-year incidence of anxiety disorder and depression in adults from Germany.
Data from the Disease Analyzer database (IQVIA) were used for the present study. Patients aged ≥18 years diagnosed for the first time with CTS in one of 1284 general practices in Germany in 2005–2020 were included (index date). Individuals without CTS were matched to those with CTS using a propensity score based on age, sex, the mean number of consultations per year during the follow-up, and the index year. In people without CTS, the index date was a randomly selected consultation in 2005–2020.
There were 75,135 patients with and 75,135 patients without CTS included in the study (mean [SD] age 57.2 [16.5] years; 59.7% women). Within five years of the index date, the incidence of anxiety disorder was 3.9% and 3.6% in the group with and the group without CTS, respectively (log-rank p-value<0.001), while figures for depression were 14.8% and 11.5% (log-rank p-value<0.001). These findings were corroborated in the Cox regression analyses adjusted for multiple physical conditions, as CTS was associated with anxiety disorder (HR = 1.14, 95% CI = 1.08–1.21) and depression (HR = 1.29, 95% CI = 1.25–1.33) in the overall sample.
CTS was associated with an increased incidence of anxiety disorder and depression in Germany. Further research should identify the mediators involved in these relationships.
