Abstract
BACKGROUND: Recent studies have shown that the peripheral inflammation may cause the up-regulation of central nervous system inflammation and therefore possibly plays a vital role in the pathophysiology of subsequent psychiatric disorders.
OBJECTIVE: We explored the relationship between gastroesophageal reflux disease (GERD) and the subsequent development of psychiatric disorders including schizophrenia as well as bipolar, depressive, anxiety, and sleep disorders.
METHODS: We investigated patients who were diagnosed with GERD according to the data in the Taiwan National Health Insurance Research Database. A comparison cohort comprised patients without GERD who were matched according to age and sex. The incidence rate and the hazard ratios (HRs) of subsequent new-onset psychiatric disorders were calculated for both cohorts, based on the diagnoses of psychiatrists.
RESULTS: The GERD cohort consisted of 3813 patients, and the comparison cohort comprised 15,252 matched control patients without GERD. The risks of depressive disorder (HR=3.37, 95% confidence interval [CI]=2.49-4.57), anxiety disorder (HR=2.99, 95% CI=2.12-4.22), and sleep disorder (HR=2.69, 95% CI=1.83-3.94), were higher in the GERD cohort than in the comparison cohort. In addition, the incidence of newly diagnosed depressive, anxiety, and sleep disorders remained significantly increased in all of the stratified follow-up durations (0-1, ≥1year).
CONCLUSIONS: GERD may increase the risks of subsequent depressive, anxiety, and sleep disorders. These psychiatric disorders have a negative effect on people's quality of life. Clinicians should pay a particular attention to psychiatric comorbidities in GERD patients.
