Relationship between gastroesophageal reflux disease and objective sleep quality.

STUDY

OBJECTIVES

To objectively characterize (1) the relationship between gastroesophageal reflux disease (GERD) and sleep quality, and (2) the influence of sleep position on this relationship, using in-laboratory polysomnography.

METHODS

We retrospectively analyzed first-night diagnostic in-laboratory polysomnography data for 3411 patients (median age 55 years; 48% male). Medication use and medical condition data were obtained through self-reported questionnaires. Associations between sleep quality and the presence of GERD, and the influence of sleep position on these associations, were analyzed using multivariable linear regression models.

RESULTS

After adjusting for age, sex, body mass index, and relevant comorbidities, GERD was associated with a 3.0% decrease in sleep efficiency, 8.8-minute increase in wake after sleep onset, 24.4-minute increase in rapid eye movement (REM) latency, 13.4-minute decrease in total sleep time, 1.4% decrease in %REM sleep, and 1.5% increase in %N3 sleep. Having both GERD and the majority of sleep on the right side was associated with an 8.6% decrease in sleep efficiency, 27.5-minute increase in wake after sleep onset, 35.6-minute decrease in total sleep time, 2.1% decrease in %REM sleep, and 3.5% increase in %N3 sleep. Having both GERD and the majority of sleep on the left side was associated with an 8.7-minute increase in sleep onset latency.

CONCLUSIONS

GERD is associated with an impairment in objective sleep quality. These associations were more pronounced in right-sided sleep and mostly ameliorated in left-sided sleep. Physicians should recognize the potential for poor sleep quality in patients with GERD and the effect of body position on this relationship.
