Abstract

<abstract abstract-type="main"> <title>Summary</title> <p>This study investigated whether the complaint of night‐time heartburn (NHB) as opposed to daytime heartburn (DHB) is a reliable reflection of actual sleep‐related reflux events. Three groups of individuals were studied: individuals with complaints of NHB at least twice per week (<italic>n</italic> = 24), individuals with complaints of DHB (<italic>n</italic> = 23), and normal participants without any complaints of regular heartburn during the day or night (<italic>n</italic> = 25). All three groups were studied on one occasion with combined pH monitoring and polysomnography, and subjective questionnaires about sleep disturbance and sleep quality were given to all participants. The NHB group had significantly more sleep‐related reflux events compared with both DHB and control groups (<italic>P</italic> < 0.01). DHB subjects had significantly (<italic>P</italic> < 0.05) more sleep‐related reflux events than normal controls. Total acid contact time (ACT) was significantly (<italic>P</italic> < 0.05) elevated in the NHB group compared with both the DHB and control group. Sleep‐related ACT was also significantly (<italic>P</italic> < 0.05) elevated in the NHB group compared with the other two groups, while upright (daytime) ACT was not significantly different. The NHB group was significantly (<italic>P</italic> < 0.05) worse regarding measures of both objective and subjective sleep quality. Subjects with exclusively DHB do have sleep‐related reflux that is greater than normal controls. Subjects with NHB have significantly more sleep‐related reflux, and both objective and subjective sleep abnormalities compared with normal controls. Complaints of NHB reflect sleep‐related reflux events and may be indicative of a more clinically significant condition.</p> </abstract>
