    ObjectiveMental, emotional, physical, and general fatigue, as well as vigor, have each been associated with pain interference-defined as pain-related disruption of social, recreational, and work-related activities-in patients with chronic orofacial pain (COFP). The objectives of the current study were to compare levels of these fatigue subtypes across younger, middle-aged, and older patients with COFP and test the associations between fatigue subtypes and pain interference in these age groups.DesignA cross-sectional cohort design was used.SettingParticipants self-reported fatigue subtypes (Multidimensional Fatigue Symptom Inventory-Short Form), pain interference (West Haven-Yale Multidimensional Pain Inventory), pain intensity (visual analog scale), pain duration (months), depression (Symptom Checklist 90-Revised), and sleep quality (Pittsburgh Sleep Quality Index) at their initial appointment at a tertiary orofacial pain clinic.SubjectsSixty younger (age 18-39), 134 middle-aged (age 40-59), and 51 older (age 60-79) COFP patients provided data for the study.MethodsAnalysis of variance was used to compare levels of fatigue subtypes between the age groups. Regression with dummy-coding was used to test if the relationship between fatigue subtypes and pain interference varied by age.ResultsOlder COFP patients reported less general fatigue and more vigor than younger or middle-aged adults. Fatigue subtypes were each associated with greater pain interference, but associations became nonsignificant after controlling for depression, sleep, and pain intensity/duration. Age group-by-fatigue subtype interactions were not observed.ConclusionsManaging fatigue may be important to reduce pain interference in COFP populations and may be accomplished in part by improving depression and sleep.© The Author(s) 2020.
