Caregiving and gingival symptom reports: psychophysiologic mediators.

OBJECTIVE: We first assessed the association of caregiving with gingival symptom reports. We then assessed whether the observed relationship was mediated by psychophysiologic host factors. METHODS: Caregivers of spouses with Alzheimer's disease (n = 123) were compared with demographically similar noncaregiver spouses (n = 117). RESULTS: The percentage of caregivers (17%) who reported gingival symptoms was twice that of noncaregivers (8.5%) (p < .05), despite the fact that caregivers and noncaregivers did not differ in oral health care. The relationship between caregiving and gingival symptom reports was mediated by psychophysiologic variables. Caregivers were higher on hassles (p < .05), depressed mood (p < .05), and metabolic risk (insulin, glucose, obesity; p < .05) than were noncaregivers. Greater gingival symptom reports were also associated with greater hassles (p < .01), depressed mood (p < .001), and metabolic risk (p < .001). Measures of subcutaneous fat, inflammation, and frank diabetes were related to gingival symptom reports but not to caregiver status. CONCLUSIONS: A higher percentage of caregivers reported gingival symptoms than noncaregivers. These results have implications for research on aging, psychophysiology, and chronic stress.
