Subjective cognitive complaints and dental clinic visits: A cross‐sectional study from the Japan Gerontological Evaluation Study

Abstract

AimWe investigated the association between subjective cognitive complaints (SCCs) and dental visits in older Japanese adults.MethodsThis was a cross‐sectional study from the Japan Gerontological Evaluation Study (carried out in 2019). The participants were independent older adults aged ≥65 years without dementia. The presence/absence of dental treatment visits and dental checkup visits within the past 12 months were used as outcome variables. The SCC score measured using the Kihon Checklist was set as the explanatory variable. Possible confounders were also included as covariates. Prevalence ratios and 95% confidence intervals were estimated using a Poisson regression model.ResultsThe mean age was 74.1 years (standard deviation 6.0 years). Among the 19 677 eligible participants, 12 359 (62.8%) had dental treatment visits and 11 063 (56.3%) had dental checkup visits. Of these, 5966 (30.3%) had an SCC score of ≥1. The proportion of participants with dental treatment and dental checkup visits within the past 12 months was 63.2% and 56.7% among those with SCC score = 0, and 52.8% and 35.2% among those with SCC score = 3, respectively. In the fully adjusted model, no significant association was observed for participants with SCC scores of 1 and 2. Those with SCC score = 3 had less frequent dental checkup visits (prevalence ratio 0.74, 95% confidence interval 0.57–0.95).ConclusionsOur study highlights that SCC was not associated with limited access to dental care among those with mild SCC. However, those with the highest SCC score seemed to have disturbed access to dental care. Geriatr Gerontol Int 2022; 22: 773–778.
