Malnourished patients were more often frail than those at risk (60 (30.8%) vs. 30 (15.4%), p<0.001). Self-reported functional limitations were more pronounced in malnourished patients (17.3 ± 6.2 vs. 14.3 ± 5.6 from max 30 points, p=0.001), while quality of life did not differ (EQ5D5L-Index and EQ-VAS). The majority of patients reported having problems in all dimensions of the EQ5D5L. Malnourished patients had objectively measured as well as subjectively reported limitations at hospital discharge but did not differ in quality of life compared to patients with nutritional risk.

Tooth loss, a major element of oral frailty, is mainly caused by periodontal disease and is an irreversible event. Therefore, this study aimed to clarify whether advanced periodontal disease increases the risks of “new-onset” oral frailty through a longitudinal analysis based on the 2012 baseline survey of the Kashiwa cohort and the follow-up assessments conducted in 2013, 2014, 2016, and 2018. The participants were disability-free, non-orally frail older adults living in Kashiwa City. Of the 1234 participants (72.2 ± 5.1 years old; 50.8% men) analyzed in this study, oral frailty occurred in 23.1% within the six-year period. The group with Community Periodontal Index (CPI) ≥ 3 at baseline had no significant difference in the risk of oral frailty compared with CPI ≤ 2; however, CPI4 at baseline was rela...

We have previously developed an Oral Frailty Index (OFI-8) to identify older adults at risk of oral frailty. Herein, we aimed to examine whether OFI-8 scores are indicative of oral frailty or functional disability risk in community-dwelling older adults. METHODS A total of 2,011 individuals (51% women; mean age, 73.0 ± 5.5 years) participated in the 2012 baseline survey (last follow-up wave 2018). Oral frailty was assessed at each time point, based on tooth status, oral function, and other subjective measures. Functional disability was defined as long-term care certification granted during 2012-2019. The OFI-8 items were assessed at baseline. RESULTS The prevalence and incidence rates of oral frailty at baseline and 6 years were 16% and 24%, respectively. The area under the receiver operating characteristic curve of OFI-8 was 0.88 with 95% confidence interval of 0.86-0.90 for oral frailty. The OFI-8 score of ≥4 points maximized the sum of sensitivity and specificity values. The corresponding positive rate, sensitivity, specificity, positive, and negative predictive values were 30%, 80%, 80%, 43%, and 95%, respectively, for baseline oral frailty. A 1-point increase in the OFI-8 score corresponded to a 1.3-fold increase in the risk of new-onset oral frailty and 1.1-fold increase in the risk of disability. CONCLUSIONS OFI-8 may help identify individuals at risk of oral frailty and functional disability. It may also increase the awareness of oral care and facilitate its uptake.

Because it is reported that accumulated declines in multiple oral functions (i.e. oral frailty) could lead to frailty progression, detailed countermeasures for oral frailty are currently required. However, dentists of community dental clinics don’t even know a prevalence of oral frailty among outpatients. Thus, we aimed to identify the prevalence of oral frailty and to examine the association with frailty in outpatients at community dental clinics. Methods The subjects were elderly outpatients at dental clinics in Kanagawa, Japan. Frailty was assessed using the Kihon checklists (KCL); those with ≥8 KCL score were classified as frailty. Furthermore, multiple functions (physical, nutrition, and oral) were assessed using subscale of the KCL. Oral frailty was defined as ≥3 deteriorations out of 5 oral status (remaining teeth, chewing ability, articulatory oral motor skill, subjective difficulties in eating and swallowing)...

Herein, we examined the relationship between oral frailty and meal satisfaction among community-dwelling older adults. Meal satisfaction was evaluated using self-administered questionnaires. Oral conditions were assessed based on the number of remaining teeth and oral frailty. Of the 940 subjects in the Kashiwa study, which was conducted in the Kashiwa city, Chiba prefecture, Japan, 71% responded that their meals were “tasty” and 96% responded “enjoyable”. Moreover, 23% responded that the amount of meal was “large,” and 63% responded “normal” - While the number of teeth was not significantly associated with meal satisfaction, there was a negative association between oral frailty and meal satisfaction. Our finding indicates that it is important to consider and manage oral functions, other than the number of remaining teeth, to maintain healthy eating habits in older adults.
