Analysis of moment structures for assessing relationships among perceived chewing ability, dentition status, muscle strength, and balance in community‐dwelling older adults

Abstract

The findings observed in this study present a possible importance of dental status and perceived chewing ability for the onset of disability by influencing physical performance in community-dwelling older adults.

Relationship between chewing ability and sarcopenia in Japanese community‐dwelling older adults

“…Several studies have reported on the relationship between chewing ability and grip strength/physical performance, and on the relationship between tongue muscle thickness and sarcopenia, but there have been no reports addressing the possible relationship between chewing ability and sarcopenia.…”

Relationship Between Self-Rated Masticatory Ability and Independent Life in Community-Dwelling Older Adults

“…Another recent study reported a relationship between certification of long-term care insurance and self-rated chewing ability. The result of the Kaplan–Meier analysis for individuals aged 65 to 79 years clearly demonstrated that the proportion of individuals not certified for long-term care insurance significantly declines in those with self-rated fair or poor masticatory ability compared with those having good mastication (Moriya, Notani, Murata, Inoue, & Miura, 2014). A Cox proportional hazard analysis also shows that the certification for long-term care insurance was 1.87-fold (CI = [1.07, 3.27]) higher in the individuals with fair or poor masticatory ability in comparison with those with adequate ability (Moriya et al, 2014).…”

A 6-year follow-up study on rural community–dwelling older adults in Japan by Shinkai et al (2003) demonstrated that depression of basic activity of daily living (ADL) and iADL were 1.88-fold (CI = [1.26, 2.82]) and 2.22-fold (CI = [1.50, 3.27]), respectively, higher in individuals with poor chewing ability in comparison with those with better ability.…”

Masticatory efficiency contributing to the improved dynamic postural balance: A cross‐sectional study

“…Takata et al identified a relationship between postural balance and masticatory ability by evaluating by the number of chewable foods; their study suggested that higher masticatory ability is associated with better posture. Additionally, Moriya et al found a positive correlation between self‐assessed masticatory ability and postural balance; relationships have also been reported between postural balance and various factors: perceived chewing ability, dentition status and muscle strength …”

“…To more objectively evaluate dynamic chewing behaviour, this study used the mixing ability index (MAI) to quantitatively measure masticatory function. Additionally, postural balance has largely been assessed using static methods; for example, prior studies have measured the duration for which participants can maintain balance while standing on one leg . However, postural balance can be assessed using static and/or dynamic methods.…”
