Background: Frailty is a major health concern among older adults, and its association with oral health-related quality of life (OHRQoL) remains underexplored in longitudinal studies.
Objective: To investigate the association between baseline OHRQoL and physical frailty incidence at a 2-year follow-up in community-dwelling older adults.
Design: Prospective longitudinal study.
Setting: The study was conducted within the Tosa Longitudinal Aging Study framework in Japan.
Participants: This study included 144 community-dwelling older adults (50 men and 94 women; median age, 81.0 years) with complete data who participated in the Tosa Longitudinal Aging Study in 2016 and 2018 and were not categorized as physical frailty in 2016.
Measurements: Baseline assessment included OHRQoL, which was evaluated using the General Oral Health Assessment Index (GOHAI; range 12-60), with higher scores indicating better OHRQoL, oral function, and general health status. The incidence of physical frailty was defined using the revised Japanese version of the Cardiovascular Health Study criteria. The association between the GOHAI score and physical frailty was assessed using logistic regression analysis.
Results: The median baseline GOHAI score was 58. The incidence of frailty after a 2-year follow-up was 13.9 % among the participants (18.0 and 11.7 % for men and women, respectively). Each point of the GOHAI score was associated with an 11 % reduction in frailty risk over 2 years after adjusting by age, sex, number of teeth, Food Diversity Score, Geriatric Depression Scale score, eating alone, smoking, and more than five medications (adjusted odds ratio: 0.893; 95 % confidence interval: 0.810-0.984).
Conclusions: This longitudinal study showed that a higher baseline OHRQoL, based on the GOHAI score, was linked to a lower incidence of physical frailty among community-dwelling older adults after 2 years.

Background: Frailty is a geriatric syndrome of significant public health concern that causes vulnerability to physiologic stressors and an increased risk of mortality and hospitalizations. Dietary intake and quality are contributing factors to the development of frailty. The Mediterranean diet is known to be one of the healthiest eating patterns with promising health impacts for prevention.

The loss of skeletal muscle mass and strength, known as sarcopenia, is prevalent in older adults and linked to an increased risk of disability, frailty, and early mortality. Muscle health is crucial for the functionality and independence of older adults. As the aging population continuously grows, finding cost-effective strategies for preventing and treating sarcopenia is an important public health priority.

Frailty and severe aortic stenosis (AoS) are critical conditions in older adults, both of which share pathophysiological mechanisms including chronic inflammation and calcium metabolism dysregulation, potentially influencing the development and progression of these conditions. This study aimed to analyze systemic inflammation and calcium homeostasis biomarkers and their associations with frailty in older adults with severe AoS. : This prospective study included 191 patients aged ≥75 years with severe AoS who were candidates for aortic valve replacement and were evaluated at a Geriatrics Frailty Assessment and Intervention Clinic.

The aim of this study was to compare balance, fear of falling, and dual-task performance in frail, pre-frail, and non-frail individuals with type 2 DM. The study included 110 voluntary individuals diagnosed with type 2 DM. Individuals with type 2 DM were divided into three groups according to the FRAIL Scale: frail ( = 26), pre-frail ( = 52), and non-frail ( = 32).

Background/objectives: Frailty is a complex geriatric syndrome resulting in decreased physiological reserve. While genetics plays a role, the underlying mechanisms remain unsolved. Metallothioneins (MTs), metal-binding proteins with high affinity for zinc, an essential mineral for many physiological functions, are involved in processes including oxidative stress and inflammation.
