Prevalence of Presbyphonia in Older Adults With Dysphonia: A Systematic Review and Meta-Analysis.

PURPOSE: This study aims to investigate the prevalence of presbyphonia among older adults who report voice complaints. METHOD: We conducted a systematic search of five medical databases to identify studies that reported on presbyphonia as the cause of voice disorders in older adults. The pooled prevalence was calculated using random-effects models and presented as percentages with 95% confidence intervals (CI). The degree of heterogeneity among studies was assessed using I2 statistics. Subgroup analyses were performed to identify the sources of heterogeneity. RESULTS: Out of 764 abstracts from five libraries, 11 studies were included in this systematic review. The pooled prevalence of presbyphonia among older adults with voice disorders is 17.78% (95% CI [12.69, 23.51]). We conducted a subgroup analysis on studies that used laryngeal visualization to confirm the diagnosis for all patients and found that the prevalence of presbyphonia was lower in studies with unrestrictive inclusion criteria (12.84%, 95% CI [8.38, 18.08]) compared to studies with restricted inclusion criteria (22.59%, 95% CI [14.49, 31.88]). CONCLUSIONS: This study suggests that voice disorders in older adults have multiple causes, not predominantly presbyphonia. Overestimation of presbyphonia prevalence occurs if certain diagnoses are excluded at recruitment. This study emphasizes the importance of recognizing the diverse underlying etiologies of dysphonia in older adults; therefore, comprehensive examination and accurate diagnosis are crucial.

Prevalence of Voice Disorders in Older Adults: A Systematic Review and Meta-Analysis.

PURPOSE: Voice disorders significantly impair the ability to communicate effectively and reduce the quality of life in older adults; however, its prevalence has not been well established. The aim of our research was to investigate the prevalence and associated factors of voice disorders among the older population. METHOD: Five medical databases were systematically searched for studies that reported the prevalence of voice disorders in older adults. The overall prevalence was exhibited in proportions and 95% confidence intervals (CIs) utilizing random-effects models. Heterogeneity was measured using I 2 statistics. RESULTS: Of 930 articles screened, 13 fulfilled the eligibility criteria, including 10 studies in community-based settings and three in institutionalized settings. An overall prevalence of voice disorders in older adults was estimated to be 18.79% (95% CI [16.34, 21.37], I 2 = 96%). Subgroup analysis showed a prevalence of 33.03% (95% CI [26.85, 39.51], I 2 = 35%) in institutionalized older adults, which was significantly higher than that in the community-based older adults with 15.2% (95% CI [12.65, 17.92], I 2 = 92%). Some factors that influenced the reported prevalence were identified, including types of survey, the definition of voice disorders, sampling methods, and the mean age of the population among included studies. CONCLUSIONS: The prevalence of voice disorders in the older population depends on various factors but is relatively common in older adults. The findings of this study accentuate the necessity for researchers to standardize the protocol for reporting geriatric dysphonia as well as for older adults to express their voice-related problems so that they will receive appropriate diagnosis and treatment.

Transitions of self-management behaviors and frailty status among community-dwelling older adults: a national longitudinal population-based cohort study.

BACKGROUND: Frailty in older adults is a common geriatric syndrome that could be prevented; thus, coping strategies for the aging population are essential. Self-management behaviors may represent cost-effective strategies to prevent physical frailty in community-dwelling older adults. This study aimed to describe the changes in frailty status among community-dwelling older adults in Taiwan and investigate the association between transitions of self-management behaviors and frailty status over 4 years of follow-up (2007 to 2011). METHODS: Data were retrieved from the Taiwan Longitudinal Study of Aging (TLSA), years 2007 and 2011. In this prospective cohort study, 1283 community-dwelling older adults aged 65 years and older without cognitive impairment were recruited. Frailty was defined based on Fried's frailty phenotype. Self-management behaviors (maintaining body weight, quitting smoking or no smoking, drinking less or no drinking, exercising, keeping diet control, and maintaining a regular lifestyle) were assessed using a questionnaire. Multinomial logistic regression analyses were used to investigate the associations between changes in self-management behaviors and in frailty status. The age group was further stratified to examine the moderation effect in the relationship between changes in self-management behaviors and in frailty status among older adults. RESULTS: The prevalence of frailty was 8.7% at baseline and 14.9% after 4 years of follow-up, with 196 (15.3%) deaths. Overall, 514 (40.1%) participants maintained their frailty status, 424 (33.0%) worsened, and only 149 (11.6%) improved. Being aged ≥75 years old, having chronic diseases, and an absence of self-management behaviors were associated with frailty at baseline and after follow-up. Among individuals aged 65-74, compared to those who maintained no self-management behaviors, those who decreased the exercise behaviors (yes-to-no) had a higher risk of worsening (RRR = 2.518), while increasing (no-to-yes) and maintaining (yes-to-yes) frequent physical exercise were associated with a lower risk of worsening (RRR = 0.466 and 0.572, respectively) than stable frailty; those who maintained body weight (yes-to-yes) were associated with a lower risk of worsening (RRR = 0.327) than stable frailty after controlling for individual covariates and chronic diseases. Among individuals over 75 years old, compared to no exerciser, older old who decreased their physical exercise had a higher risk of frailty worsening (RRR = 3.255), and increasing frequent physical exercise (no-to-yes) was associated with an improvement in frailty status (RRR = 3.684). Age was a moderator between the effects of maintaining body weight on frailty worsening. There were no associations between the behavioral transitions of smoking, drinking, diet control, or regular lifestyle on the frailty status changes. CONCLUSIONS: Maintaining body weight and frequent physical exercise increased the ratio of frailty stability among individuals 65-74 years old. Increasing exercise behavior is the only factor to improve their frailty status among older adults aged 75 years and over. Older adults should be encouraged to perform adequate physical exercise and maintain a healthy body weight to maintain the frailty status in younger old aged 65-74 years, and especially perform more frequent exercise to improve frailty status in older old over 75 years.

Prevalence of Frailty among Community-Dwelling Older Adults in Asian Countries: A Systematic Review and Meta-Analysis.

This study aimed to synthesize frailty prevalence among community-dwelling older adults in Asia and identify factors influencing prevalence estimates. Five electronic databases were searched by 29 April 2022, including representative samples of community-dwelling adults who were aged 60 years and older and lived in Asia. Cross-sectional or national longitudinal population-based cohort studies completed with validated instruments were selected. Twenty-one studies with 52,283 participants were included. The pooled prevalence rate of frailty was 20.5% (95% CI = 15.5% to 26.0%). The estimated frailty prevalence was 14.6% (95% CI = 10.9% to 18.8%) while assessed by the Fried frailty phenotype, 28.0% (95% CI = 21.3% to 35.3%) by the Cumulative Frailty Index, 36.4% (95% CI = 33.6% to 39.3%) by the Study of Osteoporotic Fractures (SOF) index, and 46.3% (95% CI = 40.1% to 52.4%) by the Clinical Frailty Scale (p < 0.01). Subgroup analysis in studies using the Fried's phenotype tool found that frailty prevalence was increased with older age (p = 0.01) and was higher in those who were single (21.5%) than in married participants (9.0%) (p = 0.02). The study results supported a better understanding of frailty prevalence in different geographical distributions and provide references for health policy decision-making regarding preventing frailty progression in older adults.
