Objectives:
To determine the prevalence of fear of falling (FOF) and fear-related activity restriction (FAR) and their association with frailty, sarcopenia, gait speed and grip strength, cognitive impairment, depression, social isolation, self-perceived health, and vision.
Design:
Observational cross-sectional study.
Setting:
Community.
Participants:
A total of 493 community-dwelling older adults, 60 years and older.
Measures:
FOF and FAR were assessed using validated single closed-ended questions. Questionnaire was administered to evaluate frailty (FRAIL scale - Fatigue, Resistance, Aerobic, Illness, and Loss of Weight), sarcopenia (SARC-F - lifting and carrying 10 pounds, walking across a room, transferring from bed/chair, climbing a flight of 10 stairs, and frequency of falls in the past 1 year), social isolation (six-item Lubben Social Network Scale), depression (Even Briefer Assessment Scale), cognition (Chinese Mini-Mental State Examination), and perceived general health and pain (The EuroQol-5 Dimension (EQ-5D)and EQ visual analogue scale (EQ VAS)) . Binary logistic regression was performed to determine the influence of sociodemographic, medical, functional, and cognitive variables on FOF with/without FAR.
Results:
Prevalence of FOF was 69.2%, and among them, 38.4% had FAR. Prevalence of FOF with or without FAR in those with sarcopenia was 93.3% and in prefrail/frail was 76.6%. FOF was significantly associated with prefrail/frail (odds ratio (OR) = 2.17; 95% confidence interval (CI) = 1.26-3.73), depression (OR = 4.90; 95% CI = 1.06-22.67), number of medications (OR = 1.28; 95% CI = 1.03-1.59), and female sex (OR = 3.54; 95% CI = 1.82-6.90). FOF + FAR was associated with depression (OR = 5.17; 95% CI = 1.84-14.54) and sarcopenia (OR = 8.13; 95% CI = 1.52-43.41).
Conclusion:
FOF with/without FAR is highly prevalent among community-dwelling older adults, especially in those with sarcopenia, prefrailty, and frailty, with significant negative impact on function, quality of life, social network, and mental health. Further research is needed to investigate the value of population-level screening, causal relationship, and efficacy of comprehensive intervention strategies.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
