Risk factors for frailty in older adults

Area of Science:

• Gerontology
• Public Health
• Internal Medicine

Background:

• Frailty is a growing concern in aging populations worldwide.
• Understanding frailty's risk factors is crucial for developing effective prevention strategies.

Purpose of the Study:

• To identify and synthesize the key risk factors associated with frailty in the elderly population.
• To provide evidence for early interventions aimed at preventing frailty and its associated complications.

Main Methods:

• A comprehensive literature search was conducted across PubMed, EMBASE, and Cochrane Library.
• Studies were identified using keywords such as "frailty," "weak," "risk factors," and "predictive factors."
• Elderly individuals (≥65 years) were categorized into frailty and robust control groups for comparative analysis of characteristics, lifestyles, and comorbidities.

Main Results:

• Baseline factors associated with increased frailty risk include advanced age, lower body weight, female sex, living alone, physical inactivity, polypharmacy, higher education, smoking, alcohol consumption, malnutrition, and low vitamin D levels.
• Concomitant diseases significantly increasing frailty risk encompass diabetes, hearing impairment, cognitive dysfunction, poor sleep quality, history of falls, chronic pain, and depression.
• Both individual characteristics and comorbidities play a substantial role in the development of frailty.

Conclusions:

• Frailty is influenced by a complex interplay of demographic characteristics, lifestyle choices, and existing health conditions.
• Targeting modifiable risk factors identified in this review can inform clinical practice and public health initiatives for frailty prevention.
• Further consideration of these influencing factors is essential for comprehensive geriatric care and management.
