What are some fall risk factors? A comprehensive guide to prevention

According to the Centers for Disease Control and Prevention (CDC), more than one in four older people fall each year, but fewer than half report it to their doctor. Knowing what are some fall risk factors is the first step toward creating a safer environment and preventing a potentially life-altering event.

Quick Summary

Fall risk factors range from intrinsic issues like muscle weakness and chronic health conditions to extrinsic environmental hazards such as poor lighting and clutter, underscoring the need for a comprehensive prevention strategy.

Key Points

• Intrinsic vs. Extrinsic: Fall risks are caused by a combination of internal health factors (intrinsic) and external environmental hazards (extrinsic).

• Muscle Weakness: Age-related muscle loss, or sarcopenia, is a major intrinsic factor that can be counteracted with exercise.

• Medication Management: Certain medications can cause dizziness or confusion; a regular review with a doctor can help manage side effects.

• Home Safety Audit: Simple home modifications like removing rugs and improving lighting can eliminate many extrinsic hazards.

• Regular Health Checks: Addressing vision and hearing impairments, along with managing chronic conditions like arthritis and diabetes, is vital for prevention.

• Fear of Falling: The fear of falling can reduce activity, leading to weaker muscles and increased risk, creating a vicious cycle that needs to be addressed.

Intrinsic Factors: Internal Causes of Falls

Intrinsic factors are those related to an individual's physical and mental state. As people age, natural changes can increase susceptibility to falls, as can pre-existing medical conditions and medications.

Physical and Physiological Changes

• Muscle Weakness and Sarcopenia: The age-related loss of muscle mass, strength, and function (sarcopenia) significantly impacts stability and balance. This reduces an individual's ability to recover quickly from a trip or slip. Regular exercise, especially strength training, is crucial to counteract this decline.
• Balance and Gait Issues: Impairments in balance and an unsteady gait are major contributors to falls. Conditions affecting the inner ear (vestibular system), nerve endings, and overall coordination can diminish the body's ability to maintain equilibrium, especially on uneven surfaces.
• Decreased Reflexes: Slower reaction times as a person ages mean they may not be able to correct their posture in time to prevent a fall after losing balance.
• Postural Hypotension: A sudden and significant drop in blood pressure when standing up from a sitting or lying position can cause dizziness, lightheadedness, or fainting, directly leading to a fall.

Medical Conditions

Numerous chronic health issues can increase fall risk. Managing these conditions effectively with a healthcare provider is a critical part of a fall prevention plan.

• Neurological Diseases: Conditions like Parkinson's disease, stroke, and dementia can affect mobility, coordination, and judgment, increasing the risk of falling. Cognitive impairment can also affect spatial awareness and the ability to recognize hazards.
• Cardiovascular Disease and Diabetes: Heart conditions and diabetes can affect balance and lead to complications such as neuropathy, which causes numbness or pain in the feet and legs.
• Arthritis and Foot Problems: Painful and stiff joints from arthritis can make walking difficult. Painful foot conditions, poor-fitting footwear, and foot deformities also affect balance and gait.
• Incontinence: The need to rush to the bathroom can lead to hurried and unsafe movements, increasing the likelihood of an accident.

Sensory Impairment

Clear vision and hearing are essential for safely navigating the environment. Impairments can lead to misjudging distances or not noticing hazards.

• Vision Problems: Age-related vision changes, such as reduced depth perception, poor contrast sensitivity, and conditions like cataracts or glaucoma, can obscure tripping hazards. The use of bifocal or multifocal glasses has also been linked to an increased risk of falls, especially on stairs.
• Hearing Loss: Problems with hearing can also affect balance, as the inner ear is critical for both hearing and maintaining equilibrium.

Medications (Polypharmacy)

Taking multiple medications (polypharmacy) significantly increases the risk of side effects that can cause falls. This includes both prescription and over-the-counter drugs.

• Sedatives and Antidepressants: Many drugs prescribed for sleep or mood can cause drowsiness, dizziness, and confusion.
• Blood Pressure Medications: Some antihypertensives can cause orthostatic hypotension, as mentioned earlier.

Extrinsic Factors: Environmental and External Hazards

Often more modifiable than intrinsic factors, environmental hazards can be addressed with simple, effective changes to the home and lifestyle.

Home Environmental Hazards

• Uneven Surfaces and Clutter: Throw rugs, electrical cords, and clutter are among the most common tripping hazards. Uneven flooring or broken steps also present a significant risk.
• Poor Lighting: Inadequate lighting, especially in stairways, hallways, and bathrooms, makes it difficult to see potential dangers. Glare from shiny floors can also be disorienting.
• Lack of Safety Devices: The absence of grab bars in the bathroom, handrails on both sides of staircases, and non-slip mats in wet areas creates unsafe conditions.

Lifestyle and Behavioral Factors

• Inappropriate Footwear: Shoes that are poorly fitting, lack support, or have slippery soles (like slippers or socks without grip) can increase the risk of slipping.
• Sedentary Lifestyle: A lack of physical activity leads to reduced strength and poor balance, which increases the likelihood of a fall. Regular movement helps maintain muscle mass and joint flexibility.
• Rushing and Inattention: Hurrying to answer the phone or get to the bathroom increases the chance of a misstep or accident. Mindful movement is an important prevention strategy.

Intrinsic vs. Extrinsic Fall Risk Factors

Feature	Intrinsic Factors	Extrinsic Factors
Description	Relate to an individual's internal physical or mental state.	Relate to external environmental and situational conditions.
Examples	Muscle weakness, chronic diseases, poor vision, balance problems, medication side effects.	Home hazards (clutter, rugs), poor lighting, slippery floors, improper footwear.
Modifiability	Often require medical intervention, lifestyle changes (exercise, diet), and ongoing management.	Generally can be addressed with practical home modifications and behavioral adjustments.
Management	Consult with healthcare providers for regular check-ups, medication reviews, and physical therapy.	Perform a home safety audit, install grab bars and handrails, wear proper footwear, and declutter living spaces.

Proactive Steps for Fall Prevention

1. Start an Exercise Program: Engage in strength and balance training exercises, such as Tai Chi, which is proven to reduce fall risk.
2. Review Medications Annually: Talk to your doctor or pharmacist about any medications that might cause dizziness or unsteadiness. Many drugs can be adjusted or changed.
3. Address Vision and Hearing: Get regular eye and hearing exams. Wear prescription glasses as advised and ensure hearing aids fit properly.
4. Make Home Modifications: Conduct a home safety check. Install grab bars, add non-slip mats, improve lighting, and remove tripping hazards like loose rugs.
5. Choose Proper Footwear: Wear sturdy, rubber-soled shoes with good support. Avoid going barefoot or wearing floppy slippers.
6. Stay Hydrated and Eat Well: Proper nutrition, including sufficient Vitamin D and calcium, supports bone and muscle health. Hydration helps prevent dizziness.
7. Address Fear of Falling: A fear of falling can lead to reduced activity, which paradoxically increases the risk of future falls. Seek professional guidance if this fear is impacting daily life.
