Nearly 1 in 5 community-dwelling older adults may have sarcopenia.
A 2025 systematic review and meta-analysis examined 52 studies involving more than 70,000 older adults. Researchers estimated that sarcopenia affected 18.8% of community-dwelling older adults. The study also found links between sarcopenia and older age, malnutrition, and low physical activity.
What Is Sarcopenia?
The National Institute on Aging (NIA) defines Sarcopenia as a decline in muscle mass, strength, and function. It is often associated with aging. It can cause weakness and fatigue. It can also make everyday activities such as standing, walking, and climbing stairs more difficult.
For caregivers, this raises an important question: How can we recognize possible signs of sarcopenia early?
One simple screening tool is the SARC-F.
What Is SARC-F?
SARC-F is a five-question screening tool. It focuses on common problems that can occur with muscle weakness.
The questions cover:
- Strength: Difficulty lifting or carrying 10 pounds
- Assistance with walking: Difficulty walking across a room
- Rise from a chair: Difficulty getting up from a chair or bed
- Climb stairs: Difficulty climbing 10 stairs
- Falls: Number of falls during the past year
Each area receives a score from 0 to 2. The total score ranges from 0 to 10.
A score of 4 or higher suggests a higher risk of sarcopenia.
It does not confirm a diagnosis. A healthcare professional can determine whether additional testing is needed.
Try the SARC-F Screening
Caregiverlist® has created an online SARC-F screening based on the five areas used in the questionnaire. It takes under a minute to complete.
SARC-F Questionnaire
Five questions on strength, walking, rising, stairs, and falls. Takes under a minute. Answer based on your typical ability over the past few weeks.
Score by component
This tool is for informational and educational purposes only. If you’re concerned about strength, mobility, or falls, please discuss these results with a doctor or physical therapist.
SARC-F is a screening tool. It is not a diagnostic test.
Use the results as a starting point for a conversation with a healthcare professional.
At Caregiverlist®, we believe early action can support healthier aging and help older adults maintain strength and independence.

What does a SARC-F score of 4 or higher mean?
A score of 4 or higher suggests a higher risk of sarcopenia. It does not confirm that a person has sarcopenia.
Can SARC-F diagnose sarcopenia?
No. SARC-F is a screening tool. A healthcare professional must complete further assessment to diagnose sarcopenia.
Who can take the SARC-F screening?
Older adults can complete the screening based on their current abilities. Caregivers can also help a person understand and answer the questions.
How long does the SARC-F screening take?
The screening has only five questions. It takes just a few minutes to complete.
What should I do if the score is 4 or higher?
Share the result with a healthcare professional. They can determine whether the person needs further assessment.
Why should caregivers pay attention to muscle strength?
Changes in strength can affect mobility and daily activities. Early recognition can help caregivers bring concerns to the attention of the healthcare team.
