Slower walking, weakness, and repeated falls may signal sarcopenia. Taipei Veterans General Hospital Taitung Branch advises measuring calf circumference first. Those scoring 4 or higher on the Sarcopenia Risk Assessment Questionnaire (SARC-F) should seek further medical assessment.

Psychiatrist Liao Ying-chih said sarcopenia involves declines in skeletal muscle mass, strength, and physical performance. It can limit daily movement and raise the risks of falls, hospitalization, and disability, affecting older adults' quality of life.

Risk can be screened at home using calf circumference and the SARC-F questionnaire. Medical assessment is recommended when calf circumference is below 34 cm for men or 33 cm for women, or when the questionnaire score reaches 4. Doctors may further examine grip strength, physical performance, and muscle mass.

Walking alone may not be enough for prevention. When physically able, older adults can add resistance exercises using dumbbells or resistance bands, consume adequate protein and calories, and receive moderate sunlight. Those losing weight should also watch for muscle loss.

Taiwan became a super-aged society in December 2025. Families noticing slower movement or repeated falls can arrange an early health assessment. A balanced diet, regular exercise, moderate sunlight, and periodic checkups can help older adults maintain mobility.
