Aims: To examine how community-dwelling older adults in Southern Thailand conceptualise possible sarcopenia and how these meanings shape everyday health behaviours relevant to prevention.
Methods: A naturalistic inquiry approach was adopted. Interviews explored perceived bodily changes, interpretations of strength and functional ability, and routine practices related to physical activity, nutrition, healthcare utilisation, and social support. Data were analysed using thematic analysis.
Results: Findings indicated a trajectory from recognising bodily slowing to adapting daily routines to preserve independence.Eight themes characterised participants’ accounts: (1) Making sense of a slowing body; (2) normalizing decline while still fighting it; (3) redefining what ‘being healthy’ means in later life; (4) walking as the measure of a livable body; (5) Eating to feel strong: practical nutrition for everyday function; (6) muscle health as an invisible issue in healthcare; (7) Self-constructed care within informal support networks; and (8) Protecting independence and not being a burden.
Conclusions: Big data can stratify risk, but “deeper wisdom” explains how prevention is sustained in everyday life. Older adults primarily framed possible sarcopenia prevention in terms of preserving independence and dignity rather than biomedical optimisation.
