SMARTPHONE (CELL PHONE) USE AND ITS RELATIONSHIP WITH SARCOPENIA IN ADULTS: INTEGRATIVE REVIEW

Abstract

Sarcopenia is characterized by the involuntary and progressive loss of muscle mass and function, being a common condition among the elderly population. However, prolonged use of electronic devices, such as smartphones, has been associated with postural changes, musculoskeletal pain, and increased sedentary behavior, factors that may negatively impact muscle health over time. This study aimed to analyze, through an integrative literature review, the relationship between prolonged smartphone use and the risk of developing sarcopenia in adults, considering musculoskeletal, postural, and behavioral aspects, as well as highlighting the role of physiotherapy in the prevention and management of these dysfunctions. The bibliographic search was conducted in the LILACS, SciELO, Google Scholar databases, and electronic journals, identifying 25 articles published between 2015 and 2024. Of these, 10 met the inclusion criteria, and 6 were selected for their greater relevance. The descriptors used were “sarcopenia,” “smartphone,” “sedentary lifestyle,” and “adults.”The results showed that daily smartphone use for more than five hours is associated with an average 34% reduction in physical activity and a 49.4% increase in musculoskeletal complaints. Although there is no direct evidence linking prolonged smartphone use to sarcopenia, the sedentary behavior and associated musculoskeletal changes may compromise muscle function. Physiotherapy acts preventively and therapeutically through postural education, exercises, and active breaks, minimizing these impacts.
