Sarcopenia and severe sarcopenia were defined using 2019 revised European Working Group on Sarcopenia in Older People criteria. Prevalence was standardised by age and gender within each country. We examined associations between sarcopenia and individual-level sociodemographic and health characteristics, and country-level socioeconomic indicators.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Sarcopenia prevalence ranged from 2.1% to 17.4% across 36 countries, with 16 countries above 5.0% and three above 10.0%. Approximately 92.7 million of 1.07 billion adults \u226550 in these countries were projected to have sarcopenia. At the individual-level, higher risk was associated with older age, gender (men), lower education, being unmarried or not partnered, non-full-time employment, lower household wealth, current smoking, non-recent drinking, physical inactivity and\u2009\u22652 chronic diseases (e.g. men: RR\u2009=\u20091.47; 95% CI: 1.32, 1.64). At the country-level, higher gross domestic product (GDP) per capita, higher Gender Development Index and lower Labor Force Participation Rate were associated with lower sarcopenia risk (e.g. GDP per capita: RR\u2009=\u20090.42; 95% CI: 0.30, 0.60).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Sarcopenia varies widely across countries and is more common in middle-income than high-income settings, pointing to a pattern shaped by both personal and contextual conditions.
