Healthy ageing, as defined by the World Health Organization, emphasizes maintaining functional ability and well-being rather than the absence of disease. Physical activity is a key modifiable determinant of healthy ageing; however, evidence remains limited among older adults with chronic conditions and functional vulnerability. Therefore, this study aimed to examine the association between physical activity and healthy ageing among older adults with chronic conditions and\/or functional vulnerability in Iran.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This descriptive\u2013analytical cross-sectional study was conducted between August and October 2025 among older adults aged\u2009\u2265\u200960 years attending a public hospital and affiliated outpatient\/rehabilitation clinics in Qazvin Province, Iran. Participants were selected using simple random sampling. Eligibility was based on age, ability to communicate, informed consent, and evidence of chronic disease and\/or functional vulnerability identified through clinical history, participant report, and screening at recruitment. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). Healthy ageing was measured using the Healthy Ageing Questionnaire (HAQ) Index, and perspectives on healthy ageing were assessed using the Healthy Aging Perspectives Questionnaire (HAPQ). Associations were examined using correlation analyses, group comparisons, and multivariable linear regression models adjusting for sociodemographic and health-related covariates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 190 participants (mean age 68.0\u2009\u00b1\u20097.3 years; 57.4% women), 74.4% had low physical activity. Total physical activity was positively correlated with healthy ageing (HAQ total score: \u03c1\u2009=\u20090.42,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) and healthy ageing perspectives (HAPQ total score: \u03c1\u2009=\u20090.28,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001). In adjusted linear regression models, each 100 MET-min\/week increase in physical activity was associated with a 0.85-point higher HAQ score (95% CI 0.35\u20131.35;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.001) and a 0.018-point higher HAPQ score (95% CI 0.006\u20130.030;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.003).
