Although obesity is a major modifiable risk factor for ED, the longitudinal impact of body mass index (BMI) trajectories remains poorly understood, particularly in populations outside North America and Europe.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aim<\/jats:title>\n                    <jats:p>We aimed to examine the longitudinal association between BMI trajectory patterns and erectile dysfunction among Brazilian men.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This longitudinal cohort study included 924 Brazilian men aged \u226540\u00a0years with ED at baseline who underwent routine health evaluations between 2008 and 2022. BMI, ED (assessed with the IIEF-5), and demographic, clinical, and lifestyle factors were measured at baseline and follow-up visits (300\u2013800\u00a0days apart). Participants were categorized into four BMI trajectories: remained healthy, became healthy, became obese, or remained obese. Associations with ED were analyzed using hierarchical logistic regression adjusted for demographic, clinical, and behavioral covariates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Outcomes<\/jats:title>\n                    <jats:p>In this longitudinal cohort of Brazilian men aged \u226540\u00a0years, unfavorable BMI trajectories\u2014particularly becoming or remaining obese\u2014were independently associated with greater odds of erectile dysfunction.
