This study aimed to identify DASH score trajectories from early to middle adulthood and assess their association with CAC progression in middle age, exploring the potential mediating factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">We conducted a prospective analysis of 2238 Black and White adults who were aged 18 to 30\u2009years at CARDIA (Coronary Artery Risk Development in Young Adults) baseline and were followed from study year 20 to year 25. DASH score trajectories from early to middle adulthood were determined using latent class analysis. The primary end point was CAC progression, a validated measure of plaque progression, defined as a &gt;2.5 square root\u00a0increase in CAC score between years 20 and 25.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      Two distinct DASH score trajectories were identified: the low\u2010increasing and high\u2010decreasing trajectories. In the fully adjusted model, participants in the high\u2010decreasing trajectory had a 21% lower risk of CAC progression compared with those in the low\u2010increasing trajectory (hazard ratio, 0.79 [95% CI, 0.65\u20130.98];\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      =0.028).

Maintaining high adherence to the DASH diet from early to middle adulthood is associated with reduced CAC progression in middle age, partially mediated by cardiometabolic risk factors. These findings support the importance of long\u2010term adherence to a healthy dietary pattern for cardiovascular disease primary prevention.<\/jats:p>\n                    <jats:p xml:lang=\"en\">\n
