From 2021 to 2023, we performed an in\u2010person examination on 1421 offspring, including obtaining questionnaire responses addressing health status and health behaviors, and performance of anthropometry, blood pressure measurement, phlebotomy, and carotid ultrasonography using standardized protocols. An additional 620 offspring answered questionnaires electronically. Cardiovascular health status was quantified using the Life's Essential 8 score (0\u2013100; higher is better cardiovascular health). Measurement of carotid intima\u2010media thickness, grayscale lucency, and carotid distensibility was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      Among 1975 nonpregnant participants, mean age was 23.2\u00b10.8\u2009years, 55% identified as female, 19.5% White, 49.1% Black, 26.7% Hispanic, and 4.7% as Asian or multiple race\/ethnicity.
