Trajectories of circulating BCAA concentrations from years 2\u201330 (for prevalent DM) or years 2\u201320 (for incident DM) were determined by latent class modeling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      Among 3,081 apparently healthy young adults, trajectory analysis from years 2\u201330 revealed 3 distinct BCAA trajectory groups: low-stable (\n                      <jats:italic>n<\/jats:italic>\n                      = 1,427), moderate-stable (\n                      <jats:italic>n<\/jats:italic>\n                      = 1,384), and high-increasing (\n                      <jats:italic>n<\/jats:italic>\n                      = 270) groups. Male sex, higher body mass index, and higher atherogenic lipid fractions were more common in the moderate-stable and high-increasing groups. Higher risk of prevalent DM was associated with the moderate-stable (OR = 2.59, 95% CI: 1.90\u20133.55) and high-increasing (OR = 6.03, 95% CI: 3.86\u20139.43) BCAA trajectory groups in adjusted models. A separate trajectory group analysis from years 2\u201320 for incident DM after year 20 showed that moderate-stable and high-increasing trajectory groups were also significantly associated with higher risk of incident DM, after adjustment for clinical variables and glucose levels.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>BCAA levels track over a 28-year span in most young adults, but serial clinical metabolomic measurements identify subpopulations with rising levels associated with high risk of DM in later life.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>FUNDING<\/jats:title>\n                    <jats:p>This research was supported by the NIH, under grants R01 HL146844 (JTW) and T32 HL069771 (MRC).
