The aim of this study was to determine whether low levels of OCN would be associated with insulin resistance, obesity, and greater cardiovascular (CV) risk in young adults just emerging from adolescence. Undercarboxylated OCN and carboxylated OCN levels were measured on stored serum samples (total OCN = undercarboxylated OCN + carboxylated OCN) on 137 participants (67 males) at mean age 18.6 years (range 17\u201322 years). Insulin resistance was measured by hyperinsulinemic\u2014euglycemic clamp (M<jats:sub>lbm<\/jats:sub>). Multivariable regression analyses with ln(OCN) as the independent variable were adjusted for age, sex, ethnicity, and BMI as indicated. Total OCN was inversely related to BMI, waist circumference, systolic blood pressure (SBP), interleukin (IL)\u20106, and directly related to M<jats:sub>lbm<\/jats:sub>; only SBP remained significant (with M<jats:sub>lbm<\/jats:sub> <jats:italic>P<\/jats:italic> = 0.0560) after further adjustment for BMI. Carboxylated OCN was inversely related to BMI, waist circumference, SBP, low\u2010density lipoprotein cholesterol (LDL\u2010C), and directly related to adiponectin; SBP and adiponectin remained significant after further adjustment for BMI. There were no significant associations with undercarboxylated OCN. In summary, most associations with OCN were mediated via BMI. However, the significant associations of OCN with SBP, obesity, and adiponectin and borderline with M<jats:sub>lbm<\/jats:sub>, suggest a potential role for OCN in the development of insulin resistance and CV risk that becomes more apparent with aging into older adulthood.<\/jats:p>","DOI":"10.1038\/oby.2012.108","type":"journal-article","created":{"date-parts":[[2012,5,10]],"date-time":"2012-05-10T12:32:29Z","timestamp":1336653149000},"page":"2194-2201","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Association
