 Individuals entering US Army service are generally young and healthy, but many are overweight, which may impact cardiometabolic risk despite physical activity and fitness requirements. This analysis examines the association between Soldiers? BMI at accession and incident cardiometabolic risk factors (CRF) using longitudinal data from 731,014 Soldiers (17.0% female
  age: 21.6 [3.9] years
  BMI: 24.7 [3.8] kg/m<
 ) who were assessed at Army accession, 2001?2011. CRF were defined as incident diagnoses through 2011, by ICD-9 code, of metabolic syndrome, glucose/insulin disorder, hypertension, dyslipidemia, or overweight/obesity (in those not initially overweight/obese). Multivariable-adjusted proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) between BMI categories at accession and CRF. Initially underweight (BMI<
 18.5 kg/m<
 ) were 2.4% of Soldiers, 53.5% were normal weight (18.5-<
 25), 34.2% were overweight (25-<
 30), and 10.0% were obese (?30). Mean age range at CRF diagnosis was 24?29 years old, with generally low CRF incidence: 228 with metabolic syndrome, 3,880 with a glucose/insulin disorder, 26,373 with hypertension, and 13,404 with dyslipidemia. Of the Soldiers who were not overweight or obese at accession, 5,361 were eventually diagnosed as overweight or obese. Relative to Soldiers who were normal weight at accession, those who were overweight or obese, respectively, had significantly higher risk of developing each CRF after multivariable adjustment (HR [95% CI]: metabolic syndrome: 4.13 [2.87?5.94], 13.36 [9.00?19.83]
  glucose/insulin disorder: 1.39 [1.30?1.50], 2.76 [2.52?3.04]
  hypertension: 1.85 [1.80?1.90], 3.31 [3.20?3.42]
  dyslipidemia: 1.81 [1.75?1.89], 3.19 [3.04?3.35]). Risk of hypertension, dyslipidemia, and overweight/obesity in initially underweight Soldiers was 40%, 31%, and 79% lower, respectively, versus normal-weight Soldiers. BMI in early adulthood has important implications for cardiometabolic health, even within young, physically active populations.
