title: Physical Activity-Related Obesity Risk Classification Model and All-Cause Mortality.
abstract: This study evaluated a physical activity-related obesity model on mortality.
  
  
  
  Data from the 1999-2006 NHANES were used (N = 16,077), with follow-up through 2011. Physical activity (PA) was subjectively assessed, with body mass index (BMI) and waist circumference (WC) objectively measured. From these, 12 mutually exclusive groups (G) were evaluated, including: G1: Normal BMI, Normal WC and Active; G2: Normal BMI, Normal WC and Inactive; G3: Normal BMI, High WC and Active; G4: Normal BMI, High WC and Inactive; G5: Overweight BMI, Normal WC and Active; G6: Overweight BMI, Normal WC and Inactive; G7: Overweight BMI, High WC and Active; G8: Overweight BMI, High WC and Inactive; G9: Obese BMI, Normal WC and Active; G10: Obese BMI, Normal WC and Inactive; G11: Obese BMI, High WC and Active; and G12: Obese BMI, High WC and Inactive.
  
  
  
  Compared with G2, the following had a reduced mortality risk: G1, G3, G5, G6, G7, G8, G9, and G11. Compared with G12, the following had a reduced mortality risk: G1, G3, G5, G7, G9, and G11. In each respective group for BMI and WC, the active group had a reduced mortality risk.
  
  
  
  Across all BMI and WC combinations, PA improved mortality risk identification.
