Waist circumference >102 cm for men and >88 cm for women.
Adjusted for age, ethnicity/clinic, baseline BMI, family history of diabetes, smoking status, glucose tolerance status, education, and energy intake (by residual method).
Decrease: change in waist ≤−2 cm; stable: change in waist ±2 cm; increase: change in waist ≥2 cm.
Adjusted for age, ethnicity/clinic, baseline BMI, baseline waist circumference, family history of diabetes, smoking status, glucose tolerance status, education, and energy intake (by residual method).
Tertile-specific ORs were not estimated if the reference category comprised <10 subjects.
