Note. Data are expressed as β value and standard errors (SE). Model 1: adjusted for age and service specialty; Model 2: adjusted for age, service specialty, and body mass index. Model 3: adjusted for age, service specialty, educational level, body mass index, systolic blood pressure, current smoking, alcohol intake, hemoglobin levels, and exercise frequency.
