From: Do teachers have more health problems? Results from a French cross-sectional survey

Age Mean values
  Males Females
  Teachers (N = 1,496) Controls (N = 875) Teachers (N = 2,183) Controls (N = 942)
20 – 39 years 23.7 23.9 21.7 22.6
40 – 49 years 24.8 25.1 22.5 22.9
≥ 50 years 25.0 25.8 23.0 23.3
Total 24.5 25.0 22.4 22.9
  1. BMI = Body Mass Index. Mean value = observed mean age of the subjects in each category for each group. For both males and females, a linear regression analysis was applied to test the difference in mean values between the two groups, while controlling for age and educational level. No significant difference was found.
