Table 3 Relationship between the RT tests with possible confounders (step 1) and the obesity indices (step 2)

From: Simple reaction time and obesity in children: whether there is a relationship?

  1. BMI body mass index, PA physical activity, RT clin clinical reaction time, RTA audio reaction time, RTV visual reaction time, SES socioeconomic status, WC waist circumference, WHtR waist to hip ratio
  2. Note: In the first step confounding variables (age, SES and PA) were entered, and in the second step obesity indices were entered, separately
