  • Data are regression coefficents (95% CI).

  • *

    * Each model shows the mean difference in glycemic measures for increasing categories of television (TV) watching relative to the reference (Ref.) category (<1 h). All models are adjusted for age, height, waist, education, smoking, dietary covariates (total energy, total fat, total saturated fat, total carbohydrate, total sugars, fiber, and alcohol), and physical activity time.

  • Fasting serum insulin and HOMA variables were logarithmically transformed before inclusion in the model. Coefficients and 95% CIs reflect transformed values.
