  1. Coefficients represent the change in one mmHg of systolic blood pressure for an extra 1 h spent per day in TV viewing or videogames or computer use or total screen-time or sedentary time. The model was adjusted for age, sex (in the analysis of the total sample), governorate, maternal education and moderate to vigorous physical activity (MVPA). MVPA estimates were derived from the same model, i.e. they were adjusted for age, sex, governorate, maternal education, and sedentary time. Total screen-time = TV viewing + Videogames + Computer use
  2. OR odds ratio, CI confidence intervals
