Figure 1.

Box plot of casual blood pressure (BP) measurement and ambulatory monitoring of 24‐hour, daytime, and nighttime systolic BP (panel A) and diastolic BP (panel B) in obese (n=85, shaded boxes) and nonobese (n=88, filled boxes) children and adolescents. Casual systolic and diastolic BP were significantly higher in obese than in nonobese subjects (p<0.01 and p<0.05, respectively). Systolic BP over 24 hours was higher in obese than in nonobese children (p<0.01), and the magnitude of the differences was similar during the daytime (p<0.01) and nighttime periods (p<0.05). In contrast, diastolic BP did not significantly differ during the nighttime period, and only small differences were observed during the day (p<0.05).
