Answer

One study suggests that a lack of adequate sleep time in young children is associated with increased BMI; this observation is independent of other confounding variables (eg, physical activity). [6]

Furthermore, data indicate that over a 5-year period an increase in BMI among overweight children 6 to 11 years of age is associated with increases in both systolic and diastolic blood pressure, as well as with a decrease in sleep time. [7]
