Key result
Reductions in BMI z score after a 1-year lifestyle intervention were significantly associated with reductions in 24-hour ambulatory systolic blood pressure (6.5 mmHg per 1 BMI z score reduction, P<0.05).

Does weight reduction through lifestyle intervention improve ambulatory blood pressure in severely obese children and adolescents?
Mean Difference: -6.5
p-value: p=<0.05
In severely obese children and adolescents, weight reduction through lifestyle intervention significantly improves ambulatory blood pressure, highlighting the importance of 24-hour ABP monitoring over clinic BP in this population.
Hvidt et al. (2014) conducted a cohort in Severe obesity (n=61). Reduction in BMI z score (following lifestyle intervention) vs. Baseline was evaluated on Change in 24-hour systolic blood pressure (6.5 mmHg reduction per 1 unit reduction in BMI z score, p=<0.05). Reductions in BMI z score after a 1-year lifestyle intervention were significantly associated with reductions in 24-hour ambulatory systolic blood pressure (6.5 mmHg per 1 BMI z score reduction, P<0.05).
