Key result
A weight reduction program in children with obesity significantly increased general heart rate variability (P<0.001) and parasympathetic regulation (P<0.01), but did not alter stress reactivity.

Does an inpatient weight reduction program improve baseline and stress-induced heart rate variability in children with obesity?
p-value: p=<0.001
An inpatient weight reduction program in children with obesity shifts baseline autonomic activity toward parasympathetic dominance but does not alter autonomic reactivity during stress conditions.
Mazurak et al. (2015) conducted an observational in Obesity (n=87). Weight reduction program vs. Baseline values and normal-weight peers was evaluated on Heart rate variability (HRV) at baseline, during mental stress, and recovery (p=<0.001). A weight reduction program in children with obesity significantly increased general heart rate variability (P<0.001) and parasympathetic regulation (P<0.01), but did not alter stress reactivity.
