“…However, while larger BMI was not associated with HRV, larger waist circumference was related to reduced VLF, which is partly consistent with past pediatric findings of greater obesity linked to reduced HRV [16,22,33].…”

Abstractand heart rate, are presented. Greater heart rate (β avg = −0.60, ), pubertal maturation (β avg = −0.11, ), later ECG recording times (β avg = −0.19, ), and higher diastolic blood pressure (β avg = −0.11, ) were significantly associated with reduced HRV in 10-year-old children. The normative HRV values permit clinicians to monitor, describe, and establish pediatric nosologies in primary care and research settings, which may improve treatment of diseases associated with HRV in children. By better understanding existing values, the practical applicability of HRV among clinicians will be enhanced. Lastly, developmental (e.g., puberty) and procedural (e.g., recording time) factors were identified that will improve recording procedures and interpretation of results.

“…Data that were analyzed by adjustments for confounders (specifically age and gender) were compared to those obtained in non-obese children and adolescents. The results expand previous information collected on this topic [3][4][5][6], by showing that the circadian pattern of parasympathetic and sympathetic control of the heart rate signal is altered in these young groups of obese. They also provide evidence that the alterations in vagal modulation of sinus node activity are manifest in both genders, independently of the subject's age and over the whole 24-h period.…”

Objective: Dysregulation of the autonomic nervous system is thought to be involved in craniopharyngioma-related hypothalamic obesity (CRHO). Increased parasympathetic activity and decreased sympathetic activity have been suggested. We aimed to study autonomic activity using heart rate variability (HRV) and biochemical measures in youth with CRHO compared with controls and to explore relationships between obesity and autonomic indices. Design: A cross-sectional study of 16 youth with CRHO and 16 controls matched for sex, age, and BMI. Methods: Anthropometrics, fasting blood-work, resting energy expenditure (REE), 24-h HRV, and 24-h urine catecholamines were assessed. Quality of life, sleepiness, and autonomic symptoms were evaluated. Power spectral analysis of the HRV was performed. Results: HRV power spectral analysis parameters of both parasympathetic activity (mean high frequency (HF (ms 2 )) 611G504 vs 459G336, PZ0.325) and sympathetic activity (median low frequency/HF 1.62 (1.37, 2.41) vs 1.89 (1.44, 2.99), PZ0.650) did not differ between the groups. Parasympathetic activity negatively correlated with central adiposity in both groups (rZK0.53, PZ0.034 and rZK0.54, PZ0.029) and sympathetic activity positively correlated with central adiposity in CRHO (rZ0.51, PZ0.043). Youth with CRHO had significantly lower REE; lower health and activity scores in the quality of life questionnaires, and higher sleepiness scores. Conclusions: Autonomic activity was similar in CRHO and control subjects. The degree of central adiposity correlated negatively with parasympathetic activity and positively with sympathetic activity in children with CRHO. These results provide a new perspective regarding autonomic balance in this unique patient population.
