Key result
Lower prevalence of respiratory sinus arrhythmia among children with overweight and obesity is a result of higher resting heart rate, which inversely correlates with sinus arrhythmia indices.
Why the study?
The implications of anthropometry in school-aged children on the degree of respiratory sinus arrhythmia observed in clinical settings were unclear.
Do anthropometric factors determine the degree of respiratory sinus arrhythmia in healthy school-aged children?
Cohort (n=626)
No
Do anthropometric factors determine the degree of respiratory sinus arrhythmia in healthy school-aged children?
Lower prevalence of respiratory sinus arrhythmia in overweight and obese children is driven by their higher resting heart rate rather than direct anthropometric effects.
Lower BMI and weight linked to higher RSA prevalence in children; leaves open whether anthropometry influences pediatric autonomic function.
BACKGROUND: The study was conducted to investigate the implications of anthropometry in school-aged children on the degree of respiratory sinus arrhythmia observed in clinical settings. METHODS: In a cohort study, 626 healthy children (52% male) aged 10.8 ± 0.5 years attending primary school in a single town underwent a 12-lead electrocardiogram coupled with measurements of height, weight and blood pressure. Indices of respiratory sinus arrhythmia (pvRSA, RMSSD, RMSSDc) were derived from semi-automatic measurements of RR intervals. Height, weight, BMI, blood pressure as well as waist and hip circumferences were compared between subjects with rhythmic heart rate and respiratory sinus arrhythmia, and correlations between indices of sinus arrhythmia and anthropometry were investigated. RESULTS: = 0.004) blood pressure. There were important inverse correlations of heart rate and indices of sinus arrhythmia (r = -0.52 for pvRSA and r = -0.58 for RMSSD), but not the anthropometry. CONCLUSION: Lower prevalence of respiratory sinus arrhythmia among children with overweight and obesity is a result of higher resting heart rate observed in this population.

Lubocka et al. (2022) conducted a cohort in Healthy children (n=626). Anthropometry (overweight and obesity) was evaluated on Indices of respiratory sinus arrhythmia (pvRSA, RMSSD, RMSSDc). Lower prevalence of respiratory sinus arrhythmia among children with overweight and obesity is a result of higher resting heart rate, which inversely correlates with sinus arrhythmia indices.
