Why the study?

Does age affect beat-to-beat blood pressure and heart rate responses to active standing in children?

Key Points

To evaluate continuous beat-to-beat blood pressure and heart rate dynamics during active standing across different pediatric stages of development.
Monitored non-invasive continuous beat-to-beat blood pressure and heart rate using the Finapres 2300 device during active standing.
Assessed 173 schoolchildren (92 boys and 81 girls, aged 6–18 years; mean age 13.4 years) divided into prepubertal I, prepubertal II, pubertal, and young adult groups.
Pubertal and young adult groups experienced significantly greater initial drops in systolic BP (-36 ± 15% vs -15 ± 16%) and diastolic BP (-36 ± 14% vs -20 ± 19%) than prepubertal groups (p < 0.01).
Peak heart rate increases were significantly higher in the two older cohorts than in prepubertal children (34 ± 9 vs 29 ± 8 beats/min, p < 0.001), despite similar baroreflex indices across all groups.
The pubertal group exhibited a significantly smaller vasoconstrictor index, prolonged blood pressure recovery time, and the highest incidence of orthostatic hypotensive symptoms.

Structured PICO

Does age affect beat-to-beat blood pressure and heart rate responses to active standing in children?

Population

173 Japanese schoolchildren, 92 boys and 81 girls, aged 6-18 years (mean age: 13.4 years), divided into four age groups: prepubertal I (7-9 years), prepubertal II (10-12 years), pubertal (13-15 years) and young adult (16-18 years).

Intervention

Active standing monitored with a non-invasive continuous system (Finapres 2300)

Comparator

Comparison across four age groups (prepubertal I, prepubertal II, pubertal, young adult)

Outcome

Beat-to-beat blood pressure (BP) and heart rate (HR) responses to active standingsurrogate

Pubertal children demonstrate a larger initial drop in blood pressure and prolonged recovery time upon active standing compared to prepubertal children, indicating greater susceptibility to orthostatic stress.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May indicate greater orthostatic vulnerability around puberty; hypothesis-generating for age-specific pediatric norms, should not yet change practice.
