Key result
Malnourished children presented reductions in sympathetic and parasympathetic activity (lower SDNN, rMSSD, LF, HF), increased heart rate, and decreased blood pressure compared to eutrophic children.

Malnutrition associated with reduced HRV in children; hypothesis-generating and requires longitudinal studies before clinical implications.
Observational (n=70)
Does malnutrition alter cardiac autonomic modulation and heart rate variability in children?
Malnutrition in children is associated with depressed sympathetic and parasympathetic cardiac autonomic modulation, alongside increased heart rate and decreased blood pressure.
Barreto et al. (2016) conducted an observational in Malnutrition (n=70). Malnutrition vs. Eutrophic children was evaluated on Heart rate variability (HRV) indices, heart rate, and blood pressure. Malnourished children presented reductions in sympathetic and parasympathetic activity (lower SDNN, rMSSD, LF, HF), increased heart rate, and decreased blood pressure compared to eutrophic children.
