Dysregulation of the Autonomic Nervous System Predicts the Development of the Metabolic Syndrome
Key result
Increased sympathetic activity predicted an increase in metabolic abnormalities over 2 years, suggesting autonomic dysregulation is a predictor of cardiovascular disease and diabetes.
Why the study?
Does dysregulation of the autonomic nervous system predict the development of metabolic syndrome in adults?
Key Points
- This study aims to evaluate whether autonomic nervous system functioning can predict the development of metabolic abnormalities over two years.
- Prospective cohort study using data from the Netherlands Study of Depression and Anxiety.
- Baseline and 2-year follow-up assessments conducted with 1933 participants aged 18-65 years.
- Outcome measures included autonomic nervous system metrics like heart rate, respiratory sinus arrhythmia, pre-ejection period, cardiac autonomic balance, and cardiac autonomic regulation.
- Baseline short PEP and low CAB predict an increase in metabolic syndrome components during follow-up.
- High HR and low CAB predict a decrease in HDL cholesterol and increases in blood pressure over two years.
- Low baseline RSA predicts subsequent decreases in HDL cholesterol.

P
Population
1,933 participants aged 18-65 years from the Netherlands, followed for 2 years to assess whether autonomic nervous system functioning predicts the development of metabolic syndrome.
E
Exposure
Autonomic nervous system measures including heart rate (HR), respiratory sinus arrhythmia (RSA), pre-ejection period (PEP), cardiac autonomic balance (CAB), and cardiac autonomic regulation (CAR)
O
Outcome
2-year development of metabolic abnormalities constituting the metabolic syndrome (based on updated Adult Treatment Panel III criteria)surrogate
Increased sympathetic activity and dysregulation of the autonomic nervous system predict the development of metabolic syndrome components over 2 years.

Implication
Autonomic dysregulation may predict metabolic worsening; hypothesis-generating and requires prospective confirmation before practice change.

Licht et al. (2013) conducted a cohort in Metabolic syndrome (n=1,933). Autonomic nervous system dysregulation was evaluated on Development of metabolic abnormalities constituting the metabolic syndrome. Increased sympathetic activity predicted an increase in metabolic abnormalities over 2 years, suggesting autonomic dysregulation is a predictor of cardiovascular disease and diabetes.
