The effect of vagus nerve stimulation therapy on body mass index in children.

Published

Journal Article

The effects of vagus nerve stimulation on weight in individuals with epilepsy are not fully characterized. A retrospective review was performed of all pediatric patients who underwent placement of a vagus nerve stimulator at Duke University Medical Center. Baseline body mass index (BMI) percentile was compared with percentile on follow-up visits. We studied 23 patients who had undergone VNS placement during the period 2001-2009. Baseline BMI percentile was 61.7 ± 34.3. We had a power of 81% to detect a difference of 20 in BMI percentile from baseline to last follow-up. At the 1-year follow-up (mean=345 ± 112 days) and last follow-up (mean 4.2 ± 2.4 years) the average BMI percentile was 61.6 ± 31.88 and 56.09 ± 30.83, respectively. There was no significant difference in BMI percentile as compared with baseline at the 1-year and last follow-up visits (P=0.992 and 0.681, respectively). Long-term pediatric VNS therapy did not have a major clinically significant effect on BMI percentile during an average follow-up of more than 4 years.
