An animal study showed that IL-1β production decreased in malnourished guinea pigs induced with endotoxins.19 Stunting is a form of growth failure due to long term nutritional deficiency or it is caused by chronic malnutrition or recurrent undernutrition.8,67 After a six month intervention with food supplementation, stunted Bangladeshi children aged 12–18 months old experienced an IL-6 increment (from 0 [0–1.2] to 1.68 [0.83–4.7] pg/mL, p = 0.001),68 which contradicts this study as IL-6 levels were reduced in stunted and normal stature children. This evidence concerns the gene IL6 and nutritional deficiency disease.
