Therefore, the presented study examined (a) TOC and TAC values and the oxidative stress index in non-obese children with PWS during the dietary intervention and growth hormone treatment in comparison with non-obese healthy children, (b) associations between the oxidant/antioxidant status and anthropometric and biochemical parameters including adipokines as well as dietary intake in children with PWS. Here, GH1 is linked to Prader-Willi syndrome.
