ObjectiveTo investigate the current situation of ketogenic diet treatment centers in China, including the target, quantity, indication diseases, staffing and regional distribution of ketogenic diet therapy centers.MethodsMembers from the China Association Against Epilepsy (CAAE) received an investigation on the development situation of ketogenic diet therapy in their own epilepsy centers through an online survey. ResultsAt present, there are 91 centers for ketogenic diet therapy in China, and among them, there are 74 centers (81.32%) only treat pediatric patients. 59 centers of them (64.83%) were established between 2010 and 2020; patients of 63 centers (69.23%) have been treated with ketogenic therapy for status epilepticus (SE), among which only 9 centers (14.29%) have 5 or more epileptic patients on averge per month. 35 centers (38.46%) are offering ketogenic diet treatment for indications other than epilepsy. The main diseases are autism spectrum disorder, encephalitis, febrile infection related epilepsy syndrome (FIRES), rare diseases and glycolipid metabolic diseases. All ketogenic diet treatment centers are equipped with high-quality professionals, mainly neurologists and pediatric physicians; There are significant differences in regional distribution, with centers in the eastern region accounting for more than half (53.85%). ConclusionsThe development of ketogenic diet therapy in China has achieved initial results, but there are still some problems such as small number of patients treated and uneven geographical distribution.
