Impact of body size, nutrition and socioeconomic position in early life on the epigenome: a systematic review protocol

Abstract Background Body size, nutrition and socioeconomic position (SEP) in early life have been associated with a range of later life health outcomes. Epigenetic regulation is one mechanism through which these early life factors may impact later life health. The aim of this review protocol is to o...
