Increasing evidence links epigenetic variation to anthropometric and metabolic measures. Leptin signalling regulates appetite and energy expenditure, and in pregnancy is important for nutrient supply to the foetus. Maternal metabolic health and foetal growth are linked to infant blood leptin gene (LEP) methylation, which has been cross-sectionally associated with adolescent obesity. Despite this, few studies have explored the relationship between infant LEP methylation and childhood anthropometry, or the impact of genetic variation on these relationships. Using a prospective birth cohort, we investigated whether blood LEP promoter methylation at birth and 12 months predicts weight and adipos..
