“…Furthermore, the perception “Developmental Origins of Health and Disease” (DOHaD), evolved from the “thrifty phenotype” explanation created by Barker in 1992, claimed that it is in the very early life, the stage of gestation, during which unfavorable environmental exposure can robustly pose a high incidence of chronic metabolism disorders, such as diabetes, obesity, dyslipidemia, etc., which persist in offspring into adulthood and even through generations [ 9 , 10 , 11 ]. Such an effect is brought about through epigenetic mechanisms, including DNA methylation, histone modifications, and noncoding RNAs [ 12 ], by altered intrauterine environment factors, including maternal nutrition status [ 13 ], lack of physical activities [ 13 , 14 ], circadian dysregulation [ 15 ], psychological stress [ 16 ], and tobacco smoking [ 17 ] during gestation.…”
