The epidemic of metabolic syndrome, including a marked increase in the prevalence of obesity and gestational diabetes mellitus among pregnant women, represents a significant public health problem. Both weight gain and body mass index are major predictors of diabetes; for every 1 kg increase in adult weight, the risk of diabetes increases by 4.5 to 9%. Although genetic factors may contribute to selected cases of obesity, environmental and epigenetic factors are likely more important. There is increasing recognition that the risk of adult obesity is clearly influenced by prenatal and infant environmental exposures. This tenet is the fundamental basis of developmental programming. Low birth weight, together with infant catch-up growth, is associated with a significant risk of adult obesity and type II diabetes. As an index of the public health significance, a striking 57% of type II diabetes can be attributed to programmed metabolic syndrome. Animal models have replicated human epidemiologic findings and elucidated potential programming mechanisms that include altered organ development, cellular signaling responses, and epigenetic modifications. Adipose tissue is one of the principal targets of programming that predisposes to offspring obesity. Our studies show that newborns of obese/high fat diet mothers and low birth weight newborns of maternal under-nutrition both exhibit programmed adipocytes that contribute to the development of obesity. These adipocytes have intrinsic trait of increased cell proliferation and enhanced propensity for fat storage. Knowledge of the mechanisms of fetal adipocyte programming will enable the development of novel therapeutics to prevent obesity and glucose intolerance.
