Cardiometabolic disease in latin america: the role of fetal programming in response to maternal malnutrition.

Latin America is experiencing an epidemic of cardiovascular disease and type-2 diabetes mellitus. The rise in life-expectancy and increasingly rapid urbanization have resulted in a greater prevalence of overweight, obesity and metabolic syndrome. In Latin America, there is a high level of susceptibility to the development of insulin resistance and low-grade inflammation at relatively low levels of abdominal obesity. This susceptibility is associated with the adaptive response of the fetus to deficient fetal nutrition, which results in a loss of anatomical structures such as nephrons, cardiomyocytes and pancreatic beta cells. These adaptations may prove detrimental if food becomes abundant again after birth. In Latin America, the high prevalence of maternal and fetal malnutrition could mean that the resulting fetal adaptations may contribute to an increased risk of cardiometabolic disease. The socioeconomic differences that exist between developed and underdeveloped countries may be reflected in different biological adaptations, which could invalidate the diagnostic criteria and preventive and therapeutic approaches that have been recommended on the basis of research carried out in populations with different characteristics. Clinical studies are needed to evaluate the effectiveness of interventions recommended for preventing and aiding recovery from cardiometabolic disease in Latin America.
