MedicalResearch.com: What is the background for this study?
Response: The concept that a mother's nutrition prior to and during pregnancy is important for health outcomes in the offspring is now well accepted. For example, women intending to get pregnant must take prenatal vitamins, and are encouraged to attain a healthy weight before conception. However, much less is known about how a father's nutritional status may influence childhood health outcomes. Based on studies in animals, exposure to undernutrition, high-fat diet, or stressful experiences in fathers can result in increased risk of obesity and diabetes in the offspring. These effects are mediated in part by epigenetic mechanisms (i.e. changes in gene expression due to differences in DNA methylation, histones, or other non-genetic mechanisms).

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: We started our work in the adverse outcome of maternal caffeine intake during pregnancy about 15 years ago. Then, we found that prenatal caffeine intake could result in nonalcoholic fatty liver disease in the offspring. However, the underlying mechanism was unclear.
So, we start the current work, and found that hat maternal caffeine intake disrupts liver development before and after birth, which might be the trigger of the adult non-alcoholic fatty liver disease in the offspring rats. Moreover, we further found that the fetal programming of liver glucocorticoid – insulin like growth factor 1 axis, a new endocrine axis first reported by our team, might participate in such process.
