I'm Dr. Jess Buxton. I'm a researcher based at University College in London. My work involves investigating how genetic and environmental factors interact to affect disease risk. In this lecture, I'm going to be talking about the role of fetal programming in obesity.

So during this lecture, I'm going to describe what fetal programming is, and how it fits into the thrifty phenotype hypothesis in the wider research area of DOHaD. I'm going to also consider animal models of fetal programming, and some possible epigenetic mechanisms that explain this phenomenon. And finally, I'm going to look at the evidence for transgenerational effects of fetal programming.

So what causes obesity? We know that the causes are a complex mix of genetic and environmental factors, and an interaction between the two, often, including diet and low levels of physical activity. We also know that some genetic variations are involved and affect a person's risk of developing obesity. This talk is going to focus on the role of prenatal factors. So factors before birth that might affect our future risk of obesity in childhood and adulthood.
