A 2005 study by researchers at University of Newcastle upon Tyne (United Kingdom) found that men and women with a higher body fat and higher waist-hip ratio adults are more likely to have increased insulin resistance, a risk marker for type 2 diabetes.  Childhood factors, such as birth weight and nutrition, were found to have little impact in the risk for developing diabetes, discounting the notion that poor health in later life can result from earlier experiences.
