    Using Gastroschisis To Demonstrate Research Study Designs

    Research studies provide a link between surveillance and prevention programs in the public health framework. This session provided an overview of the methods used in descriptive and analytic public health research studies using gastroschisis, a herniation of the intestines from the anterior abdominal wall, as an example. It was stressed that while descriptive studies focus on describing the characteristics of a population and the extent of a disease, an analytic study focuses on risk factors and seeks to find possible methods of intervention.
