This study models the relative risk of diabetes, taking obesity and malnutrition as the major risk factors to define exposure, using three different prevalence rates i.e. 3%, 7% and 11% (estimates and projections from various studies). Secondary data consisting of a sample population of 300 children from the Kenya Diabetes Management and Information Centre (DMI), a national central diabetes registry, databases is used. In this research project, the modified Poisson regression approach is used to directly estimate the relative risk of pediatric diabetes in age strata of patients aged between the ages of 0-14years inclusive and for the purpose of model comparison RR estimation is done using Poisson regression which will prove to be less desirable for assessment of risk in this study proving the modified Poisson model gives the best estimates. From the data used in this study it is evident that: exposure (being overweight or underweight) is not a risk factor for diabetes onset in children aged 0-14 years.
