摘要

The study examines the factors associated with diarrhea prevalence in Yola of Adamawa State. Using Poisson regression model, while Quasi-Poisson and Negative Binomial were used to handle over dispersion. Pearson Chi-Square and Deviance was used to check for the goodness of fit. Data was extracted from the medical records of Adamawa State Specialist Hospital and Valli Clinic Yola. The variables on which the data were collected included sex, age group, year and hospital type. AIC of model 3 was selected as the least with AIC of 355.29. This model examines the interaction between hospital type and year of occurrence independent of age of patient, year and their gender. We found that male children are more likely to be infected with diarrhea compare to females. The study also revealed that as the children advanced in age, the rate of been infected with diarrhea decreases. The hospital type indicates that more patients infected with diarrhea visited Specialist hospital than Valli Clinic. The rate of infection increases every year but reduce in 2015 compared to 2014.
