A pretested questionnaire was used to collect data. The collected data was entered into SPSS version 20.0 software packages for statistical analysis. The data was analyzed using ordinal logistic regression to asses statistical significance association of dependent and independent variables. The degree of association between dependent and independent variables was assessed using the cross-tabulation with a 95% confidence interval and variables with pvalue ≤0.05 will be considered significant. The study population was composed of 186 females and 217 males. The dietary practice of diabetic patients assessed through 13 questions. The highest mean dietary practice score was obtained for the number of regular meals/day (2.60±.351).
