INTRODUCTION: Having proper knowledge, attitude, and practices (KAP) towards chronic kidney disease (CKD) among type-2 diabetes mellitus (T2DM) patients is very important to reduce the disease burden. However, the information about KAP towards CKD among Bangladeshi T2DM patients is unknown, based on the available literatures till the date. OBJECTIVES: We aimed to assess the KAP towards CKD among T2DM patients attended a selected hospital in Dhaka city. METHODS AND MATERIALS: In this cross-sectional study, we conveniently selected Aalok hospital and also its 224 T2DM patients who attended the outdoor. We excluded the already developed CKD patients and aged over 70 years. We adopted a questionnaire from a validated instrument consisted of a 10 itemed knowledge, 8 itemed attitude, and 7 itemed practice domains towards CKD (total 25 items). Data were collected by face-to-face interviews. Both descriptive and comparative (Independent Sample t-tests and One-way ANOVA tests) statistics were used for data analysis where appropriates. RESULTS: Women respondents were higher (69.6%). The mean age of the respondents was 49.8±11.3 years. Most of them had average level of knowledge (69.6%) and attitude (60.7%). Majority also reported a good hypothetical practices in general if they would find out to have CKD. Knowledge was significantly associated (p<0.05) with sex, level of education, occupation, and income, whereas attitude was with sex, occupation, and income. CONCLUSION: T2DM patients of our study reported mostly average level of knowledge and attitude, and a good hypothetical practices in general towards CKD. Proper health awareness programs are needed to increase the KAP towards CKD among T2DM patients in Bangladesh.
