The relationship between diabetes-related knowledge and kidney disease knowledge, attitudes, and practices: a cross-sectional study

BACKGROUND: Diabetes mellitus (DM) is one of the main noncommunicable diseases encountered in primary health care clinics. DM is considered one of the most common causes of chronic kidney disease (CKD). In this study, we aimed to assess the knowledge, attitudes, and practices (KAP) of patients with DM on the early detection and prevention of CKD, determine its relationship with other variables, and examine the relationship between KAP scores for the prevention and early detection of CKD and the Michigan Diabetic Knowledge Test. METHODS: We collected data from 2 Nablus primary healthcare centers using a questionnaire that contains three sections: sociodemographic section, questions related to DM, and CKD screening index, which is formed of three scales. We used the Michigan Diabetic Knowledge Test (MDKT) to assess the knowledge of diabetic patients. RESULTS: The study was carried out among 386 diabetic patients with a mean age of 57.62 ± 12.4 years (ranging from 28 to 90). The median (interquartile range) was 11 (8–14) for the knowledge scale, 56 (52–59) for the attitude scale, and 30 (26–33) for the practice scale. In the multiple linear regression, only patients under 55 years old (p = 0.012), with normal BMI (p = 0.030), high educational level (p < 0.001), high monthly income (p = 0.020), and MDKT test score (p = 0.007) were significantly associated with higher knowledge score. Furthermore, patients who were over or equal to 55 years old (p = 0.007), had a high monthly income (p = 0.016), used a single oral diabetic drug (p = 0.003), had a total number of medications less than 4 (p = 0.010), and had a high knowledge and MDKT test were significantly associated with a higher attitude score. Finally, a patient with normal BMI (p = 0.002), city residency (p = 0.034), high educational level (p = 0.003), less frequent tobacco use (p < 0.001), last HbA1c (p = 0.023) and greater knowledge, attitude, and MDKT score were significantly associated with better practices toward CKD prevention and early detection. CONCLUSION: Regarding KAP analysis, higher practice scores for the prevention and early detection of CKD were significantly associated with patients with normal BMI, being city residents, high educational level, less tobacco use, last HbA1c below 7, and higher knowledge, attitude, and MDKT score.
