Background: Diabetes is a multifactorial disease state that requires adequate patient monitoring for improved health outcomes. Diabetes knowledge and attitude, and associated factors such as medication adherence, medication discrepancy, health literacy, and glycemic control were evaluated in this study. The selected factors were also compared with diabetes knowledge and attitude.
Methods: A cross-sectional study was carried out among ambulatory diabetes patients in three tertiary healthcare facilities in Nigeria. An interviewer-administered semi-structured questionnaire was utilized for data collection. Data was analysed using descriptive and inferential statistics with the level of significance set at p < 0.05.
Results: A total of 188 diabetes patients participated in the study; 51 (27.1%) at the Federal Medical Center, Abeokuta, 69 (36.7%) at the University College Hospital, Ibadan, and 68 (36.2%) at the University of Ilorin Teaching Hospital, Ilorin. One hundred and twelve (59.6%) female patients participated in the study and patients' average age was 58.69 ± 13.68 years. Medication discrepancy was observed among 101 (53.7%) patients. One hundred and three (54.8%), 47 (25.0%) and 38 (20.2%) had high, medium, and low medication adherence, respectively. Ninety-one (48.4%) had high health literacy. Mean diabetes knowledge score was 14.64 ± 2.55 points out of a maximum obtainable score of 18 points. Mean diabetes attitude of patients was 62.50 ± 6.86 points out of a maximum obtainable score of 70 points. Significant positive association was observed between diabetes knowledge and health literacy (Beta = 0.021, p = 0.029). Diabetes knowledge was higher in patients with higher level of formal education (p = 0.046), higher diabetes attitude (p < 0.001) and high health literacy (p = 0.002). Patients' diabetes attitude was higher in individuals older than 60 years of age (p = 0.029), and those with high health literacy (p = 0.005).
Conclusions: The diabetes patients displayed good disease knowledge, attitude and medication adherence. Average levels of health literacy and medication discrepancy was observed among the patients. Significant differences were observed between patients' diabetes knowledge and level of formal education, diabetes attitude, health literacy and age. Patients' health literacy was significantly associated with diabetes knowledge.
