The long-term effects of certain clinical factors on cognition cannot be overemphasized. The morbidity of Cognitive Impairment (CI) in patients with type 2 diabetes has been found to increase when associated with some clinical factors. The main objective of this study was to determine the relationship between CI and Body Mass Index (BMI) as well as CI and Blood Pressure (BP), among type 2 diabetic patients attending the primary care unit of a tertiary hospital. It was a descriptive hospital-based crosssectional study. Ethical approval was obtained from the Ethical Review Committee of the University of Ilorin Teaching Hospital (UITH) before the commencement of the study. Data was collected from 274 adult type 2 diabetic patients attending the Family Medicine clinics of the hospital, from March through May 2017. Interviewer-administered structured and semi-structured questionnaires were used to obtain information from the respondents. The Mini-Mental State Examination (MMSE) was used to assess CI among respondents. The BMI and BP of participants were obtained following standard procedure. Data was collated and analyzed using the Statistical Package for Social Sciences version 21 (SPSS- 21). The elderly constituted a higher proportion of participants 55.4%. Respondents were mainly females (70.8%), married (78.8%), and educated (78.1%). The clinical factor that had a statistically significant association with CI was the BMI of participants with a chi-square value (χ2) of 11.139 and a p-value of 0.048. Blood pressure had no statistically significant association with CI (χ2 of 5.181 and p-value of 0.159). CI is common in our clinics with a prevalence of 27% seen in this study. BMI had a statistically significant association with CI while BP was not. Hence, maintaining a normal weight may help in controlling CI. Physicians in primary care should routinely screen type 2 diabetic patients for CI as well as control risk factors for it.
