Abstract
The study is aimed at finding out the relationship between diabetes with hypertension and other cardiovascular risk factors among diabetic patients at Komfo Anokye Teaching Hospital, Kumasi. The main purpose is to model the relation between hypertensive diabetic and significant risk factors. Among the 310 subjects randomly selected, 198 were hypertensive diabetics with 147(74%) females. The data analysis was executed by SPSS with logit and probit analysis used for modeling. Findings revealed that the best predictor variables for diabetes with hypertension using the above analysis are age, body mass index (BMI) and blood glucose level (BGL) with their respective odds ratios 1.113, 1.266 and 0.937. Based on this, two similar models- logit and probit are developed for assessing the risks associated with hypertensive diabetic and also to make future predictions. Logit (Y) = 1n (𝜋1− ) = -10.581+ 0.107Age + 0.236BMI + (-0.065BGL) and Probit( 𝜋𝑖) = Φ[(-3.758) + 0.026Age + 0.058BMI + (-0.024BGL)]
