The relationship between obesity and sedentary behavior on the one hand and cardiometabolic diseases on the other hand had been well established. To be used as screening tools for cardiometabolic disease, such risk factors must demonstrate sufficient discriminatory capacity as measured by area under the curve (AUC) of receiver operating characteristics curve (ROC). The aim of this study is to compare the performance of sitting time and obesity measures as screening tools for prehypertension among selected workers in Kano State Nigeria. This is a cross sectional analytical study conducted among workers enrolled in a part-time degree program at Bayero University Kano, Kano State, Nigeria. Body weight was measured using a digital weighing scale, height using a portable stadiometer, circumferences (waist and hip) using an inelastic tape and blood pressure using a mercury sphygmomanometer. Sitting time was reported using a standard questionnaire. The ROC analysis showed the cut off points of body mass index, waist circumference and sitting time were respectively 24kg/m2 for males and 26kg/m2 for females, 84cm for both sexes and 8 hours for males and 9 hours for females. The respective AUCs were respectively 59%, 61% and 58%. In conclusion, sitting time has performance comparable to that of body mass index in predicting prehypertension among the study subjects.
