Background The prevalence of type 2 diabetes mellitus (T2D) and other NCDs is on the rise globally, low-income countries like Tanzania are not spared. Affordable and effective screening tools are needed to combat these epidemics. This study aimed to evaluate the utility and applicability of the Finnish Diabetes Risk Score (FINDRISC) as one of the screening tools for T2D and its potential risk factors in population of young adults from an urban setting in Tanzania. Methods A community based cross-sectional study was conducted in urban setting Mwanza-Tanzania. Data was collected using FINDRISC questionnaire (assessing Age, BMI, waist circumference, physical activity participation, vegetable consumption, and history of high blood pressure, history of high blood sugar and family history of diabetes) and physical assessment of, blood pressure, waist circumference and hip circumference. Laboratory measurements for fasting blood glucose, oral glucose tolerance and lipid profile. Data was analyzed using STATA 13. Pearson’s correlation was used to assess the associations between FINDRISC with clinical and biochemical parameters. Linear regression was used to assess the extent at which FINDRISC predicted various clinical and biochemical parameters. P-value was considered significant at p≤0.05. Results Of the 259 participants enrolled, 32.8% were in the FINDRISC categories of “at least slightly elevated risk” to “high risk” of developing T2D in 10 years’ time. FINDRISC correlated with FBG (r=0.12, p=0.05), diastolic blood pressure (r=0.19, p=0.02), mean arterial blood pressure (r=0.13, p=0.036), low density lipoprotein cholesterol (r=0.19, p =0.005), and waist to hip ratio - WHR (r=0.34, p = 0.001). Furthermore, FINDRISC explained 11% of the variation in WHR (Adjusted r2 = 0.11, p=0.001), 3% of diastolic blood pressure (adjusted r2= 0.03, p = 0.02), 3% of low density lipoprotein cholesterol (adjusted r2=0.03, p=0.005), 1% of mean arterial pressure (adjusted r2=0.01, p=0.036) and 1% of FBG (r2=0.01, p=0.05). Conclusion This study provides novel insights on the potential utility of FINDRISC as a simple and non-invasive screening tool for metabolic syndrome-related ailments among young adults in Africa. Longitudinal studies, with context-specific modifications of FINDRISC, are suggested to ascertain its predictive value for future T2D in this population.
