RESUMO
This study aimed to investigate trends in the estimated 10-year risk for developing cardiovascular disease [CVD] among adults with diagnosed diabetes in Oman. In addition, the effect of hypothetical risk reductions in this population was examined. Data from 1,077 Omani adults aged >/=40 years with diagnosed diabetes were collected and analysed from three national surveys conducted in 1991, 2000 and 2008 across all regions of Oman. The estimated 10-year CVD risk and hypothetical risk reductions were calculated using risk prediction algorithms from the Systematic COronary Risk Evaluation [SCORE], Diabetes Epidemiology Collaborative Analysis of Diagnostic Criteria in Europe [DECODE] and World Health Organization/International Society of Hypertension [WHO/ISH] risk tools. Between 1991 and 2008, the estimated 10-year risk of CVD increased significantly in the total sample and among both genders, regardless of the risk prediction algorithm that was used. Hypothetical risk reduction models for three scenarios [eliminating smoking, controlling systolic blood pressure and reducing total cholesterol] identified that reducing systolic blood pressure to
