The prevalence estimates of hypertension obtained in this study was higher than those found in most earlier studies from Nigeria, other West Africa nations and for African-Americans.

There are a misconception and low level of awareness and knowledge of CKD, including those with risk factors, in the community. Efforts should be made to create awareness and educate people on CKD and prevention of its risk factors.

Objective:To compare the frequency of occurrence of metabolic syndrome using three international definitions and to study the distribution of cardiovascular risk factors among newly diagnosed hypertensive Nigerian subjects.Design: Cross sectional study.Settings: Cardiology unit of LAUTECH Teaching Hospital, Osogbo, Nigeria. Participants:One hundred forty newly diagnosed hypertensive Nigerian subjects, and 70 normotensive controls (age-and sex-matched) were included in this study. Methods:Clinical history and relevant laboratory investigations were performed on all study participants. The definition of metabolic syndrome was based on three international definitions: World Health Organization (WHO), International Diabetes Federation (IDF), and National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III). Ethical approval was obtained for the study. Statistical analyses were performed using SPSS 16.0.Results: There was no difference in age and gender distribution between the hypertensive subjects and controls. (55.14 ± 10.83 years, females 53.6% vs. 54.67 ± 10.89 years, females 52.9% respectively, P>0.05). The frequency of occurrence of metabolic syndrome among hypertensives was 34.5% according to WHO, 35.0% according to NCEP ATP III, and 42.5% according to IDF criteria. Visceral obesity and reduced high-density lipoprotein (HDL) were the other common cardiovascular risk factors among newly diagnosed hypertensive subjects. Female hypertensives had a higher prevalence of visceral obesity and low HDL. Conclusion:Frequency of occurrence of metabolic syndrome was similar using the NCEP ATP III and WHO definitions. However, the IDF definition resulted in a higher frequency because of the lower cut-off for waist circumference used for identification of visceral obesity. Metabolic syndrome is present in a significant proportion of newly diagnosed hypertensive subjects. Therefore, appropriate screening and treatment are required.
