    Prevalent components of metabolic syndrome and their correlates in apparently healthy individuals in Sub-Saharan Africa
    (2014) Charles-Davies, M. A.; Fasanmade, A. A.; Olaniyi, J. A.; Oyewole, O. E.; Owolabi, M. O.; Adebusuyi, J. R.; Hassan, O.; Ajobo, M. T.; Ebesunun, M. O.; Adigun, K.; Akinlade, K.

    Aim: To assess the prevalent components of metabolic syndrome (MSC) and their related determinants of lipid metabolism in the Nigerian for early diagnosis, prevention and management of the metabolic syndrome (MS) and its associated diseases. Study Design: Cohort study. Place and Duration of Study: Department of Chemical Pathology, College of Medicine, University of Ibadan, Ibadan between March and August 2010. Methodology: 534 apparently healthy Nigerian traders aged 18–105 years were participants of a cohort study. The IDF (2005) criteria was used for MS diagnosis. Anthropometric indices and blood pressure (BP) were obtained by standard methods. Fasting plasma glucose, total cholesterol (TC), triglycerides (TG) and high density lipoprotein cholesterol (HDLC) were determined by enzymatic methods while low density lipoprotein cholesterol (LDLC) was calculated. Data analysed were statistically significant at P<0.05. Results: 60.1% of traders had 2 and 3MSC. 0.6%, 1.1% and 9.6% of traders had all 5MSC, ≥3MSC without elevated waist circumference (WC) and zero MSC respectively. Elevated WC, reduced HDLC and high BP were more frequent MSC representing 70.2%, 63.1% and 47.9% while FPG and TG were less frequent representing 11.2% and 2.2% of traders respectively. This pattern was similar in MS and non-MS groups. 25.3% of males and only 2.2% of females had no MSC. Reduced HDLC and elevated WC were the most frequent MSC in males and females respectively. All metabolic risk factors (MRF) except TC were significantly different in comparison between MS and non-MS groups as well as among traders with 0-5 MSC. WHR was the only parameter that correlated significantly with all MRF. Conclusion: Elevated waist circumference, reduced high density lipoprotein cholesterol, and high blood pressure may be prevalent metabolic syndrome components and important in managing metabolic syndrome in Nigeria. Regional specific cut-offs for these components for the African population is needed.

    Indices of metabolic syndrome in 534 apparently healthy traders
    (David Publishing, 2012-02) Charles-Davies, M. A.; Arinola, O. G.; Fasanmade, A. A.; Olaniyi, J. A.; Oyewole, O. E.; Owolabi, M. O.; Hassan, O. O.; Ajobo, M. T.; Adigun, K.; Akinlade, K.

    Background: Metabolic Syndrome (MS) increases the risk of developing type-2 diabetes (DM2) and cardiovascular diseases (CVD) and it is thought to be prevalent in Nigeria. This study aims at determining the prevalence of MS and its component risk factors among apparently healthy traders in a local market in Ibadan, Nigeria. Methods: 534 apparently healthy traders from a local market in Bodija, Ibadan, Nigeria aged (18–105) years with neither DM2 nor CVD were participants of a cohort study on risk assessment of type 2 diabetes and dementia in Nigerians with metabolic syndrome. The International Diabetes Federation (2005) and the World Health Organisation (1998) criteria were used for MS and BMI respectively. Anthropometric indices (weight, height, body mass index (BMI), percentage body fat (PBF), waist and hip circumferences (WC & HC) and their ratio (WHR), waist circumference to height ratio (WHT)) and blood pressure (BP) were obtained by standard methods. Blood samples (6 ml) were obtained for the determination of glucose (FPG), total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C) by enzymatic methods while low density lipoprotein cholesterol (LDL-C) was calculated. Descriptive statistics, Chi-square test and ANOVA were among the analyses conducted. Results: 301 (56.4%) of traders studied were overweight (176, 33.0%) or obese (125, 23.4%) while 17 (3.4%) and 125 (40.4%) were underweight and normal weight respectively. The prevalence of MS and obesity were 87 (16.3%) and 125 (23.4%) respectively. There was significant association between obesity and MS (p < 0.05). Both MS and obesity were significantly associated with gender (p < 0.05). The prevalence of MS and obesity was higher in female (20.9%; 31.0%) than male traders (6.5%; 7.1%) respectively. The prevalence of MS increased from normal weight (8.3%) to overweight (18.8%) to obesity (28.8%). There were significantly higher differences in age, BP(systolic and diastolic), weight, BMI, WC, HC, WHT, WHR, and PBF but lower difference in height when overweight/obese groups were compared with normal weight group (p < 0.05). TC and LDL-C were significantly higher in only obese than normal weight traders. However, FPG, TG and HDL-C were similar in all groups (p >0.05). Conclusion: There is high prevalence of MS and obesity among Nigerian traders. Female gender, hypercholesterolemia, hypertension, increasing age, general and abdominal obesity appear to be important metabolic risk factors of CVD and not DM2 among Nigerian traders. Health care strategies for effective modulation of diet and lifestyle are needed urgently. In addition, screening programs for indices of MS in all Nigerians irrespective of BMI could be considered.
