RESUMO
BACKGROUND: Professional drivers are known to be at high risk for cardiovascular disease (CVD) on account of the higher prevalence co-occurring risk factors they harbour. Chronic kidney disease (CKD) and CVD share similar risk factors. Both impact each other adversely. The renal profile of professional drivers in Nigeria is not well characterised. We decided to study the prevalence of positive CKD screening amongst professional male long distance drivers in Lagos, Southwest Nigeria so as to quantify the burden and its predictors. METHODS: Two hundred and ninety-three drivers were recruited. Details of their socio-demographic characteristics were obtained. Their anthropometric indices, blood pressure, fasting plasma blood glucose and lipid profile were measured. Serum creatinine was measured and estimated glomerular filtration rate, eGFR, was calculated with Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Urinary Albumin Creatinine Ratio (UACR) was determined. A 10 year CVD risk of the subjects was calculated with the Framingham Risk Score (FRS). RESULTS: Mean age of the study population was 44.8 + 9.7 years. The prevalence of alcohol use and smoking were 71.0 and 19.5% respectively. One hundred and twenty-one (62.8%) of the subjects were either overweight or obese while 70(24.1%) had abdominal obesity. The prevalence of hypertension and diabetes were 39.7 and 13.9% respectively. Prevalence of CKD by eGFR< 60 ml/min/1.73m2 or UACR > 30 mg/g was 51.7% (95% CI; 46.0-57.5). The odds for CKD increased with lower HDL-c levels; OR 3.5 (95% CI, 1.1-11.2; p = 0.03) and longer duration of professional driving > 20 years; OR 2.4(95% CI, 1.5-4.0). CONCLUSION: Professional male long distance drivers in addition to having very high prevalence of clustering of both CVD and CKD risk factors have a significant burden of asymptomatic CKD. UACR appears to be an earlier marker of CKD in this population. Health awareness promotion and aggressive risk factor reduction are advocated as ways to reduce this burden.

BACKGROUND: Simultaneous presence of elevated waist circumference and hypertriglyceridemia (HTGW) is a simple and low-cost measure of visceral obesity, and it is associated with a plethora of cardio-metabolic abnormalities that can increase the risk of cardiovascular diseases and incident Type 2 diabetes mellitus. We decided to study the prevalence, patterns, and predictors of metabolic abnormalities in Nigerian hypertensives with the HTGW phenotype. METHODS: The medical records of 582 hypertensives with complete data of interest were retrieved and analyzed for the study. Their socio-demographic data, anthropometric data, and booking blood pressure values were retrieved. The results of their fasting plasma glucose, lipid profile, uric acid and serum creatinine were also retrieved for analysis. RESULTS: The mean age of the study population was 56.2 ±13.6, with 53.1% being males. The prevalence of smoking and use of alcohol was 4.3% and 26.5% respectively. The prevalence of the HTGW phenotype was 23.4% and were predominantly males (61%). Subjects with the HTGW phenotype were more obese assessed by waist circumference (WC) and body mass index (BMI). Mean serum total cholesterol, triglyceride, very low-density lipoprotein, uric acid, and creatinine were significantly higher in the HTGW phenotype (p = 0.003; <0.001; <0.001; 0.002 and <0.001 respectively). The prevalence of newly diagnosed Type 2 diabetes was 28.7%. There was also a preponderance of cardio-metabolic abnormalities (obesity, dyslipidaemia, hyperuricemia) in the HTGW phenotype. In both males and females, the HGTW phenotype was significantly associated with elevated Tc, TG, VLDL, hyperuricemia and atherogenic index of plasma. CONCLUSION: The HTGW phenotype is common amongst Nigerian hypertensives, and it is associated with metabolic abnormalities.
RESUMO
Hypertension is the most prevalent cardiovascular disorder in the world. It is associated with target-organ damage in various organs and ECG changes. P-wave dispersion (PWD), which represents inhomogeneous atrial conduction and discontinuation of impulses, has been observed, when prolonged, to predict atrial fibrillation, particularly in the setting of hypertension. This study of PWD in 150 hypertensive patients and controls sought to determine the prevalence of PWD in Nigerian hypertensives and its relationship to left ventricular mass index and left ventricular function. Mean PWD in normal subjects was 32.14 ± 4.72 ms and was significantly shorter than that in hypertensive patients at 38.29 ± 8.02 ms. In the total population, 51.3% had prolonged PWD ( > 33.46 ms); 70% in the hypertensives and 32.7% of controls. The only significant difference in hypertensives with prolonged and normal PWD was the waist circumference. There was a negative correlation between PWD and ejection fraction (r = -0.17, p = 0.03), but not with diastolic function.

RESUMO
Background Studies in international literature have shown that Community Pharmacists can make considerable impact in controlling cardiovascular disease risk factors, especially hypertension. In Nigeria, there are no studies on the knowledge of CVD risk factors by Community Pharmacists and their practice of primary prevention. Objective To assess the knowledge of CVD risk factors and practice of primary prevention of CVD amongst Nigerian community pharmacists. Setting Community Pharmacists in Lagos, Nigeria. Methods This cross-sectional study involved 168 Community Pharmacists. Their knowledge of CVD risk factors was assessed with the Heart Disease Fact Questionnaire. Their opportunistic screening practices for CVD risk factors (primary prevention) were also assessed. Main outcome measures Knowledge of CVD risk factors and practice of primary CVD prevention. Results The mean age of the participating pharmacists was 41.7 (± 11.2) years and 87 (51.8%) of them were males. The median number of years of practice was 9.0 (3-15) years. Mean knowledge score was 22.1 (± 3.0) with 154 (91.7%) of the subjects scoring above 70%. An average of 95.5% of the participants correctly identified hypertension, smoking, dyslipidaemia, obesity, physical inactivity and diabetes as CVD risk factors. Eighty-one (48.2%) had good practice of primary CVD prevention. Conclusion: This study shows that Community Pharmacists in Nigeria have very good knowledge level of CVD risk factors and almost 50% of them practised primary prevention of CVD.

Cooking with dirty-burning fuels is associated with health risk from household air pollution. We assessed the prevalence of and factors associated with the use of cooking fuels, and attitudes and barriers towards use of liquefied petroleum gas (LPG). This was a cross-sectional, population-based survey conducted in 519 households in Lagos, Nigeria. We used a structured questionnaire to obtain information regarding choice of household cooking fuel and the attitudes towards the use of LPG. Kerosene was the most frequently used cooking fuel (n = 475, 91.5%; primary use n = 364, 70.1%) followed by charcoal (n = 159, 30.6%; primary use n = 88, 17%) and LPG (n = 86, 16.6%; primary use n = 63, 12.1%). Higher level of education, higher income and younger age were associated with LPG vs. kerosene use. Fuel expenditure on LPG was significantly lower than for kerosene ( N (Naira) 2169.0 ± 1507.0 vs. N 2581.6 ± 1407.5). Over 90% of non-LPG users were willing to switch to LPG but cited safety issues and high cost as potential barriers to switching. Our findings suggest that misinformation and beliefs regarding benefits, safety and cost of LPG are important barriers to LPG use. An educational intervention program could be a cost-effective approach to improve LPG adoption and should be formally addressed through a well-designed community-based intervention study.

BACKGROUND: Professional drivers are known to be at high risk of cardiovascular disease (CVD). This study was carried out to highlight these risk factors and their predictors among male long-distance professional bus drivers in Lagos, south-west Nigeria, with a view to improving health awareness in this group. METHOD: Socio-demographic data, anthropometric indices, blood pressure, fasting plasma blood glucose levels and lipid and physical activity profiles of 293 drivers were measured. RESULTS: Mean age of the study population was 48 ± 9.7 years; 71.0 and 19.5% of the drivers used alcohol and were smokers, respectively; and 50.9% were physically inactive. The prevalence of overweight and obesity was 41.7 and 21.1%, respectively, while 39.7 and 13.9% were hypertensive and diabetic, respectively. Ninety (31.3%) subjects had impaired fasting glucose levels while 56.3% had dyslipidaemia. Predictors of hypertension were age and body mass index (BMI). BMI only was a predictor of abnormal glucose profile. CONCLUSION: Professional male long-distance bus drivers in this study showed a high prevalence of a cluster of risk factors for CVD.

BACKGROUND: Factors associated with tobacco smoking are useful in designing tobacco control programs. OBJECTIVES: To estimate the prevalence of and factors associated with tobacco smoking among long-distance drivers. METHODS: This was a cross-sectional study. Stratified cluster sampling approach was used to select drivers based on if they received annual health screening (AHS) or not (non AHS). We used a structured questionnaire to obtain information and weighted the resulting observations to derive population based estimates. Association between tobacco smoking and socio-demographic factors was explored in multivariate models. RESULTS: 414 male drivers, mean age 43.6 (standard error 0.6) years. Population weighted prevalence of current smoking was 18.9% (95% CI: 14.3-23.4) of all drivers, 6.5% (95% CI: 2.6-10.4) of AHS drivers and 19.5 (95% CI: 14.7-24.2) of non AHS drivers (p<0.001). In multivariate models, having close friends that smoked (OR= 6.36, 95% CI= 2.49 - 16.20) cargo driving (OR= 2.58, 95% CI= 1.29 - 5.15) and lower education levels (OR for post-secondary education vs. primary education or less= 0.17, 95% CI= 0.04 - 0.81) were associated with current smoking. CONCLUSION: Prevalence of tobacco smoking is higher among non AHS compared to AHS drivers. Having close friends that smoked, cargo driving, and lower education levels were associated with current smoking.
