Obesity and cardio-metabolic risk factors in urban adults of Benin: Relationship with socio-economic status, urbanisation, and lifestyle patterns

<p>Abstract</p> <p>Background</p> <p>There is a dearth of information on diet-related chronic diseases in West Africa. This cross-sectional study assessed the rate of obesity and other cardiovascular disease (CVD) risk factors in a random sample of 200 urban adults in Benin and explored the associations between these factors and socio-economic status (SES), urbanisation as well as lifestyle patterns.</p> <p>Methods</p> <p>Anthropometric parameters (height, weight and waist circumference), blood pressure, fasting plasma glucose, and serum lipids (HDL-cholesterol and triglycerides) were measured. WHO cut-offs were used to define CVD risk factors. Food intake and physical activity were assessed with three non-consecutive 24-hour recalls. Information on tobacco use and alcohol consumption was collected using a questionnaire. An overall lifestyle score (OLS) was created based on diet quality, alcohol consumption, smoking, and physical activity. A SES score was computed based on education, main occupation and household amenities (as proxy for income).</p> <p>Results</p> <p>The most prevalent CVD risk factors were overall obesity (18%), abdominal obesity (32%), hypertension (23%), and low HDL-cholesterol (13%). Diabetes and hypertriglyceridemia were uncommon. The prevalence of overall obesity was roughly four times higher in women than in men (28 vs. 8%). After controlling for age and sex, the odds of obesity increased significantly with SES, while a longer exposure to the urban environment was associated with higher odds of hypertension. Of the single lifestyle factors examined, physical activity was the most strongly associated with several CVD risk factors. Logistic regression analyses revealed that the likelihood of obesity and hypertension decreased significantly as the OLS improved, while controlling for potential confounding factors.</p> <p>Conclusion</p> <p>Our data show that obesity and cardio-metabolic risk factors are highly prevalent among urban adults in Benin, which calls for urgent measures to avert the rise of diet-related chronic diseases. People with higher SES and those with a longer exposure to the urban environment are priority target groups for interventions focusing on environmental risk factors that are amenable to change in this population. Lifestyle interventions would appear appropriate, with particular emphasis on physical activity.</p

Four-Year Trends in Cardiometabolic Risk Factors according to Baseline Abdominal Obesity Status in West-African Adults: The Benin Study

The study examined whether abdominal obesity (AO) according to waist circumference was associated with more unfavourable changes in other cardiometabolic risk (CMR) factors in sub-Saharan Africans. The study included 541 randomly selected and apparently healthy subjects (50% women) aged 25–60 years. Complete data at baseline, 24, and 48 months later was available in 366 subjects. AO was associated with higher CMR at baseline and over the follow-up period, except for high blood pressure. A significantly higher incidence of high ratio of total cholesterol : HDL-cholesterol (TC/HDL-C) was associated with AO. Controlling for WC changes, age, baseline diet, and lifestyles, the relative risk (RR) of low HDL-C and high TC/HDL-C was 3.2 (95% CI 1.06–9.61) and 7.4 (95% CI 2.01–25.79), respectively, in AO men; the RR was not significant in women. Over a four-year period, AO therefore appeared associated with an adverse evolution of cholesterolemia in the study population

Performances comparées du HDL-cholestérol et du ratio cholestérol total/HDL pour le dépistage du syndrome métabolique chez des adultes du Sud-Bénin (Afrique de l’Ouest)

Les critères de définition du Syndrome métabolique (SMet) n’identifient pas convenablement les sujets d’origine africaine à risque. L’objectif était de déterminer lequel du ratio cholestérol total/HDL-cholestérol (CT/HDL-C) et du HDL-Cholestérol est le meilleur prédicteur du SMet chez les adultes béninois. L’étude de type transversal, issue d’une enquête longitudinale sur le risque cardiométabolique a inclu 416 sujets âgés de 29 à 69 ans. Les composantes du SMet considérées sont : l’obésité abdominale, la tension artérielle élevée, la glycémie élevée, le HDL-C bas et les triglycérides élevés. La comparaison des aires sous les courbes (AUC) de la « fonction d’efficacité du récepteur » (ROC) de prédiction de l’existence deux composantes du SMet autre que l’obésité abdominale, a permis de déterminer le meilleur prédicteur. Les prévalences du SMet étaient de 13,9% selon la définition harmonisée, 12,3% lorsque le HDL-C bas est remplacée par CT/HDL-C élevé. Les prévalences du HDL-bas et du CT/HDL-C élevé sont de 37,7% et 22,6%, respectivement. Pour le dépistage du SMet, l’AUC du CT/HDL-C est de 0,69 (IC 95% 0,61-0,77) chez les femmes et 0,68 (IC 95% 0,59-0,77) chez les hommes. L’AUC du HDL-C est de 0,45 (IC 95% 0,37-0,53) chez les femmes et 0,40 (IC 95% 0,30-0,44) chez les hommes. Le HDL-C et le CT/HDL-C ont une faible capacité prédictive pour le SMet, mais la composante CT/HDL-C prédit mieux le SMet que le HDL-C isolé. Toutefois, l’utilisation de l’un ou l’autre des deux paramètres ne modifie pas substantiellement la prévalence du SMet dans la population d’étude.© 2016 International Formulae Group.

The objective was to determine which of total cholesterol/HDL-cholesterol (TC/HDL-C) and HDL-cholesterol is the best predictor of metabolic syndrome (SMet) in Benin adults. This cross-sectional study was nested in a four-year follow-up study on cardiometabolic risk factors and included 416 adults aged 29-69 years. Components of MetS considered were abdominal obesity, high blood pressure (BP), high fasting glucose, low HDL-C and high triglycerides. Areas under the "Receiver operator characteristic" curves (AUC)for CT/HDL-C and HDL-C in predicting the presence of at least two other components of SMet were compared in order to determine the best predictor of SMet. The prevalence of SMet was 13.9%, when replacing low HDL-C by high TC/HDL-C and 15.3% when both dyslipidemia indicators are combined. The prevalence of low HDL-C and high TC/HDL-C was 37.7% and 22.6%, respectively (p&lt;0.001). Screening for SMet, the AUC of TC/HDL-C were 0.69 (95% CI 0.61-0.77) for women and 0.68 (95% CI 0.59-0.77) in men. The AUC of HDL-C were 0.45 (95% CI 0.37-0.53) for women and 0.40 (95% CI 0.30-0.44) for men. Both TC/HDL-C and HDL-C showed some weak predictive values for SMet, but TC/HDL-C ratio predicted SMet better than HDL-C.© 2016 International Formulae Group.

Respiratory symptoms associated with workplaces located along a road with high-traffic at Cotonou, Benin

Living or working along a main road with high traffic is harmful to health. The results of a logistic regression model show the presence of cough and itchy nose are highly significantly associated with location. The study shows there is a difference in the risk of respiratory symptoms working near traffic island roundabouts and outside roundabouts (defined as a traffic circle or road junction at which traffic moves in one direction around a central island to reach the converging roads). For the three roundabouts in the study (located downtown), with the most companies in town, there is heavy traffic observed especially at hours when businesses return to service

Determinants of Adherence to Recommendations of the Dietary Approach to Stop Hypertension in Adults with Hypertension Treated in a Hospital in Benin

Abstract The dietary approach to stop hypertension (DASH) is an effective nutritional strategy to prevent and treat cardiovascular disease. Optimal benefit from dietary recommendations in management of hypertension depends on the compliance. This analytic cross sectional study aimed at establishing determinants of DASH among adults with hypertension treated at hospital in Benin. The study included 150 hypertensive adults selected during medical visit for blood pressure monitoring at hospital Saint-Luc in Cotonou from June 3 rd to July 1 st , 2014. Data on consumption of sodium, fruits and vegetables, alcohol, saturated and trans fat rich products were collected by questionnaire. A score of adherence to DASH was built. Determinants of adherence to DASH were identified using logistic regression model. Only 20% of subjects showed adherence to DASH. Better knowledge on hypertension OR=5.18 (95%IC 1.98-13.22) and healthy dietary habits and lifestyle prior to diagnosis of hypertension OR=4.26 (95%IC 1.67-13.18) increased the likelihood of adherence to dietary recommendations for hypertension management. Nutrition education and information of patients on hypertension and its complications during medical consultations may increase their adherence to dietary recommendations for management of the disease

Partnership research on nutrition transition and chronic diseases in West Africa – trends, outcomes and impacts

Abstract Background Nutrition-related chronic diseases (NRCD) are rising quickly in developing countries, and the nutrition transition is a major contributor. Low-income countries have not been spared. Health issues related to nutritional deficiencies also persist, creating a double burden of malnutrition (DBM). There is still a major shortage of data on NRCD and DBM in Sub-Saharan Africa. A research program has been designed and conducted in partnership with West African institutions since 2003 to determine how the nutrition transition relates to NRCD and the DBM in order to support prevention efforts. Methods In Benin, cross-sectional studies among apparently healthy adults (n=540) from urban, semi-urban and rural areas have examined cardiometabolic risk (hypertension, obesity, dyslipidemia, insulin resistance) in relation to diet and lifestyle, also factoring in socio-economic status (SES). Those studies were followed by a longitudinal study on how risk evolves, opening the way for mutual aid groups to develop a prevention strategy within an action research framework. In Burkina Faso, a cross-sectional study on the nutritional status and dietary patterns of urban school-age children (n=650) represented the initial stages of an action research project to prevent DBM in schools. A cross-sectional study among adults (n=330) from the capital of Burkina Faso explored the coexistence, within these individuals, of cardiometabolic risk factors and nutritional deficiencies (anemia, vitamin A deficiency, chronic energy deficiency), as they relate to diet, lifestyle and SES. Results The studies have shown that the prevalence of NRCD is high among the poor, thereby exacerbating social inequalities. The hypothesis of a positive socio-economic (and rural–urban) gradient was confirmed only for obesity, whereas the prevalence of hypertension, insulin resistance and dyslipidemia did not prove to be higher among affluent city dwellers. Women were particularly affected by abdominal obesity, at 48% compared to 6% of men. Protective factors against the risk of NRCD were physical activity and adequate micronutrient intake. The research also showed that nutritional deficiencies were not restricted to schoolchildren in rural areas because in the capital of Ouagadougou, for example, 40% of schoolchildren were anaemic and 40% were vitamin A deficient. Partnership research has expanded to include advocacy and human resources training. Conclusion These initial studies on NRCD in West Africa indicate the relevance and urgency of prevention, even among low-income groups and countries. They show that the fight against NRCD as well as nutritional deficiencies should focus on women. Seeing how researchers from the African partner institutions have connections with decision-making authorities, the research findings could have an impact on prevention policies and programs in communities and schools alike. Greater support must nevertheless be provided to lobbying and advocacy work for an even greater impact. As well, the sustainability of the research program remains a challenge that requires resource mobilization and training for the purpose.</p
