Dementia and Geriatric Cognitive Disorders | Year: 2010
Background: Data on dementia from low-and middle-income countries are still necessary to quantify the burden of this condition. This multicenter cross-sectional study aimed at estimating the prevalence of dementia in 2 large cities of Central Africa. Methods: General population door-to-door surveys were conducted in the districts of Bangui (Republic of Central Africa) and Brazzaville (Congo) in elderly aged ≥65 years. The subjects were screened with the Community Screening Interview for Dementia and the Five-Words Test. Diagnosis of dementia was made according to the DSM-IV criteria and to the clinical criteria proposed by the NINCDS-ADRDA for Alzheimer's disease. Results: We enrolled 496 subjects in Bangui and 520 in Brazzaville. The prevalence of dementia was estimated at 8.1% (95% CI = 5.8-10.8) in Bangui and 6.7% (95% CI = 4.7-9.2) in Brazzaville. Conclusion: The prevalence of dementia in urban areas of Central Africa is close to those observed in high-income countries. © 2010 S. Karger AG, Basel.

Neuroepidemiology | Year: 2010
Background: Our aim was to validate the use of historical events as tools for estimating the age of people ≥65 years in Cotonou (Benin). Methods: The survey was conducted in Cotonou, the economic capital of Benin. We included people aged ≥65 years, with at least a primary education level and an administrative document certifying their date of birth. The historical events were the solar eclipse of 1946 covering the national territory and the date of independence (1st August 1960) of Dahomey (Benin). Agreement between estimated and actual age was assessed by the intraclass correlation coefficient and the Bland and Altman graphical representation. Results: We included 112 subjects. The intraclass correlation coefficient between actual and estimated age by the use of historical landmarks was 0.87 (95% CI = 0.81-0.91), i.e. an excellent concordance. The graph of Bland and Altman did not demonstrate any systematic error of estimation. Conclusion: The development of similar tools in other parts of Africa and developing countries may improve the quality of information collected in epidemiological studies and thereby enhance the accuracy of the results of studies conducted on age-related disorders such as dementia. © 2010 S.

Parasites and Vectors | Year: 2010
Background: Insecticide treated plastic sheeting (ITPS), sometimes known as durable lining, has potential as a long-lasting insecticidal surface for malaria vector control when used as lining for interior walls and ceilings inside the home. Against a backdrop of increasing long lasting net (LN) coverage, we examined the effect of combining permethrin-treated plastic sheeting (ITPS) with LNs in Burkina Faso. Methods: A verandah trap experimental hut trial of ITPS with or without Olyset LN was conducted in the Vallée du Kou near Bobo-Dioulasso, where the two molecular forms of Anopheles gambiae s.s., S (frequency 65%) and M (frequency 35%), occur. The S form is mostly pyrethroid resistant (Fkdr = 92%) owing to the kdr mechanism, and the M form is mostly kdr susceptible (Fkdr = 7%). The treatment arms included ITPS, Olyset, ITPS plus Olyset, ITPS plus untreated net (with or without holes), and untreated control. Results: ITPS was significantly inferior to Olyset LN in terms of mortality (37% vs 63%), blood feeding inhibition (20% vs 81%) and deterrence (0 vs 42%) effects, and hence altogether inferior as a means of personal protection (16% vs 89%). The addition of ITPS to Olyset did not improve mortality (62%), blood feeding inhibition (75%), deterrence (50%) or personal protection (88%) over that of Olyset used alone. Use of untreated nets - both holed and intact - with ITPS provided greater protection from blood-feeding. The intact net/ITPS combination killed more mosquitoes than ITPS on its own. Conclusions: Although ITPS has a potential role for community control of malaria, at low coverage it is unlikely to be as good as Olyset LNs for household protection. The combination of pyrethroid IRS and pyrethroid LN - as practiced in some countries - is unlikely to be additive except, perhaps, at high levels of IRS coverage. A combination of LN and ITPS treated with an alternative insecticide is likely to be more effective, particularly in areas of pyrethroid resistance. © 2010 Chandre et al; licensee BioMed Central Ltd.

The goals of this cross-sectional study conducted in the Zè district of Benin were to determine the overall distribution and prevalence of Buruli ulcer (BU) identify environmental and behavioral risk factors. A total of 425 current or previous BU patients from the study district were included. Data was obtained by direct observation, semi-structured interviews, and document review. The main findings can be summarized as follows. The overall prevalence of BU in the Zè district in 2006 was 52 cases per 10000 inhabitants. The prevalence of current and previous cases was 28.1 and 23.9 per 10000 inhabitants respectively. The distribution of BU within the district was highly variable from one subdistrict to another and from one village toanother within the same subdistrict. The subdistricts showing the highest and lowest endemicity were Djigbé with 265 cases per 10 000 inhabitans and Koundokpoé with 3 cases per 10 000 inhabitants respectively. Proximity of the hamlets to water bodies was a risk factor for the disease.

Background: Free tuberculosis control fail to protect patients from substantial medical and non-medical expenditure, thus a greater degree of disaggregation of patient cost is needed to fully capture their context and inform policymaking. Methods: A retrospective cross-sectional study was conducted on a convenience sample of six health districts of Southern Benin. From August 2008 to February 2009, we recruited all smear-positive pulmonary tuberculosis patients treated under the national strategy in the selected districts. Direct out-of-pocket costs associated with tuberculosis, time delays, and care-seeking pattern were collected from symptom onset to end of treatment. Results: Population description and outcome data were reported for 245 patients of whom 153 completed their care pathway. For them, the median overall direct cost was USD 183 per patient. Payments to traditional healers, self-medication drugs, travel, and food expenditures contributed largely to this cost burden. Patient, provider, and treatment delays were also reported. Pre-diagnosis and intensive treatment stages were the most critical stages, with median expenditure of USD 43 per patient and accounting for 38% and 29% of the overall direct cost, respectively. However, financial barriers differed depending on whether the patient lived in urban or rural areas. Conclusions: This study delivers new evidence about bottlenecks encountered during the TB care pathway. Financial barriers to accessing the free-of-charge tuberculosis control strategy in Benin remain substantial for low-income households. Irregular time delays and hidden costs, often generated by multiple visits to various care providers, impair appropriate patient pathways. Particular attention should be paid to pre-diagnosis and intensive treatment. Cost assessment and combined targeted interventions embodied by a patient-centered approach on the specific critical stages would likely deliver better program outcomes. © 2014 Laokri et al.

Hepatitis B is a major public health problem in Africa. The estimated prevalence in Benin is between 5.2% and 8.3%. Since 1992, the WHO has recommended immunization of all children between 0 and 12 months old all around the world. Benin has been vaccinating children from 0 to 11 months since 1999. The purpose of this study was to identify factors influencing hepatitis B immunization coverage in children from 1 to 8 years old in the Ouidah health district. This descriptive and analytical cross sectional study was carried out from October 25 to 31, 2007. The primary study targets were children from 1 to 8 years. Secondary targets were mothers and healthcare workers. A three-degree cluster sampling technique was used. Hepatitis immunization coverage was 72.2% (95 %CI, 65.4-78.3). The negative factor influencing coverage in children was age over 5 years reflecting the absence of catch-up sessions for untargeted children overlooked for hepatitis B immunization. The negative factor in mothers was age over 30 years pending multivariate analysis that was not performed in this study. Regarding healthcare workers, understating was noted at this level of the health system. Hepatitis B immunization coverage in untargeted children was lower than in children between 0 and 11 months. In 2007, hepatitis B immunization coverage in the Ouidah health district was lower in untargeted children than children of 0 to 11 months. This study showed that immunization coverage decreased with age, thus underlining the need for catch-up sessions to ensure hepatitis B immunization in high prevalence areas.

The burden of chronic and neuropathic pain is high making it an important public health problem. The epidemiology is not well known in the general population in sub-Saharan Africa. We aimed to determine the prevalence of chronic pain with a neuropathic component at Tititou in Parakou in northeastern Benin. A cross-sectional study was conducted from 1st April to 31 May 2012 and included 2314 people in a door-to-door survey. Chronic pain was defined as pain occurring for more than three months. Neuropathic pain was assessed with the DN4 score. A neurological exam was performed by a young physician for all people with chronic pain. During the interview, sociodemographic data, past medical history, weight and height were recorded. Multivariate logistic regression was performed to analyze the main associated factors. Among the 2314 people included in this survey, 49.7% were male. The mean age was 32.3±13.1years. Nine hundred seven reported pain occurring for more than 3months. The prevalence of chronic pain was 39.2% (CI95%: 29.3-34.7). It was more frequent in females, older people, among diabetics, people with a history of any surgery, stroke, brain trauma, and alcoholism. The prevalence of chronic pain with a neuropathic component was 6.3% (CI95%: 5.0-7.9). The main associated factors were age, matrimonial status, professional occupation, body mass index, diabetes, history of zoster, history of any surgery, brain trauma. People with neuropathic pain often reported pain with burning (87.6%), prickling (82.8%), numbness (66.9%), tingling (63.4%), and lightning pain (48.3%). The main locations were the lower limbs and low back pain. This study suggested the high frequency of chronic neuropathic pain in the general population in Parakou compared with rates reported in western countries. © 2014 Elsevier Masson SAS.

Public Health Nutrition | Year: 2014
Objective Food guides are important tools for nutrition education. While developing a food guide in Benin, the objective was to determine the daily number of servings per food group and the portion sizes of common foods to be recommended. Design Linear programming (LP) was used to determine, for each predefined food group, the optimal number and size of servings of commonly consumed foods. Two types of constraints were introduced into the LP models: (i) WHO/FAO Recommended Nutrient Intakes and dietary guidelines for the prevention of chronic diseases; and (ii) dietary patterns based on local food consumption data recently collected in southern Benin in 541 adults. Dietary intakes of the upper tertile of participants for diet quality based on prevention and micronutrient adequacy scores were used in the LP algorithms. Setting Southern area of the Republic of Benin. Subjects Local key-players in nutrition (n 30) from the government, academic institutions, international organizations and civil society were partners in the development of the food guide directed at the population. Results The number of servings per food group and the portion size for eight age-sex groups were determined. For four limiting micronutrients (Fe, Ca, folate and Zn), local diets could be optimized to meet only 70 % of the Recommended Nutrient Intakes, not 100 %. Conclusions It was possible to determine the daily number of servings and the portion sizes of common foods that can be recommended in Benin with the help of LP to optimize local diets, although Recommended Nutrient Intakes were not fully met for a few critical micronutrients. © 2014 The Authors.

Introduction: Work engagement, an emerging concept in the field of positive psychology in the workplace is not well known in developing countries. Defined as a positive and fulfilling mindset related to work, it recalls a positive attitude incentive of performance and need to be investigated. In the context of the socioeconomic crisis of health workers, and with the chronic issue of poor quality of data, this study was designed to identify the factors associated with work engagement among health workers in charge of data collection in the Benin Routine Health Information System. methods: This study was a cross-sectional and analytical study targeting health workers in charge of data collection in public and private health centres. The dependent variable was work engagement and independent variables were sociodemographic and professional features, personal and professional resources and perception of technical factors. Logistic regression was used. The adequacy of the model was tested with the Hosmer-Lemeshow goodness of fit test. results: The results indicate that the level of work engagement is similar with that observed in previous studies. Predictors identified in logistic regression are perception of technical factors, location of the job, and personal resources, such as level of effort and overcommitment. discussion: This study identified factors associated with work engagement in a developing country, and adds to the knowledge concerning this new concept in Benin. The findings can contribute to research for improvement of human resources management in the health sector to achieve real performance and development. © S.F.S.P..

Objective: In developing countries, the poor quality of data derived from Health Information Systems constitutes a problem that limits use of these data and contributes to the recurrent difficulties of health system management. The low level of involvement of health workers directly responsible for data may contribute to this poor quality. This study documents a Health Information System collection tool design experience by health workers and assesses its effect on data quality. Methods: Eighty health workers responsible for clinical statistics in public health centres participated in this study. The two tools used for clinical data collection were modified by a group of 6 volunteer health workers. Monitoring indicators, data entry time, percentage exhaustiveness and quality of data were assessed before and after using the new tools. Data were compared by Wilcoxon's test for paired data and Mc Nemar's chi-square test. Results: Between the two assessments, the data entry time increased from 28.7 to 22.5 seconds by reported case (p = 0.153), the exhaustiveness of the reports increased from 16% to 89% (p < 0.001) and the proportion of reports with sufficient data quality increased from 18.8% to 45.8% (p = 0.002). Conclusion: The positive course of the indicators shows that increased involvement of health workers in key stages such asthe design of data collection tools can help improve data quality. © S.F.S.P..
