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.

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.

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 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.

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.
