[Epidemiology of dementia in elderly living in the 3rd borough of Bangui (Central African Republic)]. / Épidémiologie des démences chez les personnes âgées dans le troisième arrondissement de la ville de Bangui (République Centrafricaine).

Given the gradual improvement of living conditions and aging, dementia and related syndromes are becoming serious problems in the developing countries. A cross-sectional door to door type study in neighbourhood, was conducted from October 2008 to January 2009, in the general population in Bangui, order to help get a better understanding of the prevalence and risk factors of dementia among people over 65 living in the Central African capital. Of the 496 elderly respondents, 188 had cognitive disorders. After a neuropsychological examination, 40 of these subjects were diagnosed with dementia. The prevalence of dementia was 8.1% (IC 95% = [5.7-10.5]). The average age of subjects with dementia, ranging from 65 to 90 years, was 76.0 ± 7.1 years. There was a significant risk of developing dementia for an increase of ten years old (OR = 2.6, 95% CI [1.5 to 4.5]). The sex-ratio was 6/34. 82.5% of the demented had never attended school. 70.0% showed a state of malnutrition (BMI ≤ 18,5 kg/m(2)), significantly associated with dementia (OR = 3.3; IC 95% = [1.5-7.3]). The blood pressure was high in 67.5% of demented which is significantly associated with dementia (OR = 2.4; IC 95% = [1.1-5.4]). A recent change in financial status was a factor significantly associated with dementia (OR = 6.4; IC 95% = [1.8-22.5]). These results support the existence of dementia in urban Africa. The observed prevalence is close to those found in high-income countries. Further studies should be conducted which includes both the rural and urban Africa, to better understand the problem and solutions consider to comprehensive care and prevention axes adapted to our context.

[Assessment of antibiotics prescribing for outpatients in Cotonou, Benin]. / Evaluation de la prescription des antibiotiques en médecine ambulatoire à Cotonou, Bénin.

The objective was to study antibiotics prescribing in Cotonou health care centres. This prospective study was conducted in two phases. The first consisted in collecting antibiotics prescriptions. In a second phase, the prescriptions were submitted to 4 experts who assessed the correctness of the prescribing. Out of the 588 prescriptions that could be analysed, 173 (29.4%) were correct The quality of the prescribing seems to depend only on the pathology but not on the nature of the basic training of the prescriber

[Underweight prevention and treatment of the young child in Mono (Benin)]. / Prévention et traitement de l'insuffisance pondérale chez le jeune enfant du Mono (Bénin).

BACKGROUND: This study aimed to assess the prevention and treatment effectiveness of underweight in less than two years old children admitted in 2001 to community nutrition programme of Mono area in Benin. METHODS: A longitudinal retrospective survey took place in 30 villages chosen at random. It concerned a sample of 1799 children. Inside of those children, during the 2001 year, when they were admitted to the programme, 1545 were without underweight, have had more than one month following visit and about them the underweight effectiveness prevention had been analyzed; the others 111 were underweighted, have had more than one month following visit and about them the underweight treatment had been assessed. The 143 other children have been followed for only one month. The prevention effectiveness had been explored by the evolution of the cumulative incidence of underweight according to the number of following visit and the underweight incidence density. The treatment effectiveness has been analysed by calculating the recovery rate and incidence density. RESULTS: During 2001, there have been observed 10% for the underweight cumulative incidence and 51.4% for the cumulative incidence of underweight recovery. The underweight and recovery incidence density were respectively 14 cases for 1000 persons-months of following and 118 cases for 1000 persons-months of following. The children with serious underweight at their last following visit have had the number of following visits lower than those who were with moderate underweight. The recovery was arrived after two to twelve months. There was a significant increase of underweight prevalence with the increase of following visit number inside the children with a normal weight at their admission into the programme. CONCLUSION: During the 2001 following, the underweight prevention and treatment activities of community nutrition workers have been little effectiveness. The low level of instruction of community nutrition workers, their low level of knowledge of essential community nutrition activities, their multiple tasks and the not used appropriate foods for the treatment of underweight are the possible causes of the poor performance observed.
