    ABSTRACT: Contraceptive prevalence is low in Senegal, particularly in the Mbacké health district. The objective of this study was to identify the determinants of use of modern contraception by women of reproductive age in this district. A quantitative and qualitative analytical study was conducted. The quantitative survey was conducted from 1st to 20 July 2011. The study population consisted of women of childbearing age living in the district. A two-stage survey was conducted. Data were entered and bivariate analysis was performed using Epi Info 3.3.5software. Multivariate analysiswas performed by R 2.2.9 software. The adjusted odds ratios were calculatedfor variables with significant p values. The qualitative study was conducted from 25 to 31 July2011. Grouped interviews were used to collect women's perceptions of modern contraception. Content analysis was performed. Improving the socio-economic characteristics of women and raising public awareness about modern contraception would contribute to a better use of modern contraceptives in the Mbacké health district.

    ABSTRACT: Malnutrition is an important indicator of development, and its consequences in children and adolescents produce a serious socioeconomic burden. Children living on the street are more vulnerable than others. Thus, our objective was to analyze the nutritional status of children living on the streets of Manga, through a cross-sectional and analytical study. The snowball technique was used for sampling. Data came from individual interviews, blood samples and medical examinations. Of the 237 children studied, 84.8% were boys; the overall mean age was 11.5 years, and 72.6% were adolescents (aged 10 to 17 years). Growth retardation (15.9%) predominated among the children aged 4 to 9 years, while a weight deficit (27.9%) was most common among those aged 10 to 17. Half of the children (50.2%) with blood tests (N = 119) had anemia. There was a link between anemia and underweight (p = 0.0145). Children who ate at least three times a day were 2.63 times less likely to be anemic (p<0.001). Factors associated with anemia (p<0.005) included survival activities. We frequently found nutritional deficits and anemia in these children. A targeted nutritional program would be a good entry point for their successful reintegration..

    ABSTRACT: Introduction: The objective of this study was to investigate the determinants of rape among minors in the Kolda region. Methodology: A retrospective, cross-sectional, descriptive and analytical was conducted from 23 December 1992 to 31 December 2011, based on the charts of rape victims under the age of 18 years. Sampling was complete. Bivariate and multivariate analyses were performed using Epi Info 3.3.2 and R 2.9.2 software, respectively. Results: The study included 162 cases of sexual assault. The mean age of victims was 12.3 +/- 3 years (range: 4-17 years). The mean age of perpetrators of sexual assault was 26.4 +/- 9.5 years and minors accounted for 13% of perpetrators. 54.9% of victims, were raped. Victims of sexual assault knew the perpetrator in 66% of cases and were attacked in broad daylight in 53.4% of cases. The perpetrators were drunk at the time of sexual assault in 15.3% of cases. The assault took place in the bush (14.8%). Twenty eight percent (28%) of rapists were jailed and 38.6% of them were jailed for between 5 and 10 years. Sexual assault in the bush [adjusted OR = 3.46 (1.02-11.77)] and intoxication of the perpetrator at the time of sexual assault [adjusted OR = 3.47 (1.04-11.61)] were associated with a high risk of rape. In contrast, victims who knew their assailants were at a lower risk of rape [adjusted OR = 0.09 (0.03 to 0.24)]. Conclusion: Extension of this study to the national scale would provide health and judicial authorities with an overview of sexual assault among minors, to allow more effective prevention at the national level.

    ABSTRACT: /st>To evaluate the reliability of direct observation for measuring intrapartum care and compare this method with clinical audits using objective criteria based on patients' medical charts. /st>Cross-sectional study, data collected by two independent evaluators. /st>Hospital in Dakar, Senegal. /st>Thirty consecutive intrapartum care episodes provided by midwives and the corresponding medical charts.Outcome MeasureThe presence or absence of each of twelve criteria selected on the basis of national and international norms for monitoring of labour and delivery (six criteria) and the immediate postpartum period (six criteria). /st>For direct observation, the labour and delivery mean quality scores ranged from 5.34 to 5.77. In contrast, for the chart-based method, the scores ranged from 0.32 to 0.45. For postpartum care evaluated only with direct observation, the scores were also high (5.21-5.65). For direct observation, inter-evaluator agreement was high: kappa coefficients varied from 0.78 to 0.93 depending on the criterion (total score ICC = 0.74). For the chart-based method, inter-evaluator agreement was also high: 0.66 to 1 (total score ICC = 0.72). Comparison of the two methods showed strong differences by items and subscores. /st>Using direct observation, the quality of obstetric care was high for both the monitoring of labour and delivery and postpartum care. Both measurement instruments showed high reliability. The chart-based method underestimated the quality of care because of poor medical record documentation. Medical-record-based measurement may not be appropriate for the evaluation of the quality of obstetric care in Senegal and other low-income settings.

    ABSTRACT: In Senegal, a significant decrease in catches indicates that many demersal fish stocks are being overexploited. The white grouper Epinephelus aeneus, locally known as the ‘thiof’, is exploited by both small-scale and industrial fisheries. A 28-year database of E. aeneus catches along the Senegalese coast provided by the Centre for Oceanographic Research of Dakar-Thiaroye, and size at maturity measured in Dakar (Senegal) from monthly samples in 2010, were used to analyse changes in population structure in the area over the past 37 years. Catches from the northern fishing areas were lower than those from the southern fishing areas, and decreased steadily during the period (Kolmogorov–Smirnov test, D = 0.243, p = 0.0002). The individual mean weight of catches decreased from 1974 to 2010 (linear regression, r 2 = 0.40, n = 37) and only 60% of the individuals were mature. The calculated sizes at maturity were 49 cm total length (TL) for females and 55 cm for males, and the optimal length of capture for a sustainable fishery was 96 cm, but only 0.03% of E. aeneus caught reached this length. Most of the catch consisted of juveniles; the larger reproductive individuals had disappeared. The number of individuals caught decreased significantly between 1974 and 2010 (1974–1983, r 2 = 0.98, n = 74 674; 1984–1993, r 2 = 0.95, n = 96 696; 1994–2003, r 2 = 0.93, n = 12 619; 2004–2010, r 2 = 0.91, n = 12 887), whereas the length range remained the same (10–110 cm TL). Biological indicators clearly showed that E. aeneus stocks in Senegal are overexploited and the species is now endangered. Immediate active management of fishing pressure is needed, therefore, to maintain E. aeneus populations in the area. Our results suggest a minimum size of <50 cm should be introduced and that fishing effort should be reduced.

    ABSTRACT: Introduction: As throughout sub-Saharan Africa, the use of skin-lightening (or brightening or bleaching) products is widespread in Senegal (67%). Although the medical and social determinants of this phenomenon have been documented, its cost is poorly defined. Thus, this work aims to evaluate the economic effects of skin bleaching on women's income. Methodology: A cross-sectional, quantitative, and descriptive survey was conducted in 2010 (October 7 to November 8) among women consulting for outpatient care at a reference dermatology clinic for complications related to use of skin-lightening products. We calculated the direct costs (products) and indirect costs (transportation costs, medical fees, dermatological treatment of complications). The social damage (pain and suffering and esthetics) was assessed. Results: This study included 65 women; their mean age was 33 years and 26% had not attended school. In all, 52% were merchants, 29% housewives, 9% civil servants, and 5% students. The average duration of product use was 9 years, and the mean age at onset of use, 23 years. Most (80%) had a low income (<100,000 FCFA or US $204). The total monthly income of the 65 women in the study was 5,675,000 CFA (US $ 11,582). The total monthly cost of skin lightening for them was 1081,658 CFA (US $ 2207), that is, 19% of their total income. The esthetic harm was categorized as moderate by 20% and high by 22%. Conclusion: This study opens perspectives for further studies of the intangible costs of skin bleaching and for increasing awareness of the complications and social damage induced.

    ABSTRACT: As a way to prevent maternal mortality and stillbirth, the dystocia risk score includes three components: a left column provides a list of eight characteristics to check for in the woman; an upper horizontal section provides a checklist of possible outcomes of the pregnancy itself: and a rectangular grid indicates the prognosis in three zones: a large red (dangerous), a medium-sized grey (doubtful) and a small blue (hopeful). The DRS is positive if there is at least one cross in the dangerous zone and/or two crosses in the doubtful zone (it indicates that the woman should be referred to a center specialized in obstetric emergency care); elsewhere, the DRS is negative. The validation test gives good results (sensitivity=83.61%, specificity=90.05%, positive predictive value=72.34%, and negative predictive value=94.04%). Its large-scale use would accelerate the identification of pregnant women with a high risk of dystocia. Their timely referral to specialized emergency obstetrics centers would increase the efficacy of care and reduce the levels of maternal mortality and stillbirth.

    ABSTRACT: Access to health care remains a major problem in Senegal, particularly among vulnerable groups such as the elderly. In 2006, the Senegalese government introduced a national plan for the provision of free health care known as "Plan Sésame" to improve access to care. The purpose of this study was to examine the current state of the "Plan Sésame" in national hospitals four years after its implementation (2006-2009). A qualitative study using individual interviews was conducted between 15 March and 14 May 2010 among five target populations: hospital directors, health care providers, managers of the "Plan Sésame" in hospital admission services, management accountants, and beneficiaries. Content analysis was used. Between 2006 and 2008, hospital attendance rates increased every year. However, attendance rates began to decrease in 2009, except in the main hospital. The state has been left with a growing debt because of issues surrounding the reimbursement of expenses related to the "Plan Sésame'. As a result, national hospitals have been forced to restrict certain services included in the "Plan Sésame" and even to withdraw free health care for the elderly. These difficulties are likely to undermine the sustainability of the "Plan Sésame" The health authorities need to audit the "Plan Sésame:, to comply with standard procedures through regular monitoring and to redefine conditions of access.

    ABSTRACT: Au Sénégal, la distribution gratuite de médicaments lors des consultations prénatales est préconisée pour supprimer les disparités. L’objectif de cette étude est d’étudier les facteurs influençant l’accès au traitement dans une situation de gratuité. Il s’agit d’une étude transversale et analytique portant sur un échantillon de 1 906 femmes âgées de 15 à 49 ans tiré au sort lors de l’enquête nationale sur le paludisme au Sénégal. Les données ont été collectées lors d’un entretien individuel. Le bien-être économique était mesuré à partir des caractéristiques du logement et des biens durables. L’analyse multivariée a été réalisée à l’aide d’une régression logistique. La moyenne d’âge des femmes était de 27,9 ± 5,34; 64,3 % résidaient en milieu rural; 71,8 % des femmes n’avaient reçu aucune instruction. Parmi les femmes étudiées, 23 % étaient dans le quintile le plus pauvre tandis que 16,3 % étaient dans le plus riche. Le traitement préventif intermittent (TPI) était effectué dans 49,3 % des cas. Le TPI était plus souvent réalisé en milieu urbain (OR: 1,45; IC 95 %: [1,17–1,72]). Il augmentait avec le niveau d’instruction avec un OR à 1,5 au primaire et 1,68 au secondaire et plus. La réalisation du TPI augmentait avec le bien-être économique. L’OR variait de 1,44 au deuxième quintile à 2,95 pour les plus riches. La gratuité ne profite pas souvent aux plus pauvres. D’autres mesures d’accompagnement devront être développées pour faciliter la distribution des médicaments particulièrement au niveau communautaire avec l’implication des populations.

    ABSTRACT: In 2009, the region of Dakar (Senegal) experienced a major measles epidemic, in the context of the failure of the immunization program. The objective of this study was to examine the epidemic and the effectiveness of the response. A cross-sectional epidemiological study of all cases of measles confirmed by laboratory tests or epidemiological linkage was conducted between June and December 2009. The study also assessed the effectiveness of the response. The results show that out of 767 confirmed cases, less than a third (30 %) were laboratory-confirmed, while the remaining cases were confirmed by epidemiological linkage with one or several other confirmed cases. The minimum age was 4 months and the maximum age was 35 years. Children under 5 accounted for 67.4 % of the total number of cases. The male population was more affected than the female population (52.2 %). Most of the cases of were not vaccinated (88.5 %). The southern district had the highest incidence of measles, with more than 68 cases per 100,000 inhabitants. The vaccination coverage rate over the last 3 years was found to be satisfactory (average rate: 82.2 %). The response campaign resulted in the vaccination of 54,793 children aged 9 to 59 months (55.9%) distributed throughout the high-risk areas with low immunization coverage. No deaths were reported. The results suggest that it is important i) to continue to promote measles vaccination; ii) to combine routine vaccinations with supplements (for example vitamin A); iii) to introduce national vaccination campaigns targeting specific groups (new army recruits, students, refugees, etc.); and iv) to introduce a second dose of vaccine to ensure that the children who did not receive the first vaccine are covered and to address primary vaccine failures among those who were vaccinated.

    ABSTRACT: The objective of this study was to examine the socio-demographic profile and treatment of women suffering from obstetric fistula (OF) in southeastern Senegal. Conducted between August 2007 and January 2008, the study focused on women treated in regional hospitals in Tambacounda and Kolda. The data were collected using questionnaire-based interviews and analyzed using the Epi Info 3.3.1 software package. The patients (mean age of occurrence of OF: 24) were mostly from rural areas (86%), illiterate (89%), and excised (93%). The main cause of the condition cited by the participants was long working hours (42%). The study found that the participants were more likely to have no income-generating activity (84% compared to 22%) and to be divorced (19% compared to 2%) after (as opposed to before) the OF. The study also highlighted the prevalence of psychological disorders (62%), withdrawal (22%), abandonment by friends and/or family (16%) or by the husband (7%), and decreased effectiveness in household chores (4%). The average time between the occurrence of OF and the first consultation was 50.7 (± 55.3) months. The study found that 44% of the participants were waiting for an operation, 35% had undergone unsuccessful surgery, 14% had been treated and cured, 6% had recently undergone surgery, and 1% had suffered a recurrence. Good access to services was found to be necessary for effective treatment, although high-quality obstetric care and increased awareness were identified as the most important factors for the prevention of OF in southeastern Senegal.

    ABSTRACT: The study highlights the potential of the black-chinned tilapia to be used as a sentinel to assess environmental contaminants based on the use of a set of biomarkers. The usefulness of fish species as sentinels for assessing aquatic environment contamination was tested using a set of biomarkers in Senegalese environments characterized by multi-pollution sources. The black-chinned tilapia (Sarotherodon melanotheron) was selected as a sentinel because of its abundance, wide distribution in all coastal aquatic ecosystems and physiological properties. The potential influence of confounding factors such as salinity on biomarker in the tilapia has been examined. Individuals were sampled during two seasons (dry and wet) in eight sites characterized by various degrees of anthropogenic contamination and different salinities (from 0 to 102 psu). Biomarkers-including growth rate (GR), condition factor (CF), biotransformation enzymes such as 7-ethoxyresorufin-O-deethylase (EROD) and glutathione-S-transferase (GST), lipid peroxidation (TBARS) and acetylcholinesterase (AChE)-were measured. Chemical contaminant [polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs)] levels showed different sources of contamination with relatively high concentrations of PAHs in the Hann Bay and Foundiougne locations. The most sensitive biomarker present in different sites according to the principal component analysis is EROD. Few variations of the AChE activity and TBARS levels were found. No clear relationship was found between biomarker responses and salinity, but GR and CF were lower in hypersaline conditions. Tilapia is responsive to environmental contaminants such as PAHs, OCPs and PCBs. The S. melanotheron multiparametric approach showed a better discrimination of sites.
