| 2 | Prevalence of diarrhoea and risk factors among children under five years old in Mbour,Senegal:a cross-sectional study显示文摘Background:Diarrhoeal diseases remain an important cause of mortality and morbidity among children,particularly in low-and middle-income countries.In Senegal,diarrhoea is responsible for 15%of all deaths in children under the age of five and is the third leading cause of childhood deaths.For targeted planning and implementation of prevention strategies,a context-specific understanding of the determinants of diarrhoeal diseases is needed.The aim of this study was to identify risk factors of diarrhoeal diseases in children under the age of five in Mbour,Senegal.Methods:Between February and March 2014,a cross-sectional survey was conducted in four zones of Mbour to estimate the burden of diarrhoeal diseases(i.e.diarrhoea episodes in the 2 weeks preceding the survey)and associated risk factors.The zones covered urban central,peri-central,north peripheral and south peripheral areas.Overall,596 households were surveyed by a questionnaire,yielding information on sociodemographic,environmental and hygiene behavioural factors.Univariable and multivariable logistic regression analyses were used to identify risk factors associated with the occurrence of diarrhoea.Results:The reported prevalence of diarrhoea among children under the age of five during the 2 weeks preceding the survey was 26%.Without adjustment,the highest diarrhoea prevalence rates were observed in the peri-central(44.8%)and urban central zones(36.3%).Multivariable regression revealed significant associations between diarrhoeal diseases and unemployment of mothers(adjusted odds ratio[aOR]=1.62,95%confidence interval[CI]:1.18-2.23),use of open bags for storing household waste(aOR=1.75,95%CI:1.00-3.02),evacuation of household waste in public streets(aOR=2.07,95%CI:1.20-3.55),no treatment of stored drinking water(aOR=1.69,95%CI:1.11-2.56)and use of shared toilets(aOR=1.69,95%CI:1.11-2.56).Conclusion:We found a high prevalence of diarrhoea in children under the age of five in Mbour,with the highest prevalence occurring in the central and peri-central areas.These findings underscore the need for public health interventions to alleviate the burden of diarrhoea among vulnerable groups.Promotion of solid waste disposal and reduction of wastewater exposure should be implemented without delay. | Sokhna Thiam Aminata N.Diene Samuel Fuhrimann Mirko S.Winkler Ibrahima Sy Jacques A.Ndione Christian Schindler Penelope Vounatsou Jurg Utzinger Ousmane Faye Gueladio Cisse | 2017 | Infectious Diseases of Poverty2017，6，1： | 1 |
| 3 | Risk factors for schistosomiasis in an urban area in northern Cote d’Ivoire显示文摘Background:Schistosomiasis is a water-based disease transmitted by trematodes belonging to the genus Schistosoma.The aim of this study was to assess the relationship between the prevalence of schistosomiasis and access to water,sanitation and hygiene(WASH)and environmental and socioeconomic factors in the city of Korhogo,northern Côte d'Ivoire.Methods:A cross-sectional study including 728 randomly selected households was conducted in Korhogo in March 2015.The heads of the households were interviewed about access to WASH and environmental and socioeconomic factors.All children abed between 5 and 15 years living in the households were selected to provide stool and urine samples for parasitological diagnosis of Schistosoma mansoni and Schistosoma haematobium infection.The relationship between infection with S.mansoni and potential risk factors was analysed by a mixed logistic regression model with‘household’as a random factor.Likelihood ratio tests were used to identify factors that were significantly associated with a Schistosoma spp.infection.Results:The overall prevalence of schistosomiasis among school-aged children in Korhogo was 1.9%(45/2341)composed of 0.3%(3/1248)S.haematobium and 3.5%(42/1202)S.mansoni.Due to the low prevalence of S.haematobium infection,risk factor analysis was limited to S.mansoni.Boys were 7.8 times more likely to be infected with S.mansoni than girls.Children between 10 and 15 years of age were 3.8 times more likely to be infected than their younger counterparts aged 5-10 years.Moreover,living in a house further away from a water access point(odds ratio[OR]=0.29,95%confidence interval[CI]:0.13-0.70)and abstaining from swimming in open freshwater bodies(OR=0.16,95%CI:0.04-0.56)were significantly associated with decreased odds of S.mansoni infection.The socioeconomic status did not appear to influence the prevalence of S.mansoni.Conclusions:A strategy to reduce the incidence of schistosomiasis should focus on health education to change the behaviour of populations at risk and encourage communities to improve sanitation and infrastructure in order to reduce contact with surface water. | Richard K.M’Bra Brama Kone Yapi G.Yapi Kigbafori D.Silue Ibrahima Sy Danielle Vienneau Nagnin Soro Gueladio Cisse Jurg Utzinger | 2018 | Infectious Diseases of Poverty2018，7，1： | 0 |
