An evaluation of a national oral rehydration solution and zinc scale-up program in Kenya between 2011 and 2016

Factors associated with the co-utilization of oral rehydration solution and zinc for treating diarrhea among under-five children in 35 sub-saharan Africa countries: a generalized linear mixed effect modeling with robust error variance

INTRODUCTION

Even though childhood diarrhea is treated with a simple treatment solution, it continues to be one of the leading causes of under-five child mortality and malnutrition globally. In resource-limited settings such as Sub-Saharan Africa (SSA), the combination of oral rehydration salts (ORS) and zinc is regarded as an effective treatment for diarrhea; however, its utilization is very low. The purpose of this study was to determine the proportion and associated factors of co-utilization of ORS and zinc among under-five children with diarrhea in SSA.

METHODS

The proportion and associated factors of co-utilization of ORS and zinc among under-five children with diarrhea in SSA were determined using secondary data analysis of recent Demographic and Health Surveys (DHS) of 35 SSA countries. The study included a total of 44,341 under-five children with diarrhea in weighted samples. A generalized linear mixed-effects model with robust error variance was used. For the variables included in the final model, adjusted prevalence ratios (aPR) with 95% confidence intervals (CI) were estimated. A model with the lowest deviance value were considered as the best-fitted model.

RESULT

The pooled proportion of co-utilization of ORS and zinc for the treatment of diarrhea among under five children in SSA countries was 43.58% with a 95% CI (43.15%, 44.01%). Sex of the child, maternal age, residence, maternal educational and employment status, wealth index, media exposure, perceived distance to health facility and insurance coverage were statistically significant determinants of ORS and Zinc co-utilization for treating diarrhea among under five children in SSA.

CONCLUSION

Only less than half of under-five children with diarrhea in SSA were treated with a combination of ORS and zinc. Thus, strengthening information dissemination through mass media, and community-level health education programs are important to scale up the utilization of the recommended combination treatment. Furthermore, increasing health insurance coverage, and establishing strategies to address the community with difficulty in accessing health facilities is also crucial in improving the use of the treatment.

Coutilisation of oral rehydration solution and zinc for treating diarrhoea and its associated factors among under-five children in East Africa: a multilevel robust Poisson regression

OBJECTIVE

This study aimed to assess the coutilisation of oral rehydration solution (ORS) and zinc for treating diarrhoea and its associated factors among under-5 children in East Africa.

DESIGN

Cross-sectional study design. Multilevel Poisson regression analysis with robust variance was fitted to identify predictors of zinc and ORS coutilisation. An adjusted prevalence ratio (aPR) with a 95% CI was reported to declare the statistical significance.

SETTING

Twelve East African countries.

PARTICIPANTS

16 850 under-5 children who had diarrhoea were included in the study.

RESULT

In East African nations, the coutilisation of ORS and zinc for the treatment of diarrhoea in children under 5 was 53.27% with a 95% CI (52.54% to 54.01%). Children of mothers with primary education (aPR 1.15, 95% CI 1.09 to 1.20), secondary education (aPR 1.08, 95% CI 1.02 to 1.14), higer education (aPR 1.19, 95% CI 1.10 to 1.29), those from maternal age category of 20-24 (aPR 1.14, 95% CI 1.07 to 1.21), age category of 25-29 (aPR 1.13, 95% CI 1.06 to 1.21), age category of 30-34 (aPR 1.09, 95% CI 1.02 to 1.16), those from wealthy households (aPR 1.04, 95% CI 1.01 to 1.09) and those who have a media exposure (aPR 1.04, 95% CI 1.01 to 1.08) were more likely to receive combination.

CONCLUSION

Only half of the under-5 children with diarrhoea in East Africa were treated with a combination of ORS and zinc. To increase the use of the suggested combination therapy of ORS with zinc, it is important to empower women through education and prevent teen pregnancy.

Access to oral rehydration solution and zinc supplementation for treatment of childhood diarrhoeal diseases in Sudan

Objectives

The decline in diarrhoeal disease-related mortality globally has been attributed to the use of oral rehydration solution (ORS) and zinc supplementation. However, data on ORS and zinc supplementation in Sudan are scarce. We aimed to investigate the access to ORS and zinc treatments and the associated factors, through the analysis of the latest available data from Sudan-Multiple Indicator Cluster Survey (MICS)-2014 obtained from the United Nations Children’s Fund (UNICEF).

Results

A total of 14,081 children were included in this analysis. During the 2 weeks preceding the survey, 29.3% of these children had a diarrhoeal disease. Only 18.9% and 14.8% of these children had received ORS and zinc supplements, respectively. Whereas children from the higher wealth index groups were more likely to receive ORS treatment (fourth group: AOR = 1.301; 95% CI 1.006–1.682), children from rural areas were less likely to receive ORS treatment (AOR = 0.666; 95% CI 0.552–0.803) and zinc supplements (AOR = 0.603; 95% CI 0.500–0.728). The results indicate the existence of unequal access to treatment of childhood diarrhoeal diseases among children under 5 years in Sudan.

Factors associated with zinc utilization for the management of diarrhea in under-five children in Ethiopia

BACKGROUND

Zinc has a tremendous advantage to save the life of children. It reduces the mean duration of diarrhea and mortality due to diarrhea. Besides, it reduces the severity of the initial episode, and also it prevents future diarrhea episodes. But there is low utilization of zinc for the management of diarrhea in under-five children in Ethiopia and there is a paucity of literature regarding the factors associated with the utilization.

METHOD

The 2016 Ethiopian demographic and health survey data were used as a data source. A total weighted sample of 1228 under-five children with diarrhea within 2 weeks preceding the survey were used. A mixed-effects logistic regression analysis was done to account for the complex sample design of the data. Variables with p-value < 0.20 in the bivariable analysis were eligible for multivariable analysis and those variables with p value< 0.05 in the multivariable analysis were declared to be determinants of zinc utilization for the management of diarrhea in under-five children.

RESULT

In this study, we found multiple determinants of zinc utilization. Mothers with formal education (adjusted odds ratio (AOR) = 1.83;95% CI; 1.30-2.58) and media exposure (AOR = 1.46;95% CI; 1.04-2.04) had higher odds of zinc utilization. But mothers from five and above household size (AOR = 0.57;95% CI; 0.39-0.82) had lower odds of zinc utilization for the management of diarrhea in under-five children.

CONCLUSION

In our study maternal education, media exposure, and household size were determinants of zinc utilization for the management of diarrhea in under-five children. Being having a formal education and being exposed to all or either of the three media (radio, TV, and newspaper) increases the likelihood of zinc utilization while being mothers from large household size decreases the likelihood of zinc utilization. Therefore, giving special attention to those mothers with no formal education, and mothers from high family size could increase the utilization of zinc for the management of diarrhea in under-five children. Also, media campaigns regarding diarrhea management could be scaled up to potentially achieve the desired impact.

A predictive model for healthcare coverage in Yemen

Introduction

The ongoing war in Yemen continues to pose challenges for healthcare coverage in the country especially with regards to critical gaps in information systems needed for planning and delivering health services. Restricted access to social services including safe drinking water and sanitation systems have likely led to an increase in the spread of diarrheal diseases which remains one of greatest sources of mortality in children under 5 years old. To overcome morbidity and mortality from diarrheal diseases among children in the context of severe information shortages, a predictive model is needed to determine the burden of diarrheal disease on Yemeni children and their ability to reach curative health services through an estimate of healthcare coverage. This will allow for national and local health authorities and humanitarian partners to make better informed decisions for planning and providing health care services.

Methods

A probabilistic Markov model was developed based on an analysis of Yemen’s health facilities’ clinical register data provided by UNICEF. The model combines this health system data with environmental and conflict-related factors such as the destruction of infrastructure (roads and health facilities) to fill in gaps in population-level data on the burden of diarrheal diseases on children under five, and the coverage rate of the under-five sick population with treatment services at primary care facilities. The model also provides estimates of the incidence rate, and treatment outcomes including treatment efficacy and mortality rate.

Results

By using alternatives to traditional healthcare data, the model was able to recreate the observed trends in treatment with no significant difference compared to provided validation data. Once validated, the model was used to predict the percent of sick children with diarrhea who were able to reach, and thus receive, treatment services (coverage rate) for 2019 which ranged between an average weekly minimum of 1.73% around the 28th week of the year to a weekly maximum coverage of just over 5% around the new year. These predictions can be translated into policy decisions such as when increased efforts are needed to reach children and what type of service delivery modalities may be the most effective.

Conclusion

The model developed and presented in this manuscript shows a seasonal trend in the spread of diarrheal disease in children under five living in Yemen through a novel incorporation of weather, infrastructure and conflict parameters in the model. Our model also provides new information on the number of children seeking treatment and how this is influenced by the ongoing conflict. Despite the work of the national and local health authorities with the support of aid organizations, during the mid-year rains up to 98% of children with diarrhea are unable to receive treatment services. Thus, it is recommended that community outreach or other delivery modalities through which services are delivered in closer proximity to those in need should be scaled up prior to and during these periods. This would serve to increase number of children able to receive treatment by lessening the prohibitive travel burden, or access constraint, on families during these times.
