Caregiver recognition of childhood diarrhea, care seeking behaviors and home treatment practices in rural Burkina Faso: a cross-sectional survey

Correlates of healthcare-seeking behavior for acute gastroenteritis-United States, October 1, 2016 -September 30, 2017

BACKGROUND

In the United States, public health surveillance systems often underestimate the burden of acute gastroenteritis (AGE) because they only identify disease among those who interact with the healthcare system.

OBJECTIVE

To identify factors associated with healthcare-seeking behavior among individuals experiencing community-acquired AGE.

METHODS

From October 2016 -September 2017, we conducted a weekly, age-stratified, random sample of Kaiser Permanente Northwest members located in northwest Oregon and southwest Washington, United States. Individuals who completed the online survey and experienced AGE were included in the analysis. Univariate and multivariable logistic regressions were performed to identify predictors of healthcare-seeking behavior.

RESULTS

Of the 3,894 survey respondents, 395 experienced an AGE episode and were eligible for analysis, of whom, 82 (21%) sought care for their AGE episode. In the final multivariable model, individuals with a concurrent fever (odds ratio [OR]: 4.76, 95% confidence interval [95% CI]: 2.48-9.13), increased diarrhea duration (≥6 days vs 1-4 days, OR: 4.22, 95% CI: 1.78-10.03), or increased vomiting duration (≥3 days vs 1 days, OR: 2.97, 95% CI: 1.22-7.26), were significantly more likely to seek healthcare. In the adjusted model, no sociodemographic or chronic disease variables were associated with healthcare-seeking behavior.

CONCLUSION

These findings suggest that individuals with a short duration of AGE and those without concurrent fever are underrepresented in healthcare facility-based surveillance systems.

Determinants of health care seeking behavior for childhood infectious diseases and malnutrition: A slum-based survey from Bangladesh

This study aimed to explore the magnitude and determinants of health care seeking behaviors for common infectious disease and malnutrition among Bangladeshi under-five children living in slum areas. A cross-sectional study of 300 children-caregiver dyads was conducted in an urban slum of Bangladesh. Data were collected via a structured questionnaire with accompanying anthropometric assessments of children administered by research staff. Multiple logistic regression was employed to identify associated factors of health care seeking behaviors. Only 44.7% and 13.0% of respondents sought care for childhood infectious diseases and malnutrition, respectively. Being a male child, 2-5 years old, having ≤5 family members, monthly family income >125$, and living in close proximity to a health facility were found to be potential determinants of health care seeking behavior for childhood infectious diseases. Mother/caregivers with poor nutritional information knowledge and who had a child 2-5 years old reported engaging in less care seeking behaviors regarding their child's malnutrition compared to their counterparts. Caregivers of children under the age of 5 years old reported low participation in health care seeking behaviors in relation to childhood infectious disease and malnutrition. Families living in slums require additional support targeting health and nutritional educational programs.

The use of traditional medicine practitioner services for childhood illnesses among childbearing women: a multilevel analysis of demographic and health surveys in 32 sub-Saharan African countries

BACKGROUND

Insights into the use of traditional medicine practitioners (TMP)-for common childhood diseases such as diarrhea and respiratory infections are important to understand the role of Traditional Medicine (TM) in reducing the increasing childhood morbidity and mortality in sub-Saharan Africa (SSA). However, a comprehensive picture of TMP utilisation and its associated factors for childhood illness in SSA is lacking. This study aimed to estimate the prevalence of the use of traditional medicine practitioner services to treat childhood illnesses among women with children under five years old and to identify individual and community-level factors associated with TMP use in SSA.

METHODS

The analysis used Demographic and Health Surveys (DHS) dataset collected between 2010 and 2021 among 353,463 under-fives children from 32 SSA countries. Our outcome variable was the use of TMP for childhood illness, defined as having diarrhoea or fever/cough or both. Using STATA v14, we employed the random effect meta-analysis to estimate the pooled prevalence of TMP use for childhood illness and a two-level multivariable multilevel modelling to determine the individual and community-level factors associated with consultation of a TMP.

RESULTS

Approximately [2.80% (95%CI: 1.88-3.90)] women who sought healthcare for childhood illnesses utilised the service of a TMP with the highest occurring in Cote d'Ivoire [16.3% (95%CI: 13.87-19.06)] and Guinea (13.80% (95%CI: 10.74-17.57)] but the lowest in Sierra Leone [0.10%(95%CI:0.01-1.61)]. Specifically, approximately [1.95% (95%CI: 1.33-2.68)] and [1.09% (95%CI:0.67-1.60)] of women sought the service of a TMP for childhood diarrhea and fever/cough, respectively. Women with no formal education [AOR = 1.62;95%CI:1.23-2.12], no media access [AOR = 1.19;95%CI:1.02-1.39), who lived in a male-headed household [AOR = 1.64;95%CI:1.27-2.11], without health insurance [AOR = 2.37;95%CI: 1.53-3.66], who considered it a problem getting permission to visit a health facility [AOR = 1.23;95%CI:1.03-1.47] and who perceived the size of their children at birth to be above average[AOR = 1.20;95%CI:1.03-1.41] had higher odds of using TMP for childhood illnesses.

CONCLUSIONS

Although the prevalence of TMP for childhood illnesses appeared low, our findings highlight that TMPs continue to play a critical role in managing childhood illnesses in SSA. It is essential that policymakers and service providers should incorporate the potential role of TMPs in the design, review and implementation of child health policies in SSA. Also, the interventions for curtailing childhood illnesses should be focused on the characteristics of women who use TMPs for childhood diseases identified in our study.

Risk Factors for Mortality Among Children Younger Than Age 5 Years With Severe Diarrhea in Low- and Middle-income Countries: Findings From the World Health Organization-coordinated Global Rotavirus and Pediatric Diarrhea Surveillance Networks

BACKGROUND

Diarrhea is the second leading cause of death in children younger than 5 years of age globally. The burden of diarrheal mortality is concentrated in low-resource settings. Little is known about the risk factors for childhood death from diarrheal disease in low- and middle-income countries.

METHODS

Data from the World Health Organization (WHO)-coordinated Global Rotavirus and Pediatric Diarrhea Surveillance Networks, which are composed of active, sentinel, hospital-based surveillance sites, were analyzed to assess mortality in children <5 years of age who were hospitalized with diarrhea between 2008 and 2018. Case fatality risks were calculated, and multivariable logistic regression was performed to identify risk factors for mortality.

RESULTS

This analysis comprises 234 781 cases, including 1219 deaths, across 57 countries. The overall case fatality risk was found to be 0.5%. Risk factors for death in the multivariable analysis included younger age (for <6 months compared with older ages, odds ratio [OR] = 3.54; 95% confidence interval [CI], 2.81-4.50), female sex (OR = 1.18; 95% CI, 1.06-1.81), presenting with persistent diarrhea (OR = 1.91; 95% CI, 1.01-3.25), no vomiting (OR = 1.13; 95% CI, .98-1.30), severe dehydration (OR = 3.79; 95% CI, 3.01-4.83), and being negative for rotavirus on an enzyme-linked immunosorbent assay test (OR = 2.29; 95% CI, 1.92-2.74). Cases from the African Region had the highest odds of death compared with other WHO regions (OR = 130.62 comparing the African Region with the European Region; 95% CI, 55.72-422.73), whereas cases from the European Region had the lowest odds of death.

CONCLUSIONS

Our findings support known risk factors for childhood diarrheal mortality and highlight the need for interventions to address dehydration and rotavirus-negative diarrheal infections.

Childhood diarrhoea: a cross-sectional survey on maternal knowledge, hygienic practices and use of oral zinc for home management in a Nigerian community

Introduction

diarrhoea is the second leading cause of morbidity and mortality in young children. The aim was to assess maternal knowledge, hygienic practices and home management (HM) of diarrhoea with oral rehyrdation therapy (ORT) and oral zinc in children aged 6-23 months in western Nigeria. Predictors of good knowledge and practice were also assessed.

Methods

this was a community based analytic cross-sectional study. Multistage sampling was used to select mothers of children 6-23 months of age. Data were collected using pre-tested, interviewer administered questionnaires and analyzed using SPSS version 20. Bivariate analysis and multiple logistic regression for predictor variables were done. Level of significance was set at 0.05.

Results

three hundred and seventy one (371) respondents were interviewed (mean age 30.4 ± 5.02 years). 305 (82.2%) had good knowledge of diarrhoeal diseases, 208(56.1%) had good knowledge of home management of childhood diarrhoea, 274 (73.9%) had good maternal hygienic practices and 161 (61.2%) of the 263 mothers who had managed diarrhoea in their children, had good practice. Only 34 (12.9%) of them used zinc tablets and 11 (32.4%) did not complete the full course. Maternal age 30-39 years predicted good knowledge (AOR 3.19 CI 2-6.05). Predictors of good home management practices were: maternal age 30-39 years (AOR 2.78 CI 1.44-5.37), >40 years (AOR 5.55 CI 1.54-20.01) and younger age of the index child, 6-11 months (AOR 4.83 CI 2.29-10.18).

Conclusion

mothers had poor knowledge of the role of zinc supplementation in childhood diarrhoea and use of zinc tablets for diarrhoea was very low. Community based health education should be carried out.

Risk factors for childhood illness and death in rural Uttar Pradesh, India: perspectives from the community, community health workers and facility staff

BACKGROUND

Uttar Pradesh (UP), India continues to have a high burden of mortality among young children despite recent improvement. Therefore, it is vital to understand the risk factors associated with under-five (U5) deaths and episodes of severe illness in order to deliver programs targeted at decreasing mortality among U5 children in UP. However, in rural UP, almost every child has one or more commonly described risk factors, such as low socioeconomic status or undernutrition. Determining how risk factors for childhood illness and death are understood by community members, community health workers and facility staff in rural UP is important so that programs can identify the most vulnerable children.

METHODS

This qualitative study was completed in three districts of UP that were part of a larger child health program. Twelve semi-structured interviews and 21 focus group discussions with 182 participants were conducted with community members (mothers and heads of households with U5 children), community health workers (CHWs; Accredited Social Health Activists and Auxiliary Nurse Midwives) and facility staff (medical officers and staff nurses). All interactions were recorded, transcribed and translated into English, coded and clustered by theme for analysis. The data presented are thematic areas that emerged around perceived risk factors for childhood illness and death.

RESULTS

There were key differences among the three groups regarding the explanatory perspectives for identified risk factors. Some perspectives were completely divergent, such as why the location of the housing was a risk factor, whereas others were convergent, including the impact of seasonality and certain occupational factors. The classic explanatory risk factors for childhood illness and death identified in household surveys were often perceived as key risk factors by facility staff but not community members. However, overlapping views were frequently expressed by two of the groups with the CHWs bridging the perspectives of the community members and facility staff.

CONCLUSION

The bridging views of the CHWs can be leveraged to identify and focus their activities on the most vulnerable children in the communities they serve, link them to facilities when they become ill and drive innovations in program delivery throughout the community-facility continuum.

Sociodemographic Determinants of Healthcare-Seeking Options and Alternative Management Practices of Childhood Diarrheal Illness: A Household Survey among Mothers in Iraq

Diarrhea remains a significant cause of child morbidity and mortality in Iraq. The objective of this study was to examine the current practices of home-based management of diarrheal illnesses among Iraqi children. We surveyed mothers of children aged less than 5 years to identify the sociodemographic factors associated with maternal healthcare-seeking practices. A total of 500 mother-child pairs were interviewed in a cross-sectional household survey in Thi-Qar Governorate, southeastern Iraq, between March 2016 and February 2017. Logistic and multinomial regression models were used to infer sociodemographic predictors of the healthcare-seeking and alternative management practices adopted by the mothers. The interviewees reported that 35.2% of their children had diarrhea in the 2 weeks before the survey. The least likelihood of reported occurrence of diarrhea was among mother-child pairs where the mothers had received university education, as compared with mothers who were illiterate or received only primary or secondary education. Lower odds (odds ratio = 0.4, P-value < 0.001) of reported childhood diarrhea was revealed among mothers aged > 25 years than among those younger. Self-ordered medicine from a pharmacy was the most preferred alternative management option in almost half (52.4% [262/500]) of the interviewed mothers in Thi-Qar. Interestingly, 69.6% (348/500) of the mothers reported supplying their children suffering from diarrhea with antibiotics. Relative to mothers with university education, those with high school education had more likelihood of selecting medical center (relative risk ratio [rrr] = 2.4) and pharmacy (rrr = 3.7) as against no treatment. Lower maternal educational level, mothers' age < 25 years, and the district of residence were important factors associated with diarrhea occurrence among children younger than 5 years. In light of the findings from this study, intervention aimed at improving healthcare seeking for managing diarrhea in Iraqi children should jointly consider the influence of mothers age, education, as well as the level of economic status of the communities in which mothers of these children reside. The results of this study indicate the need for enhancing public health education to improve the maternal management of diarrheal disease and the avoidance of unnecessary use of antimicrobials.

Value of Eye-Tracking Data for Classification of Information Processing-Intensive Handling Tasks: Quasi-Experimental Study on Cognition and User Interface Design

Background

In order to give a wide range of people the opportunity to ensure and support home care, one approach is to develop medical devices that are as user-friendly as possible. This allows nonexperts to use medical devices that were originally too complicated to use. For a user-centric development of such medical devices, it is essential to understand which user interface design best supports patients, caregivers, and health care professionals.

Objective

Using the benefits of mobile eye tracking, this work aims to gain a deeper understanding of the challenges of user cognition. As a consequence, its goal is to identify the obstacles to the usability of the features of two different designs of a single medical device user interface. The medical device is a patient assistance device for home use in peritoneal dialysis therapy.

Methods

A total of 16 participants, with a subset of seniors (8/16, mean age 73.7 years) and young adults (8/16, mean age 25.0 years), were recruited and participated in this study. The handling cycle consisted of seven main tasks. Data analysis started with the analysis of task effectiveness for searching for error-related tasks. Subsequently, the in-depth gaze data analysis focused on these identified critical tasks. In order to understand the challenges of user cognition in critical tasks, gaze data were analyzed with respect to individual user interface features of the medical device system. Therefore, it focused on the two dimensions of dwell time and fixation duration of the gaze.

Results

In total, 97% of the handling steps for design 1 and 96% for design 2 were performed correctly, with the main challenges being task 1 insert, task 2 connect, and task 6 disconnect for both designs. In order to understand the two analyzed dimensions of the physiological measurements simultaneously, the authors propose a new graphical representation. It distinguishes four different patterns to compare the eye movements associated with the two designs. The patterns identified for the critical tasks are consistent with the results of the task performance.

Conclusions

This study showed that mobile eye tracking provides insights into information processing in intensive handling tasks related to individual user interface features. The evaluation of each feature of the user interface promises an optimal design by combining the best found features. In this way, manufacturers are able to develop products that can be used by untrained people without prior knowledge. This would allow home care to be provided not only by highly qualified nurses and caregivers, but also by patients themselves, partners, children, or neighbors.

Strong community-based health systems and national governance predict improvement in coverage of oral rehydration solution (ORS): a multilevel longitudinal model

Diarrheal disease remains a leading cause of child death globally, especially in low and middle-income countries. Use of oral rehydration solution (ORS) for treatment of diarrhea in children, a very cost-effective intervention, remains below 50% in many countries. Here we use a multi-level longitudinal model to reveal important predictors of ORS use at the national level. The findings suggest that increasing government effectiveness along with increased implementation and affordability of community-based health programs can lead to substantial increases in ORS use. Key informant interviews with national health leaders in countries that significantly improved ORS coverage support these quantitative findings.

Prevalence of diarrheal illness and healthcare-seeking behavior by age-group and sex among the population of Gaza strip: a community-based cross-sectional study

BACKGROUND

In the Gaza strip, diarrhea is one of main reasons for children visiting primary healthcare centers. Hence, we investigate predictors of the diarrheal illness and health care-seeking behavior among different age groups.

METHODS

This community-based cross-sectional survey was conducted from August 2017 to June 2018 among 1857 households. A pretested structured questionnaire included information about socio-demographic, sanitation, hygiene, source of water, diarrheal illness, and seeking healthcare in households was administered to head of household. To achieve representativeness for the five Gaza's governorates, a cluster random sampling was applied.

RESULTS

Of the 1857 household's heads, 421 (22.7%) reported an episode of diarrhea during the 48 h preceding the interview resulting an overall prevalence rate of 3.8 per 100 individuals. The prevalence of diarrhea was statistical significant greater in males (5.4/100) compared to females (1.3/100) in all age groups (p <  0.05). Socio-demographic, economic, water, sanitation, and hygiene factors were predictors of the diarrheal illness and seeking of non-professional healthcare for diarrhea illness treatment among. A transition behavior from professional to non-professional and vice versa in seeking healthcare in each diarrheal episode was found.

CONCLUSIONS

We recommend improving the status of water, sanitation, and hygiene in the Gaza strip's households to reduce diarrhea among the population of Gaza strip. Community sensitization about the importance of seeking care at primary health centers because treatment of children is available for free or in low costs.

Assessment of Poor Home Management Practice of Diarrhea and Associated Factors among Caregivers of Under-Five Years Children in Urban and Rural Residents of Doba Woreda, Ethiopia: Comparative Cross-Sectional Study

Background

Diarrhea is the first cause of illness and the second cause of death in under-five children. Home interventions can prevent 57% of mortality related to diarrhea. However, malpractices were common and the reason for this underutilization was unclear. Thus, this study was aimed at assessing poor home management practice of Diarrhea and associated factors among caregivers of under-five years children in urban and rural residents.

Methods

The community-based comparative cross-sectional study was conducted in Doba woreda, Ethiopia, from February 25 to March 15, 2017. Multistage cluster sampling technique was used to study 559 caregivers. An interviewer administered pretested structured questionnaire was used to collect data. Collected data were entered into Epi Info version 3.5.1 and exported to statistical package for social sciences (SPSS) version 20.0 for analysis. The binary logistic regression model was used. In bivariate analysis p-value<0.25 was taken into multivariable analysis. Adjusted odds ratios with their corresponding 95% of CI were used to report results with a significance level of p-value<0.05.

Result

184 urban and 375 rural caregivers were included in the study. Poor home management practice was 55.8% of urban and 85.6% of rural residents. Knowledge level (AOR=2.7(CI[1.3, 6.5]) and AOR=13.4(CI[5.3, 34.0]) and difficulty in preparing oral rehydration salt (AOR=4.0CI[1.4, 11.0]) and AOR=2.4(1.3, 5.3)) were associated factors for both urban and rural residents, respectively. Caregivers of male index child (AOR=2.3(1.2, 4.7)) and age of the caregivers (AOR=0.26(0.09, 0.8)) were associated with poor home practice for urban residents. In rural residents, inaccessibility to zinc supplementation (AOR=2.4(1.2, 5.0)) was among associated factors.

Conclusion

Poor home management practice of diarrhea was high in both urban and rural residents. It was higher in rural compared to urban residents. Poor practice was associated with knowledge level, age of the caregivers, sex of the index child, and accessibility of zinc. Health education and community mobilization on home management of diarrhea are important to increase awareness and improve practice level.

Knowledge and practices of mothers and caregivers on diarrhoeal management among under 5-year-old children in a medium-size town of Senegal

In 2016, about one out of 10 children in sub-Saharan Africa died due to diarrhoea, causing an estimated burden of 25 million disability-adjusted life years. A prominent cause of death is dehydration linked to lack of knowledge and adequate management of diarrhoeal episodes. This study assessed knowledge and practices of mothers and caregivers on diarrhoeal management among under 5-year-old children in a medium-size town of Senegal. A cross-sectional survey was carried out between September and October 2016 in four zones of Mbour, located in the south-western part of Senegal. Mothers and caregivers of children under the age of 5 years were interviewed to determine their levels of knowledge and management practice of diarrhoea. The association between diarrhoea and source of care was determined using logistic regression analyses. In total, 367 mothers and caregivers who reported a diarrhoeal episode in at least one of their children under 5 years of age were included. Slightly less than a quarter (23.2%, 95% confidence interval (CI) 18.9-27.8%) of respondents had good management practice of diarrhoea, while 40.0% (95% CI: 34.5-45.6%) had high level of knowledge about diarrhoea. Mothers and caregivers having sought care from public health facilities had two and four times higher odds of good knowledge and good management practices of diarrhoea, respectively, compared to those seeking no care outside the home or from traditional healers. The weakness regarding knowledge and quality management practice, particularly the poor use of internationally recommended treatment of childhood diarrhoea among mothers and caregivers, confirms the low coverage of oral rehydration salt and zinc and lack of sensitization about diarrhoea. We conclude that diarrhoea management practices in this part of Senegal do not correspond with international recommendations, even when mothers and caregivers visit government health facilities. There is a need to develop and implement communication strategies for health care providers' and the mothers and caregivers in order to facilitate sustainable positive change in the management of childhood diarrhoea at the community level. Moreover, mothers, caregivers and health care providers need specific training on the current guidelines for diarrhoea management.

Epidemiological investigation and management of bloody diarrhea among children in India

BACKGROUND

The evidence on the factors associated with childhood bloody diarrhea in developing countries in general and India, in particular, is somewhat limited. Our study, therefore, examines-the prevalence of bloody diarrhea; the magnitude of treatment of bloody diarrhea (use of both oral rehydration and antibiotics (pills, syrups, and injections)); and several other associated factors with bloody diarrhea in the youngest children under five years in the Indian context.

METHODS

We used data from the National Family Health Survey (NFHS)-4 conducted in 2015-16. We used a multivariable binary logistic regression model to identify the factors associated with bloody diarrhea. We also applied a multinomial logistic regression model to identify associated factors with the treatment of bloody diarrhea amongst the youngest children below five years.

FINDINGS

The overall prevalence of bloody diarrhea in the youngest children was about 9 percent in the last two weeks preceding the survey. There was a significant difference in the mean age of those children having bloody diarrhea and watery diarrhea during the same period. Children whose stools were disposed of unsafely and those who belonged to households with neither a place nor water for washing hands were more likely to suffer from bloody diarrhea compared to their counterparts with these facilities. About a little less than one-fifth of the youngest children (16%) received adequate treatment of bloody diarrhea. The treatment of bloody diarrhea was associated with the health facility and maternal and children's socioeconomic and demographic characteristics.

CONCLUSION

The study shows that household environmental risk factors are important predictors of bloody diarrhea amongst the youngest children. Still, 28% of those children did not receive any treatment of bloody diarrhea in India. There is also a clear need to promote the practice of safe disposal of children's stools and handwashing among mothers and children. Mothers need to be sensitized about the necessity of an immediate visit to a health facility/center in case of bloody diarrhea.

Feeding Practice during Diarrheal Episode among Children Aged between 6 to 23 Months in Mirab Abaya District, Gamo Gofa Zone, Southern Ethiopia

Background

Diarrheal disease is one of the main causes of childhood malnutrition. In developing countries 30% of pediatric beds are occupied with children having diarrheal disease. Fluid replacement, continued feeding, and increasing appropriate fluid at home during the diarrhea episodes are the cornerstone of treatment package. The purpose of this study was to assess feeding practice during diarrheal episodes among children aged 6 to 23 months in Mirab Abaya district, Gamo Gofa Zone, South Ethiopia.

Methods

Community-based cross-sectional study design was conducted from February to March 2016 among children aged 6 to 23 months. A multistage sampling technique was used to select the study participants. A total of 661 participants were included in our study. Data were entered into Epi data version 3.1 and exported to SPSS 20.0 statistical software for analysis. Bivariate and multivariable analysis were done to assess factors associated with feeding practices during a diarrheal episode. Odds ratio with 95% CI was used to identify a statistically significant association between independent variables and feeding practice during diarrheal episode.

Result

The proportion of proper feeding practice during diarrheal episode was 467 (70.7%). Boy children were about 1.6 times [AOR; 1.62 (95%CI=1.04, 2.50)] more likely to receive increased food and fluid than girl children. Mothers who have one under-five child were 2 times [AOR 2.11 (95% CI =1. 38, 3.23)] more likely to have proper feeding practice during diarrheal episode as compared to those have two and more under-five children. The likelihood of increasing food and fluid during diarrheal episodes was 2 times [AOR 2.46 (95% CI=1. 55, 3.88)] higher among children from maternal age of 30-39 years than those from 20-29 years. Mothers who get information about feeding practices during diarrheal episodes were 2 times [AOR 2.19 (95% CI=1. 43, 3.36)] more likely to increase food and fluid to their child compared to their counterparts.

Conclusion

In this study educational status, number of antenatal care visits, sex, number of under-5 children, maternal age, and mothers information about feeding practice were independently associated with feeding practices during a diarrheal episode. Therefore, intensive intervention programme should focus on these determinants to reduce child mortality and morbidity and realize sustainable development goals.

Distance to care, care seeking and child mortality in rural Burkina Faso: findings from a population-based cross-sectional survey

Objective

Although distance has been identified as an important barrier to care, evidence for an effect of distance to care on child mortality is inconsistent. We investigated the association of distance to care with self‐reported care seeking behaviours, neonatal and post‐neonatal under‐five child mortality in rural areas of Burkina Faso.

Methods

We performed a cross‐sectional survey in 14 rural areas from November 2014 to March 2015. About 100 000 women were interviewed on their pregnancy history and about 5000 mothers were interviewed on their care seeking behaviours. Euclidean distances to the closest facility were calculated. Mixed‐effects logistic and Poisson regressions were used respectively to compute odds ratios for care seeking behaviours and rate ratios for child mortality during the 5 years prior to the survey.

Results

Thirty per cent of the children lived more than 7 km from a facility. After controlling for confounding factors, there was a strong evidence of a decreasing trend in care seeking with increasing distance to care (P ≤ 0.005). There was evidence for an increasing trend in early neonatal mortality with increasing distance to care (P = 0.028), but not for late neonatal mortality (P = 0.479) and post‐neonatal under‐five child mortality (P = 0.488). In their first week of life, neonates living 7 km or more from a facility had an 18% higher mortality rate than neonates living within 2 km of a facility (RR = 1.18; 95%CI 1.00, 1.39; P = 0.056). In the late neonatal period, despite the lack of evidence for an association of mortality with distance, it is noteworthy that rate ratios were consistent with a trend and similar to or larger than estimates in early neonatal mortality. In this period, neonates living 7 km or more from a facility had an 18% higher mortality rate than neonates living within 2 km of a facility (RR = 1.18; 95%CI 0.92, 1.52; P = 0.202). Thus, the lack of evidence may reflect lower power due to fewer deaths rather than a weaker association.

Conclusion

While better geographic access to care is strongly associated with increased care seeking in rural Burkina Faso, the impact on child mortality appears to be marginal. This suggests that, in addition to improving access to services, attention needs to be paid to quality of those services.

Fecal Indicator Bacteria along Multiple Environmental Transmission Pathways (Water, Hands, Food, Soil, Flies) and Subsequent Child Diarrhea in Rural Bangladesh

Enteric pathogens can be transmitted through multiple environmental pathways, yet little is known about the relative contribution of each pathway to diarrhea risk among children. We aimed to identify fecal transmission pathways in the household environment associated with prospectively measured child diarrhea in rural Bangladesh. We measured the presence and levels of Escherichia coli in tube wells, stored drinking water, pond water, child hand rinses, courtyard soil, flies, and food in 1843 households. Gastrointestinal symptoms among children ages 0-60 months were recorded concurrently at the time of environmental sample collection and again a median of 6 days later. Incident diarrhea (3 or more loose stools in a 24-h period) was positively associated with the concentration of E. coli on child hands measured on the first visit (incidence rate ratio [IRR] = 1.23, 95% CI 1.06, 1.43 for a log₁₀ increase), while other pathways were not associated. In cross-sectional analysis, there were no associations between concurrently measured environmental contamination and diarrhea. Our findings suggest higher levels of E. coli on child hands are strongly associated with subsequent diarrheal illness rates among children in rural Bangladesh.

Determinants of primary healthcare seeking behaviours for children during the first 18 months of life in Benin

Background

Primary healthcare is a key element of management of childhood illness in Africa. The objectives were to identify primary care seeking determinants among infants and young children up to 18 mo in a birth cohort from Benin.

Methods

From 2007 to 2009 in Benin, a birth cohort was followed until the age of 18 mo in three health centres. Multilevel Poisson regression models were fitted to identify the factors related to the monthly number of consultations. Maternal and newborn characteristics and infant general health parameters were considered.

Results

A total of 566 children were followed. On average, 0.46 consultations per month per child were recorded. The number of consultations was significantly lower after the first 6 mo of life (p<0.001). A distance >1000 m was associated with fewer consultations (p=0.01). Primiparity was significantly associated with higher care seeking (relative risk 1.17 [95% CI 1.05 to 1.30], p<0.01). No child characteristics at birth were significantly associated with the number of consultations (all p>0.16).

Conclusions

Development of health structures and improvement of access remain important goals for strengthening of the primary care health system. Studying factors of care seeking behaviour, like parity, can help to identify women more prone to seek care for their child during the first year of life.

Pediatric out-of-hospital deaths following hospital discharge: a mixed-methods study

BACKGROUND

Out-of-hospital death among children living in resource poor settings occurs frequently. Little is known about the location and circumstances of child death following a hospital discharge.

OBJECTIVES

This study aimed to understand the context surrounding out-of-hospital deaths and the barriers to accessing timely care for Ugandan children recently discharged from the hospital.

METHODS

This was a mixed-methods sub-study within a larger cohort study of post-discharge mortality conducted in the Southwestern region of Uganda. Children admitted with an infectious illness were eligible for enrollment in the cohort study, and then followed for six months after discharge. Caregivers of children who died outside of the hospital during the six month post-discharge period were eligible to participate in this sub-study. Qualitative interviews and univariate logistic regression were conducted to determine predictors of out-of-hospital deaths.

RESULTS

Of 1,242 children discharged, 61 died during the six month post-discharge period, with most (n=40, 66%) dying outside of a hospital. Incremental increases in maternal education were associated with lower odds of out-of-hospital death compared to hospital death (OR: 0.38, 95% CI: 0.19 - 0.81). The qualitative analysis identified health seeking behaviors and common barriers within the post-discharge period which delayed care seeking prior to death. For recently discharged children, caregivers often expressed hesitancy to seek care following a recent episode of hospitalization.

CONCLUSION

Mortality following discharge often occurs outside of a hospital context. In addition to resource limitations, the health knowledge and perceptions of caregivers can be influential to timely access to care. Interventions to decrease child mortality must consider barriers to health seeking among children following hospital discharge.

Comparison of Preventive and Therapeutic Zinc Supplementation in Young Children in Burkina Faso: A Cluster-Randomized, Community-Based Trial

BACKGROUND

The WHO and UNICEF recommend therapeutic zinc supplementation (TZS) for the treatment of diarrhea. In zinc-deficient populations, preventive zinc supplementation might provide greater benefits for reducing diarrhea and malaria incidence and increasing growth and plasma zinc (pZn) concentration. If effective, intermittent preventive zinc supplementation (IPZS) would cost less than daily preventive zinc supplementation (DPZS).

OBJECTIVE

We assessed the effects of IPZS, DPZS, and TZS in children on the primary outcomes of diarrhea incidence, malaria incidence, growth, and pZn concentration compared with nonsupplemented control groups.

METHODS

Rural Burkinabe children (n = 7641; 6-30 mo old) in 36 clusters were randomly assigned to 1 of 5 treatment groups for 16, 32, or 48 wk: 1) IPZS (10 mg Zn/d for 10 d every 16 wk); 2) DPZS (7 mg Zn/d); 3) TZS (20 mg Zn/d for 10 d for diarrhea); 4) morbidity surveillance control (MSC); or 5) nonintervention control (NIC). Supplemented groups remained masked until completion of primary analyses with mixed models.

RESULTS

At baseline, stunting (28.6%) and low pZn concentration (<65 μg/dL; 43.5%) were common. After 48 wk, mean ± SE pZn increased more (P = 0.008) in the DPZS group (3.9 ± 1.3 μg/dL) than in the TZS (-0.5 ± 1.2 μg/dL) and NIC (-1.2 ± 0.9 μg/dL) groups. All supplemented groups had a moderately lower incidence of reported diarrhea (0.48-0.49 compared with 0.57 episodes/100 d, P = 0.001) and reported fever (1.1-1.2 compared with 1.5 episodes/100d, P < 0.001) and gained slightly less length (3.15-3.20 compared with 3.36 cm/16 wk, P < 0.001) than the MSC group, but did not differ from each other. Prevalence of diarrhea and incidences of confirmed fever and malaria were not different across study groups.

CONCLUSIONS

The preventive and TZS groups had reduced diarrhea incidence, but it is uncertain whether this resulted from a functional response to zinc or reporting bias. The comparison should be re-examined in populations known to respond to zinc supplementation. This trial was registered at www.clinicaltrials.gov as NCT00944359.

Social determinants of child mortality in Niger: Results from the 2012 National Verbal and Social Autopsy Study

Background

Understanding the determinants of preventable deaths of children under the age of five is important for accelerated annual declines – even as countries achieve the UN’s Millennium Development Goals and the target date of 2015 has been reached. While research has documented the extent and nature of the overall rapid decline in child mortality in Niger, there is less clear evidence to provide insight into the contributors to such deaths. This issue is the central focus of this paper.

Methods

We analyzed a nationally representative cross–sectional sample of 620 child deaths from the 2012 Niger Verbal Autopsy/Social Autopsy (VASA) Survey. We conducted a descriptive analysis of the data on preventive and curative care, guided by the coverage of proven indicators along the continuum of well child care and illness recognition and care–seeking for child illnesses encompassed by the BASICS/CDC Pathway to Survival model.

Results

Six hundred twenty deaths of children (1–59 months of age) were confirmed from the VASA survey. The majority of these children lived in households with precarious socio–economic conditions. Among the 414 children whose fatal illnesses began at age 0–23 months, just 24.4% were appropriately fed. About 24% of children aged 12–59 months were fully immunized. Of 601 children tracked through the Pathway to Survival, 62.4% could reach the first health care provider after about 67 minutes travel time. Of the 306 children who left the first health care provider alive, 161 (52.6%) were not referred for further care nor received any home care recommendations, and just 19% were referred to a second provider. About 113 of the caregivers reported cost (35%), distance (35%) and lack of transport (30%) as constraints to care–seeking at a health facility.

Conclusion

Despite Niger’s recent major achievements in reducing child mortality, the following determinants are crucial to continue building on the gains the country has made: improved socio–economic state of the poor in the country, investment in women’s education, adoption of the a law to prevent marriage of young girls before 18 years of age, and implementation of health programs that encourage breastfeeding and complementary feeding, immunization, illness recognition, prompt and appropriate care–seeking, and improved referral rates.

Harmful practices in the management of childhood diarrhea in low- and middle-income countries: a systematic review

BACKGROUND

Harmful practices in the management of childhood diarrhea are associated with negative health outcomes, and conflict with WHO treatment guidelines. These practices include restriction of fluids, breast milk and/or food intake during diarrhea episodes, and incorrect use of modern medicines. We conducted a systematic review of English-language literature published since 1990 to assess the documented prevalence of these four harmful practices, and beliefs, motivations, and contextual factors associated with harmful practices in low- and middle-income countries.

METHODS

We electronically searched PubMed, Embase, Ovid Global Health, and the WHO Global Health Library. Publications reporting the prevalence or substantive findings on beliefs, motivations, or context related to at least one of the four harmful practices were included, regardless of study design or representativeness of the sample population.

RESULTS

Of the 114 articles included in the review, 79 reported the prevalence of at least one harmful practice and 35 studies reported on beliefs, motivations, or context for harmful practices. Most studies relied on sub-national population samples and many were limited to small sample sizes. Study design, study population, and definition of harmful practices varied across studies. Reported prevalence of harmful practices varied greatly across study populations, and we were unable to identify clearly defined patterns across regions, countries, or time periods. Caregivers reported that diarrhea management practices were based on the advice of others (health workers, relatives, community members), as well as their own observations or understanding of the efficacy of certain treatments for diarrhea. Others reported following traditionally held beliefs on the causes and cures for specific diarrheal diseases.

CONCLUSIONS

Available evidence suggests that harmful practices in diarrhea treatment are common in some countries with a high burden of diarrhea-related mortality. These practices can reduce correct management of diarrheal disease in children and result in treatment failure, sustained nutritional deficits, and increased diarrhea mortality. The lack of consistency in sampling, measurement, and reporting identified in this literature review highlights the need to document harmful practices using standard methods of measurement and reporting for the continued reduction of diarrhea mortality.

Diapers in war zones: ethnomedical factors in acute childhood gastroenteritis in Peshawar, Pakistan

This article considers ethnomedical knowledge and practices among parents related to contraction of acute gastroenteritis among children in Peshawar, Pakistan. Research methods included analysis of the Emergency Pediatric Services' admission register, a structured interview administered to 47 parents of patients seen in the Khyber Medical College Teaching Hospital, semi-structured interviews of 12 staff, and four home visits among families with children treated at the hospital. The use of native research assistants and participant observation contributed to the reliability of the findings, though the ethnographic, home-visit sample is small. Our research indicated that infection rates are exacerbated in homes through two culturally salient practices and one socioeconomic condition. Various misconceptions propagate the recurrence or perserverance of acute gastroenteritis including assumptions about teething leading to poor knowledge of disease etiology, rehydration solutions leading to increased severity of disease, and diaper usage leading to the spread of disease. In our Discussion, we suggest how hospital structures of authority and gender hierarchy may impact hospital interactions, the flow of information, and its respective importance to the patient's parents leading to possible propagation of disease. These ethnographic data offer a relatively brief but targeted course of action to improve the effectiveness of prevention and treatment efforts.

Multi-country analysis of routine data from integrated community case management (iCCM) programs in sub-Saharan Africa

Aim

To identify better performing iCCM programs in sub–Saharan Africa (SSA) and identify factors associated with better performance using routine data.

Methods

We examined 15 evaluations or studies of integrated community case management (iCCM) programs in SSA conducted between 2008 and 2013 and with information about the program; routine data on treatments, supervision, and stockouts; and, where available, data from community health worker (CHW) surveys on supervision and stockouts. Analyses included descriptive statistics, Fisher exact test for differences in median treatment rates, the Kruskal-Wallis test for differences in the distribution of treatment rates, and Spearman’s correlation by program factors.

Results

The median percent of annual expected cases treated was 27% (1–74%) for total iCCM, 37% (1–80%) for malaria, 155% (7–552%) for pneumonia, and 27% (1–74%) for diarrhoea. Seven programs had above median total iCCM treatments rates. Four programs had above median treatment rates, above median treatments per active CHW per month, and above median percent of expected cases treated. Larger populations under–five targeted were negatively associated with treatment rates for fever, malaria, diarrhea, and total iCCM. The ratio of CHWs per population was positively associated with diarrhoea treatment rates. Use of rapid diagnostic tests (RDTs) was negatively associated with treatment rates for pneumonia. Treatment rates and percent of annual expected cases treated were equivalent between programs with volunteer CHWs and programs with salaried CHWs.

Conclusions

There is large variation in iCCM program performance in SSA. Four programs appear to be higher performing in terms of treatment rates, treatments per CHW per month, and percent of expected cases treated. Treatment rates for diarrhoea are lower than expected across most programmes. CHWs in many programmes are overtreating pneumonia. Programs targeting larger populations under–five tend to have lower treatment rates. The reasons for lower pneumonia treatment rates where CHWs use RDTs need to be explored. Programs with volunteer CHWs and those with salaried CHWs can achieve similar treatment rates and percent of annual expected cases treated but to do so volunteer programs must manage more CHWs per population and salaried CHWs must provide more treatments per CHW per month.

Prevalence, one week incidence and knowledge on causes of diarrhea: household survey of under-fives and adults in Mkuranga district, Tanzania

Background

Diarrhea is known to be the major cause of mortality in children aged less than five years old. Although mortality from diarrheal disease is decreasing globally, morbidity is not. The objectives of this study were to determine the prevalence of diarrhea among under-fives and assess knowledge on causes of diarrhea among adults in Mkuranga district Tanzania.

Methods

Interviews with heads of households and observations were the methods of data collection employed by this study.

Results

The prevalence of diarrhea in children below the age of five years as reported by heads of households was 6.1% and most affected were children in age groups 12 – 17 and 18 – 23 months (11.6% and 15.8% respectively; p – value 0.001). The rate of diarrhea incidence was 1 episode per 10 children per week. The mean duration of diarrhea illness was 1.7 days. Most under-fives had diarrhea for one (38.1%) or two (24%) days. Respondents in the 4th least poor quintile were more likely to have comprehensive knowledge on causes of diarrhea compared to respondents in the 1st poorest quintile. Male respondents were two times more likely to have comprehensive knowledge than female respondents. Respondents with comprehensive knowledge on causes of diarrhea were less likely to have poor hand-washing practice and more likely to have received water, hygiene and sanitation education. Under-fives in age group 12 – 17 months and those from households with reported poor hand washing practice were more likely to experience diarrhea episodes.

Conclusion

Although prevalence of diarrhea reported in this study is low, the one week incidence is moderately high but less severe. Majority of household respondents had inadequate knowledge on causes of diarrhea and poor hand-washing practice. There is a need to provide WASH education to improve their knowledge on causes of diarrhea and hand washing practice.

Diarrhoea prevalence in children under five years of age in rural Burundi: an assessment of social and behavioural factors at the household level

BACKGROUND

Diarrhoea is the second leading cause of child mortality worldwide. Low- and middle-income countries are particularly burdened with this both preventable and treatable condition. Targeted interventions include the provision of safe water, the use of sanitation facilities and hygiene education, but are implemented with varying local success.

OBJECTIVE

To determine the prevalence of and factors associated with diarrhoea in children under five years of age in rural Burundi.

DESIGN

A cross-sectional survey was conducted among 551 rural households in northwestern Burundi. Areas of inquiry included 1) socio-demographic information, 2) diarrhoea period prevalence and treatment, 3) behaviour and knowledge, 4) socio-economic indicators, 5) access to water and water chain as well as 6) sanitation and personal/children's hygiene.

RESULTS

A total of 903 children were enrolled. The overall diarrhoea prevalence was 32.6%. Forty-six per cent (n=255) of households collected drinking water from improved water sources and only 3% (n=17) had access to improved sanitation. We found a lower prevalence of diarrhoea in children whose primary caretakers received hygiene education (17.9%), boiled water prior to its utilisation (19.4%) and were aged 40 or older (17.9%). Diarrhoea was associated with factors such as the mother's age being less than 25 and the conviction that diarrhoea could not be prevented. No gender differences were detected regarding diarrhoea prevalence or the caretaker's decision to treat.

CONCLUSIONS

Diarrhoea prevalence can be reduced through hygiene education and point-of use household water treatment such as boiling. In order to maximise the impact on children's health in the given rural setting, future interventions must assure systematic and regular hygiene education at the household and community level.

Rural-urban disparities in maternal immunization knowledge and childhood health-seeking behavior in Nigeria: a mixed method study

BACKGROUND

Immunization and appropriate health-seeking behavior are effective strategies to reduce child deaths.

OBJECTIVES

To compare maternal knowledge about immunization, use of growth chart and childhood health-seeking behavior in rural and urban areas.

METHODS

A cross-sectional comparative study done in Lagos, Nigeria. Questionnaire survey and focus group discussions were done. 300 respondents were selected by multi-stage sampling while discussants were purposively selected.

RESULTS

Awareness of immunization was high but knowledge of vaccine preventable diseases (VPDs) was poor in both areas. Urban women utilized preventive services more; growth monitoring (p<0.001) and immunization (p<0.001) while higher proportions of rural women utilized nutritional counseling (p=0.005) and treatment of illness (p<0.001). Growth chart utilization was better in the urban areas (p<0.001). Increasing maternal education increased use of growth chart in both areas. Both groups of women use multiple treatment sources for children (more in urban), determined by cost, time, perceived severity of illness and type of ailment (urban) and peculiarity of illness (rural). There is a preference for orthodox care in the rural area.

CONCLUSIONS

Knowledge of VPDs was poor and multiple treatment sources were common among rural and urban women. Education is vital to improve immunization knowledge and health-seeking behavior in both areas.

Village-randomized clinical trial of home distribution of zinc for treatment of childhood diarrhea in rural Western kenya

Background

Zinc treatment shortens diarrhea episodes and can prevent future episodes. In rural Africa, most children with diarrhea are not brought to health facilities. In a village-randomized trial in rural Kenya, we assessed if zinc treatment might have a community-level preventive effect on diarrhea incidence if available at home versus only at health facilities.

Methods

We randomized 16 Kenyan villages (1,903 eligible children) to receive a 10-day course of zinc and two oral rehydration solution (ORS) sachets every two months at home and 17 villages (2,241 eligible children) to receive ORS at home, but zinc at the health–facility only. Children’s caretakers were educated in zinc/ORS use by village workers, both unblinded to intervention arm. We evaluated whether incidence of diarrhea and acute lower respiratory illness (ALRI) reported at biweekly home visits and presenting to clinic were lower in zinc villages, using poisson regression adjusting for baseline disease rates, distance to clinic, and children’s age.

Results

There were no differences between village groups in diarrhea incidence either reported at the home or presenting to clinic. In zinc villages (1,440 children analyzed), 61.2% of diarrheal episodes were treated with zinc, compared to 5.4% in comparison villages (1,584 children analyzed, p<0.0001). There were no differences in ORS use between zinc (59.6%) and comparison villages (58.8%). Among children with fever or cough without diarrhea, zinc use was low (<0.5%). There was a lower incidence of reported ALRI in zinc villages (adjusted RR 0.68, 95% CI 0.46–0.99), but not presenting at clinic.

Conclusions

In this study, home zinc use to treat diarrhea did not decrease disease rates in the community. However, with proper training, availability of zinc at home could lead to more episodes of pediatric diarrhea being treated with zinc in parts of rural Africa where healthcare utilization is low.

The recognition of and care seeking behaviour for childhood illness in developing countries: a systematic review

BACKGROUND

Pneumonia, diarrhoea, and malaria are among the leading causes of death in children. These deaths are largely preventable if appropriate care is sought early. This review aimed to determine the percentage of caregivers in low- and middle-income countries (LMICs) with a child less than 5 years who were able to recognise illness in their child and subsequently sought care from different types of healthcare providers.

METHODS AND FINDINGS

We conducted a systematic literature review of studies that reported recognition of, and/or care seeking for episodes of diarrhoea, pneumonia or malaria in LMICs. The review is registered with PROSPERO (registration number: CRD42011001654). Ninety-one studies met the inclusion criteria. Eighteen studies reported data on caregiver recognition of disease and seventy-seven studies on care seeking. The median sensitivity of recognition of diarrhoea, malaria and pneumonia was low (36.0%, 37.4%, and 45.8%, respectively). A median of 73.0% of caregivers sought care outside the home. Care seeking from community health workers (median: 5.4% for diarrhoea, 4.2% for pneumonia, and 1.3% for malaria) and the use of oral rehydration therapy (median: 34%) was low.

CONCLUSIONS

Given the importance of this topic to child survival programmes there are few published studies. Recognition of diarrhoea, malaria and pneumonia by caregivers is generally poor and represents a key factor to address in attempts to improve health care utilisation. In addition, considering that oral rehydration therapy has been widely recommended for over forty years, its use remains disappointingly low. Similarly, the reported levels of care seeking from community health workers in the included studies are low even though global action plans to address these illnesses promote community case management. Giving greater priority to research on care seeking could provide crucial evidence to inform child mortality programmes.

mHealth Series: mHealth project in Zhao County, rural China - Description of objectives, field site and methods

Background

We set up a collaboration between researchers in China and the UK that aimed to explore the use of mHealth in China. This is the first paper in a series of papers on a large mHealth project part of this collaboration. This paper included the aims and objectives of the mHealth project, our field site, and the detailed methods of two studies.

Field site

The field site for this mHealth project was Zhao County, which lies 280 km south of Beijing in Hebei Province, China.

Methods

We described the methodology of two studies: (i) a mixed methods study exploring factors influencing sample size calculations for mHealth–based health surveys and (ii) a cross–over study determining validity of an mHealth text messaging data collection tool. The first study used mixed methods, both quantitative and qualitative, including: (i) two surveys with caregivers of young children, (ii) interviews with caregivers, village doctors and participants of the cross–over study, and (iii) researchers’ views. We combined data from caregivers, village doctors and researchers to provide an in–depth understanding of factors influencing sample size calculations for mHealth–based health surveys. The second study, a cross–over study, used a randomised cross–over study design to compare the traditional face–to–face survey method to the new text messaging survey method. We assessed data equivalence (intrarater agreement), the amount of information in responses, reasons for giving different responses, the response rate, characteristics of non–responders, and the error rate.

Conclusions

This paper described the objectives, field site and methods of a large mHealth project part of a collaboration between researchers in China and the UK. The mixed methods study evaluating factors that influence sample size calculations could help future studies with estimating reliable sample sizes. The cross–over study comparing face–to–face and text message survey data collection could help future studies with developing their mHealth tools.

Comparison of the estimated cost-effectiveness of preventive and therapeutic zinc supplementation strategies for reducing child morbidity and mortality in sub-Saharan Africa

BACKGROUND

Zinc supplementation of young children in lower-income countries reduces morbidity from diarrhea and pneumonia and all-cause mortality, but the most cost-effective approach for distributing zinc supplements is unknown.

OBJECTIVE

To examine the potential impact of four possible strategies for delivering zinc supplements on disease prevention and deaths averted among children 6 to 59 months of age in sub-Saharan Africa.

METHODS

We analyzed different zinc supplementation strategies to assess their likely impact on morbidity and mortality of preschool children in sub-Saharan Africa and to estimate their possible costs.

RESULTS

Preventive zinc supplementation reduces diarrhea incidence by 27% among children 12 to 59 months of age, pneumonia incidence by 21% among children 6 to 59 months of age, and all-cause mortality by 18% among children 12 to 59 months of age. The likely average total program costs of zinc supplementation programs were estimated from the outlays of existing service delivery platforms, such as child health days, community-based nutrition programs, and clinic-based treatment of diarrhea, assuming different levels of coverage and target age ranges of children.

CONCLUSIONS

We found that the average total costs per life saved ranged from approximately US$462 to US$3,111, and the most cost-effective interventions were weekly or intermittent preventive zinc supplementation, because of the possibility of high coverage and fewer supplements required. Empirical data from zinc supplementation programs will be needed to confirm these estimates.
