'A child is also a teacher': exploring the potential for children as change agents in the context of a school-based WASH intervention in rural Eastern Zambia

Determinants of household safe drinking water practices in Kabul, Afghanistan: New insights from behavioural survey data

More than 2 billion people worldwide lack access to safe drinking water. Household water treatment (HWT) is an interim option for reducing the risk of water born disease. Understanding the factors that influence HWT behaviour is crucial for delivering successful interventions aimed at scaling relevant technologies, but the literature tends to emphasise psychological determinants with little consideration of socioeconomic and contextual factors. This article responds to this literature by using the COM-B model to examine the determinants of HWT practices through a comprehensive and context-sensitive behaviour definition. We informed this model through a cross-sectional survey design in which we collected data from 913 households in two peri‑urban neighbourhoods of Kabul, Afghanistan. Our findings from descriptive statistical and regression analysis highlight the importance of not only psychological but also socio-economic and contextual determinants of HWT behaviour: Especially the COM-B dimensions of reflective and automatic motivation, and physical opportunity - which are heavily influenced by local context and economic circumstances - had statistically significant associations with performing HWT. The practical significance of these dimensions was similarly pronounced. For example, an increase in the physical opportunity index by 0.1 units from an average value of 0.7 to 0.8 would be associated with a 7.7 percentage-point higher likelihood of HWT performance. These results suggest that the COM-B model can be utilised to systematically design interventions aimed at promoting HWT practices, while highlighting the need to broaden behavioural analyses of HWT and consider contextual factors to develop interventions that are tailored to the specific needs and obstacles of different communities.

A cluster-randomised controlled equivalence trial of the Surprise Soap handwashing intervention among older children living in a refugee settlement in Sudan

INTRODUCTION

Increasing handwashing with soap (HWWS) among older children in emergency settings can have a large public health impact, however, evidence on what works is limited. One promising approach is the 'Surprise Soap' intervention in which a novel soap with an embedded toy is delivered to children in a short, participatory household session that includes a glitter game and HWWS practice. Here, we evaluate this intervention against a standard intervention in a complex emergency setting.

METHODS

A cluster-randomised controlled equivalence trial was conducted in Naivasha refugee settlement, Sudan. Blinding was not possible. 203 randomly selected households, with at least one child aged 5-12, were randomised to receive the Surprise Soap intervention (n=101) or a standard intervention comprising a short household session with health messaging and plain soap distribution (n=102). The primary outcome was the proportion of prespecified potential HWWS events observed for children aged 5-12, accompanied by HWWS, at baseline, 4, 12 and 16 weeks post intervention delivery.

RESULTS

200 households were included in the analyses: 101 intervention and 99 control. No difference in intervention effectiveness was observed at any follow-up (4 weeks: adjusted rate ratio (RR) 1.2, 95% CI 0.8 to 1.7; 12 weeks: RR 0.8, 95% CI 0.5 to 1.1; 16 weeks: RR 1.1, 95% CI 0.8 to 1.5). However, we observed increased HWWS in both arms at 4 weeks (27 and 23 percentage point increase in the intervention and control arm, respectively) that was sustained at 16 weeks.

CONCLUSIONS

We find that the Surprise Soap intervention is no more effective at increasing older children's HWWS than a standard, household-level, health-based intervention in this complex humanitarian emergency. There appears to be no marginal benefit in terms of HWWS that would justify the additional cost of implementing the Surprise Soap intervention. Further trials that include a passive control arm are needed to determine the independent effects of each intervention and guide future intervention design.

Effect of a novel hygiene intervention on older children's handwashing in a humanitarian setting in Kahda district, Somalia: A cluster-randomised controlled equivalence trial

INTRODUCTION

Improving handwashing with soap (HWWS) among children in humanitarian emergencies has the potential to reduce the transmission of several important infectious diseases. However, there is limited evidence on which approaches are effective in increasing HWWS among children in humanitarian settings. One recent innovation - the "Surprise Soap" intervention - was shown to be successful in a small-scale efficacy trial in a humanitarian setting in Iraq. This intervention includes soap with embedded toys delivered through a short household session comprising a glitter game, instruction of how and when to wash hands, and HWWS practice. Whilst promising, this approach has not been evaluated at programmatic scale in a complex humanitarian setting.

METHODS

We conducted a cluster-randomised controlled equivalence trial of the Surprise Soap intervention in IDP camps in Kahda district, Somalia. Proportionate stratified random sampling was employed to recruit 200 households, with at least one child aged 5-12, across the camps. Eligible households were randomly allocated to receive the Surprise Soap intervention (n = 100) or an active comparator handwashing intervention in which plain soap was delivered in a short household session comprising standard health-based messaging and instruction of how and when to wash hands (n = 100). The primary outcome was the proportion of pre-specified occasions when HWWS was practiced by children aged 5-12 years, measured at baseline, 4-weeks, 12 weeks, and 16 weeks post invention delivery.

RESULTS

HWWS increased in both groups (by 48 percentage points in the intervention group and 51 percentage points in the control group, at the 4-week follow up), however, there was no evidence of a difference in HWWS between the groups at the 4-week (adjusted RR (aRR) = 1.0, 95% CI 0.9-1.1), 12-week (aRR = 1.1, 95% CI 0.9-1.3), or 16-week (aRR = 1.0, 95% CI 0.9-1.2) follow-up.

CONCLUSIONS

In this complex humanitarian setting, where soap availability and past exposure to handwashing promotion was low, it appears that well-designed, household-level targeted handwashing interventions that include soap provision can increase child HWWS and potentially reduce disease risk, but the Surprise Soap intervention offers no marginal benefit over a standard intervention that would justify the additional costs.

Nongovernmental Organization Practitioners' Perspectives on the Challenges and Solutions to Changing Handwashing Behavior in Older Children: A Qualitative Study

BACKGROUND

Increasing handwashing with soap (HWWS) among older children (aged 5-14 years) can achieve a substantial public health impact. However, HWWS interventions targeting older children have had mixed success. Recent research has attempted to quantitatively identify effective intervention techniques; however, success is likely also influenced by the wider context of implementation. We explore nongovernmental organization (NGO) practitioners' perspectives on the challenges and solutions to HWWS interventions targeting older children to enhance understanding of what is required, beyond intervention content, for them to be effective.

METHODS

We conducted in-depth, semistructured interviews in April-November 2020 with 25 practitioners employed across 11 NGOs and involved in HWWS interventions targeting older children in development and humanitarian settings. We used purposive and snowball sampling to recruit participants in roles at the global, national/regional, and local levels. Interviews were audio-recorded, transcribed, and thematically analyzed to identify challenges and solutions to HWWS interventions targeting older children. Results were organized according to program development cycle stages.

RESULTS

Twelve themes relating to perceived challenges emerged: (1) lack of prioritization, (2) funding inconsistency, (3) insufficient formative research, (4) demand on resources, (5) unengaging intervention content, (6) non-enabling physical environments, (7) availability of skilled implementers, (8) reaching out-of-school children, (9) community mistrust, (10) lack of coordination, (11) lack of evaluation rigor, and (12) failure to assign older children's HWWS as a primary outcome in evaluations of hygiene interventions. Recommended solutions were at the intervention, organization, and sector levels.

CONCLUSION

Intervention design and delivery are important for the success of HWWS interventions for older children, but contextual factors, such as the availability of human and material resources and the level of coordination within and beyond the NGO sector, should also be considered. NGOs need to prioritize HWWS promotion among older children and support programs accordingly.

Protocol: Implementation and evaluation of an adolescent-mediated intervention to improve glycemic control and diabetes self-management among Samoan adults

BACKGROUND

Diagnoses of Type 2 Diabetes in the United States have more than doubled in the last two decades. One minority group at disproportionate risk are Pacific Islanders who face numerous barriers to prevention and self-care. To address the need for prevention and treatment in this group, and building on the family-centered culture, we will pilot test an adolescent-mediated intervention designed to improve the glycemic control and self-care practices of a paired adult family member with diagnosed diabetes.

METHODS

We will conduct a randomized controlled trial in American Samoa among n = 160 dyads (adolescent without diabetes, adult with diabetes). Adolescents will receive either a six-month diabetes intervention or a leadership and life skills-focused control curriculum. Aside from research assessments we will have no contact with the adults in the dyad who will proceed with their usual care. To test our hypothesis that adolescents will be effective conduits of diabetes knowledge and will support their paired adult in the adoption of self-care strategies, our primary efficacy outcomes will be adult glycemic control and cardiovascular risk factors (BMI, blood pressure, waist circumference). Secondarily, since we believe exposure to the intervention may encourage positive behavior change in the adolescent themselves, we will measure the same outcomes in adolescents. Outcomes will be measured at baseline, after active intervention (six months post-randomization) and at 12-months post-randomization to examine maintenance effects. To determine potential for sustainability and scale up, we will examine intervention acceptability, feasibility, fidelity, reach, and cost.

DISCUSSION

This study will explore Samoan adolescents' ability to act as agents of familial health behavior change. Intervention success would produce a scalable program with potential for replication in other family-centered ethnic minority groups across the US who are the ideal beneficiaries of innovations to reduce chronic disease risk and eliminate health disparities.

Role of schools in community mobilisation to improve IYCF practices in 6-24-month-old tribal children in the Banswara district, India: findings from the qualitative PANChSHEEEL study

OBJECTIVE

India has been struggling with infant malnutrition for decades. There is a need to identify suitable platforms for community engagement to promote locally feasible, resource efficient Infant and Young Child Feeding (IYCF) interventions. This study aims to explore if and how schools could represent a site for community engagement in rural India, acting as innovation hubs to foster positive change in partnership with the Angawadi centres.

DESIGN

Five-phase formative study; A parallel mixed methods approach structured by a socioecological framework was used for data collection at individual, household and community levels. This paper focuses on the qualitative findings.

SETTING

This study was undertaken in nine villages within two blocks, 'Ghatol' and 'Kushalgarh', in the Banswara district of Rajasthan, India.

PARTICIPANTS

17 schools were identified. Interviews were conducted with local opinion leaders and representatives in the education sector, including principals, schoolteachers, block and district education officers. Across the nine study villages, information was gathered from 67 mothers, 58 paternal grandmothers using Focus Discussion Groups (FDGs) and 49 key respondents in Key Informant Interviews.

RESULTS

Schools were considered an important community resource. Challenges included limited parental participation and student absenteeism; however, several drivers and opportunities were identified, which may render schools a suitable intervention delivery site. Enrolment rates were high, with schools and associated staff encouraging parental involvement and student attendance. Existing initiatives, including the mid-day meal, play opportunities and education on health and hygiene, further highlight the potential reliability of schools as a platform for community mobilisation.

CONCLUSIONS

Schools have been shown to be functional platforms frequently visited and trusted by community members. With teachers and children as change agents, schools could represent a suitable setting for community mobilisation in future wider scale intervention studies. Expanding the supportive environment around schools will be essential to reinforce healthy IYCF practices in the long term.

Association between Handwashing Behavior and Infectious Diseases among Low-Income Community Children in Urban New Delhi, India: A Cross-Sectional Study

Diarrheal diseases and respiratory infections (RI) are two leading causes of childhood mortality in low and middle-income countries. Effective handwashing at critical time-points may mitigate these diseases. However, there is a lack of published data investigating this association in school-aged children in India. This study is part of a larger prospective handwashing intervention study in a low-income community in New Delhi, India examining the associations between handwashing behavior and diarrhea and RI in schoolchildren. This current study reports the findings of the baseline survey administered to 272 mother–child dyads. Children aged 8–12 years, and their mothers, were recruited from six schools. A baseline questionnaire was used to collect sociodemographic data, handwash behavior, and mother-reported recent diarrhea and RI incidence among the children. Handwashing before and after preparing food, after defecation, and after cleaning dishes significantly reduced the odds of diarrhea by over 70%, and of RI by over 56%. Using a clean cloth after handwashing lowered odds of diarrhea and RI by 72% and 63% respectively. Around 60% of the participants believed that handwashing could prevent diarrhea and RI in their children. There was a low prevalence of handwashing at critical time-points and a poor perception regarding handwashing benefits. To improve handwashing behavior, hygiene promotion programs need to understand what motivates and hinders handwashing in vulnerable populations.

The potential of school-based WASH programming to support children as agents of change in rural Zambian households

Background

Water, sanitation, and hygiene (WASH) interventions frequently assume that students who learn positive WASH behaviors will disseminate this information to their families. This is most prominent in school-based programs, which rely on students to act as “agents of change” to translate impact from school to home. However, there is little evidence to support or contradict this assumption.

Methods

We conducted a quasi-experimental, prospective cohort study in 12 schools in rural, southern Zambia to measure the impact of WASH UP!, a school-based WASH program designed by the creators of Sesame Street. WASH UP! is an educational program that uses stories and interactive games to teach students in grades 1–4 about healthy behaviors, such as washing hands and using the latrine. We completed in-person interviews with grade 1 and 4 students (N = 392 and 369, respectively), their teachers (N = 24) and caregivers (N = 729) using structured surveys containing both open- and closed-ended questions. We measured changes in knowledge and whether students reported sharing WASH-related messages learned in school with their caregivers at home.

Results

Student knowledge increased significantly, but primarily among students in grade 1. Overall rates of students reporting that they shared messages from the curriculum with their caregivers rose from 7 to 23% (p <  0.001). Students in grade 4 were 5.2 times as likely as those in grade 1 to report sharing a WASH-related message with their caregivers (ARR = 5.2, 95% C.I. = (2.3, 8.9); p <  0.001).

Conclusions

Although we measured only modest levels of student dissemination of WASH UP! messages from the school to the home, students in grade 4 showed significantly more promise as agents of change than those in grade 1. Future work should prioritize developing curricula that reflect the variability in needs, capabilities and support in the home and community among primary school students rather than a single approach for a wide range of ages and contexts.

Attitudes Toward COVID-19 Vaccines in Chinese Adolescents

Background: As COVID-19 vaccination programs are being implemented widely, it is important to examine the attitudes of adolescents toward the COVID-19 vaccine and its uptake. The aim of this study was to examine the acceptance of and attitudes toward COVID-19 vaccines, and their associated factors among adolescents in China.

Methods: This was a cross-sectional, observational study conducted between November 27, 2020 and March 12, 2021 using snowball sampling method. Basic sociodemographic characteristics, health-related information, severity of depressive and anxiety symptoms, and attitudes and behavior toward COVID-19 vaccines were assessed.

Results: Overall, 1,057 adolescents participated in this study, yielding a response rate of 89.3%. There were 799 (75.59%) [95% Confidence Interval (CI) 73.00–78.18%] adolescents who would accept future COVID-19 vaccination. Binary logistic regression analysis revealed that adolescents who previously heard about COVID-19 vaccines (P = 0.001, odds ratio (OR) = 1.90, 95%CI:1.32–2.74), who thought that COVID-19 vaccines could protect them from COVID-19 infection (P = 0.002, OR = 2.93, 95%CI: 1.49–5.70), and those who encouraged their family members and friends to get vaccinated (P < 0.001, OR = 12.19, 95%CI: 6.78–21.92) and who believed that vaccines are safe (P = 0.012, OR = 3.94, 95%CI: 1.36–11.44) were more likely to accept future COVID-19 vaccination. In addition, younger adolescents (P = 0.003, OR = 0.93, 95%CI: 0.89–0.98) were more likely to accept future COVID-19 vaccines than older adolescents.

Conclusions: In conclusion, Chinese adolescents appeared to have positive attitudes toward COVID-19 vaccines. It is important to increase public confidence and knowledge regarding the efficacy and safety of COVID-19 vaccines to maximize the success of vaccination programs.

Attributes of drinking water, sanitation, and hygiene associated with microbiological water quality of stored drinking water in rural schools in Mozambique and Uganda

Contaminated drinking water causes morbidity and mortality worldwide, especially in low- and middle-income countries. Drinking water quality has been studied extensively in household settings, but little research is available on drinking water quality in schools. School settings are of particular importance, because children are more susceptible than adults to a variety of diseases from contaminated drinking water. Many school water, sanitation and hygiene (WaSH) interventions have been studied for their efficacy to reduce diarrheal disease incidence, but few have evaluated drinking water quality, which reflects an important exposure pathway between WaSH services and health outcomes. Using school surveys developed from internationally established WaSH indicators and field microbiological water quality tests, we studied 374 rural schools in Mozambique and Uganda to understand the association between specific WaSH services and drinking water microbiological contamination, specifically testing most probable number (MPN) of Escherichia coli, an indicator of fecal contamination, per 100 mL. In Mozambique and Uganda, 71% and 83% respectively of rural schools had low risk drinking water quality (<1 E. coli/100 mL); thirteen percent and seven percent had very high-risk water quality (≥100 E. coli/100 mL). When accounting for all WaSH services studied, schools that used an improved-type water source had 0.22 times less E. coli in stored drinking water in Mozambique (95% CI: 0.07, 0.65) and 0.12 times less E. coli in Uganda (95% CI: 0.02, 0.80). In Mozambique, use of a water source within 30 minutes for travel and collection and the presence of water and soap/ash for handwashing were also significantly associated with less E. coli in drinking water. The findings of this study provide public health practitioners with implementable WaSH services to improve school drinking water quality, which has implications for the health, learning environment, and cognitive development of school children in rural Mozambique and Uganda.

Effectiveness of behaviour change techniques used in hand hygiene interventions targeting older children - A systematic review

BACKGROUND

Promoting good hand hygiene in older children is an important measure to reduce the burden of common diseases such as diarrhoea and acute respiratory infections. The evidence around what works to change this behaviour, however, is unclear.

OBJECTIVES

To aid future intervention design and effective use of resources, this review aims to identify the individual components used in hand hygiene interventions and assesses their contribution to intended behavioural change.

METHODS

We systematically searched seven databases for experimental studies evaluating hand hygiene interventions targeting children (age 5-12) and quantitively reporting hand hygiene behaviour. Interventions in each study were categorised as 'promising', or 'non-promising' according to whether they led to a positive change in the targeted behaviour. Behaviour change techniques (BCTs) were identified across interventions using a standard taxonomy and a novel promise ratio calculated for each (the ratio of promising to non-promising interventions featuring the BCT). 'Promising' BCTs were those with a promise ratio of ≥2. BCTs were ranked from most to least promising.

RESULTS

Our final analysis included 19 studies reporting 22 interventions across which 32 unique BCTs were identified. The most frequently used were 'demonstration of the behaviour', 'instruction on how to perform the behaviour' and 'adding objects to the environment'. Eight BCTs had a promise ratio of ≥2 and the five most promising were 'demonstration of the behaviour', 'information about social and environmental consequences', 'salience of consequences', 'adding objects to the environment', and 'instruction on how to perform the behaviour'.

CONCLUSIONS

Our findings suggest that hand hygiene interventions targeting older children should employ a combination of promising BCTs that ensure children understand the behaviour and the consequences of their hand hygiene habits, appropriate hardware is available, and social support is provided. Researchers are encouraged to consistently and transparently describe evaluated interventions to allow promising components to be identified and replicated.

Differences in Basic Life Support Knowledge Between Junior Medical Students and Lay People: Web-Based Questionnaire Study

BACKGROUND

Early cardiopulmonary resuscitation and prompt defibrillation markedly increase the survival rate in the event of out-of-hospital cardiac arrest (OHCA). As future health care professionals, medical students should be trained to efficiently manage an unexpectedly encountered OHCA.

OBJECTIVE

Our aim was to assess basic life support (BLS) knowledge in junior medical students at the University of Geneva Faculty of Medicine (UGFM) and to compare it with that of the general population.

METHODS

Junior UGFM students and lay people who had registered for BLS classes given by a Red Cross-affiliated center were sent invitation links to complete a web-based questionnaire. The primary outcome was the between-group difference in a 10-question score regarding cardiopulmonary resuscitation knowledge. Secondary outcomes were the differences in the rate of correct answers for each individual question, the level of self-assessed confidence in the ability to perform resuscitation, and a 6-question score, "essential BLS knowledge," which only contains key elements of the chain of survival. Continuous variables were first analyzed using the Student t test, then by multivariable linear regression. Fisher exact test was used for between-groups comparison of binary variables.

RESULTS

The mean score was higher in medical students than in lay people for both the 10-question score (mean 5.8, SD 1.7 vs mean 4.2, SD 1.7; P<.001) and 6-question score (mean 3.0, SD 1.1 vs mean 2.0, SD 1.0; P<.001). Participants who were younger or already trained scored consistently better. Although the phone number of the emergency medical dispatch center was well known in both groups (medical students, 75/80, 94% vs lay people, 51/62, 82%; P=.06), most participants were unable to identify the criteria used to recognize OHCA, and almost none were able to correctly reorganize the BLS sequence. Medical students felt more confident than lay people in their ability to perform resuscitation (mean 4.7, SD 2.2 vs mean 3.1, SD 2.1; P<.001). Female gender and older age were associated with lower confidence, while participants who had already attended a BLS course prior to taking the questionnaire felt more confident.

CONCLUSIONS

Although junior medical students were more knowledgeable than lay people regarding BLS procedures, the proportion of correct answers was low in both groups, and changes in BLS education policy should be considered.

Participation of children in school health in Japan

BACKGROUND

The importance of promoting child participation in school health has been emphasized internationally. This study examined ways in which Japan's school health system involves children, and factors enabling child participation in this system. It also suggests strategies to promote child participation in school health in developing countries.

METHODS

We conducted a document review to clarify the importance of, and recent trends in, child participation in school health. We summarized the system of child participation in school health in Japan and examined factors enabling child participation.

RESULTS

We identified the following four factors that enable child participation in school health in Japan: (i) having an explicit legal basis for participatory activities at the national level; (ii) having clear notification, in relevant administrative documents at the prefectural and municipal levels, of the necessity for children's voluntary participation; (iii) establishing a system for teachers to provide support for participatory activities at the school level, and (iv) having a shared understanding among stakeholders about the pedagogical importance of participatory activities in school health.

CONCLUSIONS

To promote child participation in school health activities in developing countries, it is necessary to describe clearly the importance, benefits, impacts, and purposes of child participation in relevant legal and administrative documents at relevant administrative levels. Schools should also ensure that stakeholders have a common understanding of the educational benefits of child participation considering the cultural context of each country. It is helpful to conduct appropriate training for teachers to enable them to facilitate child participation.

Adolescents as Agents of Parental Healthy Lifestyle Behavior Change: COPE Healthy Lifestyles TEEN Program

INTRODUCTION

Obesity is a leading health crisis around the world. An intervention strategy scarcely utilized for behavior change is that of a child as change agent. The purpose of this study was to describe the impact of teens reviewing newsletters from a healthy lifestyle intervention with their parents.

METHOD

Evaluation data from a randomized controlled trial, COPE Healthy Lifestyle TEEN Program, was analyzed. A descriptive study was conducted of parents' and teens' lifestyle behaviors as reported by parents.

RESULTS

One hundred sixty-nine parents completed evaluations. Two thirds of parents reported changing a behavior as a result of the program. Nearly three quarters of parents reported behavior changes in their teens. Over 90% reported they would recommend this or a similar program.

DISCUSSION

The obesity epidemic shows no signs of reversal, and hence multiple approaches to impact healthy lifestyles are urgent. Including children as a change agent is a potential target for interventions addressing obesity.

Use, adoption, and effectiveness of tippy-tap handwashing station in promoting hand hygiene practices in resource-limited settings: a systematic review

BACKGROUND

Tippy-taps are locally made devices for washing hands with running water. They are simple and low-cost, enabling technology that provides adequate water sources, handwashing stations and motivation for people to prioritise handwashing. This systematic review aimed to establish the use, benefits, adoption and effectiveness of enabling technology; tippy-tap handwashing station, in resource-limited settings.

METHODS

We systematically searched for articles in the PubMed, EMBASE, PsycINFO, AMED, CINAHL, DOAJ and Google Scholar databases guided by the acceptable best practice developed by the PROSPERO and COCHRANE for systematic search and selection of articles. Search terms such as tippy-taps, enabling technology, hand-washing station, hand-washing behaviour, diarrhoea, respiratory infection, increase handwashing behaviour were used. In addition, a PRISMA flow diagram was used to elaborate on the number of articles retrieved, retained, excluded and reasons for every action. Studies that used tippy-tap hand washing station as a handwashing facility regardless of the design were included in this review. A mixed method appraisal tool was used to appraise studies.

RESULTS

Twenty articles met the eligibility criteria. The use of tippy-taps for handwashing by household members or school children was reported by authors of 16 studies, and it ranged from 2.7 to 80%. The availability of tippy-taps increased handwashing and use of soap among participants. Furthermore, the majority of people who were oriented to tippy-taps or recruited to tippy-tap studies built their tippy-tap stations even after the promotional activities or programs had ended. In one study, tippy-taps were reported by participant to be effective in preventing episodes of stomach pain among participants.

CONCLUSION

Tippy-tap handwashing station could help in promoting handwashing practice in resource constraint settings. Future studies are needed to evaluate the effectiveness of tippy-tap hand washing station on preventing water and hygiene-related infections.

Quantitative Microbial Risk Assessment of Drinking Water Quality to Predict the Risk of Waterborne Diseases in Primary-School Children

Primary-school children in low- and middle-income countries are often deprived of microbiologically safe water and sanitation, often resulting in a high prevalence of gastrointestinal diseases and poor school performance. We used Quantitative Microbial Risk Assessment (QMRA) to predict the probability of infection in schoolchildren due to consumption of unsafe school water. A multistage random-sampling technique was used to randomly select 425 primary schools from ten districts of Sindh, Pakistan, to produce a representative sample of the province. We characterized water supplies in selected schools. Microbiological testing of water resulted in inputs for the QMRA model, to estimate the risks of infections to schoolchildren. Groundwater (62%) and surface water (38%) were identified as two major sources of drinking water in the selected schools, presenting varying degrees of health risks. Around half of the drinking-water samples were contaminated with Escherichia coli (49%), Shigella spp. (63%), Salmonella spp. (53%), and Vibrio cholerae (49%). Southern Sindh was found to have the highest risk of infection and illness from Campylobacter and Rotavirus. Central and Northern Sindh had a comparatively lower risk of waterborne diseases. Schoolchildren of Karachi were estimated to have the highest probability of illness per year, due to Campylobacter (70%) and Rotavirus (22.6%). Pearson correlation was run to assess the relationship between selected pathogens. V. cholerae was correlated with Salmonella spp., Campylobacter, Rotavirus, and Salmonella spp. Overall, the risk of illness due to the bacterial infection (E. coli, Salmonella spp., V. cholerae, Shigella, and Campylobacter) was high. There is a dire need for management plans in the schools of Sindh, to halt the progression of waterborne diseases in school-going children.

Impact of a teacher-led school handwashing program on children's handwashing with soap at school and home in Bihar, India

Handwashing with soap is an important preventive health behavior, and yet promoting this behavior has proven challenging. We report the results of a program that trained teachers to deliver a handwashing with soap behavior change program to children in primary schools in Bihar, India. Ten intervention schools selected along with ten nearby control schools, and intervention schools received the “School of Five” program promoting handwashing with soap using interactive stories, games, and songs, behavioral diaries to encourage habit formation, and public commitment. Households with children aged 8–13 attending the nearby school were enrolled in the study. Handwashing with soap was measured using sticker diaries before eating and after defecation 4 weeks after the intervention was completed. Children in the treatment reported 15.1% more handwashing with soap on key occasions (35.2%) than those in the control group (20.1%) (RR: 1.77, CI: (1.22, 2.58), p = .003). There was no evidence that handwashing with soap after defecation was higher in the treatment group than the control group (RR: 1.18, CI: (0.88, 1.57), p = .265), but there was strong evidence that handwashing with soap was greater in the treatment than in the control before eating (RR: 2.68, 95% CI: (1.43, 5.03), p = .002). Rates of handwashing increased both at home (RR: 1.63, CI: 1.14, 2.32), p = .007) and at school (RR: 4.76, 95% CI: (1.65, 17.9), p = .004), though the impact on handwashing with soap at key occasions in schools was much higher than at home. Promoting handwashing with soap through teachers in schools may be an effective way to achieve behavior change at scale.

Designing integrated interventions to improve nutrition and WASH behaviors in Kenya

Background

Child stunting, an indicator of chronic malnutrition, is a global public health problem. Malnutrition during pregnancy and the first 2 years of life undermines the survival, growth, and development of children. Exposure to fecal pathogens vis-à-vis inadequate water, sanitation, and hygiene (WASH) has been implicated in the etiology of child stunting, highlighting the need to integrate WASH with nutrition-sensitive interventions to comprehensively address this complex problem. The aim of this study was to describe a systematic, theoretically informed approach (that drew from the Starr and Fornoff approach to the Theory of Change development and the Behavior Change Wheel approach) to design a multi-component and integrated social and behavior change intervention to improve WASH and nutrition-related behaviors in western Kenya.

Methods

This intervention was developed to be integrated into an existing project that utilized the care group model and aimed to create a culture of care and support for HIV/AIDS-affected children under two and their caregivers and was executed by local partners. We tested the newly created intervention packages in user-testing trials using an adapted Trials of Improved Practices approach to pilot acceptability and feasibility.

Results

Using authentic stakeholder engagement and relevant theories, we conducted an 8-step process: (1) conduct mixed methods formative research, (2) prioritize target behaviors, (3) use causal analysis to create problem trees, (4) develop solution trees and articulate assumptions and rationales for change, (5) link solution trees to intervention functions, (6) develop the intervention plan, (7) create the intervention packages, and (8) test and refine the intervention packages.

Conclusions

This study highlights the need to take a multi-sectorial, integrated approach that integrates contextually relevant behavior change theories with the experiential knowledge gleaned from stakeholders into the design of interventions that seek to reduce child stunting. This process resulted in the creation of intervention packages that grouped behaviors thematically to be most relevant and responsive to the population context. This work has the potential to make important contributions towards achievement of the United Nations’ sustainable development goals.

Adapting Translational Research Methods to Water, Sanitation, and Hygiene

Translational research applies scientific techniques to achieve practical outcomes, connecting pure research and pure practice. Many translational research types have arisen since the mid-1900s, reflecting the need to better integrate scientific advancement with policy and practice. Water, sanitation, and hygiene (WaSH) development efforts have aimed to reduce morbidity and mortality and improve service delivery; thus, associated research has a strong orientation toward applied studies that use diverse methods to support decision-making. Drawing from knowledge that emerged to support other professional fields, such as manufacturing and clinical healthcare, we characterize different types of translational research and clarify nomenclature and principles. We describe study approaches relevant to translational research questions, and offer overarching recommendations, specific examples, and resources for further study as practical advice to professionals who seek to apply translational methods to WaSH problems. To enhance collective outcomes, professionals should mindfully align projects within the translational spectrum. We further recommend overarching good practices such as documenting intervention adaptations, overtly considering contextual factors, and better distinguishing efficacy from effectiveness research by replicating studies in different contexts. By consciously improving the compatibility and linkages between WaSH science and practice, this guide can accelerate urgently needed progress toward global development goals.

Educating children and adolescents about vaccines: a review of current literature

INTRODUCTION

Until recently, research on vaccine hesitancy has focused primarily on parent populations. Although adolescent knowledge and views are gaining momentum within the literature, particularly with regards to the human papillomavirus and influenza, children remain a virtually unstudied population with regards to vaccine hesitancy.

AREAS COVERED

This review focuses on the lack of literature in this area and argues for more vaccine hesitancy research involving child and adolescent populations. It also outlines special issues to consider when framing health promotion messages for children and adolescents. Finally, we explore the use of new and existing technologies as delivery mechanisms for education on vaccines and immunizations in populations of children and adolescents.

EXPERT COMMENTARY

Children undergo cognitive development and experiences with vaccines (e.g. pain or education) have the potential to create future attitudes toward vaccines. This can influence future vaccine behaviour, including their participation in decision-making around adolescent vaccines, their decisions to vaccinate themselves when they are adults, and their decisions to vaccinate their own children. Interventions aimed at children, such as education, can create positive attitudes toward vaccines. These can also potentially influence parental attitudes toward vaccines as children convey this knowledge to them. Both of these impacts require further study.

Pilot of an Elementary School Cough Etiquette Intervention: Acceptability, Feasibility, and Potential for Sustainability

Schools convene many people together for a prolonged time, facilitating spread of respiratory pathogens and amplifying epidemics. Crowded Bangladeshi schools lack the infrastructure to support optimal cough etiquette behaviors. We collected formative data on current practices from four elementary schools, and developed and piloted a low-cost cough etiquette intervention, promoting coughing and sneezing into upper sleeves at four additional schools. We trained teachers to lead behavior change sessions during regular hygiene classes for 4 weeks. We evaluated intervention acceptability, feasibility, and potential for sustainability at 1 month and at 14 months after the intervention commenced. At baseline, among 63 observed students, 58 (92%) coughed/sneezed into open air, five (8%) covered coughs/sneezes with their hands, which were not subsequently washed with soap and water as they judged this infeasible. After 4 weeks, among 70 observed students, 27 (39%) coughed/sneezed into upper sleeves, 33 (47%) into open air, and 10 (12%) covered with hands. After 14 months, among 230 observed students, 13 (6%) used upper sleeves, 154 (67%) coughed/sneezed into open air, and 59 (26%) covered with hands. Students reported that coughing/sneezing into upper sleeves was simple and protected them and their classmates from germs. This school-based intervention was acceptable and feasible, and resulted in short-term reductions in coughing/sneezing into open air, but these habits of comparatively new behavior were not sustained as teachers ceased behavior change session delivery. Strategies to support longer-term adoption of habits should be considered.

Children as agents of change in combatting antibiotic resistance

Antibiotic resistance is a worldwide problem and changes are needed in the way antibiotics are used. The value of engaging children as key contributors in health care campaigns to increase the appropriate use of antibiotics has not been fully recognized. Little is known about how to design educational materials for children in order to enable them to be agents of change in their communities. Science education needs to improve the way it engages children so as to give them the tools needed to make responsible decisions on antibiotic use.
