Recommendations for hand hygiene in community settings: a scoping review of current international guidelines. BMJ Open 2023; 13:e068887. [PMID: 37344109 PMCID: PMC10314431 DOI: 10.1136/bmjopen-2022-068887] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Accepted: 03/17/2023] [Indexed: 06/23/2023] Open
Abstract
BACKGROUND Hand hygiene is an important measure to prevent disease transmission. OBJECTIVE To summarise current international guideline recommendations for hand hygiene in community settings and to assess to what extent they are consistent and evidence based. ELIGIBILITY CRITERIA We included international guidelines with one or more recommendations on hand hygiene in community settings-categorised as domestic, public or institutional-published by international organisations, in English or French, between 1 January 1990 and 15 November 2021. DATA SOURCES To identify relevant guidelines, we searched the WHO Institutional Repository for Information Sharing Database, Google, websites of international organisations, and contacted expert organisations and individuals. CHARTING METHODS Recommendations were mapped to four areas related to hand hygiene: (1) effective hand hygiene; (2) minimum requirements; (3) behaviour change and (4) government measures. Recommendations were assessed for consistency, concordance and whether supported by evidence. RESULTS We identified 51 guidelines containing 923 recommendations published between 1999 and 2021 by multilateral agencies and international non-governmental organisations. Handwashing with soap is consistently recommended as the preferred method for hand hygiene across all community settings. Most guidelines specifically recommend handwashing with plain soap and running water for at least 20 s; single-use paper towels for hand drying; and alcohol-based hand rub (ABHR) as a complement or alternative to handwashing. There are inconsistent and discordant recommendations for water quality for handwashing, affordable and effective alternatives to soap and ABHR, and the design of handwashing stations. There are gaps in recommendations on soap and water quantity, behaviour change approaches and government measures required for effective hand hygiene. Less than 10% of recommendations are supported by any cited evidence. CONCLUSION While current international guidelines consistently recommend handwashing with soap across community settings, there remain gaps in recommendations where clear evidence-based guidance might support more effective policy and investment.

PLoS One 2022; 17:e0274069. [PMID: 36083872 PMCID: PMC9462565 DOI: 10.1371/journal.pone.0274069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Accepted: 08/21/2022] [Indexed: 11/25/2022] Open
Abstract
Child feces are an important source of fecal exposure in household environments. Typically, one of two behaviors is necessary to mitigate this risk: either caregivers dispose of their children’s feces into a latrine or children learn how to use a latrine. Although past studies have examined factors associated with these two behaviors collectively (i.e. “safe disposal”), there is a need to separately analyze these distinctive practices to better inform programming. This study aims to quantitatively examine contextual and psychosocial factors influencing caregiver safe disposal and, separately, child latrine training. We surveyed 791 primary female caregivers, who reported on 906 children <5 years old, across 74 villages in rural Odisha, India. At their last defecation event, 38% of children used the latrine and another 10% had their feces safely disposed of into the latrine. Since caregiver safe disposal was rare, we instead assessed safe disposal intention. We used linear regression and multilevel mixed effects models to examine contextual and psychosocial factors. For contextual factors, we found caregivers had stronger safe disposal intention when they came from wealthier households and had greater informational support, but weaker intention when their latrine was near the household. Caregivers more intensely practiced latrine training with their child when they themselves used the latrine for defecation, the latrine was fully intact, and they had greater instrumental support. For psychosocial factors, caregivers had stronger safe disposal intention when their households expected them to practice safe disposal, they felt strongly committed to the behavior, and had a plan for what to do when faced with a water shortage. Caregivers more intensely taught their child how to use the latrine when they believed their child was at risk of becoming sick if they practiced open defecation (OD); viewed child OD as unbeneficial; liked teaching their child; personally felt it was important for the child’s father to help; felt confident in their ability to teach their child; and had greater action control over their training practice. Interestingly, caregivers put less effort into latrine training when they felt more concerned for their child’s safety when the child defecated outside. These findings underscore the critical need to separately assess unique child feces management (CFM) practices and also provide a road map for practitioners on the types of behavior change strategies to consider in their CFM programming.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19169823. [PMID: 36011456 PMCID: PMC9407852 DOI: 10.3390/ijerph19169823] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Revised: 07/31/2022] [Accepted: 08/03/2022] [Indexed: 06/02/2023]
Abstract
Improving hygiene practices is considered to be the single most cost-effective means of reducing the global health burden of infectious diseases. Hygiene promotion and disease prevention interventions often portray and promote "hygiene" from a biomedical perspective, which may not be optimally effective for achieving their goal of changing people's behaviors. This study aimed to educe the meaning of hygiene for the residents of a low-income community in Bangladesh and how that meaning shapes their personal hygiene practices. We conducted this study in the Tongi township in Dhaka, Bangladesh, from September 2014 to June 2016. The research team purposively selected 24 households. The team conducted day-long observations using the participant observation approach and in-depth interviews with specific members of the 24 households. The concept of "hygiene" had two separate meanings to the study participants: cleanliness and holiness. The participants reported that cleanliness was required to remove odors, grease, hot spices and dirt. The motivation for cleanliness was to feel fresh, avoid heavy feelings, feel light and feel comfortable. To maintain the holiness of the body, bathing and ablution needed to be performed following particular religious rules/rituals. The motivation of holiness was derived from their accountability to God. The participants also reported that the cleansing processes and methods for the body and the home for cleanliness reasons were also different from those for holiness reasons. The notion of "hygiene" was multidimensional for the residents of the low-income urban community in Bangladesh. Our study participants did not explicitly conceptualize a notion of hygiene that was based on the germ theory of diseases but rather a notion that was based on individual physical comfort and cultural belief systems. Future studies on the prevention of hygiene-related diseases should combine and link the biomedical aspect to religious and cultural rituals to promote improved hygiene practices.

Costs of hand hygiene for all in household settings: estimating the price tag for the 46 least developed countries. BMJ Glob Health 2021; 6:e007361. [PMID: 34916276 PMCID: PMC8679104 DOI: 10.1136/bmjgh-2021-007361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 11/19/2021] [Indexed: 11/24/2022] Open
Abstract
INTRODUCTION Domestic hand hygiene could prevent over 500 000 attributable deaths per year, but 6 in 10 people in least developed countries (LDCs) do not have a handwashing facility (HWF) with soap and water available at home. We estimated the economic costs of universal access to basic hand hygiene services in household settings in 46 LDCs. METHODS Our model combines quantities of households with no HWF and prices of promotion campaigns, HWFs, soap and water. For quantities, we used estimates from the WHO/UNICEF Joint Monitoring Programme. For prices, we collated data from recent impact evaluations and electronic searches. Accounting for inflation and purchasing power, we calculated costs over 2021-2030, and estimated total cost probabilistically using Monte Carlo simulation. RESULTS An estimated US$12.2-US$15.3 billion over 10 years is needed for universal hand hygiene in household settings in 46 LDCs. The average annual cost of hand hygiene promotion is US$334 million (24% of annual total), with a further US$233 million for 'top-up' promotion (17%). Together, these promotion costs represent US$0.47 annually per head of LDC population. The annual cost of HWFs, a purpose-built drum with tap and stand, is US$174 million (13%). The annual cost of soap is US$497 million (36%) and water US$127 million (9%). CONCLUSION The annual cost of behavioural change promotion to those with no HWF represents 4.7% of median government health expenditure in LDCs, and 1% of their annual aid receipts. These costs could be covered by mobilising resources from across government and partners, and could be reduced by harnessing economies of scale and integrating hand hygiene with other behavioural change campaigns where appropriate. Innovation is required to make soap more affordable and available for the poorest households.

Abstract
RATIONALE Many behaviours relevant to public health are part of everyday routines. However, few tools exist to study such behaviours. Here we re-introduce the behaviour setting, an ecological psychological concept developed in the 1950s, as an approach to the study of routine behaviour. The setting concept bridges theoretical and applied approaches in sociology, psychology and social practice; its components include stage, infrastructure, props, roles, norms, competencies, objectives and resultant routines. METHODS We applied settings theory to health-related water use behaviour in rural Nigeria. We captured the dimensions of water use behaviour settings in 23 households at varying distances from newly-introduced kiosks selling purified water. RESULTS We found that routines concerning drinking, laundering, dish washing and handwashing were stable in their settings, varying little between households or by type of water source. Hygiene routines were suboptimal but drinking water was carefully segregated. The majority of water use behaviour was governed, not by an immediate desire to maximise health, but by long-established routines embedded in the social, technical and physical environment. Water kiosks are making only marginal improvements to the quantity and quality of water being used in homes. CONCLUSIONS Improving public health will require the disruption of settings, for example, through bringing water infrastructure directly to the home, through the sale of new props that facilitate hygienic routines, or in the disruption of gender roles via the promotion of new norms. Settings are an ecologically valid, meso-level theoretical approach that link social and techno-physical environmental factors to behaviour. They provide a comprehensive framework within which to judge avenues for changing routine behaviours. The behaviour settings tool we developed was easy to use, provided a systematic means of capturing the determinants of routine behaviour, and the findings offered insight into methods for disrupting such behaviour.

Abstract
BACKGROUND Clubfoot is a common congenital musculoskeletal disorder that causes mobility impairment. There is a lack of trained mid-level personnel to provide clubfoot treatment in Africa and there is no standard training course. This prospective study describes the collaborative and participatory approach to the development of a training course for the treatment of clubfoot in children in resource constrained settings. METHODS We used a systems approach to evaluate the development of the training course. Inputs: The research strategy included a review of context and available training materials, and the collection of data on current training practices. Semi-structured interviews were conducted with seven expert clubfoot trainers. A survey of 32 international and regional trainers was undertaken to inform practical issues. The data were used to develop a framework for training with advice from two technical groups, consisting of regional and international stakeholders and experts. PROCESS A consensus approach was undertaken during workshops, meetings and the sharing of documents. The design process for the training materials took twenty-four months and was iterative. The training materials were piloted nine times between September 2015 and February 2017. Processes and materials were reviewed and adapted according to feedback after each pilot. RESULTS Fifty-one regional trainers from Africa (18 countries), 21 international experts (11 countries), 113 local providers of clubfoot treatment (Ethiopia, Rwanda and Kenya) and local organising teams were involved in developing the curriculum and pilot testing. The diversity of the two technical advisory groups allowed a wide range of contributions to the collaboration. Output: The resulting curriculum and content comprised a two day basic training and a two day advanced course. The basic course utilised adult learning techniques for training novice providers in the treatment of idiopathic clubfoot in children under two years old. The advanced course builds on these principles. CONCLUSION Formative research that included mixed methods (both qualitative and quantitative) was important in the development of an appropriate training course. The process documentation from this study provides useful information to assist planning of medical training programmes and may serve as a model for the development of other courses.

Abstract
We sought to develop a water, sanitation, and hygiene (WASH) intervention to minimize fecal-oral transmission among children aged 0-18 months in the Sanitation Hygiene Infant Nutrition Efficacy (SHINE) trial. We undertook 4 phases of formative research, comprising in-depth interviews, focus group discussions, behavior trials, and a combination of observations and microbiological sampling methods. The resulting WASH intervention comprises material inputs and behavior change communication to promote stool disposal, handwashing with soap, water treatment, protected exploratory play, and hygienic infant feeding. Nurture and disgust were found to be key motivators, and are used as emotional triggers. The concept of a safe play space for young children was particularly novel, and families were eager to implement this after learning about the risks of unprotected exploratory play. An iterative process of formative research was essential to create a sequenced and integrated longitudinal intervention for a SHINE household as it expects (during pregnancy) and then cares for a new child.

Abstract
Household water treatment (HWT) can improve drinking water quality and prevent disease, if used correctly and consistently. While international monitoring suggests that 1.8 billion people practice HWT, these estimates are based on household surveys that may overstate the level of consistent use and do not address microbiological effectiveness. We sought to examine how HWT is practiced among households identified as HWT users according to international monitoring standards. Case studies were conducted in urban and rural Zambia. After a baseline survey (urban: 203 households, rural: 276 households) to identify HWT users, 95 urban and 82 rural households were followed up for 6 weeks. Consistency of HWT reporting was low; only 72.6% of urban and 50.0% of rural households reported to be HWT users in the subsequent visit. Similarly, availability of treated water was low, only 23.3% and 4.2% of urban and rural households, respectively, had treated water on all visits. Drinking water was significantly worse than source water in both settings. Only 19.6% of urban and 2.4% of rural households had drinking water free of thermotolerant coliforms on all visits. Our findings raise questions about the value of the data gathered through the international monitoring of HWT practices as predictors of water quality in the home.

Abstract
RATIONALE AND OBJECTIVE Access to and use of hygienic shared sanitation facilities is fundamental in reducing the high risk of diseases such as diarrhoea and respiratory infections. We evaluated the effectiveness of group discussions and commitment in improving the cleaning behaviour of shared sanitation users in three urban slums in Kampala, Uganda. The study follows the risk, attitudes, norms, abilities and self-regulation (RANAS) model of behaviour change and some factors of the social dilemma theory. METHODS A pre-versus post-intervention survey was conducted in three slums of Kampala, Uganda, between December 2012 and September 2013. From the pre-intervention findings, users of dirty sanitation facilities were randomly assigned to discussions, discussions + commitment and control interventions. The interventions were implemented for 3 months with the aim of improving cleaning behaviour. This paper provides an analysis of 119 respondents who belonged to the intervention discussion-only (n = 38), discussions + commitment (n = 41) and the control (no intervention, n = 40) groups. RESULTS Compared to the control, discussions and discussions + commitment significantly improved shared toilet users' cleaning behaviour. The rate of improvement was observed through behavioural determinants such as cleaning obligation, cleaning ease, cleaning approval and affective beliefs. CONCLUSION Our study findings show that group discussions and commitment interventions derived from RANAS model of behaviour change are effective in improving the shared sanitation users' cleaning behaviour.

Abstract
Improved access to water is a key factor in reducing diarrhoeal diseases, a leading cause of death among children in sub-Saharan Africa. In terms of water access, sub-Saharan African cities are some of the worst off in the world, with 20% of populations supplied by an unimproved water source. This situation is even worse in informal settlement areas. Using cross-sectional data on access to water from a survey implemented in three informal neighbourhoods of the Ouagadougou Health and Demographic Surveillance System, logistic regressions are modelled to test the effect of different modalities of access to water on childhood diarrhoea. Our results show that the prevalence of diarrhoea in children is high: one-third of households with a child under 10 experienced an episode of childhood diarrhoea during the 2 weeks preceding the survey, even though 91% of the households surveyed have access to an improved water source. The results show that efforts to reduce childhood morbidity would be greatly enhanced by strengthening piped water access in informal settlement areas in Africa. In addition, this study confirms that, beyond the single measure of the main access to water, accurate variables that assess the accessibility to water are needed.

Abstract
BACKGROUND Household water treatment (HWT) can improve drinking water quality and prevent disease if used correctly and consistently by vulnerable populations. Over 1.1 billion people report treating their water prior to drinking it. These estimates, however, are based on responses to household surveys that may exaggerate the consistency and microbiological performance of the practice-key factors for reducing pathogen exposure and achieving health benefits. The objective of this study was to examine how HWT practices are actually performed by households identified as HWT users, according to international monitoring standards. METHODS AND FINDINGS We conducted a 6-month case study in urban (n = 117 households) and rural (n = 115 households) Peru, a country in which 82.8% of households report treating their water at home. We used direct observation, in-depth interviews, surveys, spot-checks, and water sampling to assess water treatment practices among households that claimed to treat their drinking water at home. While consistency of reported practices was high in both urban (94.8%) and rural (85.3%) settings, availability of treated water (based on self-report) at time of collection was low, with 67.1% and 23.0% of urban and rural households having treated water at all three sampling visits. Self-reported consumption of untreated water in the home among adults and children <5 was common and this was corroborated during home observations. Drinking water of self-reported users was significantly better than source water in the urban setting and negligible but significantly better in the rural setting. However, only 46.3% and 31.6% of households had drinking water <1 CFU/100 mL at all follow-up visits. CONCLUSIONS Our results raise questions about the usefulness of current international monitoring of HWT practices and their usefulness as a proxy indicator for drinking water quality. The lack of consistency and sub-optimal microbiological effectiveness also raises questions about the potential of HWT to prevent waterborne diseases.

Abstract
Background This article reports on formative research into the context and practice of handwashing with soap by new mothers, which can substantially impact child morbidity and mortality. New mothers are an important target group for handwashing interventions: they are considered particularly susceptible to behaviour change and their actions can directly affect a child’s health. Methods Twenty-seven mothers of infants (including neonates) from urban and rural sub-districts of Serang were recruited and filmed over a period of eight hours. Video footage was used to identify handwashing occasions and to understand the context in which behaviour took place. Each woman was subsequently interviewed. Results Handwashing with soap was found to be infrequent, typically occurring after eating, cooking and household chores or after cleaning a child’s bottom. Handwashing before preparing food or eating was rare. Pre-pregnancy routines were reported to have been disrupted. Advice on child care comes from many sources, particularly the midwife and new child’s grandmother. Conclusions Developing interventions to change perceptions and practice of handwashing would seed an important behaviour and could save lives. New mothers represent an ideal target group for such an intervention. We suggest that interventions target an increase in handwashing with soap after contact with own and a baby’s faecal matter as part of the post-defecation hygiene routines. As the child’s grandmother is an authoritative source of information about parenting, interventions focussed on improving newborn care could target grandmothers as well as midwives.

Abstract
Remotely reporting electronic sensors offer the potential to reduce bias in monitoring use of environmental health interventions. In the context of a five-month randomized controlled trial of household water filters and improved cookstoves in rural Rwanda, we collected data from intervention households on product compliance using (i) monthly surveys and direct observations by community health workers and environmental health officers, and (ii) sensor-equipped filters and cookstoves deployed for about two weeks in each household. The adoption rate interpreted by the sensors varied from the household reporting: 90.5% of households reported primarily using the intervention stove, while the sensors interpreted 73.2% use, and 96.5% of households reported using the intervention filter regularly, while the sensors interpreted no more than 90.2%. The sensor-collected data estimated use to be lower than conventionally collected data both for water filters (approximately 36% less water volume per day) and cookstoves (approximately 40% fewer uses per week). An evaluation of intrahousehold consistency in use suggests that households are not using their filters or stoves on an exclusive basis, and may be both drinking untreated water at times and using other stoves ("stove-stacking"). These results provide additional evidence that surveys and direct observation may exaggerate compliance with household-based environmental interventions.

Abstract
OBJECTIVE We conducted a longitudinal study to assess the impact of a hand-washing intervention on growth and biomarkers of child health in Nepali slums. This is the first study to evaluate the impact of hand-washing on markers of subclinical, asymptomatic infections associated with childhood growth faltering. METHODS We recruited a total sample of infants in the target age-range (3-12 months) living in the eight largest Kathmandu slums, allocating them to intervention (n = 45) and control (n = 43) groups. In intervention areas, a small-scale community-based hand-washing program was implemented for six months; in control areas, mothers continued their normal practices. Time series linear regression was used to assess the impact of the intervention on levels of morbidity, mucosal damage, immune stimulation and growth. RESULTS As expected, children with higher levels of mucosal damage exhibited worse growth over the period of the intervention (P = 0.01, <0.001 and 0.03 for height-for-age, weight-for-age, and weight-for-height z-scores, respectively). We observed a 41% reduction in diarrheal morbidity (P = 0.023) for the intervention group relative to control. However, the hand-washing intervention did not lower levels of mucosal damage or immune stimulation, nor slow growth faltering. CONCLUSIONS Reducing exposure to pathogens is an important global health priority. This study confirms the importance of hand-washing campaigns for reducing childhood morbidity. Yet our data suggest that promoting hand-washing is necessary but not sufficient to address chronic, subclinical infections. From a human biology standpoint, tackling the root causes of childhood infections is needed to address growth faltering in the context of highly contaminated slum environments.

Abstract
Although promotion of safe hygiene is the single most cost-effective means of preventing infectious disease, investment in hygiene is low both in the health and in the water and sanitation sectors. Evidence shows the benefit of improved hygiene, especially for improved handwashing and safe stool disposal. A growing understanding of what drives hygiene behaviour and creative partnerships are providing fresh approaches to change behaviour. However, some important gaps in our knowledge exist. For example, almost no trials of the effectiveness of interventions to improve food hygiene in developing countries are available. We also need to figure out how best to make safe hygiene practices matters of daily routine that are sustained by social norms on a mass scale. Full and active involvement of the health sector in getting safe hygiene to all homes, schools, and institutions will bring major gains to public health.

Abstract
Background A previous study found that the prevalence of contamination with bacteria of faecal-origin on the hands of men differed across UK cities, with a general trend of increased contamination in northern cities. The aim of this study was to (1) confirm the north-south trend (2) identify causes for the trend. Methods Hand swabs from commuters (n = 308) at train stations in 4 cities were tested for the presence of faecal bacteria. Results The prevalence of hand contamination with faecal bacteria was again higher in cities in the north compared to the south (5% in London, 4% in Birmingham, 10% in Liverpool and 19% in Newcastle). Contamination risk decreased with age and better personal hygiene (self-reported). Soil contact and shaking hands increased contamination with faecal bacteria. However, in multivariable analysis, none of these factors fully explained the variation in contamination across cities. Conclusion The study confirmed the north-south differences in faecal contamination of hands without finding a clear cause for the trend. Faecal contamination of hands was associated with personal hygiene indicators suggesting that microbiological testing may contribute to evaluating hygiene promotion campaigns.

Abstract
This paper examines household and community-level influences on diarrhoeal prevalence in southern Malawi. A Bayesian multi-level modelling technique is used in the estimation of hierarchically built data from a survey of individuals nested within households nested within communities. Households have strong unobserved influence on diarrhoeal illness (sigma(2)(u) = 4.476; 95% CI: 2.081, 6.871). A joint Wald test of significance shows that an individual's age [chi(2)(4) = 55.921, p = 0.000] and school [chi(2)(2) = 18.203, p = 0.000] have strong influence on an individual's diarrhoeal prevalence. An individual's history of malarial-like illness also has a strong positive relationship with diarrhoeal prevalence [beta = 0.606, p = 0.000]. Household factors that influence diarrhoea include employment status of head of household [beta = -0.619, p < 0.021], maternal age [beta = -0.013, p < 0.003], and size of household [beta = -0.669, p = 0.000]. The positive relationship between diarrhoea and malaria-like episodes highlights common risk factors hence the need for common approaches to combat the diseases. Significant household effects underline the importance of household considerations in policy issues.

Abstract
Background Interventions to increase hand washing in schools have been advocated as a means to reduce the transmission of pandemic influenza and other infections. However, the feasibility and acceptability of effective school-based hygiene interventions is not clear. Methods A pilot study in four primary schools in East London was conducted to establish the current need for enhanced hand hygiene interventions, identify barriers to their implementation and to test their acceptability and feasibility. The pilot study included key informant interviews with teachers and school nurses, interviews, group discussions and essay questions with the children, and testing of organised classroom hand hygiene activities. Results In all schools, basic issues of personal hygiene were taught especially in the younger age groups. However, we identified many barriers to implementing intensive hygiene interventions, in particular time constraints and competing health issues. Teachers' motivation to teach hygiene and enforce hygienic behaviour was primarily educational rather than immediate infection control. Children of all age groups had good knowledge of hygiene practices and germ transmission. Conclusion The pilot study showed that intensive hand hygiene interventions are feasible and acceptable but only temporarily during a period of a particular health threat such as an influenza pandemic, and only if rinse-free hand sanitisers are used. However, in many settings there may be logistical issues in providing all schools with an adequate supply. In the absence of evidence on effectiveness, the scope for enhanced hygiene interventions in schools in high income countries aiming at infection control appears to be limited in the absence of a severe public health threat.

Abstract
OBJECTIVE To investigate the effectiveness of a hygiene promotion intervention based on germ awareness in increasing handwashing with soap on key occasions (after faecal contact and before eating) in rural Indian households. METHODS Cluster randomised trial of a hygiene promotion intervention in five intervention and five control villages. Handwashing was assessed through structured observation in a random sample of 30 households per village. Additionally, soap use was monitored in a sub-sample of 10 households per village using electronic motion detectors embedded in soap bars. RESULTS The intervention reached 40% of the target population. Germ awareness increased as well as reported handwashing (a possible indicator of perceived social norms). Observed handwashing with soap on key occasions was rare (6%), especially after faecal contact (2%). Observed handwashing with soap on key occasions did not change 4 weeks after the intervention in either the intervention arm (-1%, 95% CI -2%/+0.3%), or the control arm (+0.4%, 95% CI -1%/+2%). Data from motion detectors indicated a significant but small increase in overall soap use in the intervention arm. We cannot confidently identify the nature of this increase except to say that there was no change in a key measure of handwashing after defecation. CONCLUSION The intervention proved scalable and effective in raising hygiene awareness. There was some evidence of an impact on soap use but not on the primary outcome of handwashing at key times. However, the results do not exclude that changes in knowledge and social norms may lay the foundations for behaviour change in the longer term.

Abstract
Handwashing with soap (HWWS) may be one of the most cost-effective means of preventing infection in developing countries. However, HWWS is rare in these settings. We reviewed the results of formative research studies from 11 countries so as to understand the planned, motivated and habitual factors involved in HWWS. On average, only 17% of child caretakers HWWS after the toilet. Handwash 'habits' were generally not inculcated at an early age. Key 'motivations' for handwashing were disgust, nurture, comfort and affiliation. Fear of disease generally did not motivate handwashing, except transiently in the case of epidemics such as cholera. 'Plans' involving handwashing included to improve family health and to teach children good manners. Environmental barriers were few as soap was available in almost every household, as was water. Because much handwashing is habitual, self-report of the factors determining it is unreliable. Candidate strategies for promoting HWWS include creating social norms, highlighting disgust of dirty hands and teaching children HWWS as good manners. Dividing the factors that determine health-related behaviour into planned, motivated and habitual categories provides a simple, but comprehensive conceptual model. The habitual aspects of many health-relevant behaviours require further study.

Abstract
A liquid alcoholic extract of Papaver somniferum named Elixir Paregorico® is extensively used for diarrheal diseases in Brazil. Its increased popularity has brought concerns and fears over the safety of this herbal product. Given the lack of investigative clinical studies, in this regard, this study investigated whether Elixir Paregorico® administration causes any noticeable toxic effects in healthy volunteers. In all, 28 middle-aged healthy male ( n = 14) and female ( n = 14) were enrolled. After screening and a washout period, eligible subjects received four oral doses per day of Elixir Paregorico® (3 mL diluted in 30 mL of water) over a 10-day period. Altogether, all 28 participants completed the study. The results of hematological and biochemical tests performed pre and post-treatment were within the normal range. In both male and female volunteers, there were no statistical differences ( P > 0.05) in the results of clinical and laboratory tests performed at screening, on 5th and 10th day visits, and at final assessment. Although mild adverse events were related, which subsided spontaneously, no serious untoward reactions were reported following Elixir Paregorico® administration. To our knowledge, this is the first demonstration that Elixir Paregorico® administered four times a day for 10 days is safe and does not cause any noticeable toxic effect in healthy volunteers.

Abstract
The literature is growing on the subject of coping strategies. However, with the exception of some work on the promotion of oral rehydration therapy (ORT), very few studies have examined coping strategies as a response to the ongoing diarrhoeal disease burden. This is particularly relevant in the case of self-care, previously documented as the most readily implemented treatment in the developing world and an increasingly common health behaviour in rural Bangladesh. This study analysed the socioeconomic factors that influence the adoption of self-care and the role that varied asset availability plays in relation to households choosing, or being forced to implement, a coping strategy. Qualitative methods were used to collect data from three villages in Nilphamari District, North West Bangladesh, in 2004. The findings produced a detailed picture of asset availability and its influence on household use of self-care treatment practices. The strong role of aspects of social capital in building human capital was highlighted, as well as how these aspects of social capital can assist household welfare through self-care in times of diarrhoeal disease. In contrast, households exhibiting weakened social and human capital were more excluded from information on appropriate self-care treatments. Development agencies and health care policies might therefore strengthen levels of household resilience to diarrhoeal disease more cost-effectively by focusing on activities that facilitate self-care through support of social networks and education channels.

Abstract
Effective approaches for the prevention and reduction of obesity and obesity-related chronic diseases are urgently needed. Food store-centered programs represent one approach that may be both effective and sustainable. The authors developed a food store-based intervention in the Marshall Islands using qualitative and quantitative formative research methods, including a store usage survey (n = 184) and in-depth interviews with large-store managers (n = 13), small-store managers (n = 7), customers (n = 10), and community leaders (n = 4). This process was followed up by development and piloting of specific intervention components and workshops to finalize materials. The final intervention combined mass media (newspaper articles, video, radio announcements) and in-store components (shelf labels, cooking demonstrations, posters, recipe cards) and had high store-owner support and participation. High levels of exposure to the intervention were achieved during the 10-week period of implementation. This model for developing food store-based interventions is applicable to other settings.

Abstract
Formative research is used to inform intervention development, but the processes of transmitting results to intervention planners and incorporating information into intervention designs are not well documented. The authors describe how formative research results from the Trial of Activity for Adolescent Girls (TAAG) were transferred to planners to guide intervention development. Methods included providing oral and written reports, prioritizing recommendations, and cross-checking recommendations with intervention objectives and implementation strategies. Formative work influenced the intervention in many ways. For example, results indicated that middle schools offered only coeducational physical education and health education classes, so the TAAG intervention was designed to be appropriate for both sexes, and intervention strategies were developed to directly address girls' stated preferences (e.g., enjoyable activities, opportunity to socialize) and barriers (e.g., lack of skills, fear of injury) for physical activity. The challenges of using formative research for intervention development are discussed.

Abstract
BACKGROUND There is a need to enhance the quality and sustainability of environmental health programs in Mexico. What socio-cultural factors influenced the adoption or rejection of Clean Water in Homes programs in this population? We applied rapid appraisal procedures (RAP) to evaluate these community-based programs. METHOD Qualitative study conducted in communities along Mexico's northern border. We conducted informal dialogues, semi-structured interviews, field notes and observations. Home visits used a checklist to observe: sources of water, handwashing, as well as human waste and garbage disposal patterns. Data analysis was conducted using ATLAS.ti, which facilitated comparison and illustration of discrepancies, the elaboration of emerging issues and relationships between them. RESULTS Community members perceived that the Clean Water program was a top-down intervention. Water is perceived as a political issue and a matter of corruption. Inequity also limits solidarity activities involved in environmental sanitation. Migration to the United States of America (US) contributes to community fragmentation, which in turn dilutes communal efforts to improve water and sanitation infrastructure. While targeting women as program "recipients", the Clean Water program did not take gendered spheres of decision-making into account. Community members and authorities discussed the main results in "assemblies", particularly addressing the needs of excluded groups. CONCLUSION The oversight of not exploring community members' needs and priorities prior to program implementation resulted in interventions that did not address the structural (economic, infrastructure) and socio-cultural barriers faced by community members to undertake the health-promoting behaviour change, and provoked resentment.

Abstract
This review gives an overview of hand hygiene in healthcare and in the community, including some aspects which have attracted little attention, such as hand drying and cultural issues determining hand hygiene behaviour. Hand hygiene is the most effective measure for interrupting the transmission of microorganisms which cause infection both in the community and in the healthcare setting. Using hand hygiene as a sole measure to reduce infection is unlikely to be successful when other factors in infection control, such as environmental hygiene, crowding, staffing levels and education are inadequate. Hand hygiene must be part of an integrated approach to infection control. Compliance with hand hygiene recommendations is poor worldwide. While the techniques involved in hand hygiene are simple, the complex interdependence of factors which determine hand hygiene behaviour makes the study of hand hygiene complex. It is now recognised that improving compliance with hand hygiene recommendations depends on altering human behaviour. Input from behavioural and social sciences is essential when designing studies to investigate compliance. Interventions to increase compliance with hand hygiene practices must be appropriate for different cultural and social needs. New strategies to promote hand hygiene worldwide include the formation of public-private partnerships.

Abstract
OBJECTIVES To evaluate the public health impact of milk contamination in Bamako, Mali. METHODS A case-control study assessed the risk-factors for food-borne toxi-infections with diarrhoea and vomiting as main clinical picture. A total of 131 schoolchildren between 5 and 20 years of age were interviewed by trained interviewers in schools in Bamako. A structured questionnaire was used to record health problems, food and particularly milk consumption habits and socio-economic indicators. RESULTS Final multivariate logistic regression analysis identified regular consumption of boiled milk [odds ratio(OR) = 4.38; 95% CI = 1.15-16.71], age between 5 and 10 years (OR vs. age group 11-15 years = 3.28; 95% CI = 1.09-9.85) and the existence of dry latrines in the household (OR = 7.65; 95% CI = 1.92-30.55) as risk factors for diarrhoea and vomiting. Other milk products and the socio-economic level of the household were not significantly associated with the outcome. Many people were unaware of the potential risks of milk consumption. CONCLUSIONS Milk products may be a risk factor for food-borne toxi-infections. Attention has to be paid to products considered 'safe', such as boiled or pasteurized milk. The low awareness of potential risks of many people may increase the risk of milk consumption. To achieve a sustainable increase in local milk production in Africa, milk quantity and production and transformation quality should be improved simultaneously.

Abstract
Much infectious intestinal disease (IID) arises in the home environment. If programmes to prevent infection are to be effective it is essential to both identify the particular practices that risk disease transmission, and to understand the reasons for these practices. An in-depth, multidisciplinary study of carer and child hygiene in the domestic environment in the Wirral, UK, employed structured observation, surface swabbing for polio vaccine virus and enteric marker organisms, semi-structured interviews, projective interviews and focus group discussions. Observations revealed that child carers washed hands with soap after changing a dirty nappy on 42% of occasions, and that one in five toilet users did not wash hands with soap afterwards. Microbiological samples were taken from household surfaces at sites thought likely to be involved in the transfer of faecal material. 15% of bathroom samples showed contamination with polio vaccine virus. Nappy changing took place mainly in living rooms. Contact with living room surfaces and objects during nappy changing was frequent and evidence of faecal contamination was found in 12% of living room samples. Evidence of faecal contamination was also found in kitchens, again on surfaces thought likely to be involved in the transmission of faeces (taps and soap dispensers). Key factors motivating hygiene were the desire to give a good impression to others, protection of the child and aesthetics. In this setting, the particular risk practices to be addressed included washing hands with soap after stool and nappy contact and preventing the transfer of pathogenic organisms to the kitchen. The occasion of the birth of a child may be a privileged moment for the promotion of safer home hygiene practices. Using polio vaccine virus as an indicator of faecal contamination produces results that could be used in large-scale studies of household disease transmission. A better understanding of the household transmission of the agents of IID using multidisciplinary methods is needed if effective hygiene promotion programmes are to be designed.

Abstract
Infectious diseases are still the number one threat to public health in developing countries. Diarrhoeal diseases alone are responsible for the deaths of at least 2 million children yearly - hygiene is paramount to resolving this problem. The function of hygienic behaviour is to prevent the transmission of the agents of infection. The most effective way of stopping infection is to stop faecal material getting into the child's environment by safe disposal of faeces and washing hands with soap once faecal material has contaminated them in the home. A review of the literature on handwashing puts it top in a list of possible interventions to prevent diarrhoea. Handwashing with soap has been calculated to save a million lives. However, few people do wash their hands with soap at these critical times. Obtaining a massive increase in handwashing worldwide requires a sea-change in thinking. Initial results from a new programme led by the World Bank, with many partner organisations, suggest that health is low on people's list of motives, rather, hands are washed to remove dirt, to rinse food off after eating, to make hands look and smell good, and as an act of motherly caring. Professional consumer and market research agencies are being used to work with the soap industry to design professional communications programmes to reach whole populations in Ghana and India. Tools and techniques for marketing handwashing and for measuring the actual impact on behaviour will be applied in new public-private handwashing programmes, which are to start up soon in Nepal, China, Peru and Senegal.

Abstract
We set out to determine the impact of washing hands with soap on the risk of diarrhoeal diseases in the community with a systematic review with random effects meta-analysis. Our data sources were studies linking handwashing with diarrhoeal diseases. Seven intervention studies, six case-control, two cross-sectional, and two cohort studies were located from electronic databases, hand searching, and the authors' collections. The pooled relative risk of diarrhoeal disease associated with not washing hands from the intervention trials was 1.88 (95% CI 1.31-2.68), implying that handwashing could reduce diarrhoea risk by 47%. When all studies, when only those of high quality, and when only those studies specifically mentioning soap were pooled, risk reduction ranged from 42-44%. The risks of severe intestinal infections and of shigellosis were associated with reductions of 48% and 59%, respectively. In the absence of adequate mortality studies, we extrapolate the potential number of diarrhoea deaths that could be averted by handwashing at about a million (1.1 million, lower estimate 0.5 million, upper estimate 1.4 million). Results may be affected by the poor quality of many of the studies and may be inflated by publication bias. On current evidence, washing hands with soap can reduce the risk of diarrhoeal diseases by 42-47% and interventions to promote handwashing might save a million lives. More and better-designed trials are needed to measure the impact of washing hands on diarrhoea and acute respiratory infections in developing countries.

Abstract
Increasing resources are being allocated to environmental health monitoring, especially for developing methods and collecting data to construct environmental health indicators (EHIs). Yet, little research has focused on understanding how communities and service providers make decisions with regard to environmental health priorities and the role of indicators in this process. This paper presents insights regarding local decision-making that arose from a project to test the feasibility of using community-based EHIs to facilitate communication between the providers and the recipients of environmental services in four developing-country cities. The results of the study indicate that decision-making for environmental health services is complex and iterative rather than rational and linear. Contextual and process factors play an important role. These factors include the morale of service providers, the extent of collaboration between service agencies, the priorities of different community groups and relations between service providers and communities. Scientific information, in the form of EHIs, did not appear to be a key element of decision-making in the settings studied. As tools, EHIs are unlikely to become part of the decision-making process unless they are integrated with local agendas and backed by strong local representation.

Abstract
Improving domestic hygiene practices is potentially one of the most effective means of reducing the global burden of diarrhoeal diseases in children. However, encouraging behaviour change is a complex and uncertain business. If hygiene promotion is to succeed, it needs to identify and target only those few hygiene practices which are the major source of risk in any setting. Using biological reasoning, we hypothesize that any behaviours which prevent stools from getting into the domestic arena, the child's main habitat, are likely to have a greater impact on health than those practices which prevent pathogens in the environment from being ingested. Hence safe stool disposal, a primary barrier to transmission, may be more important than hand-washing before eating, which constitutes a secondary barrier, for example. We review the epidemiological evidence for the effect of primary and secondary barrier behaviours and suggest that it supports this conclusion. In the absence of local evidence to the contrary, hygiene promotion programmes should give priority to the safe disposal of faecal material and the adequate washing of hands after contact with adult and child stools.
