Mothers' personal and domestic hygiene and diarrhoea incidence in young children in rural Bangladesh.

This study examines the effect of maternal personal and domestic hygiene on the incidence of diarrhoea in children aged 6-23 months from rural areas around Teknaf, Bangladesh. The intervention area received augmented water supply through handpumps and health education while the control area received no project inputs. From July 1980 to June 1983, diarrhoea incidence was recorded weekly while mothers' personal and domestic hygiene was observed yearly. Annual incidence of diarrhoea in 314 children from the intervention area and 309 children from the control area was analysed in relation to maternal personal and domestic hygiene, controlling for education and occupation of household head and household size. Results show that, in both areas, use of handpump water for drinking and washing, removal of child's faeces from the yard, and maternal handwashing before handling food and after defaecation of self and child, observed together, decreased yearly diarrhoea incidence in children by more than 40% compared to children living in households where none or only one of these practices was observed.

The use of diarrhoeal management counselling cards for community health volunteer training in Indonesia: the HealthCom Project.

The Indonesian Ministry of Health relies on a network of over a million kader (community health volunteers) to bring primary health care to the village level. In West Java, the Department of Health's Control of Diarrhoeal Disease (CDD) Program recently carried out an extensive research and development effort to produce effective job aids for the kader in CDD and a training programme to teach their use. A set of counselling cards was produced to provide kader with a tool to diagnose and treat diarrhoea and teach the proper use of ORS. Researchers conducted a controlled evaluation in which they measured the cards' effectiveness through observations of kader performance and interviews with mothers they had counselled. In the intervention group, 15 kader underwent two days training in the use of the cards when diagnosing and advising treatment for cases of diarrhoea in their villages. The 16 control kader received comparable CDD training without the cards. Each group provided lists of local mothers they pledged to counsel during the coming weeks. Follow-up interviews were held with these mothers to test their level of knowledge on CDD and to observe their ability to mix ORS properly. Significant performance differences between the intervention kader and mothers, and the control kader and mothers, were demonstrated. The intervention kader were consistently more accurate in their diagnoses and recommendations for treatment with a mean of 83% accuracy vs 68% for the control kader. Mothers counselled by the intervention kader also prepared ORS significantly better than the mothers counselled by the control kader, with 97 vs 74% accuracy.

Field trial of oral cholera vaccines in Bangladesh: results from three-year follow-up.

The protective efficacy (PE) of B subunit killed whole-cell (BS-WC) and killed whole-cell-only (WC) oral cholera vaccines was assessed in a randomised double-blind field trial among children aged 2-15 years and women over 15 years in rural Bangladesh. Among the 62 285 subjects who received three doses of BS-WC, WC, or Escherichia coli K12 strain placebo, cumulative PE at 3 years of follow-up was 50% for BS-WC and 52% for WC. PE was similar against severe and non-severe cholera, but was significantly lower in children who were vaccinated at 2-5 years (26% for BS-WC; 23% for WC) than in older persons (63% for BS-WC; 68% for WC). Among persons vaccinated at 2-5 years, protection at 4-6 months of follow-up was similar to that for older persons, but rapidly waned thereafter and was not evident during the third year of follow-up. In contrast, persons vaccinated at older ages were protected even in the third year of follow-up (PE 40% for BS-WC; 62% for WC). PE was substantially higher against classical cholera (58% for BS-WC; 60% for WC) than against El Tor cholera (39% and 40%).

Health beliefs related to diarrhea in Haitian children: building transcultural nursing knowledge.

Regardless of where they live or under what circumstances, mothers throughout the world seem to have a compelling desire to provide the best possible health care for their children (Huston, 1979). Haitian mothers living in the Dominican Republic were no exception. The health beliefs and practices of these mothers related primarily to diarrhea among their children which demonstrated a concern and resourcefulness that is commendable. The results of this study clearly indicate the importance of transcultural nurses conducting culturally relevant research as a basis to develop sound health programs in developing countries. Diarrhea was identified as the single most important threat to a child's health in these communities. That mothers did not know about the correct ingredients and/or proportions for oral rehydration solutions (Western views) was of interest. Although the Dominican government makes some commercial packets of ORS, most of the women interviewed did not have ready access to this product. This finding reflected the need for transcultural nurses to offer to teach mothers how to make ORS using the sugar, salt, and water they had available. Since the mothers' perception that diarrhea was a dangerous threat to their children's health, was verified by childhood mortality statistics in the bateys, it would seem that ORS could make a significant impact on the health status of the children. Breastfeeding also was a major health belief factor associated with the treatment of diarrhea. Even though the majority of mothers believed breast feeding should be continued if a child had diarrhea, a number believed it should be discontinued. Nurses working with CHWs will need to emphasize the importance of breastfeeding and help them to develop creative ways of communicating this information to the mothers. The second most dangerous threat to the child identified by the mothers was respiratory ailments. This suggests a new area of concentration for future research and training of CHWs. A host of new questions related to respiratory problems such as health beliefs, causative factors, course of disease, traditional treatments, mortality rate, etc. need to be investigated. When transcultural nurses plan health care programs for women and children in other cultures, it is important to recognize the concerns mothers have for their children, and their intense desire to nature and care for them. In this study, mothers willingly participated and demonstrated active interest in learning to use methods to improve the health and well being of their children. It is well documented (Lieban, 1977) that established health beliefs are not automatically discarded when new knowledge is made available, but that exploration and incorporation of new information when presented in a culturally relevant framework does occur. An understanding of local beliefs surrounding health is fundamental to the development of appropriate transcultural nursing interventions.

Hypernatraemia surveillance during a national diarrhoeal diseases control project in Egypt.

The nationwide introduction of oral rehydration therapy to Egypt has led to improvement in diarrhoea case management and a fall in infant and child mortality. With the wider use of oral rehydration solution (ORS) prepared from packets, the incidence of hypernatraemia (serum sodium greater than 150 mmol/l) in inpatients with dehydration seen at Abu El-Reeche Hospital, Cairo, increased between 1980 and 1984. Systematic surveillance of hypernatraemia in the outpatient rehydration unit began in late 1984, and we report trends in hypernatraemia and analyses of key variables affecting its incidence in dehydrated children. In 1980, 17 of 100 children sampled had hypernatraemia and 2 had severe hypernatraemia (ie, serum sodium greater than 165 mmol/l). The frequency in inpatients peaked at 49% of 222 children in 1984 (19% with severe hypernatraemia). Between 1986 and 1989, at least 1000 dehydrated outpatients were surveyed each year; by 1989 the incidence of hypernatraemia had fallen to around 10% (2% severe hypernatraemia). The rise and decline coincided with increasing use of ORS and then increasing ability of mothers to mix the solution correctly. Hypernatraemia was positively related to the quantity of ORS taken, severity of dehydration, nutritional status, and the cooler season, and negatively related to age and duration of diarrhoea. Explanations for our findings include improved use of ORS and better case-management. Good practice promoted through the mass media has facilitated these changes; if the standard of ORS use is not maintained, there may be a case for reducing the sodium content of ORS.

Formulae of sugar-salt solutions recommended for treatment of diarrhoeal dehydration at home in African countries.

During a conference on diarrhoeal diseases in Tanzania in 1984, 19 participants representing 16 countries in Africa gave the formulae for oral rehydration solutions therapy (ORS) which they recommended or instructed for home use in their own countries. There were gross variations in recommended quantities of sugar, salt and water. Theoretical calculations indicated that the glucose concentration ranged from 29 to 174 mmol/l (recommended 30-112 mmol/l) and that of sodium from 9 to 116 mmol/l (recommended 30-80 mmol/l). It is very important that countries should ensure that the recommendations for making up oral rehydration solutions be standardized, otherwise dangerous or ineffectual concentrations of salt and sugar solutions may be used for rehydrating children.

Perceived causes and traditional treatment of diarrhoea by mothers in Eastern Sudan.

Mothers of Eastern Sudan seek or practice traditional treatment for diarrhoeal disease in their children based on their perception of causation. Fifty-six mother groups from 39 villages and 17 urban centres were surveyed in this study. The collected data were grouped by definition of diarrhoea, its perceived causes and practiced treatment thought to be appropriate. Differences were shown between the urban and rural groups. A longer list of perceived causes was obtained from rural mothers. Fumigation and use of rice water and custard were the preferred managements of urban mothers, while cautery, use of mihaya and goat's milk prevailed in rural areas. The importance of having the definition of diarrhoea cited in future studies is discussed and recommended.

Osmolalities of bottle- and breast-milk fed to poor urban Brazilian infants.

Feeding practices related to osmotic strength of bottle-milk and breast-milk were studied in 133 families with infants less than 1 year of age in a poor urban settlement in Brasilia, Brazil. Osmolality [mean (SEM)] of breast-milk [318.8 (4.46) mOsm/kg water] was significantly less than that of bottle-milk [568.7 (29.9) mOsm/kg water]. The wide range of osmotic strength (253.7-1,380.0 mOsm/kg water) found in bottle-milk was partly due to the predominant use (82%) of powdered cow's milk among non-breastfeeders and its improper reconstitution. Diarrhoea and feeding management are also discussed.

Turning off the diarrhea: the role of food and ORS.

Ninety-three boys aged 5 years or less who had diarrhea due to Vibrio cholerae were randomly assigned to treatment with glucose oral rehydration salt (ORS) or rice-based ORS. For the first 24 h, ORS only was given to all the patients. During the next 24 h, ORS and normal food were given. The efficacy of the two types of ORS was compared in terms of ORS intake, stool output, change in hematocrit reading, serum specific gravity, and increase in body weight. At the end of the first 24 h of treatment, a 50% reduction in ORS intake and stool output was observed in the 47 patients randomly assigned to receive rice ORS as compared with the 46 patients who received glucose ORS. During the second 24 h of treatment, a significant reduction in the stool output was noticed in the glucose ORS group, making the efficacy of glucose ORS equal to that of rice ORS. The study suggests that normal food can impart some of the superiority of "super" ORS to standard glucose ORS with regard to reduction of stool volume.

Value of a chicken-based formula for refeeding of children with protracted diarrhea and malnutrition in a developing country.

Two hospital-made, lactose-free, hypoosmolar formulas were compared for therapy for 61 children aged 10-28 months who had severe malnutrition and protracted diarrhea. The formulas were isocaloric and contained dextrin-maltose, carrots, sunflower oil, minerals, and vitamins. One had chicken meat as the protein source and the other had hydrolyzed lactalbumin (LAD). Initially the formulas were given as a continuous enteral feeding by nasogastric tube and pump. Six patients died from metabolic and infectious complications: four failed to equilibrate and changed diet. The remaining 51 were divided into two groups; group A, chicken formula (n = 26), and group B, LAD formula (n = 25). The mean duration of diarrhea was similar in both groups; number of days with liquid stools = 6.0 +/- 4.1 in group A, 5.5 +/- 2.8 in group B; number of days with greater than 4 stools/day = 3.5 +/- 3.4 in group A, 4.1 +/- 2.1 in group B. The time until beginning nutritional recovery was 13.2 +/- 12.0 days in group A and 13.3 +/- 7.8 days in group B. Intercurrent infections were significantly more frequent in patients receiving chicken formula (12 of 30 patients) than in those receiving LAD formula (4 of 27 patients) (p less than 0.05). We conclude that chicken formula is an efficient substitute to expensive semielemental formulas for continuous enteral feeding of protracted diarrhea in severely malnourished children.

A comparative study of specific gene probes and standard bioassays to identify diarrhoeagenic Escherichia coli in paediatric patients with diarrhoea in Bangladesh.

We compared the usefulness of gene probes with standard bioassays to identify diarrhoeagenic Escherichia coli amongst isolates from Bangladeshi children under 1 year of age with diarrhoea. E. coli isolates were analysed with specific gene probes for localised adhesiveness (LA), diffuse adhesiveness (DA), heat-labile toxin (LT), heat-stable toxin (ST), Shiga-like toxins (SLT I and SLT II), and enteroinvasiveness, and in bioassays for production of enterotoxins and cytotoxins, and for cell adherence. With 1136 isolates from 387 patients, there was general agreement between the two assay methods. When there was disparity, gene-probe-positive isolates gave negative results in the corresponding bioassay. In the HeLa cell adherence assay, 94% of the LA probe-positive isolates and 91.6% of the DA probe-positive isolates gave positive bioassay results for LA and DA respectively. Thirty-six of 39 LT probe-positive isolates and 73 of 86 ST probe-positive isolates gave positive results in the bioassays. Of 28 isolates that gave negative results in the suckling mouse assay but were initially positive with the probe for ST, 15 were later found to hybridize with the cloning vector for the ST probe. Addition of denatured vector DNA at a concentration of 10 micrograms/ml in the hybridisation solution eliminated these false positive results. None of the other probe-positive isolates hybridised with any of the cloning vectors used. The DNA hybridisation assay appeared to be a convenient alternative to bioassays for screening large numbers of isolates in epidemiological investigation.

Health education through interactive radio: a child-to-child project in Bolivia.

In developing countries it is common for older children to assume much of the responsibility for care of their younger siblings. Based on this observation, the "child-to-child" approach to health education targets these older children as a means of improving child health. As the initial phase in the development of a radio health curriculum in Bolivia, a module on diarrheal disease was developed and field-tested among fourth- and fifth-grade students in Cochabamba. The module consists of 10 interactive radio lessons in which the students respond orally to drill and practice, sing songs, or write key concepts in their notebooks. Following the 25-minute radio broadcast, the teacher conducts a 20-minute session that focuses on application and practice of the new behaviors. The module includes lessons on personal hygiene, water and oral rehydration, home sanitation, and nutrition. The field evaluation revealed the need for modifications in the teachers' role and greater attention to teacher training. Students responded enthusiastically and achieved significant knowledge gains as a result of the program. Plans are underway to expand the radio health program.

The role of breast milk in protecting urban Peruvian children against cryptosporidiosis.

To test the hypothesis that breast milk of nursing mothers may afford children protection against cryptosporidiosis, a prospective cohort study was carried out in the young peoples' community of San Juan de Miraflores near Lima, Peru. Mothers and newborn children were sorted into cohort groups based on the mothers' breast milk antibody response to Cryptosporidium sporozoites using an antibody-capture enzyme-linked immunosorbent assay to detect parasite-specific immunoglobulin A. Children were monitored for Cryptosporidium infection using an indirect immunofluorescence assay. Of 211 mothers enrolled in the study, 39 (18.5%) had high breast milk antibody titers, 107 (50.7%) had medium titers, and 65 (30.8%) had low titers. Sixty-one episodes of Cryptosporidium infection were detected in 50 children of these mothers. Eleven (22%) had mothers in the high antibody titer group, 20 (40%) had mothers in the medium titer group, and 19 (38%) had mothers in the low titer group. The prevalence of infection within children of each group was 0.17, 0.19 and 0.38 respectively. There was no significant difference in the prevalence or duration of infection among children of the different groups. The data does not support the notion that there is protection from Cryptosporidium infection afforded children whose mothers have demonstrable breast milk antibodies against the parasite.

Oral rehydration therapy: a community trial comparing the acceptability of homemade sucrose and cereal-based solutions.

Sugar-based oral rehydration therapy (ORT) for diarrhoea is promoted in many countries of the world. One programme in Bangladesh has instructed more than 13 million mothers in the preparation of a sugar-salt solution in the home; despite very high rates of correct mixing and knowledge, subsequent application was found in only some 20% of all diarrhoea episodes. Since rice is far more available in rural homes (95%) than any type of sugar (30%) and rice gruel is a widely accepted food during illness, a field trial was conducted in three areas (total population, 68,345) to compare the acceptability and use of rice-based ORT with that of sugar-based ORT. Although the mothers unanimously agreed that the rice-based solutions "stopped" the diarrhoea more quickly, they used the sugar-based solutions twice as often (in 40% of severe watery episodes) as the rice-based solutions (in 18%), because the rice-ORT was much more time-consuming and difficult to prepare. The observed reduced utilization of home-made rice-ORT makes it a poor substitute for sugar-ORT at the community level in rural Bangladesh.

Bacterial indicators of risk of diarrhoeal disease from drinking-water in the Philippines.

Inadequate measures of water quality have been used in many studies of the health effects associated with water supplies in developing countries. The present 1-year epidemiological-microbiological study evaluated four bacterial indicators of tropical drinking-water quality (faecal coliforms, Escherichia coli, enterococci and faecal streptococci) and their relationship to the prevalence of diarrhoeal disease in a population of 690 under-2-year-olds in Cebu, Philippines. E. coli and enterococci were better predictors than faecal coliforms of the risk of waterborne diarrhoeal disease. Methods to enumerate E. coli and enterococci were less subject to interference from the thermotolerant, non-faecal organisms that are indigenous to tropical waters. Little difference was observed between the illness rates of children drinking good quality water (less than 1 E. coli per 100 ml) and those drinking moderately contaminated water (2-100 E. coli per 100 ml). Children drinking water with greater than 1000 E. coli per 100 ml had significantly higher rates of diarrhoeal disease than those drinking less contaminated water. This threshold effect suggests that in developing countries where the quality of drinking-water is good or moderate other transmission routes of diarrhoeal disease may be more important; however, grossly contaminated water is a major source of exposure to faecal contamination and diarrhoeal pathogens.

Role of breast-feeding in the prevention and treatment of diarrhoea.

Recent studies have again shown the beneficial effects of breast-feeding in preventing morbidity and mortality from diarrhoea in infants. A case-control study in Brazil has shown that young infants who are not breast-fed have a 25-time greater risk of dying of diarrhoea than those who are exclusively breast-fed. A longitudinal study in the urban slums of Lima, Peru found that exclusively breast-fed infants have a reduced risk of diarrhoeal morbidity when compared with infants receiving only water in addition to breast-milk. Both these studies, along with numerous others in developing countries, point to the need to extend the duration of exclusive breast-feeding to at least 4-6 months. A review of concerned studies throughout the world shows that even in malnourished women, breast-milk output is sufficient to maintain growth of infants up to this age. The addition of early food supplements to infants fed under prevailing environmental conditions in developing countries leads to their increased diarrhoeal attacks and associated reduced food intake. This results in worsened nutritional status of the affected infants. Breast-feeding helps maintain hydration status during diarrhoeal episodes. Studies in Peru, India, and Nigeria have shown that breast-feeding can be continued during diarrhoea when the infants often refuse other foods, specially non-human milk. Thus, breast-feeding is important in providing necessary calories and protein during a time when a loss of appetite for other foods is common. Diarrhoeal disease control programmes need to modify service delivery to ensure that breast-feeding mothers are not separated from their infants while being treated with oral rehydration therapy (ORT) as inpatients or outpatients. Oral rehydration solution (ORS) should be given to infants with cup and spoon rather than bottles, in order not to interfere with suckling. When in a health system bottles are used for treatment, an implicit credibility is given to their role in modern treatment. Programmes also need to include breast-feeding promotion as a part of their activities. This should comprise hospital practices supporting and ensuring breast-feeding immediately after delivery of the infants and subsequently while they are treated in the hospital: immediate breast-feeding after delivery; Mothers and infants rooming together; On demand breast-feeding; No bottle feedings of water or infant formula; No pre-lacteal feeds. In addition, health professionals need to understand the skills for the management of breast-feeding, so that mothers are given appropriate advice on how to breast-feed and counteract breast-feeding problems.
