The recognition of and care seeking behaviour for childhood illness in developing countries: a systematic review. PLoS One 2014; 9:e93427.

Abstract
BACKGROUND Pneumonia, diarrhoea, and malaria are among the leading causes of death in children. These deaths are largely preventable if appropriate care is sought early. This review aimed to determine the percentage of caregivers in low- and middle-income countries (LMICs) with a child less than 5 years who were able to recognise illness in their child and subsequently sought care from different types of healthcare providers. METHODS AND FINDINGS We conducted a systematic literature review of studies that reported recognition of, and/or care seeking for episodes of diarrhoea, pneumonia or malaria in LMICs. The review is registered with PROSPERO (registration number: CRD42011001654). Ninety-one studies met the inclusion criteria. Eighteen studies reported data on caregiver recognition of disease and seventy-seven studies on care seeking. The median sensitivity of recognition of diarrhoea, malaria and pneumonia was low (36.0%, 37.4%, and 45.8%, respectively). A median of 73.0% of caregivers sought care outside the home. Care seeking from community health workers (median: 5.4% for diarrhoea, 4.2% for pneumonia, and 1.3% for malaria) and the use of oral rehydration therapy (median: 34%) was low. CONCLUSIONS Given the importance of this topic to child survival programmes there are few published studies. Recognition of diarrhoea, malaria and pneumonia by caregivers is generally poor and represents a key factor to address in attempts to improve health care utilisation. In addition, considering that oral rehydration therapy has been widely recommended for over forty years, its use remains disappointingly low. Similarly, the reported levels of care seeking from community health workers in the included studies are low even though global action plans to address these illnesses promote community case management. Giving greater priority to research on care seeking could provide crucial evidence to inform child mortality programmes.

Performance criteria for verbal autopsy-based systems to estimate national causes of death: development and application to the Indian Million Death Study. BMC Med 2014; 12:21. [PMID: 24495287 PMCID: PMC3912490 DOI: 10.1186/1741-7015-12-21] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2013] [Accepted: 11/26/2013] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Verbal autopsy (VA) has been proposed to determine the cause of death (COD) distributions in settings where most deaths occur without medical attention or certification. We develop performance criteria for VA-based COD systems and apply these to the Registrar General of India's ongoing, nationally-representative Indian Million Death Study (MDS). METHODS Performance criteria include a low ill-defined proportion of deaths before old age; reproducibility, including consistency of COD distributions with independent resampling; differences in COD distribution of hospital, home, urban or rural deaths; age-, sex- and time-specific plausibility of specific diseases; stability and repeatability of dual physician coding; and the ability of the mortality classification system to capture a wide range of conditions. RESULTS The introduction of the MDS in India reduced the proportion of ill-defined deaths before age 70 years from 13% to 4%. The cause-specific mortality fractions (CSMFs) at ages 5 to 69 years for independently resampled deaths and the MDS were very similar across 19 disease categories. By contrast, CSMFs at these ages differed between hospital and home deaths and between urban and rural deaths. Thus, reliance mostly on urban or hospital data can distort national estimates of CODs. Age-, sex- and time-specific patterns for various diseases were plausible. Initial physician agreement on COD occurred about two-thirds of the time. The MDS COD classification system was able to capture more eligible records than alternative classification systems. By these metrics, the Indian MDS performs well for deaths prior to age 70 years. The key implication for low- and middle-income countries where medical certification of death remains uncommon is to implement COD surveys that randomly sample all deaths, use simple but high-quality field work with built-in resampling, and use electronic rather than paper systems to expedite field work and coding. CONCLUSIONS Simple criteria can evaluate the performance of VA-based COD systems. Despite the misclassification of VA, the MDS demonstrates that national surveys of CODs using VA are an order of magnitude better than the limited COD data previously available.

Abstract
Many community-based studies of acute child illness rely on cases reported by caregivers. In prior investigations, researchers noted a reporting bias when longer illness recall periods were used. The use of recall periods longer than 2-3 days has been discouraged to minimize this reporting bias. In the present study, we sought to determine the optimal recall period for illness measurement when accounting for both bias and variance. Using data from 12,191 children less than 24 months of age collected in 2008-2009 from Himachal Pradesh in India, Madhya Pradesh in India, Indonesia, Peru, and Senegal, we calculated bias, variance, and mean squared error for estimates of the prevalence ratio between groups defined by anemia, stunting, and underweight status to identify optimal recall periods for caregiver-reported diarrhea, cough, and fever. There was little bias in the prevalence ratio when a 7-day recall period was used (<10% in 35 of 45 scenarios), and the mean squared error was usually minimized with recall periods of 6 or more days. Shortening the recall period from 7 days to 2 days required sample-size increases of 52%-92% for diarrhea, 47%-61% for cough, and 102%-206% for fever. In contrast to the current practice of using 2-day recall periods, this work suggests that studies should measure caregiver-reported illness with a 7-day recall period.

Abstract
The health benefits of exclusive breastfeeding are well-known, but the relative detrimental impacts of other foods on infant health are unknown. Because infants in developing countries are fed a wide range of food, quantifying the burden of these diverse feeding practices on infant health is essential for public health policy. We used data from the Demographic Health Survey from 20 developing countries over multiple years to examine the independent association of six different types of food (exclusive breastfeeding, non-exclusive breastfeeding, infant formula, milk liquids, non-milk liquids, and solid foods) with five measures of infant health (length, weight, diarrhea, fever, and cough). We estimated associations with regression analysis, controlling for confounding factors with infant, mother, and household factors and community-year fixed effects. We used these estimates in a simulation model to quantify the burden of different combinations of food on infant health. We show that for an infant younger than 6 months old, following current guidelines and exclusively breastfeeding instead of giving the infant solid foods may increase length by 0.75 cm and weight by 0.25 kg and decrease diarrhea, fever, and cough prevalence by 8, 12, and 11%, respectively. We found that the burden on infant health of some feeding practices is less than others. Although all other feeding practices are associated with worse health outcomes than exclusive breastfeeding, breastfeeding supplemented with liquids has a lower burden on infant health than solid foods and infant formula has a lower burden than milk or non-milk liquids as measured by four of five health metrics. Providing specific quantified burden estimates of these practices can help inform public health policy related to infant feeding practices.

Abstract
Background The longitudinal birth cohort study is the preferred design for studies of childhood health, particularly atopic disease. Still, prospective data collection depends on recollection of the medical history since the previous visit representing a potential recall-bias. We aimed to ascertain the quality of information on atopic disease and other health symptoms reported by parental interview in a closely monitored birth cohort study. Possible bias from symptom severity and socioeconomics were sought. Methods Copenhagen study on Asthma in Childhood (COPSAC) is a clinical birth cohort study of 411 children born of asthmatic mothers from 1999 to 2001. Child health is monitored at six-monthly visits with particular emphasis on atopic symptoms and infections. Data from the first three study years on 260 children was compared with records from their family practitioner as an external reference. Results A total of 6134 medical events were reported at the COPSAC interviews. Additional 586 medical events were recorded by family practitioners but not reported at the interview. There were no missed events related to asthma, eczema or allergy. Respiratory, infectious and skin related symptoms showed completeness above 90%, other diseases showed lower completeness around 77%. There was no meaningful influence from concurrent asthma or socioeconomics. Conclusions The COPSAC study exhibited full sensitivity to the main study objectives, atopic disease, and high sensitivity to respiratory, infectious and skin related illness. Our findings support the validity of parental interviews in longitudinal cohort studies investigating atopic disease and illness in childhood.

Abstract
Firstly, this review was performed to assess the effect of breastfeeding on infections during infancy in industrialized countries. Secondly, the effect of duration and exclusiveness of breastfeeding were explored. Studies were identified using Medline, Cochrane Library, Science Citation Index and by a manual search from bibliographies of articles from August 1986 to January 2008. Follow-up, case-control and randomized controlled trial (RCT) studies performed in an industrialized country, published in English, with breastfeeding as a determinant, with overall infections, gastrointestinal or respiratory tract infections as a major outcome, and at least 40 participants in the study were included. Using Bauchner's criteria published in a review in 1986, two reviewers and a peer reviewer assessed the internal validity of those studies. Twenty-one studies that met the inclusion and internal validity criteria were included. These included 16 follow-up and four case-control studies and one RCT. Four out of five studies observed decreased effects on overall infections in breastfed infants. With regard to gastrointestinal infections, six out of eight studies suggested that breastfeeding had a protective effect. Thirteen out of 16 studies concluded that breastfeeding protects infants against respiratory tract infections. Five studies combined duration and exclusiveness of breastfeeding. All studies observed a protective dose/duration-response effect on gastrointestinal or respiratory tract infections. These studies strongly suggest that breastfeeding protects infants against overall infections, gastrointestinal and respiratory tract infections in industrialized countries. The optimal duration of exclusive breastfeeding for protection against infectious diseases needs to be studied in more detail.

Abstract
Water and sanitation services are fundamental to the prevention of pediatric diarrhea. To enhance both access to water and investment, some argue for the privatization of municipal water networks. Water networks in multiple Bolivian cities were privatized in the 1990s, but contracts ended following popular protests citing poor access. A population-based retrospective cohort study was conducted in two Bolivian cities. Data were collected on family water utilization and sanitation practices and on the prevalence of diarrhea among 596 children. Drinking from an outdoor water source (OR, 2.08; 95%CI, 1.25-3.44) and shorter in-home water boiling times (OR, 1.99; 95%CI, 1.19-3.34) were associated with prevalence of diarrhea. Increased prevalence was also observed for children from families using private versus public water services, using off-network water from cistern trucks, or not treating their water in-home. Results suggest that water source, water provider, and in-home water treatment are important predictors of pediatric diarrhea.

Abstract
Vietnam's sustained investment in primary healthcare since the onset of socialism has lowered infant and childhood mortality rates and improved life expectancy, exceeding progress achieved in other poor countries with comparable levels of income per capita. The recent introduction of user fees for primary healthcare services has generated concern that economic policies may have adversely affected health-seeking behavior and health outcomes of the poor, particularly among impoverished families who are members of socially marginalized minority groups. This paper examines this debate by analyzing parental recall of illness and care-seeking for sick children under the age of 5 years recorded by the 2001-2002 Vietnam National Health Survey. We estimate statistical models of the determinants of parental recall of incidence and response to illness among their children. Ethnic minority parents less frequently reported their children to have been sick than Kinh and Chinese parents. When they recognize an illness episode, minority parents are less likely to seek care -- whether professional consultation or self-prescribed care -- than non-minority parents. Ethnic differentials are evident in all geographic and income levels, although adverse effects of minority status are most pronounced among poor households in remote areas. Regression estimates of the effects of ethnicity and maternal education on health decisions are pronounced even when poverty effects are controlled, suggesting that social equity may have been under-emphasized in Vietnam's early health policy deliberations. Policies extending free healthcare to poor communes affect parental decisions to seek professional care or self-prescribed care among better-off parents without affecting parental decision making among the poor. Early health initiatives for the poor may therefore have failed to offset equity problems confronting impoverished ethnic minority families.

Abstract
OBJECTIVE To assess the effectiveness of a behaviour change approach, with or without financial support, in improving vitamin A (VA) intake and serum retinol concentration through mango and liver consumption by children. DESIGN A parallel design (no control area) was used to assess changes in VA intake and serum retinol over a 15-week period. SETTING AND SUBJECTS A pilot study was implemented in the Department of Kokologho, a rural area in central west Burkina Faso. One hundred and fifty children aged 2-3 years were randomly selected and assigned to two treatment groups: PA$$ (promotional activities and financial support) and PA (promotional activities). RESULTS The intervention significantly increased (P < 0.001) total VA intake by 56% in PA$$ and by 50% in PA. VA intake from liver increased significantly (P < 0.001) from 12.7 +/- 23.5 to 155.3 +/- 56.3 microg retinol activity equivalents (RAE) in PA$$ and from 21.6 +/- 29.7 to 135.3 +/- 44.9 microg RAE in PA. Changes in VA intake from liver were significantly higher (P = 0.004) in PA$$ compared with PA. Mean serum retinol concentration increased significantly by 26% (P < 0.001) in PA$$ and 30% (P < 0.001) in PA. Changes in serum retinol concentration (0.13 micromol l(-1) in PA$$ vs. 0.17 micromol l(-1) and in PA) did not differ significantly (P = 0.455) between groups over the intervention. CONCLUSION Promotional activities on mango and liver intake effectively increased VA intake and serum retinol concentrations. Although an additional beneficial effect of financial support on liver intake was observed, this did not translate into a further increase in serum retinol concentration.

Abstract
AbstractObjective:To demonstrate the effectiveness of the commercial introduction of red palm oil (RPO) as a source of vitamin A (VA) for mothers and children in a non-consuming area, as a dietary diversification strategy.Design:A pre–post intervention design (no control area) was used to assess changes in VA intake and status over a 24-month pilot project.Setting and subjects:The pilot project involved RPO promotion in 10 villages and an urban area in east-central Burkina Faso, targeting approximately 10?000 women and children aged < 5 years. A random sample of 210 mother–child (12–36-months-old) pairs was selected in seven out of the 11 pilot sites for the evaluation.Results:After 24 months, RPO was reportedly consumed by nearly 45% of mothers and children in the previous week. VA intake increased from 235 ± 23 μg retinol activity equivalents (RAE) to 655 ± 144 μg RAE in mothers (41 to 120% of safe intake level), and from 164 ± 14 μg RAE to 514 ± 77 μg RAE in children (36 to 97%). Rates of serum retinol < 0.70 μmoll−1decreased from 61.8 ± 8.0% to 28.2 ± 11.0% in mothers, and from 84.5 ± 6.4% to 66.9 ± 11.2% in children. Those with a lower initial concentration of serum retinol showed a higher serum retinol response adjusted for VA intake.Conclusions:Commercial distribution of RPO was effective in reducing VA deficiency in the pilot sites. While it is promising as part of a national strategy, additional public health and food-based measures are needed to control VA malnutrition, which remained high in the RPO project area

Abstract
BACKGROUND Over 75% of the annual estimated 9.5 million deaths in India occur in the home, and the large majority of these do not have a certified cause. India and other developing countries urgently need reliable quantification of the causes of death. They also need better epidemiological evidence about the relevance of physical (such as blood pressure and obesity), behavioral (such as smoking, alcohol, HIV-1 risk taking, and immunization history), and biological (such as blood lipids and gene polymorphisms) measurements to the development of disease in individuals or disease rates in populations. We report here on the rationale, design, and implementation of the world's largest prospective study of the causes and correlates of mortality. METHODS AND FINDINGS We will monitor nearly 14 million people in 2.4 million nationally representative Indian households (6.3 million people in 1.1 million households in the 1998-2003 sample frame and 7.6 million people in 1.3 million households in the 2004-2014 sample frame) for vital status and, if dead, the causes of death through a well-validated verbal autopsy (VA) instrument. About 300,000 deaths from 1998-2003 and some 700,000 deaths from 2004-2014 are expected; of these about 850,000 will be coded by two physicians to provide causes of death by gender, age, socioeconomic status, and geographical region. Pilot studies will evaluate the addition of physical and biological measurements, specifically dried blood spots. Preliminary results from over 35,000 deaths suggest that VA can ascertain the leading causes of death, reduce the misclassification of causes, and derive the probable underlying cause of death when it has not been reported. VA yields broad classification of the underlying causes in about 90% of deaths before age 70. In old age, however, the proportion of classifiable deaths is lower. By tracking underlying demographic denominators, the study permits quantification of absolute mortality rates. Household case-control, proportional mortality, and nested case-control methods permit quantification of risk factors. CONCLUSIONS This study will reliably document not only the underlying cause of child and adult deaths but also key risk factors (behavioral, physical, environmental, and eventually, genetic). It offers a globally replicable model for reliably estimating cause-specific mortality using VA and strengthens India's flagship mortality monitoring system. Despite the misclassification that is still expected, the new cause-of-death data will be substantially better than that available previously.

Abstract
BACKGROUND Insufficient attention has been paid to the health problems of school-age children in sub-Saharan Africa. A questionnaire administered to schoolchildren about their ill-health has been developed to identify schools in which urinary schistosomiasis occurs. The data collected during the interviews can also be used to assess other common health problems. OBJECTIVES To analyse data collected during health questionnaires in schools to assess how schoolchildren perceive their own health, and to compare the findings between three countries in sub-Saharan Africa. METHODS Questionnaires asking about recent health problems were administered by teachers to schoolchildren in 120 primary schools in Mozambique, 52 primary schools in Tanzania and 298 primary schools in Ghana. A total of 67 002 children aged 8-15 years took part. RESULTS Of the 10 health problems asked about in all questionnaires, the average number reported by each child was 3.9 in Ghana, 3.4 in Mozambique and 3.1 in Tanzania. The distributions of the prevalence of each condition among schools were similar and the prevalence of all conditions showed a similar ranking. For most conditions a greater percentage of girls than boys reported each health problem. CONCLUSIONS Schoolchildren in Ghana, Mozambique and Tanzania do not perceive themselves to be healthy. The pattern of reported health problems was similar in each country. School health questionnaires are worthy of further study and validation.

Abstract
OBJECTIVE The aim of the study was to estimate the prevalence of diarrhoea in children less than two years old and study the relationship between diarrhoeal episodes and action taken for these episodes by their mothers. DESIGN The prevalence of diarrhoeal episodes among children and its associations with sociodemographic information and anthropometric measurements of the subjects was examined. Predictive factors for morbidity-associated diarrhoeal disease and actions taken for this were explored. SETTING Primary health care centres (PHCCs) in Riyadh, Kingdom of Saudi Arabia. SUBJECTS Children less than two years of age. RESULTS Nearly a quarter of the children contracted diarrhoea during the two weeks preceding the data collection point, giving about six episodes of diarrhoea per child per year. Diarrhoea was more common in children over 6 months of age, in children who had no vaccination or follow-up cards, and in those who were taken care of by friends and neighbours if their mothers were working outside the home. The mothers of the affected children were young, married before 25 years of age with 2-6 years of formal schooling. During diarrhoeal episodes, about 25% of mothers stopped or decreased breast-feeding, 11.3% reduced the volume of fluids given to their children, and 22.7% of children were fed less solid/semi-solid foods. Mothers used oral rehydration salt in more than 40% of diarrhoeal episodes and unprescribed antibiotics were used in 17% of cases. The mothers who were not taking appropriate action included young mothers with low education level and those working outside the home. CONCLUSION Diarrhoea is common in children less than two years old in Riyadh City, and intervention based in PHCCs needs to be undertaken to correct the faulty practices of mothers during diarrhoeal episodes in their children. Health education messages should emphasise feeding during diarrhoeal episodes.

Abstract
This paper uses the 1995 Guatemalan Survey of Family Health (EGSF) to analyze the relationship between child illness and health seeking behavior. The EGSF contains detailed calendar data on the nature and timing of illness and treatment behavior for children age five and below; extensive information about the characteristics of mothers, families and communities; and data on the accessibility of traditional and biomedical providers within and near the community. The analysis is based on 870 children who began a diarrheal or respiratory illness during a 2-week period prior to interview. Estimates are derived from a multinomial logit model of the probability of seeing a specific type of provider on a given day of illness, as a function of characteristics of the illness, child, mother, and community. The results indicate that modern medical care plays a major role in the treatment of infectious illness among children in rural Guatemala. The symptoms associated with the illness, their perceived severity, and mother's beliefs about their causes are important determinants of whether a child is brought to a provider and the type of provider visited. Poverty is a serious constraint on a family's choices about how to treat children's illnesses, whereas education and ethnicity have little effect on treatment behavior when income is held constant. In addition, the availability of modern health facilities within the community-both government-sponsored facilities and private doctors-has a substantial impact on the type of providers sought to treat children's illnesses.

Abstract
OBJECTIVE To investigate whether supplementation with vitamin A together with iron of Indonesian pregnant women decreases morbidity and improves growth of their infants during the first year of life. DESIGN Women from a rural area in West Java, Indonesia, were randomly assigned on an individual basis to double-blind supplementation once weekly from approximately 18 weeks of pregnancy until delivery. Supplementation comprised 120 mg iron and 500 microg folic acid with or without 4800 RE vitamin A. Their newborn infants were followed up during the first year of life: weight, length, morbidity and food intake were assessed monthly. RESULTS Infants whose mothers had taken vitamin A supplements during pregnancy had similar weight, length, weight gain and growth as their counterparts during the follow-up period. The proportions of infants with reported symptoms of morbidity were similar in the vitamin A plus iron group and the iron group. In addition immunisation coverage and feeding mode did not differ between the groups. All infants were breast-fed, but exclusive breast-feeding rapidly declined at 4 months of age. Infants with serum retinol concentrations >0.70 micromol/l increased their weight and length more during the first 6 months of life and had higher weight-for-age Z-scores during the first year of life than infants with serum retinol concentrations <or=0.70 micromol/l. Serum retinol concentrations were not associated with morbidity. CONCLUSION In this study, vitamin A supplementation in conjunction with iron supplementation of pregnant women did not improve growth or reduce morbidity of their infants during the first year of life.

Abstract
Self-reported schistosomiasis has been proven to be a reliable estimation of the prevalence of infection in school children. For the first time, this paper presents an investigation into the use of self-reported schistosomiasis to estimate the prevalence of urinary schistosomiasis, due to Schistosoma haematobium, in school children with particular emphasis on whether the age and sex of respondents influences the reliability of diagnosis. It is shown first, that the prevalence and intensity of infection vary with sex; infection in boys is always more prevalent and more intense than in girls of the same age and second, that age and sex influence the reliability of self-reported schistosomiasis as a diagnostic method. Age and sex are factors that should be considered when implementing control measures in endemic areas.

Abstract
This study examines the validity of a survey instrument on near-miss obstetric complications. Three groups of women--with severe complications, with mild complications, and with a normal delivery--were identified retrospectively in three hospitals in South Benin and interviewed at home. The concept of "near-miss" was used to identify women with severe episodes of morbidity. The questionnaire was able to detect, with some accuracy, eclamptic fits, abnormal bleeding in the third trimester for a recall period of at least three to four years, and all episodes of bleeding independent of timing within a period of two years. Questions concerning dystocia and infections of the genital tract generated disappointing results except when information on treatment was included. Overall, better results were achieved for antepartum and acute events. Severity made a positive difference only in the case of eclampsia, with an increase in sensitivity. The implications of the results for using women's recall of obstetric complications in surveys are discussed.

Abstract
Promotion of oral rehydration therapy (ORT) for the treatment of diarrheal diseases and the WHO case management strategy for acute respiratory infections (ARI) have contributed to significant reductions in infant mortality, but these two conditions remain the leading causes of infant deaths in most developing countries. Identification of the factors contributing to these deaths may contribute to reduce infant mortality from preventable causes. To gain insight into the circumstances and maternal and health services factors that may contribute to infant deaths we used a verbal autopsy method to interview mothers of all infants who died during the previous 12 months (June 1995-May 1996) in 11 municipalities in the State of Ceara, Northeast Brazil. Our results revealed that one-third of the deaths occurred in a hospital and two-thirds at home. Almost all the infants who died at home, however, had been examined one or more times by a doctor, and 36% of them had been hospitalized during the disease episode that resulted in death. For most (85%) of these children the causes of death were diarrhea or acute respiratory infection, and it is likely that death could have been averted if appropriate treatment had been initiated promptly. Three major groups of factors that alone or in combination appeared to contribute to most deaths were delays in seeking medical care on behalf of the parents, medical interventions reported as ineffective by mothers and delays in providing medical care to children who arrived at the hospital too late in the day to be scheduled for consultation. Our findings suggest that government efforts to further reduce infant mortality in Ceara should focus on health education interventions that address quality of home care, recognition of signs of severity and danger and importance of seeking timely medical care: and on improving the quality of care provided at community health centers and hospitals. Measures likely to improve infants' chance of survival include: ensuring prompt access to medical consultation for young children brought to health centers or hospitals with potentially life-threatening symptoms related to infections, health education to mothers on the need for continued home care after discharge and to return to the medical care facility if the child does not recover, and that they have access to medicine prescribed by hospital physicians. Further benefits could be obtained by using community health workers, now integrated into the Family Medicine Program (PSF) health teams, to provide health education, supervise home care, refer mothers to health centers and facilitate their access to hospitals.

Abstract
In rural Malawi, 703 newborns were visited monthly for 1 year to describe the epidemiology and health-seeking behaviour during acute episodes of diarrhoea, respiratory infections (ARI) and malaria. On average, the infants suffered from 1.3 annual episodes (11.0 illness days) of diarrhoea, 1.1 episodes (9.4 days) of ARI and 0.7 episodes (4.8 days) of malaria. Multivariate analysis with polychotomous logistic regression indicated that the amount of morbidity was associated with the child's area of residence, weight in early life, number of siblings, father's marital status and the source of drinking water. Diarrhoea and malaria were most common at 6-12 months of age and during the rainy months whereas respiratory infections peaked at 1-3 months of age and in the cold season. Ten per cent of diarrhoea, 9% of ARI and 7% of malaria episodes lasted for more than 14 days. Fifty-eight infants died, giving case fatality rates of 1% for diarrhoea, 2% for ARI and 4% for malaria. One-third (37%) of the illness episodes were managed at home without external advice. A traditional healer was consulted in 16% of episodes and a medical professional in 55% of episodes. If consulted, traditional healers were seen earlier than medical professionals (median duration after the onset of symptoms 0.7 vs. 1.8 days, P < 0.001). Traditional healers were significantly more commonly used by those families whose infants died than by those whose infants did not die (odds ratio 1.8, 95% CI 1.1, 3.0). Our results emphasise the influence of seasonality, care and living conditions on the morbidity of infants in rural Malawi. Case fatality for diarrhoea, ARI and malaria was high and associated with health-seeking behaviour among the guardians. Future interventions must aim at early and appropriate management of common childhood illnesses during infancy.

Abstract
Relying on data from the 1995 Guatemalan Survey of Family Health (EGSF), we analyse the relationship between child illness and health-seeking behaviour. Information on illness was collected for 3193 children. This analysis is based on 870 of these who became ill with diarrhoeal or respiratory disease during a 13-day period prior to interview. Estimates are derived from logistic models of the probability of seeing any or a specific type of health care provider as a function of characteristics of the illness on a given day and the child. The results indicate that modern medical care plays a major role in the treatment of infectious illness among children in rural Guatemala, with visits to pharmacists, doctors and the staff at government health facilities occurring much more frequently than visits to curers and other traditional practitioners. In general, families are much more likely to seek out a health care provider when a child experiences fever and gastrointestinal symptoms than when suffering from respiratory and other symptoms, and when a mother perceives the illness to be serious. The results also indicate that infants, low parity children, and children assessed as having generally been in good health are more likely to visit health care providers than other children. However, the particular associations often vary by type of health care provider.

Abstract
This paper uses a new calendar design implemented in the Guatemalan Survey of Family Health to analyze diarrheal and respiratory illness among children. The calendar provides a much richer description of child illness and treatment behavior than do conventional data typically collected in health interview surveys. The resulting estimates reveal that Guatemalan children experience high rates of diarrheal and respiratory illness and that these illnesses often involve multiple symptoms that only partially overlap one another. In addition, estimates from the calendar demonstrate that the measurement of illness frequency is fairly complex and that classification of illness into distinct categories may not always be feasible or meaningful. Results regarding treatment behavior indicate that the vast majority of illnesses are treated and that mothers almost always receive advice regarding their children's illnesses from relatives. On the other hand, health providers are sought for advice and treatment in only about one-third of illnesses. When families do seek providers, they are more likely to rely on biomedical ones - especially pharmacists, doctors and personnel at health posts and centers - than traditional practitioners. By far, the most common form of treatment - recommended by both relatives and providers - consists of readily available Western medicines. In contrast, the use of traditional remedies appears to be relatively low.

Abstract
This paper reports the validation of a 'best-judgement' standardised questionnaire using guidelines and algorithms developed by an expert working group conducted in Nicaragua between 1995 and 1997. Prospective hospital data, including standardised medical recording of selected signs and symptoms, laboratory and radiographic test results and physician diagnoses were collected for children < 5 years admitted with any serious life-threatening condition in 3 study hospitals. The mothers or caregivers of the children were later traced and interviewed using the 'best-judgement' questionnaire. Interviews were completed 1-22 months after admission to hospital for 1115 children (400 who died during the stay in hospital and 715 who were discharged alive). The cause of death or admission to hospital was determined by an expert algorithm applied to hospital data. A similar procedure was used to derive the cause using the answers to questions from interviews. Hospital causes were compared with interview causes and sensitivity and specificity calculated, together with the estimated cause-specific fraction for diarrhoea and pneumonia. Multiple diagnoses were allowed; 378 children in the sample (104 deaths, 274 survivors) had a reference diagnosis of diarrhoeal illness, and 506 (168 deaths, 338 survivors) a reference diagnosis of pneumonia. When results for deaths and survivors in all age groups were combined, the expert algorithms had sensitivity between 86% and 88% and specificity between 81% and 83% for any diarrhoeal illness; and sensitivity between 74% and 87% and specificity between 37% and 72% for pneumonia. Algorithms tested in previous validation studies were also applied to data obtained in this study, and the results are compared. Despite less than perfect sensitivity and specificity, reasonably accurate estimates of the cause-specific mortality and morbidity fractions for diarrhoea were obtained, although the accuracy of estimates in other settings using the same instrument will depend on the true cause-specific fraction in those settings. The algorithms tested for pneumonia did not produce accurate estimates of the cause-specific fraction, and are not recommended for use in community settings.

Abstract
In settings where most births occur at home, collection of data on complications experienced around the time of delivery is often dependent on self-reported data, collected through individual interviews. This paper describes a study designed to validate interview data on obstetric complications by comparing women's responses with data extracted from their medical records. The major complications of hemorrhage, dystocia, sepsis, and eclampsia were the main focus of the study. The sample was drawn from women hospitalized for delivery in a Manila hospital within the past 4 years. The main goal of the study was to assist in development of a survey instrument to be used in a national sample survey of women in the Philippines. The best sensitivity and specificity, respectively, for combinations of questions on these four conditions were: for hemorrhage, 0.70 and 0.78; for dystocia, 0.69 and 0.97; for sepsis, 0.89 and 0.83; and for eclampsia, 0.44 and 0.96. There were no significant differences in the duration of the recall periods according to diagnosis.

Abstract
Traditional measures of health status such as mortality rates and cause-of-death information give limited insight into the role of caregivers and health care providers in infant illness and death. To the extent that the behaviours of these parties can be accurately mapped, they may reveal important sites for effective community interventions and the improvement of medical care. This possibility is explored in relation to infant mortality in Cape Town, South Africa, by analysing verbal histories provided by the caregivers of 70 infants in the course of obtaining police death certification. From these verbal histories it appears that acute respiratory infection and diarrhoeal disease caused the majority of deaths. Infants with a respiratory condition were likely to have been taken for medical attention prior to death. By contrast, the parents of infants with diarrhoeal disease, while more active towards these infants, were less likely to seek medical care--these infants typically being found dead in bed or dying en route to the hospital or clinic. A story of infant death at home following recent medical care was obtained in over half the cases. This study demonstrates a simple method for the examination of the content and structure of lay accounts of illness and death. The implications for health care of such accounts are discussed in terms of the behavioural antecedents of infant mortality due to acute respiratory infections and diarrhoeal disease.

Abstract
Maternal education is one of the strongest determinants of infant survival in developing countries, however, questions remain regarding the extent to which its effects vary as a function of contextual variables. In this study, a multi-level interactive model is used to assess whether the protective effect of maternal education on the risk of infant diarrhea is modified by three aspects of the mother's familial and community environment: household assets, community economic resources and the availability of mothers' clubs. 2484 study participants were interviewed in 1984 as part of the Cebu Longitudinal Infant Health and Nutrition Study. The findings suggest that the protective effect of maternal education on infant diarrhea varies according to the socio-economic environment in which the mother lives: maternal education protects against infant diarrhea in the more economically and socially advantaged communities but has no effect in the more disadvantaged communities. The results also indicate that the protective effect of maternal education is smaller in the wealthier households. These data suggest that improvement in maternal education level, alone, may not always have the expected beneficial effects on infant health. Corollary measures to improve access of mothers and children to basic community resources and efforts to help mothers be more effective in their various social roles may be necessary preconditions for higher levels of maternal education to result in improved infant health.

Abstract
Although the association between nutritional status and mortality risk is obvious for extreme malnutrition, the issue is not so clear for mild to moderate undernutrition. We have investigated this association in children of 0-5 years in the rural area of Bwamanda, Zaire, where an integrated development project, with good medical facilities, has operated for 20 years. A random cluster sample of 5167 children was taken; newborn infants and immigrants were included at six quarterly survey rounds from October, 1989, until February, 1991. All surveys included clinical and anthropometric assessment of nutritional status. Deaths were recorded up to April, 1992; there were 246 deaths. Marasmus, kwashiorkor, and other causes of death were defined by the verbal autopsy method and checked against medical records kept at the central hospital and the peripheral dispensaries. As expected, we found an increased risk of death in severe malnutrition. When deaths directly attributed to marasmus or kwashiorkor were excluded, mild to moderate stunting or wasting were not associated with higher mortality in the short term (within 3 months of the previous study round) or in the long term (from 3-30 months after study entry). The commonest causes of death were malaria and anaemia. Extreme marasmus and kwashiorkor caused 16% of deaths, and are important causes of death even in this favoured area with an integrated development project. Nutritional interventions should be targeted more selectively so that children with moderate malnutrition can be protected from progression to marasmus or kwashiorkor.

Abstract
We describe the incidence of some childhood infections in drought prone areas of southern Ethiopia. Our results are based on 24 months' biweekly observations of 828 children aged 0-5 years in the pastoralist community of Dubluk and the agricultural community of Elka. An average of 23% of the children in Dubluk and 13% in Elka were sick during any 2-week period. Diarrhoeal diseases represented the main cause of morbidity, but the yearly number of diarrhoeal episodes were lower than previously reported from Ethiopia. Respiratory tract infections and to a lesser extent diarrhoeal diseases, showed highest incidence rates during the main dry season. The highest incidence of lower respiratory tract infections coincided with an outbreak of measles. In Dubluk, children who lived near to the wells had higher incidence rates than those who lived further away, probably reflecting the importance of crowding on transmission rates. In Elka, literacy of mothers was associated with reduced incidence of both diarrhoeal and respiratory tract infections, whereas the use of open pit latrines was associated with increased diarrhoeal incidence. The decline in disease incidence in this region during the last months of our study may reflect an improvement of nutritional status.
