Food choice in transition: adolescent autonomy, agency, and the food environment.

Dietary intake during adolescence sets the foundation for a healthy life, but adolescents are diverse in their dietary patterns and in factors that influence food choice. More evidence to understand the key diet-related issues and the meaning and context of food choices for adolescents is needed to increase the potential for impactful actions. The aim of this second Series paper is to elevate the importance given to adolescent dietary intake and food choice, bringing a developmental perspective to inform policy and programmatic actions to improve diets. We describe patterns of dietary intake, then draw on existing literature to map how food choice can be influenced by unique features of adolescent development. Pooled qualitative data is then combined with evidence from the literature to explore ways in which adolescent development can interact with sociocultural context and the food environment to influence food choice. Irrespective of context, adolescents have a lot to say about why they eat what they eat, and insights into factors that might motivate them to change. Adolescents must be active partners in shaping local and global actions that support healthy eating patterns. Efforts to improve food environments and ultimately adolescent food choice should harness widely shared adolescent values beyond nutrition or health.

A mixed methods assessment of knowledge, attitudes and practices related to aflatoxin contamination and exposure among caregivers of children under 5 years in western Kenya.

OBJECTIVE: Identifying factors that may influence aflatoxin exposure in children under 5 years of age living in farming households in western Kenya. DESIGN: We used a mixed methods design. The quantitative component entailed serial cross-sectional interviews in 250 farming households to examine crop processing and conservation practices, household food storage and consumption and local understandings of aflatoxins. Qualitative data collection included focus group discussions (N 7) and key informant interviews (N 13) to explore explanations of harvesting and post-harvesting techniques and perceptions of crop spoilage. SETTING: The study was carried out in Asembo, a rural community where high rates of child stunting exist. PARTICIPANTS: A total of 250 female primary caregivers of children under 5 years of age and thirteen experts in farming and food management participated. RESULTS: Study results showed that from a young age, children routinely ate maize-based dishes. Economic constraints and changing environmental patterns guided the application of sub-optimal crop practices involving early harvest, poor drying, mixing spoiled with good cereals and storing cereals in polypropylene bags in confined quarters occupied by humans and livestock and raising risks of aflatoxin contamination. Most (80 %) smallholder farmers were unaware of aflatoxins and their harmful economic and health consequences. CONCLUSIONS: Young children living in subsistence farming households may be at risk of exposure to aflatoxins and consequent ill health and stunting. Sustained efforts to increase awareness of the risks of aflatoxins and control measures among subsistence farmers could help to mitigate practices that raise exposure.

Social and economic factors influencing intrahousehold food allocation and egg consumption of children in Kaduna State, Nigeria.

Adequate intake of high-quality nutritious foods during infancy and early childhood is critical to achieving optimal growth, cognitive and behavioural development, and economic productivity later in life. Integrating high-quality and nutrient-dense animal source foods (ASFs), a major source of protein and micronutrients, into children's diets is increasingly considered essential to reducing the global burden of malnutrition in low- and middle-income countries. While eggs are an ASF that shows promise for mitigating child undernutrition, interventions promoting egg consumption among children have had mixed results in improving egg intake and child growth outcomes. As part of an evaluation of a demand creation campaign promoting egg consumption, qualitative research was carried out in September 2019 to assess sociocultural and household factors affecting egg intake among young children living in Kaduna State, Nigeria, where a thriving egg industry and childhood stunting rates of 50% exist. Methods included freelisting exercises (11), key informant interviews (11), in-depth interviews (25) and FGDs (4). Results illuminated cultural rules that restrict egg consumption among children living in low-income households. These rules and norms reflect social and economic valuations that foster male dominance in household decision-making and guide food purchasing and intrahousehold food allocation that allow men to consume eggs more regularly. Study results highlight sociocultural considerations when selecting food interventions to address child malnutrition in low-income contexts. Interventions encouraging increased consumption of ASFs, and specifically eggs in young children, should be informed by formative research to understand sociocultural norms and beliefs guiding egg consumption.

Using a gender lens to understand eating behaviours of adolescent females living in low-income households in Bangladesh.

Adolescence is a critical period characterized by rapid physical, psychological, and social development and growth. In Bangladesh, high rates of undernutrition persist among adolescent females living in low-income households. Prevalence of adolescent marriage and pregnancy is extremely high, with almost half of Bangladeshi women giving birth by 18 years of age. Qualitative research was carried out from April to June 2017 to examine individual, social, and environmental factors influencing eating behaviours of female adolescents between 15 and 19 years of age living in low-income families in urban and rural settings in Bangladesh. Methods included freelisting exercises (33), key informant interviews (11), in-depth interviews (24), direct observations (16), and focus group discussions (12). Findings show that household food insecurity necessitates adjustments in meal food quality and frequency. Gender norms prescribe that females receive small meal portions and make sacrifices in food consumption so that male family members can eat more. Work and school schedules cause long breaks between meal consumption, restricting food intake of adolescent females for extended periods. Gender discrimination and its manifestations likely amplify susceptibility to psychological stresses in adolescent females. An inferior social position makes adolescent females living in food insecure households vulnerable to undernutrition, with factors affecting food deprivation increasing as they approach childbearing. Policies to increase age of marriage and reduce adolescent pregnancy must continue. Programmes must ensure that school-going adolescents eat adequately during the school day. Prolonging school education and strengthening the economic viability of women should alter cultural expectations regarding marriage age and normative female roles.

In-depth assessment of snacking behaviour in unmarried adolescent girls 16-19 years of age living in urban centres of Java, Indonesia.

Adolescence is a critical period characterized by physical, social, and developmental changes that impact on health and eating behaviour. Indonesia is experiencing dramatic economic and infrastructural changes, causing greater access to the global food industry and media. This transition is influencing food intake trends, leading to new nutritional challenges in adolescent girls. Qualitative research was conducted between November 2016 and January 2017 in five urban sites in Java, Indonesia, to examine individual, social, environmental, and macrosystem factors affecting snacking behaviours in unmarried adolescent girls 16-19 years of age. Methods entailed 30 freelisting exercises, nine key informant interviews, and 16 in-depth interviews. Freelisting results identified over 200 snack foods, with the most salient processed convenience foods such as chips and cookies. Respondents typically snacked multiple times daily. Widespread availability of affordable and "tasty" snacks makes snack foods appealing meal substitutes. Snacks provide a distraction to boredom and loneliness and an enhancement to social gatherings. Girls exhibited limited understanding or concern about potential negative effects of snacking. Parents facilitate acquisition of nutrient-poor snacks, whereas friends exert pressure for routine consumption of snack foods. Social media infiltrated with promotions of eateries and snack foods is likely contributing to the preponderance of snack food consumption. Routine consumption of snack foods high in sugar, salt, and fat and skipping meals will likely have long-term consequences on the nutritional status and health of Indonesian adolescent girls. Findings underline the urgent need to develop contextually relevant, targeted behavioural change strategies to modify the potentially harmful eating and activity patterns of adolescent girls identified in this study and to curb the trajectory of overweight in urban Indonesia.

An examination of women experiencing obstetric complications requiring emergency care: perceptions and sociocultural consequences of caesarean sections in Bangladesh.

Little is known about the physical and socioeconomic postpartum consequences of women who experience obstetric complications and require emergency obstetric care (EmOC), particularly in resource-poor countries such as Bangladesh where historically there has been a strong cultural preference for births at home. Recent increases in the use of skilled birth attendants show socioeconomic disparities in access to emergency obstetric services, highlighting the need to examine birthing preparation and perceptions of EmOC, including caesarean sections. Twenty women who delivered at a hospital and were identified by physicians as having severe obstetric complications during delivery or immediately thereafter were selected to participate in this qualitative study. Purposive sampling was used for selecting the women. The study was carried out in Matlab, Bangladesh, during March 2008-August 2009. Data-collection methods included in-depth interviews with women and, whenever possible, their family members. The results showed that the women were poorly informed before delivery about pregnancy-related complications and medical indications for emergency care. Barriers to care-seeking at emergency obstetric facilities and acceptance of lifesaving care were related to apprehensions about the physical consequences and social stigma, resulting from hospital procedures and financial concerns. The respondents held many misconceptions about caesarean sections and distrust regarding the reason for recommending the procedure by the healthcare providers. Women who had caesarean sections incurred high costs that led to economic burdens on family members, and the blame was attributed to the woman. The postpartum health consequences reported by the women were generally left untreated. The data underscore the importance of educating women and their families about pregnancy-related complications and preparing families for the possibility of caesarean section. At the same time, the health systems need to be strengthened to ensure that all women in clinical need of lifesaving obstetric surgery access quality EmOC services rapidly and, once in a facility, can obtain a caesarean section promptly, if needed. While greater access to surgical interventions may be lifesaving, policy-makers need to institute mechanisms to discourage the over-medicalization of childbirth in a context where the use of caesarean section is rapidly rising.

Violence against women with chronic maternal disabilities in rural Bangladesh.

This study explored violence against women with chronic maternal disabilities in rural Bangladesh. During November 2006-July 2008, in-depth interviews were conducted with 17 rural Bangladeshi women suffering from uterine prolapse, stress incontinence, or fistula. Results of interviews showed that exposure to emotional abuse was almost universal, and most women were sexually abused. The common triggers for violence were the inability of the woman to perform household chores and to satisfy her husband's sexual demands. Misconceptions relating to the causes of these disabilities and the inability of the affected women to fulfill gender role expectations fostered stigma. Emotional and sexual violence increased their vulnerability, highlighting the lack of life options outside marriage and silencing most of them into accepting the violence. Initiatives need to be developed to address misperceptions regarding the causes of such disabilities and, in the long-term, create economic opportunities for reducing the dependence of women on marriage and men and transform the society to overcome rigid gender norms.

Effect of the Integrated Management of Childhood Illness strategy on childhood mortality and nutrition in a rural area in Bangladesh: a cluster randomised trial.

BACKGROUND: WHO and UNICEF launched the Integrated Management of Childhood Illness (IMCI) strategy in the mid-1990s to reduce deaths from diarrhoea, pneumonia, malaria, measles, and malnutrition in children younger than 5 years. We assessed the effect of IMCI on health and nutrition of children younger than 5 years in Bangladesh. METHODS: In this cluster randomised trial, 20 first-level government health facilities in the Matlab subdistrict of Bangladesh and their catchment areas (total population about 350 000) were paired and randomly assigned to either IMCI (intervention; ten clusters) or usual services (comparison; ten clusters). All three components of IMCI-health-worker training, health-systems improvements, and family and community activities-were implemented beginning in February, 2002. Assessment included household and health facility surveys tracking intermediate outputs and outcomes, and nutrition and mortality changes in intervention and comparison areas. Primary endpoint was mortality in children aged between 7 days and 59 months. Analysis was by intention to treat. This study is registered, number ISRCTN52793850. FINDINGS: The yearly rate of mortality reduction in children younger than 5 years (excluding deaths in first week of life) was similar in IMCI and comparison areas (8.6%vs 7.8%). In the last 2 years of the study, the mortality rate was 13.4% lower in IMCI than in comparison areas (95% CI -14.2 to 34.3), corresponding to 4.2 fewer deaths per 1000 livebirths (95% CI -4.1 to 12.4; p=0.30). Implementation of IMCI led to improved health-worker skills, health-system support, and family and community practices, translating into increased care-seeking for illnesses. In IMCI areas, more children younger than 6 months were exclusively breastfed (76%vs 65%, difference of differences 10.1%, 95% CI 2.65-17.62), and prevalence of stunting in children aged 24-59 months decreased more rapidly (difference of differences -7.33, 95% CI -13.83 to -0.83) than in comparison areas. INTERPRETATION: IMCI was associated with positive changes in all input, output, and outcome indicators, including increased exclusive breastfeeding and decreased stunting. However, IMCI implementation had no effect on mortality within the timeframe of the assessment.

An In-Depth Examination of Reasons for Autopsy Acceptance and Refusal in Northern Tanzania.

Uncertainty about the causes of death (COD) in low- and middle-income countries (LMICs) has been recognized as a constraint to global health and development. Although complete diagnostic autopsy (CDA) is the best way to assess COD, it is uncommon in LMICs because of low investment priority and assumptions about poor acceptability. Social science research was conducted from May 2016 through July 2017 to examine issues related to acceptability of CDAs in northern Tanzania where autopsy was being offered in two referral hospitals to assess COD associated with febrile illness. Initial formative research entailed 29 key informant interviews, seven observations of burial practices, and four group discussions. In-depth interviews were conducted with families of deceased, including nine families that accepted and 11 families that refused CDA. The formative research identified concepts related to death, understandings of CDA, and cultural practices and psychosocial considerations associated with death that informed the authorization process. Most families who accepted CDA cited the desire to get clarity regarding the COD as a primary reason for acceptance. An unexpected finding was that CDA is perceived as a means to determine witchcraft involvement, a common explanation for COD and a common reason for postmortem acceptance. Death resulting from chronic illness or conditions presumed to have a clinical diagnosis were reasons for CDA to be viewed as unnecessary. The timing, way families were approached, and content of information shared during authorization influenced acceptance and refusal of CDA. Findings show that CDAs can be acceptable in settings where traditional disease models prevail.

"If You Have No Money, You Might Die": A Qualitative Study of Sociocultural and Health System Barriers to Care for Decedent Febrile Inpatients in Northern Tanzania.

Infectious diseases are a leading cause of mortality in low- and middle-income countries (LMICs) despite effective treatments. To study the sociocultural and health system barriers to care, we conducted a qualitative social autopsy study of patients who died from febrile illness in northern Tanzania. From December 2016 through July 2017, we conducted in-depth interviews in Arusha and Kilimanjaro regions with a purposive sample of 20 family members of patients who had died at two regional referral hospitals. Of the deceased patients included in this study, 14 (70%) were adults and 10 (50%) were female. Patients identified their religion as Catholic (12, 60%), Lutheran (six, 30%), and Muslim (two, 10%), and their ethnicity as Chagga (14, 70%) and Sambaa (two, 10%), among others. Family members reported both barriers to and facilitators of receiving health care. Barriers included a perceived lack of capacity of local health facilities, transportation barriers, and a lack of formal referrals to higher levels of care. Family members also reported the cost of health care as a barrier. However, one facilitator of care was access to financial resources via families' social networks-a phenomenon we refer to as social capital. Another facilitator of care was families' proactive engagement with the health system. Our results suggest that further investment in lower level health facilities may improve care-seeking and referral patterns and that future research into the role of social capital is needed to fully understand the effect of socioeconomic factors on healthcare utilization in LMICs.

Postpartum haemorrhage and eclampsia: differences in knowledge and care-seeking behaviour in two districts of Bangladesh.

In high- and low-performing districts of Bangladesh, the study explored the demand-side of maternal healthcare by looking at differences in perceived knowledge and care-seeking behaviours of women in relation to postpartum haemorrhage or eclampsia. Haemorrhage and eclampsia are two major causes of maternal mortality in Bangladesh. The study was conducted during July 2006-December 2007. Both postpartum bleeding and eclampsia were recognized by women of different age-groups as severe and life-threatening obstetric complications. However, a gap existed between perception and actual care-seeking behaviours which could contribute to the high rate of maternal deaths associated with these conditions. There were differences in care-seeking practices among women in the two different areas of Bangladesh, which may reflect sociocultural differences, disparities in economic and educational opportunities, and a discrimination in the availability of care.

Programmatic implications for promotion of handwashing behavior in an internally displaced persons camp in North Kivu, Democratic Republic of Congo.

BACKGROUND: Diarrhea and acute respiratory infections (ARI) account for 30% of deaths among children displaced due to humanitarian emergencies. A wealth of evidence demonstrates that handwashing with soap prevents both diarrhea and ARI. While socially- and emotionally-driven factors are proven motivators to handwashing in non-emergency situations, little is known about determinants of handwashing behavior in emergency settings. METHODS: We conducted a qualitative investigation from June to August 2015 in a camp for internally displaced persons with a population of 6360 in the war-torn eastern region of the Democratic Republic of Congo. We held key informant interviews with 9 non-governmental organizations and camp officials, in-depth interviews and rating exercises with 18 mothers of children < 5 years, and discussions with 4 groups of camp residents and hygiene promoters to identify motivators and barriers to handwashing. RESULTS: At the time of the study, hygiene promotion activities lacked adequate resources, cultural acceptability, innovation, and adaptation for sustained behavioral change. Lack of ongoing provision of hygiene materials was a major barrier to handwashing behavior. When hygiene materials were available, camp residents reported that the primary motivator to handwashing was to prevent illness, particularly diarrheal disease, with many mentioning an increased need to wash hands during diarrhea outbreaks. Emotionally- and socially-related motivators such as "maintaining a good image" and social pressure to follow recommended camp hygiene practices were also reported to motivate handwashing with soap. Residents who engaged in day labor outside the camp had limited exposure to hygiene messages and handwashing facilities. Interviewees indicated that the harsh living conditions forced residents to prioritize obtaining basic survival needs over good hygiene. CONCLUSIONS: Hygiene promotion in camp settings must involve preparedness of adequate resources and supplies and ongoing provision of hygiene materials so that vulnerable populations affected by emergencies can apply good hygiene behaviors for the duration of the camp's existence. Compared to non-emergency contexts, illness-based messages may be more effective in emergency settings where disease poses a current and ongoing threat. However, failure to use emotive and social drivers that motivate handwashing may present missed opportunities to improve handwashing in camps.

Delivering Vitamin A Supplements to Children Aged 6-59 Months: Comparing Delivery through Campaigns and through Routine Health Services in Senegal.

BACKGROUND: Using twice-yearly campaigns such as Child Health Days to deliver vitamin A supplements has been a key strategy over the last 2 decades, and was an important component in helping reach the Millennium Development Goals in child health. As countries move to strengthen their routine health services under the Sustainable Development Goals, efforts are underway to shift supplementation from campaign to routine delivery. OBJECTIVE: The aim of this study was to compare cost, coverage, and user satisfaction between twice-yearly campaigns and routine delivery of vitamin A supplements in Senegal. METHODS: Information was collected on cost, coverage, and user satisfaction with both types of delivery, using administrative data, interviews at various levels in the health system, and focus group discussions with caregivers. Both qualitative and quantitative information were obtained, for 2 regions using routine delivery and 2 regions using campaign delivery. RESULTS: Routine delivery receives fewer dedicated resources. Coverage is lower, especially of children >12 mo of age. Districts undertake outreach ("mini-campaigns") to try to improve coverage in regions using routine delivery, in effect using a hybrid approach. Some mothers prefer the administration of supplements at a health facility as it is perceived as more hygienic and involving professional health workers, but others, especially those living further away, prefer house-to-house delivery which was the norm for the campaign mode. CONCLUSIONS: Advance planning for the shift to routine delivery is important in maintaining coverage, as is strengthening the primary health care system by having an appropriate ratio of salaried workers to population. When the system relies heavily on volunteers, and the small incentive payments to volunteers are discontinued, coverage suffers. Routine delivery also relies on good record-keeping and hence literacy. Community understanding of, and support for, supplementation are even more important for routine than for campaign delivery.

Equity in use of home-based or facility-based skilled obstetric care in rural Bangladesh: an observational study.

BACKGROUND: Few studies have assessed whether the poorest people in developing countries benefit from giving birth at home rather than in a facility. We analysed whether socioeconomic status results in differences in the use of professional midwives at home and in a basic obstetric facility in a rural area of Bangladesh, where obstetric care was free of charge. METHODS: We routinely obtained data from Matlab, Bangladesh between 1987 and 2001. We compared the benefits of home-based and facility-based obstetric care using a multinomial logistic and binomial log link regression, controlling for multiple confounders. FINDINGS: Whether or not a midwife was used at home or in a facility differed significantly with wealth (adjusted odds ratio comparing the wealthiest and poorest quintiles 1.94 [95% CI 1.69-2.24] for home-based care, and 2.05 [1.72-2.43] for facility-based care). The gap between rich and poor widened after the introduction of facility-based care in 1996. The risk ratio (RR) between the wealthiest and poorest quintiles was 1.91 (adjusted RR 1.49 [95% CI 1.16-1.91] when most births with a midwife took place at home compared with 2.71 (1.66 [1.41-1.96]) at the peak of facility-based care. INTERPRETATION: In this area of Bangladesh, a shift from home-based to facility-based basic obstetric care is feasible but might lead to increased inequities in access to health care. However, there is also evidence of substantial inequities in home births. Before developing countries reinforce home-based births with a skilled attendant, research is needed to compare the feasibility, cost, effectiveness, acceptability, and implications for health-care equity in both approaches.

Why Bangladeshi nurses avoid 'nursing': social and structural factors on hospital wards in Bangladesh.

In response to concerns that nurses spend less than 6% of their time on direct patient care, this study explored factors that influence nurses' behaviour in the provision of 'hands on' care in hospitals in Bangladesh. Through in-depth interviews with female nurses and patients and their co-workers in six hospitals, we identified conflicts between the inherited British model of nursing and Bangladeshi societal norms. This was most evident in the areas of night duty, contact with strangers, and involvement in 'dirty' work. The public was said to associate nursing activities with commercial sex work. As a consequence, their value on the 'bride market' decreases. To minimise the stigma associated with their profession, nurses in government hospitals distance themselves from patients, using nurse surrogates in the form of patients' relatives and hospital support workers to carry out their work. These adaptations are supported and sustained through unofficial activities developed over time within hospitals. In contrast nurses in NGO hospitals give more direct patient care themselves and do not rely on carers as much because of tight supervision and limited visitor hours. Initiatives undertaken to improve the quality of patient care, such as enlarging the nursing workforce or providing clinical instruction, which do not take into account the prevailing culture in hospitals and social conflicts faced by nurses, are unlikely to succeed. Fundamental decisions on how to care for the sick in Bangladesh are required. If the present nursing curriculum is followed, adequate supplies, supervision and accountability are prerequisites for its implementation.

Household costs of healthcare during pregnancy, delivery, and the postpartum period: a case study from Matlab, Bangladesh.

A household survey was undertaken in Matlab, a rural area of Bangladesh, to estimate the costs incurred during pregnancy, delivery, and the postpartum period for women delivering at home and in a health facility. Those interviewed included 121 women who delivered at home, 120 who delivered in an ICDDR,B basic obstetric care (BEOC) facility, 27 who delivered in a public comprehensive obstetric care (CEOC) hospital, and 58 who delivered in private hospitals. There was no significant difference in total costs incurred by those delivering at home and those delivering in a BEOC facility. Costs for those delivering in CEOC facilities were over nine times greater than for those delivering in BEOC facilities. Costs of care during delivery were predominant. Antenatal and postnatal care added between 7% and 30% to the total cost. Services were more equitable at home and in a BEOC facility compared to services provided at CEOC facilities. The study highlights the regressive nature of the financing of CEOC services and the need for a financing strategy that covers both the costs of referral and BEOC care for those in need.

Integrated Management of Childhood Illness (IMCI) in Bangladesh: early findings from a cluster-randomised study.

BACKGROUND: We report the preliminary findings from a continuing cluster randomised evaluation of the Integrated Management of Childhood Illness (IMCI) strategy in Bangladesh. METHODS: 20 first-level outpatient facilities in the Matlab sub-district and their catchment areas were randomised to either IMCI or standard care. Surveys were done in households and in health facilities at baseline and were repeated about 2 years after implementation. Data on use of health facilities were recorded. IMCI implementation included health worker training, health systems support, and community level activities guided by formative research. FINDINGS: 94% of health workers in the intervention facilities were trained in IMCI. Health systems supports were generally available, but implementation of the community activities was slow. The mean index of correct treatment for sick children was 54 in IMCI facilities compared with 9 in comparison facilities (range 0-100). Use of the IMCI facilities increased from 0.6 visits per child per year at baseline to 1.9 visits per child per year about 21 months after IMCI introduction. 19% of sick children in the IMCI area were taken to a health worker compared with 9% in the non-IMCI area. INTERPRETATION: 2 years into the assessment, the results show improvements in the quality of care in health facilities, increases in use of facilities, and gains in the proportion of sick children taken to an appropriate health care provider. These findings are being used to strengthen child health care nationwide. They suggest that low levels of use of health facilities could be improved by investing in quality of care and health systems support.

Cultural and social context of dysentery: implications for the introduction of a new vaccine.

Dysentery, a severe form of diarrhoeal disease, is a major cause of morbidity and mortality. Paradoxically, virtually no studies have been conducted to examine beliefs and behaviours associated with dysentery. The explanatory model of dysentery was explored in a community in Dhaka, Bangladesh, to understand the acceptability of a vaccine against dysentery. A local term for bloody dysentery is widely known, and residents describe a progression of symptoms, which closely mirrors the biomedical model of the disease. Due to the symbolic significance of blood loss and the fact that there is much uncertainty regarding treatment, bloody dysentery is perceived to be extremely serious. Causal interpretations most commonly relate to humoral theories, and remedies involve the consumption of 'cooling' foods that will reduce the heat associated with dysentery. Despite many misconceptions about vaccines and the fact that this approach contradicts aetiological explanations, the perceived severity of the illness makes vaccines attractive compared to other preventative measures. The results illuminate relevant information for the implementation of a new vaccine.

Coping with a nutrient deficiency: cultural models of vitamin A deficiency in northern Niger.

Cultural explanations and management strategies for specific signs and symptoms of vitamin A deficiency are explored in a Hausa-speaking community in northern Niger. Their interpretations of the etiology of nightblindness in young children and pregnant women focus on food-related causes, in which "lack of good food" is central. In parallel with the significance of food in the etiology of nightblindness, the recommended treatments are home food remedies, primarily involving liver, meat, or green leaves. The locally attributed etiology for the more severe manifestation of vitamin A deficiency, xerophthalmia, stands in sharp contrast to this. People believe the primary cause is "heat" produced by acute infectious disease (particularly measles). A trip to the medical dispensary or a reliance upon home remedies are the preferred treatment options for this condition. We explore the striking correspondence between local interpretations of nightblindness and contemporary medical knowledge and treatment in relation to the very different explanations and curative measures offered for more serious manifestations of vitamin A deficiency.

Formative investigation of acceptability of typhoid vaccine during a typhoid fever outbreak in Neno District, Malawi.

Typhoid fever affects an estimated 22 million people annually and causes 216,000 deaths worldwide. We conducted an investigation in August and September 2010 to examine the acceptability of typhoid vaccine in Neno District, Malawi where a typhoid outbreak was ongoing. We used qualitative methods, including freelisting exercises, key informant and in-depth interviews, and group discussions. Respondents associated illness with exposure to "bad wind," and transmission was believed to be airborne. Typhoid was considered extremely dangerous because of its rapid spread, the debilitating conditions it produced, the number of related fatalities, and the perception that it was highly contagious. Respondents were skeptical about the effectiveness of water, sanitation, and hygiene (WaSH) interventions. The perceived severity of typhoid and fear of exposure, uncertainty about the effectiveness of WaSH measures, and widespread belief in the efficacy of vaccines in preventing disease resulted in an overwhelming interest in receiving typhoid vaccine during an outbreak.
