Temporary Self-Deprivation Can Impair Cognitive Control: Evidence From the Ramadan Fast

During Ramadan, people of Muslim faith fast by not eating or drinking between sunrise and sunset. This is likely to have physiological and psychological consequences for fasters, and societal and economic impacts on the wider population. We investigate whether, during this voluntary and temporally limited fast, reminders of food can impair the fasters' reaction time and accuracy on a non-food-related test of cognitive control. Using a repeated measures design in a sample of Ramadan fasters (N = 190), we find that when food is made salient, fasters are slower and less accurate during Ramadan compared with after Ramadan. Control participants perform similarly across time. Furthermore, during Ramadan performances vary by how recently people had their last meal. Potential mechanisms are suggested, grounded in research on resource scarcity, commitment, and thought suppression, as well as the psychology of rituals and self-regulation, and implications for people who fast for religious or health reasons are discussed.

Religion, Fetal Protection, and Fasting during Pregnancy in Three Subcultures

Fasting during pregnancy is an enigma: why would a woman restrict her food intake during a period of increased nutritional need? Relative to the costs to healthy individuals who are not pregnant, the physiological costs of fasting in pregnancy are amplified, with intrauterine death being one possible outcome. Given these physiological costs, the question arises as to the socioecological factors that give rise to fasting during pregnancy. There has been little formal research regarding the emic perceptions and socioecological factors associated with such fasting. This study therefore took an emic approach and investigated the types of fasts that are common in pregnancy, women's perceptions of the consequences of fasting, and the socioecological models of pregnancy fasting in three Indian communities. This cross-sectional study took place in Bhubaneshwar, Odisha state, and Mysore, Karnataka state, among two populations of Hindu women and one population of Muslim women (N = 85). In total, 64% of women fasted in prior pregnancies. Findings revealed variation in the number and types of fasts that are common in pregnancy across the three communities. Each community reported differences in positive and negative consequences of fasting, with varied emphasis on reproductive health, religiosity, and general health and well-being. Finally, quantitative analyses indicated that the best-fitting model for fasting during pregnancy was religiosity, and the poorest-fitting models were resource scarcity and general health. This study provides insight into motivations for such fasting and highlights the need to investigate the relationship between supernatural beliefs and maternal-fetal protection further, as well as social functions of pregnancy fasting within the family and community.

The Role of Resources in the Success or Failure of Diverse Teams: Resource Scarcity Activates Negative Performance-Detracting Resource Dynamics in Social Category Diverse Teams

Increasing the social category diversity of work teams is top of mind for many organizations. However, such efforts may not always be sufficiently resourced, given the numerous resource demands facing organizations. In this paper, we offer a novel take on the relationship between social category diversity and team performance, seeking to understand the role resources may play in both altering and explaining the performance dynamics of diverse teams. Specifically, our resource framework explains how the effects of social category diversity on team performance can be explained by intrateam resource cognitions and behaviors and are dependent on team resource availability. We propose that in the face of scarcity in a focal resource (i.e., budget), diverse (but not homogenous) teams generalize this scarcity perception to fear that all resources (i.e., staff, time, etc.) are scarce, prompting performance-detracting power struggles over resources within the team. We find support for our model in three multimethod team-level studies, including two laboratory studies of interacting teams and a field study of work teams in research and development firms. Our resource framework provides a new lens to study the success or failure of diverse teams by illuminating a previously overlooked danger in diverse teams (negative resource cognitions (scarcity spillover bias) and behaviors (intrateam power struggles)), which offers enhanced explanatory power over prior explanations. This resource framework for the study of team diversity also yields insight into how to remove the roadblocks that may occur in diverse teams, highlighting the necessity of resource sufficiency for the success of diverse teams.

Context Matters for Food Security: Multi-Sited Evidence of Shared Cultural Models of Food Consumption

Anthropologists have long emphasized the social significance of foods and the contexts in which they are consumed. Expanding on this idea, we define the context of consumption as the non-eating behaviors that surround eating, such as the manner of food preparation, food sharing, and dietary patterns. In this study, we used cultural consensus analysis to assess whether there exist consistently shared, normative ideas about preferable context of food consumption in three diverse research sites: urban Ethiopia, rural Brazil, and rural Haiti. Our analysis demonstrates that in all three communities, there are distinct sets of behaviors that people identified as non-preferable because they reliably associate them with poverty and food insecurity, and behaviors that people identify as preferable because they reliably associate them with wealth and food security. Across the settings, there was little variation in agreement about behaviors across household composition, age, gender, and food security status. These findings suggest that people do indeed share culturally specific ideas about the context in which foods should be prepared and consumed, beyond the actual content of one's diet. Exploring these cultural models elucidates the social consequences of food insecurity, enabling researchers to better examine the relationship between food insecurity, social context, and well-being.

Pregnancy Fasting in Ramadan: Toward a Biocultural Framework

Pregnancy fasting poses a paradox: why would a woman restrict her diet during a period of increased nutritional need? This qualitative, cross-sectional study applied biological and cultural evolutionary theories of pregnancy diet to emic models of fasting with the aim of establishing a testable biocultural framework of pregnancy fasting. The research took place with Muslim women residing in Mysore, India. In-depth interviews were conducted with pregnant women who have experience and knowledge of fasting during during the holy month of Ramadan. Our findings indicate that pregnancy fasting is socially acquired via multiple modes of transmission and that women do not fast according to mainstream evolutionary theories of pregnancy diet, but perhaps to gain moral capital.

The Agro-Meteorological Caused Famines as an Evolutionary Factor in the Formation of Civilisation and History: Representative Cases in Europe

Throughout history, food adequacy has been one of the most critical parameters for the survival of human societies. The prevailing atmospheric conditions have always been recognised as the primary and most uncontrolled factors that determine crop production, both quantitatively and qualitatively. However, this is only a part of the effects chain. In order to assess the magnitude of the potential cultural impacts of weather changes in a region, it is crucial to comprehend the underlying mechanism of successive consequences that relate the proximate causes, which in our case are the adverse Agro-Meteorological Conditions (AMC), to their effects on society. The present study focuses on the analysis of the impacts’ mechanism on human societies. Moreover, several characteristic agro-meteorological events that have led to significant changes in European civilisation are presented as case studies. The results highlight the linkage between weather and its impact on history evolution based on Agro-Meteorological Famine (AMF). The proposed concept and its analysis by the schematic presentation are in corroboration with the documented historical events of European history. Moreover, the presented connections between weather, agricultural production, and society revealed the significant contribution of the short-term adverse weather conditions on the mechanism of the human civilisation evolution.

Climate Change: Expanding Anthropological Possibilities

Climate anthropology has broadened over the past decade from predominately locally focused studies on climate impacts to encompass new approaches to climate science, mitigation, sustainability transformations, risks, and resilience. We examine how theoretical positionings, including from actor–network theory, new materialisms, ontologies, and cosmopolitics, have helped expand anthropological climate research, particularly in three key interrelated areas. First, we investigate ethnographic approaches to climate science knowledge production, particularly around epistemic authority, visioning of futures, and engagements with the material world. Second, we consider climate adaptation studies that critically examine discourses and activities surrounding concepts of vulnerability, subjectivities, and resilience. Third, we analyze climate mitigation, including energy transitions, technological optimism, market-based solutions, and other ways of living in a carbon-constrained world. We conclude that anthropological approaches provide novel perspectives, made possible through engagements with our uniquely situated research partners, as well as opportunities for opening up diverse solutions and possible transformative futures.

Yersinia pestis strains from Latvia show depletion of the pla virulence gene at the end of the second plague pandemic

Ancient genomic studies have identified Yersinia pestis (Y. pestis) as the causative agent of the second plague pandemic (fourteenth–eighteenth century) that started with the Black Death (1,347–1,353). Most of the Y. pestis strains investigated from this pandemic have been isolated from western Europe, and not much is known about the diversity and microevolution of this bacterium in eastern European countries. In this study, we investigated human remains excavated from two cemeteries in Riga (Latvia). Historical evidence suggests that the burials were a consequence of plague outbreaks during the seventeenth century. DNA was extracted from teeth of 16 individuals and subjected to shotgun sequencing. Analysis of the metagenomic data revealed the presence of Y. pestis sequences in four remains, confirming that the buried individuals were victims of plague. In two samples, Y. pestis DNA coverage was sufficient for genome reconstruction. Subsequent phylogenetic analysis showed that the Riga strains fell within the diversity of the already known post-Black Death genomes. Interestingly, the two Latvian isolates did not cluster together. Moreover, we detected a drop in coverage of the pPCP1 plasmid region containing the pla gene. Further analysis indicated the presence of two pPCP1 plasmids, one with and one without the pla gene region, and only one bacterial chromosome, indicating that the same bacterium carried two distinct pPCP1 plasmids. In addition, we found the same pattern in the majority of previously published post-Black Death strains, but not in the Black Death strains. The pla gene is an important virulence factor for the infection of and transmission in humans. Thus, the spread of pla-depleted strains may, among other causes, have contributed to the disappearance of the second plague pandemic in eighteenth century Europe.

Water borrowing is consistently practiced globally and is associated with water-related system failures across diverse environments

Water problems due to scarcity, inaccessibility, or poor quality are a major barrier to household functioning, livelihood, and health globally. Household-to-household water borrowing has been posited as a strategy to alleviate unmet water needs. However, the prevalence and predictors of this practice have not been systematically examined. Therefore, we tested whether water borrowing occurs across diverse global contexts with varying water problems. Second, we tested if household water borrowing is associated with unmet water needs, perceived socio-economic status (SES), and/or water-related system failures, and if water access moderated (or changed) these relationships. Using survey data from the Household Water Insecurity Experiences (HWISE) study from 21 sites in 19 low- and middle-income countries (n = 5495 households), we found that household-to-household water borrowing was practiced in all 21 sites, with 44.7% (11.4-85.4%) of households borrowing water at least once the previous month. Multilevel mixed-effect logistic regression models demonstrate that high unmet water needs (odds ratio [OR] = 2.86], 95% confidence interval [CI] = 2.09-3.91), low perceived SES (OR = 1.09; 95% CI = 1.05-1.13), and water-related system failures (23-258%) were all significantly associated with higher odds of water borrowing. Significant interactions (all p < 0.01) between water access, unmet water needs, and water-related system failures on water borrowing indicate that water access moderates these relationships. These data are the first to demonstrate that borrowing water is commonly used by households around the world to cope with water insecurity. Due to how prevalent water borrowing is, its implications for social dynamics, resource allocation, and health and well-being are likely vast but severely under-recognized.

Hunger Affects Social Decisions in a Multi-Round Public Goods Game but Not a Single-Shot Ultimatum Game

Objective

People have the intuition that hunger undermines social cooperation, but experimental tests of this have often produced null results. One possible explanation is that the experimental tasks used are not rich enough to capture the diverse pathways by which social cooperation can be sustained or break down in real life. We studied the effects of hunger on cooperation in two tasks of differential interaction richness.

Methods

We manipulated hunger by asking participants to eat, or refrain from eating, breakfast. Participants in experiment 1 (n = 106) played a one-shot Ultimatum Game. Participants in experiment 2 (n = 264) played twenty rounds of a Public Goods Game in the same groups of four, ten rounds with the possibility of punishing other group members, and ten without.

Results

In experiment 1, skipping breakfast had no significant effects on either amounts proposed or minimum acceptable offers. In experiment 2, there were multiple different significant effects of the manipulation. No-breakfast participants were more generous in the first round of the game without punishment, and in subsequent rounds, were more influenced by what other group members had done the round before. In the punishment game, no-breakfast participants were also less likely to punish their group-mates than breakfast participants. Consequently, the possibility of punishment was less effective in increasing group cooperation levels in no-breakfast groups.

Conclusion

Replicating earlier findings, we found a null effect of hunger on cooperation in a one-shot Ultimatum Game. However, in our richer Public Goods Game, the dynamics of cooperation differed with hunger, in subtle ways not simply classifiable as hungry participants being ‘more’ or ‘less’ cooperative overall.

Generosity among the Ik of Uganda

According to Turnbull's 1972 ethnography The Mountain People, the Ik of Uganda had a culture of selfishness that made them uncooperative. His claims contrast with two widely accepted principles in evolutionary biology, that humans cooperate on larger scales than other species and that culture is an important facilitator of such cooperation. We use recently collected data to examine Ik culture and its influence on Ik behaviour. Turnbull's observations of selfishness were not necessarily inaccurate but they occurred during a severe famine. Cooperation re-emerged when people once again had enough resources to share. Accordingly, Ik donations in unframed Dictator Games are on par with average donations in Dictator Games played by people around the world. Furthermore, Ik culture includes traits that encourage sharing with those in need and a belief in supernatural punishment of selfishness. When these traits are used to frame Dictator Games, the average amounts given by Ik players increase. Turnbull's claim that the Ik have a culture of selfishness can be rejected. Cooperative norms are resilient, and the consensus among scholars that humans are remarkably cooperative and that human cooperation is supported by culture can remain intact.

Environmental Concerns and International Migration

This article focuses on international migration occurring as a result of environmental changes and processes. It briefly reviews attempts to conceptualize environment-related migration and then considers the extent to which environmental factors have been and may be significant in initiating migration. Following is an examination of migration as an independent variable in the migration-environment relationship. Finally, ethical and policy dimensions are addressed.

Nutrition and Care of Young Children during Emergencies

Emergencies are not only sudden events with natural causes that can be ameliorated with resources from outside. The causes and consequences of emergencies with sudden or slow onset, those that are complex and involve conflict, or are permanent emergencies are all deeply rooted in the vulnerability of people to hazards and their incapacity to recover. This will have implications for care behaviours and practices in the feeding, health, hygiene, and psychosocial areas. Families react to slow-onset emergencies by managing a declining resource with inevitable negative impacts on child care. Food intake declines. At the extreme of destitution, families may migrate to refugee camps where children face health crises as large displaced populations congregate around contaminated water sources. Breastfeeding may cease. In war situations, children face extreme psychosocial stresses. The importance of care for young children is given insufficient attention by those providing assistance from outside. Care interventions should improve the effectiveness of health, food, and psychosocial support

Family and Social Context Contributes to the Interplay of Economic Insecurity, Food Insecurity, and Health

In this study, we show how household health, economic instability, and food insecurity are inextricably linked; disruptions in individual health or income create cumulative and interdependent challenges faced by multiple household members. Drawing upon semi-structured focus groups with English- and Spanish-speaking clients of an urban food pantry, we demonstrate: (1) the impact of economic scarcity on health, (2) the impact of one household member's health on the health and food security of all household members, and (3) food sharing behaviors among family and social networks, including multi-generational families and non-kin individuals. We identify the gap between household-level assessments of food insecurity and individual-level health reports, which may obscure poor health among other household members. Understanding the social and family context of health and food insecurity may inform future interventions that address the interrelated challenges of diverse and disadvantaged households and communities.

The Great Irish Famine: Identifying Starvation in the Tissues of Victims Using Stable Isotope Analysis of Bone and Incremental Dentine Collagen

The major components of human diet both past and present may be estimated by measuring the carbon and nitrogen isotope ratios (δ¹³C and δ¹⁵N) of the collagenous proteins in bone and tooth dentine. However, the results from these two tissues differ substantially: bone collagen records a multi-year average whilst primary dentine records and retains time-bound isotope ratios deriving from the period of tooth development. Recent studies harnessing a sub-annual temporal sampling resolution have shed new light on the individual dietary histories of our ancestors by identifying unexpected radical short-term dietary changes, the duration of breastfeeding and migration where dietary change occurs, and by raising questions regarding factors other than diet that may impact on δ¹³C and δ¹⁵N values. Here we show that the dentine δ¹³C and δ¹⁵N profiles of workhouse inmates dating from the Great Irish Famine of the 19th century not only record the expected dietary change from C₃ potatoes to C₄ maize, but when used together they also document prolonged nutritional and other physiological stress resulting from insufficient sustenance. In the adults, the influence of the maize-based diet is seen in the δ¹³C difference between dentine (formed in childhood) and rib (representing an average from the last few years of life). The demonstrated effects of stress on the δ¹³C and δ¹⁵N values will have an impact on the interpretations of diet in past populations even in slow-turnover tissues such as compact bone. This technique also has applicability in the investigation of modern children subject to nutritional distress where hair and nails are unavailable or do not record an adequate period of time.

Local perceptions of cholera and anticipated vaccine acceptance in Katanga province, Democratic Republic of Congo

Background

In regions where access to clean water and the provision of a sanitary infrastructure has not been sustainable, cholera continues to pose an important public health burden. Although oral cholera vaccines (OCV) are effective means to complement classical cholera control efforts, still relatively little is known about their acceptability in targeted communities. Clarification of vaccine acceptability prior to the introduction of a new vaccine provides important information for future policy and planning.

Methods

In a cross-sectional study in Katanga province, Democratic Republic of Congo (DRC), local perceptions of cholera and anticipated acceptance of an OCV were investigated. A random sample of 360 unaffected adults from a rural town and a remote fishing island was interviewed in 2010. In-depth interviews with a purposive sample of key informants and focus-group discussions provided contextual information. Socio-cultural determinants of anticipated OCV acceptance were assessed with logistic regression.

Results

Most respondents perceived contaminated water (63%) and food (61%) as main causes of cholera. Vaccines (28%), health education (18%) and the provision of clean water (15%) were considered the most effective measures of cholera control. Anticipated vaccine acceptance reached 97% if an OCV would be provided for free. Cholera-specific knowledge of hygiene and self-help in form of praying for healing were positively associated with anticipated OCV acceptance if costs of USD 5 were assumed. Conversely, respondents who feared negative social implications of cholera were less likely to anticipate acceptance of OCVs. These fears were especially prominent among respondents who generated their income through fishing. With an increase of assumed costs to USD 10.5, fear of financial constraints was negatively associated with anticipated vaccine acceptance as well.

Conclusions

Results suggest a high motivation to use an OCV as long as it seems affordable. The needs of socially marginalized groups such as fishermen may have to be explicitly addressed when preparing for a mass vaccination campaign.

Perspectives on family and fertility in developing countries

Abstract Two aspects of the family in relation to fertility in developing countries are discussed: set stratification within the family and extended family networks. As both these are central to J. C. Caldwell's theory of fertility transition, the paper is structured as a critique of his position. Drawing on examples and data from Asia, it is argued that the causal significance of sex stratification for fertility lies in the economic risks it imposes on women, deriving from their dependence on men, rather than, as Caldwell suggests, in the disproportionate gain that men derive from their dominant position within families. While Caldwell and others associate strong extended family networks of mutual obligation and support with persistent high fertility, it is argued here that such systems should, instead, facilitate fertility decline. Close-knit and strong kin networks can be viewed as alternatives to children as sources of insurance, and may facilitate fertility decline by preventing children from becoming the focal point of parental concerns for security.

Altered social cohesion and adverse psychological experiences with chronic food insecurity in the non-market economy and complex households of Burkina Faso

Food insecurity negatively impacts outcomes in adults and children including parenting practices, child development, educational achievement, school performance, diet, and nutritional status. Ethnographic and quantitative research suggests that food insecurity affects well-being not only through the lack food, poor diet, and hunger, but also through social and psychological consequences that are closely linked to it. These studies are limited in number, and have mostly been carried out in contexts with market economies where household access to food depends almost solely on income. This study considers the social and psychological experiences closely linked to food insecurity in northern Burkina Faso, a context marked by subsistence farming, chronic food insecurity with a strong seasonal pattern, and a complex social structure. A total of 33 men and women from ten households were interviewed in February 2001 using semi-structured interview guides. Data were analyzed following the principles of thematic analysis. Food insecurity is closely linked with consequences such as concern, worries, and anxiety that ultimately lead to weight and sleep loss. Food insecurity results in feelings of alienation (e.g., shame) and deprivation (e.g., guilt), and alters household cohesion leading to disputes and difficulties keeping children at home. Decisions made by household members to manage and cope with food insecurity are shaped by their fear of alienation and other cultural and social norms. These findings, although derived from data collected 10 years ago before the 2008 food and fuel crises, remain valid in the study context, and emphasize the importance of social and psychological consequences closely linked to food insecurity and their negative impact on the well-being at both individual and household levels in contexts of non-market economy and chronic food insecurity. Attention to these non-nutritional consequences will improve the design, implementation, and evaluation of food insecurity programs in this and similar contexts.

Household capacities, vulnerabilities and food insecurity: shifts in food insecurity in urban and rural Ethiopia during the 2008 food crisis

The global food crisis of 2008 led to renewed interest in global food insecurity and how macro-level food prices impact household and individual level wellbeing. There is debate over the extent to which food price increases in 2008 eroded food security, the extent to which this effect was distributed across rural and urban locales, and the extent to which rural farmers might have benefited. Ethiopia's food prices increased particularly dramatically between 2005 and 2008 and here we ask whether there was a concomitant increase in household food insecurity, whether this decline was distributed equally across rural, urban, and semi-urban locales, and to what extent pre-crisis household capacities and vulnerabilities impacted 2008 household food insecurity levels. Data are drawn from a random sample of 2610 households in Southwest Ethiopia surveyed 2005/6 and again in mid to late 2008. Results show broad deterioration of household food insecurity relative to baseline but declines were most pronounced in the rural areas. Wealthier households and those that were relatively more food secure in 2005/6 tended to be more food secure in 2008, net of other factors, and these effects were most pronounced in urban areas. External shocks, such as a job loss or loss of crops, experienced by households were also associated with worse food insecurity in 2008 but few other household variables were associated with 2008 food insecurity. Our results also showed that rural farmers tended to produce small amounts for sale on markets, and thus were not able to enjoy the potential benefits that come from greater crop prices. We conclude that poverty, and not urban/rural difference, is the important variable for understanding the risk of food insecurity during a food crisis and that many rural farmers are too poor to take advantage of rapid rises in food prices.

THE FORGOTTEN POPULATION? YOUTH, FOOD IN SECURITY, AND RISING PRICES: IMPLICATIONS FOR THE GLOBAL FOOD CRISIS

The global food crisis has led to increased interest in food insecurity and its causes and consequences. Much of the focus however has been on mothers and young children, with little attention paid to the possible impacts on the large population of youth in developing countries. The objectives of this paper are to (1) draw attention to the food insecurity experience of a forgotten population, youth; (2) test whether the prevalence of food insecurity among Ethiopian adolescents is increasing with the rising cost of foods; and (3) to identify some individual, household, temporal, and spatial predictors of vulnerability. Data are drawn from a baseline survey in 2006 and a follow-up survey round conducted in 2007 of an ongoing population-based longitudinal study of approximately 2,100 youth living in southwestern Ethiopia. Results show high levels of food insecurity among youth, a marked increase in the experience of food insecurity among youth, and a bias in vulnerability toward youth in the poorest households and in rural households. During the intersurvey period boys were also more likely than girls to become food insecure. This latter finding effectively eliminates the gender bias in food insecurity observed in the baseline survey. Youth who became food insecure between survey rounds were also more likely to report worse health in 2007 than in 2006. Collectively our results suggest that youth are not being adequately buffered from food insecurity, and that generalizations about the current food crisis may be too broad and, thus, misrepresent vulnerable groups. Future research should focus on how to best protect vulnerable youth from the experience of food insecurity and its consequences.

Children's autonomous food acquisition in Mexican shantytowns

Children's independent food-acquisition behaviors have been rarely studied outside of hunter-gatherer contexts, yet millions of children worldwide search, work, trade, or beg for food. This study uses observational, anthropometric, dietary, and ethnographic data to understand preliminarily the nutritive and possible social contexts of autonomous middle childhood food-gaining behaviors in Mexican shantytowns. While we find children forage, work for, and share considerable amounts of food outside the household, this is not associated with significant variation in their anthropometric status or dietary quality; some possible social benefits of food-getting are, however, evident.

Seasonal changes in household food insecurity and symptoms of anxiety and depression

There is growing awareness that common mental health disorders are key contributors to the burden of disease in developing countries. Studies examining the correlates of mental health have primarily been carried out in urban settings and focused on the burden rapid economic change places on individuals. In these settings, poverty and low education are consistent predictors of anxiety and depressive symptoms. We argue here that these variables are proxies for insecurity, and that a more general model of symptoms of depression and anxiety should focus on locally salient forms of insecurity. Building on previous work in a seasonal subsistence setting, we identify food insecurity as a potent source of insecurity in a rural African setting, and then test whether seasonal changes in food insecurity are correlated with concomitant changes in a measure of symptoms of anxiety and depression among 173 caretakers. Results indicate that food insecurity is a strong predictor of symptoms of anxiety and depression (P < 0.0001), that changes in food insecurity across the seasons predict changes in symptoms of anxiety and depression (P < 0.0001), and that this is robust to the inclusion of covariates for material assets and household production. These results hold for individuals in both ethnic groups studied (Pimbwe and Sukuma); however, at the group level the burden falls disproportionately on Pimbwe. The results add to the growing literature on the causes of population level differences in mental health disorders and suggest new research avenues and strategies to link mental health disorders with variation in physical and biosocial outcomes.

Gender bias in the food insecurity experience of Ethiopian adolescents

Food insecurity is a pressing public health concern in many developing countries. Despite widespread interest in the sociocultural determinants of food insecurity, little is known about whether youths living in food insecure households experience food insecurity. The buffering hypothesis reviewed here assumes that, to the extent possible, adult members of households will buffer younger household members from the ill effects of food insecurity. A variant of the buffering hypothesis argues that only certain members of the households will enjoy the benefits of buffering. We hypothesize that within the context of Ethiopia, where girls have historically experienced discrimination, buffering is preferentially aimed at boys, especially as the household experiences greater levels of food stress. These hypotheses are tested using data from a population-based study of 2084 adolescents living in southwestern Ethiopia. Results indicate that boys and girls were equally likely to be living in severely food insecure households. Despite no differences in their households' food insecurity status, girls were more likely than boys to report being food insecure themselves. This gender difference was the largest in severely food insecure households. This same pattern was observed when comparing male-female sibling pairs living in the same household. These results are among the first to show that household level measures of food insecurity predict adolescent experiences of food insecurity, and that in the Ethiopian socio-cultural context, the relationship between household level food insecurity and adolescent food insecurity varies by gender. We also show that adolescent food insecurity is strongly associated with measures of general health and well-being.

Food insecurity in rural Tanzania is associated with maternal anxiety and depression

Food insecurity is a major health problem that has pervasive effects on many human biological outcomes. In particular, there are compelling theoretical and empirical reasons to expect that the relationship between food insecurity may be directly related to mental health morbidities, and may be quantifiable in developing country settings. This preliminary study examined whether caretaker reports of food insecurity were associated with anxiety and depression among four ethnic groups in two communities of rural Tanzania. In-home interviews were conducted in June-August of 2005 among female caretakers (n = 449). In addition to collecting household and demographic data, modified versions of the USDA's food security module and Hopkins Symptom Checklist (HSCL) were used to measure food insecurity and anxiety and depression. Consistent with predictions, the results showed a strong positive correlation between a caretaker's score on the food insecurity instrument and her summed response on the HSCL (P < 0.0001). This association was maintained in all four ethnic groups, even when controlling for individual-level covariates such as caretaker's age and marital status. Issues of causality and hypotheses that might explain this robust finding are discussed, as are methodological and theoretical implications.

ANTHROPOLOGICAL RESEARCH ON HAZARDS AND DISASTERS

▪ Abstract  Recent perspectives in anthropological research define a disaster as a process/event involving the combination of a potentially destructive agent(s) from the natural and/or technological environment and a population in a socially and technologically produced condition of vulnerability. From this basic understanding three general topical areas have developed: (a) a behavioral and organizational response approach, (b) a social change approach, and (c) a political economic/environmental approach, focusing on the historical-structural dimensions of vulnerability to hazards, particularly in the developing world. Applied anthropological contributions to disaster management are discussed as well as research on perception and assessment of hazard risk. The article closes with a discussion of potentials in hazard and disaster research for theory building in anthropology, particularly in issues of human-environment relations and sociocultural change.

Coping with drought and food insecurity in ethiopia

In this article I examine the impact of drought on farm households in Ethiopia and their response to crisis conditions. I ask whether every household in a community is equally affected by drought and what households do to mitigate the effects of drought and associated food insecurity. Information on production, income and food consumption is disaggregated by agroecological zone (highland and lowland), and by socioeconomic strata (relatively wealthy versus poor). Such detailed analysis permits an improved understanding of why the poor are much more vulnerable than the wealthy to drought and associated famines and why they need to be more effectively targeted by relief and development interventions. In a world of limited public resources for crisis intervention, such understanding is crucial to the design of improved policies and projects for reaching people most at risk.

Nutritional determinants of high-altitude growth in Nuñoa, Peru

Data on nutritional intake and patterns of physical growth in the rural Andean community of Nuñoa, Peru (elevation 4,000 m), are described and compared to data previously collected from this location. Food consumption data and selected anthropometric measures were obtained from a sample of 33 households. Estimates of caloric intake from this study are very similar to those obtained in Nuñoa during the mid- and late 1960s. However, within the present sample, upper income (i.e., middle class) individuals have significantly higher caloric intakes than those of the lower income group and also appear to have an improved diet relative to individuals of 20 years ago. Anthropometric data show that children of the upper socioeconomic status (SES) group are significantly taller and heavier than the lower SES group children. Moreover, the children of the wealthier families are taller and heavier than the children measured 20 years ago at the same location, whereas the poorer children are not. These results indicate that nutritional factors have significantly contributed to the extreme pattern of slow growth previously reported for children of Nuñoa and, moreover, demonstrate how social and environmental forces interact to create differential levels of stress that contribute to variation in biological well-being.

The Food and Nutrition Surveillance Systems of Chad and Mali: The "SAP" After Two Years

The "Systèmes d'Alerte Précoce" - the SAPs - of Chad and Mali have been in operation since April 1986. Their purpose is to forecast (or more realistically, detect as early as possible) food shortages in the drought-prone areas of each country. They are based on a multidisciplinary strategy, taking into account all relevant phenomena, from meteorology to nutritional status, and are implemented through the governmental networks. The present experience shows that, compared with the devastations due to famine and the cost of emergency food aid, they are not that expensive and they seem sustainable over the long term. "Faultless" prediction is not yet the rule, but several procedures permit progressive improvement in the ability of the systems to analyse and interpret. This paper explains the functioning process of the SAPs and presents several operational results. Additionally, it covers innovative concepts that have proved to be successful, such as the "participative information network".

The significance of drought, disease and famine in the agriculturally marginal zones of West-Central Africa

Some 170 references to drought and disease along the south-western coast of Central Africa between 1550 and 1830 suggest that climatic and epidemiological factors motivated the farmers and herders of West-Central Africa in historically significant ways. Nearly all references come from documentary sources and so bear primarily on conditions in the drier and less fertile areas near Luanda and to the south, where African reactions would have been strongest.

While minor shortages of rain occurred too frequently to receive much explicit attention in the documents, longer droughts spread more widely every decade or so and attracted notice. Major periods of dryness, extending for seven years or more and touching all parts of the region, occurred perhaps once each century and produced comments throughout the documentation.

Localized minor droughts hardly disrupted the lives of Africans, who had presumably devised agricultural and pastoral strategies to take account of such ordinary climatic variation. Two-or three-year rainfall shortages produced banditry and warfare that often attracted Portuguese military retaliation. Major droughts disrupted polities and societies and hence coincided with major turning points in West-Central African history in the late sixteenth and late eighteenth centuries. In the earlier case, agricultural failures produced the famed ‘Jaga’ or Imbangala warriors, who elevated pillage to a way of life and who joined the Portuguese in establishing the Angolan slave trade. The later, protracted drought from 1784 to 1793 coincided with the historic peak of slave exports from West-Central Africa.
