Obesity is new in human evolutionary history, having become possible at the population level with increased food security. Across the past 60 years, social, economic, and technological changes have altered patterns of life almost everywhere on Earth. In tandem, changes in diet and physical activity patterns have been central to the emergence of obesity among many of the world's populations, including the developing world. Increasing global rates of obesity are broadly attributed to environments that are obesogenic, against an evolutionary heritage that is maladaptive in these new contexts. Obesity has been studied using genetic, physiological, psychological, behavioral, cultural, environmental, and economic frameworks. Although most obesity research is firmly embedded within disciplinary boundaries, some convergence between genetics, physiology, and eating behavior has taken place recently. This chapter reviews changing patterns and understandings of obesity from these diverse perspectives.

Over seventy per cent of the population in industrialized nations live in cities; soon, so will most of the world's population. This volume examines the impact of urban living on human health and biology. Cities pose numerous and diverse social and biological challenges to human populations which bear little resemblance to the forces that moulded human biology through millions of years of evolution. Urban populations in industrialized nations have distinctive patterns of behaviour, social stratification, stress, infectious disease, diet, activity and exposure to pollutants from years of industrialization. These features affect diverse aspects of human function including human nutrition, energy expenditure, growth and reproduction. This volume begins with an introduction to the history of urbanism and poverty, infectious disease, reproductive function, child health, nutrition, physical activity and psychosocial stress. The book will appeal to workers in urban planning, human biology, anthropology, preventative medicine, human ecology and related areas

Seasonality has effects on a wide range of human functions and activities, and is important in the understanding of human-environment relationships. In this volume, distinguished contributors including human biologists, anthropologists, physiologists and nutritionists consider many of the different ways in which seasonality influences human biology and behaviour. Topics addressed include the influence of seasonality on hominid evolution, seasonal climatic effects on human physiology, fertility and physical growth, seasonality in morbidity, mortality and nutritional state, and seasonal factors in food production, modernization and work organization in Third World economies. This book will be of interest to graduate students and researchers in human biology, anthropology and nutrition

This article argues for an affective approach to obesity that destabilizes the conceptual boundaries between the biological and the social aspects of food, eating, and fatness. Its approach foregrounds visceral experience, attends to food both inside and outside the body, and explores how bodies labeled "obese" consume their political, economic, and material environments. This approach is termed affective political ecology. The authors' aim is to draw attention to how the entanglements between the physiological and social aspects of eating tend to be absented from antiobesity public health rhetoric. By exploring a range of ethnographic examples in high-income countries, they illuminate how such interventions often fail to account for the complex interplays between subjective corporeal experience and political economic relations and contend that overlooking an individual's visceral relationship with food counterproductively augments social stigma, stresses, and painful emotions. They demonstrate, then, how an approach that draws together political economic and biomedical perspectives better reflects the lived experience of eating. In so doing, the authors aim to indicate how attending to affective political ecologies can further our understanding of the consumption practices of those in precarious and stressful social contexts, and they offer additional insight into how the entanglement of the biological and the social is experienced in everyday life.

Addresses the need for review and assessment of the framework of interdisciplinary population studies. It includes chapters on anthropology, archaeology, demography, ecology, epidemiology, geography, genomics, human biology, population genetics, social and demographic history, the history of science, and social network analysis.

Bourdieu suggested that the habitus contains the 'genetic information' which both allows and disposes successive generations to reproduce the world they inherit from their parents' generation. While his writings on habitus are concerned with embodied dispositions, biological processes are not a feature of the practical reason of habitus. Recent critiques of the separate worlds of biology and culture, and the rise in epigenetics, provide new opportunities for expanding theoretical concepts like habitus. Using obesity science as a case study we attempt to conceptualise the enfolding of biological and social processes (via a Deleuzian metaphor) to develop a concept of biohabitus – reconfiguring how social and biological environments interact across the life course, and may be transmitted and transformed intergenerationally. In conclusion we suggest that the enfolding and reproduction of social life that Bourdieu articulated as habitus is a useful theoretical frame that can be enhanced to critically develop epigenetic understandings of obesity, and vice versa.

In this article, we explore the discursive constructions of Buycott, a free mobile app that provides a platform for user-generated ethical consumption campaigns. Unlike other ethical consumption apps, Buycott's mode of knowledge production positions the app itself as neutral, with app users generating activist campaigns and providing both data and judgment. Although Buycott is not a dedicated food activism app, food features centrally in its campaigns, and the app seems to provide a mobile means of extending, and perhaps expanding, alternative food network (AFN) action across geographies and constituencies. Thus, as a case study, Buycott unveils contemporary possibilities for citizen participation and the formation of activist consumer communities, both local and trans-national, through mobile technologies. Our analysis shows, however, that despite the app's user-generated format, the forms of activism it enables are constrained by the app's binary construction of action as non/consumption and its guiding 'mission' of 'voting with your wallet'. Grounded in texts concerning Buycott's two largest campaigns (Demand GMO Labeling and Long live Palestine boycott Israel), our analysis delineates how Buycott, its campaigns, and its modes of action take shape in user, media, and app developer discourses. We find that, as discursively framed, Buycott campaigns are commodity-centric, invoking an 'ethics of care' to be enacted by atomized consumers, in corporate spaces and through mainstream, barcode-bearing, retail products. In user discourses, this corporate spatiality translates into the imagined materializing of issues in products, investing commodities with the substance of an otherwise ethereal cause. This individualized, commodity-centric activism reinforces tenets of the neoliberal market, ultimately turning individual users into consumers not only of products, but also of the app itself. Thus, we suggest, the activist habitus constructed through Buycott is a neoliberal, consumer habitus.

South Africa underwent major social and economic change between 1987 and 1995. The release of Nelson Mandela in February 1990 proclaimed an end to the political system of apartheid, and the first freely elected non-White government in 1994 instigated social and economic reforms aimed at alleviating the consequences of apartheid. This paper aims to examine the impact of these socio-economic and political changes on height, weight and body mass index (BMI) in childhood and late adolescence. An analysis was carried out of longitudinal data of 258 urban and rural South African Cape Coloured schoolchildren (6–18 years old) across the transitional periods from apartheid between 1987 and 1990, to this transition between 1991 and 1993, and finally to post-apartheid between 1994 and 1995. The anthropometric measures were standardized into age independent Z-scores. Analyses of variance with repeated measures were conducted to examine the growth in height, weight and BMI across these periods. The results show a significant main effect of measurement periods on height, weight and BMI Z-scores. Across time, the subjects increased in overall size, height, weight and BMI. For all the anthropometric measures there was a significant interaction effect between measurement period and sex, but none between measurement period and SES. The average increase in height, weight and BMI across time differed significantly for girls and boys, the average z-scores being greater in girls than in boys. For boys, there was little difference in height, weight and BMI Z-scores according to SES, and little increase across periods. Girls were generally taller, heavier with greater BMI than boys, and their scores increased across the time periods. High SES girls were taller, heavier and had higher BMI than low SES girls. Across the measurement periods, BMI and weight somewhat converged between the high and low SES girls. In the discussion these differences reflecting social sex distinctions are addressed.

SummaryIt is well known that height and weight are interrelated, and that both are related to socioeconomic variables. The objective of this study was to assess the effect of socioeconomic variables on the heights and weights of different groups of people, formed according to different levels of heights and weights, and to see whether there are sex differences in the variations in heights and weights. Data for adults aged 15–49 years were taken from the India National Family Health Survey-3 and descriptive studies and multiple linear regression analyses carried out. A clear positive association was found for height and BMI with economic level (except for overweight females in the case of BMI). In the case of BMI, it is age that seems to be the most influential factor. Surprisingly, the observed changes in height and BMI are not as expected for short and tall or underweight and overweight people; these sometimes behave in the opposite directions to that of normal height and weight people. The basic assumption of multivariate normality is not valid due to changing relations at different height and BMI levels.

Given the broad reach of anthropology as the science of humankind, there are times when the subject fragments into specialisms and times when there is rapprochement. Rather than just seeing them as reactions to each other, it is perhaps better to say that both tendencies co-exist and that it is very much a matter of perspective as to which is dominant at any moment. The perspective adopted by the contributors to this volume is that some anthropologists have, over the last decade or so, been paying considerable attention to developments in the study of social and biological evolution and of material culture, and that this has brought social, material cultural and biological anthropologists closer to each other and closer to allied disciplines such as archaeology and psychology. A more eclectic anthropology once characteristic of an earlier age is thus re-emerging. The new holism does not result from the merging of sharply distinguished disciplines but from among anthropologists themselves who see social organization as fundamentally a problem of human ecology, and, from that, of material and mental creativity, human biology, and the co-evolution of society and culture. It is part of a wider interest beyond anthropology in the origins and rationale of human activities, claims and beliefs, and draws on inferential or speculative reasoning as well as 'hard' evidence. The book argues that, while usefully borrowing from other subjects, all such reasoning must be grounded in prolonged, intensive and linguistically-informed fieldwork and comparison

Den seneste stigning i beregningsbaserede metoder inden for samfundsvidenskab har åbnet nye muligheder for at udforske kvalitative spørgsmål gennem analyse af store mængder tekst. Denne artikel anvender et blandet metode design, der inkorporerer maskinaflæsning, netværksanalyse, semantisk analyse og kvalitativ analyse af 414 højt citerede publikationer om obesogene miljøer mellem 2001 og 2015. Metoden producerer et udførligt netværkskort med fem forskellige forestillinger om miljø, hvoraf alle for tiden er aktive inden for fedmeforskning. De fem forestillinger er institutionelle, byggede, mad, familie og kropsmiljøer. Netværkskortet foreslås som et navigationsværktøj både for politiske aktører, der ønsker at koordinere indsatsen mellem en række interessenter og for forskere, der ønsker at forstå deres egne forsknings- og forskningsplaner i lyset af forskellige positioner på området. Den afsluttende del af artiklen undersøger, hvordan netværkskortet også kan indlede et bredere sæt refleksioner om konfiguration, differentiering og sammenhæng indenfor feltet fedmeforskning. ; The recent rise of computation‐based methods in social science has opened new opportunities for exploring qualitative questions through analysis of large amounts of text. This article uses a mixed‐methods design that incorporates machine reading, network analysis, semantic analysis, and qualitative analysis of 414 highly cited publications on obesogenic environments between 2001 and 2015. The method produces an elaborate network map exhibiting five distinct notions of environment, all of which are currently active in the field of obesity research. The five notions are institutional, built, food, family, and bodily environments. The network map is proposed as a navigational tool both for policy actors who wish to coordinate efforts between a variety of stakeholders and for researchers who wish to understand their own research and research plans in light of different positions in the field. The final part of the article explores how the network ...
