Navigating Change
This Pilagá community is experiencing a dietary transition toward westernized foods, driven by biosociocultural factors that mirror broader shifts in local food systems and consumption patterns
Longitudinal analysis of cortisol changes during pubertal development in indigenous Qom girls
Pubertal research has primarily focused on hypothalamic–pituitary–gonadal axis (HPG) regulation of puberty, though the hypothalamic–pituitary–adrenal axis (HPA) is increasingly considered critical. Heightened HPA function proxied by increasing cortisol levels may play a role in accelerated pubertal timing. However, the extent to which cortisol varies across ages and its relation to pubertal changes in linear growth are less well substantiated. We…
Infrastructural violence and resistance in Namqom
Infrastructure connects – and disconnects – people and communities. In this paper, we analyze how the Qom (an Indigenous population in the Gran Chaco region of Argentina) navigate marginalization enacted through infrastructure in Formosa, Argentina. Drawing upon two seasons of fieldwork that involved surveys, semi-structured interviews, and participant observation, we focus on experiences of Qom people in the peri-urban village of Namqom. We exte…
Perceptions of the healthiest body in a market‐integrating indigenous population in Argentina
Objectives Market integration seems to induce gender‐specific generational change in health‐related perceptions of body size. We predicted that among the Qom of Argentina, younger women would perceive comparatively thinner bodies as healthiest, demonstrating thin‐idealizing body norms, and older women would retain culturally rooted perceptions of heavier bodies as healthiest. As traditional and globalized body size ideals are different for men, w…
Birth mode and infectious morbidity risks in Qom children of Argentina
OBJECTIVES: Cesarean delivery may increase childhood infectious morbidity risks via altered birth exposures and subsequent immune, microbial, and epigenetic development. Many Latin American indigenous populations experience dual burdens of infectious and chronic diseases, and are particularly vulnerable to rising rates of cesarean delivery and associated adverse outcomes. The Qom/Toba are an indigenous population in Argentina experiencing rapid l…
Growth patterns among indigenous Qom children of the Argentine Gran Chaco
OBJECTIVES: This study describes and compares the growth strategies of rural (Western) and peri-urban (Eastern) Qom indigenous children from Argentina. METHODS: Height and weight were cross-sectionally assessed in Western (n = 263) and Eastern Qom (n = 512) individuals aged 0-18.9 years. Height-for-age (HAZ), weight-for-age (WAZ), and BMI-for-age (BMIZ) z-scores were calculated with an LMS software. Results were organized into four age categories…
Impact of Universal Health Coverage on Child Growth and Nutrition in Argentina
Objectives. To estimate trends of undernutrition (stunting and underweight) among children younger than 5 years covered by the universal health coverage programs Plan Nacer and Programa Sumar. Methods. From 2005 to 2013, Plan Nacer and Programa Sumar collected high-quality information on birth and visit dates, age (in days), gender, weight (in kg), and height (in cm) for 1.4 million children in 6386 health centers (13 million records) with broad …
Health of Indigenous Peoples
Indigenous populations worldwide are experiencing social, cultural, demographic, nutritional, and psychoemotional changes that have a profound impact on health. Regardless of their geographical location or sociopolitical situation, health indicators are always poorer for indigenous populations than for nonindigenous ones. The determinants of this gap are multiple and interactive, and their analysis requires a biocultural framework. Indigenous pop…

Coca-Colonization and Hybridization of Diets among the Tz'utujil Maya
Biomedical health professionals express increasing concern that rising consumption of soft drinks and processed foods in Mayan and Latin American eating patterns may lead to detrimental nutritional and health consequences. Scholars debate whether the pervading presence of Coca-Cola and Pepsi in developing countries represents "Coca-Colonization," synonymous with cultural imperialism, or cultural hybridization. Using mixed qualitative and quantita…
Evolutionary perspectives on human diet and nutrition
Body mass index, socio-economic status and socio-behavioral practices among Tz’utujil Maya women
Abstracts of AAPA poster and podium presentations
Originally hunter-gatherers, the Toba of northern Argentina now exhibit a range of subsistence practices. Their environment, diet, and physical activity patterns are considerably seasonal. With the purpose of examining seasonal and age-related changes in testosterone (T) levels, we collected morning and evening saliva samples and anthropometric measures from 153 men ages 12 to 83, in each of three distinct seasons. Data from a subset of n=48 men …
Nutritional status and socioeconomic change among Toba and Wichí populations of the Argentinean Chaco
The Biology of Paternal Care in Human and Nonhuman Primates
Among primates, intense paternal care is manifested in only a few distantly related species, including humans. Thus, neither purely phylogenetic nor socioecological hypotheses can explain its presence or the variability in the expression of paternal behaviors. Traditional theoretical models for the evolution of paternal care can now be reexamined, focusing on male-female interactions as a possible key to understanding parental strategies. At a pr…
Taking the Lab to the Field
The incorporation of biological measures in social science research allows for the development of robust models, with greater explanatory power. By analyzing the underlying proximate causes of fertility and mortality, biodemographers have been able to model demographic patterns more accurately. Recent technological advances are making possible the analysis of biological samples collected using minimally invasive methods. Methods and techniques ar…
Impact of breastfeeding on anthropometric changes in peri‐urban Toba women (Argentina)
We present an analysis of the effect of lactation on average maternal anthropometric and body composition measures in a population of Toba women in Formosa, Argentina. This indigenous population is undergoing a continuing transition from a seminomadic hunter–gatherer lifestyle to a sedentary, peri‐urban one. Using a mixed‐longitudinal design, we measured monthly maternal body mass index (BMI), body fat percentage, and triceps and subscapular skin…
