Measuring food insecurity
Food Insecurity, Nutritional Inequality, and Maternal-Child Health
Food insecurity, a significant contributor to nutritional inequality, disproportionately affects women and children in low- and middle-income countries. The magnitude of the problem has inspired research on its impacts on health, especially on nutritional status and, more recently, mental well-being. Current research is dominated by surveillance-type studies that emphasize access, one of food security's four dimensions. Findings are inconclusive …
Variation in dietary intake and body fatness by socioeconomic status among women in the context of Costa Rican nutrition transitions
The Nutrition Transition model posits that vegetable oils, animal source foods (ASFs) and caloric sweeteners contribute to increases in adiposity and hence body mass index. Body mass index (BMI) is increasing more rapidly among Latin American populations of low versus high socioeconomic status (SES). The objectives of this study among Costa Rican women were to: (1) compare indicators of adiposity and dietary intake by SES and (2) evaluate the rel…
Shift in body fat distribution from lower body to upper body among urban Colombian women, 1988–1989 to 2007–2008
Objective: Body fat distribution may be a stronger predictor of metabolic risk than BMI. Yet, few studies have investigated secular changes in body fat distribution in middle-income countries or how those changes vary by socioeconomic status (SES). This study evaluated changes in body fat distribution by SES in Colombia, a middle-income country where BMI is increasing rapidly. Design: We applied factor analysis to previously published data to ass…

Reflections on nutrition in biological anthropology
Some 50 years ago, and befittingly at an AAPA dinner, Stanley Garn delivered the Presidential Address, which he titled Nutrition in Physical Anthropology. In his address, Garn predicted, “a concern with nutrition in its broadest sense, including the physical form of the dietary and the energy balance will occupy us more rather than less in the years to come, as we channel our interests to ascertain the directions of evolutionary and physiological…

Reliance Upon a Toxic Staple Crop
In Amazonia most indigenous horticulturists prefer to cultivate the more toxic forms of manioc as a staple crop, despite the increased processing required to render them safe for consumption. This phenomenon has long intrigued anthropologists. In this chapter we describe the agricultural practices of the Tukanoan Indians in the North-west Amazon and explore their reliance on toxic varieties of manioc from agronomic, ecological, organoleptic, and …
Using the protein leverage hypothesis to understand socioeconomic variation in obesity
Consistent with the PLH, absolute protein intake was similar across SES groups. The relationship between the proportion of protein in the diet and total energy intake should be studied further in the context of real world conditions that may influence protein leverage
No change in energy efficiency in lactation
We found no support for the idea that lactating women undergo an increase in energy efficiency to support the energy costs of lactation

Perceptions of food availability and self-reported dietary intake in urban Costa Rican women
Background: In Latin America, obesity is rising among women of low socioeconomic status (SES). Food availability and dietary intake are thought to be important contributors. In Costa Rica, few studies have investigated food availability, dietary intake, or how they vary by SES. Objectives: The purpose of this study in San José, Costa Rica was to (1) evaluate women’s perceptions of food availability and, (2) describe dietary intake in women from l…
Percepciones sobre disponibilidad de alimentos y autorreporte de ingesta alimentaria en mujeres urbanas costarricenses
Antecedentes: Se considera que la disponibilidad y consumo de alimentos han contribuido al aumento de obesidad entre las mujeres de bajo nivel socioeconómico (NSE) en Latinoamérica. En Costa Rica, pocos estudios han investigado cómo la disponibilidad y consumo varían según NSE. Objetivos: Los objetivos de este estudio en San José, Costa Rica, son (1) evaluar percepciones sobre la disponibilidad de alimentos y (2) describir el consumo de alimentos…

Stable isotopes (carbon, nitrogen, sulfur), diet, and anthropometry in urban Colombian women
OBJECTIVES: We conducted stable isotope and dietary analyses of women from higher and lower socioeconomic status (SES) groups in Cali, Colombia. The objectives were to test between-group differences in stable isotope, dietary, and anthropometric characteristics, and to evaluate relationships between diet and stable isotope values. METHODS: Hair samples from 38 women (mean age 33.4) from higher and lower SES groups were analyzed for δ(13) C, δ(15)…
Local trends in diet in urban C olombia, 1990–1995 to 2008
OBJECTIVES: To quantify changes in the diets of low-income women in Cali, Colombia between 1990-1995 and 2008, a period of increases in body size, and to situate these changes within national-level trends in food availability, as well as to compare these changes with those expected in countries undergoing a nutrition transition. METHODS: Individual dietary intake was assessed via 24-hour recalls in both 1990-1995 (n = 85) and 2008 (n = 88). Dieta…
Exploring the multidimensionality of stature variation in the past through comparisons of archaeological and living populations
Adult stature variation is commonly attributed to differential stress‐levels during development. However, due to selective mortality and heterogeneous frailty, a population's tall stature may be more indicative of high selective pressures than of positive life conditions. This article examines stature in a biocultural context and draws parallels between bioarchaeological and living populations to explore the multidimensionality of stature variati…
Socioeconomic status, stature, and obesity in women
OBJECTIVES: Ongoing social and economic changes in developing countries are associated with increases in body size, and most notably increases in the prevalence of obesity. The social patterning of these changes in terms of socioeconomic status (SES) is not well documented. The aim of this study was to assess the changes in stature, body mass index (BMI) and fatness in adult women in urban Cali, Colombia between 1988-1989 and 2007-2008. METHODS: …

Energy expenditure among farmers in developing countries
The trend toward overweight and obesity in developing countries is often assumed to be due, in part, to reductions in energy expenditure associated with the transition from agrarian to urban lifestyles. In this article we first review the published studies on energy expenditure in farming populations living in developing countries, populations generally assumed to have high levels of energy expenditure. To facilitate comparison we express energy …

Diet, energy expenditure, and body composition of lactating Ribeirinha women in the brazilian amazon
Lactation is the most energetically demanding part of human reproduction; yet, compared with pregnancy, we know little about the strategies women in different settings employ to cope with these increased energy demands. This paper takes a biocultural approach and reports longitudinal data on the anthropometry, dietary intakes and energy expenditure of a sample of 23 rural, lactating Ribeirinha women living in subsistence‐based communities in the …
Insects as Food
In this article I examine the use of insects as food by Tukanoan Indians in the Northwest Amazon and discuss both the characteristics of the species exploited and their significance in the diet. Data on insect collection were obtained from harvest records and participant-observation. Dietary intake was determined from weighed food intake records. The insects collected belonged to over 20 species. The most important in the diet were those which fo…
Fish and Farinha
In order to better understand food consumption among indigenous peasant (the so-called “Caboclos”) communities in Amazonia, this article describes and analyzes household and individual food consumption in the communities of Aracampina and São Benedito, located on ltuqui Island on the lower courses of the Amazon river, in the municipio (county) of Santarém, State of Pará, Brazil. ltuqui Island's landscape is dominated by savannas, meadows, seconda…

The time and energy expenditure of indigenous women horticulturalists in the Northwest Amazon
The energy cost of subsistence activities and the daily time and energy budgets of Tatuyo women were assessed as part of a village energy flow study. The Tatuyo are swidden horticulturalists relying on bitter manioc ( Manihot esculenta ) as a staple crop. Except for the actual felling of new gardens, women are responsible for most of the horticultural work and food preparation. Time budgets were assessed using 24‐hour activity diaries. Rates of e…

Nutrition, Activity, and Health in Children
This chapter reviews current understanding of the associations between physical activity and nutrition in children 1 to 10 years of age. In general, both undernutrition and overnutrition are accompanied by lower levels of physical activity than in controls. In children of normal nutritional status, an association between physical activity and body composition has been difficult to demonstrate. It is clear that levels of physical activity in child…
Coca Chewing and High-Altitude Stress
Because the main present-day centres of coca chewing are in the high altiplano regions of Peru and Bolivia, it has been widely assumed that the habit evolved primarily as a response to the stresses of life at high altitudes. When archaeological, ethnohistorical, and botanical sources of evidence are considered, a different emphasis emerges. Before the European conquest, coca was chewed everywhere from Nicaragua to Chile and at all altitudes. This…

Ethnobotanical Evidence for Cultivar Selection among the Tukanoans
Manioc (Manihot esculenta Crantz) is a cyanidecontaining root crop that is cultivated by many indigenous groups in Amazonia. Although the Tukanoans of the Northwest Amazon grow low cyanogenic-potential (CNP) manioc, high-CNP manioc, requiring detoxification prior to consumption, provides over 80 percent of the calories they consume. The purpose of this paper is to determine which characteristics of manioc are most important to the Tukanoans in th…

Skin temperatures at the nape in infants at high altitude
Skin temperatures were measured on three Quechua Indian infants resident at 4,000 meters above sea level in Peru. Nape temperatures were warmer than other skin sites, suggesting that the brown adipose tissue associated with non‐shivering thermogenesis is metabolically active despite the reduced oxygen availability at high altitude. The question of the role of non‐shivering thermogenesis in infant thermoregulation under the covariant stresses of h…

Diet and nutritional status of Ameridians
This paper reviews and evaluates the available data on diet and nutritional status of Amerindians living in the tropical forests of Amazonia. The diets of most Amerindians are based on cassava and plantains/bananas, with high quality protein coming from fish, game and invertebrates. The composition of Amerindian diets is known for only a few groups. In these groups the dietary intake of households and adults appears to be adequate in energy and p…

Nutritional ecology in the tropical rain forests of Amazonia
Available data on diet and nutritional status of Amerindians living in the tropical rain forests of Amazonia are reviewed and evaluated. The diets of most Amerindians are based on cassava and plantains/bananas, with high‐quality protein coming from fish, game, and invertebrates. Although tropical rain forests are rich in plant species, wild plants do not appear to be very important in the diet. Their use, however, has not received much attention …

Anthropometry and secular changes in stature of urban Colombian women of differing socioeconomic status
Anthropometric dimensions were taken on 1,572 women, 18–44 years of age, from Cali, Colombia, from three different socioeconomic (SEC) groups: low (LEC), mid‐low (MLEC), and upper (UEC). LEC and MLEC women were significantly shorter and had higher body mass indices (BMIs) than UEC women, and a significantly larger number had BMIs over 27.3 kg/m 2 . There were no significant differences between SEC groups for skinfolds on the arm, but skinfolds on…

Energy expenditures of urban Colombian girls and women
Anthropometry, basal metabolic rate (BMR), and resting energy expenditure (RMR) measured by indirect calorimetry and total daily energy expenditure (TDEE) by the minute-by-minute heart rate (HR) method have been studied in 52 school-aged girls 6-16 years and 46 nonpregnant, nonlactating women 19-43 years of age. BMR, RMR, and TDEE increased with age in children, reaching approximate adult values by 15 years. TDEE averaged 9.29 ± 2.32 MJ/d in wome…
Comparative study of flex heart rate in colombian children and in pregnant, lactating, and non‐pregnant, nonlactating women
The heart rate (HR) value employed to separate resting and active portions of the calibration curves used to estimate energy expenditure (EE) from minute-by-minute HR recordings is called the flex-HR. The present study has characterized it, the resting HR and the average daily HR during the awake portion of the day (12–14 h) by comparing age, gender and nutritional status effects related to measured maximum oxygen consumption (V̇ max; ml/min/kg b…
