“…Standard age- and sex-based reference values for clinical practice were used to determine thresholds for anemia and elevated CRP (acute inflammation) classification (Mayo Clinic 2015). Finally, parasitic infection was determined based on assessment of fecal samples from a sub-sample of 115 study participants (in 2003 and 2007) (Tanner et al 2009; Tanner et al 2013). Children were classified as infected vs. not by presence or absence of any hookworm in fecal samples.…”

Objectives We investigated the relationship between early childhood malnutrition-related measures and subsequent enamel defects in the permanent dentition. Materials and Methods This cohort study included 349 Amerindian adolescents (10–17 years, 52% male) from the Bolivian Amazon. Exposures included: stunted growth (height-for-age z-scores), underweight (weight-for-age z-scores), anemia (hemoglobin), acute inflammation (C-reactive protein) and parasitic infection (hookworm). We measured the occurrence (no/yes) and extent (<1/3, 1/3–2/3, >2/3) of enamel defects. We estimated associations between childhood exposures and enamel defect measures using log-binomial and multinomial logistic regression. Results The prevalence of an enamel defect characterized by a cobblestone-like depressed surface of deficient enamel thickness on the labial surface of the central maxillary incisors was 92.3%. During childhood (1–4 years), participants had a high prevalence of stunted growth (75.2%), anemia (56.9%), acute inflammation (39.1%), and hookworm infection (49.6%). We observed associations between childhood height-for-age (OR=0.65; p=0.028 for >2/3 extent vs. no EH) and gastrointestinal hookworm infection (OR=3.43; p=0.035 >2/3 extent vs. no defects or <1/3 extent) with enamel defects. Discussion The study describes a possibly novel form of enamel hypoplasia and provides evidence for associations of malnutrition-related measures in early childhood, including stunted growth and parasitic helminth infection, with the observed enamel defects.

“…The TAPS panel is ideally suited to examine the existence and magnitude of catch-up growth and the extent to which early environmental influences may shape variation in body size and composition later in life (e.g., Godoy et al 2010a; Tanner et al 2014). In addition, these data also allow for the evaluation of how particular dimensions of lifestyle change (e.g., diet, engagement in wage labor and subsistence activities, access to material wealth; level of traditional knowledge) play a role in shaping both early patterns of development and adult health outcomes (e.g., McDade et al, 2007; Reyes-Garcia et al, 2009; Rosinger et al, 2013; Tanner et al, 2013). …”

This brief communication contains a description of the 2002-2010 annual panel collected by the Tsimane’ Amazonian Panel Study team. The study took place among the Tsimane’, a native Amazonian society of forager-horticulturalists. The team tracked a wide range of socio-economic and anthropometric variables from all residents (633 adults ≥16 years; 820 children) in 13 villages along the Maniqui River, department of Beni. The panel is ideally suited to examine how market exposure and modernization affect the well-being of a highly autarkic population and to examine human growth in a non-Western rural setting.

“…Tsimane' children and adults have a 56-80 % prevalence of parasitic helminthic infections (10,11) . Infectious diseases, including GI infection, historically have accounted for more than 50 % of all deaths (45) .…”

“…The paper focuses on Tsimane' because they lack access to clean water, yet are highly active and live in a hot, humid environment, creating high water needs. Additionally, previous research has documented high prevalences of water-related diarrhoeal diseases and parasitic infection (10,11) . …”

Objective: Water is an essential nutrient overlooked in many cross-cultural studies of human nutrition. The present article describes dietary water intake patterns among forager-horticulturalist adults in lowland Bolivia, compares daily intake with international references and examines if variation in how people acquire water relates to gastrointestinal illness. Design: Cross-sectional observational study used survey, anthropometric and qualitative methods with Tsimane' adults selected by age and sex stratification sampling in one community. Setting: Research occurred in one Tsimane' village in the Beni department, Bolivia with limited access to clean water. The 24 h diet and health recalls were conducted in July-August 2012 and qualitative interviews/ethnographic observation in September-October 2013. Subjects: Forty-five Tsimane' household heads (49 % men) took part in the first data collection and twenty-two Tsimane' (55 % men) were included in the followup interviews. Results: Men and women reported consuming 4·9 litres and 4·4 litres of water daily from all dietary sources, respectively. On average, water from foods represented 50 % of total water intake. Thirteen per cent of participants reported symptoms of gastrointestinal illness. In a logistic regression model adjusted for age, BMI, sex and raw water consumed, each percentage increase in water obtained from foods was associated with a reduced risk of gastrointestinal illness (OR = 0·92; 95 % CI 0·85, 0·99). Conclusions: Both total water intake and percentage of water from foods were higher than averages in industrialized countries. These findings suggest that people without access to clean water may rely on water-rich foods as a dietary adaptation to reduce pathogen exposures. Keywords Hydration strategiesWater intake Gastrointestinal illness Tsimane' AmazoniaAccess to improved water sources, such as hand-pumps or other technology designed to protect against fecal contamination, continues to be a critical public health problem among rural indigenous populations in lowincome countries (1) . To complement this need, the present study examines how individuals use local environmental resources to acquire water and the resulting health consequences (2) . Dietary flexibility serves as an adaptation to environmental constraints and relates to variation in nutrition, health and disease patterns (3,4) . Human populations have long used behaviours and food processing techniques as culturally integrated buffers that reduce toxicity and increase the digestibility and nutrients of food, such as the 10 d processing of bitter manioc (5) , corn alkali processing to reduce niacin deficiency (6) and fire and cooking (7) . Likewise, researchers hypothesize that people have historically used dietary strategies to flexibly meet their water needs, such as eating fruits when water is unavailable or using beer, gruel or cider fermentation to render dirty water drinkable and potentially medicinal (8,9) . In the present paper we describe hydration strategies, or a perso...

Health and adult productivity: The relation between adult nutrition, helminths, and agricultural, hunting, and fishing yields in the Bolivian Amazon

Abstract: These findings suggest that the effects of adult infection and nutritional stress may be less clearly identified outside of the context of wage labor. Further research linking adult physical activity levels and metabolic rates to productivity in diverse contexts is needed.
