“…The source of data for the ''new values'' also seems justified from the paleontological, archaeological, and contemporary ethnographic-biological forager record. Human forager groups show evidence of nutritional deprivation in terms of low height-and weight-for-age and low body fat stores (De Souza, 2006;Jenike, 2001). Contemporary foragers have relatively high infant mortality, which lowers expectation of life at birth (De Souza, 2006;Pennington, 2001).…”

Contemporary foragers have relatively high infant mortality, which lowers expectation of life at birth (De Souza, 2006;Pennington, 2001). High levels of infant mortality are also widely used as a measure of adversity in overall health (Bogin et al, 2007).…”

The grandmother hypothesis (GH) of Hawkes et al. ([1998]: Proc Natl Acad Sci USA 95: 1336-1339) finds that selection for lower adult mortality and greater longevity allow for the evolution of prolonged growth in human beings. In contrast, other researchers propose that the evolution of the human childhood and adolescent stages of life history prolonged the growth period and allowed for greater biological resilience and longevity compared with apes. In this article, the GH model is reanalyzed using new values for some of its key variables. The original GH set the age at human feeding independence at 2.8 years of age (weaning) and used demographic data from living foragers to estimate average adult lifespan after first birth at 32.9 years. The reanalysis of the GH uses age 7.0 years (end of the childhood stage) as the minimum for human feeding independence and uses data from healthier populations, rather than foragers, to derive an estimate of 48.9 years for average adult life span. Doing so finds that selection operated to first shorten the infancy stage (wean early compared with apes), then prolong the growth period, and finally result in greater longevity. The reanalysis provides a test of the reserve capacity hypothesis as part of a multilevel model of human life history evolution.

“…Despite increasing food ranges, new food products and consumption of environmental resources in conventional and organic food production, many people remain hungry and malnourished worldwide (Blomhoff 1991;ACC/SNC 1992;Garnier et al 2003;Simopoulos and Gopalan 2003;Čolić-Barić et al 2004;Herdt 2004;Sanghvi 2004;De Souza 2006). This occurs most commonly in underdeveloped regions, but can occur in developed regions due to economic oscillations.…”

“…Frank malnutrition or the threat of self-imposed malnutrition (whether or not it is actually realized) are traumatic experiences that threaten the well-being and physical status at any stage of development. It stands to reason that nutritional disturbance or deficit, defining features of eating disorders, during particularly vulnerable developmental periods can result in excessive and potentially permanent physical and psychological consequences (De Souza, 2006). As adequate nutrition is the necessary substrate for all biological growth, the fact that the malnutrition of eating disorders principally begins in adolescence and can also onset prior to adolescence necessitates flexibility in diagnostic boundaries based on developmental stage.…”

Childhood and adolescence are critical periods of neural development and physical growth. The malnutrition and related medical complications resulting from eating disorders such as anorexia nervosa (AN), bulimia nervosa (BN) and eating disorder not otherwise specified may have more severe and potentially more protracted consequences during youth than during other age periods. The consensus opinion of an international workgroup of experts on the diagnosis and treatment of child and adolescent eating disorders is that (a) lower and more developmentally sensitive thresholds of symptom severity (e.g. lower frequency of purging behaviours, significant deviations from growth curves as indicators of clinical severity) be used as diagnostic boundaries for children and adolescents, (b) behavioural indicators of psychological features of eating disorders be considered even in the absence of direct self-report of such symptoms and (c) multiple informants (e.g. parents) be used to ascertain symptom profiles. Collectively, these recommendations will permit earlier identification and intervention to prevent the exacerbation of eating disorder symptoms.

Body size and growth: The significance of chronic malnutrition among the Casiguran Agta

Abstract: Demographic indicators of poor health-related quality of life are consistent with slowed patterns of growth observed, stressing the importance of environmental pressure in maintaining the short stature of the Agta population.
