  1. Frequency of geophagy will be positively associated with pregnancy (110).Young, Sera L. - Why on earth?: Evaluating hypotheses about the physiological functions of hu..., 2011 - 2 Variables

    The author tests various hypotheses regarding cross-cultural occurrence of geophagy, the eating of earth. Nearly 500 years of references to geophagy were compiled into the Database on Human Geophagy, which was then used to examine biological justifications for this little-understood behavior.

  5. Geophagy during pregnancy will be most common in populations that do not practice dairying or do not consume dairy products (534).Wiley, Andrea S. - Geophagy in pregnancy: a test of a hypothesis, 1998 - 2 Variables

    Geophagy during pregnancy has been proposed to fulfill a number of adaptive functions, including relieving gastrointestinal distress, detoxification of the secondary compounds found in plant foods, and providing a supplementary source of minerals such as calcium. Using a sample of 60 African populations, the authors investigate geophagy during pregnancy in a cross-cultural perspective, emphasizing variation between dairying and non-dairying populations.

  7. Food shortage and mother-child sleeping arrangements are directly related to men's heterosexual fear (42).Kitahara, Michio - Men's hetersexual fear due to reciprocal inhibition, 1981 - 3 Variables

    This article presents a reanalysis of a study by Ember (1978) examining the predictors of men's heterosexual fear. The author finds that Ember's model is not upheld and presents a new model of men's heterosexual fear using path analysis. Results suggest that mother-child sleeping arrangements and food shortage are directly related to men's heterosexual fear.

  8. Increased frequency of famine will be associated with increased subsistence diversity.Ember, Carol R. - Resource stress and subsistence diversification across societies, 2020 - 3 Variables

    Using a cross-cultural sample of 91 societies, this paper draws on ecological theory to test if unpredictable environments will favor subsistence diversification. The general hypothesis is that societies with high climate unpredictability and resource stress would exhibit more subsistence diversity than societies in more stable climates. The authors examined four environmental and resource stress variables while controlling for temperature variance, subsistence activity, and phylogeny. Support was found for 2 of the 4 variables--chronic scarcity and environmental instability. In the discussion they suggest that more commonly observed events (e.g. annual hunger and climate unpredictability) may give people more motivation to change subsistence than rarer events (e.g. natural hazards and famine).

  9. There will be a correlation between dry climates and resource stress.Ember, Carol R. - Climate Variability, Drought, and the Belief that High Gods Are Associated w..., 2021 - 6 Variables

    The authors of this study explore the relationship between climate variability and beliefs that high gods are associated with the weather. As predicted, they find significant correlations between these beliefs and dry climates. They then evaluate how these findings contribute to their previous understanding of resource stress and its association to beliefs in high gods.

  10. Geophagy is more common in tropical environments.Young, Sera L. - Medicine beneath your feet: a biocultural examination of the risks and benef..., 2019 - 2 Variables

    Researchers examine the body of literature on the practice of geophagy(the consumption of earth), shining a light on the harms, benefits, and proposed reasoning behind the practice cross-sectionally. In addition to this review of the literature, gaps in the literature and suggestions for future research are discussed.
