  1. "In societies where infants' heads/limbs were repeatedly molded or stretched, where ears, noses or lips were pierced, where they were circumcised, vaccinated, innoculated or scarred with tribal marks, mean adult stature was over two inches greater" (1018)Landauer, Thomas K. - Infantile stimulation and adult stature of human males, 1964 - 4 Variables

    In previous studies, researchers have observed an increased growth rate in rats that experienced stimulation during infancy. This study examines the relationship between stressful experiences during infancy and adult male stature in humans cross-culturally. Results suggest a strong positive relationship between infant stress and adult male stature.

  2. The effect of one physical stressor will not differ significantly from the effect of two or more combined stressors (360).Landauer, Thomas K. - Correlates and consequences of stress in infancy, 1981 - 2 Variables

    This study is a continuation of previous research on the relationship between stress during infancy and adult height. With a better understanding of the stressors that infants experience and their effects, the authors test whether the relationship between stress and adult height remains significant when accounting for other environmental factors that may influence adult height. Results suggest that the relationship between infant stress and adult height does remain significant. Findings also show a relationship between infant stress and age at menarche.

  3. Controlling for genetics, climate, and nutrition, infant stress will be significantly related to adult male height (361).Landauer, Thomas K. - Correlates and consequences of stress in infancy, 1981 - 5 Variables

    This study is a continuation of previous research on the relationship between stress during infancy and adult height. With a better understanding of the stressors that infants experience and their effects, the authors test whether the relationship between stress and adult height remains significant when accounting for other environmental factors that may influence adult height. Results suggest that the relationship between infant stress and adult height does remain significant. Findings also show a relationship between infant stress and age at menarche.

  4. Adult male height will be greater in societies located in high latitudes than those located in low latitudes (240).Whiting, Marjorie Grant - A Cross-Cultural Nutrition Survey of 118 Societies, Representing the Major C..., 1958 - 2 Variables

    Dietary variation has been implicated in population-level heath outcomes such as adult height and infant health. Here the author investigates these relationships in a sample of 118 nonindustrial societies, providing a comparative and quantitative assessment of nutrition and health cross-culturally.

  5. Male parental investment will be negatively associated with sexual dimorphism of stature (227).Wolfe, Linda D. - A cross-cultural investigation into the sexual dimorphism of stature, 1982 - 2 Variables

    This article examines height and sexual dimorphism of stature from a sociobiological perspective. Diet, child rearing, and marriage practices are tested as possible factors contributing to height sexual dimorphism of stature. Results provide some support for a nutritional hypotheses, but sexual selection and parental investment are not statistically significant.

  6. In societies where females have the social status to exercise mate choice, there will be lower stature sexual dimorphism (SSD), but only if there is high food security.Gleeson, Ben Thomas - Female status, food security, and stature sexual dimorphism: Testing mate ch..., 2018 - 6 Variables

    The present study examines the effect of social status on stature sexual dimorphism and whether food security acts as a mediator for this relationship. In societies where females have high social status and can exercise mate choice, there is lower stature sexual dimorphism. Food security enhances these results. Conversely, there is greater stature sexual dimorphism in societies where females have low social status and cannot exercise mate choice, especially if there is food insecurity.

  7. Adult male height will be greater in societies that increase protein for boys at puberty than those that do not (240).Whiting, Marjorie Grant - A Cross-Cultural Nutrition Survey of 118 Societies, Representing the Major C..., 1958 - 2 Variables

    Dietary variation has been implicated in population-level heath outcomes such as adult height and infant health. Here the author investigates these relationships in a sample of 118 nonindustrial societies, providing a comparative and quantitative assessment of nutrition and health cross-culturally.

  9. "The average menstrual age is younger in societies where the average height of females is greater" (223)Whiting, John W.M. - Menarcheal age and infant stress in humans, 1965 - 2 Variables

    This study examines the relationship between infant stress and early menarche. Empirical analysis suggests that stress in infancy, such as mother-infant separation and head-shaping, are associated with early menarche.
