  1. Menarcheal age was negatively related to infant cold stress and infant internal stress (227)Whiting, John W.M. - Menarcheal age and infant stress in humans, 1965 - 3 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.

  2. "The association between menarcheal age and the Gunders mother separation scores . . . [indicates] that this type of stress also leads to early menarche" (228)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.

  3. "[When] we . . . correlated menarcheal age with the Landauer-Whiting measure of infant stress . . . pain and shaping did show a positive association" (226)Whiting, John W.M. - Menarcheal age and infant stress in humans, 1965 - 3 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.

  4. 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.

  5. 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.

  6. 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.

  7. There is less phenotypic diversity of the female birth canal with greater distance from sub-Saharan Africa.Betti, Lia - Human variation in the shape of the birth canal is significant and geographi..., 2018 - 2 Variables

    The 'obstetrical dilemma' postulates that human females evolved a pelvis shape that was a compromise between the needs of bipedal locomotion and the need for a wider pelvic opening. The implication is that the female pelvis should be similar across the world. Researchers examine the size and shape of the birth canal of female individuals in the Goldman and Human Origin datasets. Contrary to the 'obstetrical dilemma,' the findings reveal that there is indeed significant geographical variation in size and shape of the female birth canal. Neutral evolutionary processes, particularly genetic drift, were suggested to be influential in female canal shape whereas the predicted effects of climate on canal diversity were only minimal.
