Variation in diurnal cortisol patterns among the Indigenous Shuar of Amazonian Ecuador Am. J. Hum. Biol. (IF 2.9) Pub Date : 2024-03-22 Melissa A. Liebert, Samuel S. Urlacher, Felicia C. Madimenos, Theresa E. Gildner, Tara J. Cepon‐Robins, Christopher J. Harrington, Richard G. Bribiescas, Lawrence S. Sugiyama, J. Josh Snodgrass
ObjectivesThe hypothalamic–pituitary–adrenal (HPA) axis and its primary end product, the glucocorticoid cortisol, are major components of the evolved human stress response. However, most studies have examined these systems among populations in high‐income settings, which differ from the high pathogen and limited resource contexts in which the HPA axis functioned for most of human evolution.MethodsWe

Hyperandrogenism associated with polycystic ovary syndrome may have a protective effect against fracture risk in female athletes: A pilot study Am. J. Hum. Biol. (IF 2.9) Pub Date : 2024-03-16 Courtney Manthey, Tara Cepon‐Robins, Anna Warrener
ObjectivesPolycystic ovary syndrome (PCOS), characterized by polycystic ovaries, anovulation, and hyperandrogenism, is believed to be an evolutionary mismatch disease. Past research has examined PCOS as a uniform disease, despite variation in phenotypes across diagnostic categories, but establishing an evolutionary mismatch requires a focus on individual traits. We suggest PCOS hyperandrogenism may

Maternal and infant predictors of proinflammatory milk immune activity in Kilimanjaro, Tanzania Am. J. Hum. Biol. (IF 2.9) Pub Date : 2024-03-02 Katherine Wander, Masako Fujita, Siobhán Mattison, Megan Gauck, Margaret Duris, Ireen Kiwelu, Blandina T. Mmbaga
ObjectivesThe immune system of milk (ISOM) creates a mother–infant immune axis that plays an important role in protecting infants against infectious disease (ID). Tradeoffs in the immune system suggest the potential for both protection and harm, so we conceive of two dimensions via which the ISOM impacts infants: promotion of protective activity and control of activity directed at benign targets.

Intimate partner violence, depression, and chronic low-grade inflammation among middle-aged women in Cebu, Philippines Am. J. Hum. Biol. (IF 2.9) Pub Date : 2024-02-14 Jacob E. Aronoff, Stephanie M. Koning, Linda S. Adair, Nanette R. Lee, Delia B. Carba, Christopher W. Kuzawa, Thomas W. McDade
Recent discussions in human biology have highlighted how local ecological contexts shape the relationship between social stressors and health across populations. Chronic low-grade inflammation has been proposed as a pathway linking social stressors to health, with evidence concentrated in high-income Western contexts. However, it remains unclear whether this is an important pathway in populations where

Medieval monastic health: Variation in skeletal signs of inflammation and developmental stress between religious orders in London Am. J. Hum. Biol. (IF 2.9) Pub Date : 2024-02-13 Sharon N. DeWitte
Previous bioarchaeological analyses of medieval monastic and nonmonastic cemeteries in London revealed evidence of lower risks of mortality, and thus better health, in the monastic settings. However, comparison of the two monastic communities, Bermondsey Abbey and Merton Priory, which adhered to different religious ideals, suggested lower risks of mortality in the former. This study examines patterns

The associations between digit ratio (2D:4D and right – left 2D:4D), maximal oxygen consumption and ventilatory thresholds in professional male football players Am. J. Hum. Biol. (IF 2.9) Pub Date : 2024-02-02 Koulla Parpa, John T. Manning, Magdalena Kobus, Laura Mason, Marcos Michaelides
Digit ratio (2D:4D: the relative length of the 2nd and 4th digit) is thought to be a negative correlate of prenatal testosterone. The 2D:4D is related to oxygen metabolism, but the precise nature of this relationship is unclear. The purpose of the present study was to consider associations between digit ratios (right 2D:4D, left 2D:4D, right–left 2D:4D [Dr-l]) and VO2max and ventilatory thresholds
