Data from: Flexibility of fetal tolerance: Immune function during pregnancy varies between ecologically distinct populations

Carmen Hové, Benjamin Trumble, Amy Anderson, Jonathan Stieglitz, Hillard Kaplan, Michael Gurven & Aaron Blackwell
Background and objectives: Among placental mammals, females undergo immunological shifts during pregnancy to accommodate the fetus (i.e. fetal tolerance). Fetal tolerance has primarily been characterized within post-industrial populations experiencing evolutionarily novel conditions (e.g. reduced pathogen exposure), which may shape maternal response to fetal antigens. This study investigates how ecological conditions affect maternal immune status during pregnancy by comparing the direction and magnitude of immunological changes associated with each trimester among the Tsimane (a subsistence population...

Data from: Mother's social status is associated with child health in a horticulturalist population

High social status is often associated with greater mating opportunities and fertility for men, but do women also obtain fitness benefits of high status? Greater resource access and child survivorship may be principal pathways through which social status increases women’s fitness. Here we examine whether peer-rankings of women’s social status (indicated by political influence, project leadership and respect) positively covaries with child nutritional status and health in a community of Amazonian horticulturalists. We find that...

Tsimane physiological dysregulation data

Thomas Kraft, Jonathan Stieglitz, Benjamin Trumble, Angela Garcia, Hillard Kaplan & Michael Gurven
Humans have the longest post-reproductive lifespans and lowest rates of actuarial aging among primates. Understanding the links between slow actuarial aging and physiological change is critical for improving the human “healthspan”. Physiological dysregulation may be a key feature of aging in industrialized populations with high burdens of chronic “diseases of civilization”, but little is known about age trajectories of physiological condition in subsistence populations with limited access to public health infrastructure. To better characterize human...
