  • Salivary Testosterone, Age, and Adiposity Associations Among Shuar Males in Amazonian Ecuador Challenge Assumptions of “Normal” Testosterone Patterns

    Open AccessTheresa E Gildner, Melissa A Liebert et al.ARTICLEAmerican Journal of Human Biology2025

    Objectives Adult male testosterone concentrations in high income countries often decrease with age and adiposity, a pattern typically viewed as “normal.” However, testosterone is expected to be adaptively regulated within the range of resource constrained, high pathogen, natural fertility conditions across which it evolved to function. We therefore examine associations among testosterone diurnal variation, age, and adiposity among Indigenous Shua…

  • Trauma History Predicts Decoupling of C-Reactive Protein and Somatic Symptoms

    Joshua M Schrock, Robin Nusslock et al.ARTICLEPsychosomatic Medicine2023

    OBJECTIVE: Systemic inflammation can induce somatic symptoms (e.g., pain, nausea, fatigue) through neuroimmune signaling pathways. Previous research suggests that early-life adversity amplifies signaling between peripheral inflammation and the brain. We therefore hypothesized that greater lifetime trauma exposure at baseline would predict stronger associations between systemic inflammation and somatic symptoms at 2.5-year follow-up in a cohort st…

  • Low prevalence of anemia among Shuar communities of Amazonian Ecuador

    Open AccessAlicia M Delouize, Melissa A Liebert et al.ARTICLEAmerican Journal of Human Biology2022

    OBJECTIVE: Anemia is an important global health challenge. We investigate anemia prevalence among Indigenous Shuar of Ecuador to expand our understanding of population-level variation, and to test hypotheses about how anemia variation is related to age, sex, and market integration. METHODS: Hemoglobin levels were measured in a total sample of 1650 Shuar participants (ages 6 months to 86 years) from 46 communities between 2008 and 2017 to compare …

  • Soil‐transmitted helminth infection and intestinal inflammation among the Shuar of Amazonian Ecuador

    Open AccessTara J Cepon‐robin, Theresa E Gildner et al.ARTICLEAmerican Journal of Physical…2019Cited by: 6References: 73

    OBJECTIVES: Little research exists documenting levels of intestinal inflammation among indigenous populations where exposure to macroparasites, like soil-transmitted helminths (STHs), is common. Reduced STH exposure is hypothesized to contribute to increased prevalence of elevated intestinal inflammation in wealthy nations, likely due to coevolutionary histories between STHs and human immune systems that favored anti-inflammatory pathways. Here, …

  • Food insecurity partially mediates associations between social disadvantage and body composition among older adults in india

    Open AccessJoshua M Schrock, Heather H Mcclure et al.ARTICLEAmerican Journal of Human Biology2017

    OBJECTIVE: Our objective was to test whether food insecurity mediates cross-sectional associations between social disadvantage and body composition among older adults (aged 50+) in India (n = 6556). METHODS: Adjusting for key sociodemographic and dietary variables, we examined whether markers of social disadvantage (lower educational attainment, lower household wealth, belonging to a disadvantaged caste/tribe, and belonging to a minority religion…

  • Physical function and activity among older adults in Jodhpur, India

    This study provides further evidence for a positive relationship between physical activity and functional ability among older adults and between physical activity and cardiovascular health among women in India

  • Overcoming barriers to health-care access

    Open AccessLavinia Lin, Katherine B Brown et al.ARTICLEGlobal Public Health2015Cited by: 4References: 1

    Guangzhou is China's third most populous city, and the region's burgeoning manufacturing economy has attracted many young African businessmen and entrepreneurs to the city. The aims of this study were to examine strategies that African migrants in Guangzhou have adopted in response to health-care barriers, and explore their perceptions of how to address their needs. Twenty-five semi-structured interviews and two focus groups were conducted among …
