Given the rapid pace and expanding reach of globalization, stress represents an important biological pathway by which economic and cultural transitions affect health, reflects changes in quality of life, and by which emerging inequalities may become instantiated in physiology. This doctoral study utilizes an objective biomarker of the stress response, cortisol, the key end product of the Hypothalamic-Pituitary-Adrenal axis, to evaluate the health impact of rapid cultural, economic, and lifestyle change among the Tsimane', a small-scale hunting and foraging society in the Bolivian Amazon (N=416, ages 2-82). The specific objectives of this study are: (1) to document variation in the diurnal (daily) cortisol rhythms among Tsimane' by age and by gender, and to compare these data to those derived from other population based studies of cortisol; (2) to explore the effect of market integration and culture change, through the utilization of a unique measure of economic stratification, income inequality, on differential patterns in the stress response and; (3) to investigate cortisol as a predictor of downstream health outcomes of child growth and development.

520 $a Given the rapid pace and expanding reach of globalization, stress represents an important biological pathway by which economic and cultural transitions affect health, reflects changes in quality of life, and by which emerging inequalities may become instantiated in physiology. This doctoral study utilizes an objective biomarker of the stress response, cortisol, the key end product of the Hypothalamic-Pituitary-Adrenal axis, to evaluate the health impact of rapid cultural, economic, and lifestyle change among the Tsimane', a small-scale hunting and foraging society in the Bolivian Amazon (N=416, ages 2-82). The specific objectives of this study are: (1) to document variation in the diurnal (daily) cortisol rhythms among Tsimane' by age and by gender, and to compare these data to those derived from other population based studies of cortisol; (2) to explore the effect of market integration and culture change, through the utilization of a unique measure of economic stratification, income inequality, on differential patterns in the stress response and; (3) to investigate cortisol as a predictor of downstream health outcomes of child growth and development.
520 $a The findings of this study are significant in several ways: first, distinct patterns of HPA activity were positively associated with age, with overall cortisol levels and slopes increasing from childhood through adulthood. Females exhibit elevated cortisol levels compared to males at every age. From a comparative perspective, the Tsimane' demonstrate among the lowest cortisol profiles on record: thus, a novel model for developmental programming of the HPA in response to restricted energy is discussed. In addition, an ecological gradient of proximity to the market center was inversely associated with mean cortisol, whereas the village level measure of income inequality was associated with reduced morning waking cortisol, thereby flattening the diurnal slope. Finally, controlling for illness, elevated cortisol levels were associated with reduced stature in both stunted and nonstunted children, but only for children under the age of 6.
520 $a By explicitly linking such macroscale changes to the individual differences in the stress response, and tracing the related health risk, this project simultaneously addresses the upstream factors, current lived experience, and the downstream consequences of stress among the Tsimane'.
