Salivary progesterone levels and rate of ovulation are significantly lower in poorer than in better-of urban-dwelling Bolivian women
(Human Reproduction, 2002)
Agriculturalists in less-developed countries (LDC) have lower progesterone levels than urban industrialized populations. However, it is unknown if urban LDC populations are also relatively lower. We tested whether urban ...
Effect of high altitude on protein metabolism in Bolivian children
(High Altitude Medicine & Biology, 2002-08-01)
Abstract.
In Bolivia, malnutrition in children is a major health problem that may be caused by inadequate protein, energy, and micronutrient intake; exposure to bacterial and parasitic infections; and ...
Effect of menstrual cycle phase on exercise performance of high-altitude native women at 3600 m
(The Journal of Experimental Biology, 2002)
Summary.
At sea level normally menstruating women show
increased ventilation (VE) and hemodynamic changes due
to increased progesterone (P) and estrogen (E2) levels
during the mid-luteal (L) compared to the mid-follicular
(F) ...

Seasonal and circadian variation in salivary testosterone in rural Bolivian men
(American Journal of Human Biology, 2009-02-19)
Abstract.
Testosterone (T) plays a key role in the increase and maintenance of muscle mass and bone density in
adult men. Life history theory predicts that environmental stress may prompt a reallocation of such investments ...

Effect of developmental and ancestral high-altitude exposure on chest morphology and pulmonary function in andean and european/north american natives
(American Journal of Human Biology, 1999)
Abstract.
Chest depth, chest width, forced vital capacity (FVC), and forced expiratory volume (FEV1) were measured in 170 adult males differing by ancestral (genetic) and developmental exposure to high altitude (HA). A ...
Effects of coca chewing on hormonal and metabolic responses during prolonged sbmaximal exercise
(J Appl Physiol, 1996)
Abstract
The effects of coca chewing on prolonged submaximal exercise responses were investigated in chronic coca chewers and compared with a group of nonchewers. At rest, coca chewing during a 1-h period was followed by ...
