Andean women have greater uterine artery (UTA) enlargement during pregnancy than european residents of 3600 m.
([s.n.], 2003)
Abstract.
Babies weigh less at high altitude but multi-generational high-altitude residents are protected from this birth weight decline (Moore HAMB 2001). Objective: We asked if higher arterial oxygenation and/or blood ...
Comparative aspects of high-altitude adaptation in human populations
(Adv. Exp. Med. Biol., 2000)
Abstract.
The conditions and duration of high-altitude residence differ among high-altitude populations. The Tibetan Plateau is larger, more geographically remote, and appears to have been occupied for a longer period of ...
Perinatal hypoxia increases susceptibility to high-altitude polycythemia and attendant pulmonary vascular dysfunction
(Am J Physiol Heart Circ Physiol, 2015-04-27)
Perinatal hypoxia increases susceptibility to high-altitude polycythemia and
attendant pulmonary vascular dysfunction. Am J Physiol Heart Circ
Physiol 309: H565–H573, 2015. First published June 19, 2015;

Andean compared with european women are protected from altitude-associated intrauterine growth restriction (IUGR)
(s.n., 2003)
Abstract.
Babies born at high altitude to long-term high-altitude residents weigh more than those of recent migrants from low altitude. Objective: We asked whether a gradient exists such that persons of Andean ancestry ...
Human physiological adaptation to pregnancy : inter- and intrspecific perspectives
(American Journal of Human Biology, 2003)
Abstract.
Reproductive success requires successful maternal physiological adaptation to pregnancy. An interspecific perspective reveals that the human species has modified features of our haplorhine heritage affecting ...
Development of a panel of genome-wide ancestry informative markers to study admixture throughout the Americas
(PLOS Genetics, 2012-03-08)
Abstract.
Most individuals throughout the Americas are admixed descendants of Native American, European, and African ancestors.
Complex historical factors have resulted in varying proportions of ancestral contributions ...
Sleep-disordered breathing and oxidative stress in preclinical chronic mountain sickness (excessive erythrocytosis)
(Respiratory Physiology & Neurobiology, 2013-01-22)
Abstract.
Chronic mountain sickness (CMS) is considered to be a loss of ventilatory acclimatization to high
altitude (>2500 m) resulting in marked arterial hypoxemia and polycythemia. This case-control
study explores ...
Graduated effects of high-altitude hypoxia and highland ancestry on birth size
(Pediatric Research, 2013-10-02)
Background: We present a cohort of ca. 25,000 birth
records from Bolivia of men and women who are currently
adults. We used this cohort to test the hypothesis that high
altitude reduces birth weight and that highland ...
Potential role for elevated maternal enzymatic antioxidant status in Andean protection against altitude-associated SGA
(The Journal of Maternal-Fetal and Neonatal Medicine, 2012)
Oxidative stress has been implicated in the uteroplacental
ischemia characteristic of preeclampsia and small-for-gestational-age (SGA) birth, both of which are more common at high
(>2500 m) vs low altitude. Since Andeans ...
Uterine artery blood flow, fetal hypoxia and fetal growth
(Philosophycal Transactions B, 2015-03-13)
Evolutionary trade-offs required for bipedalism and brain expansion influence
the pregnancy rise in uterine artery (UtA) blood flow and, in turn, reproductive
success. We consider the importance of UtA blood flow by ...
