Evidence that parent-of-origin affects birth-weight reductions at high altitude
(American Journal of Human Biology, 2008-02-19)
Abstract.
Hypoxia exerts a profound depressant effect on fetal growth, lowering birth weight, and raising mortality risk. Multigenerational high-altitude populations are relatively protected from this birth-weight decline, ...
Uterine artery blood flow during pregnancy in high-altitude aymara women
(High Altitude Medicine & Biology, 2003-02-19)
Background.
Birth weight falls with increasing altitude as the result of
intrauterine growth restriction (IUGR) likely due, in turn, to lower uterine artery (UtA) blood flow. The altitude-associated birth weight decline
is ...
Reduced endothelin-1 (ET-1) and elevated nitric oxide metabolites (NOX) across pregnancy among andean vs. european women at high (3100-3600 m) altitude
(High Altitude Medicine & Biology, 2005-02-22)
Background.
A consistent reduction in infant birth
weight occurs with ascending altitude; however multigenerational high-altitude residents [Andeans] demonstrate a degree of protection from altitude-associated
IUGR ...
Augmented uterine artery blood flow and oxygen delivery protect andeans from altitude-associated reductions in fetal growth
(Am J Physiol Regul Integr Comp Physiol, 2009-02-20)
Abstract.
The effect of high altitude on reducing birth weight is markedly less in
populations of high- (e.g., Andeans) relative to low-altitude origin
(e.g., Europeans). Uterine artery (UA) blood flow is greater ...
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 ...
Greater uterine artery blood flow during pregnancy in multigenerational (Andean) than shorter-term (European) high-altitude residents
(Am J Physiol Regul Integr Comp Physiol, 2007)
Multigenerational (Andean) compared with shorter-term (European) high-altitude
residents exhibit less hypoxia-associated reductions in birth
weight. Because differences in arterial O2 content are not responsible,
we ...
Determinants of blood oxygenation during pregnancy in Andean and Europeas residents of high altitude
(Am J Physiol Regul Integr Comp Physiol, 2007-07-02)
High altitude decreases birth weight,
but this effect is diminished in long vs. short-resident, high-altitude
populations. We asked whether women from long vs. short-resident,
high-altitude populations had higher arterial ...
