High-altitude ancestry protects against IUGR and reductions in birth weight associated with high altitude and preeclampsia
(High Altitude Medicine & Biology, 2005-02-22)
Background.
Observations consistently demonstrate diminished birth weight [BW] with ascending altitude;
however population comparisons reveal the extent of BW
reduction depends, in part, upon high-altitude ancestry.

Índice de resistencia vascular arterial en la madre y el feto durante el embarazo en grandes alturas (3600 m) vs. niveles bajos de altura (300 m)
(Revista de la Sociedad Boliviana de Radiología, 2007)
Resumen.
Objetivo: Determinar los índices de resistencia de las arterias uterinas en las madres, umbilical y cerebral media en los bebés de grandes alturas, en comparación a pacientes que habitan alturas bajas reflejados ...
High-altitude ancestry protects against hypoxia-associated reductions in fetal growth
(Archives of Disease in Childhood-Fetal and Neonatal, 2007-02-28)
Objective: The chronic hypoxia of high-altitude (>2500 m) residence has been shown to decrease birth
weight in all populations studied to date. However, multigenerational high-altitude populations appear
protected relative ...
The role of oxygen in prenatal growth : studies in the chick embryo
(J Physiol, 2007-10-25)
The compelling evidence linking small size at birth with later cardiovascular disease has renewed
and amplified scientific and clinical interests into the determinants of fetal growth. It is accepted
that genes and ...
Seasonal modulation of reproductive effort during early pregnancy in humans
(American Journal of Human Biology, 2009-03-03)
Abstract.
Life history theory predicts that early pregnancy presents a relatively low cost, uncontested opportunity for a woman to terminate investment in a current reproductive opportunity if a conceptus is of poor quality ...
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 ...
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, ...

Pulmonary-artery pressure and exhaled nitric oxide in Bolivian and caucasian high altitude dwellers
(High Altitude Medicine & Biology, 2008)
Abstract.
There is evidence
that high altitude populations may be better protected from hypoxic pulmonary hypertension than low altitude natives, but the underlying mechanism is incompletely understood. In Tibetans, ...
