    • Determinants of blood oxygenation during pregnancy in Andean and Europeas residents of high altitude 

      Vargas, Marco; Vargas, Enrique; Julian, Colleen Glyde; Armaza, J Fernando; Rodríguez, Armando; Téllez, Wilma; Niermeyer, Susan; Wilson, Megan; Parra, Esteban; Shriver, Mark; Moore, Lorna G (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 ...

    • Greater uterine artery blood flow during pregnancy in multigenerational (Andean) than shorter-term (European) high-altitude residents 

      Wilson, Megan J; López, Miriam; Vargas, Marco; Julian, Colleen Glyde; Téllez, Wilma; Rodríguez, Armando; Bigham, Abigail; Armaza, J Fernando; Niermeyer, Susan; Shriver, Mark; Vargas, Enrique; Moore, Lorna G (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 ...

    • High-altitude ancestry protects against hypoxia-associated reductions in fetal growth 

      Julian, Colleen Glyde; Vargas, Enrique; Armaza, J Fernando; Wilson, Megan J; Niermeyer, Susan; Moore, Lorna G (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 ...

    • Uterine artery blood flow during pregnancy in high-altitude aymara women 

      Wilson, Megan; Niermeyer, Susan; Armaza, J Fernando; López, Miriam; Vargas, Enrique; Moore, Lorna G (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 ...
