Andean women have greater uterine artery (UTA) enlargement during pregnancy than european residents of 3600 m.
Moore, Lorna G; Wilson, Megan; López, Miriam; Vargas, Marco; Parra, Esteban; Niermeyer, Susan; Aramaza, J Fernando; Vargas, Enrique ([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 ... -
Augmented uterine artery blood flow and oxygen delivery protect andeans from altitude-associated reductions in fetal growth
Julian, Colleen Glyde; Wilson, Megan J; López, Miriam; Yamashiro, Henry; Téllez, Wilma; Rodríguez, Armando; Bigham, Abigail W; Shriver, Mark D; Rodríguez, Carmelo; Vargas, Enrique; Moore, Lorna G (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 ... -
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 ... -
Reduced endothelin-1 (ET-1) and elevated nitric oxide metabolites (NOX) across pregnancy among andean vs. european women at high (3100-3600 m) altitude
Julian, Colleen Glyde; Wilson, Megan; Vargas, Enrique; Vargas, Marco; López, Miriam; Niermeyer, Susan; Moore, Lorna G (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 ... -
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 ...
