An evolutionary biologist, Dr. Vitzthum’s work of the past 20 years has focused on the determinants of variation in human female reproductive functioning. During the mid-90s at the Bolivian Institute for High Altitude Biology, Vitzthum directed Project REPA, a longitudinal study of hormonal variation in highland Bolivian women. Vitzthum found unequivocally that lower hormone levels were normal for Bolivian women. Despite living at a high altitude and consuming an average of only 1800 calories a day, they were able to conceive with lower hormone levels than are considered normal for American women.
Vitzthum’s most recent work is focused on the causes of this hormonal variation. In 2006 she studied nomadic Mongolian herders, whose caloric intake is similar to Bolivians but whose consumption of animal fat is closer to that of Americans. She spent last year at the Max Planck Institute for Evolutionary Anthropology in Leipzig, measuring hormone levels in women born in the former East and West Germanys, where both diet and activity patterns differed before reunification.
“What we eat and what we do is at the heart of the intersection between biology and culture. Especially important is whether an adult experience of diet and exercise differs dramatically from one experienced in childhood. Who we are as adults is very much a reflection of who we were as children.”
Vitzthum sees her work as a bridge to the world of applied health policy such as to contraceptive technology, where less hormonal variation among woman and populations is assumed than her research indicates.
