They live under woefully desperate conditions, but street children may be better off than once thought. New findings, presented at the annual gathering of the American Association of Physical Anthropologists in Buffalo, N.Y., bolster previous work suggesting that homeless urban children are actually healthier and more likely to survive than are their peers who grow up in poor but intact families in agricultural villages.

Timothy Sullivan of the University at Buffalo measured body mass index (BMI)--the ratio of weight to height--in 50 Guatemalan street children ages five to 15. BMI correlates with mortality and morbidity from a number of causes, predicting among other things impaired maternal health and fetal growth, diminished work capacity and productivity and high rates of chronic disease. Although the study subjects were shorter and weighed less than American children of similar ages, their BMI scores were comparable.

"The business of being a street urchin, of making a living on the street, seems to work better for these children than we might anticipate," remarks University at Buffalo anthropologist A.G. Steegman. "Their health as measured by their BMIs doesn't prove they lead a fine life--it is fraught with great danger, including murder and sexual exploitation, especially for the girls--but it does confound our expectations." Such urban homeless children appear to trade off the long-term psychosocial costs of their plight against short-term survival benefits, he adds. "These kids are resilient and self-reliant and adapt physically to the difficult conditions of homelessness."

She is fascinated by human origins, which she has covered for nearly 30 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home to the shores of Kenya’s Lake Turkana in search of the oldest stone tools in the world, as well as to Madagascar on an expedition to unearth ancient mammals and dinosaurs, the icy waters of Antarctica, where humpback whales feast on krill, and a “Big Day” race around the state of Connecticut to find as many bird species as possible in 24 hours. Wong is co-author, with Donald Johanson, of Lucy’s Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
