Research interests

The focus of Dr. Young’s work is on the reduction of maternal and child-undernutrition in the first 1000 days, especially in low-resource settings. Methodologically, she draws on her training in medical anthropology (MA, University of Amsterdam), international nutrition (PhD, Cornell) and HIV (Fellowship, University of California San Francisco) to take a biocultural approach to understanding how mothers in low-resource settings cope to preserve their health and that of their families.

Water Insecurity. Which experiences of water insecurity are universal? How can we best measure these? Problems with water quality and quantity are increasing in frequency and severity throughout the world. High-resolution, globally comparable data that go beyond physical availability to assess access and use have been extremely helpful for understanding the human health impact of other health issues, e.g. food insecurity, but have not existed for water. To fill this gap, Young. has led the development of the Household Water Insecurity Experiences (HWISE) and the Individual Water Insecurity Experiences (IWISE) scales, the first cross-culturally equivalent way of measuring water access and use (hwise.org). These scales have been implemented in at least 50 countries by more than 100 governmental, policy, research, and civil organizations. The Young Research Group is currently using these scales to estimate the prevalence of water insecurity globally, and to investigate its causes and consequences.

Food Insecurity. What role does food insecurity play in adverse maternal and child health and nutritional outcomes—especially when mothers and children are living with HIV? What are the types and magnitude of effects—and which of these are modifiable? How can food insecurity be mitigated amongst women and children in low-resource settings? To answer these questions, members of the Young Research Group have conducted observational and intervention studies in Tanzania, Kenya, and Uganda.

Pica (Non-Food Cravings). Is pica—the craving and consumption of non-food items such as earth, charcoal, and ice—an adaptive response to health challenges? What is the relationship between pica and iron deficiency? Using data from East Africa, North America, and elsewhere, researchers have long observed that non-food cravings and iron deficiency are associated, but the nature of the relationship is unclear. Young has used a variety of in vitro and in vivo animal studies, as well as observational studies in human and nonhuman primates, to ascertain the mechanisms underlying this observation, and to test the two major physiological hypotheses about pica: supplementation and detoxification.

Teaching 

Recent classes taught include “Water insecurity: anthropological and global health perspectives”; “Ecology of infant feeding”; and “Turning your numbers into a story”. She also teaches as part of the Northwestern Prison Education Program.
