Professor of Anthropology


Biography

As a biological anthropologist with training in epidemiology, Kuzawa’s research focuses on the role that the intrauterine and early postnatal environments have on development and long-term health. The premise of this research, supported by studies in both human populations and animal models, is that what a mother eats during pregnancy, her access to adequate prenatal care, or her level of stress, may permanently affect offspring biology in a fashion that influences risk for the most common causes of adult morbidity and mortality, including hypertension, diabetes, and heart attacks. This is a novel example of what is known as ‘developmental plasticity’, or the sensitivity of the developing body to the environment experienced during early stages of development. 

Current Research

Early Nutrition, Growth, and Aging in the Philippines. Since 1998, Kuzawa has worked with collaborators at the University of North Carolina, Chapel Hill and at the University of San Carlos, Cebu City (Philippines), on the Cebu Longitudinal Health and Nutrition Survey, one of the few studies in a developing nation capable of exploring this problem with longitudinal data extending back to pregnancy. The study enrolled more than 3,000 pregnant mothers in 1983 and has since followed both the mothers and their offspring, who are now young adults having children of their own. The results of this research suggest that the nutritional and lifestyle changes underway in the Philippines are likely to have more adverse effects on health among individuals who were born small or to mothers who were undernourished during pregnancy. Current research, supported by the National Institutes of Health, is using longitudinal data to evaluate the impact of early environments on cardiovascular risk in young adulthood and the determinants of healthy aging in the mothers’ generation.

Psychobiology of Social Relationships and Fatherhood. Research on bird and mammal species in which males provide care shows that testosterone is often regulated in response to breeding opportunities and parenting status. Kuzawa and his students and collaborators have explored the role of social context as an influence on male reproductive hormone regulation among the nearly 800 young men in the Cebu Study. This is among the largest study of its kind and has now tracked these men longitudinally to evaluate how social context, fatherhood, and hormonal status influence each other as men age. In 2013, funding from the National Science Foundation allowed Kuzawa and his collaborators to document stability and change in hormonal profiles in males as they age, as well as evaluate the impact that paternal care has on child development and school performance in their children.

Interdisciplinary Center for Health Disparities Research. Working with other IPR faculty fellows from several departments, Kuzawa is part of Cells to Society (C2S): The Center on Social Disparities and Health, a research center that aims to promote interdisciplinary approaches to the study of social disparities and health at Northwestern.
