Research Summary

My global public health nutrition research program seeks to understand how best to: a) promote breastfeeding and other infant feeding practices; b) measure household food insecurity; c) mitigate the negative impact of household food insecurity on maternal-child physical and mental health outcomes; d) mitigate the negative impact of maternal HIV on child growth and development; d) design community nutrition education programs. My domestic health disparities research program focuses on design and evaluation of community health worker models seeking to improve behavioral (nutrition, physical activity, self-glucose monitoring, medication adherence) mental health (stress reduction) and metabolic outcomes among Latinos with type 2 diabetes.

Extensive Research Description

Rafael Perez-Escamilla is a professor of epidemiology and the director

of the office of community health at the Yale School of Public Health. Dr. Perez-Escamilla’s global public

health nutrition research program seeks to understand how best to promote

breastfeeding and to measure household food insecurity. He researches how to mitigate the

negative impact of this food insecurity on maternal-child health outcomes and

the impact of maternal HIV on child growth and development. Dr. Perez-Escamilla also leads a

domestic health disparities research program focused on designing and

evaluating community health worker models seeking to improve behavioral and

metabolic outcomes among Latinos with type 2 diabetes.



Dr. Perez-Escamilla received his M.S. and Ph.D. from the University of

California at Davis. He leads the

Latin American and Caribbean Household Food Security Scale project. He has published over 100 research

articles that have led to improvements in breastfeeding promotion, iron deficiency

anemia among infants (by delaying the clamping of the umbilical cord after

birth), household food security measurement and community nutrition education

programs worldwide. Dr.

Perez-Escamilla was a Pan American Health & Education Foundation trustee and

was appointed by the U.S. Secretaries of Agriculture and Health to serve on the

2010 Dietary Guidelines Scientific Advisory Committee. He is the

chair-elect of the American Society for Nutrition’s International Nutrition
