Breastfeeding; Child health; Nutrition; Obesity
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 Council and the vice-chair for its Minority Affairs Committee.Impact of diabetes peer counseling on behavioral and metabolic outcomes among Latinos with type 2 diabetes (Randomized Controlled Trial)
