Biocultural Anthropology student Masako Fujita combines labwork with cultural research in northern Kenya
Doctoral student Masako Fujita will travel to Kenya this summer to begin the first phase of her dissertation
research on Vitamin A transfer from mothers to children in breastmilk.
Fujita, who has previously done research in Kenya with CSDE affiliate
Eric Roth (University of Victoria), will be
collecting cultural and contextual information about women’s dietary norms, preferences, and constraints in this
first phase. She will also be working out the logistics for the second phase: how to store and transport serum
and breastmilk samples from lactating mothers in rural Kenya, where there is little or no electricity, back to
UW for analysis.
As a biocultural anthropology student, Fujita combines labwork with cultural research. Her interest in the
impact of lifestyle changes on maternal health is especially relevant to the population with which she will be
working: The Ariaal and Rendille population of northern Kenya has undergone a lifestyle change in recent years
from nomadic to sedentary, affecting their diet and habits. In addition, their cultural practices discourage
women from consuming meat and blood, which are significant sources of dietary vitamin A.
The goal of her study is to investigate the relationships and trade-offs between maternal vitamin A status,
maternal health, and child survival in the cultural and ecological context of northern Kenya.
Vitamin A deficiency, estimated by healthworkers to be high in the Ariaal and Rendille population, increases
the risk of infection and death by compromising the immune system. In addition, the WHO also calls it
"the leading cause of preventable blindness in
children." However, vitamin A supplementation to correct this deficiency must be carefully done. High
doses of vitamin A to pregnant women can cause birth defects, and high doses to infants and children can have
severe toxic side effects. Research also shows that even when mothers have adequate vitamin A stores, vitamin
A concentrations in breastmilk decline in the first several months after giving birth. Adopting the concept of
tradeoffs from life history theory, Fujita hypothesizes that this decline may occur because the body reallocates
vitamin A away from breastmilk to the liver for maternal survival and future reproduction.
Since coming to UW in 2001, Fujita has worked in the
CSDE Biodemography Lab on a number of projects,
most recently to validate assays for measuring vitamin A and C-reactive protein. She also helps train students
in the lab in proper technique and practices.
Fujita has received several fellowships and grants to help support her research on maternal health in the
Ariaal and Rendille of northern Kenya, including funds from the Puget Sound Partners for Global Health, the
Social Sciences and Humanities Research Council of Canada, the UW Graduate School, and the Department of
Anthropology.
