Agricultural
Research Service scientists have identified several nutritional
and physical activity factors that affect chronic health diseases
among American Indians.
Jacqueline
S. Gray, a postdoctorate researcher with the ARS Grand Forks Human
Nutrition Research Center (GFHNRC) in Grand Forks, N.D., used a
mobile nutrition research laboratory to access powwows and reservations
to collect data. This month, she returns to the tribes to present
research findings.
American
Indian tribes, considered sovereign domestic nations, are among
the most impoverished of minority groups in America. They experience
a disproportionately high incidence of diabetes, obesity and heart
disease. Native Americans also have the highest per-capita suicide
rate, nearly two-and-a-half times the national average and more
than four times the national average among 15- to 24-year-olds.
The
study was directed by psychologist James G. Penland and physiologist
Henry C. Lukaski with the center's Mineral Nutrient Functions Research
Unit. More than 60 percent of the survey participants indicated
they had a family member who had been diagnosed with diabetes. Food
insecurity was a problem among 26 percent of those surveyed. That
meant that during the previous 12 months, they had experienced various
degrees of limited or uncertain access to nutritionally adequate
and safe foods.
Depression-related
symptoms were found to be associated with poorer health, less exercise,
food insecurity, higher body mass index in females, carbohydrate
intake in males and tobacco use. Depression scores were highest
among those reporting lower income, more children, and food insecurity.
But they were lowest among those reporting a stronger identity with
their native culture.
The
resulting study data will be used for designing and implementing
effective interventions to improve health and quality of life among
American Indians. Gray and Penland are providing a technical report
to all participating tribal groups for their use when applying for
grant programs.
