Objectives To describe the cultural context of type 2 diabetes mellitus amo
ng Vietnamese immigrants in the United States, including people's ideas abo
ut cause and proper treatment; and to suggest ways in which better control
of the disease can be achieved in this population. . Design The method was
ethnographic. A native speaker used a structured interview guide to talk wi
th 38 Vietnamese patients, and family members of 2 other patients, being tr
eated for type 2 diabetes. In addition, 8 Vietnamese health providers-5 phy
sicians, 2 nurses, and an herbalist-were interviewed. . Setting A low-incom
e area of southern California populated by a large number of Vietnamese. .
Participants Forty patients being treated for type 2 diabetes and 8 health
practitioners. . Results Three quarters of the patients had not achieved go
od control of their diabetes. Ideas about the cause and proper treatment of
the disease were culturally shaped. Many patients used eastern (herbal) me
dicine and described a strong aversion to insulin injections. Patients stop
ped taking their oral medications when using eastern medicine, and a quarte
r lowered their dose whenever they felt "out of balance." Almost two thirds
had used traditional home remedies for diabetes. Two had received nonstand
ard medical care from neighborhood physicians trained in Viet Nam; 1 of the
se patients died during the study. . Conclusion The Vietnamese community an
d physicians serving that community need culturally appropriate education a
bout type 2 diabetes and modem therapy for the disease.
