Non-insulin-dependent diabetes mellitus (NIDDM) is a serious health problem
among the Zuni Indians of New Mexico. In July 1983, Indian Health Service
personnel initiated a community-based exercise program designed to help
control NIDDM in the community. To retrospectively evaluate the effects of
the exercise program, the medical records of 30 participants with NIDDM
were compared with the medical records of 56 nonparticipants with NIDDM
matched by age, sex, health-care provider, and duration of NIDDM. From 1
July 1983 through 1 October 1985, participants had a mean weight loss of 4
kg, whereas nonparticipants had a mean weight loss of 0.9 kg (P less than
.05). Participants' fasting blood glucose values dropped by a mean of 43
mg/dl, compared to a mean drop of 2 mg/dl among the nonparticipants (P less
than .05). Participants were significantly more likely than nonparticipants
to have stopped their hypoglycemic medication (relative risk 4.2) and to
have decreased their medication dosage (relative risk 2.2). These results
suggest that participation in a community-based exercise program can
produce significant weight loss and improvement in glycemic control among a
group of Native Americans with NIDDM.
