OBJECTIVE- To examine the incidence and determinants of elevated urina
ry albumin excretion in Pima Indians with non-insulin-dependent diabet
es mellitus (NIDDM). RESEARCH DESIGN IND METHODS- The incidence of ele
vated urinary albumin excretion (greater than or equal to 30 mg albumi
n/g creatinine) and its relationship with baseline characteristics was
determined in 456 Pima Indians greater than or equal to 15 years old
with NIDDM who were followed for up to 11.6 years (median 4.7 years).
RESULTS- Of these 456 subjects, 192 (42%; 58 men, 134 women) developed
elevated urinary albumin excretion, 172 of whom (90%) were within the
microalbuminuric range (30-299 mg/g). The incidence of elevated urina
ry albumin excretion was related to retinopathy, type of diabetes trea
tment, longer duration of diabetes, lower body mass index, and higher
values of mean arterial pressure, HbA,, and fasting and 2-h postload p
lasma glucose concentration at the baseline examination, but not to se
x. A relationship with cholesterol was found in durations of diabetes
of greater than or equal to 10 years. The cumulative incidence of elev
ated albumin excretion was 17% after 5 years of NIDDM. CONCLUSIONS- Th
e incidence of elevated urinary albumin excretion in Pima Indians with
NIDDM is at least as high as that reported previously in insulin-depe
ndent diabetes mellitus, and its major determinants are the same as th
ose shown previously to predict the development of more advanced renal
disease in this population.
