Abstract:
This study investigated and compared levels of fasting plasma glucose (FBS),
Homeostasis model assessment of the insulin resistance (HOMA), lipid profile, insulin, and
resistin hormones in 202 individuals that allowed into 4 groups. The groups were persons
with diabetes mellitus who were over nourished (DM/OB) or who had normal nutritional
status (DM/nOB), who were volunteers from a diabetes mellitus out patient clinic of the
Burapha university health center, Thailand. A control group of people without diabetes
and with normal nutritional status (nDM/nOB) or over nourished (nDM/OB) were healthy
volunteers from 3 villages around the health center. The male-female ratio for each group
was 8: 42 except for the DM/OB group with a ratio of 8: 44. Between all obese and non
obese groups, all of the anthropometric variables, except height, were significantly
different. Energy intake tended to be higher in the two groups with obese individuals. The
plasma concentrations of triglyceride (TC) and low density lipoprotein cholesterol (LDL),
but not high density lipoprotein cholesterol (HDL), were significantly higher in the two
groups with obese subjects. The TG levels among the nDM/OB, DM/nOB, and DM/OB
groups did not significantly differ, but were significantly higher than for the nDM/nOB
group. The median FBS level for the groups was lowest in the nDM/nOB group. There was
no difference for plasma insulin levels between the 4 groups, except that the individuals
within the DM/OB group had significantly higher insulin levels in comparison with the
other three groups. The HOMA score was significantly higher in the diabetes mellitus
groups, both obese and non obese. The lowest median level of plasma resistin was in the
nDM/nOB group, and levels were higher for the nDM/OB, raised again for the DM/nOB,
and highest levels were in the DM/OB group. The medians between the two DM groups
were not significantly different but between the nDM/OB and the DM/OB groups were
differed significantly, whereas the medians between group nDM/OB and DM/nOB did not
differ significantly. Obviously the combination of overnutrition and DM results in the
highest plasma resisitin concentrations. When participants of the groups nDM/nOB and
DM/nOB were pooled into one group and the subjects of the nDM/OB and DM/OB groups
combined into another group, the median plasma resistin levels between the 2 groups were
significantly different from each other and this result was also obtained when forming two
additional groups consisting out of nDM versus DM subjects. A significant correlation of
plasma resistin with BMI, waist circumference, waist to hip ratio, fasting plasma glucose
level, and HOMA score could be observed after conducting the Spearman’s Rank
correlation test, but not with plasma insulin levels and triceps skinfold thickness. The result
suggest that plasma resistin might take some role in linking central obesity and obesityrelated
insulin resistance in human to type II diabetes mellitus.
