ABSTRACT

Objective:

To explore the relationship between sex hormone binding globulin and glycolipid metabolism in patients with obese polycystic ovary syndrome.

Methods:

From April 2016 to April 2019, 114 patients with obese polycystic ovary syndrome in the Integrated Chinese and Western Medicine Hospital of Wenzhou were selected and divided into two groups according to the level of sex hormone binding globulin, including 66 cases in the low level group and 48 cases in the normal group.The blood glucose, blood lipid and sex hormone levels of the two groups were measured and the results were analyzed.

Results:

The levels of TC, TG, LDL-C and ApoB in the low level group[(2.32±0.97)mmol/L, (6.45±1.25)mmol/L, (3.57±1.01)mmol/L, (0.93±0.32)g/L] were significantly higher than those in the normal group[(1.87±0.89)mmol/L, (4.88±0.94)mmol/L, (3.12±0.88)mmol/L, (0.76±0.17)g/L]( t=2.477-7.322, all P<0.05). The level of ApoA in the low level group[(1.22±0.34)g/L] was significantly lower than that in the normal group[(1.58±0.47)g/L]( t=-4.748, P<0.05), while there was no statistically significant difference in HDL-C between the two groups[(1.45±0.31)mmol/L vs.(1.43±0.56)mmol/L, t=0.244, P>0.05]. The levels of FPG, HbA1C and FINS in the low level group[(5.53±1.45)mmol/L, (6.42±0.79)% and (18.71±5.46)mU/L] were significantly higher than those in the normal group[(5.09±0.76)mmol/L, (6.01±0.92)% and (15.49±4.98)mU/L]( t=2.136-3.225, all P<0.05), while there was no statistically significant difference in 2hPG between the two groups[(8.79±1.56)mmol/L vs.(8.32±1.84)mmol/L]( t=1.472, P>0.05). The incidence of insulin resistance in the low level group[54.55%(36/66)] was significantly higher than that in the normal group[35.42%(17/48)](χ 2=4.088, P<0.05). The level of T in the low level group[(61.45±21.44)ng/mL] was significantly higher than that in the normal group[(50.39±22.31)ng/mL]( t=2.673, P<0.05), while there were no statistically significant differences in FSH, LH, E 2 and PRL between the two groups( t=0.427-1.714, all P>0.05).

Conclusion:

The patients with low levels of sex hormone binding globulin are more likely to suffer from hyperglycemia and hyperlipidemia, and low levels of sex hormone binding globulin may be a risk factor for obese polycystic ovary syndrome.
