Abstract:
Objective:To study the changes of the serum zinc alpha 2 glycoprotein (ZAG) level in men and its relationship with blood lipid male reproductive hormones.
METHODS:We enrolled 297 men aged 25－ 65 years in this study, 152 with hyperlipemia (HL) and the other 145 with normal blood lipid (normal control). We divided them into four age groups (25－35 yr, 36－45 yr, 46－55 yr, and 56－65 yr) and three tertile groups (Q1, Q2, and Q3) according to the tertiles of the serum ZAG level, and examined their blood lipid, blood glucose, serum ZAG, and reproductive hormones.
RESULTS:The serum ZAG level was decreased gradually with the increase of age in both the HL patients and normal controls, significantly in the 36－45 and 56－65 yr age groups (P <0.05), and markedly lower in the HL than in the control men in the 25－35 and 36－45 yr groups (P <0.05). The levels of follicle-stimulating hormone (FSH) and total testosterone (TT) changed significantly with the ZAG level. The level of serum ZAG was correlated negatively with age (r = －0.58, P<0.05), waist circumference (r = －0.21, P <0.05), body mass index (BMI) (r = －0.22, P <0.05), fasting blood glucose (r = －0.16, P <0.05) , and triglyceride (TG) (r = －0.27, P <0.05) but positively with TT (r = 0.36, P <0.05). Age, BMI and TG were independent factors influencing the serum ZAG level.
CONCLUSIONS:The serum ZAG level is decreased with the increase of age and associated with lipid metabolism, abdominal obesity, and reproductive hormone levels in males.
