Type 2 daibetes mellitus (T2DM) is a global concern boosted by both population growth and ageing, the majority of affected people are aged between (40- 59 year). The objective of this research was to estimate the impact of age and gender on glycaemic control parameters: Fasting blood glucose (FBC), glycated hemoglobin (HbA1C), insulin, insulin resistance (IR) and insulin sensitivity (IS), renal function parameters: urea, creatinine and oxidative stress parameters: total antioxidant capacity (TAC) and reactive oxygen species (ROS). Eighty-one random samples of T2DM patients (35 men and 46 women) were included in this study, their average age was 52.75±9.63 year. Current study found that FBG, HbA1C and IR were highly significant (P<0.01) increased by increasing age. The lowest level of FBG was in the age group 30-39 years, which was a high significant (P<0.01) lower than other age groups 40-49, 50-59 and ³ 60 years. The highest level of HbA1C was in advanced age group ³ 60years, which was significantly (P<0.01) highest than other groups 30-39, 40-49 and 50-59 years. The highest level of IR was in the older age group ³ 60 years, which was significantly (P<0.01) highest than other age groups 30-39, 40-49 and 50-59 years. Insulin hormone level showed no significant (P>0.05) differences between age groups. Insulin sensitivity decreased in older age group ³ 60years compared with the other age groups with a highly significant differences. The results shows a highly significant (P<0.01) increasing in levels of urea and creatinine with increasing age. The lowest level of urea was found in 30- 39 and 40-49 year compared with other age groups, highest levels of creatinine were in 50-59 and ³ 60 age groups, which were significantly (P<0.01) highest than 30-39, 40-49 years age groups. In present study, the levels of TAC decreased by age. Third age group 50-59 showed the lowest level of TAC, which was significantly (P<0.05) lower than other age groups 30-39, 40-49 and ³ 60 years. Statistical analysis showed that the level of ROS was significantly (P<0.05) increased in advanced age groups 50- 59 and ³ 60years compared with other age groups 30-39 and 40-49 years. Statistical analysis revealed a significant (P<0.05) increased in levels of FBG in women compared with men, while insignificant differences (P>0.05) found in the HbA1c and insulin levels. A highly significant (P<0.01) increased in IR value was also found in women compared with men. Also, statistical analysis show that IS value was significantly decrease in women compared with men. The statistical analysis showed a nonsignificant differences for increasing levels of urea in women compared to men, while current finding showed a highly significant (P<0.01) increase in creatinine levels in men as compared with women. The present study showed insignificant increasing in the mean of TAC in men compared to women. While, the mean of ROS was significantly (P<0.05) increase in women compared to men.
