Impact of age, gender, diabetes mellitus duration and body mass index on metabolic control of type 2DM among a group of Jordanian patients

الملخص EN

Objectives : to assess the impact of age, gender, duration of diabetes and body mass index confounders on diabetes control among a Jordanian cohort of T2DM at the Endocrine Clinic in King Hussein Medical Center.

Methods : patients were selected over 18 months from outpatient clinic at King Hussein Medical Center in Amman-Jordan.

Diabetes control assessed by mean of latest 3 HbA1c and fasting blood sugar.

Patients were divided in 2 groups according to age (< 55 years Vs > 55 years), gender, duration (< 10 years Vs > 10 years) and BMI (normal, overweight, and obese according to WHO criteria).

Statistical analysis is performed using SPSS11.5.Good diabetes control is assessed according to American Diabetes Association criteria Results : A total of 405 patients were selected (223 males, 182 females).

115 patients (28.4 %) were having a good control with HbA1c < 7 %.

; 25.6 % of males and 31.9 % of females were having good control (P value = 0.161).

There was no difference in diabetes control of those < 55 years (n = 183) Vs those >55 years (n = 222) (29 % vs.28 % ; p = 0.812).

Females in both age groups were having non statistically significant better control than males.

Of those with DM duration < 10 years (n = 242) ; 34.7 % were having good control vs.

only 19 % for those > 10 years duration (n = 163) {P-value = 0.001, RR = 1.83, OR = 2.26}.

Females were again having a better diabetic control in both duration groups, p = 0.024.

There was no statically significant difference in diabetic control in all BMI categories studied.

Thirty percent of overweight patients were having good control Vs < 20 % in normal and obese patients.

The mean HBA1c in males was 8.1 ± 1.7 % Vs 7.9 ± 1.5 % in females.

For the group < 10 year, HBA1c was 7.75 ± 1.5 % Vs 8.32 ± 1.54 % in those > 10 year.

The mean HBA1C of the group aged < 55 years was 8.1 ± 1.8 Vs 7.9 ± 1.5 in those > 55 years of age.

Conclusion : in this Jordanian group with T2DM the diabetic control was modest at 28.4 %.

Females were having a better diabetic control at all categories.

Diabetes duration less 10 years was the only indicator of adequate control of diabetes.
