Current state of metabolic control achieved in a New Zealand diabetes clinic

To report on current degree of metabolic control achieved in diabetic patients in a New Zealand diabetes clinic.

All metabolic data were reviewed for patients attending the Waikato diabetes clinic from 1 January 1992 to 1 January 1995. Values were obtained from 409 insulin treated patients (IDDM), with a mean age of 39 (SD 15 yr); 200 patients who transferred from diet or pills to insulin (NIDDM-I) with a mean age of 59 (SD 12 yr); and 290 noninsulin dependent patients (NIDDM), mean age 54 (SD 13 yr). Results. Percentage of fructosamine values in the normal range: IDDM 10%, NIDDM-I 12.5% and NIDDM 37.9%. Mean values (SD). IDDM group: fructosamine 376 (78) mmol/L, cholesterol 5.24 (1.1) mmol/L, HDL cholesterol 1.47 (0.45) mmol/L, triglycerides 1.71 (1.35) mmol/L. NIDDM-I group: fructosamine 359 (67) mmol/L, cholesterol 5.82 (1.1) mmol/L, HDL cholesterol 1.21 (0.45) mmol/L, triglycerides 2.92 (3.8) mmol/L. NIDDM group: fructosamine, 312 (73) mmol/L, cholesterol 5.83 (1.24) mmol/L, HDL cholesterol 1.1 (0.33) mmol/L, triglycerides 3.11 (3.59) mmol/L. Percentage of smokers in each group: IDDM 24%, NIDDM-I 8.5%, NIDDM 17.2%.

the majority of patients fail to achieve normal fructosamine values. Lipid control is poor, other than in the IDDM group. A significant number of patients continue to smoke. Considerable scope for improvement is noted.
