In Portugal, no relevant epidemiologic data exists relative to the management and level of control of diabetic patients.
TEDDI, a non-interventional cross-sectional study, allowed to characterize the usual management of type 1 (T1D) and type 2 (T2D) diabetes using a standardized questionnaire in 1775 patients (F: 47.5%; T2D: 80.8%) aged 18 years or older, visiting their diabetes specialist (n=180).
Data was obtained for metabolic control and risk factor prevalence. Main results are as follows (CI 95%):
|n||HTN, %||High LDL, %||Low HDL, %||High TGs, %||non-FBG, mg/dl||HbA1c, %|
|T1D, 336||29.9 (25.235.0)||30.8 (26.036.0)||36.6 (31.542.0)||16.5 (12.920.9)||176.4 (±85.9)||8.0 (±1.7)|
|T2D, 1395||70.1 (67.772.4)||51.2 (48.553.9)||40.6 (38.043.3)||35.0 (32.537.5)||183.7 (±73.0)||7.6 (±1.5)|
Severe hypoglycaemic crises (requiring emergency care) were reported by 3.4% of patients (T1D: 7.5%; T2D: 2.3%) in the preceding month. In these, an average of 2.4 crises per patient was determined.
In T2D, level of insulinization was 47.0%, and 31% were treated simultaneously with oral hypoglycaemic, antihypertensive, antidyslipidemic and anti-platelet drugs. In T1D, 16.1% of patients used LA insulin, while metformin was used as an adjuvant therapy in 15.2%.
Although old barriers in diabetes management (insulin for T2D and LA insulin and metformin for T1D) are overcome, metabolic control is still below expectations.
