[Aterial hypertension and cardiovascular risk factors associated with diabetes. Report of the PHARE survey in general practice].

OBJECTIVE

To evaluate the characteristics of diabetic hypertensive patients (Pts), in term of associated cardiovascular risk factors and blood pressure control in a representative population issued from a survey "PHARE" conducted in general practice in France in 1999.

DESIGN AND METHODS

PHARE survey was conducted in a sample of 225 GPs representative of the French medical population included in a gallup poll. GPs had to include all patients > 18 years old over a period of one week. Pts were considered as hypertensives (HP) if the mean of two recorded BP measurements was = 140/90 mmHg and/or < 140/90 mmHg if they were under antihypertensive treatment. Patients were considered as diabetics if they were previously known and/or if they received a medication for diabetes. Hypertensives were considered as controlled if their BP levels were overall < 140/90 mmHg or at the recommended threshold < 130/85 mmHg under treatment.

RESULTS

877 diabetic Pts (7%) among 12.342 Pts and 5.190 HP were included in the study. When compared to normotensives, diabetic HP had more frequently associated risk factors with hypertension and diabetes: overweight 71% vs 45%, dyslipidemia 61% vs 34%, sendentarily 73% vs 63%, tobacco consumption 27% vs 20%. The BP control at 140/90 mmHg threshold among treated diabetic HP was 21%, and only 8% at 130/85 mmHg. Regarding WHO classification, 79% of these diabetics had a high or very high cardiovascular risk. The were no difference in antihypertensive drugs used in HP diabetics and non diabetics and 50% of them received ACEI.

CONCLUSIONS

8 from 10 diabetics taken in charge in general practice are hypertensives and 8 from 10 have a very high cardiovascular risk due to a poor BP control and associated cardiovascular risk factors.
