[Clinical interventions on the major vascular risk factors (RIVANA study)]

To describe the diagnostic frequency of classical vascular risk factors, dietary and therapeutic interventions and their control.

Within the project Vascular Risk in Navarre (RIVANA), a transversal study was made of a random sample of 4,354 people between the ages of 35 and 84; antecedents were gathered by interview and clinical and analytical exploration was carried out. The subjects were classified for each risk factor into: diagnosed by information--when health personnel had informed them that they presented a risk factor; by intervention--when they take medication for it; and by detection in asymptomatic people. The variables of intervention were identified by dichotomic trees expressed by relative frequencies.

Forty-five point three percent of the subjects are hypertense: 27% previously diagnosed and 18.3% at the time of the exploration. Thirty-nine percent are hypercholesterolemic: 33.4% previously diagnosed and 5.6% at the time of the exploration. Twenty-one point two percent presented hyperglycemia: 9.7% previously diagnosed and 11.6% at the time of the exploration. Sixty-five point six percent were diagnosed as overweight or obese: 25.9% previously and 39.6% at the time of the exploration. They received dietary counselling and pharmacological treatment respectively: 79.8% and 70.3% of the hypertense; 75.4% and 35% of the hypercholesterolemic; 83.1% and 47.4% of those who presented hyperglycemia and 68.5% and 4% of those who showed overweight or obesity.

The frequency of cardiovascular risk factors is high. There is a margin for significant improvement in the detection, intervention and control of the risk factors.
