[Number and use of home blood pressure devices in France in 2004 and 2006 (FLAHS 2006)].

Abstract

OBJECTIVES To estimate the number and the using modalities of devices for home blood pressure (HBP) measurements in the French population in 2006 and to evaluate the trend of these data over the past two Years. METHODS The French League Against Hypertension Surveys have been performed both in 2004 and 2006 (FLAHS-2006) by an independent company (TNS-SOFRES) within a representative sample of French population older than 35 and living in metropolitan France. The surveys involved 3707 and 3389 subjects, respectively. A questionnaire evaluating ownership, kind and using modalities of HBP device was given. Subjects who declared taking an antihypertensive medication were classified as treated hypertensive patients. The data from the INSEE census performed in1999 allowed for an estimate of the total number of HBP devices owned by French people. RESULTS In 2006, 19% of the French population above the age of 35 years owned a HBP device, a rate reaching 36% in treated hypertensives versus 11% in the rest of the population (p<0.001). In 2004, the ownership rates were 24% and 7%, respectively. It could be estimated that about 6 million HBP devices were owned by French people in 2006, meaning an increase of 2 million devices, as compared with 2004 survey. 53% of BP devices were equipped with an arm cuff in 2006, versus 33% only, in 2004. Device purchase has been made in 2006 either in a pharmacy (39%), or in a hypermarket (7%), or through the web (3%); they were given as a gift in 39%. Device use was indicated as regular by 30% of hypertensive patients and 23% of the rest of the people. Giving up was observed in 7% and 15%, respectively. CONCLUSION In 2006, about 6 million HBP devices are owned by French people; the rate of treated hypertensives owning a HBP device is 1/3. The huge increase in the number of HBP devices from 2004 to 2006 suggests that the recommendations of the French "Haute Autorité de Santé" as well as the national programs about HBP measurement have had a real impact on the use of this technique in France.
