[Hypertension in the elderly in France: Characteristics of treatments and frequency of cognitive complaint according to the 2014 French League against Hypertension Survey]

Abstract

Objective: Describe hypertensive patients treated in 2014 in France by age and estimate the degree of cognitive complaint among subjects aged 55 and over.

Method: French League against Hypertension Survey (FLAHS) was conducted by mail in a representative sample of subjects aged 35 and over living in metropolitan France. Antihypertensive treatment data were obtained by self-administered questionnaire. Among the owners of a self-measurement device, blood pressure was considered to be controlled if the average of three measurements in the morning was below 135/85 mmHg. Cognitive complaint was detected by the cognitive complaint questionnaire (QPC) and analyzed by age and medical history of each subject.

Results: In 2014, 30% of the population aged 35 and over (11.6 million) was treated with antihypertensive drugs. The number of treated hypertensive was: 3.45 million in the 75 and older, 2.96 million in 65-74 years, 3.24 million in 55-64 years, 1.58 million in the 45-54 years and 0.441 million in 35-44. The mono/bi/tri/quad-therapy is used in 46%/35%/14%/5% of patients. This distribution varies with age with monotherapy used in 63% of subjects under 55 years but in 40% of subjects 75 years and over. A positive QPC was noted in 11% of 55-64 years, in 21% of 75 years and older (P<0.001), in 20% of uncontrolled hypertensive patients, and in 34% of subjects with a personal history of stroke.

Conclusion: In France, hypertension is a disease that affects mainly the elderly. The modalities of treatment are different depending on age. Cognitive complaints are more common in uncontrolled hypertensive patients and in patients with a history of stroke.
