Abstract

Respiratory ageing raises for the epidemiologists many questions still unsolved by clinical and physiological approaches: prevalence of chronic respiratory diseases, consequences on autonomy, risk factors. This paper aims to provide some responses based on a wide sample of elderly people: the PAQUID cohort. PAQUID is a cohort of 3777 dwellers representative of the population aged 65 and over in two administrative areas of south-western France. The study is based on general variables as well as specific variables identifying dyspnea, asthma, chronic bronchitis and their risk factors. Disability was measured using specific scales. Mortality is registered during the follow-up. Twenty-five percent of subjects had a dyspnea for minor efforts (level 3 and over). There was a significant relationship between dyspnea and disability levels for basic and instrumental activities of daily living. Mortality rate was significantly associated to dyspnea level of the subjects at inclusion in the cohort, especially in men, even taking into account other mortality related risk factors (sex, smoking, occupation). 6.1% of the subjects reported symptoms of asthma. But only 2.5% reported symptoms in the twelve last months. The follow-up has shown new...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
