Forced expiratory volume in 1 second and cognitive aging in men.
OBJECTIVES To evaluate forced expiratory volume in 1 second (FEV(1) , a measure of overall lung function), long-term average FEV(1) , and rate of decline in FEV(1) in relation to cognition and cognitive decline in older men. DESIGN Prospective observational study. SETTING Community-based population. PARTICIPANTS Eight hundred sixty-four older men from the Normative Aging Study. MEASUREM...
متن کاملEffort and the forced expiratory volume in one second (FEV).
1. The relationship between volumes expired and the maximum intrathoracic pressures developed within the first second of expiration was examined in a group of healthy subjects and patients with airways obstruction who exhaled with varying degrees of effort. 2. The body plethysmographic method was used to ensure that expirations started from total lung capacity. 3. Three different types of volum...
متن کاملForced expiratory volume in one second: why dichotomise?
Numerous epidemiological surveys have tried to evaluate the effects of exposures relevant to pulmonary disease.' A number of studies have analysed forced expiratory volume in one second (FEVI) using linear regression analysis, thus enabling adjustment for age, height, and sex as well as potential confounding variables. Within the last few years, studies analysing dichotomous FEV, variables with...
متن کاملSources of variation in forced expiratory volume in one second and forced vital capacity.
Published prediction equations for lung function differ considerably, but the components of population variation responsible for the differences are unknown. Data were analysed for 6,323 never-smoking adults who did not report wheeze or asthma, from 42 centres participating in the European Community Respiratory Health Survey. Means and components of variance were estimated for males and females...
متن کاملChanges in forced expiratory volume in 1 second over time in COPD.
BACKGROUND A key feature of chronic obstructive pulmonary disease (COPD) is an accelerated rate of decline in forced expiratory volume in 1 second (FEV(1)), but data on the variability and determinants of this change in patients who have established disease are scarce. METHODS We analyzed the changes in FEV(1) after administration of a bronchodilator over a 3-year period in 2163 patients. A r...
