The spirometric measurement of pulmonary function by measuring the forced expiratory volume in one second (FEV1) is a heritable trait that reflects the physiological condition of the lung and airways. Genome-wide linkage and association studies have identified a number of genes and genetic loci associated with pulmonary function. However, limited numbers of studies have been reported for Asian ...
Spirometric lung function is partly determined by sex, age and height (Ht). Commonly, lung function is expressed as a percentage of the predicted value (PP) in order to account for these effects. Since the PP method retains sex, age and Ht bias, forced expiratory volume in 1 s (FEV(1)) standardised by powers of Ht and by a new sex-specific lower limit (FEV(1) quotient (FEV(1)Q)) were investigat...
OBJECTIVE To determine whether the level of physical activity in daily life (PADL) is associated with pulmonary function in adult smokers. METHODS We selected 62 adult smokers from among the participants of an epidemiological study conducted in the city of Santos, Brazil. The subjects underwent forced spirometry for pulmonary function assessment. The level of PADL was assessed by the Internat...
INTRODUCTION Association between obesity and asthma has been reported widely, with disparity between males and females. Epidemiological data which indicate that obesity precedes development of asthma and increases the prevalence and incidence of asthma, raises the possibility of a causal association. AIM To find out the association, including gender differences, between Body Mass Index (BMI) ...
Allergic occupational asthma is frequent in farming populations. As educational interventions can improve disease management, the short-term effect of an educational intervention in asthmatic farmers was evaluated on the basis of spirometric indices and exhaled nitric oxide fraction (F(eNO)). Farmers with occupational asthma (n = 81), mostly sensitised against cow dander and storage mites, part...
The single breath transfer factor for carbon monoxide (TLCO), TLCO/alveolar volume (VA), and standard spirometric indices were measured in a survey of the randomly selected population sample of 1174 subjects enrolled in the Tucson epidemiological study of airways obstructive disease. Subjects were subdivided according to whether the FEV1/FVC ratio was under 65%, 65-75%, or over 75%. The influen...
Spirometric obstruction is a prevalent problem in older adults and related to life-style risk factors. Symptoms related to chronic-obstructive-pulmonary-disease (COPD) are also prevalent symptoms with diverse etiologies - not limited to pulmonary obstruction. Older adults may have unrecognized airway obstruction due to functional limitations or symptoms mis-attributed to age/other co-morbiditie...
