Effects of filter choice in GT3X accelerometer assessments of free-living activity (Publications)
PURPOSE: Actigraph accelerometers are widely used devices to objectively assess physical activity. The GT3X version has two filter options to be selected prior to data assessment (normal and low frequ
Predictors of methacholine responsiveness in a general population (Publications)
OBJECTIVE: Methacholine responsiveness is an end point widely used in epidemiologic studies of asthma. This study aims to quantify the relative importance of different predictors of responsiveness suc
Glutathione S-transferase polymorphisms, passive smoking, obesity, and heart rate variability in nonsmokers (Publications)
BACKGROUND: Disturbances of heart rate variability (HRV) may represent one pathway by which second-hand smoke (SHS) and air pollutants affect cardiovascular morbidity and mortality. The mechanisms are
Ten-year follow-up of cluster-based asthma phenotypes in adults: a pooled analysis of three cohorts (Publications)
Rationale: The temporal stability of adult asthma phenotypes identified using clustering methods has never been addressed. Longitudinal cluster-based methods may provide novel insights in the study of
Genome-wide association studies identify CHRNA5/3 and HTR4 in the development of airflow obstruction (Publications)
RATIONALE: Genome-wide association studies (GWAS) have identified loci influencing lung function, but fewer genes influencing chronic obstructive pulmonary disease (COPD) are known. OBJECTIVES: Perfor
What physical activity surveillance needs: validity of a single-item questionnaire (Publications)
BACKGROUND: Self-report instruments to assess physical activity are still the most feasible option in many population-wide surveys, and often need to be very short owing to resource constraints. The a
Natural-cause mortality and long-term exposure to particle components: an analysis of 19 European cohorts within the multi-center ESCAPE project (Publications)
BACKGROUND: Studies have shown associations between mortality and long-term exposure to particulate matter air pollution. Few cohort studies have estimated the effects of the elemental composition of
The association between road traffic noise exposure, annoyance and health-related quality of life (HRQOL) (Publications)
The aim of this study is to investigate the relationships between road traffic noise exposure, annoyance caused by different noise sources and validated health indicators in a cohort of 1375 adults fr
Transportation noise and blood pressure in a population-based sample of adults (Publications)
Background: There is some evidence for an association between traffic noise and ischemic heart disease, however associations with blood pressure have been inconsistent and little is known about health
