Essential to exposome research is the collection of data on many environmental exposures from different domains in same subjects. The aim Human Early Life Exposome (HELIX) study was measure and describe multiple during early life (pregnancy childhood) a prospective cohort associate these with molecular omics signatures child health outcomes. Here, we recruitment, measurements available baseline HELIX populations.The represents collaborative project across six established ongoing longitudinal...
The predicted extreme temperatures of global warming are magnified in cities due to the urban heat island effect. Even if target for average temperature increase Paris Climate Agreement is met, during hottest month a northern city like Oslo rise by over 5 °C 2050. We hypothesised that heat-related diagnoses heat-sensitive citizens (75+) correlated monthly air temperatures, and green infrastructure such as tree canopy cover reduces land surface thus health risk from exposure. Monthly were...
<h3>Objectives</h3> Limited evidence suggests adverse effects of traffic noise exposure on the metabolic system. This study investigates association between road and obesity markers as well role combined to multiple sources noise. <h3>Methods</h3> In a cross-sectional performed in 2002–2006, we assessed from traffic, railways aircraft at residences 5075 Swedish men women, primarily suburban semirural areas Stockholm County. A detailed questionnaire medical examination provided information...
Ambient air pollution has been associated with lung cancer, but the shape of exposure-response function - especially at low exposure levels is not well described. The aim this study was to address relationship between long-term low-level and cancer incidence.The "Effects Low-level Air Pollution: a Study in Europe" (ELAPSE) collaboration pools seven cohorts from across Europe. We developed hybrid models combining monitoring, land use data, satellite observations, dispersion model estimates...
Characterization of the "exposome", set all environmental factors that one is exposed to from conception onwards, has been advocated better understand role on chronic diseases. Here, we aimed describe early-life exposome. Specifically, focused correlations between multiple exposures, their patterns and variability across European regions time (pregnancy childhood periods). We relied Human Early-Life Exposome (HELIX) project, in which 87 exposures during pregnancy 122 period (grouped 19...
The exposome is defined as the totality of environmental exposures from conception onwards. It calls for providing a holistic view and their effects on human health by evaluating multiple simultaneously during critical periods life.We evaluated association urban with birth weight.We estimated exposure to exposome, including built environment, air pollution, road traffic noise, meteorology, natural space, (corresponding 24 indicators 60 exposures) nearly 32,000 pregnant women six European...
The aims of the present study were to investigate how nighttime road traffic noise relates self-reported symptoms insomnia and sleep medication use.We used questionnaire data from population-based Health Environment in Oslo (HELMILO) (2009-2010; n = 13019). difficulties falling asleep, awakenings during night, waking up too early morning as well use included outcomes. Modeled levels (Lnight) assigned each participant's home address. For selecting covariates statistical model, we a directed...
Air pollution has been classified as carcinogenic to humans. However, date little is known about the relevance for cancers of stomach and upper aerodigestive tract (UADT). We investigated association long‐term exposure ambient air with incidence gastric UADT cancer in 11 European cohorts. was assigned by land‐use regression models particulate matter (PM) below 10 µm (PM ), 2.5 between coarse PM absorbance nitrogen oxides (NO 2 NO X ) well approximated traffic indicators.

Green spaces may have beneficial impacts on children's cognition. However, few studies explored the exposure to green beyond residential areas, and their availability, accessibility uses at same time. The aim of present study was describe patterns accessibility, among primary school children explore how these dimensions are associated with cognitive development. Exposures space near home, school, commuting route, other daily activity locations were assessed for 1607 aged 6-11 years from six...
An increasing number of children are exposed to road traffic noise levels that may lead adverse effects on health and daily functioning. Childhood is a period intense growth brain maturation, therefore be especially vulnerable noise. The objective the present study was examine whether associated with reported inattention symptoms in children, this association mediated by sleep duration.This based Norwegian Mother Child Cohort Study conducted Institute Public Health. Parental reports...
Urban environmental design is increasingly considered influential for health and wellbeing, but evidence mostly based on adults single exposure studies. We evaluated the association between a wide range of urban environment characteristics behaviours in childhood.We estimated to 32 (related built environment, traffic, natural spaces) home school addresses 1,581 children aged 6-11 years from six European cohorts. collected information including total amount overall moderate-to-vigorous...
The majority of studies have shown higher greenness exposure associated with reduced mortality risks, but few controlled for spatially correlated air pollution and traffic noise exposures. We aim to address this research gap in the ELAPSE pooled cohort. Mean Normalized Difference Vegetation Index (NDVI) a 300-m grid cell 1-km radius were assigned participants' baseline home addresses as measure surrounding exposure. used Cox proportional hazards models estimate association NDVI natural-cause...
Background: Hearing impairment is one of the most common permanent disabilities in western world. Although hearing ability normally declines with age, there great individual variation age onset, progression, and severity, indicating that susceptibility plays a role. The aim present study was to explore relative importance genetic environmental effects etiology impaired hearing. Methods: From August 1995 June 1997, total adult population Nord-Trøndelag County, Norway, invited take part Health...
Almost half of the European Union (EU)’s population is exposed to road traffic noise above levels that constitute a health risk. Associations between and impaired sleep in adults have consistently been reported. Less known about effects on children’s sleep. The aim this study was examine association nocturnal exposure parental-reported duration problems. present cross-sectional used data from Norwegian Mother Child Cohort Study. Parental report problems at age 7 linked modelled residential...
To assess the role of occupational noise exposure on pregnancy complications in urban Nordic populations. A study population covering five metropolitan areas Denmark, Finland, Norway and Sweden was generated using national birth registries linked with residential environmental exposures sociodemographic variables. The data covered all pregnancies during 5-11 year periods 2004‒2016, resulting 373 184 pregnancies. Occupational based a Swedish-developed job-exposure-matrix, containing measured...
