The electronic cigarette (EC) has become popular among smokers who wish to reduce their tobacco use levels or quit smoking, but its effectiveness as a cessation aid is uncertain.To examine the association of regular EC with number cigarettes smoked per day, smoking current smokers, and relapse former smokers.The CONSTANCES (Consultants des Centres d'Examens de Santé) cohort study, based in France, began recruiting participants January 6, 2012, currently ongoing. Participants were enrolled...

The current evidence on health effects of long-term exposure to outdoor airborne black carbon (BC) remains scarce.To examine the association between BC and mortality in a large population-based French cohort, with 28 years follow-up.Data from GAZEL cohort were collected 1989 2017. Land use regression model temporal extrapolation wa used estimate yearly PM2.5 at residential addresses until censoring for 19,906 participants. Time-varying Cox models attained age as time-scale was associations...

BACKGROUND: Black carbon (BC), a component of fine particulate matter [particles with an aerodynamic diameter ≤2:5 lm (PM 2:5 )], may contribute to carcinogenic effects air pollution.Until recently however, there has been little evidence evaluate this hypothesis.OBJECTIVE: This study aimed estimate the associations between long-term exposure BC and risk cancer.This was conducted within French Gazel cohort 20,625 subjects.METHODS: We assessed by linking subjects' histories residential...

To examine the cross-sectional and longitudinal associations between depressive symptoms electronic cigarette (e-cig) use in a large population-based sample while taking into account smoking status sociodemographic confounders. Participants from French Constances cohort were included February 2012 to December 2016. Smoking status, e-cig (never/ever/current) nicotine concentration self-reported. Depressive measured with Center for Epidemiologic Studies Depression (CES-D) scale. Logistic...

Few studies have reported the association between air pollution exposure with different dimensions of depression. We aimed to explore this across depressive symptoms in a large population.Data from enrollment phase French CONSTANCES cohort (2012-2020) were analyzed cross-sectionally. Annual concentrations particulate matter diameter < 2.5 µm (PM2.5), black carbon (BC), and nitrogen dioxide (NO2) land-use regression models assigned residential addresses participants. Total its four (depressed...

The specific compounds that make ambient fine particulate matter (PM2.5) carcinogen remain poorly identified. Some metals contribute to PM2.5 and possibly its adverse effects. But the challenge of assessing exposure airborne limits epidemiological studies. To analyze relationships between several risk cancer in a large population. We estimated individual 12 ∼ 12,000 semi-urban rural participants French population-based Gazel cohort using moss biomonitoring data from 20-year national program....

Long-term exposure to air pollution affects health, but little is known about atmospheric metals. Estimating metals across large spatial areas remains challenging. Metal concentrations in mosses could constitute a useful proxy. Here, we linked moss biomonitoring and epidemiological data investigate the associations between long-term mortality. We modelled mapped 13 from 20-year national program derive estimates France. In population-based Gazel cohort, included 11,382 participants low...

Background The asthma symptom score allows to consider as a continuum and investigate its risk factors. One previous study has investigated the association between air pollution only for nitrogen dioxide (NO 2 ). We aimed associations particulate matter with an aerodynamic diameter lower than 2.5 µm (PM ), black carbon (BC) NO in adults from CONSTANCES, French population-based cohort. Methods Asthma (range: 0–5) was based on number of five self-reported symptoms last 12 months. Annual...

Trihalomethanes (THMs) and nitrate are widespread chemicals in drinking water. Chronic exposure has been associated with increased cancer risk despite inconclusive evidence, partly due to the challenges long-term assessment potential misclassification. We estimated concentrations of THMs water using a public regulatory monitoring database (SISE-Eaux) for CONSTANCES, French population-based prospective cohort. obtained 26,322,366 measurements parameters from 2000 2020. excluded missing,...

Exposure of the general population to airborne metals remains poorly estimated despite potential health risks. Passive moss biomonitoring can proxy air quality at fine resolution over large areas, mainly in rural areas. We adapted technique urban areas develop concentration maps for several Constances cohort's participants. sampled Grimmia pulvinata 77 and 51 cemeteries within ∼50 km Paris Lyon city centers, respectively. developed land-use regression models 14 including cadmium, lead,...
