This study investigated the association between biomarkers of fetal exposure to cigarette smoke at the end of pregnancy, cotinine in cord serum and in maternal and newborn urine samples, and quantitative measurement of smoking intake and exposure evaluated by maternal self-reported questionnaire. Study subjects were 429 mothers and their newborns from a(More)
UNLABELLED This study examined indoor nitrogen dioxide (NO2) concentrations in Ashford, Kent (UK), Menorca Island and Barcelona city (Spain) and the contribution of their most important indoor determinants (e.g. gas combustion appliances and cigarette smoking). The homes examined (n = 1421) were those from infants recruited for the Asthma Multicentre(More)
Arsenic is a highly toxic element that pollutes groundwater, being a major environmental problem worldwide, especially in the Bengal Basin. About 40% of patients in our outpatient clinics come from those countries, and there is no published data about their arsenic exposure. This study compares arsenic exposure between immigrant and native children. A total(More)
BACKGROUND Over the last few years a decreasing trend in smoking has occurred not only in the general population but also during pregnancy. Several countries have implemented laws requiring all enclosed workplace and public places to be free of second hand smoke (SHS). In Spain, legislation to reduce SHS was implemented in 2005. The present study examines(More)
BACKGROUND Awareness of the negative effects of smoking on children's health prompted a decrease in the self-reporting of parental tobacco use in periodic surveys from most industrialized countries. Our aim is to assess changes between ETS exposure at the end of pregnancy and at 4 years of age determined by the parents' self-report and measurement of(More)
BACKGROUND AND OBJECTIVES To analyse the relationship between prenatal and postnatal tobacco exposure and the development of respiratory and allergy symptoms during the first 4 years of life. PATIENTS AND METHODS Prospective and multicentred cohort study that included the subjects belonging to AMICS (Asthma Multicentred Infant Cohort Study) located in(More)
INTRODUCTION There is limited knowledge on the relationship between lower respiratory tract infections (LRTI) and asthma and wheezing during infancy, as there are few studies with prospective design, birth cohort and in non selected population. The objectives of the present study were to determine the prevalence of asthma and recurrent wheezing in childhood(More)
BACKGROUND Nitrogen dioxide (NO(2)) has been related to respiratory infections in experimental studies but its role remains controversial in general population studies of children. We aim to assess the association between indoor NO(2) and lower respiratory tract infections (LRTI) during the first year of life in a multicentre prospective cohort study. (More)
BACKGROUND Smoking during pregnancy poses a health risk for the fetus which may later extend to the child and adult, with higher probability of respiratory problems. The aim of this study was the to investigate the correlation between smoking during pregnancy and the neonatal characteristics and sociodemographic determinants of smoking habit during(More)
Objective: To examine smoking habits before and during pregnancy, as well as factors associated with smoking cessation, in three European settings. Methods: Women seeking antenatal care in Ashford (UK), Minorca and Barcelona (Spain) were recruited to the Asthma Multicenter Infant Cohort Study (AMICS). Questionnaires inquiring into the smoking habits of each(More)
