Factors associated with second-hand smoke exposure in non-smoking pregnant women in Spain: self-reported exposure and urinary cotinine levels.

2014

The aim of this study was to evaluate the main sources of and sociodemographic factors associated with second-hand smoke (SHS) exposure, assessed both by questionnaire and by urinary cotinine (UC) levels, in non-smoking pregnant women. We conducted a cross-sectional study in pregnant women from 4 different regions in Spain. A total of 1783 non-smoking pregnant women completed a questionnaire about their previous smoking habit and SHS exposure in their 3rd trimester of pregnancy and provided a urine sample for measuring UC levels. We used logistic regression models to assess the relationship between several sociodemographic variables and some potential sources of SHS exposure. In addition, w…

DNA methylation patterns in newborns exposed to tobacco in utero

2015

[Background] Maternal smoking during pregnancy is a major risk factor for adverse health outcomes. The main objective of the study was to assess the impact of in utero tobacco exposure on DNA methylation in children born at term with appropriate weight at birth.

Current active and passive smoking among adults living with same sex partners in Spain

2018

Objective: To assess the association between current active and passive tobacco smoking and living with a same-sex partner in Spain. Methods: We analysed data from two cross-sectional national surveys of the Spanish population 15 years and older (2011-Encuesta Nacional de Salud en España and 2014-Encuesta Europea de Salud en España). Analyses included only people living with their partner. Associations were calculated using multiple logistic regressions adjusting for gender, social class and age. Results: Current active and passive smoking were significantly associated with living with same sex partners (odds ratio: 2.71 and 2.88), and particularly strong among women. Conclusions: Spanish a…

Association of mental distress with smoking status in the community: Results from the Gutenberg Health Study.

2013

Abstract Background Exposition to tobacco smoke is among the major modifiable risk factors in the general population. There is strong evidence for a close association between smoking exposure and mental disorders. Methods Cross-sectional associations of different conditions of smoking status (former, current, and second hand smoking (SHS)) with indicators of mental distress were analyzed in a sample of N =5000 participants (aged 35–74 years) of the population-based survey “Gutenberg Health Study”. Results In the general population clinically significant depression (OR 1.59, 95%CI 1.17–2.17) and a previous diagnosis of depression (OR 1.50, 95%CI 1.16–1.94) were associated with current smokin…

Prenatal exposure to cooking gas and respiratory health in infants is modified by tobacco smoke exposure and diet in the INMA birth cohort study

2013

Background: Studies that have evaluated the association between exposure to gas appliances emissions at home with respiratory health in children obtained heterogeneous and limited results. The aim of this study is to analyze the association between the use of gas cooking at home during pregnancy and respiratory problems in children during their first year of life. Methods: In the years 2003 through 2008 pregnant women were enrolled in 4 Spanish areas and visited in different age-points following a common protocol. Outcomes studied (from a questionnaire) were any episode of lower respiratory tract infection (LRTI), wheezing, persistent cough, chestiness and otitis. The association between ex…

High cotinine levels are persistent during the first days of life in newborn second hand smokers.

2013

a b s t r a c t Background: Despite the adverse effects of maternal smoking during pregnancy on the newborn's health are well-known, in the pediatric population, a high prevalence exists that is very much affected by second hand smoke (SHS). This study aims to investigate the impact of maternal smoking habits during preg- nancy on cotinine levels in newborns during the first days of life. The high association between cotinine concentration in maternal and umbilical cord blood (UCB) has been previously reported, but the levels of blood cotinine that remain in infants born to smokers is unknown. Methods: Cotinine concentration was measured in UCB, in maternal and newborn peripheral blood. Dat…

Association between passive tobacco exposure and caries in children and adolescents. A systematic review and meta-analysis.

2017

To examine the available evidence on the association between exposure to tobacco use in the womb and in infancy and the presence of caries in primary and permanent dentition in children and adolescents. A systematic review was conducted through searches in 4 data bases (Pubmed, Scopus, Embase and Web of Science), complemented by hand-searching. Of the 559 articles identified, 400 were duplicates. Finally, 28 articles were included in the qualitative review and 21 in the meta-analysis. Their quality was assessed using the Newcastle-Ottawa scale. The quality was medium in 44% of the articles included and high in 56%. The overall meta-analysis gave a significant odds ratio (OR = 1.53, 95% conf…

Passive exposure to nicotine from e-cigarettes

2016

A procedure based on the use of ion mobility spectrometry (IMS), after liquid-liquid microextraction (LLME), has been successfully employed for the determination of passive exposure to nicotine from cigarette and e-cigarette smoking. Nicotine has been determined in exhaled breath and oral fluids of both, active and passive smokers. The aforementioned studies, made in closed environments, evidenced that the exhaled breath after conventional blend cigarette smoke provides nicotine levels of the order of 220 ng per puff, in the case of experienced smokers, being exhaled only 32 ng in the case of e-cigarettes. On the other hand, the nicotine amount in oral fluids of passive vapers was between 8…

Tobacco use in the third trimester of pregnancy and its relationship to birth weight. A prospective study in Spain

2015

Abstract Background Few studies have been carried out in Spain examining the use of tobacco amongst expectant mothers and its effect on birth weight. Aims To observe the proportion of expectant mothers who smoke during their pregnancy, and the impact of tobacco consumption on maternal and birth weight. We also aimed to identify the trimester of pregnancy in which tobacco use produced the greatest reduction in birth weight. Methods Prospective observational study in Spain. A random sampling strategy was used to select health centres and participant women. A total of 137 individuals were enrolled in the study. Exposure to tobacco was measured through a self-reported questionnaire. Regressions…
