OBJECTIVES This study aims to investigate the role of different factors associated with exposure to second-hand smoke (SHS) in the workplace and home in the urban and rural areas of India. DESIGN Secondary analysis of the data from the Global Adult Tobacco Survey conducted in 2009-2010. SETTING AND PARTICIPANTS Data were analysed from 32 738 rural and 23 202 urban non-smokers at home and 48...

BACKGROUND To describe the socio-demographic factors associated with exposure to second-hand smoke (SHS) in different settings (home, leisure, and workplace). METHODS We analysed cross-sectional data on self-reported SHS exposure in 1059 non-daily smokers interviewed in the Cornellà Health Interview Survey Follow-up Study in 2002. We calculated age-adjusted prevalence rates and prevalence rat...

OBJECTIVE To assess the impact of the 28/2005 Spanish smoking law on exposure to second-hand smoke (SHS) in Barcelona. METHODS We performed a pre-post evaluation study. Two cross-sectional surveys were compared. Data were obtained from the Barcelona Health Surveys of 2000 and 2006. The prevalence of SHS exposure among non-smoking adults was analyzed by setting (home, workplace and leisure tim...

Much evidence indicates that individuals use tobacco primarily to experience the psychopharmacological properties of nicotine and that a large proportion of smokers eventually become dependent on nicotine. In humans, nicotine acutely produces positive reinforcing effects, including mild euphoria, whereas a nicotine abstinence syndrome with both somatic and affective components is observed after...

Background: The effect of smoking cigarettes is followed by diverse effects on ovaries and developing follicles but the effect of passive smoking on ovarian function is unknown. On the other hand, the ovarian response to induction is a very important step in assisted reproduction. The aim of this study is to compare ovarian response in passive smokers and non-passive smokers in an assisted repr...

OBJECTIVES To examine changes in bar workers' exposure to second-hand smoke (SHS) over a 12-month period before and after the introduction of Scottish smoke-free legislation on the 26 March 2006. METHODS A total of 371 bar workers were recruited from 72 bars in three cities: Aberdeen, Glasgow, Edinburgh and small towns in two rural regions (Borders and Aberdeenshire). Prior to the introductio...

OBJECTIVES To examine whether second-hand smoke (SHS) exposure measured by serum cotinine is associated with increased coronary heart disease (CHD) and stroke risk among contemporary older British adults. DESIGN Prospective population-based study with self-reported medical history and health behaviours. Fasting blood samples were analysed for serum cotinine and cardiovascular disease (CVD) ri...

AIM To measure exposure to second-hand smoke (SHS) in New Zealand bars before and after comprehensive smoke-free legislation enacted on 10 December 2004. METHODS Cotinine is the main specific metabolite of nicotine and a well-established biomarker for SHS exposure. We measured cotinine levels in saliva of non-smoking volunteers before and after a 3 h visit to 30 randomly selected bars in 3 ci...

We used physical and pharmacokinetic modeling to estimate personal exposures to respirable particle (RSP) and carcinogenic particulate polycyclic aromatic hydrocarbon (PPAH) air pollution from second-hand smoke (SHS) from the increase in urinary cotinine of eight patrons of three bars in Bismarck, North Dakota. We compared SHS-RSP levels to the U.S. Air Quality Index (AQI), used to forecast out...

OBJECTIVES To assess the prevalence of children's exposure to second-hand smoke in the family car; to compare exposure among children with smoking and non-smoking parents. METHODS In 2011, a self-administered questionnaire was applied to a 4th grade Portuguese children national sample (N=3187, mean age 9.5 ± 0.7, 51.1% boys). Prevalence rates and chi-square tests were computed. RESULTS Of t...
