During the economic crisis, fruit and vegetable consumption alarmingly decreased, especially among those of lower SES, whereas trends in smoking prevalence and physical activity levels seem favourable. These results indicate that the economic crisis may unequally impact cardiovascular risk factors among different socio-economic groups.

INTRODUCTIONThis paper provides an up-to-date summary of the effects of smoking in pregnancy as well as challenges and best practices for supporting smoking cessation in maternity care settings.METHODSWe conducted a qualitative review of published peer reviewed and grey literature.RESULTSThere is strong evidence of the effects of maternal tobacco use and secondhand smoke exposure on adverse pregnancy outcomes. Tobacco use is the leading preventable cause of miscarriage, stillbirth and neonatal deaths, and evidence has shown that health effects extend into childhood. Women who smoke should be supported with quitting as early as possible in pregnancy and there are benefits of quitting before the 15th week of pregnancy. There are a variety of factors that are associated with tobacco use in pregnancy (socioeconomic status, nicotine addiction, unsupportive partner, stress, mental health illness etc.). Clinical-trial evidence has found counseling, when delivered in sufficient intensity, significantly increases cessation rates among pregnant women. There is evidence that the use of nicotine replacement therapy (NRT) may increase cessation rates, and, relative to continued smoking, the use of NRT is considered safer than continued smoking. The majority of women who smoke during pregnancy will require support throughout their pregnancy, delivered either by a trained maternity care provider or via referral to a specialized hospital or community quit-smoking service. The 5As (Ask, Advise, Assess, Assist, Arrange) approach is recommended for organizing screening and treatment in maternity care settings. Additionally, supporting smoking cessation in the postpartum period should also be a priority as relapse rates are high.CONCLUSIONSThere have been several recent updates to clinical practice regarding the treatment of tobacco use in pregnancy. It is important for the latest guidance to be put into practice, in all maternity care settings, in order to decrease rates of smoking in pregnancy and improve pregnancy outcomes.

Compliance with laws making certain environments smoke free has focused mainly on smokers' behavior, while the role of non-smokers has scarcely been investigated. Our cross-sectional study interviewed 4043 adults (2037 smokers and 2006 non-smokers) in the general population of Greece during April 2009. Non-smokers reported that they would actively work for compliance with the law. The non-smokers were older, more educated (odds ratio, OR 1.4), and were more likely to be annoyed by the smell of environmental tobacco smoke (OR 2.4) or report that it irritates their eyes (OR 1.8). Policymakers should evaluate how non-smokers could actively support smoke-free laws through reporting of violations using media campaigns that inform them of their rights, and other measures.
