Background: The association between cigarette smoking and schizophrenia is well established. However, up to 90% of people with schizophrenia begin smoking before the onset of their illness; thus, smoking could be an independent risk factor for schizophrenia. Prenatal exposure to maternal cigarette smoke is also associated with psychiatric problems in adolescence. Therefore, our aim was to undertake a systematic review and meta-analysis to explore the effect of smoking, and prenatal smoke exposure, on risk of schizophrenia.Method: We systematically searched Medline, EMBASE, PsychInfo, Maternity and Infant Care, and Web of Science (from inception to February 2018) to identify comparative observational studies of the risk of schizophrenia in relation to smoking status. Measures of relative risk (RR) were pooled in a meta-analysis with 95% confidence intervals (CI), using random effects model.Results: Twelve studies (9 cohort, 3 case-control) were included. Odds ratios (OR) and hazard ratios (HR) were pooled together to estimate pooled relative risks and estimates combined in a meta-analysis on an assumption of constant risk over time. Smokers had a significantly increased risk of schizophrenia compared with nonsmokers (RR = 1.99, 95% CI = 1.10% to 3.61%, I2 = 97%, 5 studies). Exposure to prenatal smoke increased the risk of schizophrenia by 29% (95% CI = 1.10% to 1.51%, I2 = 71%, 7 studies). Sensitivity analyses identified no significant differences between the results from studies reporting OR and hazard ratio.Conclusions: Our findings suggest smoking, and prenatal smoke exposure, may be an independent risk factor for schizophrenia. Care should be taken when inferring causation, given the observational nature of the studies.Implications: In this meta-analysis of 12 studies, smokers had a significantly increased risk of schizophrenia compared with nonsmokers. Exposure to prenatal tobacco smoke also increased the risk of schizophrenia by 29% compared with those with no exposure to prenatal tobacco smoke. Our findings suggest that smoking, and prenatal tobacco smoke exposure, may be independent risk factors for schizophrenia. These results may have important public health implications for decreasing the incidence of schizophrenia. The possibility of a causal link between smoking and schizophrenia warrants further investigation.

Background: Existing evidence suggests that while the coronavirus disease 2019 (COVID-19) pandemic triggered quit attempts among many smokers, it led some to smoke more and others to relapse back to smoking. These diverse effects have the potential to have a long-term impact on individuals’ smoking and vaping behaviors. Aims and Methods: This study explored the effect of COVID-19 on smokers and vapers, vape shops (VS), and stop smoking services (SSS). A total of 39 semi-structured interviews were conducted with stop-smoking practitioners, tobacco control leads, smokers and/or vapers, and vape shop owners. Interviews were transcribed verbatim and analyzed thematically. Results: Four themes were identified: Lockdown as a barrier to becoming or remaining smoke-free; COVID as a catalyst for quitting and remaining smoke-free; changes in vaping and challenges for vapers and VS; and changes and challenges for stop smoking support. Fear of COVID resulting in severe health implications for smokers facilitated behavior change; however, the boredom and monotony of lockdown and associated stress created difficulties in remaining a smoke free. Results showed that the enforced switch from face-to-face to the remote provision of SSS was beneficial for improving engagement, particularly for vulnerable groups such as pregnant women. Stop smoking professionals and vapers disagreed with the forced closure of VS because it created unnecessary difficulties for vapers to access supplies. Conclusions: COVID-19 was both a barrier and facilitator for smoking cessation. Remote provision of SSS implemented due to lockdown was beneficial for hard-to-reach groups; services should look to incorporate these changes into day-to-day practice. Implications: This study is one of the first to explore how the COVID-19 pandemic directly affected smokers, vapers, SSS, tobacco control leads, and VS. It provides evidence for the continued use of the remote provision of smoking cessation services to increase engagement among hard-to-reach groups and provides information on how pandemics can be a catalyst for health behavior change. This study is unique in that it incorporates the views of different stakeholders.

Finding effective ways to help pregnant women quit smoking and maintain long-term abstinence is a public health priority. Electronic cigarettes (ie, vaping) could be a suitable cessation tool in pregnancy for those who struggle to quit; however, healthcare professionals (HCP) must be informed about these devices to offer appropriate advice. This study used the Capability, Opportunity, Motivation, and Behavior (COM-B) model and Theoretical Domains Framework (TDF) to explore HCP attitudes towards vaping in pregnancy and postpartum; beliefs about the health risks of vaping; perceived barriers and facilitators of vaping in pregnancy; knowledge of current guidelines and policies; and training needs. Interviews (n = 60) were conducted with midwives (n = 17), health visitors (n = 10), general practitioners (n = 15) and stop smoking specialists (n = 18) across the United Kingdom. Interview transcriptions were analyzed thematically using the framework approach and the COM-B. Discussing vaping as a tool for quitting smoking in pregnancy was prevented by a lack of capability (limited knowledge of vaping, lack of training in smoking cessation); lack of opportunity (restricted by organizational policies and guidelines, lack of time and financial issues impacting on training), and negative social influences (sensationalist media and stigma associated with vaping in pregnancy); and lack of motivation (fear of future litigation and comebacks should adverse effects from vaping arise). Factors related to capability, opportunity, and motivation were identified that influence HCPs attitudes and behaviors towards vaping in pregnancy. Gaps in knowledge and training needs were identified, which could inform the development of targeted vaping training. Vaping could be suitable in pregnancy for those struggling to quit smoking. However, HCPs must be informed about these devices to offer appropriate advice. These data extend our knowledge of factors influencing HCP attitudes and behaviors towards vaping in pregnancy. Generally, vaping was perceived as safer than cigarettes, but a perceived lack of evidence, health and safety risks, dependency, and regulation issues were concerning. Considering our findings, greater efforts are needed to ensure HCPs are sufficiently informed about vaping and guidelines available. More importance should be placed on training for all HCPs who have contact with pregnant women.

Objective: Noise-induced hearing problems among young adults are increasing due to participation in loud activities. This study explored attitudes towards leisure noise, hearing protection, and perceived susceptibility to noise damage in young adults with no diagnosed hearing problems. Understanding attitudes and behaviours will assist with the future development of strategies to improve awareness and use of hearing protection. Design: A qualitative study. Study sample: Four focus groups, with 28 adults aged 18–35 years (6 male; 22 female; mean age 23 years). Results: Using framework analysis, five themes emerged. Earplug use occurred when participants had experienced previous temporary hearing damage (i.e. short-lived tinnitus or hearing loss). Others chose not to use earplugs because music venues are expected to be loud. Peer behaviours and opinions also had a strong influence over earplug use. A lack of knowledge of hearing-related damage resulted in a lack of concern for hearing health and other health conditions taking priority. Conclusions: The challenge is to present hearing health messages that are relevant and accessible to young adults. Music and entertainment venues must also take greater responsibility to protect the hearing of its customers by at least informing visitors of the dangers of loud music.

Background: Exposure to tobacco and alcohol content in audio-visual media is a risk factor for smoking and alcohol use in young people. We report an analysis of tobacco and alcohol content, and estimates of population exposure to this content, in a sample of reality television programmes broadcast in the UK. Methods: We used 1-minute interval coding to quantify tobacco and alcohol content in all episodes of five reality TV programmes aired between January and August 2018 (Celebrity Big Brother; Made in Chelsea; The Only Way is Essex; Geordie Shore and Love Island), and estimated population exposure using viewing data and UK population estimates. Results: We coded 5219 intervals from 112 episodes. Tobacco content appeared in 110 (2%) intervals in 20 (18%) episodes, and alcohol in 2212 (42%) intervals and in all episodes. The programmes delivered approximately 214 million tobacco gross impressions to the UK population, including 47.37 million to children; and for alcohol, 4.9 billion and 580 million respectively. Conclusion: Tobacco, and especially alcohol, content is common in reality TV. The popularity of these programmes with young people, and consequent exposure to tobacco and alcohol imagery, represents a potentially major driver of smoking and alcohol consumption.

This study explored attitudes toward leisure noise, use of hearing protection, and perceived susceptibility to leisure-noise damage in young adults with hearing problems. Twelve participants aged between 18 and 35 years took part in a semistructured interview. Data were analyzed using framework analysis. The results showed that a positive attitude to noise, a passion for loud music, a lack of knowledge of the consequences of noise damage, and perceived low risk of hearing problems were associated with people not using earplugs. The aesthetics, comfort, perceived effects on music quality and attitude of others were all barriers to earplug use. Of those who had used earplugs, previous hearing-related symptoms and concern about future hearing damage were the main motivators for use. Four types of people were identified to describe the variation in attitudes and behaviors: those who had no change in behavior or concern about damage; those who were concerned and used earplugs; those who were concerned and avoided loud venues; and those who were concerned about communication difficulties only. Considering the wide variability, it may be more effective to shift attention from trying to change individual attitudes and behaviors to considering systemic changes to protect hearing, through ensuring the music industry and relevant authorities take greater responsibility.
