Bricolage as an expression of self and of cultural and familial foodways among people living in prison-'You make what you can with anything you can get'.

In this article, we use Lévi-Strauss's (1962, The savage mind, University of Chicago Press) concept of 'bricolage' to explore informal food preparation among men in Scottish prisons. The art of 'making do with whatever is at hand', in innovative and creative ways, to give new functions to everyday items has recently been reimagined and applied to the field of food. It has been used to explore the practice of informal food networks in resource poor environments; investigate how small food businesses come up with new and innovative recipes ideas; and study the way Michelin-starred chefs responded to the COVID-19 pandemic through philanthropic activities. Our aim is to use bricolage as a lens through which to answer questions about whether more autonomy over food might contribute to overall health and wellbeing in prisons. Drawing on in-depth empirical data from qualitative interviews with 20 men in Scottish prisons, we explore how bricolage is used to escape the monotony of prison-issued meals and the tedium of the prison regime; counter threats to self and identity; create and maintain social relationships through joint enterprise and commensality; and create culinary experiences that afford a sense of control and normality in an environment synonymous with 'spoiled identity' (Goffman, 1961, Asylums: Essays on the social situation of mental patients and other inmates, Penguin.).

Evolution of 'whole institution' approaches to improving health in tertiary education settings: a critical scoping review.

In recent decades, 'whole school' approaches to improving health have gained traction, based on settings-based health promotion understandings which view a setting, its actors and processes as an integrated 'whole' system with multiple intervention opportunities. Much less is known about 'whole institution' approaches to improving health in tertiary education settings. We conducted a scoping review to describe both empirical and non-empirical (e.g. websites) publications relating to 'whole settings', 'complex systems' and 'participatory'/'action' approaches to improving the health of students and staff within tertiary education settings. English-language publications were identified by searching five academic and four grey literature databases and via the reference lists of studies read for eligibility. We identified 101 publications with marked UK overrepresentation. Since the 1970s, publications have increased, spanning a gradual shift in focus from 'aspirational' to 'conceptual' to 'evaluative'. Terminology is geographically siloed (e.g., 'healthy university' (UK), 'healthy campus' (USA)). Publications tend to focus on 'health' generally rather than specific health dimensions (e.g. diet). Policies, arguably crucial for cascading systemic change, were not the most frequently implemented intervention elements. We conclude that, despite the field's evolution, key questions (e.g., insights into who needs to do what, with whom, where and when; or efficacy) remain unanswered.

Food and the prison environment: a meta-ethnography of global first-hand experiences of food, meals and eating in custody.

BACKGROUND: Prison foodways offer a unique opportunity to improve the physical and mental health and wellbeing of an underserved population, yet prison food is often rejected in favour of 'junk' food. Improved understanding of the meanings of food in prison is necessary to inform prison food policy and enhance the prison environment. RESULTS: A meta-ethnographic synthesis of 27 papers integrated first-hand experiences of food in prison from 10 different countries. The lived experience for most in custody is of poor-quality prison-issued meals, necessarily consumed at a time and place at odds with socio-cultural norms. Beyond nutrition, food carries clear symbolic meanings in prison; through everyday food activities in prison, especially cooking, empowerment, participation, agency and identity are negotiated and performed. Cooking (with others or alone) can reduce anxiety and depression and increase feelings of self-efficacy and resilience in a socially, psychologically, and financially disadvantaged population. Integrating cooking and sharing food into the routine of prison life strengthens the skills and resources available to prisoners, empowering them as they move from the prison environment to the community. CONCLUSIONS: The potential of food to enhance the prison environment and support improvements in prisoner health and wellbeing is limited when the nutritional content is inadequate and/or where food is served and eaten impacts negatively on human dignity. Prison policy which provides opportunities for cooking and sharing food that better reflects familial and cultural identity has the potential to improve relationships, increase self-esteem, build and maintain life skills needed for reintegration.

A Qualitative Study on Young Men's Experiences of Intentional Weight-Gain.

This qualitative study investigated how young men perceive their body image and experiences of purposively gaining weight, and what these reveal about broader sociocultural meanings around food, consumption and male body image. The participants in this study were a subsample of men participating in the 'GlasVEGAS' study which examined the effect of weight-gain and weight loss on metabolism, fitness and disease risk in young adult men. Twenty-three qualitative, semi-structured interviews were conducted with thirteen men (mean age 23 years) at GlasVEGAS baseline (n = 10) and weight-gain (6-week) follow-up assessment (n = 13). Data were analysed using the principles of framework analysis. The majority of men viewed the foods provided as part of the GlasVEGAS study as 'luxury' items despite their being of low nutritional value. The weight-gain process prompted men to reflect on how cultural norms and social environments may amplify overeating. Several described being surprised at how quickly they assimilated unhealthy eating habits and/or gained weight. Some valued changes in their appearance associated with weight-gain, including appearing larger or having increased muscle size. These factors are vital to consider when developing weight management initiatives targeting young men, including the valorisation of unhealthy foods, wider social influences on diet and male body image ideals.

Implementation of a national smoke-free prison policy: an economic evaluation within the Tobacco in Prisons (TIPs) study.

OBJECTIVE: To determine the cost-effectiveness of a smoke-free prison policy in Scotland, through assessments of the trade-offs between costs (healthcare and non-healthcare-related expenditure) and outcomes (health and non-health-related non-monetary consequences) of implementing the policy. DESIGN: A health economic evaluation consisting of three analyses (cost-consequence, cost-effectiveness and cost-utility), from the perspectives of the healthcare payer, prison service, people in custody and operational staff, assessed the trade-offs between costs and outcomes. Costs associated with the implementation of the policy, healthcare resource use and personal spend on nicotine products were considered, alongside health and non-health outcomes. The cost-effectiveness of the policy was evaluated over 12-month and lifetime horizons (short term and long term). SETTING: Scotland's national prison estate. PARTICIPANTS: People in custody and operational prison staff. INTERVENTION: Implementation of a comprehensive (indoor and outdoor) smoke-free policy. MAIN OUTCOME MEASURES: Concentration of secondhand smoke, health-related quality of life (health utilities and quality-adjusted life-years (QALY)) and various non-health outcomes (eg, incidents of assaults and fires). RESULTS: The short-term analyses suggest cost savings for people in custody and staff, improvements in concentration of secondhand smoke, with no consistent direction of change across other outcomes. The long-term analysis demonstrated that implementing smoke-free policy was cost-effective over a lifetime for people in custody and staff, with approximate cost savings of £28 000 and £450, respectively, and improvement in health-related quality of life of 0.971 QALYs and 0.262, respectively. CONCLUSION: Implementing a smoke-free prison policy is cost-effective over the short term and long term for people in custody and staff.

Challenges associated with e-cigarette use by people in custody in Scottish prisons: a qualitative interview study with prison staff.

OBJECTIVES: Little is known about the perspectives of staff working in prisons where e-cigarettes are permitted. Scotland now permits people in custody (PiC), but not staff/visitors to use e-cigarettes, following implementation of smoke-free prisons policy in 2018. Previous studies, conducted before and immediately after the introduction of e-cigarettes in Scottish prisons, have evidenced stakeholder support for their use by PiC. This study focuses on key challenges associated with e-cigarette use in prisons, using data collected from prison staff once e-cigarettes had been allowed in a smoke-free environment for 6-9 months. SETTING: Five prisons in Scotland. PARTICIPANTS: Sixteen qualitative interviews were conducted with prison staff from five prisons varying by population (sex, age and sentence length). Data were managed and analysed using the framework approach. RESULTS: While these staff confirmed strong support for the smoke-free prison policy and reported some benefits of replacing tobacco with e-cigarettes, they also spoke of the challenges e-cigarettes pose. These included: workplace e-cigarette vapour exposures; perceptions that e-cigarettes provide a new, effective way for some PiC to take illegal drugs, particularly new psychoactive substances; organisational challenges relating to the value attached to e-cigarettes in prisons; and implications for long-term nicotine use and tobacco cessation. Staff anticipated difficulties in tightening restrictions on e-cigarette use by PiC given its scale and significance among this population. CONCLUSIONS: Maximising the benefits of e-cigarette use by PiC is likely to require multiple measures to support effective and safe use and e-cigarette reduction/cessation where desired. This includes monitoring any misuse of e-cigarettes, and provision of guidance and support on appropriate e-cigarette use and how to limit or quit use if desired. Findings are relevant to jurisdictions considering or planning changes in prison smoking or vaping policies.

Sexual harassment in secondary school: Prevalence and ambiguities. A mixed methods study in Scottish schools.

BACKGROUND: Adolescence is characterized by identity formation, exploration and initiation of intimate relationships. Much of this occurs at school, making schools key sites of sexual harassment. Schools often lack awareness and understanding of the issue, and UK research on the topic is scarce. We explored prevalence and perceptions of sexual harassment in a school-based mixed-methods study of 13-17 year-old Scottish adolescents. METHODS: A student survey (N = 638) assessed past 3-months school-based victimization and perpetration prevalence via 17 behavioral items based on the most commonly used school-based sexual harassment measure ('Hostile Hallways'). Eighteen focus groups (N = 119 students) explored which of 10 behaviors were perceived as harassing/unacceptable and why. RESULTS: Two-thirds reported any victimization: 64.7% 'visual/verbal' (e.g. sexual jokes) and 34.3% 'contact/personally-invasive' behaviors (e.g. sexual touching; most of whom also reported experiencing visual/verbal types) in the past 3-months. Data suggested a gateway effect, such that contact/personally-invasive behaviors are more likely to be reported by those also reporting more common visual/verbal behaviors. Some survey participants reported being unsure about whether they had experienced certain behaviors; and in focus groups, participants expressed uncertainty regarding the acceptability of most behaviors. Ambiguities centered on behavioral context and enactment including: degree of pressure, persistence and physicality; degree of familiarity between the instigator-recipient; and perception of the instigator's intent. In attempting to resolve ambiguities, students applied normative schemas underpinned by rights (to dignity, respect and equality) and 'knowingness', usually engendered by friendship. CONCLUSIONS: Our study confirms school-based sexual harassment is common but also finds significant nuance in the ways in which students distinguish between acceptable and harassing. School-based strategies to tackle sexual harassment must engage with this complexity.

School Climate, Peer Relationships, and Adolescent Mental Health: A Social Ecological Perspective.

The current study investigated peer relationship and school climate factors associated with adolescent mental health. Cross-sectional data from 2,571 fifteen-year old students in 22 Scottish secondary schools was used. Multilevel models tested for school differences in mental health, and nested linear regression models estimated peer and school effects. Results demonstrated no significant between-school variation in mental health. Peer victimization was the only peer effect associated with mental health. School-belonging, student-teacher relationships, and a perceived inclusive school climate were associated with better mental health, whereas a perceived school climate of exam pressure was associated with worse mental health. The findings highlight multiple aspects of school climate that could be targeted in school-based interventions for adolescent mental health.

Evaluation of a national smoke-free prisons policy using medication dispensing: an interrupted time-series analysis.

BACKGROUND: Internationally, smoking prevalence among people in prison custody (ie, people on remand awaiting trial, awaiting sentencing, or serving a custodial sentence) is high. In Scotland, all prisons implemented a comprehensive smoke-free policy in 2018 after a 16-month anticipatory period. In this study, we aimed to use data on medication dispensing to assess the impact of this policy on cessation support, health outcomes, and potential unintended consequences among people in prison custody. METHODS: We did an interrupted time-series analysis using dispensing data for 44 660 individuals incarcerated in 14 closed prisons in Scotland between March 30, 2014, and Nov 30, 2019. We estimated changes in dispensing rates associated with the policy announcement (July 17, 2017) and full implementation (Nov 30, 2018) using seasonal autoregressive integrated moving average models. Medication categories of primary interest were treatments for nicotine dependence (as an indicator of smoking cessation or abstinence attempts), acute smoking-associated illnesses, and mental health (antidepressants). We included antiepileptic medications as a negative control. FINDINGS: A 44% step increase in dispensing of treatments for nicotine dependence was observed at implementation (2250 items per 1000 people in custody per fortnight, 95% CI 1875 to 2624) due primarily to a 42% increase in dispensing of nicotine replacement therapy (2109 items per 1000 people in custody per fortnight, 1701 to 2516). A 9% step decrease in dispensing for smoking-related illnesses was observed at implementation, largely accounted for by respiratory medications (-646 items per 1000 people in custody per fortnight, -1111 to -181). No changes associated with announcement or implementation were observed for mental health dispensing or antiepileptic medications (control). INTERPRETATION: Smoke-free prison policies might improve respiratory health among people in custody and encourage smoking abstinence or cessation without apparent short-term adverse effects on mental health dispensing.

Initial Views and Experiences of Vaping in Prisons: A Qualitative Study With People in Custody Preparing for the Imminent Implementation of Scotland's Prison Smokefree Policy.

INTRODUCTION: Scotland is one of the few countries in which e-cigarettes were available in prisons before the introduction of a comprehensive national smokefree policy, to assist in its implementation. This qualitative study explores the initial views and experiences of vaping in this specific context, from the perspective of people in custody (prisoners). AIMS AND METHODS: Twenty-eight people in custody were interviewed approximately 1-2 months after rechargeable e-cigarettes were made available in prisons and 2-5 weeks before implementation of a smokefree policy. Data were thematically analyzed to identify the range and diversity of views and experiences. RESULTS: Participants expressed support for e-cigarettes in preparation for the smokefree policy, describing their symbolic and practical value in this context. Uptake of vaping was strongly influenced by the need for participants to manage without tobacco in the near future. Participants evaluated their initial vaping experiences, either positively or negatively, in relation to the utility of e-cigarettes for mandated smoking abstinence and in providing satisfaction, pleasure, and novelty. Participant views on several issues related to e-cigarette use, both specific to the prison population (product choice and cost) and more generally (safety and long-term use), are explored. CONCLUSIONS: Our findings suggest possible benefits of e-cigarettes as one means of supporting smokefree policy in a population with many smokers. They also point to potential challenges posed by vaping in prisons and smokefree settings caring for similar populations. There is a need for ongoing measures to maximize the health benefits of smokefree settings and for further research on vaping in situations of enforced abstinence. IMPLICATIONS: To our knowledge, no published studies have explored views and experiences of vaping in prison, when rechargeable vapes were new and the removal of tobacco was imminent. The results can inform tobacco control policy choices, planning and implementation in prisons and similar settings. In prison systems that permitting vaping, it is important that other measures (eg, information campaigns and nicotine dependence services) are implemented concurrently to minimize potential risks to the health or personal finances of people in custody.

E-cigarette Use in Prisons With Recently Established Smokefree Policies: A Qualitative Interview Study With People in Custody in Scotland.

INTRODUCTION: E-cigarettes were one measure introduced to help people in custody (PiC) to prepare for and cope with implementation of comprehensive smokefree policies in Scottish prisons. Our earlier study explored experiences of vaping when e-cigarettes were first introduced and most participants were dual tobacco and e-cigarette users. Here we present findings of a subsequent study of vaping among a different sample of PiC when use of tobacco was prohibited in prison, and smokefree policy had become the norm. METHODS: Twenty-eight qualitative interviews were conducted with PiC who were current or former users of e-cigarettes in prison, 6-10 months after implementation of a smokefree policy. Data were managed and analyzed using the framework approach. RESULTS: PiC reported that vaping helped with mandated smoking abstinence. However, findings suggest that some PiC may be susceptible to heavy e-cigarette use potentially as a consequence of high nicotine dependence and situational factors such as e-cigarette product choice and availability in prisons; issues with nicotine delivery; prison regimes; and use of e-cigarettes for managing negative emotions. These factors may act as barriers to cutting down or stopping use of e-cigarettes by PiC who want to make changes due to dissatisfaction with vaping or lack of interest in continued use of nicotine, cost, and/or health concerns. CONCLUSIONS: E-cigarettes helped PiC to cope with smokefree rules, although concerns about e-cigarette efficacy, cost, and safety were raised. PiC may desire or benefit both from conventional smoking cessation programs and from interventions to support reduction, or cessation, of vaping. IMPLICATIONS: Findings highlight successes, challenges, and potential solutions in respect of use of e-cigarettes to cope with mandated smoking abstinence in populations with high smoking prevalence and heavy nicotine dependence. Experiences from prisons in Scotland may be of particular interest to health and/or justice services in other jurisdictions, with similar legislation on e-cigarettes to the United Kingdom, who are planning for institutional smokefree policies in their prisons or inpatient mental health settings in the future.

From Smoking-Permitted to Smokefree Prisons: A 3-Year Evaluation of the Changes in Occupational Exposure to Second-Hand Smoke Across a National Prison System.

OBJECTIVES: Prisons in Scotland were one of the few workplaces exempt from the 2006 comprehensive smoking ban in indoor public places, excluding the prison workforce from the health benefits of smokefree workplaces. The November 2018 introduction of comprehensive restrictions on smoking in Scottish prisons aimed to protect prison staff and people in custody from the harmful impacts of second-hand smoke (SHS) exposure. This study presents SHS exposure data gathered after smokefree policy implementation and compares these with data gathered during and before policy development. METHODS: Dylos DC1700 monitors were used to measure concentrations of fine particulate matter (PM2.5) derived from SHS across Scotland's 15 prisons. Six days of fixed-site monitoring (09.00 22 May 2019 to 09.00 28 May 2019) were conducted in residential halls in each prison 6 months post-smokefree policy implementation. Prison staff task-based measurements were conducted to assess concentrations of SHS in various locations (e.g. gyms and workshops) and during specific activities (e.g. cell searches, maintenance, and meal service). Utilizing the fixed-site monitoring data, typical daily PM2.5 exposure profiles were constructed for the prison service and time-weighted average (TWA) exposure concentrations were estimated for the typical shift patterns of residential staff pre- and post-smokefree policy implementation. Staff perceptions of changes to SHS exposure were assessed using online surveys. RESULTS: Analysis of both fixed-site and mobile task-based PM2.5 measurements showed the smokefree policy implementation was successful in reducing SHS exposures across the Scottish prison estate. Measured PM2.5 in residential halls declined markedly; median fixed-site concentrations reduced by more than 91% compared with measures in 2016 before policy announcement. The changes in the TWA concentrations across shifts (over 90% decrease across all shifts) and task-based measurements (89% average decrease for high-exposure tasks) provide evidence that prison staff exposure to SHS has significantly reduced. Following smokefree policy implementation, the majority of staff reported no longer being exposed to SHS at work. CONCLUSIONS: To our knowledge, this is the first comprehensive international study to objectively measure SHS levels before, during, and after implementation of a smokefree policy across a country's prison system. The findings confirm that such a policy change can be successfully implemented to eliminate occupational exposures to SHS. The results are highly relevant for other jurisdictions considering changes to prison smoking legislation.

Youth vaping and smoking and parental vaping: a panel survey.

BACKGROUND: Concerns remain about potential negative impacts of e-cigarettes including possibilities that: youth e-cigarette use (vaping) increases risk of youth smoking; and vaping by parents may have impacts on their children's vaping and smoking behaviour. METHODS: With panel data from 3291 youth aged 10-15 years from the 7th wave of the UK Understanding Society Survey (2015-2017), we estimated effects of youth vaping on youth smoking (ever, current and past year initiation), and of parental vaping on youth smoking and vaping, and examined whether the latter differed by parental smoking status. Propensity weighting was used to adjust for measured confounders and estimate average effects of vaping for all youth, and among youth who vaped. E-values were calculated to assess the strength of unmeasured confounding influences needed to negate our estimates. RESULTS: Associations between youth vaping and youth smoking were attenuated considerably by adjustment for measured confounders. Estimated average effects of youth vaping on youth smoking were stronger for all youth (e.g. OR for smoking initiation: 32.5; 95% CI: 9.8-107.1) than among youth who vaped (OR: 4.4; 0.6-30.9). Relatively strong unmeasured confounding would be needed to explain these effects. Associations between parental vaping and youth vaping were explained by measured confounders. Estimates indicated effects of parental vaping on youth smoking, especially for youth with ex-smoking parents (e.g. OR for smoking initiation: 11.3; 2.7-46.4) rather than youth with currently smoking parents (OR: 1.0; 0.2-6.4), but these could be explained by relatively weak unmeasured confounding. CONCLUSIONS: While measured confounding accounted for much of the associations between youth vaping and youth smoking, indicating support for underlying propensities, our estimates suggested residual effects that could only be explained away by considerable unmeasured confounding or by smoking leading to vaping. Estimated effects of youth vaping on youth smoking were stronger among the general youth population than among the small group of youth who actually vaped. Associations of parental vaping with youth smoking and vaping were either explained by measured confounding or could be relatively easily explained by unmeasured confounding.

Mental health disorders and adolescent peer relationships.

RATIONALE: Mental health disorders often arise during adolescence, with disruptive behavior disorders and anxiety disorders among the most common. Given the salience of peer relationships during adolescence, and research suggesting that mental health disorders negatively impact social functioning, this study uses novel methodology from social network analysis to uncover the social processes linking disruptive behavior disorders and anxiety disorders with adolescent friendships. In particular, the study focuses on peer withdrawal, peer popularity, and peer homophily in relation to both disorders. METHODS: Data come from 15-year old students in four Scottish secondary schools (N = 602). Diagnoses of disruptive behavior disorders and anxiety disorders were produced using the Diagnostic Interview Schedule for Children, and peer relationship data were obtained through a friendship nomination survey. Exponential random graph models were used to estimate the probability of peer withdrawal, peer popularity, and peer homophily based on each disorder. RESULTS: Results demonstrated that adolescents with disruptive behavior disorders were more popular than their peers without disruptive behavior disorders (OR: 1.47, CI: 1.20, 1.87). Friendship was also more likely between two adolescents both with or both without disruptive behavior disorders (OR: 1.26, CI: 1.07, 1.47), demonstrating peer homophily. There was no evidence that anxiety disorders were related to adolescent peer relationships. CONCLUSIONS: Findings from this study suggest that disruptive behavior disorders may be socially rewarded (e.g., peer popularity) and socially clustered (e.g., homophily), whereas anxiety disorders show no such trends. Thus, intervention efforts must account for the peer social status that may be gained from engaging in disruptive behavior during this developmental period. Further, given that similarity in DBD status is associated with an increased likelihood of friendship, adolescents are likely to be surrounded by peers who reinforce their behaviors.

How men receive and utilise partner support when trying to change their diet and physical activity within a men's weight management programme.

BACKGROUND: The impacts of interventions designed to change health behaviours are potentially affected by the complex social systems in which they are embedded. This study uses Scottish data to explore how men receive and utilise partner support when attempting to change dietary practices and physical activity within the context of Football Fans in Training (FFIT), a gender-sensitised weight management and healthy living programme for men who are overweight/obese. METHODS: Separate semi-structured face-to-face interviews were conducted with 20 men and their cohabiting female partners (total n = 40), 3-12 months after the men had completed FFIT. Data were thematically analysed and individual interviews were combined for dyadic analysis. RESULTS: Men's and women's accounts suggested variations in men's need for, and utilisation of, partner support in order to make changes to dietary practices and physical activity. There were also differences in descriptions of women's involvement in men's behaviour changes. Typologies were developed categorising men as 'resolute', 'reliant'/'receptive' and 'non-responsive' and women as 'very involved', 'partially involved' and 'not involved'. Men were more reliant, and women more involved, in changes to dietary practices compared to physical activity. The role of partner involvement in promoting men's behaviour change seemed contingent on men's resoluteness, or their reliance on the partner support. CONCLUSIONS: These results highlight how interactions between men's resoluteness/reliance on cohabiting female partners and the partners' involvement impact the extent to which female partners influence men's changes to dietary practices and physical activity following a weight loss intervention. Understanding this interaction could increase the impact of health interventions aimed at one individual's behaviour by considering other family members' roles in facilitating those changes. The typologies developed for this study might contribute towards the development of behaviour change theories within the cohabiting couple context.

Socioeconomic patterning of vaping by smoking status among UK adults and youth.

BACKGROUND: Smoking contributes significantly to socioeconomic health inequalities. Vaping has captured much interest as a less harmful alternative to smoking, but may be harmful relative to non-smoking. Examining inequalities in vaping by smoking status, may offer insights into potential impacts of vaping on socioeconomic inequalities in health. METHODS: Data were from 3291 youth (aged 10-15) and 35,367 adults (aged 16+) from wave 7 (2015-17) of the UK Household Longitudinal Study. In order to adjust for biases that could be introduced by stratifying on smoking status, marginal structural models were used to estimate controlled direct effects of an index of socioeconomic disadvantage (incorporating household education, occupation and income) on vaping by smoking status (among adults and youth), adjusting for relevant confounders and for selection into smoking states. We also estimated controlled direct effects of socioeconomic disadvantage on being an ex-smoker by vaping status (among adult ever-smokers; n = 18,128). RESULTS: Socioeconomic disadvantage was associated with vaping among never smoking youth (OR for a unit increase in the socioeconomic index: 1.17; 95%: 1.03-1.34), and among ex-smoking adults (OR: 1.17; 95% CI: 1.09-1.26), with little to no association among never smoking (OR: 0.98; 95% CI: 0.91-1.07) and current smoking (OR: 1.00; 95% CI: 0.93-1.07) adults. Socioeconomic disadvantage was also associated with reduced odds of being an ex-smoker among adult ever-smokers, but this association was moderately weaker among those who vaped (OR: 0.88; 95% CI: 0.82-0.95) than those who did not (OR: 0.82; 95% CI: 0.80-0.84; p-value for difference = 0.081). CONCLUSIONS: Inequalities in vaping among never smoking youth and adult ex-smokers, suggest potential to widen health inequalities, while weaker inequalities in smoking cessation among adult vapers indicate e-cigarettes could help narrow inequalities. Further research is needed to understand the balance of these opposing potential impacts, and how any benefits can be maximised whilst protecting the vulnerable.

The impact of implementation of a national smoke-free prisons policy on indoor air quality: results from the Tobacco in Prisons study.

OBJECTIVE: To determine secondhand smoke (SHS) concentrations in prisons during the week of implementation of a new, national prisons smoke-free policy. DESIGN: Repeated measurement of SHS concentrations immediately before and after implementation of smoke-free policies across all 15 prisons in Scotland, and comparison with previously gathered baseline data from 2016. METHODS: Fine particulate matter (PM2.5) measurements at a fixed location over a continuous 6-day period were undertaken at the same site in each prison as previously carried out in 2016. Outdoor air quality data from the nearest local authority measurement station were acquired to determine the contribution of outdoor air pollution to indoor prison measurement of PM2.5. RESULTS: Air quality improved in all prisons comparing 2016 data with the first full working day postimplementation (overall median reduction -81%, IQR -76% to -91%). Postimplementation indoor PM2.5 concentrations were broadly comparable with outdoor concentrations suggesting minimal smoking activity during the period of measurement. CONCLUSIONS: This is the first evaluation of changes in SHS concentrations across all prisons within a country that has introduced nationwide prohibition of smoking in prisons. All prisons demonstrated immediate substantial reductions in PM2.5 following policy implementation. A smoke-free prisons policy reduces the exposure of prison staff and prisoners to SHS.

Predictors of opinions on prison smoking bans: Analyses of survey data from Scottish staff and prisoners.

INTRODUCTION: Policy-makers and practitioners need to understand characteristics associated with support for smoking restrictions to identify both potential allies and groups requiring particular support/targeted communication in the face of restrictions. Using data from prison staff and prisoners, we explored the structure and correlates of opinions relating to prison smoking bans. METHODS: Questionnaires were completed by staff (online, N=1271; 27% return) and prisoners (paper-based, N=2512; 34%) in all 15 Scottish prisons in 2016-17. At that time, prisoners could smoke in their own cells and during outdoor recreation; staff smoking was prohibited anywhere on prison grounds. Staff and prisoner questionnaires included identical/very similar questions about opinions on smoking in prisons and prison smoking bans, own smoking behaviour, health and sociodemographic details. We also measured in every prison fine particulate matter (PM2.5) as a proxy for secondhand smoke (SHS) levels. RESULTS: Principal components analysis identified two factors: 'Positive about bans' (higher scores among staff) and 'Bans will be difficult' (higher scores among prisoners). In multivariable analyses, 'Positive about bans' was associated with: not smoking (both staff and prisoners), better general health, more respiratory symptoms and working in an operational role among staff; and no asthma, more sensory symptoms, higher educational level and status/release date among prisoners. 'Bans will be difficult' was associated with: fewer sensory symptoms and lower prison SHS levels among staff and being a smoker among prisoners. In smoker-only analyses, heavier smokers were less positive about bans and more likely to believe bans will be difficult. CONCLUSIONS: Results suggest it is possible to be positive about prison smoking bans whilst also recognising and/or concerned about potential operational difficulties, and that these opinions are associated with several characteristics additional to smoker status. Support for future prison bans may be stronger if staff have access to objective SHS exposure measures.

Views of prison staff in Scotland on the potential benefits and risks of e-cigarettes in smoke-free prisons: a qualitative focus group study.

OBJECTIVE: Electronic cigarettes (e-cigarettes) were introduced into all Scottish prisons in February 2018, some months after prisons began preparing in 2017 for a smoking ban implemented in November 2018. In 2016/2017, prison staff views on the potential benefits and risks of e-cigarettes were explored in advance of the introduction of: (1) a smoking ban and (2) e-cigarettes. SETTING: Fourteen prisons in Scotland. PARTICIPANTS: Seventeen focus groups and two paired interviews were conducted with 132 staff in 14 Scottish prisons 4-9 months before plans for a smoking ban were announced in July 2017. Both smoking and non-smoking staff were invited to participate. RESULTS: Prison staff highlighted three potential risks of e-cigarettes in smoke-free prisons: staff health risks from e-cigarette vapour; prisoner health risks from vaping; and risks to both groups from e-cigarette misuse, defects or accidents. Conversely, potential benefits of e-cigarettes in smoke-free prisons centred on: reducing smoking-related health harms to staff and prisoners; helping prisoners to manage without tobacco; and supporting staff to maintain safety and discipline in prison. Staff who participated in focus groups had limited experience of vaping and expressed some uncertainty and misunderstandings about e-cigarettes. CONCLUSION: Our findings highlight that scientific uncertainty, misunderstanding about vaping, the complexity of prisons as workplaces and prison tobacco control policy all have implications for staff perceptions of the potential place of e-cigarettes in smoke-free prisons. To alleviate staff concerns, there is a need for reliable information on e-cigarettes. Staff may also require reassurances on whether products are 'tamper proof', and rules about vaping indoors.
