Implementation and impact of anti-smoking interventions in three prisons in the absence of appropriate legislation

Réduire le tabagisme dans les prisons : éléments théoriques et méthodologiques nécessaires à la co-construction d’une intervention en contexte pénitentiaire

Révélateur des inégalités sociales de santé, le tabagisme en établissement pénitentiaire exige des interventions visant sa réduction d’être adaptées aux spécificités du milieu carcéral. Dans le cadre de la recherche interventionnelle TABAPRI, nous avons mobilisé une première étude sociologique afin d’apporter des connaissances sur cette problématique. Une enquête a été réalisée au sein de trois établissements pénitentiaires, précédant les phases de construction, d’implémentation et d’évaluation de l’intervention. Cet article décrit d’une part la démarche méthodologique et d’autre part, la contribution de la sociologie, tant dans ses apports conceptuels que méthodologiques, à la construction d’une intervention. Notre travail a notamment souligné l’importance d’aménager des espaces d’échange permettant aux professionnels et aux personnes détenues de construire ensemble les modalités d'intervention qui participent à la réduction du tabagisme en détention.

How did the tobacco ban increase inmates' body weight during incarceration in Canadian federal penitentiaries? A cohort study

OBJECTIVE

This study aimed to determine how inmates' body weight changed during incarceration in Canadian federal penitentiaries, based on their history of tobacco use. Since tobacco was banned from all Canadian federal penitentiaries in 2008, little is known about the unintended health consequences of this ban, especially on inmates' body weight.

DESIGN

Cohort study.

SETTING

Participants were male and female inmates incarcerated for at least 6 months in Canadian federal penitentiaries. We collected data from 10 institutions in two Canadian regions (Ontario and Atlantic).

PARTICIPANTS

We collected data from 754 inmates who volunteered to participate in the study.

INTERVENTION

This study examined weight change in relation to a history of tobacco use. In 2016-2017, anthropometric data were collected and compared with recorded anthropometric data at the beginning of incarceration (mean follow-up of 5.0±8.3 years). Self-reported data on tobacco and substance use were collected. Weight change was compared between inmates with and without a history of tobacco use.

OUTCOMES

The main outcome measures were body weight change (kg), body mass index (BMI) change (kg/m²), annual weight change (kg/year), and BMI and waist circumference (cm) at the time of the interview.

RESULTS

During incarceration, ex-smokers gained more than twice the amount of weight compared with non-smokers (7.5 kg weight gain for smokers vs 3.7 kg weight gain for non-smokers). Once adjusted for covariates in a regression analysis, for inmates who gained the most weight (75th and 90th percentiles), non-smokers had, respectively, 1.64 and 2.3 lower BMI points than ex-smokers.

CONCLUSIONS

During incarceration in Canadian federal penitentiaries, inmates with a history of tobacco use gained significantly more weight than non-smokers. This put them at increased risk of developing obesity-related health problems. This information is important for the prison setting when planning related programmes and regulation.

Smoking in Correctional Settings Worldwide: Prevalence, Bans, and Interventions

Smoking tobacco contributes to 11.5% of deaths worldwide and, in some countries, more hospitalizations than alcohol and drugs combined. Globally in 2015, 25% of men and 5% of women smoked. In the United States, a higher proportion of people in prison smoke than do community-dwelling individuals. To determine smoking prevalence in prisons worldwide, we systematically reviewed the literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines; we also examined whether prisons banned smoking or treated smokers. We searched databases for articles published between 2012 and 2016 and located 85 relevant articles with data representing 73.5% of all incarcerated persons from 50 countries. In 35 of 36 nations (97%) with published prevalence data, smoking for the incarcerated exceeded community rates 1.04- to 62.6-fold. Taking a conservative estimate of a 2-fold increase, we estimated that, globally, 14.5 million male and 26,000 female smokers pass through prisons annually. Prison authorities’ responses include permitting, prohibiting, or treating tobacco use. Bans may temporarily improve health and reduce in-prison health care costs but have negligible effect after prison release. Evidence-based interventions for smoking cessation effective outside prisons are effective inside; effects persist after release. Because smoking prevalence is heightened in prisons, offering evidence-based interventions to nearly 15 million smokers passing through yearly would improve global health.

Systematic review of health and behavioural outcomes of smoking cessation interventions in prisons

Objective

We conducted a systematic review to examine the impact of smoking cessation interventions, including smoking bans, on prisoners and prison staff.

Data sources

We systematically searched health and criminal justice databases for relevant studies. Search strings were used to combine terms related to smoking cessation interventions with terms related to incarceration. We used forward and backward snowballing to capture additional studies.

Study selection

Studies were included if: they were published between 1 January 1994 and 23 May 2016; the population was incarcerated adults and/or prison staff; they had a quantitative component; they were published in English; and they reported outcomes of a smoking cessation programme/ban with regard to reported change in smoking behaviour and/or behavioural outcomes.

Data extraction

Studies were reviewed for methodological rigour using the Effective Public Health Practice Project's Quality Assessment Tool for Quantitative Studies. Data were independently reviewed for methodological quality by 1 author and a research assistant.

Data synthesis

Cessation programmes, including free nicotine replacement therapy and/or behavioural counselling can significantly increase the likelihood of quitting in prison and increase abstinence postrelease. Indoor bans have little impact on prisoner smoking behaviour. Prisoners who experience a complete smoking ban typically resume smoking shortly after release from prison. Bans may result in adverse behavioural outcomes, but these are generally minimal and short-lived.

Conclusions

While there is limited evidence to inform tobacco control policies in custodial settings, outcomes of this review suggest that cessation programmes/bans can be an effective mechanism to interrupt prisoner smoking behaviour when properly enforced.

Impact of institutional smoking bans on reducing harms and secondhand smoke exposure

BACKGROUND

Smoking bans or restrictions can assist in eliminating nonsmokers' exposure to the dangers of secondhand smoke and can reduce tobacco consumption amongst smokers themselves. Evidence exists identifying the impact of tobacco control regulations and interventions implemented in general workplaces and at an individual level. However, it is important that we also review the evidence for smoking bans at a meso- or organisational level, to identify their impact on reducing the burden of exposure to tobacco smoke. Our review assesses evidence for meso- or organisational-level tobacco control bans or policies in a number of specialist settings, including public healthcare facilities, higher education and correctional facilities.

OBJECTIVES

To assess the extent to which institutional smoking bans may reduce passive smoke exposure and active smoking, and affect other health-related outcomes.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE, EMBASE, and the reference lists of identified studies. We contacted authors to identify completed or ongoing studies eligible for inclusion in this review. We also checked websites of state agencies and organisations, such as trial registries. Date of latest searches was 22nd June 2015.

SELECTION CRITERIA

We considered studies that reported the effects of tobacco bans or policies, whether complete or partial, on reducing secondhand smoke exposure, tobacco consumption, smoking prevalence and other health outcomes, in public healthcare, higher educational and correctional facilities, from 2005 onwards.The minimum standard for inclusion was having a settings-level policy or ban implemented in the study, and a minimum of six months follow-up for measures of smoking behaviour. We included quasi-experimental studies (i.e. controlled before-and-after studies), interrupted time series as defined by the Cochrane Effective Practice and Organization of Care Group, and uncontrolled pre- and post-ban data.

DATA COLLECTION AND ANALYSIS

Two or more review authors independently assessed studies for inclusion in the review. Due to variation in the measurement of outcomes we did not conduct a meta-analysis for all of the studies included in this review, but carried out a Mantel-Haenszel fixed-effect meta-analysis, pooling 11 of the included studies. We evaluated all studies using a qualitative narrative synthesis.

MAIN RESULTS

We included 17 observational studies in this review. We found no randomized controlled trials. Twelve studies are based in hospitals, three in prisons and two in universities. Three studies used a controlled before-and-after design, with another site used for comparison. The remaining 14 studies used an uncontrolled before-and-after study design. Five studies reported evidence from two participant groups, including staff and either patients or prisoners (depending on specialist setting), with the 12 remaining studies investigating only one participant group.The four studies (two in prisons, two in hospitals) providing health outcomes data reported an effect of reduced secondhand smoke exposure and reduced mortality associated with smoking-related illnesses. No studies included in the review measured cotinine levels to validate secondhand smoke exposure. Eleven studies reporting active smoking rates with 12,485 participants available for pooling, but with substantial evidence of statistical heterogeneity (I² = 72%). Heterogeneity was lower in subgroups defined by setting, and provided evidence for an effect of tobacco bans on reducing active smoking rates. An analysis exploring heterogeneity within hospital settings showed evidence of an effect on reducing active smoking rates in both staff (risk ratio (RR) 0.71, 95% confidence interval ( CI) 0.64 to 0.78) and patients (RR 0.86, 95% CI 0.76 to 0.98), but heterogeneity remained in the staff subgroup (I² = 76%). In prisons, despite evidence of reduced mortality associated with smoking-related illnesses in two studies, there was no evidence of effect on active smoking rates (1 study, RR 0.99, 95% CI 0.84 to 1.16).We judged the quality of the evidence to be low, using the GRADE approach, as the included studies are all observational.

AUTHORS' CONCLUSIONS

We found evidence of an effect of settings-based smoking policies on reducing smoking rates in hospitals and universities. In prisons, reduced mortality rates and reduced exposure to secondhand smoke were reported. However, we rated the evidence base as low quality. We therefore need more robust studies assessing the evidence for smoking bans and policies in these important specialist settings.

Smoking cessation in male prisoners: a literature review

PURPOSE

The purpose of this paper is to review the available literature relating to smoking cessation (SC) for the male prisoner population.

DESIGN/METHODOLOGY/APPROACH

Databases PubMed, CINAHL and MEDLINE were searched for English language studies from 1990 to 2012. The authors identified 12 papers examining SC in male prisoners. Full-text articles were analysed for inclusion.

FINDINGS

A total of 12 studies were identified for inclusion. Four studies focused on forced abstinence (a smoking ban) while the remainder looked at various combinations of nicotine replacement, pharmacology and behavioural techniques. No robust studies were found that examined nursing approaches to SC for the prisoner population. The evidence shows a strong "pro-smoking" culture in prison and that many prisoners continue to smoke irrespective of an enforced ban. However, SC strategies can be successful if implemented systematically and supported by consistent policies.

RESEARCH LIMITATIONS/IMPLICATIONS

Female-only prisoner studies were excluded as females comprise just 7 per cent of the Australian prisoner population. The analysis does not differentiate between maximum- or minimum-security prisons, or length of prison sentence. Results cannot be generalised to other forms of detention such as police custody or immigration detention centres. Studies were not appraised for quality, as exclusion on that basis would render further exploration untenable. The analysis was presented in a narrative rather than meta-analytical format and may be subject to interpretation.

PRACTICAL IMPLICATIONS

This paper provides a foundation on which to build further research evidence into the smoking behaviour of prisoners. This information can be used to advocate for healthier public policy for a vulnerable and marginalised population.

ORIGINALITY/VALUE

To the authors' knowledge, this is the first literature review into SC interventions in prisons. The authors apply the findings of this literature review to the five strategies for health promotion to propose a population approach to smoking cessation in male prisoners. Recommendations specific to the correctional environment are outlined for consideration by correctional health professionals.

Tobacco use among prison staff in Germany: a cross-sectional study

BACKGROUND

Studies on tobacco in the prison environment report high prevalence of use among detainees, but little data regarding staff are available. An observational study addressing tobacco control in German prisons was conducted in 2011. It involved multiple strands (quantitative and qualitative components) both among detainees and staff. This article presents quantitative results regarding staff.

METHODS

Cross-sectional study among prison employees in 16 different institutions in nine regions (Länder) in Germany. Tobacco use and second-hand smoke (SHS) exposure (primary outcomes) were assessed by a questionnaire designed specifically. Logistic regression models were used to assess the risk factors associated with each outcome.

RESULTS

Among 704 participants (60.6% male, mean age 43.9 years ± 9.33), 27.7% are smokers and 68% declared to be exposed to SHS. Independent factors associated with smoking were female gender [odds ratio (OR) 1.49,P= 0.026], an age below 45 years (OR 1.35,P= 0.08) and working in areas other than administration (ORP= 0.08). An age below 45 was associated with a higher degree of self-reported SHS exposure. The association between SHS and gender was different depending on occupational area with significantly more men exposed to SHS in administrative area and more women in health/social area (interaction between gender and occupational area,P= 0.02).

CONCLUSION

Importance of SHS exposure among prison employees and confirm the need for a comprehensive tobacco control policy including support to smoking cessation and better enforcement of the smoke-free regulation, especially where staff contributes to SHS. Particular attention has to be given to female employees.

Disease profiles of detainees in the Canton of Vaud in Switzerland: gender and age differences in substance abuse, mental health and chronic health conditions

BACKGROUND

Literature on the disease profile of prisoners that differentiates by age and gender remains sparse. This study aimed to describe the health of correctional inmates in terms of substance abuse problems and mental and somatic health conditions, and compare it by gender and age.

METHODS

This study examined cross-sectional data from the Canton of Vaud in Switzerland on the health conditions of detainees who were in prison on January 1, 2011 or entered prison in 2011. Health conditions validated by physician examination were reported using the International Classification of Diseases (ICD) version 10. The analyses were descriptive by groups of prisoners: the entire sample (All), Men, Older adults and Women.

RESULTS

A total of 1,664 individuals were included in the analysis. Men comprised 91.5 % of the sample and had a mean age of 33 years. The other 8.5 % were women and had an average age of 39. Older adults (i.e., age 50 and older) represented 7 % of the total sample. Overall, 80 % of inmates were non-Swiss citizens, but the proportion of Swiss prisoners was higher among the older adults (51 %) and women (29 %). Overall, 41 % of inmates self-reported substance abuse problems. Of those, 27 % were being treated by psychiatrists for behavioral disorders related to substance abuse. Chronic infectious diseases were found in 9 % of the prison population. In addition, 27 % of detainees suffered from serious mental health conditions. Gender and age had an influence on the disease profile of this sample: compared to the entire prison population, the older inmates were less likely to misuse illegal drugs and to suffer from communicable infections but exhibited more problems with alcohol and a higher burden of chronic health conditions. Female prisoners were more disposed to mental health problems (including drug abuse) and infectious diseases. In terms of chronic diseases, women suffered from the same conditions as men, but the diseases were more prevalent in women.

CONCLUSION

It is important to understand the different disease profiles of prisoners by gender and age, as it helps identify the needs of different groups and tailor age-and gender-specific interventions.

Improving public health by respecting autonomy: using social science research to enfranchise vulnerable prison populations

It is widely recognised that prisoners constitute a vulnerable population that is subject to numerous health inequalities and merits special protection. Improving prisoners' access to healthcare by ensuring adherence to the principle of equivalence has been the main focus of efforts to ensure that their health is not jeopardised. However, another means of respecting prisoners' autonomy and improving their health is to involve them (and prison staff) in social science research within prisons. Such research not only produces valuable data which can be used to assess whether the principle of equivalence is being respected; it also enfranchises prisoners by allowing them to air concerns about perceived ill-treatment and influence their environment. If prison authorities enable such research and adjust policy accordingly, both they and prisoners will benefit from the increased level of respect for prisoners' autonomy, and the improvements in individual and public health that flow from this. Conducting social science research in prisons enables the creation of a virtuous cycle of respect that makes prisons safer and healthier places.

An international smoking ban-how many lives will be saved?

Multicomponent tobacco control strategies are crucial to combat the ongoing global smoking challenge. In the twenty-first century, many countries have signed up to the World Health Organization Framework Convention on Tobacco Control, and in recent years a mounting number of countries and regions have implemented partial or complete smoking bans to protect the general public from passive smoke exposure. There is substantial evidence that workers, particularly in the hospitality sector, benefit from reduced exposure. More recently, several reports have appeared from different countries showing a temporal relationship between the introduction of a smoking ban and reduced hospital admissions for cardiovascular, respiratory and maternity outcomes. This will have a measurable benefit for public health, saving many lives. Multicomponent strategies could also reduce active smoking significantly if successfully implemented worldwide.

Attitudes of detainees and prison staff towards tobacco control policy in Switzerland: a qualitative interview study

PURPOSE

To explore detainees and staff's attitudes towards tobacco use, in order to assist prison administrators to develop an ethically acceptable tobacco control policy based on stakeholders' opinion.

DESIGN

Qualitative study based on in-depth semi-structured interviews with 31 prisoners and 27 staff prior (T1) and after the implementation (T2) of a new smoke-free regulation (2009) in a Swiss male post-trial prison consisting of 120 detainees and 120 employees.

RESULTS

At T1, smoking was allowed in common indoor rooms and most working places. Both groups of participants expressed the need for a more uniform and stricter regulation, with general opposition towards a total smoking ban. Expressed fears and difficulties regarding a stricter regulation were increased stress on detainees and strain on staff, violence, riots, loss of control on detainees, and changes in social life. At T2, participants expressed predominantly satisfaction. They reported reduction in their own tobacco use and a better protection against second-hand smoke. However, enforcement was incomplete. The debate was felt as being concentrated on regulation only, leaving aside the subject of tobacco reduction or cessation support.

CONCLUSION

Besides an appropriate smoke-free regulation, further developments are necessary in order to have a comprehensive tobacco control policy in prisons.

Second-hand tobacco smoke in prison: tackling a public health matter through research

OBJECTIVES

This action-research study conducted in a Swiss male post-trial detention centre (120 detainees and 120 staff) explored the attitudes of detainees and staff towards tobacco smoking. Tackling public health matters through research involving stakeholders in prisons implies benefits and risks that need exploration.

STUDY DESIGN

The observational study involved multiple strands (quantitative and qualitative components, and air quality measurements). This article presents qualitative data on participants' attitudes and expectations about research in a prison setting.

METHODS

Semi-structured interviews were used to explore the attitudes of detainees and staff towards smoking before and after a smoke-free regulation change in the prison in 2009. Specific coding and thematic content analysis for research were performed with the support of ATLAS.ti.

RESULTS

In total, 77 interviews were conducted (38 before the regulation change and 39 after the regulation change) with 31 detainees (mean age 35 years, range 22-60 years) and 27 prison staff (mean age 46 years, range 29-65 years). Both detainees and staff expressed satisfaction regarding their involvement in the study, and wished to be informed about the results. They expected concrete changes in smoke-free regulation, and that the research would help to find ways to motivate detainees to quit smoking.

CONCLUSION

Active involvement of stakeholders promotes public health. Interviewing detainees and prison staff as part of an action-research study aimed at tackling a public health matter is a way of raising awareness and facilitating change in prisons. Research needs to be conducted independently from the prison administrators in order to increase trust and to avoid misunderstandings.
