Could mainstream anti-smoking programs increase inequalities in tobacco use? New Zealand data from 1981-96

24-Year trends in educational inequalities in adult smoking prevalence in the context of a national tobacco control program: The case of Brazil

Brazil was a low and middle-income country (LMIC) in the late-1980s when it implemented a robust national tobacco-control program (NTCP) amidst rapid gains in national incomes and gender equality. We assessed changes in smoking prevalence between 1989 and 2013 by education level and related these changes to trends in educational inequalities in smoking. Data were from four nationally representative cross-sectional surveys (1989, n = 25,298; 2003 n = 3845; 2008 n = 28,938; 2013 n = 47,440, ages 25-69 years). We estimated absolute (slope index of inequality, SII) and relative (relative index of inequality, RII) educational inequalities in smoking prevalence, separately for males and females. Additional analyses stratified by birth-cohort to assess generational differences. Smoking declined significantly between 1989 and 2013 in all education groups but declines among females were steeper in higher-educated groups. Consequently, both absolute and relative educational inequalities in female smoking widened threefold between 1989 and 2013 (RII: 1.31 to 3.60, SII: 5.3 to 15.0), but absolute inequalities in female smoking widened mainly until 2003 (SII: 15.8). Conversely, among males, declines were steeper in higher-educated groups only in relative terms. Thus, relative educational inequalities in male smoking widened between 1989 and 2013 (RII: 1.58 to 3.19) but mainly until 2008 (3.22), whereas absolute equalities in male smoking were unchanged over the 24-year period (1989: 21.1 vs. 2013: 23.2). Younger-cohorts (born ≥1965) had wider relative inequalities in smoking vs. older-cohorts at comparable ages, particularly in the youngest female-cohorts (born 1979-1988). Our results suggest that younger lower-SES groups, especially females, may be particularly vulnerable to differentially higher smoking uptake in LMICs that implement population tobacco-control efforts amidst rapid societal gains.

Inequalities in smoking prevalence: a missed opportunity for tobacco control in Pakistan

Background

Pakistan is one of the highest tobacco consuming countries in South Asia and consumption is increasing. To implement equity orientated tobacco control policies, the most vulnerable groups must be identified. We aimed to identify these groups using the Pakistan Demographic and Health Survey (PDHS) 2012-13.

Methods

Descriptive statistics, univariate and multivariate analyses were used to explore household and participant characteristics associated with smoking inside the home or tobacco smoking, respectively. Survey weights were used to give nationally representative findings.

Results

Data for 12 931 households, 3132 men and 13 538 women were examined. About 58.3% of surveyed households were smoke-free, 39.1% were exposed to indoor tobacco smoke every day, 2.6% less frequently. Significantly more rural households were exposed to indoor tobacco smoke than urban households (45.2% versus 34.9%). Of men, 28.3% reported smoking compared with 1.3% of women. Smoking prevalence was higher in older age groups. Increasing wealth was associated with lower smoking prevalence and indoor smoking. For men, but not women, increasing education was associated with reduced smoking.

Conclusions

Inequalities in smoking behaviour impose harm to those who can least afford the financial and health costs. Future tobacco control policies in Pakistan must be sensitive to gender, geography and socio-economic status.

Proximate determinants of tuberculosis in Indigenous peoples worldwide: a systematic review

BACKGROUND

Indigenous peoples worldwide carry a disproportionate tuberculosis burden. There is an increasing awareness of the effect of social determinants and proximate determinants such as alcohol use, overcrowding, type 1 and type 2 diabetes, substance misuse, HIV, food insecurity and malnutrition, and smoking on the burden of tuberculosis. We aimed to understand the potential contribution of such determinants to tuberculosis in Indigenous peoples and to document steps taken to address them.

METHODS

We did a systematic review using seven databases (MEDLINE, Embase, CINAHL, Global Health, BIOSIS Previews, Web of Science, and the Cochrane Library). We identified English language articles published from Jan 1, 1980, to Dec 20, 2017, reporting the prevalence of proximate determinants of tuberculosis and preventive programmes targeting these determinants in Indigenous communities worldwide. We included any randomised controlled trials, controlled studies, cohort studies, cross-sectional studies, case reports, and qualitative research. Exclusion criteria were articles in languages other than English, full text not available, population was not Indigenous, focused exclusively on children or older people, and studies that focused on pharmacological interventions.

FINDINGS

Of 34 255 articles identified, 475 were eligible for inclusion. Most studies confirmed a higher prevalence of proximate determinants in Indigenous communities than in the general population. Diabetes was more frequent in Indigenous communities within high-income countries versus in low-income countries. The prevalence of alcohol use was generally similar to that among non-Indigenous groups, although patterns of drinking often differed. Smoking prevalence and smokeless tobacco consumption were commonly higher in Indigenous groups than in non-Indigenous groups. Food insecurity was highly prevalent in most Indigenous communities evaluated. Substance use was more frequent in Indigenous inhabitants of high-income countries than of low-income countries, with wide variation across Indigenous communities. The literature pertaining to HIV, crowding, and housing conditions among Indigenous peoples was too scant to draw firm conclusions. Preventive programmes that are culturally appropriate targeting these determinants appear feasible, although their effectiveness is largely unproven.

INTERPRETATION

Indigenous peoples were generally reported to have a higher prevalence of several proximate determinants of tuberculosis than non-Indigenous peoples, with wide variation across Indigenous communities. These findings emphasise the need for community-led, culturally appropriate strategies to address smoking, food insecurity, and diabetes in Indigenous populations as important public health goals in their own right, and also to reduce the burden of tuberculosis.

Socioeconomic differences in smoking in Jordan, Lebanon, Syria, and Palestine: A cross-sectional analysis of national surveys

Introduction

The association between education and wealth, as fundamental determinants of health, and smoking is well-established. Yet, social inequalities have received little attention in the expanding field of tobacco research in the Arab region. In this study, we examine inequalities in cigarette smoking by education and wealth in four Arab countries.

Methods

Utilizing the most recently available population-level data sets (Syria 2009 PAPFAM, Jordan 2012 DHS, Palestine 2010 Family Health Survey, and Lebanon 2004 PAPFAM), we tested the association between cigarette smoking and education and wealth–controlling for age, marital status, and region of residence–for each country, and among men and women depending on data availability.

Results

Cigarette smoking prevalence among Arab men is high– 51.3% in Syria, 39.7% in Palestine, and 42.1% in Lebanon; among women, prevalence is 8.4% in Syria, 10.9% in Jordan, and 24.3% Lebanon. Cigarette smoking shows the expected patterns inequalities by education among men in Syria, Palestine, and Lebanon, and among women in Jordan and Lebanon. On the other hand, wealth does not show a clear pattern in its association with cigarette smoking and, in some cases (men in Palestine and women in Syria) the behavioral risk is higher among the wealthiest.

Conclusions

Available data from 2004–2012 show that cigarette smoking among men and women in the four Arab countries is predominant among those with limited access to education as a fundamental cause. The weak or absent negative association between wealth and cigarette smoking suggests that access to material resources does not precipitate a reduction in the consumption of tobacco.

Changes to smoking habits and addiction following tobacco excise tax increases: a comparison of Māori, Pacific and New Zealand European smokers

OBJECTIVE

To compare changes in smoking habit and psychological addiction in Māori/Pacific and NZ European smokers in response to two annual excise tax increases from 2012 to 2014.

METHODS

Smokers from New Zealand cities completed questionnaires at three time points before and after two excise tax increases.

RESULTS

There were no significant differences in cigarettes per day or psychological addiction at baseline, but a linear decline in both measures was observed in Māori/Pacific and NZ European smokers. Cigarettes per day reduced at a greater rate for Māori/Pacific than NZ European smokers but dependence did not.

CONCLUSION

Results indicated that Māori/Pacific smokers' demand for cigarettes may be more price sensitive than NZ European smokers. Implications for Public Health: Tobacco excise tax may be particularly effective for Māori/Pacific smokers and may contribute to reductions in smoking-related health inequalities in NZ.

Critical Health Psychology

This commentary deals with two issues raised by Hepworth (this issue). Concerning definitions, it argues that critical health psychology needs to be more explicit in defining itself as politically left-wing, and that its central defining characteristic should be that it is research and practice which aims primarily to benefit the participants, regardless of any specific method or epistemology. Concerning the value of critical health psychology, it argues that work which has improved health on a global scale and which aims to reduce inequities is being done, but not by critical psychologists, and suggests a need for more action and less rhetoric.

Protecting children from taking up smoking: parents' views on what would help

ISSUE ADDRESSED

The present study investigated what factors the parents of children in low-income areas of Auckland, New Zealand, thought could help protect their children from smoking initiation.

METHODS

Participants in a large quasi-experimental trial that tested a community-, school- and family-based smoking-initiation intervention were asked in a questionnaire 'What could we do to help you protect your children from smoke and taking up smoking?' Free-text responses were divided into distinct meaning units and categorised independently by two of the researchers.

RESULTS

1806 participants (70% of parents who returned the questionnaire) completed the question. The majority of respondents (80%) were either Pacific Island or Māori mothers and 25% were current smokers. Five main categories of suggested strategies for preventing smoking initiation were identified: building children's knowledge of the ill-effects of smoking; denormalising smoking; reducing access to tobacco; building children's resilience; and health promotion activities. The most common suggestion was to educate children about smoking.

CONCLUSION

Building children's knowledge of smoking risks was the main strategy parents proposed. There was some support for banning smoking in most public areas and for tougher moves to stop tobacco sales to minors. Few parents suggested innovative or radical strategies, such as banning the sale of tobacco, fining children for smoking or use of competitions. So what? To ensure reductions in smoking initiation for lower socioeconomic and Māori and Pacific Island people, further research should engage Māori, Pacific Island and lower socioeconomic parents in a process that elicits innovative thinking about culturally acceptable strategies.

Evaluating return on investment in a school based health promotion and prevention program: the investment multiplier for the Stephanie Alexander Kitchen Garden National Program

Successful health promotion and disease prevention strategies in complex community settings such as primary schools rely on acceptance and ownership across community networks. Assessing multiplier impacts from investment on related community activity over time are suggested as key alongside evidence of program health effects on targeted groups of individuals in gauging community network engagement and ownership, dynamic impacts, and program long term success and return on investment. An Australian primary school based health promotion and prevention strategy, the Stephanie Alexander Kitchen Garden National Program (SAKGNP), which has been providing garden and kitchen classes for year 3-6 students since 2008, was evaluated between 2011 and 2012. Returns on Australian Federal Government investment for school infrastructure grants up to $60,000 are assessed up to and beyond a two year mutual obligation period with: (i) Impacts on student lifestyle behaviours, food choices and eating habits surveyed across students (n = 491 versus 260) and parents (n = 300 versus 234) in 28 SAKGNP and 14 matched schools, controlling for school and parent level confounders and triangulated with SAKGNP pre-post analysis; (ii) Multiplier impacts of investment on related school and wider community activity up to two years; and (iii) Evidence of continuation and program evolution in schools observed beyond two years. SAKGNP schools showed improved student food choices (p = 0.024) and kitchen lifestyle behaviour (p = 0.019) domains compared to controls and in pre-post analysis where 20.0% (58/290) reported eating fruit and vegetables more often and 18.6% (54/290) preparing food at home more often. No significant differences were found in case control analysis for eating habits or garden lifestyle behaviour domains, although 32.3% of children helped more in the garden (91/278) and 15.6% (45/289) ate meals together more often in pre-post analysis. The multiplier impact on total community activity up to two years was 5.07 ($226,737/$44,758); 1.60 attributable to school, and 2.47 to wider community, activity. All 8 schools observed beyond two years continued garden and kitchen classes, with an average 17% scaling up and one school fully integrating staff into the curriculum. In conclusion evidence supports the SAKGNP to be a successful health promotion program with high community network impacts and return on investment in practice.

Trends in smoking in Canada from 1950 to 2011: progression of the tobacco epidemic according to socioeconomic status and geography

PURPOSE

Smoking has declined in Canada in recent years. However, it is not clear whether differences in current smoking by socioeconomic status have increased, decreased, or remained unchanged in Canada.

METHODS

We examined rates of current smoking by sex, education, and province from 1950 to 2011. Differences in current smoking, initiation, and cessation were summarized using relative and absolute measures.

RESULTS

Between 1950 and 2011, the prevalence of current smoking (including daily and non-daily) among adults aged 20 years and older decreased steadily in men from 68.9 % (95 % CI 63.9-73.3) to 18.6 % (14.9-22.1) but in women increased slightly from 38.2 % (32.3-42.2) in 1950 to 39.1 % (36.4-41.2) in 1959 before declining to 15.4 % (11.9-18.9) in 2011. Among men, there was an inverse association between educational attainment and smoking which was consistent from 1950 to 2011. A similar gradient emerged in the mid-1960s in women. Absolute differences in rates of smoking across levels of education increased despite overall declines in smoking across all levels of education. Rates of smoking in women and men were higher in the Atlantic Provinces and Quebec, although in men these differences have declined since the 1990s. In a subset of data from 1999 to 2011, those with lower levels of education had higher levels of smoking initiation and lower levels of cessation.

CONCLUSIONS

Smoking rates have fallen over time but socioeconomic differences have increased. Smoking prevalence peaked later in lower socioeconomic status (SES) groups, and rates of decline in lower SES groups and certain provinces have been less steep. This suggests that SES gradients emerge rapidly in later stages of the tobacco epidemic and may have increased through greater efficacy of tobacco control policies in reducing smoking among those of higher SES compared to those of lower SES. Tailored approaches may be required to reduce smoking rates in those of lower SES and narrow SES differences.

An innovative team-based stop smoking competition among Māori and Pacific Island smokers: rationale and method for the study and its evaluation

BACKGROUND

Māori and Pacific Island people have significantly higher smoking rates compared to the rest of the New Zealand population. The main aim of this paper is to describe how knowledge of Indigenous people's practices and principles can be combined with proven effective smoking cessation support into a cessation intervention appropriate for Indigenous people.

METHODS/DESIGN

A literature review was conducted to identify what cultural principles and practices could be used to increase salience, and what competition elements could have an impact on efficacy of smoking cessation. The identified elements were incorporated into the design of a cessation intervention.

DISCUSSION

Cultural practices incorporated into the intervention include having a holistic family or group-centred focus, inter-group competitiveness, fundraising and ritual pledging. Competition elements included are social support, pharmacotherapy use, cash prize incentives and the use of a dedicated website and iPad application. A pre-test post-test will be combined with process evaluation to evaluate if the competition results in triggering mass-quitting, utilisation of pharmacotherapy and in increasing sustained smoking cessation and to get a comprehensive understanding of the way in which they contribute to the effect. The present study is the first to describe how knowledge about cultural practices and principles can be combined with proven cessation support into a smoking cessation contest. The findings from this study are promising and further more rigorous testing is warranted.

Predictors of cigarette use amongst Pacific youth in New Zealand

Background

Despite progressive population health policies to reduce tobacco harm, smoking prevalence continues to be inequitable amongst key ethnic groups in New Zealand. The purpose of this study is to describe the predictors of cigarette use amongst Pacific youth in New Zealand.

Methods

Data were collected as part of Youth’07, a nationally representative survey of the health and well-being of New Zealand adolescents. The study sample comprised 5471 students and this includes 1,178 were Pacific youth.

Results

The smoking prevalence rate for Pacific youth was twice that of New Zealand European youth. Pacific girls and older age groups, ages 16–17, smoked more than Pacific boys and younger adolescents. Pacific youth from higher and mid-deprivation neighbourhoods smoked at twice the rate of youth from low deprivation areas. Local neighbourhood stores (dairies) were the most used location for purchasing cigarettes, and only 12.7% of under-aged adolescents were asked “most of the time” for age identification. Pacific adolescent smoking was associated with parental smoking, peer-group smoking and binge drinking. Parents not knowing the whereabouts of adolescents during after-school hours and night-times were also associated with adolescent smoking. A majority of Pacific adolescent smokers (70.2%) had tried to quit smoking.

Conclusion

The strategies for addressing ethically the issue of equal health for all is to allocate increased public health investments towards targeted quit-smoking treatment programmes for Pacific youth in New Zealand. Further qualitative studies with Pacific youth to inform the development of culturally-appropriate youth-focused quit-substance interventions is recommended.

Socioeconomic and geographic patterning of smoking behaviour in Canada: a cross-sectional multilevel analysis

OBJECTIVE

To describe the socioeconomic and geographic distribution of smoking behaviour in Canada among 19,383 individuals (51% women) aged 15-85 years.

METHODS

Current smoking and quitting were modeled using standard and multilevel logistic regression. Markers of socioeconomic status (SES) were education and occupation. Geography was defined by Canadian Provinces.

RESULTS

The adjusted prevalence of current smoking was 20.2% (95% confidence interval [CI]: 18.8-21.7) and 63.7% (95% CI: 61.1-66.3) of ever smokers had quit. Current smoking decreased and quitting increased with increasing SES. The adjusted prevalence of current smoking was 32.8% (95% CI: 28.4-37.5) among the least educated compared to 11.0% (95% CI: 8.9-13.4) for the highest educated. Among the least educated, 53.0% (95% CI: 46.8-59.2) had quit, rising to 68.7% (95% CI: 62.7-74.1) for the most educated. There was substantial variation in current smoking and quitting at the provincial level; current smoking varied from 17.9% in British Columbia to 26.1% in Nova Scotia, and quitting varied from 57.4% in Nova Scotia to 67.8% in Prince Edward Island. Nationally, increasing education and occupation level were inversely associated with current smoking (odds ratio [OR] 0.64, 95% CI: 0.60-0.68 for education; OR 0.82, 95% CI: 0.77-0.87 for occupation) and positively associated with quitting (OR 1.27, 95% CI: 1.16-1.40 for education; OR 1.20, 95% CI: 1.12-1.27 for occupation). These associations were consistent in direction across provinces although with some variability in magnitude.

CONCLUSION

Our findings indicate that socioeconomic inequalities in smoking have persisted in Canada; current smoking was less likely and quitting was more likely among the better off groups and in certain provinces. Current prevention and cessation policies have not been successful in improving the situation for all areas and groups. Future efforts to reduce smoking uptake and increase cessation in Canada will need consideration of socioeconomic and geographic factors to be successful.

Pregnant Māori Smokers’ Perception of Cessation Support and How It Can Be More Helpful

This study aimed to investigate the perception of smoking cessation services and products by pregnant Māori (New Zealand's Indigenous people) smokers and identify how these can be improved. Semi-structured face-to-face interviews were conducted with 60 pregnant Māori smokers. Most of the women (82%) had been advised to stop smoking, but few (21%) felt influenced by the advice. In addition, the women in this study felt that health provider support needed to be more encouraging, understanding and more readily available. Many (78%) had come across smokefree pamphlets, but few had read them. Only four women had been given a booklet specifically aimed at pregnant Māori women. Several women thought that the promotion of smokefree pregnancies needed to be aimed at the whole whānau (extended family). The main conclusions were that motivation to quit could be enhanced by delivery of a clear, consistent and repeated message from multiple sources, backed up with effective, supportive and encouraging services and education resources about risks and smoking cessation options. Primary health care interventions delivering a range of services need to be flexible – for example, by visiting pregnant women in their home – and need to target the whole expectant whānau, instead of focusing on pregnant women in isolation.

Impact of the 2005 smoke-free policy in Italy on prevalence, cessation and intensity of smoking in the overall population and by educational group

AIMS

To estimate the immediate as well as the longer-term impact of the 2005 smoke-free law on smoking prevalence, cessation and intensity both in the overall population and separately by educational level.

DESIGN

Interrupted time-series analyses of 11 cross-sectional nationally representative surveys.

SETTING

Italy, 1999-2010.

PARTICIPANTS

Adults aged 20-64 years.

MEASUREMENTS

For each year we computed the prevalence of current smoking, the quit ratio and the mean number of cigarettes smoked per day. All measures were standardized by age. Segmented linear regression analyses were performed for each smoking variable separately by sex.

FINDINGS

Among males, smoking prevalence decreased by 2.6% (P = 0.002) and smoking cessation increased by 3.3% (P = 0.006) shortly after the ban, but both measures tended to return to pre-ban values in the following years. This occurred among both highly and low-educated males. Among low-educated females, the ban was followed by a 1.6% decrease (P = 0.120) in smoking prevalence and a 4.5% increase in quit ratios (P < 0.001). However, these favourable trends reversed over the following years. Among highly educated females, trends in smoking prevalence and cessation were not altered by the ban. Among both males and females, long-term trends in the daily number of cigarettes, which were already declining well before the implementation of the policy, changed to a minor extent.

CONCLUSION

The impact of the Italian smoke-free policy on smoking and inequalities in smoking was short-term. Smoke-free policies may not achieve the secondary effect of reducing smoking prevalence in the long term, and they may have limited effects on inequalities in smoking.

Interventions for tobacco use prevention in Indigenous youth

BACKGROUND

Tobacco use in Indigenous populations (people who have inhabited a country for thousands of years) is often double that in the non-Indigenous population. Addiction to nicotine usually begins during early adolescence and young people who reach the age of 18 as non-smokers are unlikely to become smokers thereafter. Indigenous youth in particular commence smoking at an early age, and a disproportionate burden of substance-related morbidity and mortality exists as a result.

OBJECTIVES

To evaluate the effectiveness of intervention programmes to prevent tobacco use initiation or progression to regular smoking amongst young Indigenous populations and to summarise these approaches for future prevention programmes and research.

SEARCH METHODS

The Cochrane Tobacco Addiction Group Specialised Register was searched in November 2011, with additional searches run in MEDLINE. Online clinical trial databases and publication references were also searched for potential studies.

SELECTION CRITERIA

We included randomized and non-randomized controlled trials aiming to prevent tobacco use initiation or progression from experimentation to regular tobacco use in Indigenous youth. Interventions could include school-based initiatives, mass media, multi-component community level interventions, family-based programmes or public policy.

DATA COLLECTION AND ANALYSIS

Data pertaining to methodology, participants, interventions and outcomes were extracted by one reviewer and checked by a second, whilst information on risk of bias was extracted independently by a combination of two reviewers. Studies were assessed by qualitative narrative synthesis, as insufficient data were available to conduct a meta-analysis. The review process was examined by an Indigenous (Aboriginal) Australian for applicability, acceptability and content.

MAIN RESULTS

Two studies met all of the eligibility criteria for inclusion within the review and a third was identified as ongoing. The two included studies employed multi-component community-based interventions tailored to the specific cultural aspects of the population and were based in Native American populations (1505 subjects in total). No difference was observed in weekly smoking at 42 months follow-up in the one study assessing this outcome (skills-community group versus control: risk ratio [RR] 0.95, 95% CI 0.78 to 1.14; skills-only group versus control: RR 0.86, 95% CI 0.71 to 1.05). For smokeless tobacco use, no difference was found between the skills-community arm and the control group at 42 weeks (RR 0.93, 95% CI 0.67 to 1.30), though a significant difference was observed between the skills-only arm and the control group (RR 0.57, 95% CI 0.39 to 0.85). Whilst the second study found positive changes for tobacco use in the intervention arm at post test (p < 0.05), this was not maintained at six month follow-up (change score -0.11 for intervention and 0.07 for control). Both studies were rated as high or unclear risk of bias in seven or more domains (out of a total of 10).

AUTHORS' CONCLUSIONS

Based on the available evidence, a conclusion cannot be drawn as to the efficacy of tobacco prevention initiatives tailored for Indigenous youth. This review highlights the paucity of data and the need for more research in this area. Smoking prevalence in Indigenous youth is twice that of the non-Indigenous population, with tobacco experimentation commencing at an early age. As such, a significant health disparity exists where Indigenous populations, a minority, are over-represented in the burden of smoking-related morbidity and mortality. Methodologically rigorous trials are needed to investigate interventions aimed at preventing the uptake of tobacco use amongst Indigenous youth and to assist in bridging the gap between tobacco-related health disparities in Indigenous and non-Indigenous populations.

Trends in socioeconomic inequalities in smoking prevalence, consumption, initiation, and cessation between 2001 and 2008 in the Netherlands. Findings from a national population survey

Background

Widening of socioeconomic status (SES) inequalities in smoking prevalence has occurred in several Western countries from the mid 1970’s onwards. However, little is known about a widening of SES inequalities in smoking consumption, initiation and cessation.

Methods

Repeated cross-sectional population surveys from 2001 to 2008 (n ≈ 18,000 per year) were used to examine changes in smoking prevalence, smoking consumption (number of cigarettes per day), initiation ratios (ratio of ever smokers to all respondents), and quit ratios (ratio of former smokers to ever smokers) in the Netherlands. Education level and income level were used as indicators of SES and results were reported separately for men and women.

Results

Lower educated respondents were significantly more likely to be smokers, smoked more cigarettes per day, had higher initiation ratios, and had lower quit ratios than higher educated respondents. Income inequalities were smaller than educational inequalities and were not all significant, but were in the same direction as educational inequalities. Among women, educational inequalities widened significantly between 2001 and 2008 for smoking prevalence, smoking initiation, and smoking cessation. Among low educated women, smoking prevalence remained stable between 2001 and 2008 because both the initiation and quit ratio increased significantly. Among moderate and high educated women, smoking prevalence decreased significantly because initiation ratios remained constant, while quit ratios increased significantly. Among men, educational inequalities widened significantly between 2001 and 2008 for smoking consumption only.

Conclusions

While inequalities in smoking prevalence were stable among Dutch men, they increased among women, due to widening inequalities in both smoking cessation and initiation. Both components should be addressed in equity-oriented tobacco control policies.

Socio-economic disadvantage at the area level poses few direct barriers to smoking cessation for Australian smokers: findings from the International Tobacco Control Australian cohort survey

INTRODUCTION

Area-level indicators of socio-economic variation are frequently included in models of individual health outcomes. Area disadvantage is linearly related to smoking prevalence, but its relation to cessation outcomes is less well understood.

AIMS

To explore the relationship between area-level disadvantage and prospective data on smoking cessation.

DESIGN AND METHODS

The Australian cohort of the International Tobacco Control Four-Country Survey (N = 3503) was used to prospectively examine the contribution of area-level socio-economic disadvantage to predicting three important smoking-cessation outcomes: making a quit attempt, achieving 1 month abstinence and achieving 6 month abstinence from smoking, while controlling for individual-level socio-economic indicators and other individual-level covariates related to smoking cessation.

RESULTS

Only two independent associations were observed between socio-economic disadvantage and cessation outcomes. Area-level disadvantage was related to 1 month abstinence in a non-linear fashion, and the individual experience of smoking-induced deprivation was associated with a lower likelihood of making quit attempts.

DISCUSSION

Despite the documented higher prevalence of smoking among the more disadvantaged and in more disadvantaged areas, socio-economic disadvantage was not consistently related to making quit attempts, nor to medium-term success. Nevertheless, indirect effects of disadvantage, like its impact on psychological distress, cannot be ruled out, and considering smokers' individual psychosocial circumstances is likely to aid cessation efforts.

CONCLUSION

Socio-economic disadvantage, particularly at the area level, poses few direct barriers to smoking cessation.

Access to general practitioner services amongst underserved Australians: a microsimulation study

BACKGROUND

One group often identified as having low socioeconomic status, those living in remote or rural areas, are often recognised as bearing an unequal burden of illness in society. This paper aims to examine equity of utilisation of general practitioner services in Australia.

METHODS

Using the 2005 National Health Survey undertaken by the Australian Bureau of Statistics, a microsimulation model was developed to determine the distribution of GP services that would occur if all Australians had equal utilisation of health services relative to need.

RESULTS

It was estimated that those who are unemployed would experience a 19% increase in GP services. Persons residing in regional areas would receive about 5.7 million additional GP visits per year if they had the same access to care as Australians residing in major cities. This would be a 18% increase. There would be a 20% increase for inner regional residents and a 14% increase for residents of more remote regional areas. Overall there would be a 5% increase in GP visits nationally if those in regional areas had the same access to care as those in major cities.

CONCLUSION

Parity is an insufficient goal and disadvantaged persons and underserved areas require greater access to health services than the well served metropolitan areas due to their greater poverty and poorer health status. Currently underserved Australians suffer a double disadvantage: poorer health and poorer access to health services.

Acculturation status has a modest effect on smoking prevalence among a cohort of Pacific fathers in New Zealand

OBJECTIVE

This article explores the relationship between smoking prevalence and acculturation among a cohort of Pacific Island fathers resident in New Zealand.

METHODS

Overall, 766 Pacific fathers were included in the analysis. Self-reported smoking status was assessed and compared with data from a robust epidemiological measure of acculturation status specifically designed for use amongst the Pacific population. Additional variables describing socio-demographic and other circumstances of the participating fathers were also incorporated in the analysis because of their known association with smoking behaviour.

RESULTS

Overall, 40.3% of Pacific fathers were current smokers. Multivariable logistic regression showed that acculturation status was associated with smoking crude (p<0.001) and multivariable logistic regression models, when adjusting to socio-demographic variables (p=0.008).

CONCLUSION

Smoking rates for Pacific fathers in New Zealand are high. There appears to be a modest effect of acculturation on smoking prevalence, where those fathers with higher Pacific cultural identity have the lowest smoking rates. It is opined that the strength of identification and a holistic view of health enhances the motivations of Pacific fathers to be smoke-free in New Zealand.

IMPLICATIONS

Strategies which maintain, enhance, and incorporate fathers' Pacific cultural identity may be a useful addition to comprehensive tobacco control strategies to reduce the prevalence of smoking in Pacific people living in New Zealand.

Best practice for prevention and treatment of cardiovascular disease through an equity lens: a review

BACKGROUND

Despite declining rates of cardiovascular disease (CVD) mortality in developed countries, lower socioeconomic groups continue to experience a greater burden of the disease. There are now many evidence-based treatments and prevention strategies for the management of CVD and it is essential that their impact on the more disadvantaged group is understood if socioeconomic inequalities in CVD are to be reduced.

AIMS

To determine whether key interventions for CVD prevention and treatment are effective among lower socioeconomic groups, to describe barriers to their effectiveness and the potential or actual impact of these interventions on the socioeconomic gradient in CVD.

METHODS

Interventions were selected from four stages of the CVD continuum. These included smoking reduction strategies, absolute risk assessment, cardiac rehabilitation, secondary prevention medications, and heart failure self-management programmes. Electronic searches were conducted using terms for each intervention combined with terms for socioeconomic status (SES).

RESULTS

Only limited evidence was found for the effectiveness of the selected interventions among lower SES groups and there was little exploration of socioeconomic-related barriers to their uptake. Some broad themes and key messages were identified. In the majority of findings examined, it was clear that the underlying material, social and environmental factors associated with disadvantage are a significant barrier to the effectiveness of interventions.

CONCLUSION

Opportunities to reduce socioeconomic inequalities occur at all stages of the CVD continuum. Despite this, current treatment and prevention strategies may be contributing to the widening socioeconomic-CVD gradient. Further research into the impact of best-practice interventions for CVD upon lower SES groups is required.

Socio-economic status and smoking in Canada, 1999-2006: has there been any progress on disparities in tobacco use?

OBJECTIVES

Comprehensive tobacco control policies implemented in Canada have succeeded in lowering overall smoking prevalence; however, the extent to which they have impacted socio-economic disparities in tobacco use is not known. This study examined smoking rates and related measures across socio-economic groups over a 7-year period in Canada.

METHODS

Regression analyses tested associations between smoking-related outcomes (prevalence, frequency, consumption, quit intentions and attempts, quit ratios), education level and time, using data from adults 25 years and older who completed the 1999 to 2006 waves of the Canadian Tobacco Use Monitoring Survey (CTUMS), a repeated cross-sectional survey with nationally representative samples (n = 86,971).

RESULTS

Between 1999 and 2006, smoking prevalence, daily smoking, and cigarette consumption decreased, while the proportion of smokers who planned to quit increased, as did the proportion of ever-smokers who had quit. However, significant educational differences were observed: Canadians with less education had greater odds of current smoking (prevalence approximately doubled between the most and least educated groups) and daily smoking, and consumed more cigarettes, compared to university graduates. Highly-educated ever-smokers were also more likely to have quit smoking. These disparities remained stable over the time period studied. Intentions and attempts to quit were not consistently associated with education.

CONCLUSIONS

The decline in smoking among Canadians between 1999 and 2006 represents a major public health achievement. However, considerable smoking-related disparities exist between socio-economic groups, and have changed very little. Therefore, while recent programs and policies have succeeded in reducing overall tobacco use, they have not addressed socio-economic disparities.

Keeping Kids Smokefree: rationale, design, and implementation of a community, school, and family-based intervention to modify behaviors related to smoking among Māori and Pacific Island children in New Zealand

Despite a concerted, sustained and comprehensive tobacco control effort, smoking is prevalent among young people in New Zealand, particularly for Māori and Pacific Island teenagers. Many took up smoking in their pre-teen years. New Zealand research has shown that daily smoking by children aged 14-15 years is strongly influenced by parental smoking. The Keeping Kids Smokefree study is investigating whether changing parental smoking behavior and attitudes via a community-partnership approach with parents, schools, and local health providers can reduce smoking initiation by 11-12 year olds. It is a quasi-experimental trial involving four schools in an urban area of high social deprivation with large numbers of Māori and Pacific Islands families. Schools were allocated to intervention or control and the intervention was developed through a process of engagement with the schools, parents of children and local healthcare organizations. This article describes the rationale, context, methodology and methods involved in establishing the study. Building Māori and Pacific Islander research capacity was a secondary objective of the study.

The Framework Convention on Tobacco Control and health promotion: strengthening the ties

Successful tobacco control efforts in developed countries have provided an illustration of the application of health promotion principles, most notably the critical value of social mobilization for change and use of comprehensive health promotion strategies. Tobacco control efforts in developed countries are now starting to grapple with the challenge of closing the health equity gap. In developed countries, the Framework Convention on Tobacco Control (FCTC), though derived from a global social movement, is facing challenges in implementation because of relatively little support from the population as a whole, along with weak government infrastructure. Furthermore, developing countries are often more concerned about the Millennium Development Goals (MDGs) and access to primary health care, not to mention poverty alleviation in general, than tobacco use and non-communicable diseases. Health promotion and the FCTC have shared interests in relation to both health equity and capacity building. Therefore, a civil society coalition built around these common interests--and broader issues--may provide a stronger support for FCTC implementation. Strengthening the ties between health promotion and the FCTC could lead to stronger advocacy, better knowledge management systems, more integrated community-based programs, and stronger workforce capacity. These, in turn, could reduce tobacco smoking and other risks to health, as well as help close the health equity gap in developed and developing countries.

Does socioeconomic inequality explain ethnic differences in nicotine dependence? Evidence from a New Zealand birth cohort

OBJECTIVE

The present study examined the role of socioeconomic status and cultural identity in the association between ethnicity and nicotine dependence, in a birth cohort of >1000 methods young people studied to age 30.

METHODS

Data were gathered on ethnicity, cultural identification, nicotine dependence, and socioeconomic factors, as part of a longitudinal study of a New Zealand birth cohort (the Christchurch Health and Development Study).

RESULTS

Those reporting Māori identity had rates of nicotine dependence that were significantly higher (p < 0.05) than rates for non-Māori. Control for socioeconomic factors reduced the associations between ethnic identity and nicotine dependence to statistical non-significance. In addition, there was no evidence of a statistically significant association between Māori cultural identity and nicotine dependence, nor was there evidence of gender differences in the association between ethnic identity and nicotine dependence, after controlling for socioeconomic factors.

CONCLUSIONS

The higher rates of nicotine dependence observed among Māori appear to be attributable to differences in socioeconomic status. Efforts to improve the socioeconomic standing of Māori should therefore help to reduce rates of nicotine dependence in this population.

Theorising interventions as events in systems

Conventional thinking about preventive interventions focuses over simplistically on the "package" of activities and/or their educational messages. An alternative is to focus on the dynamic properties of the context into which the intervention is introduced. Schools, communities and worksites can be thought of as complex ecological systems. They can be theorised on three dimensions: (1) their constituent activity settings (e.g., clubs, festivals, assemblies, classrooms); (2) the social networks that connect the people and the settings; and (3) time. An intervention may then be seen as a critical event in the history of a system, leading to the evolution of new structures of interaction and new shared meanings. Interventions impact on evolving networks of person-time-place interaction, changing relationships, displacing existing activities and redistributing and transforming resources. This alternative view has significant implications for how interventions should be evaluated and how they could be made more effective. We explore this idea, drawing on social network analysis and complex systems theory.

Pathways of disadvantage and smoking careers: evidence and policy implications

OBJECTIVES

To investigate in older industrialised societies (a) how social disadvantage contributes to smoking risk among women (b) the role of social and economic policies in reducing disadvantage and moderating wider inequalities in life chances and living standards.

METHODS

Review and analysis of (a) the effects of disadvantage in childhood and into adulthood on women's smoking status in early adulthood (b) policy impacts on the social exposures associated with high smoking risk.

MAIN RESULTS

(a) Smoking status--ever smoking, current smoking, heavy smoking, and cessation--is influenced not only by current circumstances but by longer term biographies of disadvantage (b) social and economic policies shape key social predictors of women's smoking status, including childhood circumstances, educational levels and adult circumstances, and moderate inequalities in the distribution of these dimensions of life chances and living standards. Together, the two sets of findings argue for a policy toolkit that acts on the distal determinants of smoking, with interventions targeting the conditions in which future and current smokers live.

CONCLUSIONS

An approach to tobacco control is advocated that combines changing smoking habits with reducing inequalities in the social trajectories in which they are embedded. Policies to level up opportunities and living standards across the lifecourse should be championed as part of an equity oriented approach to reducing the disease burden of cigarette smoking.

What potential has tobacco control for reducing health inequalities? The New Zealand situation

In this Commentary, we aim to synthesize recent epidemiological data on tobacco and health inequalities for New Zealand and present it in new ways. We also aim to describe both existing and potential tobacco control responses for addressing these inequalities.

In New Zealand smoking prevalence is higher amongst Māori and Pacific peoples (compared to those of "New Zealand European" ethnicity) and amongst those with low socioeconomic position (SEP). Consequently the smoking-related mortality burden is higher among these populations. Regarding the gap in mortality between low and high socioeconomic groups, 21% and 11% of this gap for men and women was estimated to be due to smoking in 1996–99. Regarding the gap in mortality between Māori and non-Māori/non-Pacific, 5% and 8% of this gap for men and women was estimated to be due to smoking. The estimates from both these studies are probably moderate underestimates due to misclassification bias of smoking status. Despite the modest relative contribution of smoking to these gaps, the absolute number of smoking-attributable deaths is sizable and amenable to policy and health sector responses.

There is some evidence, from New Zealand and elsewhere, for interventions that reduce smoking by low-income populations and indigenous peoples. These include tobacco taxation, thematically appropriate mass media campaigns, and appropriate smoking cessation support services. But there are as yet untried interventions with major potential. A key one is for a tighter regulatory framework that could rapidly shift the nicotine market towards pharmaceutical-grade nicotine (or smokeless tobacco products) and away from smoked tobacco.

Observed smoking in cars: a method and differences by socioeconomic area

OBJECTIVES

To establish a reproducible method to estimate he point prevalence of smoking and second-hand smoke (SHS) exposure in cars, and to compare this prevalence between two areas of contrasting socioeconomic status.

METHOD

A method involving two teams of observers was developed and evaluated. It involved observing 16,055 cars in Wellington, New Zealand. Two of the observation sites represented a high and a low area of deprivation (based on a neighbourhood deprivation index) and three were in the central city.

RESULTS

A 4.1% point prevalence of smoking in cars was observed (95% confidence interval (CI) 3.8% to 4.4%). There was a higher prevalence of smoking in cars in the high deprivation area relative to the other sites, and particularly compared to the low deprivation area (rate ratio relative to the latter 3.2, 95% CI 2.6 to 4.0). Of cars with smoking, 23.7% had other occupants being exposed to SHS. Cars with smoking and other occupants were significantly more likely to have a window open (especially if the smoker was not the driver). The observation method developed was practical, and inter-observer agreement was high (kappa value for the "smoking seen in car" category 0.95).

CONCLUSIONS

Observational studies can be an effective way of investigating smoking in cars. The data from this survey suggest that smoking in cars occurs at a higher rate in relatively deprived populations and hence may contribute to health inequalities. Fortunately, there are a number of policy options for reducing SHS exposure in cars including mass media campaigns and laws for smoke-free cars.

What is the contribution of smoking and socioeconomic position to ethnic inequalities in mortality in New Zealand?

BACKGROUND

Mortality rates for Māori are twice those for non-Māori in New Zealand. We have assessed the contribution of tobacco smoking and socioeconomic position to these inequalities in 45-74-year-old census respondents during 1981-84 and 1996-99 (2.3 and 2.7 million person-years, respectively).

METHODS

We used linked census and mortality cohort datasets with measures of socioeconomic position (household income, highest educational qualification, car access, labour-force status, and neighbourhood deprivation) and smoking (never, ex, current). We used direct standardisation to adjust for smoking and Poisson regression to adjust for socioeconomic position.

FINDINGS

The apparent contribution of smoking to mortality differences between Māori and non-Māori non-Pacific people was greatest for women in 1996-99 (8% reduction in standardised rate difference); it had increased from 3% in 1981-84. The corresponding reductions in men were 5% in 1996-99 and -1% in 1981-84. The apparent contribution of socioeconomic factors to mortality differences between Māori and non-Māori non-Pacific was greatest for men (39% in 1981-84 and 37% in 1996-99) and increased over time for women (from 23% in 1981-84 to 32% in 1996-99).

INTERPRETATION

Although small, the contribution of smoking to ethnic inequalities in mortality increased over time and might grow more during the next two decades if differences in smoking between ethnic groups continue to increase. Better measurement of socioeconomic position (eg, lifecourse measures, asset wealth) might increase the proportion of ethnic inequalities attributable to socioeconomic position, perhaps to about half. Action to redress socioeconomic gaps and control of tobacco use will both be important in reducing ethnic inequalities in health.

Evidence into policy and practice? Measuring the progress of U.S. and U.K. policies to tackle disparities and inequalities in U.S. and U.K. health and health care

Health policy in both the United States and the United Kingdom has recently shifted toward a much greater concern with disparities and inequalities in health and health care. As evidence for these disparities and inequalities mounts, the different approaches in each country present specific challenges for policy and practice. These differences are most apparent in the mechanisms by which the progress of such policies is measured. This article compares the United States' and United Kingdom's strategies to gauge the challenges for policymakers in order to inform policy and practice. A cross-national comparison of selected measurement mechanisms identifies lessons for policy and practice in both countries.
