Outcomes of a culturally informed weight-loss competition for New Zealand Indigenous and Pacific peoples: a quasi-experimental trial.

BACKGROUND: Reducing obesity prevalence among marginalised subgroups with disproportionately high obesity rates is challenging. Given the promise of incentives and group-based programmes we trialled a culturally tailored, team-based weight-loss competition with New Zealand Maori (Indigenous) and Pacific Island people. METHODS: A quasi-experimental 12-months trial was designed. The intervention consisted of three six-months competitions, each with seven teams of seven members. Eligible participants were aged 16 years and older, with a BMI ≥30 kg/m2 and being at risk of or already diagnosed with type-2 diabetes or cardiovascular disease. Height, weight and waist circumference were measured at baseline, 6 and 12 months. RESULTS: Recruitment of a control group (n = 29) versus the intervention (n = 132) was poor and retention rates were low (52 and 27% of intervention participants were followed-up at six and 12 months, respectively). Thus, analysis of the primary outcome of individual percentage weight loss was restricted to the 6-months follow-up data. Although not significant, the intervention group appeared to lose more weight than the control group, in both the intention to treat and complete-case analyses. CONCLUSIONS: The intervention promoted some behaviour change in eating behaviours, and a resulting trend toward a reduction in waist circumference.

Perspectives of key stakeholders and smokers on a very low nicotine content cigarette-only policy: qualitative study.

AIMS: To investigate views of New Zealand key stakeholders (stakeholders) and smokers on very low nicotine content (VLNC) cigarettes, and a policy mandating that only VLNC cigarettes are available for sale. METHODS: Using a semi-structured interview schedule, we interviewed 17 stakeholders and held focus groups with 21 smokers. Questions were asked about VLNC cigarettes and a VLNC cigarette-only policy. Smokers were given approximately 15 VLNC cigarettes to take home and smoke. One week after the focus groups, 17 smokers were interviewed. Data were analysed using a general inductive approach. RESULTS: Stakeholders and smokers were largely unconvinced of the value of a mandated reduction in nicotine in cigarettes. After smoking VLNC cigarettes, smokers had less interest in them but would support them being sold alongside high nicotine content (HNC) cigarettes at a much cheaper price. CONCLUSION: The government is not likely to mandate nicotine reduction in cigarettes if there is a perceived lack of support from stakeholders or smokers. However, they could make VLNC cigarettes available as an option for smokers utilising a differential tax favouring VLNC cigarettes. If this were combined with better access to nicotine containing e-cigarettes, smokers may shift away from HNC cigarettes.

Smoking in Pregnancy Among Indigenous Women in High-Income Countries: A Narrative Review.

INTRODUCTION: Pregnant women in socioeconomically disadvantaged circumstances, such as Indigenous women, have a high prevalence of smoking. Tobacco smoking is the most significant reversible risk factor for the health of Indigenous pregnant women and their babies. METHODS: As researchers working in this specialized area, we conducted a narrative review of the literature on smoking among Indigenous pregnant women in the United States, Canada, New Zealand, and Australia. We summarize prevalence and factors influencing tobacco use, interventions, and evidence gaps for tobacco control and smoking cessation. Recommendations are made for future interventions, policy changes, and much-needed research. RESULTS: Common themes emerging across the four countries reveal opportunities for cross-cultural collaborative studies and trials. These include the social-normative use of tobacco as barriers to quitting in pregnancy and the need for evaluations of interventions at the family and community level. Socioeconomic disparities underscore the importance of enhancing the implementation and reach of strategies to prevent and reduce prenatal tobacco smoking among Indigenous women. Elders and community health care providers as role models for nontobacco use could be explored. Qualitative work is needed to understand the barriers and opportunities, such as cultural strengths supporting quitting tobacco to develop more effective approaches. CONCLUSIONS: Although a high-priority group, there remains a dearth of research on Indigenous women's smoking in pregnancy. Studies have assessed knowledge and attitudes to smoking in pregnancy, and small feasibility studies and a few empirical trials have been conducted. Recommendations for promising culturally appropriate cessation interventions have been made. Larger trials are warranted. IMPLICATIONS: Strategies to support quitting among pregnant Indigenous women need to be multifactorial and take account of the social determinants of smoking including historical antecedents, community norms, cultural strengths, and recognition of individual and community needs. Cross-country research collaborations have the potential to leverage funding, share expertise, and strengthen approaches to tackle an important and poorly attended health disparity that has a profound impact on the entire life course for Indigenous peoples.

An innovative team-based weightloss competition to reduce cardiovascular and diabetes risk among Maori and Pacific people: rationale and method for the study and its evaluation.

BACKGROUND: Obesity rates for New Zealand (NZ) Pacific and Maori (NZ indigenous people) are among the highest in the world. Long-term results of weight management programmes for adults have been modest but primarily focused on individuals. This paper describes the rationale and methodology for a trial of a culturally tailored team-based weightloss competition conducted online with community level support. METHODS/DESIGN: A quasi-experimental design was used to compare an intervention and control group. Three six-month competitions with seven teams of seven Maori or Pacific people (N = 147) were run. Eligible participants were: Maori or Pacific, 16 years of age and above, obese (BMI ≥30 kg/m2) and either at risk of or already diagnosed with type 2 diabetes (HbA1c >50 mmol/mol) or cardiovascular disease.The intervention facilitated group use of an internet-based competition offering financial incentives, education and support. The primary outcome was percentage of individual weight lost at 12-months. Secondary outcomes were percentage reduced total cholesterol and glycated haemoglobin (HbA1c). Data collected at baseline, 6-months and 12-months included: height, body weight, blood lipids and HbA1c, eating and dieting habits, family support, food access, alcohol use, nutrition literacy, activity levels, perceptions of weight, stress and sleep, and, perceived contagion effect. Process evaluation tasks will inform acceptability. DISCUSSION: An attractive, easy to understand weight change programme that effectively reduces disease risk among Maori and Pacific is desperately needed. Web-based delivered support and information to largely self-directed teams could also ease exponential rises in costs to the health system. TRIAL REGISTRATION: Trial Id: ACTRN12617000871347.

Recruiting Pregnant Indigenous Women Who Smoke into a High Contact Incentivized Cessation Trial: A Feasibility Study.

INTRODUCTION: Smoking prevalence among pregnant indigenous women is disproportionately higher than for nonindigenous pregnant women. Incentives have been shown to increase retention in and the effectiveness of smoking cessation programs. To trial if this could work for indigenous women, we aimed to recruit and observe retention of Maori (New Zealand indigenous people) pregnant women that smoke into a cessation program using incentives. METHODS: A parallel group, randomized controlled feasibility trial was undertaken in New Zealand. Pregnant Maori women who smoked were recruited through health practitioners, social media, and general media advertising. Outcomes included ease of recruitment, enrollment rate, retention, cost, and time and distance traveled to visit participants. RESULTS: Seventy-four women were referred for the trial over 7 months. The highest enrollment rate was among self-referrals from media (6 of 10), then women referred from cessation providers (47%, 8 of 17). About three-quarters of women referred from health professionals did not enroll. Only 32% (24) were randomized. Nine women completed the intervention, three withdrew, and 12 were lost to follow-up. On average, it took less time to contact abstinent participants (29 vs. 43 minutes for nonabstinent women). No deception was noted. CONCLUSIONS: Recruitment was difficult and varied by source of first contact. Once enrolled, it was feasible to maintain intensive contact with participants who stayed engaged. The number lost to follow-up was high. We concluded that the tenor of trial promotion could have influenced recruitment and retention rates. Further research with indigenous women is needed to identify better recruitment and retention methods. IMPLICATION: With the rising cost of research and the increased competition for funds, it is important to have evidence that intervention studies with minority group pregnant women who smoke are feasible. Maintaining contact with participants seemed feasible, but the tenor of trial promotion and type of recruitment strategy could influence enrollment and retention of sufficient numbers of participants. Nonjudgmental supportive advertising and invitations direct to women may work better than relying on health professionals as recruiters.

Could 'Aunties' Recruit Pregnant Indigenous Women Who Smoke Into a Trial and Deliver a Cessation Intervention? A Feasibility Study.

Objective Maori (indigenous New Zealand) women have the highest smoking prevalence rates in New Zealand and whilst pregnant. We hypothesized that community health workers ('Aunties') could find pregnant Maori women who smoke, recruit them into a study and deliver an acceptable cessation intervention. The aim of the study was to test the feasibility of such an intervention. Method A community health organization was engaged to, using a participatory approach, conduct a feasibility study. Participants were ten Aunties and the pregnant women the Aunties recruited. The Aunties advised their participants to abstain from smoking, offered a Quitcard (for subsidized nicotine replacement) or referral to local cessation providers. A booklet on healthy eating for pregnancy was given and discussed and the Aunties offered help if needed to register with a lead maternity carer (LMC). All women completed a baseline questionnaire. Semi-structured follow up face-to-face interviews were conducted with a subsample of women and hospital birth records were examined. Descriptive statistics were produced using quantitative data. Qualitative data was deductively analysed. Results During 4 months eight Aunties recruited 67 pregnant women who smoked, 88 % were Maori, 84 % were of low socio economic status and 73 % had up to high school education. Only 36 % of the recruited women had registered with an LMC. The participants described the Aunties as supportive, nice and non-judgmental. The only criticism was a lack of follow up. Aspects of the intervention that the Aunties thought worked well were knowing and being involved with their community, and being able to give a gift pack to the participating women. Insufficient follow up was one aspect that didn't work well. The infant's birth record was found for 54 % of the participants. Conclusion Aunties were able to identify and recruit pregnant Maori women who smoked. The study method and intervention were acceptable to Aunties and participants and it was feasible to collect data from the participants' hospital birth records. Based on this study, with a similar number of Aunties recruiting, it would take 2 years to recruit over 300 participants, which would be sufficient for a stronger controlled trial.

Enlisting "Aunties" to Support Indigenous Pregnant Women to Stop Smoking: Feasibility Study Results.

INTRODUCTION: Smoking during pregnancy increases the risk of many pregnancy and birth complications. New Zealand's smoking cessation programmes rely on the smoker to take action and are embedded within New Zealand's health care. This article describes the smoking behavior outcomes of a feasibility project testing a proactive approach, utilizing Maori voluntary community health workers to identify and reach Maori pregnant women who smoke and provide cessation support. METHODS: Women, who smoked while pregnant, were identified and recruited by "Aunties" and cessation support was provided. Baseline and follow-up interviews were conducted. Outcome measures included smoking status, cigarettes smoked per day, time until first cigarette, cessation attempts during pregnancy, household smoking, and smoking inside the home or car. Simple descriptive statistics were produced and simple proportions reported. RESULTS: The majority of women were Maori, 20-30 years old, had their first cigarette within 30 minutes of waking and 58% had not tried to quit during the current pregnancy. Of the participants who completed a follow-up interview 33% had stopped smoking while they were pregnant and 57% had cut down. There was an increase at follow-up of people who had used cessation support or products. CONCLUSIONS: Aunties are well-placed to find pregnant women and provide cessation support and referral in a way consistent with traditional Maori knowledge and practices. This study suggests such an intervention could increase quit attempts and increase use of effective cessation methods. A more robust study is warranted to develop an enhanced Aunties intervention.

Australian and New Zealand Indigenous mothers' report respect for smoking bans in homes.

BACKGROUND: There is limited data about the reasons behind residential rules to reduce environmental tobacco smoke (ETS) exposure or the establishment or enforcement of such rules in Indigenous populations. AIM: We aimed to gain an understanding of smokefree rules around Australian and New Zealand (NZ) Indigenous infants. METHOD: This was a qualitative study nested within a randomised controlled trial that aimed to test the efficacy of a family-centred tobacco control programme about environmental tobacco smoke (ETS) to improve the respiratory health of Indigenous infants in Australia and New Zealand. Qualitative semi-structured interviews were conducted with 26 Indigenous mothers of infants in Australia (n=7) and NZ (n=19). We asked about the presence of smokefree rules, who set the rules, how the rules were set and enforced, and presence of smokefree rules in participants' wider social circle. Interviews were audiotaped, transcribed, and inductively analysed to identify key themes. FINDINGS: Sixty-nine percent of mothers had partners, 77% smoked and all reported some presence of smokefree rules for house and car. Three main themes were identified: strategies to minimise exposure to ETS, establishing smokefree rules in homes and cars, and, adherence and enforcement of smokefree rules. Several strategies were identified to limit children's exposure to ETS, including rules to limit exposure to third-hand smoke. Mothers extended their smokefree rules to apply to other people's houses or cars, and reported that their family and social circles also had smokefree rules. The main reason for having smokefree rules was for the health of their children. Rules were most commonly set by the mother, often jointly with their partner. Few mothers reported challenges or problems with other people adhering to the smokefree rules. CONCLUSION: Women tried very hard to, and believed that they were effective in, protecting their children from the harmful effects of ETS exposure. In this context, health professionals need to emphasise smoking cessation in parents, so that children are maximally protected from ETS exposure.

Using incentives to encourage smoking abstinence among pregnant indigenous women? A feasibility study.

Smoking during pregnancy increases the risk of many adverse health outcomes for both the mother and the unborn child (Morton et al. 2010). Indigenous people often have a higher smoking prevalence during pregnancy than non-Indigenous populations. In New Zealand (NZ), the smoking rates among Indigenous Maori women who are pregnant have reduced since 1991 (68 %) but still remains high in 2007 (34 %) (Morton et al. 2010). The success rate of most smoking cessation interventions for pregnant smokers is low at <6 % (Lumley et al. 2009). In other populations of pregnant women, financial incentives have been shown to increase the attractiveness of smoking cessation programs and increase the number of quit attempts. A feasibility study was undertaken to determine the likely effectiveness of an incentives-based cessation trial among pregnant Maori women that smoked. Pregnant smokers, aged 16 years and older, who self-identified as Maori, were 2-30 weeks pregnant, and currently smoked, were recruited through health practitioners, print media, and radio adverts in Auckland, NZ. Participants were randomised to (1) usual cessation support, including information about different cessation products and services, and access to nicotine replacement therapy (control), (2) usual cessation support plus a retail voucher to the value of NZ$25 for each 'abstinent from smoking' week for 8 weeks (voucher), or (3) usual cessation support plus product to the value of NZ$25 for each 'abstinent from smoking' week for 8 weeks (product). Outcomes measures included weekly self-reported and monthly biochemically verified smoking status, and acceptability. Of the 74 referred women, 50 declined involvement in the study and 24 consented and were randomised (eight control, eight voucher and eight to product). The mean age of participants was 25 years old (±2.25). Overall 21 % (n = 5) of the women were abstinent from smoking for at least 6 weeks of the eight, one from the control, six from the product and three from the voucher. Our findings suggest that incentives, in particular a choice of products, may be an effective addition to usual care to increase smoking cessation among pregnant Maori women, which has the potential to improve health outcomes for both the mother and child.

A systematic review of barriers and facilitators to participation in randomized controlled trials by Indigenous people from New Zealand, Australia, Canada and the United States.

ISSUE: Many randomized controlled trials (RCTs) are conducted each year but only a small proportion is specifically designed for Indigenous people. In this review we consider the challenges of participation in RCTs for Indigenous peoples from New Zealand, Australia, Canada and the United States and the opportunities for increasing participation. APPROACH: The literature was systematically searched for published articles including information on the barriers and facilitators for Indigenous people's participation in health-related RCTs. Articles were identified using a key word search of electronic databases (Scopus, Medline and EMBASE). To be included, papers had to include in their published work at least one aspect of their RCT that was either a barrier and/or facilitator for participation identified from, for example, design of intervention, or discussion sections of articles. Articles that were reviews, discussions, opinion pieces or rationale/methodology were excluded. Results were analysed inductively, allowing themes to emerge from the data. KEY FINDINGS: Facilitators enabling Indigenous people's participation in RCTs included relationship and partnership building, employing Indigenous staff, drawing on Indigenous knowledge models, targeted recruitment techniques and adapting study material. Challenges for participation included both participant-level factors (such as a distrust of research) and RCT-level factors (including inadequately addressing likely participant barriers (phone availability, travel costs), and a lack of recognition or incorporation of Indigenous knowledge systems. IMPLICATION: The findings from our review add to the body of knowledge on elimination of health disparities, by identifying effective and practical strategies for conducting and engaging Indigenous peoples with RCTs. Future trials that seek to benefit Indigenous peoples should actively involve Indigenous research partners, and respect and draw on pertinent Indigenous knowledge and values. This review has the potential to assist in the design of such studies.

The WERO group stop smoking competition: main outcomes of a pre- and post- study.

BACKGROUND: One potential promising strategy for increasing smoking cessation for Maori (Indigenous New Zealanders) and New Zealand resident Pacific Island people is Quit and Win competitions. The current uncontrolled pre and post study, WERO (WERO in Maori language means challenge), differs from previous studies in that it aims to investigate if a stop smoking contest, using both within team support, external support from a team coach and cessation experts, and technology, would be effective in prompting and sustaining quitting. METHOD: Fifteen teams, recruited from urban Maori, rural Maori and urban Pacific communities, competed to win a NZ$5000 (about € 3,000, £ 2600) prize for a charity or community group of their choice. People were eligible if they were aged 18 years and over and identified as smokers. Smoking status was biochemically validated at the start and end of the 3 month competition. At 3-months post competition self-reported smoking status was collected. RESULTS: Fourteen teams with 10 contestants and one team with eight contestants were recruited. At the end of the competition the biochemically verified quit rate was 36%. The 6 months self-reported quit rate was 26%. The Pacific and rural Maori teams had high end of competition and 6 months follow-up quit rates (46% and 44%, and 36% and 29%). CONCLUSION: WERO appeared to be successful in prompting quitting among high smoking prevalence groups. WERO combined several promising strategies for supporting cessation: peer support, cessation provider support, incentives, competition and interactive internet and mobile tools. Though designed for Maori and Pacific people, WERO could potentially be effective for other family- and community-centred cultures.

Reducing smoking in pregnancy among Maori women: "aunties" perceptions and willingness to help.

Maori (the indigenous people of New Zealand) women have high rates of smoking during pregnancy and 42 % register with a lead maternity carer (LMC) after their first trimester, delaying receipt of cessation support. We used a participatory approach with Maori community health workers ("Aunties") to determine their willingness and perceived ability to find pregnant Maori smokers early in pregnancy and to provide cessation support. Three meetings were held in three different regions in New Zealand. The aunties believed they could find pregnant women in first trimester who were still smoking by using their networks, the 'kumara-vine' (sweet potato vine), tohu (signs/omens), their instinct and by looking for women in the age range most likely to get pregnant. The aunties were willing to provide cessation and other support but they said they would do it in a "Maori way" which depended on formed relationships and recognised roles within families. The aunties' believed that their own past experiences with pregnancy and/or smoking would be advantageous when providing support. Aunties' knowledge about existing proven cessation methods and services and knowledge about how to register with a LMC ranged from knowing very little to having years of experience working in the field. They were all supportive of receiving up-to-date information on how best to support pregnant women to stop smoking. Aunties in communities believe that they could find pregnant women who smoke and they are willing to help deliver cessation support. Our ongoing research will test the effectiveness of such an approach.

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

BACKGROUND: Maori 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.

Health consequences of tobacco use for Maori--cessation essential for reducing inequalities in health.

AIM: Tobacco use remains the largest preventable cause of death and disease in New Zealand. The aim of this paper was to identify all known health consequences of smoking, including exposure to other people's smoke, focusing on Maori. METHOD: A review of the scientific literature, 'grey' literature, and, Government health data and reports. RESULTS: Smoking has been causally linked with cardiovascular disease (CVD), many cancers, and several respiratory diseases, and, rates are higher for Maori than non-Maori. There are many consequences for smokers loved ones, including, pregnancy and birth complications, SUDI, and increased respiratory infections, cancers and CVD for children and adults. Maori have higher rates of still-birth and SUDI. CONCLUSION: This paper summarises all health consequences, to the smoker and their family. Supporting smoking cessation among Maori, particularly women and parents, may be one of the quickest pathways to health improvements for Maori.

Smoke, smoking and cessation: the views of children with respiratory illness.

OBJECTIVE: To explore the attitudes of Maori (indigenous New Zealanders) and Pacific children with respiratory illness towards smoking, secondhand smoke (SHS) and smoking cessation. METHODS: Forty-one Maori and Pacific children (aged 6-11 years) in New Zealand (NZ) were interviewed about their attitudes towards smoking, how SHS affects them and their respiratory disease, ideas they have about how to reduce SHS exposure, their fears and concerns about smoking, and experience asking parents to quit smoking. The interviews were transcribed and deductively analysed. RESULTS: The children said that SHS made them feel "bad," "angry," "uncomfortable" and "really sick," making them want to get away from the smoke. They were aware that smoking "is dangerous" and that "you could die from it." Many children had fears for smokers around them. The children reported on rules restricting smoking around children: "You're not allowed smoke in the car where babies are." A number of children reported that adults complied with those rules, but some reported that people still smoked around them. The children had experienced people around them quitting and had an awareness of how difficult it is to quit smoking. The most common reason perceived for quitting was concern for children. A lot of the children thought they could ask parents to quit and other suggestions included hiding people's tobacco, and use of smoke-free pamphlets, or signs. CONCLUSIONS: Even young children from low socioeconomic minority groups are aware of the dangers of smoking and SHS, and hold negative views about smoking. Health promotion messages for parents could have more weight if they convey the concerns voiced by children.

Why Maori women continue to smoke while pregnant.

AIM: To investigate why some Maori women continue smoking during pregnancy. METHODS: An exploratory qualitative study was conducted with 60 pregnant Maori women aged from 17-43. A questionnaire was used to guide the interviews. Responses were categorised using Te Whare Tapa Wha (the four-sided house), an Indigenous theoretical framework. RESULTS: The women smoked on average 9 cigarettes per day. Many (45%) were very concerned for their baby's health. The main reasons for quitting were for their own and their baby's health. The majority (77%) reported no smoking-related health problems. All the women lived with at least one other smoker. Over half of the participants (62%) predominantly socialised with people who smoked and nearly all said it was easy to smoke in their socialising and work environments. Partners and mothers were the most common source of support or advice to quit, however, often that support person also smoked. There was a lack of understanding of the harms associated with maternal smoking. CONCLUSIONS: Motivation to quit smoking was low. The women all lived with smokers which reportedly made it harder to quit; most of them lived in a smoky environment, where family, friends and coworkers smoked. This highlights the need to include family in cessation interventions.

The use of the 'rollie' in New Zealand: preference for loose tobacco among an ethnically diverse low socioeconomic urban population.

AIM: To examine the prevalence of and reasons for smoking roll-your-own (RYO) cigarettes in a population of South Auckland adults. METHOD: Cross-sectional survey of the parents of 2,973 children at four South Auckland Intermediate Schools in 2007-2009. RESULT: Just over a quarter (813; 27%) of parents were smokers. Most (82%) were Maori or Pacific peoples (47% and 34% respectively) of whom 47% smoked only factory-made (FM) and 38% smoked only RYO cigarettes. Exclusive RYO smoking was more common among European (53%) than Maori (40%), Pacific (38%) and Asian ethnic groups (23%). The most common reasons for preferring RYO over FM cigarettes were lower cost (50%), lasting longer (42%), and taste (8%). A few chose RYO because they perceived them to be less harmful (5%). CONCLUSION: Reducing the cost benefit of RYO should lessen the potential use of RYOs as an alternative to quitting. Health education campaigns are needed to counter incorrect beliefs surrounding RYO. Such programmes should include awareness in schools, churches and Pacific communities.

Driving kids to smoke? Children's reported exposure to smoke in cars and early smoking initiation.

The health risks associated with second hand smoke (SHS) are well-known. However, little is known about exposure to SHS in cars and risk of smoking uptake. This paper investigates the association between pre-adolescents reported exposure to smoking in cars and prevalence of early stage smoking activity. Data from Keeping Kids Smokefree baseline surveys of students were used to investigate smoking status and reported exposure to smoking in cars. Log binomial regression analyses were used to investigate if reported exposure to SHS in cars was associated with smoking prevalence. 83% of 5676 students invited took part. After controlling for all variables reported exposure to smoking in cars and homes were significantly associated with increased risk of initiated smoking (RR 1.87, 95% CI 1.43-2.44, and RR 1.5, 95% CI 1.13-1.97, respectively). Exposure to smoking in cars was substantially and significantly associated with risk of current smoking (RR 3.21, 95% CI 1.45-7.08). Early smoking uptake is associated with students' reported exposure to smoking in cars which confirms the importance of protecting children from SHS. Smoking in cars is under parental control and therefore modifiable. Moreover, children's reports of SHlS exposure offer a simple way of identifying families who can be targeted for tobacco control interventions.

Publications as an indicator of increased tobacco control research productivity (quantity and quality) in New Zealand.

INTRODUCTION: Tobacco control (TC) research capacity and productivity are critical for developing evidence-informed interventions that will reduce the harmful effects of smoking. The aim of this paper was to investigate New Zealand's (NZ) TC research capacity along with the quantity and quality of publications, following two government initiatives aimed, in part, at improving the quantity and quality of NZ TC research. METHOD: Scopus was searched for articles with at least one NZ author and where the topic was of primary relevance to TC. Publications were organized into two time periods, following the government initiatives, 1993-2003 and 2004-2009. We analyzed the number of publications, publication journals, type of publications, impact (using the impact factor), and authorship. RESULTS: There has been an increase in number and impact of publications and number of authors. The number of publications has increased from an average of 14 (1994-2003) to 38 per year (2004-2009). The number of journals published increased from 64 to 86. The impact during 2004-2009 was almost threefold than in 1993-2003. The number of authors increased from 212 to 345, and the number of authors who had at least one first-authored publication increased from 80 to 124. CONCLUSIONS: These results show an encouraging trend in NZ TC research, with an increase in research productivity, quality, and in research capacity. It is possible that government-initiated and -funded infrastructural support contributed to increasing needed TC research, which supports the worth of such initiatives.
