BACKGROUND: Improving social circumstances (eg, an increase in income, finding a job or moving into a good neighbourhood) may reduce tobacco use, but robust evidence on the effects of such improvements is scarce. Accordingly we investigated the link between changing social circumstances and changing tobacco smoking using repeated measures data. METHODS: 15 000 adults with at least two observations over three waves (each 2 years apart) of a panel study had data on smoking status, family, labour force, income and deprivation (both neighbourhood and individual). Fixed effects regression modelling was used. FINDINGS: The odds of smoking increased 1.42-fold (95% CI 1.16 to 1.74) for a one log-unit increase in personal income among 15-24-year-olds, but there was no association of increased smoking with an increase in income among 25+ year olds. Moving out of a family nucleus, increasing neighbourhood deprivation (eg, 1.83-fold (95% CI 1.18 to 2.83) increased odds of smoking for moving from least to most deprived quintile of neighbourhoods), increasing personal deprivation and moving into employment were all associated with increased odds of smoking. The number of cigarettes smoked a day changed little with changing social circumstances. INTERPRETATION: Worsening social circumstances over the short run are generally associated with higher smoking risk. However, there were counter examples: for instance, decreasing personal income among young people was associated with decreased odds of smoking, a finding consistent with income elasticity of demand (the less one's income, the less one can consume). This paper suggests that improving social circumstances is not always pro-health over the short run; a more nuanced approach to the social determinants of health is required. [ABSTRACT FROM AUTHOR]

Background New Zealand has a goal of becoming a smokefree nation by the year 2025. Smoking prevalence in 2012 was 17%, but is over 40% for M_aori (indigenous New Zealanders). We forecast the prevalence in 2025 under a business-as-usual (BAU) scenario, and determined what the initiation and cessation rates would have to be to achieve a <5% prevalence. Methods A dynamic model was developed using Census and Health Survey data from 1981 to 2012 to calculate changes in initiation by age 20 years, and net annual cessation rates, by sex, age, ethnic group and time period. Similar parameters were also calculated from a panel study for sensitivity analyses. ‘Forecasts' used these parameters, and other scenarios, applied to the 2011-2012 prevalence. Findings Since 2002-2003, prevalence at age 20 years has decreased annually by 3.1% (95% uncertainty interval 0.8% to 5.7%) and 1.1% (−1.2% to 3.2%) for non-M_aori males and females, and by 4.7% (2.2% to 7.1%) and 0.0% (−2.2% to 1.8%) for M_aori, respectively. Annual net cessation rates from the dynamic model ranged from −3.0% to 6.1% across demographic groups, and from 3.0% to 6.0% in the panel study. Under BAU, smoking prevalence is forecast to be 11% and 9% for non-M_aori males and females by 2025, and 30% and 37% for M_aori, respectively. Achieving <5% by 2025 requires net cessation rates to increase to 10% for non-M_aori and 20% for M_aori, accompanied by halving or quartering of initiation rates. Conclusions The smokefree goal of <5% prevalence is only feasible with large increases in cessation rates. [ABSTRACT FROM AUTHOR]

Objective To extend the limited international evidence on youth in-vehicle second-hand smoke (SHS) exposure by examining trends in New Zealand, a country with a national smoke-free goal and indoors smoke-free environment legislation. Methods We tracked exposure rates and explored the associations between in-vehicle SHS exposure and smoking behaviours. In-home exposure was also examined for comparative purposes. Data were collected in annual surveys of over 25 000 year 10 school students (14-15-year olds) for a 7-year period (2006-2012). Questions covered smoking behaviour, exposure to smoking and demographics. Results Youth SHS exposure rates in-vehicle and in-home trended down slightly over time (p<0.0001 for both) with 23% exposed in-vehicle in the previous week in 2012. However, marked inequalities in exposure between ethnic groups, and by school-based socioeconomic position, persisted. The strongest association with SHS exposure was parental smoking (eg, for both parents versus neither smoking in 2012: in-vehicle SHS exposure adjusted OR: 7.4; 95% CI: 6.5 to 8.4). After adjusting for seven other factors associated with initiation, logistic regression analyses revealed statistically significant associations of in-vehicle SHS exposure with susceptibility to initiation and smoking. Conclusions The slow decline in SHS exposure in vehicles and the lack of progress in reducing relative inequalities is problematic. To accelerate progress, the New Zealand Government could follow the example of other jurisdictions and prohibit smoking in cars carrying children. Other major policy interventions, beside enhanced smoke-free environments, will also likely be required if New Zealand is to achieve its 2025 smoke-free nation goal. [ABSTRACT FROM AUTHOR]

Background There is increased interest in the effectiveness and cobenefits of measures to promote walking and cycling, including health gains from increased physical activity and reductions in fossil fuel use and vehicle emissions. This paper analyses the changes in walking and cycling in two New Zealand cities that accompanied public investment in infrastructure married with programmes to encourage active travel. Method Using a quasi-experimental two-group pre-post study design, we estimated changes in travel behaviour from baseline in 2011 to mid-programme in 2012, and postprogramme in 2013. The intervention and control cities were matched in terms of sociodemographic variables and baseline levels of walking and cycling. A face-to-face survey obtained information on walking and cycling. We also drew from the New Zealand Travel Survey, a national ongoing survey of travel behaviour, which was conducted in the study areas. Estimates from the two surveys were combined using meta-analysis techniques. Results The trips and physical activity were evaluated. Relative to the control cities, the odds of trips being by active modes (walking or cycling) increased by 37% (95% CI 8% to 73%) in the intervention cities between baseline and postintervention. The net proportion of trips made by active modes increased by about 30%. In terms of physical activity levels, there was little evidence of an overall change. Discussion Comparing the intervention cities with the matched controls, we found substantial changes in walking and cycling, and conclude that the improvements in infrastructure and associated programmes appear to have successfully arrested the general decline in active mode use evident in recent years.

ABSTRACT:This paper estimates the incidence (all ages) of spinal cord neurological impairment (SCI; traumatic and non traumatic) in New Zealand and describes pre-SCI characteristics and early post-SCI outcomes for participants (16-64 years) in this longitudinal study. Demographic and clinical data on all people admitted to New Zealand's two spinal units (mid-2007 to mid-2009 )were included for the estimate of incidence. Participants in this longitudinal study were asked at first interview about pre-SCI socio-demographic, health and behavioural characteristics, and about post-SCI symptoms, general health status (EQ-5D) and disability (WHODAS 12-item). Age-adjusted incidence rates (95% CI) for European,Maori, Pacific and 'Other' ethnicities were 29 (24-34), 46 (30-64), 70 (40-100) and 16 (9-22) per million, respectively. Interviews with 118 (73%) participants (16-64 years), occurred 6.5 months post-SCI. Most reported bother with symptoms, and problems with health status and disability. Compared with Europeans, the incidence of SCI is high among Maori and particularly high among Pacific people. Six months after SCI, proximate to discharge from the spinal units, considerable symptomatic, general health and disability burden was borne by people with SCI. [ABSTRACT FROM AUTHOR]

Objectives This paper aims to examine ethnic differences in financial barriers to access to prescriptionmedication in New Zealand. Methods Data from SoFIE-Health (wave 3), which is an add-on to the Statistics New Zealand-led longitudinal Survey of Family, Income and Employment (SoFIE) (N¼18 320), were analysed using logistic regression, adjusting for demographic, socioeconomic, health behaviour and health variables. Financial barriers to access to prescription items were measured by the following question: 'In the past 12 months, have there been any times when a doctor gave you a prescription, but you didn't collect one or more of these items because you could not afford the cost?'. Results The odds of deferring buying a prescription at least once during the preceding 12 months because they could not afford the cost of the prescription were greater for Maori and Pacific people than for NZ Europeans (OR 2.98, 95% CI 2.56 to 3.47 vs OR 3.52, 95% CI 2.85 to 4.35). Adjusting for potential confounders attenuated the ORs to 1.31 (95% CI 1.08 to 1.58) for Maori people and to 2.17 (95% CI 1.68 to 2.81) for Pacific people. Deferring buying medications because of cost was also associated with increased odds of poor self-reported health status, high/very high psychological stress and the presence of two or more comorbid conditions. Conclusion Ethnicity plays a critical role in facilitating or impeding access to primary health care. This suggests that policy measures to further reduce financial barriers to buying medication may improve access to care for everyone including Maori and Pacific people and may have positive health implications.

STUDY QUESTION Can one tablet containing aspirin, statin, and blood pressure lowering agents improve adherence and risk factor control compared with usual care of patients at high risk of cardiovascular disease in primary care? SUMMARY ANSWER Fixed dose combination treatment improved adherence to all the recommended drugs, but improvements in clinical risk factors were small and did not reach statistical significance. WHAT IS KNOWN AND WHAT THIS PAPER ADDS Two recent long term trials indicate large improvements in self reported adherence to the recommended drugs and modest improvements in risk factor control in high risk patients receiving fixed dose combination treatment. The main findings of this trial were consistent with those of the earlier trials, and acceptability for this treatment was high among general practitioners and patients. [ABSTRACT FROM AUTHOR]
