Population and age-group trends in weekend sun protection and sunburn over two decades of the SunSmart programme in Melbourne, Australia.

BACKGROUND: In response to the high skin cancer burden in Australia, the multicomponent, community-wide SunSmart programme has worked since 1988 to reduce excessive sun exposure. OBJECTIVE: To examine trends in key sun-protection behaviours and sunburn for the Melbourne population from 1987 to 2007, and examine for the first time patterns of change among age groups. METHODS: Representative cross-sectional weekly telephone surveys of weekend sun protection and sunburn were conducted over 11 of the summers in the period 1987-88 to 2006-07. Trends were analysed for the population and for age groups, adjusting for ambient temperature and ultraviolet radiation, which are environmental determinants of sun-related behaviour and sunburn. RESULTS: The general pattern of trends suggests two distinct periods, one with rapid improvement in behaviours (more sunscreen use, less unprotected body exposure and less sunburn) from 1987-88 to 1994-95, and the second from 1997-98 to 2006-07 with fewer changes in behaviours noted. The age-group analyses showed a similar pattern of change over time across groups, with a few notable exceptions. CONCLUSIONS: The similarity of the pattern of trends among age groups suggests that external influences including the SunSmart programme's activity had a relatively similar impact across the population. Sun-related behaviours continue to be amenable to change. More recent relative stability with some declines in sun protection suggests further intensive campaigns and other strategies may be needed to maintain previous successes and to achieve more universal use of sun protection.

Effects of mass media campaign exposure intensity and durability on quit attempts in a population-based cohort study.

OBJECTIVE: To assess the extent to which intensity and timing of televised anti-smoking advertising emphasizing the serious harms of smoking influences quit attempts. METHODS: Using advertising gross rating points (GRPs), we estimated exposure to tobacco control and nicotine replacement therapy (NRT) advertising in the 3, 4-6, 7-9 and 10-12 months prior to follow-up of a replenished cohort of 3037 Australian smokers during 2002-08. Using generalized estimating equations, we related the intensity and timing of advertising exposure from each source to the likelihood of making a quit attempt in the 3 months prior to follow-up. RESULTS: Tobacco control advertising in the 3-month period prior to follow-up, but not in more distant past periods, was related to a higher likelihood of making a quit attempt. Each 1000 GRP increase per quarter was associated with an 11% increase in making a quit attempt [odds ratio (OR) = 1.11, 95% confidence interval (CI) 1.03-1.19, P = 0.009)]. NRT advertising was unrelated to quit attempts. CONCLUSIONS: Tobacco control advertising emphasizing the serious harms of smoking is associated with short-term increases in the likelihood of smokers making a quit attempt. Repeated cycles of higher intensity tobacco control media campaigns are needed to sustain high levels of quit attempts.

How does increasingly plainer cigarette packaging influence adult smokers' perceptions about brand image? An experimental study.

BACKGROUND: Cigarette packaging is a key marketing strategy for promoting brand image. Plain packaging has been proposed to limit brand image, but tobacco companies would resist removal of branding design elements. METHOD: A 3 (brand types) x 4 (degree of plain packaging) between-subject experimental design was used, using an internet online method, to expose 813 adult Australian smokers to one randomly selected cigarette pack, after which respondents completed ratings of the pack. RESULTS: Compared with current cigarette packs with full branding, cigarette packs that displayed progressively fewer branding design elements were perceived increasingly unfavourably in terms of smokers' appraisals of the packs, the smokers who might smoke such packs, and the inferred experience of smoking a cigarette from these packs. For example, cardboard brown packs with the number of enclosed cigarettes displayed on the front of the pack and featuring only the brand name in small standard font at the bottom of the pack face were rated as significantly less attractive and popular than original branded packs. Smokers of these plain packs were rated as significantly less trendy/stylish, less sociable/outgoing and less mature than smokers of the original pack. Compared with original packs, smokers inferred that cigarettes from these plain packs would be less rich in tobacco, less satisfying and of lower quality tobacco. CONCLUSION: Plain packaging policies that remove most brand design elements are likely to be most successful in removing cigarette brand image associations.

Relation between newspaper coverage of tobacco issues and smoking attitudes and behaviour among American teens.

OBJECTIVE: Geographic variation in youth smoking prevalence suggests that community-level factors influence risk of tobacco use. We examine the extent to which newspaper coverage of tobacco issues is related to youth smoking attitudes and behaviours. DESIGN: We conducted a content analysis of 8390 newspaper articles on tobacco issues from 386 daily newspapers circulating at 5% or more in 2001-3 Monitoring the Future (MTF) survey communities. This resulted in the creation of community level measures of news volume, content and valence. Associations between news and youth outcomes were assessed using logistic regression analyses adjusting for individual, geographic and tobacco policy factors linked to youth smoking and attitudes. SUBJECTS: 98,747 youth participating in the nationally representative school-based MTF annual surveys between 2001 and 2003. MAIN OUTCOME MEASURES: Perceived harm of smoking, perceived peer smoking, disapproval of smoking, smoking within the past 30 days, daily cigarette consumption. RESULTS: In the five months preceding survey administration, newspapers in MTF communities published an average of 11.9 tobacco related articles (range 0-55.7). Each 10-article increase in newspaper volume over the five-month period was associated with increased odds of perceiving great harm from smoking (OR = 1.04, p<0.01) and disapproving of smoking (OR = 1.04, p<0.05) and decreased odds of perceiving most or all friends smoke (0.94, p<0.01) and smoking in the past 30 days (OR = 0.93, p<0.001). No consistent association was found between the content or valence of coverage and youth smoking outcomes. CONCLUSIONS: Gaining and keeping tobacco on the media agenda is an important tool for tackling youth smoking. As volume appears to be the driving factor, media advocacy may be best targeted towards generating events and highlighting issues likely to increase and sustain news attention.

Press coverage of public expenditure of Master Settlement Agreement funds: how are non-tobacco control related expenditures represented?

OBJECTIVE: To examine newspaper reports of Master Settlement Agreement (MSA) allocation decisions outside of tobacco control, focusing on the arguments being put forth in favour of competing claims on MSA funds. The major aims were to identify newsworthy non-tobacco control areas for which MSA funds have been applied and to examine how non-tobacco control spending has been presented through the US press. DESIGN: A qualitative textual analysis was performed on 94 articles taken from a sample of 322 newspapers over a 12 month period (October 2000 through September 2001) that related to the allocation of MSA funds to non-tobacco control causes. Articles were coded for general content areas of MSA allocation as well as for rhetorical and framing devices employed to explain and justify allocation decisions. MAIN OUTCOME MEASURES: (1) Areas of non-tobacco control allocation; (2) rhetorical devices and framing techniques employed in the articles to discuss the allocation. RESULTS: The analysis identified a wide variety of issues for which MSA funds were being appropriated. Three main frames emerged in relation to justifying or appealing for particular spending decisions: (1) funds should be allocated to the needy and/or the deserving; (2) funds should be spent on state development; (3) funds should be put towards helping the state weather a crisis. Claims for each such issue were made using strategies such as presenting the MSA funds as a "windfall", focusing coverage on the merits of the cause rather than the issue of resource allocation, and stressing links between the particular claim and the stated objectives of the MSA. CONCLUSIONS: Press coverage of MSA non-tobacco control spending suggests that the funds have been quickly formulated as fodder for state spending, rather than to support tobacco control efforts. Thus, caution is required in pursuing settlements with the industry where the objective is better funding for tobacco control efforts, particularly in light of the possibility that press coverage of MSA allocation may actually serve as positive publicity for the tobacco industry.

Health-service use by children with asthma over a 6-month period.

OBJECTIVES: The present study aims to describe the use of health services by children with asthma, and examine disease-specific, parental and sociodemographic variables associated with different levels of health-service utilization. METHODS: Parents of 135 children attending an emergency room (ER) completed questionnaires measuring the children's asthma symptoms, and sociodemographic and psychological variables. Parents were contacted monthly for 6 months to document the number of planned and unplanned visits to hospital and community health-care services for asthma. RESULTS: At least one further unplanned visit to the ER was made by 37% of children, while 62% made at least one unplanned visit to a general practitioner (GP). Fifty-five per cent made planned review visits to a GP, 30% to paediatricians and 5% to hospital clinics. After controlling for the level of asthma symptoms, parental anxiety and parental perceptions of children's vulnerability were associated with unplanned GP visits (P = 0.05 and P = 0.01, respectively); a planned review visit and the child being admitted to hospital for the index attack were associated with unplanned ER visits (P = 0.05 and P = 0.004, respectively). CONCLUSIONS: Children with asthma more frequently attend GP services than hospital services for both planned and unplanned asthma management. Different variables predict the unplanned use of GP and ER services. Understanding these differences is imperative if children and families are to make the most effective use of health services.

Effect of restrictions on smoking at home, at school, and in public places on teenage smoking: cross sectional study.

OBJECTIVE: To determine the relation between extent of restrictions on smoking at home, at school, and in public places and smoking uptake and smoking prevalence among school students. DESIGN: Cross sectional survey with merged records of extent of restrictions on smoking in public places. SETTING: United States. PARTICIPANTS: 17 287 high school students. MAIN OUTCOME MEASURES: Five point scale of smoking uptake; 30 day smoking prevalence. RESULTS: More restrictive arrangements on smoking at home were associated with a greater likelihood of being in an earlier stage of smoking uptake (P<0.05) and a lower 30 day prevalence (odds ratio 0.79 (95% confidence interval 0.67 to 0.91), P<0.001). These findings applied even when parents were smokers. More pervasive restrictions on smoking in public places were associated with a higher probability of being in a earlier stage of smoking uptake (P<0.05) and lower 30 day prevalence (0.91 (0.83 to 0.99), P=0.03). School smoking bans were related to a greater likelihood of being in an earlier stage of smoking uptake (0.89 (0.85 to 0.99), P<0.05) and lower prevalence (0. 86 (0.77 to 0.94), P<0.001) only when the ban was strongly enforced, as measured by instances when teenagers perceived that most or all students obeyed the rule. CONCLUSIONS: These findings suggest that restrictions on smoking at home, more extensive bans on smoking in public places, and enforced bans on smoking at school may reduce teenage smoking.

Trends in hospital readmission for asthma: has the Australian National Asthma Campaign had an effect?

OBJECTIVES: To describe patterns of hospital readmission for asthma in South Australia from 1989 to 1996, in relation to implementation of the National Asthma Campaign. DESIGN AND SETTING: A comparison of hospital admissions in South Australia of patients aged between one year and 49 years for three conditions: asthma (or respiratory failure with asthma as an underlying condition) and two control conditions--diabetes and epilepsy. Individuals were identified by Medicare number and date of birth. OUTCOME MEASURES: Hospital readmission within 28 days and within one year. RESULTS: Overall, by 1996, there was a statistically significant decline in the risk of readmission for asthma within 28 days of 18% and within one year of 17% compared with 1989 readmission rates. There were no reductions in the risk of readmission for diabetes or epilepsy, suggesting that the decline in risk of readmission for asthma was greater than the underlying effects of general changes in hospital casemix. CONCLUSIONS: The decline in risk of readmission may reflect changes in asthma severity or improved management practices. However, hospital readmission rates still remain high, and to further reduce readmissions for asthma there is a need to identify factors related to presentation for asthma at accident and emergency departments.

Reported use of asthma management plans in South Australia.

OBJECTIVE: To examine the use of asthma management plans (AMPs) and specific elements of AMPs in a South Australian community. DESIGN: Cross-sectional questionnaire survey by experienced interviewers. PARTICIPANTS AND SETTING: 307 adults with current asthma, confirmed by a doctor, who were among 3001 respondents of a representative sample of 4065 South Australian adults recruited by multistage systematic clustered area sampling for a larger study in March 1995. MAIN OUTCOME MEASURES: Prevalence of reported use of AMPs and of specific elements of AMPs, such as knowledge of trigger factors and having an action plan, and the proportion of adults with asthma receiving what we defined as "good management". RESULTS: 46% reported having an AMP; 63% had discussed trigger factors with their doctors and 39.5% had action plans. 82% had been told the severity of their asthma, and 23.3% were receiving good management. CONCLUSION: Less than half of people with asthma use AMPs, although certain elements within the AMPs are reportedly being used more frequently. More research is required on why AMPs are not more generally used and, more importantly, on what elements within the AMP model are useful and effective for people with asthma and likely to be used by their general practitioners (GPs).

General practitioner attitudes to recall systems for cervical screening.

OBJECTIVES: To document the factors associated with general practitioner (GP) use of Pap smear reminder/recall systems and to canvass options for coordinating these GP-based systems with similar centrally based schemes. METHODS: A questionnaire survey of a random sample of South Australian GPs. RESULTS: 259 (78%) of 334 GPs returned questionnaires. 117 (45.2%) GPs had practice-based reminder/recall systems, with a higher prevalence among metropolitan GPs with a computer and who had been in practice for less than 20 years. 91.9% of GPs reported that the central register would be of some help in ensuring regular cervical screening. 38.2% of the GPs preferred reminder letters from the register to be sent to their practice; 27.8% preferred them to be sent directly to women and 22.8% opted for letters to be sent from the register via the laboratories to their practice. 61.4% of respondents had a method of recording women with abnormal smears and 95.6% of these actively recalled such women. CONCLUSION: Substantial variation exists in the use of practice-based reminder/recall systems among GPs. A central register would assist most GPs by providing a back-up reminder service to follow-up women for cervical screening.

General practitioners and palliative care.

A randomly selected sample of 158 South Australian general practitioners (GPs) were sent a questionnaire which assessed opinions and management practices in the palliative care of terminally ill patients. A total of 117 responses (74%) were received. Most GPs were at least moderately satisfied with the care they were able to give their terminally ill patients, although a substantial number reported difficulties in pain and other symptom control, dealing with relatives' emotional distress and attending to patients' psychosocial needs. There was considerable support for continuing education in these aspects of palliative care. More than half were at least somewhat concerned by opioid side effects and impairment of cognitive function, although opioid dependence was not a concern. Considerable dissatisfaction was expressed with public hospital care for the terminally ill and most felt excluded from decision-making once their patients were admitted. The findings suggest that continuing education is required for GPs and that palliative care should become an integral part of undergraduate education. There is also a need to enhance communication and co-ordination between hospital and community-based services for the terminally ill.

Workplace smoking restrictions, occupational status, and reduced cigarette consumption.

Reductions in workday cigarette consumption among indoor workers subject to different levels of smoking restriction were examined using representative population data for both blue-collar and white-collar workers. Regardless of whether workplace smoking bans were total or applied only to the usual work station, reported workday cigarette consumption was reduced by approximately five cigarettes per day compared with leisure-day consumption. This was in contrast to there being no difference between workday and leisure-day consumption among those who had no ban on smoking at their usual work station. This pattern of findings applied to all occupational-status groups, after controlling for sex and number of cigarettes smoked on a leisure day. These results are discussed with reference to potential public-health benefits and to implications for reduced retail sales of cigarettes.

South Australian hypertension survey. General practitioner experiences with drug treatment.

OBJECTIVE: To investigate prescribing habits, educational approaches and perceived needs of general practitioners in the drug treatment of hypertension. DESIGN, SETTING AND PARTICIPANTS: Of 156 randomly selected South Australian general practitioners 132 responded to a questionnaire survey. MAIN FINDINGS: Diuretics are the most commonly chosen drug for the initial management of uncomplicated moderate hypertension. Equivalent patients aged 45, 60 and 75 years would be prescribed a diuretic as drug of first choice in 41%, 55% and 68% of cases respectively. Despite this, there are wide differences in the choice of initial therapy between individual practitioners. These differences can have a substantial cost impact, given that in Australia the cost of diuretic therapy for one month can be as low as $1.97 compared with $34.08 for standard angiotensin converting enzyme inhibitor therapy for one month. There was also a perceived need, and demand, for patient education materials to assist practitioners in the drug treatment of hypertension.

South Australian hypertension survey. General practitioner knowledge and reported management practices--a cause for concern?

OBJECTIVE: To survey South Australian general practitioners to investigate their knowledge and reported management of patients with hypertension. DESIGN, SETTING AND PARTICIPANTS: Of 156 randomly selected SA general practitioners 132 responded to a questionnaire survey. RESULTS: This survey showed substantial differences between general practitioners in their knowledge about hypertension and in their reported practices for diagnostic levels, investigations to be undertaken once diagnosis had been made, levels at which pharmaceutical treatment should be initiated, at which level treatment was regarded as having attained satisfactory control, and length of time for routine review. There was also a demand for materials to be provided to assist in the management of this important condition. CONCLUSIONS: There is a perceived need for better and more appropriate educational materials and a need for a different approach to try and reduce the reported variability in management of patients with hypertension by general practitioners.

Cognitive and social influences on smoking behaviour during pregnancy.

A random sample of 292 women attending a hospital antenatal clinic for routine care was surveyed concerning smoking behaviour and beliefs about smoking in pregnancy. Among women who continued to smoke during their pregnancy, most had cut down. Many expressed a desire to quit, felt guilty about not being able to do so, but reported that smoking offered important benefits relating to relaxation and mood control. Forty (27.8%) of the 144 women who were smokers at the time they became pregnant had quit during pregnancy. In a multivariate analysis, a nonsmoking household, and being more convinced about the health effects of maternal smoking, were most strongly associated with successful cessation. These 2 variables alone were able to correctly classify 83.8% of women as quitters or continuing smokers. Implications for health promotion programmes and messages are discussed.

"Sick of Smoking": evaluation of a targeted minimal smoking cessation intervention in general practice.

Several smoking intervention studies have been conducted overseas which use a minimal amount of general practitioners' time and are conducted within the constraints of a normal consultation. However, there are no published reports of minimal interventions in Australian general practice. This study reports on 1238 South Australian smokers who were assigned to a non-intervention control group or a group which received firm general practitioner advice to quit smoking plus literature. At one-year follow-up, 7.5% of smokers in the minimal advice group who had quit for six or more months remained non-smokers compared with 3.2% in the control group. If similar analytical procedures had been used in this study as were used in the benchmark study in England in 1979, the quit rate for this study would have been 11.3% in the intervention group, and 4.8% in the control group--a net gain of 6.5%. These results are discussed with regard to widespread implementation in Australian general practice.
