Can media advocacy influence newspaper coverage of tobacco: measuring the effectiveness of the American stop smoking intervention study's (ASSIST) media advocacy strategies

OBJECTIVE: To compare the rate and slant of local tobacco control print media coverage in ASSIST (American stop smoking intervention study) states as compared with non-ASSIST states. METHODS: Local tobacco control policy articles, editorials, and letters to the editors published from 1994 to 1998 clipped from all daily local newspapers in the USA were analysed (n = 95 911). The main hypothesis tested for the existence of an interaction between ASSIST intervention and time. This interaction would represent a change in the difference between ASSIST and non-ASSIST states over the course of the intervention. RESULTS: No evidence of an ASSIST-year interaction was found. However, a main effect for ASSIST was significant for the percentage of articles with the model predicting higher rates of articles for ASSIST states. Similarly the rate of letters to the editor expressing protobacco control views was higher in ASSIST states than non-ASSIST states. No main effects or interactions were found for analyses of percentage of protobacco control editorials. Models controlled for a measure of preintervention tobacco control conditions at baseline. CONCLUSIONS: The presence of an ASSIST main effect should be interpreted with caution because of the quasi-experimental design and the lack of information on article rates before the ASSIST intervention. Nonetheless, these preliminary findings suggest some possible effects of the media advocacy activities of ASSIST when controlling for differences in states' initial tobacco control conditions.     

The tobacco settlement: an analysis of newspaper coverage of a national policy debate, 1997-98

OBJECTIVE: To examine the framing of tobacco policy issues in the news media during the national tobacco settlement debate of 1997-98. The major aims were (1) to describe the extent of newspaper coverage of each of the specific components of the proposed tobacco settlement; (2) to identify the tobacco control frames, and the dominant frame, appearing in each newspaper article; and (3) to examine trends in tobacco control frames over time. DESIGN: A content analysis was performed on 117 articles related to national tobacco legislation appearing in the Washington Post from 1 January 1997 through 18 June 1998. MAIN OUTCOME MEASURES: (1) Major policy themes of the settlement referred to or implied in each article; (2) major frames used to discuss the problem of tobacco in each article. RESULTS: The generation of new revenue was the dominant theme of the articles, appearing as a major focus in 44% (52) of the articles. Other than the issues of Food and Drug Administration regulation of tobacco and restrictions on cigarette advertising, the public health policy aspects of the tobacco settlement received little attention. The problem of tobacco was portrayed as one of youth smoking in 55% (64) of the articles, but as one of a deadly product in none of the articles. CONCLUSIONS: Future discussions of comprehensive tobacco policy should be driven by a more specific discussion of the precise programme and policy mechanisms by which tobacco use can be most effectively prevented and controlled. The public health community must find ways to frame the tobacco issue more broadly than simply as one of youth smoking.     

The tobacco industry's code of advertising in the United States: myth and reality

The major American tobacco companies developed and agreed to abide by the Cigarette Advertising Code in 1964. The stated aims of the code were to prohibit advertising directed at young people, to prohibit advertising that used fraudulent health claims, and to assure compliance with the code's provisions through the establishment of an administrative arm and enforcement mechanism to prescreen and monitor all cigarette advertising. In the 32 years since the Cigarette Advertising Code's adoption, the tobacco industry has used the existence of this code and its revisions and promises of self- regulation in accordance with this code as evidence that it promotes tobacco use only in a responsible manner. The code has served as the basis of the industry's efforts to avoid further local, state, and federal regulatory oversight of its marketing activities. A historical review of cigarette advertising since 1964 indicates that the voluntary code's major provisions have been regularly violated in the spirit and the letter. The administrative and enforcement provisions of the original Cigarette Advertising Code were quietly dismantled soon after the voluntary code's adoption and were completely omitted from the revised code in 1990. The historical evidence indicates that self- regulation of cigarette advertising and promotion by the tobacco industry has been repeatedly given trials and has not worked.


     

Filter ventilation and nicotine content of tobacco in cigarettes from Canada, the United Kingdom, and the United States

OBJECTIVES: The purpose was to determine filter ventilation and the nicotine content of tobacco and their contribution to machine-smoked yields of cigarettes from the United States, Canada, and the United Kingdom. METHODS: Ninety-two brands of cigarettes (32 American, 23 Canadian, and 37 British brands) were purchased at retail outlets in State College, Pennsylvania, United States, Toronto, Canada, and London, United Kingdom. A FIDUS FDT filter ventilation tester measured the percentage air-dilution from filter vents. High-pressure, liquid chromatography was used to measure the nicotine content of tobacco. Regression techniques were used to examine the contributions of tobacco nicotine content and filter ventilation to machine-smoked yields of tar, nicotine, and carbon monoxide (CO). RESULTS: Ninety-four per cent of the American brands, 91% of the Canadian brands, and 79% of British brands were ventilated. The total nicotine content of tobacco and percent nicotine (by weight of tobacco) averaged 10.2 mg (standard error of the mean (SEM) 0.25, range: 7.2 to 13.4) and 1.5% (SEM 0.03, range 1.2 to 2) in the United States, 13.5 mg (SEM 0.49, range: 8.0 to 18.3) and 1.8% (SEM 0.06, range: 1.0 to 2.4) in Canada, 12.5 mg (SEM 0.33, range: 9 to 17.5) and 1.7% (SEM 0.04, range: 1.3 to 2.4) in the United Kingdom. Multiple regression analyses showed that ventilation was by far the largest factor influencing machine-smoked yields of tar, nicotine, and CO. CONCLUSION: Filter ventilation appears to be the predominant method for reducing machine-smoked yields of tar, nicotine, and CO in three countries. However, some brands contain about twice as much nicotine (total content or percent nicotine) as do others, indicating that tobacco types or blends and tobacco castings can be used to manipulate nicotine content and nicotine delivery of cigarettes.     

Trends in adolescent smoking initiation in the United States: is tobacco marketing an influence?

OBJECTIVE: To compare recent trends in smoking initiation by adolescents with trends in inflation-adjusted cigarette pricing and tobacco marketing expenditures. DESIGN: We examined smoking initiation trends in demographic subgroups of adolescents aged 14-17 years during the decade 1979-1989. Data on cigarette pricing and tobacco marketing expenditures were adjusted for inflation and plotted over this same period. SETTING: Large population surveys, United States. SUBJECTS: 140,975 ever-smokers aged 17-38 when surveyed in 1992 or 1993, who reported on age of smoking initiation during the decade 1979-1989. MAIN OUTCOME MEASURE: Initiation rate was calculated as the number in an age group who reported starting to smoke regularly in a year, divided by the number of never-smokers at the start of the year. Trends were evaluated by linear and quadratic models. RESULTS: From 1979 to 1984, adolescent initiation rates decreased, but increased thereafter, particularly among males, whites, and those who, as adults, reported never having graduated from high school. Cigarette price increased throughout the decade as did tobacco marketing expenditures, especially for coupons, value-added items, and promotional allowances. CONCLUSION: Availability of cheaper cigarettes is not likely to be a cause of increased smoking initiation by adolescents. Although other influences cannot be ruled out, we suspect that the expanded tobacco marketing budget, with its increased emphasis on tactics that may be particularly pertinent to young people, affected adolescent initiation rates.


     

Impact of the Tobacco Price Support Program on tobacco control in the United States

OBJECTIVES—To evaluate the impact of the United States Tobacco Price Support Program (TPSP) on domestic cigarette consumption and the potential political impact of the TPSP on efforts to reduce smoking.
DATA SOURCES—Published studies known to the authors and a search of AGRICOLA from 1980 to 1996.
STUDY SELECTION—Studies published in a refereed journal or research reports published by an accredited university or institution.
DATA SYNTHESIS—The TPSP decreases cigarette use by increasing the price of cigarettes. The price increase resulting from the TPSP, however, is small—about one cent per pack. The resulting decrease in cigarette consumption is also very modest—an estimated 0.23%. However, the TPSP creates tobacco quota owners, who have a strong financial interest in opposing measures to reduce smoking. The TPSP also changes the political influence of tobacco farmers by keeping a large number of small farmers in tobacco production.
CONCLUSIONS—The negative impact of the TPSP (opposition to tobacco control measures) is probably greater than the positive impact of the programme (reducing smoking). Therefore, the net impact of the TPSP on tobacco control efforts is likely to be negative.

State laws on youth access to tobacco in the United States: measuring their extensiveness with a new rating system

OBJECTIVE: To develop and implement a rating system evaluating the extensiveness of state laws restricting youth access to tobacco. DESIGN: State laws on youth access to tobacco were analysed and assigned ratings on nine items. Six items addressed specific tobacco-control provisions, and three related to enforcement provisions. For each item, a target was specified reflecting public health objectives. Achieving the target resulted in a rating of +4 points; for three items, a rating of +5 was possible if the target was exceeded. Criteria for lower ratings were established for situations when the target was not met. SETTING: United States. RESULTS: State scores (sum of the ratings across all nine items) ranged from 0-18 in 1993, 2-21 in 1994, and 1-21 in 1995 and 1996, out of a possible total of 39. The average score across states was 7.2 in 1993, 7.9 in 1994, 8.2 in 1995, and 9.0 in 1996. The overall mean rating (per item) was 0.80 in 1993, 0.88 in 1994, 0.91 in 1995, and 1.00 in 1996, on a scale where 4.0 indicates that the target goals (per item) were met. From 1993 to 1996, scores increased for 20 states, decreased for one state, and remained unchanged for the others. The number of states for which state preemption of local tobacco regulation was a factor doubled from 10 states in 1993 to 20 states in 1996. CONCLUSIONS: Although all states have laws addressing youth access to tobacco, this analysis reveals that, as of the end of 1996, the progress towards meeting health policy targets is slow, and state legislation that preempts local tobacco regulation is becoming more common.     

Comparing tobacco use among incoming recruits and military personnel on active duty in the United States

OBJECTIVE—To compare the tobacco use profile of recruits with that of military personnel on active duty to determine whether the military environment in some way induces service members to initiate tobacco use.
DESIGN AND SETTING—Cross-sectional survey of United States armed forces active duty and recruit personnel in 1994-95.
SUBJECTS—2711 military recruits and 4603 military personnel on active duty.
MAIN OUTCOME MEASURES—Comparative cigarette smoking and smokeless tobacco use prevalence between recruits and personnel on active duty controlling for age, sex, and race. Impact of demographic factors on the odds of smoking or using smokeless tobacco.
RESULTS—Increases in tobacco use in American military personnel occurred exclusively in men. The highest tobacco use resided with white men on active duty (43% cigarette smoking; 24% smokeless tobacco use) and represents a doubling of tobacco use seen among white male recruits. Among non-white men, tobacco use increased 2-4 times between recruits and personnel on active duty.
CONCLUSIONS—Efforts to reduce tobacco use by American military personnel on active duty should focus more on discouraging the initiation of tobacco use.

Genetic analysis of Holstein cattle populations in Brazil and the United States

Genetic relationships between Brazilian and US Holstein cattle populations were studied using first-lactation records of 305-d mature equivalent (ME) yields of milk and fat of daughters of 705 sires in Brazil and 701 sires in the United States, 358 of which had progeny in both countries. Components of(co)variance and genetic parameters were estimated from all data and from within herd-year standard deviation for milk (HYSD) data files using bivariate and multivariate sire models and DFREML procedures distinguishing the two countries. Sire (residual) variances from all data for milk yield were 51 to 59% (58 to 101%) as large in Brazil as those obtained from half-sisters in the average US herd. Corresponding proportions of the US variance in fat yield that were found in Brazil were 30 to 41% for the sire component of variance and 48 to 80% for the residual. Heritabilities for milk and fat yields from multivariate analysis of all the data were 0.25 and 0.22 in Brazil, and 0.34 and 0.35 in the United States. Genetic correlations between milk and fat were 0.79 in Brazil and 0.62 in the United States. Genetic correlations between countries were 0.85 for milk, 0.88 for fat, 0.55 for milk in Brazil and fat in the US, and 0.67 for fat in Brazil and milk in the United States. Correlated responses in Brazil from sire selection based on the US information increased with average HYSD in Brazil. Largest daughter yield response was predicted from information from half-sisters in low HYSD US herds (0.75 kg/kg for milk; 0.63 kg/kg for fat), which was 14% to 17% greater than estimates from all US herds because the scaling effects were less severe from heterogeneous variances. Unequal daughter response from unequal genetic (co)variances under restrictive Brazilian conditions is evidence for the interaction of genotype and environment. The smaller and variable yield expectations of daughters of US sires in Brazilian environments suggest the need for specific genetic improvement strategies in Brazilian Holstein herds. A US data file restricting daughter information to low HYSD US environments would be a wise choice for across-country evaluation. Procedures to incorporate such foreign evaluations should be explored to improve the accuracy of genetic evaluations for the Brazilian Holstein population.     

Optimized dairy grazing systems in the northeast United States and New Zealand. II. System analysis.

Factors that optimize milk production from Northeast United States and New Zealand grazing systems are compared using a linear programming model. The objective function maximized gross margin per hectare of land farmed. The experimental design compared the optimum characteristics of each system over a range of milk prices. The Northeast has a shorter grazing season and lower cropping costs than New Zealand. The optimum pasture area was 49% of the farm for Northeast systems. Gross margins declined rapidly above 55% or below 36% pasture area. The optimum stocking rate was 1.13 cows/ha, or 2.3 cows/ha of pasture. Optimum per cow production was higher for Northeast [7105 kg of fat-corrected milk (FCM)] than New Zealand (5710 kg of FCM) systems. This was related to lower grain relative to milk prices in the Northeast. New Zealand, all-pasture systems gave the lowest cost per unit of milk but also gave the lowest gross margin across all milk price scenarios. The best use of purchased feed in New Zealand systems was to support increased stocking rate rather than per cow production. Optimum grazing management practices were similar for supplemented New Zealand and Northeast systems. All-pasture New Zealand systems are characterized by short lactations and long autumn rotations to transfer pasture in situ for winter feeding. Higher costs per unit of milk produced will be an inevitable consequence of maximizing gross margin at high milk prices in New Zealand systems.
