Estimated exposure of adolescents to state-funded anti-tobacco television advertisements--37 states and the District of Columbia, 1999-2003.

The majority of persons who become regular smokers begin smoking during adolescence, making this period critical for preventing tobacco use. Evidence suggests that anti-tobacco mass media campaigns that include paid television advertising reduce youth smoking. With development of anti-tobacco programs in all 50 states during the 1990s, spurred by funding from the 1998 Master Settlement Agreement with major cigarette manufacturers, CDC, and other sources, an increasing number of states instituted anti-tobacco media campaigns. This report summarizes trends in median state estimates for the average number of state-funded anti-tobacco television advertisements to which adolescents aged 12-17 years were exposed per month in 37 states and the District of Columbia (DC) during 1999-2003. The findings indicate that the median state estimate of the number of advertisement exposures per month increased from 0.04 in 1999 to 0.80 in 2002 but declined to 0.63 in 2003. The decline in estimated exposure from 2002 to 2003 is consistent with cutbacks in funding for state tobacco-prevention and -control programs during this period. Reduced exposure to state-funded anti-tobacco advertising might be contributing to the recent lack of substantial change in youth smoking prevalence from 2002 to 2004, which had been declining substantially since 1997. The majority of states need to implement additional measures to ensure that adolescents are adequately exposed to effective paid anti-tobacco advertisements as part of tobacco-prevention activities.

Consumption of sexual dialogue and content on television and adolescent sexual outcomes: multiethnic findings.

The purposes of this study were to examine group differences in sexual media consumption and to explore how well adolescents' sexual attitudes and behavior can be explained by viewing of sexually suggestive dialogue (SD) and explicit sexual content (SC) in television media. Participants were 473 male and female high school adolescents who were racially, economically, and age diverse. Television viewing was coded for SD and SC. Both length of time spent watching SD and SC and explicitness of the SD and SC to which adolescents were exposed were factored into the coding scheme. In this sample, SD and SC consumption varied by subgroup and explained variance in some sexual attitudes and behavior variables but not others, and in some demographic subgroups but not others.

Colour television, an imitation of the human visual system.

Colour television is examined as an attempt to imitate the human visual system in image formation, spectral sensitivities, adaptation, contrast effects, signal processing, signal modulation, signal transmission, and interpretation. Many similarities are found, but where differences occur they are discussed in relation to the differences between visual and television technologies.

Desensitization to portrayals of real-life aggression as a function of exposure to television violence.

In two separate experiments, the hypothesis that exposure to violence in the context of television drama decreases subjects' emotional responsivity to portrayals of real-life aggression was tested. Subjects were shown either an excerpt from a violent police drama or a segment of an exciting but nonviolent volley-ball game before watching a videotaped scene of real aggression. Emotionality was measured by changes in skin resistance which was measured continuously throughout the session. In Experiment 1, subjects were 8- to 10-year-old children and the real aggression was a film of an argument and fight between two preschoolers. In Experiment 2, college students participated and reactions to real aggression were measured while subjects watched scenes from news films of the riots at the 1968 Democratic National Convention. With the exception of adult females, subjects who previously had viewed the aggression drama were less aroused by the scenes of real aggression than were subjects who had seen the control film. Further support for the hypothesis was provided by the finding that for most groups of subjects, the amount of television violence normally viewed was negatively related to responsivity while viewing aggression.

[Representation of relations between television watching and delinquency within the scope of causal analysis models].

The subject of research coucerns causal relationships between variables of consuming home videos and television and different indicators of delinquency ("acceptance of social norms" (NORM-AK), "perceived risk of punishment" (DEL-RISK), "severity of negative consequences" (NEG-VAL), "acceptance of illegitimate means" (ILLEG-M)). Additionally, factors of influence external to media are taken into consideration which are connected with delinquency according to criminologic results, i.e. variables of communication and variables of the family life and the structure of the family. The model is tested by a sample of N = 305 male pupils of a Regensburg vocational school with methods analysing causality ("2-Stage-Least-Square" (2-SLS) and "Latent variables path analysis with partial least squares estimation" (LVPLS)). The 2-SLS-estimates largely confirm the causal relationships supposed in the model. The results are, three significantly positive indirect connections from the preference for violence of home videos to the main indicator of delinquency ILLEG-M (by way of the variables "consumption of home videos" put on the Index, NEG-VAL and DEL-RISK). The direct influence of the preference for violence on television on ILLEG-M is confirmed, whereas the direct path from the popularity of violent video films to ILLEG-M cannot be proved. The LVPLS-results essentially correspond to the relationship shown by 2-SLS; in addition the LVPLS-estimates also confirm direct causal relationships between the latent variables "consumption of violent video films" and "delinquency proneness".

Results of a repeat television-advertised mass screening program for colorectal cancer using fecal occult blood tests.

The results of a 1987 television-advertised colorectal screening program using fecal occult blood tests (FOBT) are compared with the initial 1986 program (results in parentheses). In the 1987 program, 73,508 fecal occult blood test (FOBT) kits were distributed free of charge, of which 63% were returned for analysis (57,000, 53%). Twenty-five percent of persons from the initial screening participated again in the 1987 program: 1,303 or 2.8% of persons had a positive screen (1,165, 3.9%). The predictive value of a positive screen was 23% for an adenomatous polyp and 8% for colorectal cancer (22%, 8%). Seventy-nine percent of the cancers detected were Dukes A or B or carcinoma in situ (78%). In order to promote a more thorough diagnostic work-up in positive screenes, a suggested diagnostic algorithm for the work-up of a positive FOBT was sent to participating physicians. Despite this, 35% of positive screenees had a diagnostic work-up limited to a repeat FOBT, and/or sigmoidoscopy only (32%). In conclusion, television-advertised mass screening programs consistently enroll large numbers of participants. The rate of compliance (percent of kits returned) and the limited diagnostic evaluation of persons with a positive screen appear to be the major factors limiting the success of our screening program.

Field experiments of television violence with children: evidence for an environmental hazard?

The findings from 20 field experiments were examined to determine the short-term effects of viewing aggression-laden television shows on child social behavior. The available literature provides little support for an effect that is peculiar to aggressive content. In fact, although almost all studies showed elevated levels of antisocial behavior following the viewing of similar material, they also revealed similar, and sometimes greater, effects in response to low or nonaggressive fare. These findings are discussed with regard to their clinical relevance for preventive medicine and implications for imposing "wholesome" television programming on child viewers.

Television's influence on children's diet and physical activity.

Understanding the impact of TV on children's diet and physical activity is important for developing strategies to prevent obesity and sedentary lifestyles. Determining parents' perceptions of television's influence on children's dietary intake and physical activity may provide useful information on this important topic. A questionnaire was developed to assess viewing habits and child requests for food and sport items advertised on TV. It was administered to 66 mothers of children, ages 3-8. Foods that children requested because they had seen them on TV paralleled the frequencies with which these foods were advertised on TV. Weekly viewing hours correlated significantly with (a) reported requests by children and purchases by parents of foods influenced by TV, and (b) children's caloric intake. Children's requests for sport items and physical activities were not significantly correlated with the number of hours of TV viewing. It appears from these data that parents perceive that television influences family purchasing patterns through the mechanism of their children's requests.

A television format for national health promotion: Finland's "Keys to Health".

A series of televised risk reduction and health promotion programs have been broadcast in Finland since 1978. The five series of programs were the product of a cooperative effort by Finland's television channel 2 and the North Karelia Project. The series has featured a group of volunteers who are at high risk of diseases because of their unhealthful habits and two health educators who counsel the studio group and the viewers to make changes in health behaviors. The "Keys to Health 84-85" was the fifth of the series and consisted of 15 parts, 35 minutes viewing time each. Results of the evaluation surveys, which are presented briefly, indicate that viewing rates were high. Of the countrywide sample, 27 percent of men and 35 percent of women reported that they had viewed at least three parts of the series. Reported changes in behaviors were substantial among the viewers who had seen several parts of the series and were meaningful, overall, for the entire population. Of the countrywide sample, 7.1 percent of smoking viewers reported an attempt to stop smoking--this number was 3.6 percent of all smokers. The percentages of weight loss among viewers and the total population sample were 3.9 for men and 2.1 for women. The reported reductions in fat consumption were 27.2 percent for men and 15.0 percent for women. The reported effects in the demonstration area of North Karelia were even higher, mainly because of higher viewing rates.

Youth and alcohol in television stories, with suggestions to the industry for alternative portrayals.

The mass media have long been criticized, particularly on the issue of youth and morality. Attempts to intervene with media executives to change the messages are a familiar accompaniment of the criticism. A specific issue is the presentation on television of incidents involving youth and drinking. Numerous relevant scenes, taken from field notes on prime-time television programs starting in the 1976-77 season, are described. They are also evaluated as to their appropriateness with respect to youth and alcohol. Several, but not all incidents are found to be useful to alcohol education for young people, and for adults as well. A series of suggestions for alternative portrayals is presented; these will be disseminated to producers, writers, and directors in the industry.

Autoerotic asphyxial death following television broadcast.

How individuals who engage in autoerotic asphyxial activities first become aware of its purported erotic potential is debated. The case of an adult male who died from autoerotic asphyxiation shortly after watching a television show that discussed sexual asphyxiation is reported. A request is made that medical examiners and coroners report other accidental autoerotic deaths that are temporally associated with this television broadcast.

Health education on the six-o'clock news. Motivating television coverage of news in medicine.

Prepackaged video news releases are being increasingly used to motivate television stations to cover stories in medicine and public health in their news programs. On Feb 26, 1987, the Office on Smoking and Health, US Department of Health and Human Services, distributed a prepackaged video news release to television stations across the country, calling attention to the new health warnings required on smokeless tobacco packages and advertisements. The video was sent by satellite as well as by overnight mail to selected stations. To assess the use of the video, we surveyed 76 stations that had been targeted by special intervention. These stations were in major metropolitan areas in states with a higher prevalence of smokeless tobacco use. Seventeen (22.4%) of the stations aired the story using our video during the six days following the satellite feed, reaching an estimated 2.8 million households. Another 20 stations reported that they were holding the video for use in the near future or for file footage. We conclude that the distribution of prepackaged video news stories can be an effective, relatively inexpensive technique to communicate health information to a large audience.

Reality perceptions of television: a comparison of emotionally disturbed, learning disabled, and nonhandicapped children.

The Stony Brook Videotest (SBV), a measure of reality perceptions of television programs and commercials, was administered to 38 emotionally disturbed (ED), 35 learning disabled (LD), and 159 nonhandicapped elementary school children. The ED and LD children scored significantly lower than the comparison group, indicating that ED and LD children are less able to distinguish between reality and fantasy on television. The clinical implications of these findings and possible remedial actions are discussed.

[Experience in health education of children by televised messages].

A questionnaire was submitted to 394 school children aged from 9 to 12 years following a short campaign of health education using televised advertisements. Slides with a drawing and a brief comment were used and broadcasted on a regional TV network. The results of the survey showed that there is still an important need for health education among children to which television can effectively contribute.

Television choledochoscopy.

Present techniques of intraoperative cholangiography and choledochoscopy have not completely solved the problem of the common bile duct stone that is missed. Televised choledochoscopy provides an improved imaging technique which should facilitate stone retrieval. A similar television endoscopic technique has already become standard among orthopedic surgeons performing diagnostic and therapeutic arthroscopy. This equipment can be shared by surgeons specializing in orthopedic or general surgery.

Annoyance response to spectrally modified recorded aircraft noise during television-viewing.

Magnitude estimations of the annoyance of 27 individual noise stimuli were made by 24 Ss while viewing television; 8 different spectrum modifications of a basic aircraft noise were introduced at 3 overall intensities. The basic spectrum was that of an untreated commercial jet aircraft takeoff noise; the other 8 were created by removal of one of two amounts of energy from an octave band centerered at either .315, .8, 1.6, or 4 kc/s. An ANOVA showed significant annoyance differences for spectrum modification, overall noise intensity and their interaction. Annoyance reduction was greatest when energy was removed at the octave band centered at 1.6 kc/s, next at .8, and .315, and least at 4 kc/s. Although greater overall intensity reduction yielded progressively less annoyance with various spectrally-modified noises as well as unmodified noise, the spectrum modification was apparently most effective in reducing annoyance when the overall maximum noise intensity ranged from 88.0 to 89.1 dbA, and was least effective from 83.9 to 85.3 dbA. Annoyance reduction resulting from spectrum modification at a single octave band (centered at either .8 or 1.6 kc/s) was equivalent to that resulting from a 2.7 dbA overall intensity reduction. The results are discussed in terms of speech interference as well as intermodal effects of noise during television viewing.

[Automated analysis of the cerebral cortex using a television image analyzer].

In the context of the development of approaches to a quantitative automated analysis of neural tissue, the use of television image analyzers seems to be fairly promising. A complex of programmes for the television analysis system (TAS) by "Leitz Company" has been developed to implement an automated analysis of cerebral cortex sections. At the first stage of investigation, the operator sets a plan of scanning the object in the interactive regimen and with a small magnification of the microscope. The second stage involves the focusing and discrimination of images, selection of objects for analysis and measurement of the principal stereological parameters of neurons with a large magnification and at an automatic regimen. The curves obtained of changes of the stereological characteristics of the cortex in relation to the distance to the surface are in good agreement with the cytoarchitectonic pattern observed. Thus, the use of the TAS allows for the effective automated processing of neuromorphological preparations.

Graduate students develop PSAs: a media experience provided by commercial television.

Graduate students in a nutrition education course worked with the special projects producer at a commercial television station to develop three nutrition PSAs. This project involved the students in experiences that demonstrated the possibilities as well as the limitations of using commercial television for defined educational purposes. It was evaluated as a meaningful learning experience by all of the students, and one which will encourage them to work with mass media in their professional careers.
