The effect of a televised periodontal campaign on public periodontal awareness.

The purpose of this investigation was to evaluate the impact of the Minnesota Dental Association's 1979 to 1980 periodontal awareness television campaign in terms of (1) reaching the target population, (2) improving public knowledge regarding the major reason for tooth loss in adults and (3) increasing intended future preventive dental visits. Based on the Health Belief Model, a 30-second television message was developed presenting periodontal disease as an often overlooked but compelling reason to seek preventive dental care. The message was aimed at adults 18 years of age and older who did not visit the dentist regularly. It was broadcast 1280 times over two separate 6-week periods on 17 statewide television stations. A postcampaign personal interview of a representative cross section of 1,000 Minnesota adults indicated that the campaign reached 79% of the population surveyed, or 786 individuals. Eighty-two percent (534) of the 654 individuals who made regular dental visits and 73% (252) of the 346 individuals who did not, indicated exposure to the message. Of the 786 persons who viewed the message, 90% (707) correctly recalled the message content. Seventy-five percent (488) of the 654 individuals who made regular dental visits and 63% (219) of the 346 individuals who did not, correctly recalled the message content. As a result of exposure to the television campaign, 10% (76) of the 786 viewers indicated their intention to make more preventive dental visits in the future. Among individuals stating such an intention were 10% (71) of the 707 viewers who correctly recalled the message and six percent (5) of the 79 viewers who were not able to correctly recall the message content.

Youth and violence on local television news in California.

OBJECTIVES: This study explores how local television news structures the public and policy debate on youth violence. METHODS: A content analysis was performed on 214 hours of local television news from California. Each of the 1791 stories concerning youth, violence, or both was coded and analyzed for whether it included a public health perspective. RESULTS: There were five key findings. First, violence dominated local television news coverage. Second, the specifics of particular crimes dominated coverage of violence. Third, over half of the stories on youth involved violence, while more than two thirds of the violence stories concerned youth. Fourth, episodic coverage of violence was more than five times more frequent than thematic coverage, which included links to broader social factors. Finally, only one story had an explicit public health frame. CONCLUSIONS: Local television news provides extremely limited coverage of contributing etiological factors in stories on violence. If our nation's most popular source of news continues to report on violence primarily through crime stories isolated from their social context, the chance for widespread support for public health solutions to violence will be diminished.

Diagnosis of breast calcifications: comparison of contact, magnified, and television-enhanced images.

Matched contact and microfocal-spot-magnified images of 31 breasts, each containing a cluster of microcalcifications within a biopsy-proved benign (n = 21) or malignant (n = 10) lesion, were evaluated. Each matched set consisted of one image magnified 1.5 or 2.0 times by a microfocal spot; one contact film-screen mammogram; and one television-digitized, enhanced, and optically magnified contact film-screen mammogram. Three experienced mammographers and three senior diagnostic radiology residents with 2 weeks of training in mammography interpreted the calcifications. The average area under the receiver-operating-characteristic curve for the experienced mammographers was 0.60 for contact radiographs, 0.61 for the television-digitized images, and 0.69 for the microfocal-spot-magnified radiographs. The less experienced senior residents scored below a random choice, 0.44, for the television-digitized images; 0.51 for contact radiographs; and 0.69 for the microfocal-spot-magnified radiographs. We conclude that when evaluating microcalcifications, radiologists without extensive experience in mammography should not substitute television-digitized and enhanced contact mammograms for microfocal-spot-magnified mammograms; rigorous clinical evaluation is needed before this system is accepted for clinical use.

Clinical television microscopy.

The technique of television microscopy is the only available technique for the direct quantitative measurement of skin capillary blood flow. Television microscopy has applications in both research and clinical practice, and has attracted considerable interest from clinical groups attempting to study capillary blood flow. The critical requirements for a functioning system are difficult to ascertain from the published literature. The aim of this article is therefore to describe the individual components of a television microscope system, outline the current methods of analysis and briefly describe some of the clinical applications of television microscopy.

Children and television tipovers: a significant and preventable cause of long-term neurological deficits.

OBJECT: Television tipover has recently been recognized as a significant cause of injury in children, and head injury accounts for most of the associated deaths. The authors reviewed their experience with children who sustained head injury from falling televisions. METHODS: Children admitted with the diagnosis of head injury related to falling televisions since 1992 were identified from the authors' trauma database, and a retrospective review of the medical records was performed. Eighteen patients were identified: 13 boys and five girls whose ages ranged from 12 months to 10 years (mean 44 months). The admission Glasgow Coma Scale (GCS) score was 15 in 10 patients. Only three patients had a GCS score of 8 or less (one patient had a score of 4). Neurological examinations were normal in 10 patients; three had cranial nerve deficits and three had otorrhea, otorrhagia, or hemotympanum. Radiological abnormalities included 16 skull fractures, three epidural hematomas, three small subdural hematomas, one intracranial hemorrhage, and three venous obstructions of the transverse-sigmoid sinus. The mean hospital stay was 8.9 days (range 2-39 days). Follow up at 0.2 to 68 months (mean 13.4 months) revealed severe neurological deficits in one patient and cranial nerve deficits of cranial nerves six, seven, or eight in six patients. CONCLUSIONS: Falling televisions result in significant head injuries in children, with substantial short- and long-term sequelae. This injury is easily preventable through simple measures taken by both the manufacturers and caregivers.

[Superimpose of images by appending two simple video amplifier circuits to color television (author's transl)].

Images are very useful to obtain diagnostic informations in medical fields. Also by superimposing two or three images obtained from the same patient, various informations, for example a degree of overlapping and anatomical land mark, which can not be found in only one image, can be often found. In this paper characteristics of our trial color television system for the purpose of superimposing X-ray images and/or radionuclide images are described. This color television system, superimposing two images in each different color consists of two monochromatic vidicon cameras and 20 inches conventional color television in which only two simple video amplifier circuits are added. Signals from vidicon cameras are amplified about 40 dB and are directly applied to cathode terminals of color CRT in the television. This system is very simple and economical color displays, and enhance a degree of overlapping and displacement between images. As one of typical clinical applications, pancreas images were superimposed in color by this method. As a result, size and position of pancreas was enhanced. Also X-ray image and radionuclide image were superimposed to find exactly the position of tumors. Furthermore this system was very useful for color display of multinuclides scintigraphy.

[Television publicity and food preferences of school age children of the metropolitan region].

BACKGROUND: There is an alarming increase in the prevalence of child obesity in Chile. Lack of exercise and bad feeding habits strongly strongly contribute to the problem. AIM: To investigate the influence of television publicity on school age children food preferences. MATERIAL AND METHODS: A semi structured interview was applied to a representative sample of 786 school age children aged 6 to 11 years old, living in Metropolitan Santiago. Time watching television during week days and the attitude towards food and beverage commercials was analyzed and related to food preferences. RESULTS: Ninety nine percent of school age children watch television during week days and 20% watches more the three hours daily. Snack commercials such as those about potato chips, chocolates, cookies and ice cream, are preferred by 35% of children. Soda commercials are preferred by 33% and yoghurt commercials by 12%. Eighty five percent of children had money to buy food. Of these, 66% bought snacks, 15% bought sodas and 7% yoghurt. The same tendency was observed in school collations. CONCLUSIONS: The high percentage of children, watching television and the influence of commercials in their food preferences, requires an urgent educational strategy to promote healthy feeding habits.

Parents rate the ratings: a test of the validity of the American movie, television, and video game ratings.

BACKGROUND: Numerous studies have documented the potential effects on young audiences of violent content in media products, including movies, television programs, and computer and video games. Similar studies have evaluated the effects associated with sexual content and messages. Cumulatively, these effects represent a significant public health risk for increased aggressive and violent behavior, spread of sexually transmitted diseases, and pediatric pregnancy. In partial response to these risks and to public and legislative pressure, the movie, television, and gaming industries have implemented ratings systems intended to provide information about the content and appropriate audiences for different films, shows, and games. METHODS: We conducted a panel study to test the validity of the current movie, television, and video game rating systems. Participants used the KidScore media evaluation tool, which evaluates films, television shows, and video and computer games on 10 aspects, including the appropriateness of the media product for children on the basis of age. RESULTS: Results revealed that when an entertainment industry rates a product as inappropriate for children, parent raters agree that it is inappropriate for children. However, parent raters disagree with industry usage of many of the ratings designating material suitable for children of different ages. Products rated as appropriate for adolescents are of the greatest concern. The level of disagreement varies from industry to industry and even from rating to rating. CONCLUSIONS: Analysis indicates that the amount of violent content and portrayals of violence are the primary markers for disagreement between parent raters and industry ratings. Short-term and long-term recommendations are suggested.

Television and young Hispanic children's health behaviors.

Television viewing patterns in preschool age Hispanic children were studied in order to explore the role of TV in the establishment of early childhood health behaviors. The television viewing habits and patterns of children and parents and parental coviewing, regulation, and encouragement practices were examined. Using the dimensions of regulation and encouragement, four parental typologies were established: laissez-faire, restrictive, promotive, and selective. Children in this study watched television 3-4 hours a day, half of which consisted of viewing adult shows. This amount of time is significantly higher than the guideline of less than 2 hours a day suggested by the American Academy of Pediatrics (AAP). Relationships between television viewing, injury behaviors, risk taking, and acculturation were established and implications for primary care, school, and community health care nursing are discussed.

[Profile of the Emergency demand and influence of televised soccer games on an extra-hospital center in the Tafalla health care district. Navarre, Spain].

BACKGROUND: The demand placed on both hospital as well as extrahospital emergency care units currently continues to increase at a growing rate. This study has a twofold objective: the quantification and study of the personal characteristics of the users who are demanding emergency care and assessing whether televised soccer games have any bearing on the utilization of emergency care services. METHODS: A longitudinal descriptive study (9,723 users demanding care) and study of cases and controls (1,284 users demanding care) according to whether or not a soccer game was being televised by means of a logistic regression model. The associations were quantified by means of the odds ratio (OR). Those dealt with by telephone or in infirmaries were not included in the study. RESULTS: A total 10.6% of the demand involved home visits, 4.8% of this total having been sent to hospital. A total 13.3% of the demand corresponds to individuals visiting from other healthcare districts, a total of 65 being overusers of emergency care (8 or more visits). The month of August (32.3%). Sundays (44.56%) and the 12:00 p.m.-2:00 p.m. timeframe (8.38%) are the times when the greatest demand for care occurs, the differences being statistically significant. Televised soccer games were associated to a 19.8% (p < 0.001) rise in demand as compared to the control period. CONCLUSIONS: A high degree of use of the extrahospital emergency care units has been found to exist, a major part of the demand being concentrated at highly specific points in time. A major degree of care is provided to those visiting from outside their own healthcare districts. Television soccer game broadcasts is associated with the greater utilization of the emergency care services.

[Children and their television watching habits. A comparative study in rural and urban environments. Considerations on the effects].

In order to establish differences among television watching habits, surveys were conducted in a group of 80 children; 40 from rural areas and another 40 from the urban area, who were attending elementary school at the time. The children were randomly selected; their responses were compared to a national and local listing of television programs, excluding those which were contradictory. Both groups of children spent the same amount of time at school (P = Not significant) while the urban group spent an average of 3.5 hours watching television and the rural group spent 2.3 hours (P = 0.001). Thirty percent of the children from the urban area watched TV with an adult while those from the rural zone were accompanied in 32% (P:NS). The number of television sets per home was significantly greater in the urban areas (P = 0.001). All of the children watched programs which were transmitted after 9 p.m. Both groups chose unneeded food commercials as their favorite programs (P = Not significant).

Violence on television and imitative behavior: impact on parenting practices.

In the past 30 years, four federal government commissions have reported on the relationship between television violence and aggressive behavior. The latest report concluded categorically that there is a causal relationship between television violence and aggressive behavior. Two infants were seen at an emergency room as a direct consequence of their socially isolated single mothers seeing a particular made-for-television movie. In one case, the infant died as a possible result of a parent imitating an act of child abuse; in the other case, early medical intervention precluded possible tragedy. These cases illustrate another way in which children may be victimized by violence on television; namely, by parents imitating inappropriate parental behavior. The origins of imitative behavior are discussed with specific reference to the impact on vulnerable parents. The concept of media-influenced parenting behavior is presented and implications for physicians are discussed.

Television's role regarding alcohol use among teenagers.

The purpose of this study was to determine the extent to which adolescents classified as light, moderate, or heavy television viewers differ regarding alcohol use. The extent to which demographic variables mediate the television-alcohol association also was investigated. A total of 394 high school males completed a written questionnaire to assess television and drinking practices. As hypothesized, heavy viewers consumed alcohol significantly more often than did light and moderate viewers, especially the former, particularly when demographic variables were controlled simultaneously. Television as a powerful and pervasive influence on youth, containing many undesirable health messages, is discussed.

Instructional television graphics.

Instructional television graphics are defined as artwork and photographs used to aid comprehension of a concept presented through the medium of television. In this paper television graphics are examined for educational effectiveness and technical reproducibility. Educational effectiveness of a graphic is facilitated by utilizing the same criteria or components of instructional design used in development of the program. Technical reproducibility is more likely assured if the artist understands the characteristics of television as medium.

HealthScope: a model for a low cost health education program using commercial television.

HealthScope is a health education based on the Health Belief Model that uses television and print materials. It was designed for a number of agendas--(a) a desire by health educators to provide health information to a broad audience at a reasonable cost (b) a desire by the local medical association to promote its role in prevention and primary care, and (c) a desire by commercial television to expand its coverage of local health issues in a cost-effective way. In its summer series, HealthScope included 10 weekly television programs that focused on various aspects of disease prevention and health promotion and answered viewers' questions on the air. Each program was followed by a bank of physicians answering questions on the telephone for 90 minutes. Corresponding fact sheets were distributed through a local pharmacy chain. A "healthy weekend" sweepstakes contest also was held. Intermediate outcome measures indicated that HealthScope had a broad reach and stimulated viewers to seek additional information about health. At the same time, the program generated revenue for the commercial television station.
