A study of media effectiveness for sickle cell anemia education in a rural community.

A study was done in Orangeburg County, South Carolina, in order to determine the relative effectiveness of the various mass media (television, radio, and newspaper) in delivering an educational message about sickle cell anemia. The study also focused on different subpopulations. It was found that subpopulations varied in the extent to which they were reached by the message through a given medium. This indicates that any plan for media utilization in a campaign for sickle cell anemia education should take into consideration the subpopulation at which the message is aimed.

Nonprescription drug use among hospitalized pediatric patients.

The parents of pediatric patients were questioned regarding the use and selection of nonprescription drugs for their children. A questionnaire was distributed to the parents of 200 hospitalized pediatric patients. It gathered information on nonprescription drug use during the six-month and one-week periods before hospitalization, the importance of various sources of advice regarding the need to self-medicate, and the sources of product information and the factors influencing product selection. One hundred sixty questionnaires were returned. Almost all of the children (97.5%) were self-medicated by their parents within the six-month period before hospital admission. Only 21% of the parents usually sought advice before deciding to self-medicate their children. Physician recommendations were noted as an important factor in the selection of a nonprescription product, followed an importance by pharmacists and then other health-care professionals. Professional recommendations all ranked higher than other recommendation sources, such as television, radio, or printed advertisements. Pharmacists should take a more active role in aiding parents in their decision to self-medicate their children.

Study of the knowledge, attitude of Egyptian health care workers towards occupational HIV infection.

Acquired immuno-deficiency syndrome (AIDS) was reported for the first time in Egypt in 1986. Up to March 1993, 60 cases were notified to the Ministry of Health and 359 were detected to be infected with human immunodeficiency virus (HIV). Most cases had acquired infection abroad through blood, blood products or sexual contact. The number of cases is continuously increasing. Fear and ignorance about HIV infection causes panic among health care workers (HCWs) whenever a case is discovered and needs medical care. We assessed the knowledge and attitude of 346 HCWs towards the probability of occupational HIV infection using a self administered questionnaire. The sample included physicians, surgeons, nurses, laboratory technicians and ambulance workers. 72.8% of HCWs believed that they are in "great" danger of acquiring AIDS through occupational exposure, whereas 0.6% thought that there was no danger. 67% of HCWs had wrong ideas about transmission of HIV (toilet seats, droplet infection, touching patients). 83.5% mentioned that AIDS patients should be isolated in quarantine. The main source of information about AIDS was the television, radio and ordinary press. 44.8% got their information from textbooks or scientific literature. 95.4% felt the need for more information about infection and disease. The results show an urgent need to start a program of education of HCWs concerning the risk of occupational HIV infection and the measures of its prevention.

Use of peer role models to increase Pap smear and mammogram screening in Mexican-American and black women.

We evaluated the use of a community-based intervention model to increase Pap smear and mammogram screening in minority women. The community programs were based on the A Su Salud (To Your Health) model, which includes the presentation of positive role models in the media and positive social reinforcement by community volunteers. Mexican-American women 40-70 years of age in Corpus Christi, Texas, and black women 40-70 years of age in Galveston, Texas, were targeted. Role models from the target community told their personal stories about cancer screening through local media (television, radio, and newspapers). Volunteers reinforced media messages among the target audience by distributing newsletters. Preintervention and postintervention cross-sectional surveys among the target group measured relative increases in knowledge, attitude, and practice. Pap smear use (past two years) was not substantially improved. Mammogram use (past two years) increased 57% among Mexican-American women (prevalence rate ratio [PRR] = 1.57; 90% confidence interval [CI] = 1.19, 2.08) and 30% among black women (PRR = 1.30; 90% CI = 1.04, 1.63). We demonstrated the feasibility of implementing a peer role model intervention at the local health department level. The improvement in mammogram use among high-risk women is encouraging, but further controlled research is needed to test the effectiveness and cost-efficiency of this approach.

Do anti-smoking media campaigns help smokers quit?

As part of an evaluation of the 1990-91 anti-tobacco media campaign carried out by the California Department of Health Services, a study was conducted among 417 regular smokers who had quit during the period of the media campaign. In brief telephone interviews, all respondents identified up to three events or experiences that had influenced them to quit. In response to uncued questions, 6.7 percent of those interviewed indicated that they had been influenced to quit by an advertisement they had seen or heard on radio, television, or billboards. In response to direct questions about the media campaign, 34.3 percent of the respondents indicated that the media campaign's advertisement had played a part in their decision to quit. Applying the 6.7 percentage to the number of Californians who quit smoking in 1990-91, it can be estimated that for 33,000 former smokers, the anti-tobacco media advertisements were an important stimulus in their quit decision. Multiplying the 34.3 percent by the number of former California smokers who quit in 1990-91, the estimate of former smokers for whom the media campaign's advertisements played at least some part in their decision to quit rises to 173,000 persons. While causal attributions from such investigations should be made with caution, the evidence suggests that the 1990-91 campaign did influence substantial number of smokers in California to quit.

Monitoring the uptake of Hib vaccine in Forth Valley.

Haemophilus influenzae type b (Hib) infection is an important cause of morbidity and mortality among young children in this country. Immunisation against the disease using protein conjugate Hib vaccine was introduced in the United Kingdom on 1 October 1992. To monitor the impact of this new vaccine in the routine childhood immunisation schedule in Forth Valley Health Board area, a survey of the parents of 200 children born during August 1992 was carried out. A total of 163 (82%) parents responded. While most parents had heard of Hib vaccine or of diseases caused by Hib, specific gaps in their knowledge were noted. In particular a substantial minority (31%) were not aware of the role of Hib vaccine in preventing meningitis. Among health professionals who advised parents on immunisation, the most important group identified by parents were health visitors, followed by family doctors. Leaflets produced by the Health Education Board for Scotland also formed an important and valuable source of information for parents, as did television, radio and newspapers. Monitoring the uptake of Hib vaccine in the sample of 200 children revealed a high uptake of the three recommended doses (96%), with only one child receiving no immunisations at all. If this level of uptake is achieved in other areas then the full potential of the new Hib vaccine in preventing infection among young children will be considerable.

Building relationships and resilience in the prevention of youth violence.

Self Enhancement, Inc., is a grassroots, community-service organization working in the most disadvantaged high-risk community in Portland, Oregon. Its violence-prevention program targets middle-school and high-school students by providing classroom and community activities to these young people. These activities are designed to enhance protective factors and build resilience in youths to enable them to attain healthy and productive lives and to resist the threats of gangs, violence, and drugs. RMC Research Corporation works in partnership with Self Enhancement, Inc., to conduct research and evaluation on the effectiveness of its programs. The Self Enhancement, Inc., program works primarily at the individual student and interpersonal relationship levels. Resilience Theory and its culturally specific Relationship Model drive the formulation of specific strategies and activities. Program staff mentor each student through his or her preadolescent and adolescent years, promoting positive, prosocial norms and expectations for behavior through their peer group activities. The Self Enhancement, Inc., program consists of three major components: classroom, exposure, and proactive education. Classroom education focuses on anger management, conflict resolution, and problem solving. Exposure education consists of quarterly field trips to agencies and organizations in the Portland area that deal with the causes and consequences of violence in the community. Proactive education includes newsletters, student-run assemblies and conferences, and radio/ television public service announcements that communicate antiviolence messages. The evaluation plan is a longitudinal matched comparison group designed to assess the outcomes of the violence-prevention program. Key outcomes are protective factors, health-risk behaviors, and academic measures. Standardized assessment instruments (the Individual Protective Factors Index and the Youth Risk Behavior Survey) were administered to all students during winter 1994. The instruments will be readministered during the same period in the following two years of the project. School records were extracted to assess students' attendance and progress through their academic programs. Of the 326 seventh-, eighth-, and ninth-grade students participating in this study, 95% are African Americans and 51% are boys. The prevalence of fighting (56%) during the past 12 months is higher than that among African-American high-school students nationally, but weapon carrying (27%), alcohol use (30%), and marijuana use (18%) are the same or lower than national averages for this group. All baseline indicators are equivalent between the program and comparison groups with the exception of weapon carrying. Program students report carrying weapons more than do their comparison group counterparts. Baseline indicators of violence-related behaviors clearly indicate the need for intervention in this highly disadvantaged, African-American community. Through its historical presence and recent program development efforts, Self Enhancement, Inc., is well positioned to make a difference in the lives of these young people. The equivalence of program and comparison group students on baseline indicators of violence bodes well for an unequivocal assessment of program effectiveness over time.

Recruitment for an efficacy study in chemoprevention--the Concerned Smoker Study.

Efficacy studies are important for the development of long-term cancer prevention strategies. Recruitment aims for a highly motivated group of participants. The Concerned Smoker Study is aimed at smokers with at least a 15 pack-year history and bronchial atypia on sputum sampling Recruitment has been primarily through use of the media. During the first year of randomization 905 potential participants expressed interest. Of these, 80 were eventually randomized. With over 60 participants having completed the study only one has defaulted and compliance with the study protocol has been high. Participants became aware of the study through the following sources: daily newspaper 36.6%, weekly newspaper 16.2%, television 14.9%, radio 13.8%, community television 1.3%, other sources 13.3%. Over 90% of potential participants who initially express interest in such a chemoprevention project may not ultimately be suitable. The population chosen for such studies may not be very representative of the more general population; however, a high degree of compliance can be obtained which will provide valuable information on treatment efficacy.

Adult and childhood leukemia near a high-power radio station in Rome, Italy.

Some recent epidemiologic studies suggest an association between lymphatic and hematopoietic cancers and residential exposure to high-frequency electromagnetic fields (100 kHz to 300 GHz) generated by radio and television transmitters. Vatican Radio is a very powerful station located in a northern suburb of Rome, Italy. In the 10-km area around the station, with 49,656 residents (in 1991), leukemia mortality among adults (aged >14 years; 40 cases) in 1987-1998 and childhood leukemia incidence (eight cases) in 1987-1999 were evaluated. The risk of childhood leukemia was higher than expected for the distance up to 6 km from the radio station (standardized incidence rate = 2.2, 95% confidence interval: 1.0, 4.1), and there was a significant decline in risk with increasing distance both for male mortality (p = 0.03) and for childhood leukemia (p = 0.036). The study has limitations because of the small number of cases and the lack of exposure data. Although the study adds evidence of an excess of leukemia in a population living near high-power radio transmitters, no causal implication can be drawn. There is still insufficient scientific knowledge, and new epidemiologic studies are needed to clarify a possible leukemogenic effect of residential exposure to radio frequency radiation.

Spectral-motion aftereffects and the tritone paradox among Canadian subjects.

The effect of spectral motion on the tritone paradox was investigated by pretesting subjects residing in southwestern Ontario, Canada, on the tritone task, presenting them with a continuous ascending or descending chromatic scale created using Shepard tones, and then retesting them on the tritone task. Results indicated a negative-motion aftereffect that affected the orientation of the pitch class circle. Differential effects of perceived pitch height on the lower portion of the pitch class circle and of adaptation on the upper portion of the pitch class circle were found in the pre- and postadaptation data, respectively. The implications of this dissociation are discussed. In addition, since our subjects lived relatively close to the U.S. border, the experimental pretests allowed us to examine the hypothesis that a canonical American pitch template similar to that found among "Californian" subjects (Deutsch, 1991) is propagated by linguistic influences of media such as television and radio (Ragozzine & Deutsch, 1994). A survey of our subjects indicated that overall, the majority of time engaged in listening to the radio and watching television or movies was spent with American sources. Despite this, and despite the fact that subjects had widely varying language and cultural backgrounds, a tight distribution of peak-pitch classes was found that is indicative of a "British" pitch template (Deutsch, 1991) for every subject tested.

[Leukemia mortality and incidence of infantile leukemia near the Vatican Radio Station of Rome].

Some recent epidemiological studies suggest an association between lymphatic and haematopoietic cancers and residential exposure to high frequency electromagnetic fields (100 kHz-300 GHz) generated by radio and television transmitters. Vatican Radio, a very powerful radio station transmitting all over the world (up to 600 kW) is located in Santa Maria di Galeria, in the northern suburbs of the city of Rome. Electric field measurements in the proximity of the radio station ranged between 1.5 and 25 V/m. In the 10 km area around the station, with 60.182 residents (1999), leukaemia mortality among adults (> 14 years, 40 cases) in the period 1987-98 and childhood leukaemia incidence in the period 1987-99 (8 cases) were evaluated. The analysis (Stone's conditional test) was performed computing observed and expected cases (reference: population of Rome) in 5 bands of increasing radius (2 km width). The risk of childhood leukaemia was higher than expected within 6 km from the station (Standardized Incidence Ratio = 217; 95% Confidence Interval 99-405). Stone's test showed a significant decrease in risk with increasing distance both for male adult mortality (p-value = 0.03) and for childhood incidence (p-value = 0.04). A Score test, showed a significant decrease in risk of childhood incidence as function of the distance. The main limitations of this study are the small number of observed cases and the use of distance as a proxy for RF exposure. Further research will require a systematic campaign of electromagnetic field measurements to allow better assessment of the population exposure.
