The impact of an antismoking media campaign on progression to established smoking: results of a longitudinal youth study.

OBJECTIVES: We examined the impact of a statewide antismoking media campaign on progression to established smoking among Massachusetts adolescents. METHODS: We conducted a 4-year longitudinal survey of 592 Massachusetts youths, aged 12 to 15 years at baseline in 1993. We examined the effect of baseline exposure to television, radio, and outdoor antismoking advertisements on progression to established smoking (defined as having smoked 100 or more cigarettes), using multiple logistic regression and controlling for age; sex; race; baseline smoking status; smoking by parents, friends, and siblings; television viewing; and exposure to antismoking messages not related to the media campaign. RESULTS: Among younger adolescents (aged 12 to 13 years at baseline), those reporting baseline exposure to television antismoking advertisements were significantly less likely to progress to established smoking (odds ratio = 0.49, 95% confidence interval = 0.26, 0.93). Exposure to television antismoking advertisements had no effect on progression to established smoking among older adolescents (aged 14 to 15 years at baseline), and there were no effects of exposure to radio or outdoor advertisements. CONCLUSIONS: These results suggest that the television component of the Massachusetts antismoking media campaign may have reduced the rate of progression to established smoking among young adolescents.

La Esperanza del Valle: alcohol prevention novelas for Hispanic youth and their families.

With extensive Hispanic community involvement, a television, radio, and storybook novela were developed to improve Hispanic parent-youth communications and youth attitudes regarding alcohol. Focus groups with the target audiences determined the novelas' concentration on alcohol, their medium and language of choice for Hispanic youth versus parents, and the health messages and cultural values to be portrayed. Reactions to the novelas were obtained via self-report surveys, random street interviews, radio listener call-ins, and community group meetings. Favorable reactions were obtained regarding the novelas' cultural sensitivity and appropriateness, and their potential to affect future behavior change. The affect of the television novela on Hispanic youth was evaluated by a pre-post self-report survey administered to middle and high school students. Survey results indicated the television novela may have had some positive impact on Hispanic youth attitudes and behavioral intentions regarding alcohol. The evaluation time line was limiting, however, and further evaluation is required.

Bioconverter for upper extremity rehabilitation.

The bioconverter is a simple instrument which uses the output of the Basmajian-Emory myotrainer to activate electrical devices, such as radios, television, etc. It can be used to assist in training by providing an acceptable and/or pleasurable stimulus (such as a radio) as muscle activation improves. The myotrainer contains adjustable sensitivity circuits, and the bioconverter has a pre-set holding circuit of 2, 4, or 6 seconds duration. A case of a deaf and blind patient is presented where the bioconverter is used to activate other sensory (skin) stimuli rather than audio-visual ones. The bioconverter can also be used in relaxation training. In this mode of operation the controlled equipment is on when no EMG is present and is turned off when too high an EMG level exists.

Radio frequency radiation (RFR): the nature of exposure and carcinogenic potential.

Epidemiologic evidence on the relation between radio-frequency radiation (RFR) and cancer is reviewed. Radio-wave communications are used extensively in modern society; thus, we are all subject to RFR created by radio, television, wireless telephony, emergency communications, radar, etc. Interest in the health effects of RFR has been motivated by the rapid growth in wireless communications and by media reports expressing concern that specific diseases may be caused by RFR exposure, e.g., from cellular telephone handsets. Due to the ubiquitous presence of RFR, the public health implication of any connection between RFR and cancer risk is potentially significant. (It is important to keep RFR distinct from power-line electromagnetic fields.) Comparison of potential risks from RFR exposure with other occupational and environmental health risks requires evaluating the level of support from available epidemiology, from studies with laboratory animals, and from mechanistic or biophysical information about the interaction of RFR with living tissues. A large number of studies have been done with laboratory animals and with in vitro systems; a more limited set of epidemiologic studies is available. Effects from RFR exposure that lead to temperature increases have been consistently reported, but 'non-thermal' effects have not been substantiated. Also, there are no mechanistic theories that support 'non-thermal' interactions with biology. Evidence to support a causal relationship between exposure to RFR and human cancers is scant. Our present state of knowledge about exposure, mechanisms, epidemiology, and animal studies does not identify significant cancer risks.

Chemical (VX) terrorist threat: public knowledge, attitudes, and responses.

This article reports the results of a study of people's perceptions and reactions to a hypothetical terrorist attack involving a chemical agent (specifically, the nerve agent VX). Thirteen focus groups composed of 8 to 12 participants each were conducted using trained moderators. To achieve a broad representation of perspectives, the groups were conducted in several regions and included urban and rural locations. In addition, a variety of population groups, such as African Americans, Hispanics, American Indians, Asians, and people with English as a second language, were included in the study. Findings demonstrated fear, fatalism, and unfulfilled information needs related to the threat agent. To better prepare the public for VX threats or threats from other highly toxic chemical agents, it will be important to emphasize that VX exposure can be avoided or reduced, that VX effects can be treated, and that VX can be survived if appropriate protective measures are taken. Related findings from the focus groups are that participants preferred television, radio, and the Emergency Alert System for emergency messages and that people prefer to hear information about a chemical attack from a well-known, well-respected public figure or from a content expert on chemical attacks, protective actions, and health. In addition, local television meteorologists were identified as a category of trusted conveyers of important information in relation to chemical terrorist attacks.

[Effect of mass communication media in food purchasing at the family level].

The main purpose of this study was to determine the effect of mass media advertisement of food products (TV, radio and the press), particularly in pre-school and school-age children, as well as the concomitant impact these age groups have on the family food buying patterns. To test the hypothesis that the impact of mass media advertising on foods varied in the different socioeconomic levels of a community, a stratified sample of all children below 13 years of age, who attended the Francisco Fajardo school in the central coast of Venezuela, was drawn. Mass media contact, food and nutrition knowledge and other socioeconomic characteristics were related to the family's food-buying patterns. More specifically, the age, working status and educational level of the mother in regard to beliefs concerning the nutritional value of advertized food products, were related. A semi-structured questionnaire was designed, tested and applied to the housewife or whoever performed this role within the family. Findings revealed that families of low socioeconomic status are prone to be most influenced by mass media food product advertising. This is reflected not only in food purchasing practices but also in food consumption patterns at the family level. Chocolate drinks, cereals, jello, sausages, and ice cream are the most popular products among pre-school and school-aged children, without social class distinction. Furthermore, results revealed that the degree of exposure to mass communication media--television, radio and newspapers--is a determining factor in children's food preferences at all socioeconomic levels, and that television is the media exerting the greatest influence.

Provider attitudes toward STARPAHC: a telemedicine project on the Papago reservation.

Space Technology Applied to Rural Papago Advanced Health Care (STARPAHC), is a large-scale telemedicine project, sponsored jointly by the Indian Health Service (IHS), NASA, and the Papago tribe, and in operation on the Papago Indian Reservation outside Tucson Arizona, for the past two years. STARPAHC uses a mobile health unit (MHU), staffed by non-M.D. providers and linked by two-way television, radio, and remote telemetry to an IHS hospital up to 100 miles away, to make medical care available in remote areas of the reservation. Over a two-year-period beginning in January, 1975, 47 individual providers, including 21 physicians, were interviewed, at five intervals, to determine their receptivity to and acceptance of telemedicine; because of staff turnover, not all providers were interviewed at each different interval. Data suggests that television equipment was considered costly and in some cases inconvenient to M.D. providers; it was not considered always essential for providers to be able to diagnose and treat patients. The major problems providers cited were the unreliability of equipment and the time required for television consultations. The major benefit cited was improved access to health care for a population not previously receiving such care near their homes. Non-M.D. providers considered the link they were provided to physicians via television and voice communications from remote areas to be a major benefit.

[Method for summing up the radio-frequency electromagnetic fields emitted by several sources].

A method has been developed, included in the BSS 14525-78, for measuring and assessment of the radio-frequency electromagnetic field (EMF) at the working places. In a hygienic assessment of fields, emitted from several sources with different frequencies in one premises, it cannot be applied because of the step frequency relationship of the hygienic norms. The same difficulty is encountered in the hygienic assessment of EMF in settlements, where the summing of the from several radio television and other emitters is necessary. With the non-selective measurements of the intensities of EMF (in a broad-frequency range) in such cases, the resultant field of the working place cannot de resolve into component intensities, obtained from the separate generators and hygienic assessment of the determined value cannot be performed. The same concerns also the cases when we separately measure the radiation from each separate emitter--the summing is impossible. If the electromagnetic waves are discussed as flat waves in the free space, a system of 2m equations with 3 m unknown quantities could be worked out after several approximations, where m is the number of the emitting generators in the premises. Furthermore, if consideration is given to the technical devices for measurement of EMF (type of detector), a system of 2 m equations with so many unknown quantities, could be obtained, hence a mathematical method is proposed for its solving. The expression of the intensities of the field is approximated in a polynomial and an original algorithm is proposed for the solving of the system.(ABSTRACT TRUNCATED AT 250 WORDS)

Effects of alcohol advertising exposure on drinking among youth.

OBJECTIVE: To test whether alcohol advertising expenditures and the degree of exposure to alcohol advertisements affect alcohol consumption by youth. DESIGN: Longitudinal panel using telephone surveys. SETTING: Households in 24 US media markets, April 1999 to February 2001. PARTICIPANTS: Individuals aged 15 to 26 years were randomly sampled within households and households within media markets. Markets were systematically selected from the top 75 media markets, representing 79% of the US population. The baseline refusal rate was 24%. Sample sizes per wave were 1872, 1173, 787, and 588. Data on alcohol advertising expenditures on television, radio, billboards, and newspapers were collected. MAIN EXPOSURES: Market alcohol advertising expenditures per capita and self-reported alcohol advertising exposure in the prior month. MAIN OUTCOME MEASURE: Self-reported number of alcoholic drinks consumed in the prior month. RESULTS: Youth who saw more alcohol advertisements on average drank more (each additional advertisement seen increased the number of drinks consumed by 1% [event rate ratio, 1.01; 95% confidence interval, 1.01-1.02]). Youth in markets with greater alcohol advertising expenditures drank more (each additional dollar spent per capita raised the number of drinks consumed by 3% [event rate ratio, 1.03; 95% confidence interval, 1.01-1.05]). Examining only youth younger than the legal drinking age of 21 years, alcohol advertisement exposure and expenditures still related to drinking. Youth in markets with more alcohol advertisements showed increases in drinking levels into their late 20s, but drinking plateaued in the early 20s for youth in markets with fewer advertisements. Control variables included age, gender, ethnicity, high school or college enrollment, and alcohol sales. CONCLUSION: Alcohol advertising contributes to increased drinking among youth.

Mass media interventions for preventing smoking in young people.

BACKGROUND: The mass media have been used as a way of delivering preventive health messages. They have the potential to reach and to modify the knowledge, attitudes and behaviour of a large proportion of the community. OBJECTIVES: To determine the effectiveness of mass media campaigns in preventing the uptake of smoking in young people. SEARCH STRATEGY: We searched Medline, and 28 other electronic databases. Handsearching of key journals was also carried out, the bibliographies of identified studies were checked for additional references and contact with content area specialists was made. Date of last search June 1998. SELECTION CRITERIA: Randomised trials, controlled trials without randomisation and time series studies that assessed the effectiveness of mass media campaigns (defined as channels of communication such as television, radio, newspapers, bill boards, posters, leaflets or booklets intended to reach large numbers of people and which are not dependent on person to person contact) in influencing the smoking behaviour (either objective or self-reported) of young people under the age of 25 years. DATA COLLECTION AND ANALYSIS: Information relating to the characteristics and the content of media interventions, participants, outcomes and methods of the study was abstracted by one reviewer and checked by a second. Studies were combined using qualitative narrative synthesis. MAIN RESULTS: Six out of a total of 63 studies reporting information about mass media smoking campaigns met all of the inclusion criteria. All six studies used a controlled trial design. Two studies concluded that the mass media were effective in influencing the smoking behaviour of young people. Both of the effective campaigns had a solid theoretical basis, used formative research in designing the campaign messages and message broadcast was of reasonable intensity over extensive periods of time. REVIEWER'S CONCLUSIONS: There is some evidence that the mass media can be effective in preventing the uptake of smoking in young people, but overall the evidence is not strong.

Spontaneous abortions among women employed in the metal industry in Finland.

Spontaneous abortions were analyzed among Finnish metal workers between 1973 and 1976. The information on the workers (35,000 women) was obtained from the files of the Union of Metal Workers; information on the abortions was obtained from the Hospital discharge registry of the National Board of Health. Among metal workers 195 spontaneous abortions were recorded. The proportion of spontaneous abortions was 7.82% (spontaneous abortions/pregnancies, rate) and 13.79% (spontaneous abortions/births, ratio) of which the latter figure was significantly higher (P < 0.05) than the respective one among all Finnish women. Both the rate and the ratio were significantly increased upon joining the Union as analyzed from an age-standardized material. A particular risk industry appeared to be the production of radios, televisions, and their components. An exposure to solder fumes was suggested to explain the increased risk.

[Cardiovascular prevention in the community: the plurisectorial program of the canton of Tessin].

It describes the primary prevention of cardiovascular diseases carried out in Tessin (Italian-speaking Switzerland). Every single action is addressed to the entire population, actively involving professional associations (doctors, pharmacists, nurses, shop-keepers, etc.) and making use in particular of the collaboration of the mass-media (daily press, radio, television). The described actions concern the struggle against the cardiovascular risk factors through the daily diffusion of tv advertisements, free measurement of arterial pressure, and the possibility of disposing in the majority of regional restaurants of a "Health menu" with a low content of saturated fats and cholesterol. In 1984 every citizen of Tessin has been reached by an average of 24 "preventive messages".

Evaluation of mass pulse immunization with oral polio vaccine in Delhi: is pre-registration of children necessary?

Delhi was the fourth State in India to conduct mass immunization of children (Pulse Polio Immunization) of the < 3 year age group with Oral Polio Vaccine (OPV) as a strategy towards the eradication of poliomyelitis. This study attempted to evaluate the immunization coverage achieved and the channels of communication which were effective in increasing coverage in three high risk areas of Delhi during October 1994. The overall immunization coverage was 89%. Information sources like enumeration visits, posters, television, radio and schools statistically correlated with the Pulse Polio Immunization (PPI) outcome. However, the cost of enumeration was high. Other less expensive channels of communication appeared to be equally effective. Only 11% of the children surveyed were not immunized with PPI OPV. The major reasons why some children did not receive OPV was that parents were "not informed" or they were "too busy".

Results of a volunteer program to conduct dietary intervention research for women.

The American Cancer Society (ACS) initiated the Breast Cancer Dietary Intervention Project (BCDIP) to involve community volunteers in cancer-related intervention research activities focused on dietary fat reduction in women with breast cancer. This article presents data on the volunteer aspects of the project, with two aims: (a) to describe the volunteer recruitment and intervention designed for the BCDIP, conducted jointly by the American Cancer Society and the Fred Hutchinson Cancer Research Center, and (b) to present baseline characteristics and predictors of retention of the BCDIP volunteers. There were five types of volunteers, called volunteer adjunct researchers or VARs, in the BCDIP. VARs were recruited using a variety of approaches, including electronic media alerts, flyers in oncology clinics, and notices in the newsletters of state nursing and nutritional professional organizations. Over half of all VARs came from two main sources: the media (television, radio, newspapers) and from work-related sources. Over half (58%) of the VARs had professional licenses in nursing or dietetics, and 46% were employed full-time. Several types of motivations for participating in the BCDIP, including altruistic reasons (want to help others, help people with cancer), health concerns (family/friend with breast cancer, have had cancer), and work-related reasons (gain professional skills) were important. Sixty-eight percent of VARs remained with the project for its entirety. Predictors of retention in the VAR program included previous ACS volunteer experience with initial motivations to volunteer and the interaction of employment status and professional nursing training. In future research and community-based projects, better recruitment and volunteer coordination procedures should be used to reduce dropout rates and maintain volunteer commitment and participation.

Cancer patients seeking information from sources outside the health care system.

Most of the information patients receive about cancer and its treatment is probably provided by staff in health care, but if patients do not get sufficient information there is a risk that they might rely on nonmedical sources to satisfy their need. The aim of this study was to survey the degree to which patients seek information from sources outside the health care system. All adult cancer patients visiting or being admitted to the Oncology Department on 1 day were asked to complete a questionnaire. In the course of that day, 192 adult patients visited the Oncology Department, and the response rate was 74%. The patients had used an active information-seeking strategy, i.e., had sought information from the following sources, only to a limited degree: the Internet (6%) medical books (37%), narratives (32%) and telephone helplines (10%). A more passive information-seeking strategy was more common; the patients obtained information from television and radio (82%), newspapers (86%), other patients (46%) and friends (55%). There was a significant correlation between educational level and information-seeking from the Internet, medical books and telephone helplines. Persons with a higher level of formal education had used these sources more than people with less education (P<0.05). Younger patients (<60 years) and those with a higher level of formal education had greater access to the Internet (P<0.0001) and read about cancer in the papers to a greater degree than older ones (P<0.05). Younger patients (P<0.05) and women (P<0.01) had used narratives to a greater degree than older patients and men. The main finding of this study was that the patients actively sought information about cancer only to a limited degree, but the majority of patients take an interest when cancer issues are presented in newspapers and magazines, or on radio and television.

Survey of patients presenting to the government chest service in Hong Kong and the effects of active tuberculosis case-finding by publicity campaigns. Hong Kong Chest Service/British Medical Research Council.

A previous survey showed that many of the patients diagnosed in a Government chest clinic as new cases of active pulmonary tuberculosis had already attended one or more private practitioners, and that this often resulted in a considerable delay before first attending the Government clinic. Furthermore, outside the Government clinics the standards of investigation, diagnosis and treatment were found to be very variable and patients were, in general, ill informed about the Government chest clinics and the free service they offered. Active case-finding campaigns using television, radio, posters, and leaflets were therefore conducted in 1979 and 1981 and the effects of the campaigns monitored. The aim was to encourage people with a cough which had lasted for a month or more to attend a Government chest clinic for free advice and, if necessary, treatment. In the event, during and immediately after the campaigns there were only minor increases in the numbers of new clinic attenders and of patients with cough, and there were no detectable increases in new cases of tuberculosis. The campaigns failed, in particular, to persuade middle-aged and elderly men with cough and sputum to attend a clinic, although there is evidence that in this group there is a high incidence of tuberculosis requiring treatment.

Hepatitis C in Australia: impact of a mass media campaign.

BACKGROUND: Hepatitis C affects over 200,000 Australians. This study evaluated the impact of a public education campaign about this disease in New South Wales (NSW), Australia. DESIGN: Cohort and independent cross-sectional telephone surveys before and after the campaign. SETTING/PARTICIPANTS: Random population samples of adults in NSW. INTERVENTION: Television, radio and newsprint advertisements, posters and public display boards, public awareness events and media releases, and dissemination of information to healthcare professionals in April 2000. Data were analyzed in 2000 and 2005. MAIN OUTCOME MEASURES: Campaign recall, and knowledge and attitudes concerning hepatitis C. RESULTS: Recall of information about hepatitis C increased between baseline and follow-up, from 11.1% to 45.5% in the independent samples and 11.8% to 65.3% in the cohort. The proportion of people who knew that there was a low risk of disease transmission by kissing, sharing food utensils, or breastfeeding also increased significantly. In the cohort sample, a higher number of correct knowledge responses was associated with reporting exposure to information about hepatitis C after the campaign, postsecondary education, and a greater level of knowledge at baseline. Most people reported supportive attitudes toward people with hepatitis C and to prevention programs addressing this disease, and there was little apparent improvement in these. CONCLUSIONS: This campaign successfully increased public exposure to information about hepatitis C and improved knowledge about the means of transmission of this disease. There is room for further improvements in community understanding about hepatitis C. Mass media campaigns have a valuable role to play in this endeavor.

Impact of a social marketing media campaign on public awareness of hypertension.

BACKGROUND: Barriers to high blood pressure (BP) awareness and control are exacerbated by poor knowledge of the consequences and uncertainty regarding how to and who should direct care. We developed a social marketing hypertension awareness program to determine baseline awareness, knowledge, and treatment behavior, and then studied the impact of a targeted, media intervention among randomly surveyed adults at risk in a representative urban community compared to a control community immediately and 6 months after the intervention. METHODS: The program consisted of three random-digit telephone surveys conducted in two mid-sized Ontario cities to determine high BP awareness, knowledge, and treatment behavior. Using baseline knowledge and attitudes toward high BP in both communities, a social marketing awareness strategy and mass media intervention campaign incorporating television, radio, print, direct to patient, and interactive techniques was developed and implemented in the test city only. Both test and control cities were resurveyed immediately after and at 6 months post-media intervention to detect change and decay. RESULTS: A sample of 6873 men and women more than 35 years old who were aware of their high BP demonstrated a high prevalence of high BP in the general population ( approximately 34% in both communities). At baseline this population had poor knowledge of their own BP numbers and poor understanding of the diseases related to high BP. Although few considered high BP a health concern, they had good understanding of lifestyle interventions for high BP prevention and control. The number of the respondents who claimed to have high BP increased immediately after intervention in the test city (38%; P < .02), whereas the number of respondents who were treated and uncontrolled decreased (P < .05) compared to control. There was a significant increase in patients' knowledge of consequences and in their perception that they were most responsible for high BP control in the test city (P < .005) compared to control. At 6 months, no further changes were observed in those claiming to have high BP in either city, whereas decay to baseline in those treated but not controlled and those claiming responsibility for their BP control was observed in the test city. No changes were observed in the control city accept for an increase from baseline to 6 months in the percentage claiming to be treated but uncontrolled. We were unable to determine whether the increase in number treated but uncontrolled was due to a higher treatment rate, similar treatment rate but more patients being uncontrolled, or a combination of these scenarios. CONCLUSIONS: High BP is very prevalent in adults and knowledge of lifestyle options for management is encouraging. In the short-term, although our media awareness program increased the number of respondents claiming to have high BP and patient self-efficacy for BP control, this was not maintained. We did not change knowledge of consequences or importantly, the health importance of BP control among those at risk. Hence, in addition to a mass media campaign, attention should be focused on dissemination of awareness knowledge information through medical professionals at the point of care.
