Impact of a telephone helpline for smokers who called during a mass media campaign.
(25/736)
OBJECTIVE: To evaluate the impact of a telephone helpline (Quitline) with additional support (written information) on callers who use the service during a mass media campaign. DESIGN: Telephone recall surveys of callers to the helpline carried out two months and one year after their initial call. SETTING: Telephone helpline. SUBJECTS: Callers to the helpline. MAIN OUTCOME MEASURES: Smoking behaviour change among callers to the helpline at two months and one year. RESULTS: At one year 22% (95% confidence interval (CI) 18.4% to 25.6%) of smokers reported that they had stopped smoking. Assuming that those who refuse to take part in the one year follow up are continuing smokers and a further 20% of reported successes fail biochemical validation, this yields an adjusted quit rate of 15. 6% (95% CI 12.7% to 18.9%) at one year. Among ex-smokers, 41% (95% CI 34.3% to 47.7%) reported that they were still not smoking at one year. The adjusted figure for ex-smokers at one year is 29% (95% CI 23.3% to 34.8%). Of those who resumed smoking 28% were smoking less than they had been initially. Currently Quitline receives around half a million calls in the course of one year, 93% of whom are phoning for themselves. This represents 4.2% of the total population of adults smokers in England. CONCLUSION: The Health Education Authority's advertising campaign was extremely successful in generating calls to the helpline. Very large numbers of smokers from diverse backgrounds, including the key groups highlighted in the UK government's recent proposals on tobacco, called the Quitline, which appeared to be very successful in helping these callers to stop smoking. For a single intervention to reach 4.2% of the total population of adult smokers in England is a major achievement. This makes Quitline a very promising model for public health intervention programs.

Exposure of Japanese school children to smoking-related environmental factors.
(26/736)
Japan has no legal restrictions on cigarette advertising and vending machines. This lack of smoking control measures is a possible contributor to smoking initiation by adolescents. This study was conducted to provide primary data on environmental factors related to smoking, such as cigarette advertising and candy cigarettes, that influence elementary school children in Japan. A cross-sectional survey was conducted with a self-administered questionnaire at two elementary schools in Kitakyushu City, Japan in 1995. Questionnaire sheets were anonymously filled out by 282 elementary school children at school. The effective response rate was 91.5% (128 boys and 130 girls). Over 90% of respondents had seen cigarette advertising on TV, candy cigarettes and cigarette vending machines. Over 75% had at least one smoker in their family. Fewer female children expressed an intent to smoke in the future despite the fact that there were no significant sex differences in smoking-related experiences. Children were higher exposed to cigarette advertising on TV, candy cigarettes, vending machines and family members' smoking. Control of such smoking-related factors in the environment would be crucial to keeping children from initiating smoking behavior. (+info)
Automatic control of a robot camera for broadcasting based on cameramen's techniques and subjective evaluation and analysis of reproduced images.
(27/736)
With the goal of achieving an intelligent robot camera system that can take dynamic images automatically through humanlike, natural camera work, we analyzed how images were shot, subjectively evaluated reproduced images, and examined effects of camerawork, using camera control technique as a parameter. It was found that (1) A high evaluation is obtained when human-based data are used for the position adjusting velocity curve of the target; (2) Evaluation scores are relatively high for images taken with feedback-feedforward camera control method for target movement in one direction; (3) Keeping the target within the image area using the control method that imitates human camera handling becomes increasingly difficult when the target changes both direction and velocity and becomes bigger and faster, and (4) The mechanical feedback method can cope with rapid changes in the target's direction and velocity, constantly keeping the target within the image area, though the viewer finds the image rather mechanical as opposed to humanlike.

The future relationship between the media, the food industry and the consumer.
(28/736)
The relationship between the media, the food industry and the consumer is probably at its lowest point as we start the new millennium. The frequency of food scares appears to be increasing and news reports sometimes seem both sensational and polarised. High profile issues like the development of bovine spongiform encephalopathy in the UK and the dioxin contamination of poultry products in Belgium have undermined consumer confidence in the food industry. The recent genetically modified foods' debate has served to demonstrate the gulf that has grown between the food industry, food safety experts and the public. This is a rift that has been exploited by environmental pressure groups and fuelled by the media. This paper examines some of the underlying causes of the current air of mistrust that seems to exist between the media, the food industry and the consumer. Also, by examining the projected trends in these root causes, it draws some conclusions for the future relationship between the parties involved and suggests some changes that may improve the present situation.

Communicating the threat of emerging infections to the public.
(29/736)
Communication theory and techniques, aided by the electronic revolution, provide new opportunities and challenges for the effective transfer of laboratory, epidemiologic, surveillance, and other public health data to the public who funds them. We review the applicability of communication theory, particularly the audience-source-message-channel meta-model, to emerging infectious disease issues. Emergence of new infectious organisms, microbial resistance to therapeutic drugs, and increased emphasis on prevention have expanded the role of communication as a vital component of public health practice. In the absence of cure, as in AIDS and many other public health problems, an effectively crafted and disseminated prevention message is the key control measure. Applying communication theory to disease prevention messages can increase the effectiveness of the messages and improve public health. (+info)
Supplements: questions to ask to reduce confusion.
(30/736)
Written and oral statements concerning supplements are delivered daily to audiences that span the full spectrum of demographics. Yet the common reaction of these audiences to these statements is that they are receiving mixed messages. One source of this confusion could be greatly reduced if each statement concerning supplements always defined the specific parameters of the studies on which the statement is based. Those receiving information about supplements must be made aware that extrapolation of data for one form of a supplement to predict the result of another form many be harmful to one's health. If a statement concerning a supplement does not clearly define the route of delivery, its matrix, the quantity of compound, the purity of compound, and the physiologic condition of the recipient, the statement should be disregarded by all audiences. If the creators of all types of supplement information define these parameters, and if audiences critically review the information provided, confusion concerning supplements will be reduced. (+info)
Unconventional dentistry: Part I. Introduction.
(31/736)
This is the first in a series of five articles providing a contemporary overview and introduction to unconventional (alternative) dentistry (UD) and correlation with unconventional (alternative) medicine (UM). UD is analogous to and conceptually inseparable from UM. Dentists should learn about UD and UM and be aware of evidence on the safety and effectiveness of treatments and procedures. While being skeptical of promotions, dentists should be able to accept and encompass science-based advances and reject unproven and disproven methods. Incorporating selected unconventional methods with conventional dentistry in selected patients for specific purposes may be useful to both patients and dentists. Improved education in critical thinking, research, science, medicine, behaviour, communication and patient management is needed. (+info)
Tobacco industry tactics for resisting public policy on health.
(32/736)
The tactics used by the tobacco industry to resist government regulation of its products include conducting public relations campaigns, buying scientific and other expertise to create controversy about established facts, funding political parties, hiring lobbyists to influence policy, using front groups and allied industries to oppose tobacco control measures, pre-empting strong legislation by pressing for the adoption of voluntary codes or weaker laws, and corrupting public officials. Formerly secret internal tobacco industry documents provide evidence of a 50-year conspiracy to "resist smoking restrictions, restore smoker confidence and preserve product liability defence". The documents reveal industry-wide collusion on legal, political and socially important issues to the tobacco industry and clearly demonstrate that the industry is not disposed to act ethically or responsibly. Societal action is therefore required to ensure that the public health takes precedence over corporate profits. Recommendations for reducing the political influence of the tobacco industry include the following. Every tobacco company in every market should publicly disclose what it knew about the addictiveness and harm caused by tobacco, when it obtained this information, and what it did about it. The industry should be required to guarantee internationally recognized basic consumer rights to its customers. Trade associations and other industry groupings established to deceive the public should be disbanded. These recommendations should be incorporated into WHO's Framework Convention on Tobacco Control.
