Chewing gum--facts and fiction: a review of gum-chewing and oral health.
(9/154)
The world market for chewing gum is estimated to be 560,000 tons per year, representing approximately US $5 billion. Some 374 billion pieces of chewing gum are sold worldwide every year, representing 187 billion hours of gum-chewing if each piece of gum is chewed for 30 minutes. Chewing gum can thus be expected to have an influence on oral health. The labeling of sugar-substituted chewing gum as "safe for teeth" or "tooth-friendly" has been proven beneficial to the informed consumer. Such claims are allowed for products having been shown in vivo not to depress plaque pH below 5.7, neither during nor for 30 minutes after the consumption. However, various chewing gum manufacturers have recently begun to make distinct health promotion claims, suggesting, e.g., reparative action or substitution for mechanical hygiene. The aim of this critical review--covering the effects of the physical properties of chewing gum and those of different ingredients both of conventional and of functional chewing gum--is to provide a set of guidelines for the interpretation of such claims and to assist oral health care professionals in counseling patients.

The impact of risk communication depends upon a complex interaction between the characteristics of the audience, the source of the message, and its content. Audience perception of risk is influenced by demographic factors (e.g. age, gender), personality profile, past experience, and ideological orientation. It is also affected by cognitive biases (e.g. unrealistic optimism) and lay 'mental models' of the hazard. For food hazards, the important dimensions of risk are controllability, novelty and naturalness. The source must be trusted for a risk message to be effective. Trust is associated with believing the source is expert, unbiased, disinterested, and not sensationalising. To maximise impact, risk communications must have a content which triggers attention, achieves comprehension and can influence decision-making. It must be unambiguous, definitive and easily interpretable--rarely achievable particularly when risk is shrouded in scientific uncertainty. Risk messages initiate social processes of amplification and attenuation, consequently their ramifications are rarely controllable. (+info)
The power of survivor advocacy: making car trunks escapable.
(11/154)
Survivor advocates are powerful workers for injury prevention. Some of the major prevention successes have been due in large part to their efforts. This case history examines the four year campaign to prevent entrapment in car trunks (or boot) through the routine installation of interior trunk releases. It traces how a life altering event began a cluster of activities leading to product redesign and regulation to prevent injury. The following elements were key: data and the lack thereof, identification of possible solutions, newsworthy tragedies and media advocacy, politics and sympathetic lawmakers, an agency with regulatory authority, manufacturers, and trade associations. Survivors can assist the injury field because the personal and the professional complement each other in advocacy. Public health professionals can assist survivor advocates by sharing research, data and organizational skills, and by helping to secure grants. (+info)
The impact of the Internet on quality measurement.
(12/154)
Consumers are eager for information about health. However, their use of such data has been limited to date. When consumers do consider data in making health care choices, they rely more on word-of-mouth reputation than on traditional quality measures, although this information has not necessarily been readily accessible. The Internet changes the exercise of quality measurement in several ways. First, quality information--including reputation--will be more readily available. Second, consumers will increasingly use it. Third, the Internet provides a low-cost, standard platform that will make it vastly easier for providers to collect quality information and pass it on to others. However, major barriers still stand in the way of public access to quality information on the Internet as well as of having that access actually improve patients' care. (+info)
Sovereign immunity and health care: can government be trusted?
(13/154)
When government provides or arranges for health care, it is held to lower legal standards than private parties are, especially when liability is barred by "sovereign immunity". This paper examines sovereign immunity and its implications for health care quality by comparing private-sector and government accountability in several legal contexts. It then considers whether the law should be changed; the possible relationship between limited government accountability and public mistrust of a larger government role in health care; and the potential role of disparate legal standards if a lower tier of care evolves in government programs.

A seat at the table: membership in federal advisory committees evaluating public policy in genetics.
(14/154)
OBJECTIVES: This study examined who participates in federal government advisory committees regarding public policy in human and medical genetics, what parties they represent, and to what extent the general public is meaningfully represented. METHODS: Analysis focused on 7 federal government documents published from January 1990 to February 1995. Advisors were categorized into 4 groups based on the professional affiliations that were listed in the publications. After a search of several references and data-bases, the study examined whether these individuals also had other affiliations not listed in the government publications. RESULTS: Individuals whose principal affiliations were with academia (n = 32; 44%) or industry (n = 19; 26%) represented nearly three fourths of the sample, followed by government employees (n = 13; 18%) and consumer advocates (n = 8; 11%). At least 16% of the advisors serving on the federal committees, mostly members of academia, had a dual affiliation. CONCLUSIONS: These data indicate that the public has modest representation on key federal advisory committees making policy recommendations regarding human genetics technology and clinical practice and that there is ample room for additional public participation.

Can media advocacy influence newspaper coverage of tobacco: measuring the effectiveness of the American stop smoking intervention study's (ASSIST) media advocacy strategies.
(15/154)
OBJECTIVE: To compare the rate and slant of local tobacco control print media coverage in ASSIST (American stop smoking intervention study) states as compared with non-ASSIST states. METHODS: Local tobacco control policy articles, editorials, and letters to the editors published from 1994 to 1998 clipped from all daily local newspapers in the USA were analysed (n = 95 911). The main hypothesis tested for the existence of an interaction between ASSIST intervention and time. This interaction would represent a change in the difference between ASSIST and non-ASSIST states over the course of the intervention. RESULTS: No evidence of an ASSIST-year interaction was found. However, a main effect for ASSIST was significant for the percentage of articles with the model predicting higher rates of articles for ASSIST states. Similarly the rate of letters to the editor expressing protobacco control views was higher in ASSIST states than non-ASSIST states. No main effects or interactions were found for analyses of percentage of protobacco control editorials. Models controlled for a measure of preintervention tobacco control conditions at baseline. CONCLUSIONS: The presence of an ASSIST main effect should be interpreted with caution because of the quasi-experimental design and the lack of information on article rates before the ASSIST intervention. Nonetheless, these preliminary findings suggest some possible effects of the media advocacy activities of ASSIST when controlling for differences in states' initial tobacco control conditions.

Lessons from tobacco control for advocates of healthy transport.
(16/154)
Many parallels can be drawn between cigarettes and motor vehicles, smoking and car driving, and the tobacco and the auto/oil industries. Those promoting healthy and sustainable transport policies can learn lessons from tobacco control activities over the past 50 years. Evidence-based legislation is more effective than negotiated voluntary agreements between industry and government. Media advocacy is crucial to reframe the issues to allow changes in national policies that facilitate healthier choices. Worthwhile public health policies seen as a threat by multinational companies will be opposed by them but active national and international networks of healthcare professionals, voluntary organizations, charities and their supporters can match the political power of these industries.
