Pr?vention chronischer Krankheiten und Gesundheitsf?rderung Der Beitrag der Verhaltensmedizin

In den vergangenen 50 Jahren konnten große Fortschritte in der Entwicklung und der Umsetzung des verhaltensmedizinischen Wissens über die Gesundheit von Individuen und Populationen erzielt werden. Allerdings kamen Gesundheitsförderung und Krankheitsprävention nicht allen Bevölkerungsschichten in und zwischen den einzelnen Ländern in gleichem Maße zugute. Die Ungleichheit der sozialen, psychischen und körperlichen Gesundheit zwischen den wohlhabendsten und ärmsten Bevölkerungsgruppen ist im Wesentlichen gleichgeblieben oder sogar gewachsen. Das Wissen darüber, wie solche Unterschiede in der Gesundheit entstehen, ist allerdings erst dann von Bedeutung, wenn es dazu verwendet wird, geeignete, langfristige und nachhaltige Präventionsstrategien auf mehreren Ebenen zu erarbeiten. Bei solchen Strategien spielen verschiedene Aspekte der globalen natürlichen ökologischen Umwelt und das Streben nach einer sog. gesundheitserhaltenden Umwelt eine wichtige Rolle. Mit dem wachsenden Einfluss der Globalisierung auf die Gesundheit stellt sich die Frage, welche Folgen jenseits der traditionellen nationalen Grenzen für die Krankheitsprävention und für die Gesundheitsförderung zu erwarten sind. Sie sollte uns anregen, darüber nachzudenken, dass die Verbreitung von wirksamen Interventionen auf institutioneller oder politischer Ebene nicht nur innerhalb eines Landes, sondern auch zwischen verschiedenen Ländern von höchster Wichtigkeit ist. In Anbetracht der global und schnell voranschreitenden ökonomischen und sozialen Veränderungen und des gewaltigen Einflusses von globalen Umweltveränderungen auf die Gesundheit müssen die Bandbreite und die Praxis der Verhaltensmedizin erweitert werden.     

Expanding the traditional user versus non‐user dichotomy amongst ecstasy users

Differences in the drug use characteristics and psychosocial variables in the use and non‐use of ecstasy within 845 16–25 year‐olds in the UK was examined. Based on levels of ecstasy use and intentions, two groups of non‐users (resistant and vulnerable), three groups of users (light, moderate and heavy) and an ex‐user group were identified. It was found that there is predictive utility in this way of expanding the widely employed ‘user versus non‐user’ dichotomy. Resistant non‐users were more likely to be younger, female, and were characterized by lower levels of use of four other drugs (amphetamine, cannabis, cocaine and LSD). Those ‘at risk’ of using ecstasy reported more frequent use of amphetamine, LSD, and cannabis than resistant non‐users. Heavy user groups reported using amphetamine, cocaine and LSD more frequently than all the other groups. Having ecstasy using friends increased the odds of being an ‘at risk’ non‐user or an ecstasy user. Normative influence also differentiated between the three user groups (light, moderate, and heavy). Beliefs about ecstasy use being immoral, ecstasy offers being difficult to resist, ecstasy use making one feel guilty and ecstasy being readily available differentiated between user and non‐user groups. These factors could usefully inform the content of health education materials designed to change ecstasy use. Copyright © 2003 John Wiley & Sons, Ltd.     

how organizations should respond to rape in the workplace

Each year, approximately 51,000 incidents of rape and sexual assault occur in the workplace. If an incident of rape occurs in the workplace, management can adopt several procedures for both the assaulted victim and the organization. First, encourage coworkers to show support for the victim. Second, plan the employee's return to work. Third, provide career and other forms of counseling and assistance for the victim. Fourth, and most important, show concern for the employee. An organization can use a variety of administrative controls and environmental designs as preventive measures to help protect employees from being raped or sexually assaulted in the workplace.     

Are we aware of the external factors that influence our food intake?

OBJECTIVES: This research examines the extent to which people accurately report some of the external influences on their food intake. DESIGN: In two studies, specific factors (the presence and behavior of others) were manipulated in order to influence the amount of food that individuals consumed. MAIN OUTCOME MEASURES: The main outcomes of interest were participants' spontaneously generated explanations for their food intake (Study 1; n = 122), and their ratings of the importance of several potential determinants of food intake (Study 2; n = 75). RESULTS: In Study 1, there was high concordance between the amounts eaten by members of a dyad, but very few participants indicated that they were influenced by their partner's behavior; they instead identified hunger and taste as the primary determinants of intake. Study 2 showed that participants' intake was strongly influenced by the behavior of others, but people rated taste and hunger as much more important influences on their intake. CONCLUSIONS: If external environmental factors influence people's food intake without their awareness or acknowledgment, then maintaining a healthy diet can be a challenge, with long-term consequences for health and well-being.     

Effects of alcohol and marijuana on dynamic visual acuity: I. Threshold measurements

Alcohol and marijuana produce significant dose-related reductions in dynamic visual acuity. Ten subjects participated in a double-blind experiment involving three dose levels of each drug (including placebo). The reduction of DVA produced by alcohol (1.0 ml 95% ethanol/kg body weight) was greater than for marijuana (15 mg Δ-9-tetrahydrocannabinol), and we suggest that this difference was produced by differential oculomotor effects of the two drugs. We have speculated that reduction in DVA under alcohol may be a contributing factor in alcohol-related traffic accidents.
