OBJECTIVES: HIV/AIDS surveillance methods are under revision as the diversity of HIV epidemics is becoming more apparent. The so called "2nd generation surveillance (SGS) systems" aim to enhance surveillance by broadening the range of indicators to prevalence, behaviors and correlates, for a better understanding and a more complete and timely awareness of evolving epidemics. METHODS: Concepts of HIV SGS are reviewed with a special focus on injecting drug users, a major at-risk and hard to reach group in Europe, a region with mainly low or concentrated epidemics. RESULTS: The scope of HIV/AIDS surveillance needs to be broadened following principles of SGS. Specifically for IDUs we propose including hepatitis C data as indicator for injecting risk in routine systems like those monitoring sexually transmitted infections and information on knowledge and attitudes as potential major determinants of risk behavior. CONCLUSIONS: The suggested approach should lead to more complete and timely information for public health interventions, however there is a clear need for comparative validation studies to assess the validity, reliability and cost-effectiveness of traditional and enhanced HIV/AIDS surveillance systems.
To investigate attrition of subjects in a longitudinal study of caries.
A radiographic study of caries and caries-associated factors was carried out in subjects, initially aged 14 years, and followed-up for six years. Attrition of subjects occurred at the last stage of the study.
A nationwide survey of subjects living in fishing, rural farming, and urban communities in Iceland.
A sub-sample of the nationwide random sample comprising 150 subjects was investigated using bitewing radiographs and a structured questionnaire to determine caries-risk factors. Subjects were re-examined at 16 years and 20 years using the same methods.
Mean caries increment from 14-16 years was 3.0 lesions (1.5 lesions/subject/year) but reduced to 2.6 lesions (0.7 lesions/subject/ year) by 20y. The proportion of subjects found to be caries-free at 14 years, 16 years and 20 years, was 29%, 17% and 10%, respectively. "Dropouts" from this study occurred mostly after 16 years. Analysis of subjects dropping out showed that they were least likely to be from the rural farming community but most likely from the fishing community. Those dropping out attended their dentist less frequently, had a higher consumption of carbonated drinks and a higher prevalence and incidence of caries by 16 years.
Subjects with high-risk behaviours, or residents in a fishing community were more likely to drop out of the study. Recognised advantages of conducting longitudinal studies of caries may, therefore, be lost.
Snowboard injuries in a Swedish ski area were evaluated from 1989 to 1999. All injured skiers (alpine, telemark, snowboarders) who sought medical attention at the local Medical Center within 48 h of the accident, were asked to answer an injury form. Physicians assessed and treated the injured skiers. There were a total of 1775 injured skiers; 568 injured snowboarders mean age 19 years. The female/male ratio was 34/66%, the injury rate 3/1000 skier days, three times higher than that of alpine skiers. The skill level of the injured snowboard riders improved during the period. The fall/run ratio of the beginners was higher (1.0) and their risk behavior lower (3.9 on visual analogue scale 1-10) in comparison to the advanced riders (0.4 and 6.6, respectively). Injuries were in 54% located to the upper extremity, 35% were wrist/lower arm injuries. Beginners had significantly higher frequency of lower arm/wrist injuries (46%), than average (32%) and advanced riders (20%). The most frequent single diagnosis was wrist/lower arm fracture (20%). Advanced riders tend to have more head/neck injuries than beginners, 17% vs. 13% (NS). Thus, with elevated skill level the injury pattern changed. For injury prevention, wrist guards and helmets are recommended for snowboard riders.
The effect of the 2005 British Columbia (BC) smoking cessation mass media campaign on a panel (N = 1,341) of 20-30-year-old smokers' attitudes is evaluated. The 5-week campaign consisted of posters, television, and radio ads about the health benefits of cessation. Small impacts on the panel's attitudes toward the adverse impacts of smoking were found, with greater impacts found for those who had no plans to quit smoking at the initial interview. As smokers with no plans to quit increasingly recognized the adverse impacts of smoking, they also increasingly agreed that they use smoking as a coping mechanism. Smokers with plans to quit at the initial interview already were well aware of smoking's adverse impacts. Respondents recalling the campaign poster, which presented a healthy alternative to smoking, decreased their perception of smoking as a coping mechanism and devalued their attachment to smoking. Evidence was found that media ad recall mediates unobserved predictors of attitudes toward smoking.
Awareness of hepatitis C virus (HCV) infection status is expected to influence risk behaviors. In 2004-2005, injection drug users (IDUs) recruited from syringe exchange programs (SEPs) and methadone clinics in Montreal, Canada, were interviewed on drug use behaviors (past 6 months) and HCV testing. Subjects (n = 230) were classified as low/intermediate risk (20.4% borrowed drug preparation equipment only) and high risk (19.6% borrowed syringes), and 54.5% reported being HCV positive. Logistic regression modeling showed that compared to no risk (60% borrowed nothing), low/intermediate risk was associated with fewer noninjecting social network members, poor physical health, and problems obtaining sterile injecting equipment. High risk was associated with all of these factors except social networks. HCV status was not associated with any level of risk. Improved access to sterile injecting equipment may be more important than knowledge of HCV status in reducing injection risks among this IDU population. The study limitations are noted and recommendations discussed.
We report findings from a multi-method study investigating drug injectors' access to needles and syringes in three large Russian cities (Moscow, Volgograd, Barnaul).
We undertook 209 qualitative interviews among drug injectors, and supplemented these with baseline data from a community-recruited survey of 1473 drug injectors.
Almost all (93%; 1277) injectors used pharmacies as their main source of clean injecting equipment, and only 7% (105) reported ever having had contact with city syringe exchange projects. Good access to syringes has coincided with the expansion of private pharmacies. Key factors contributing to pharmacy access included: geographic proximity; low cost; and the restrictive policies of exchange instituted at local syringe exchanges. A fear of police interference surrounded the use of pharmacies and syringe exchanges, and fed a reluctance to carry used needles and syringes, which in turn acted as a disincentive to syringe exchange attendance. The perceived benefits of syringe exchanges over pharmacies included the additional health services on offer and the social support provided, but these benefits were over-shadowed by disadvantages. Multivariable analyses of survey data in two cities show no differences on account of risk behaviour among injectors sourcing equipment from pharmacies compared to syringe exchanges.
HIV prevention coverage indicators need to include measures of pharmacy-based syringe distribution and not only measures of syringe exchange coverage. There is an urgent need to pilot pharmacy-based distribution and exchange projects in Russia as well as other forms of secondary syringe distribution. Alongside expanding the reach of dedicated syringe exchange projects, pharmacy-based syringe distribution, and exchange, may help improve coverage of cost effective HIV prevention measures targeting drug injectors.
The aim of this paper is to discuss the influence of arctic conditions on the occurrence of accidents especially from the point of view of the interaction between environment, activity and man. Special attention is paid to risk assessment, risk taking and risk compensation. According to the danger factor theory frostbites should be extremely common in arctic regions, but in reality serious frostbites appear rarely in accident statistics. This finding supports the interactive accident theories. Instead cold can be a contributing factor in accident and injury causation and the effect of cold is most often indirect. Frostbites can occur e.g. as a result of an accident, losing one's way because of darkness, snow storm etc., wet clothes, unexpected temperature changes, disease attack, alcohol-induced reasons such as immobility or excess risk taking etc. Temperatures below and above +20 degrees C increase unsafe behavior. In the Arctic it is impossible to remove all the potentially dangerous factors, because many typical features of working and living conditions are regulated by natural forces, the seasons etc. This makes accurate risk assessment and prediction especially important in accident prevention. If the person does not recognize the situations in which the risk factors exist, he/she cannot implement precautionary steps at the right moment and hence cannot avoid risks. Moreover, if better and safer machines, equipment and tools get people to take greater risks, the accident situation can even become worse.
Travel to foreign countries involves the risk of becoming a carrier of antibiotic-resistant bacteria, especially when the destination is a country with a high prevalence of this type of bacteria.
The aim of this study was to learn about the knowledge of antibiotic resistance, and the behaviour and risk-taking among travellers, who had become carriers of extended spectrum beta-lactamases (ESBL)-producing bacteria during travel to a high-prevalence country. A modified version of grounded theory was used to analyse 15 open interviews.
The analysis resulted in a core category: A need for knowledge to avoid risk-taking. Before the journey, the participants did not perceive there to be any risk of becoming a carrier of antibiotic- resistant bacteria. The low level of knowledge of antibiotic-resistant bacteria and transmission routes influenced their behaviour and risk-taking during their journey, resulting in them exposing themselves to risk situations. After their trip, the majority did not believe that their personal risk behaviour could have caused them to become carriers of ESBL.
The participants' lack of knowledge of antibiotic-resistant bacteria resulted in unconscious risk-taking during their journey, which may have resulted in becoming carriers of ESBL-producing bacteria.

Data was analyzed from the nationally representative Canadian Community Health Survey. A total of 17,549 adolescents reported whether they had "migraine headaches" (response rate 99.9%) and in what exercise activities they participated. Those with migraine reported more daily activity than migraine-free peers when corrected for age and sex. They were as likely to play contact sports but were more involved in other noncompetitive activities, such as walking (P
PURPOSE: There is very little data available on adaptation at adolescence after "visible adoptions" (children adopted from abroad), in terms of mental health, risk-taking and problem behaviour in comparison with nonadopted adolescents. This study describes such an outcome. MATERIAL AND METHOD: Data derived from self-reports from 125 adolescents aged 13-18 years who identified themselves as adopted, and who participated in two epidemiological surveys of 9329 adolescents. Their number was representative for children adopted from abroad. The other adolescents served as controls. RESULTS: Family life styles showed no differences between groups. Health was similar to that of the controls. Foreign adopted adolescents significantly often evaluated themselves as shorter and with early puberty. The proportion of adopted girls with suicidal thoughts was significantly larger, they also reported school truancy, not using safety belts, sexual intercourse, unpleasant sexual encounters, and contact with illicit drugs more often than the controls. The stress of early puberty could only partly explain this. CONCLUSIONS: Girls adopted from abroad, representing "visible adoptions", need additional attention and study during adolescence to expose causes for maladaption among some of them.
