[Perception of work conditions in a traditional farming community in Boa Esperança, Nova Friburgo, Rio de Janeiro State, Brazil].
The impact of pesticide use on human and environmental health has received attention from the international scientific community for some time, especially in developing countries where such chemical agents are used extensively and indiscriminately. The present study adopts a methodological approach to risk perception analysis based on rapid surveys, including: participatory observation; semi-structured interviews with key informants; and evaluation of local work processes. Field data analysis revealed several issues related to the risk perception profile of the study population, including the development of defensive strategies toward work hazards, subjective responses to potentially hazardous situations, and the role of individual risk perception as a determinant of human exposure to pesticides.

Correlates of hazard education programs for youth.
Virtually no research has examined the hypothesized benefits of hazard education programs for youth in helping to increase community resilience. This exploratory study examined the role of these programs in helping to increase child and family resilience to a range of future hazards. Various aspects of hazards programs were examined in relation to a wide range of child- and parent-reported hazard adjustments in a sample of 560 schoolchildren. Additional factors assessed included childrens' risk perceptions, knowledge of response-related protective activities, and hazard-related emotional factors. Overall, the results supported the role of hazards education programs in increasing hazard adjustments in the home. The findings also supported various aspects of education program involvement as being related to more realistic risk perceptions, increased knowledge, and increased interaction with caregivers. Analyses identified the following features of these programs as being particularly important: provision of specific knowledge (e.g., an emergency management perspective); multiple program involvement over time; and, importantly, promotion of increased interaction between children and parents. Overall, findings supported the idea that hazards education programs for youth provide one gateway through which communities can increase their resilience to the effects of a major hazardous event. Findings also provided an initial foundation for further research in this emerging area.

Brief report: how do adolescents perceive the risks related to cell-phone use?
Besides the social risks of incivility and impoliteness (I-incivility), cell-phone use is classically associated with two types of physical risk: microwave radiation (LIMRadiation) and decreased attention while driving (CPUWDriving). As the literature has showed that adolescents' risky behavior was consistent with their risk perception, we ran a self-report survey to evaluate 1/how French adolescents (n=1129) perceived physical risks related to CPUWDriving, exposure to LIMRadiation, and social risks related to I-incivility; and 2/the factors underlying these risk perceptions. Results showed that adolescents have an acute perception of the risks associated with CPUWDriving and appeared to be concerned, as a whole, with social risks related to I-Incivility. They do not appear particularly concerned by the risks related to LIMRadiation, which may reflect societal confusion about risks still considered as hypothetical and/or based on equivocal evidence. Gender, ethnicity, and age were not predictive for perceived risks. Level of schooling had a positive influence on perceived risks related to CPUWDriving and I-Incivility, and cell-phone ownership had an inverse relationship with perceived risks related to I-Incivility.

Is there evidence for behaviour change in response to AIDS in rural Zimbabwe?
This article reports on evidence for behaviour change in response to AIDS among women in two rural areas of Manicaland Province, Zimbabwe. It examines self-reported data on two overlapping areas of behaviour: (1) actions taken to avoid HIV-1 infection; and (2) fertility practices. The latter were used to assess the validity of the former, given that self-reported behaviour data are notoriously problematic. It is concluded that while self-reported behaviour change is exaggerated, the true level of change has nonetheless been significant and includes delayed onset of sexual relations, increased use of condoms and, possibly, increased monogamy. Reported actions taken to avoid HIV-1 infection and differentials in fertility practices were correlated with data on demographic, social and psychological factors. Differentials in fertility practices were associated with heightened risk perception--particularly when based on personal acquaintance with AIDS patients--but not with greater knowledge of HIV-1/AIDS. Results from the study suggest that effective behaviour change in Manicaland is facilitated by greater knowledge, experience and personal risk perception but obstructed by low female autonomy, marital status and economic status, and by male labour migration and alcohol consumption. Gaps in knowledge included misconceptions about the distinction between HIV-1 and AIDS, the influence of STDs, perinatal transmission, and incorrect modes of transmission. Better knowledge was associated with education, religion, travel and media exposure Personal risk perception was quite high (42%) and correlated with non-marriage, media exposure and contact with medical services. Few respondents knew close relatives with HIV/AIDS (4%) but nearly a quarter of those who felt in danger of infection said this was because friends and relatives were dying of AIDS. Many reported credible behavioural responses, some of which would only be effective given their partner's co-operation. Intensified behaviour interventions are needed which should include peer-education initiatives targeting men and individuals without access to modern media. The epidemic may accelerate fertility decline in rural Zimbabwe through behavioural as well as biological change.

Health perceptions and risk behaviors of lung cancer survivors.
BACKGROUND: Lung cancer survivors are at an increased risk for recurrence and the development of secondary tumors and other comorbid conditions. However, little is known about lung cancer survivors' risk behaviors and the effect of these behaviors on overall health perceptions. OBJECTIVE: The purpose of this study was to describe the prevalence of health risk behaviors among non-small cell lung cancer survivors and their relationship perception to overall health. METHODS: One hundred forty-two survivors of non-small cell lung cancer with a minimum of 5 years disease free completed a battery of questionnaires to assess perception of health status and self-reported risk behaviors (smoking, exposure to secondhand smoke, alcohol use) and weight before and after diagnosis. Urinary cotinine level was used to verify smoking status, and actual height and weight were obtained to determine overweight status (body mass index, >/=25). Descriptive statistics and logistic regression were used to analyze the data. RESULTS: Seventy percent of participants reported their health as good to excellent. Although 81% quit smoking after diagnosis, 13.4% continued to smoke and 28% reported exposure to secondhand smoke. Approximately half the sample (58%) drank alcohol (16.3% quit after diagnosis) and was overweight (51%). A strong agreement between current smoking and exposure to secondhand smoke was observed. In a multivariate analysis, smoking (odds ratio [OR], 7.02; CI, 2.45 to 20.13), exposure to secondhand smoke (OR, 5.37; CI, 2.42 to 11.95), alcohol use (OR, 9.04; CI, 3.28 to 24.92), and overweight (OR, 8.51; CI, 3.44 to 21.10) were independent predictors of perceived poor health status. CONCLUSION: Although most lung cancer survivors have made healthy lifestyle changes, a substantial proportion has not. Our findings suggest the need for multiple risk factor interventions to decrease risk behaviors and improve overall health after a cancer diagnosis.

Why it won't happen to me: perceptions of risk factors and susceptibility.
Four studies were conducted with college student subjects to examine: (1) perceptions of susceptibility to health and safety risks; (2) factors that subjects see as important in determining their susceptibility; and (3) subjects' actual standing on objective risk factors. Subjects were generally unbiased about hereditary risk factors and were even somewhat pessimistic about environmental risk factors. Their views of their own actions and psychological attributes, however, were excessively optimistic. Few acknowledged actions or psychological attributes that increased their risk. This pattern of findings helps to explain why risks thought to be controllable (i.e., preventable by personal action) are likely to evoke unrealistic optimism about susceptibility. Family histories of health problems were incorporated into judgments of susceptibility, but, except for smoking, correlations between behavioral risk factors and judgments of susceptibility were surprisingly weak. Self-esteem enhancement is suggested as a motive that could explain many of the present findings. Several recommendations are offered for health campaigns that seek to produce more realistic perceptions of susceptibility to health and safety problems.

Limits of knowledge and the limited importance of trust.
Perceived risk and related attitudes have been implicated as major factors in many of the difficult policy problems that face modern society (nuclear power, genetically modified food, etc). Experts often argue that no or very small risks are involved; people are still worried. Why? The standard answer is lack of trust. Data on trust and risk perception, however, point to only a weak relationship between the two (r approximately 0.3). It is suggested here that the reason for the surprisingly minor importance of trust is that people believe that there are clear limits to how much science and experts know. Results are presented from studies of risk perception of the public, experts, and politicians. Politicians and members of the public believe that there are many unknown effects of technology and such beliefs were strongly related to their perceived risk. Experts on nuclear waste, on the other hand, seemed to believe that little is unknown in their field of expertise. Regression analyses of risk perception showed the unknown-effects factor to be a more important explanatory factor than trust for the public and politicians.

HIV status of sexual partners is more important than antiretroviral treatment related perceptions for risk taking by HIV positive MSM in Montreal, Canada.
OBJECTIVE: To examine the role of antiretroviral treatment related perceptions relative to other clinical and psychosocial factors associated with sexual risk taking in HIV positive men who have sex with men (MSM). METHODS: Participants were recruited from ambulatory HIV clinics in Montreal. Information on sociodemographic factors, health status, antiretroviral treatment related perceptions, and sexual behaviours was collected using a self administered questionnaire. At-risk sexual behaviour was defined as at least one occurrence of unprotected insertive or receptive anal intercourse in the past 6 months. Multivariate logistic regression was performed to evaluate the associations between at-risk sexual behaviour and covariates. RESULTS: 346 subjects participated in the study. Overall, 34% of subjects were considered at risk; 43% of sexually active subjects (n=274). At-risk sexual behaviour was associated with two antiretroviral treatment related perceptions: (1) taking antiretroviral treatment reduces the risk of transmitting HIV (adjusted odds ratio (OR), 2.10; 95% confidence interval (CI), 1.16 to 3.80); and (2) there is less safer sex practised by MSM because of HIV treatment advances (OR, 1.82; CI, 1.14 to 2.90). Other factors, however, were more strongly associated with risk. These were: (1) safer sex fatigue (OR, 3.23; CI, 1.81 to 5.78); (2) use of "poppers" during sexual intercourse (OR, 6.28; CI, 2.43 to 16.21); and (3) reporting a greater proportion of HIV positive anal sex partners, compared with reporting no HIV positive anal sex partners: (a) <50% HIV positive (OR, 16.79; CI, 4.70 to 59.98); (b) > or =50% HIV positive (OR, 67.67; CI, 15.43 to 296.90). CONCLUSION: Despite much emphasis on HIV treatment related beliefs as an explanation for sexual risk taking in MSM, this concern may play a relatively minor part in the negotiation of risk by HIV positive MSM. Serosorting, safer sex fatigue, and the use of poppers appear to be more important considerations in understanding the sexual risk behaviours of HIV positive MSM.

Reactions to genetically modified food crops and how perception of risks and benefits influences consumers' information gathering.
Previous research has reported strong consumer perception that genetically modified (GM) food crops may lead to adverse outcomes in a number of different areas. This is despite the widespread promulgation of the potential benefits and opportunities ascribed to the same technology by many scientists and other experts. A computer-based information gathering and evaluation task was completed by 198 adults to assess the extent to which their initial focus on the dangers or opportunities of genetic modification, or both, could be ascribed to the manner in which they gathered information on the topic (heuristically vs. systematically). Results did not confirm the hypothesis that initial focus (risks, benefits, or both) predicted ongoing information gathering and evaluation behavior. Moreover, also contrary to prediction, most participants primarily used systematic strategies when deriving their initial position, regardless of that opinion. Participants found it difficult to achieve a balanced perspective on GM food crop, even though balanced argument, as measured by order of story selection and time spent reading, was preferred as the source of information. Perceived importance is probably the most influential variable determining information gathering about issues or events to which a level of risk is attached.

[Psychosocial aspects of HIV infection among women in Brazil].
OBJECTIVE: To analyze the risk perception among HIV-positive women before getting a positive test result. METHODS: An exploratory study using in-depth interviews was conducted among 26 women who attended the outpatient clinic of a regional health center in Maringá, Brazil. The sample was drawn according to the women's availability. The interviews were carried out using a semi-structured questionnaire with open and closed questions on social-demographics, knowledge of primary and secondary prevention, risk perception before getting the test results, and impact of the diagnosis on their lives and sexual activity. Data was assessed using content analysis. RESULTS: Though the participants were aware that anyone could get infected, none of them believed they could actually be infected. Psychological mechanisms such as denial, avoidance, thought omnipotence, and projection are encouraged by practices and gender-dominant relationships in the Brazilian culture, which increases women's vulnerability to HIV infection. They feel helpless and many have unprotected sex with their partners, and are prone to unwanted pregnancies and re-infection. CONCLUSION: HIV prevention programs should take into account psychological, social, economical and cultural aspects that impact on women's vulnerability before and after being infected. For a wider outreach of actions, programs cannot to be restricted to massive information diffusion and need to apply psychoeducational strategies to small groups of women not only to increase their medical knowledge but also to enhance their awareness.

Perceptions of risks of smoking among Asian Americans.
BACKGROUND: Tobacco use is the single most preventable cause of illness and death in the United States. Few studies focus on Asian Americans, one of the fastest growing but underserved populations in the United States. METHODS: A cross-sectional survey method was used for this study. The study sample was identified by using a stratified-cluster proportional sampling technique. A questionnaire was developed in English, translated into the four Asian languages (Chinese, Koreans, Vietnamese, and Cambodians), and back-translated. The sample consisted of 1174 individuals, distributed as follows: Chinese, 34.9%; Korean, 37.1%, Vietnamese, 16.7%; Cambodian, 8.4%; and others, 2.7%. RESULTS: Findings indicated that attitudes toward tobacco-related dangers were associated with smoking status: former and never smokers held more negative perceptions regarding smoking compared to current smokers. Further, results indicated that the Asian American subgroups differed in their respective attitudes. The study is the first to compare attitudes toward tobacco-related dangers among racial/ethnic and language subgroups of Asian Americans. CONCLUSION: The growing body of empirical data on smoking among Asian Americans indicates that smoking cessation programs should take into account variations in smoking-related perceptions and attitudes across the ethnic subgroups.

Skin cancer awareness in suburban employees: a Hispanic perspective.
Skin cancer is the most common form of cancer in the United States and accounts for an estimated 1 million new cases per year. In the white population, the rate of new melanomas diagnosed yearly has more than doubled from 5/100,000 in 1973 to 12/100,000 in 1990. The current lifetime risks for white persons are estimated to be 28% to 33% for basal cell carcinoma and 7% to 11% for squamous cell carcinoma. Skin cancer is more common in sun-sensitive, fair-skinned individuals but can occur in any ethnic group, especially with exposure in tropical or sunny climates. Little is known about awareness of skin cancer, risk perception, and performance of skin self-examination (SSE) by people with skin that rarely burns. Our purpose was to evaluate skin cancer awareness, perceptions of skin cancer risk, and performance of SSE in a Hispanic versus non-Hispanic white population with similar access to health care and promotion. One hundred forty people employed by a suburban city voluntarily attended a free skin cancer screening and completed a self-administered survey. Hispanic individuals reported decreased skin sensitivity and tendency to burn. Non-Hispanic individuals believed they were at greater than average risk for skin cancer, and most Hispanics believed they were at average or below average risk. None of the 27 Hispanics reported ever being taught SSE. More non-Hispanics (32%) had performed SSE within the last year than Hispanics (15%). Regular SSE was associated with a history of skin cancer. Multimedia messages usually link skin cancer warning signs and early detection strategies with having sun-sensitive skin. People without sun sensitivity did not perceive themselves as being at risk, did not learn the warning signs of skin cancer, and did not perform SSE. Awareness of melanoma and non-melanoma skin cancer and perception of risk among Hispanics were less than among non-Hispanics, which may contribute to presentation for care at an advanced stage.

Societal responses to familiar versus unfamiliar risk: comparisons of influenza and SARS in Korea.
This study examines the connections between familiar (influenza) and unfamiliar (SARS) risks among the general public in a SARS affected society. Using a survey of 350 respondents in Chonju, we find that risk perceptions and a belief that influenza vaccination reduces the incidence of SARS explain behavioral intentions for influenza vaccination and purchase responses to a hypothetical SARS vaccine. Those respondents who believe that an influenza vaccination will very likely reduce SARS incidence have a high probability (79%) of intending to vaccinate, but a much lower WTP for a SARS vaccine than those without such a belief. This belief undoubtedly was influenced by a reframing of influenza vaccination as preventing SARS. Such reframing may lead to short-term improvements in vaccination rates to the detriment of long-term SARS vaccination development. When compared with a similar study in Taiwan, societal risk perceptions of SARS and WTP for a vaccine vary greatly according to the extent of a society's experience with SARS.

Perceptions of risks of eating undercooked meat and willingness to change cooking practices.
Knowledge and awareness of food safety issues relating to improperly cooked hamburger and willingness to change hamburger cooking practices were examined from a representative sample of 1004 adult Texans. Awareness of the danger of improperly cooked hamburger, knowledge of specific foodborne pathogens and knowledge of food safety practices had no effect on willingness to change behavior, but respondents who were better-educated, female and Hispanic and respondents who used newspapers/magazines or televisions were all more likely to report willingness to change their cooking practices.

Perceptions of smoking risk as a function of smoking status.
Perceptions of the health risks associated with smoking in comparison with not smoking were assessed for the self and the "typical smoker" among four groups of adults: current, former and nonsmokers in the community, and smokers who had joined cessation clinics to help them quit. Comparisons across groups indicated that risk perceptions differed as a function of smoking status. Clinic attendees reported the highest smoking risk and the greatest perceived benefit of not smoking, and community smokers reported the lowest of each. In addition, community smokers were the only group to exhibit an "optimistic bias" (i.e., a perception that they were less vulnerable to health risk than was the typical smoker). Results from this cross-sectional study suggest that the decision to engage in and to stop risky behaviors is related to the perceptions of the health risk associated with those behaviors.

Perceptions of risk and behaviour change for prevention of HIV among married women in Mumbai, India.
Heterosexual transmission accounts for the majority of cases in India, an epicentre of the HIV/AIDS pandemic, with increasing rates of infection in married women contracting HIV from an infected spouse. Cultural roles and position of married women in Indian society render targeted risk-reduction programmes difficult. To investigate HIV/AIDS-related knowledge, perceptions, and behaviour change among married women in India, an interview-based survey was conducted with 350 married women in Mumbai, of whom 67% (236) were aware of HIV/AIDS. Although 59.3% (140) of those aware mentioned indiscriminate sexual activity as increasing risk of HIV, only two (41%) in five women perceived HIV as a threat to the community; one (12%) in eight perceived personal risk of getting infected as high; and only 7.2% (17) reported behaviour change to avoid infection. When probed for reasons for not changing behaviour, most women cited their personal behaviour of monogamy, not being in an at-risk group, such as commercial sex workers, and trust in their husbands. Education programmes among married women that enable better understanding of risks are urgently required. Since marriage and motherhood are important in the Indian cultural context, male spouses should be included in risk-reduction programmes.
