BACKGROUND: Travel to hepatitis A-endemic countries is frequent among North Americans. Such travel carries significant risks for the individuals themselves and for the general population. We documented the patterns of use of travel clinics in a large Canadian adult population. METHODS: Travelers who had visited a hepatitis A-endemic country between 1990 and the time of the survey in 1999 were eligible. Subjects were identified from a representative sample of 4,002 adults from the two largest Canadian provinces. They were contacted by random digit dialing and interviewed by telephone. RESULTS: Only 15% of trips had been preceded by a visit to a travel clinic. The probability of visiting a travel clinic was approximately 10 times greater for travelers considered to be in the high-risk category than for those in the low-risk category, but the former represented only 2% of the total. The probability of visiting a travel clinic was approximately 23 times greater for travelers who were aware of the health risks in their country of destination. Income level was not associated with attendance at a travel clinic, and cost was rarely mentioned as a reason for not attending such a travel clinic before departure. CONCLUSIONS: Each year, millions of Canadian travelers go to hepatitis A-endemic countries without consulting a travel clinic. Active steps must be taken by public health authorities to improve their utilization of health services and prevent the accrued health risk for these travelers. 相似文献

BACKGROUND: In South America, little is known about sexual behavior and risk factors for acquiring sexually transmitted diseases (STDs) among travelers and among local people sexually interacting with travelers. There is evidence that, in Peru, significant sexual interaction between these groups exists. METHOD: An anonymous written questionnaire was administered to travelers in the airport and bus stations before they left Cuzco. RESULTS: Of the travelers,5.6% engaged in sexual activity with a new partner during their stay in Cuzco. Sexual intercourse with other travelers was most common (76/140, 54.3%), followed by sex with local partners (57/140, 40.7%), and with commercial sex workers (3/140, 2.15%). Consistent condom use was reported by 97/140 (69.3%). In the multivariate analysis, the following variables were independently associated with casual sex: male gender, single marital status, age between 15 and 35 years, non-United States travelers (NUSTs), traveling alone or with friends, length of stay more than 30 days, homosexual or bisexual orientation, and expectation of having sex before traveling. Homosexual and bisexual travelers had 3 or more new sexual partners more frequently than heterosexual travelers (4/8, 18/129, OR=6.17 (1.16相似文献

Hepatitis E is endemic in (sub)tropical countries while only sporadic cases have been described in industrialized countries. In a prospective study among 1270 short-term Dutch travelers to (sub)tropical countries we found no seroconversion to anti-hepatitis E virus (HEV) antibodies, indicating a very low risk for travelers to acquire a hepatitis E infection. 相似文献

BackgroundThe intersection of drug use, sexual pleasure and sexual risk behaviour is rarely explored when it comes to poor women who use drugs. This paper explores the relationship between sexual behaviour and methamphetamine use in a community-based sample of women, exploring not only risk, but also desire, pleasure and the challenges of overcoming trauma.MethodsQuantitative data were collected using standard epidemiological methods (N = 322) for community-based studies. In addition, using purposive sampling, qualitative data were collected among a subset of participants (n = 34). Data were integrated for mixed methods analysis.ResultsWhile many participants reported sexual risk behaviour (unprotected vaginal or anal intercourse) in the quantitative survey, sexual risk was not the central narrative pertaining to sexual behaviour and methamphetamine use in qualitative findings. Rather, desire, pleasure and disinhibition arose as central themes. Women described feelings of power and agency related to sexual behaviour while high on methamphetamine. Findings were mixed on whether methamphetamine use increased sexual risk behaviour.ConclusionThe use of mixed methods afforded important insights into the sexual behaviour and priorities of methamphetamine-using women. Efforts to reduce sexual risk should recognize and valorize the positive aspects of methamphetamine use for some women, building on positive feelings of power and agency as an approach to harm minimization. 相似文献

Sexual risk behaviors and substance use among alcohol abusing HIV-positive men who have sex with men
Parsons JT Kutnick AH Halkitis PN Punzalan JC Carbonari JP 《Journal of psychoactive drugs》2005,37(1):27-36
An ethnically diverse sample (79.0% men of color) of HIV seropositive (HIV+) men who have sex with men (MSM) with alcohol use disorders from the New York City metropolitan area was recruited from a variety of settings frequented by such men. Data were collected using quantitative assessments and calendar based techniques at the baseline assessment of a longitudinal study assessing the relationship between alcohol and substance use and sexual risk behaviors as well as alcohol use and HIV disease progression. Data were selected on a sample of 253 HIV+ MSM (mean age = 38.55, SD = 6.73). Of these, the majority of participants (80.2%, n=203) reported engaging in sexual behaviors with casual partners. In terms of sexual behaviors that put partners at greatest risk for HIV transmission, unprotected anal insertive intercourse was most likely to occur with unknown status casual partners (46.8%, n=95) than with either HIV negative casual partners (19.2%, n=39) or with HIV+ casual partners (40.8%, n=83). Further, bivariate analyses indicated significant relationships between the use of several substances and sexual behaviors that put partners at greatest risk for HIV transmission, as well as a significant positive relationship between drinks per drinking day and viral load. 相似文献

The effect of failed appointments at a teratogen information service (TIS) clinic on pregnancy outcome is not known. The objectives of our study were 1) to identify predictors of failed appointments and 2) to evaluate if failed appointments were associated with a higher rate of adverse pregnancy outcome among women booked for counseling at a TIS clinic over 5 consecutive months. Of 242 patients scheduled to come to clinic, 154 were followed-up at 20 weeks gestational age. Women who were pregnant at 20 weeks were more likely to have attended the clinic (81% attendance rate), than women who had a spontaneous abortion, a therapeutic abortion, or an ectopic pregnancy (54% attendance rate) (P = 0.003). Independent predictors of failed appointments included exposure to illicit drugs, history of previous spontaneous abortion, and a main concern that was a nonmedication exposure. In conclusion, pregnant women who failed appointments at a TIS clinic are at greater risk for not being pregnant at 20 weeks gestational age than those who attended the clinic. Telephone counseling should be considered in selected cases to ensure that all women get relevant information at the time of appointment booking. 相似文献

BACKGROUND: Malaria transmission in Nepal is focal and seasonal. Based on data in returning travelers the risk of malaria is low. Sources of advice give contradictory information regarding the need for chemoprophylaxis. As a result, a degree of confusion exists among visitors. The aim of this study was to describe chemoprophylactic practices among travelers to Nepal and to document differences in advice according to its source and the country in which it was given. METHODS: A questionnaire survey of tourists attending the CIWEC Clinic Travel Medicine Center, Kathmandu between June 2000 and May 2001. Resident expatriates and indigenous Nepalese were excluded. RESULTS: Completed questionnaires were obtained from 1,303 respondents. Two hundred and eighty-eight respondents were taking chemoprophylaxis specifically for their trip to Nepal (22%), whereas 958 were not. Travelers from the United Kingdom and Denmark were significantly more likely, and those from the United States and Germany significantly less likely, to be taking chemoprophylaxis. Most travelers sought pretravel advice (71%), and all sources were more likely to advise them not to take chemoprophylaxis than to take it. However, travelers advised by a family practitioner were significantly more likely to be taking chemoprophylaxis than those advised by a travel medicine specialist. Of those taking chemoprophylaxis, 53% were doing so for a visit to the Terai alone, 33% for all areas of Nepal, and 6% for the Kathmandu Valley. Nine different chemoprophylactic regimes were in use. Six hundred and forty respondents who were not taking chemoprophylaxis had been advised that it was not necessary; 276 had made the choice themselves; and 131 had been taking chemoprophylaxis but had stopped while in Nepal. Twenty-eight of these respondents had stopped because of side effects. The most common reason for choosing not to take chemoprophylaxis was either the occurrence of side effects or the fear of them (31%). CONCLUSIONS: The variable and ultimately low risk of contracting malaria in Nepal has resulted in a lack of consensus and a wide range of opinion regarding the need for chemoprophylaxis. There is a need for clarification and tighter definition of the malaria risk faced by travelers to Nepal to avoid unnecessary chemoprophylaxis use while protecting those at significant risk. 相似文献

We examined substance use in relationship to transmission risk behavior (unprotected insertive, UIAI, or receptive anal intercourse, URAI) between HIV-positive men who have sex with men (MSM) and their HIV-negative or unknown serostatus partners. Men who engaged in transmission risk behavior with casual partners were more likely than men who did not engage in such behavior to have used various substances. Users of certain drugs were specifically less likely to use condoms with HIV-negative or unknown status partners than users. Of men who drank alcohol, those who drank more frequently before or during sex engaged in significantly more UIAI with casual partners. Of men who used drugs, those who used more frequently before or during sex were more likely to engage in URAI with casual partners. In multivariate analyses, use of inhalants as well as drinking before or during sex predicted UIAI, while use of inhalants as well as noninjection drug use before or during sex predicted URAI. HIV prevention programs for HIV-positive MSM should focus on decreasing substance use and use specifically before or during sex. Developing prevention programs for substance-using MSM is critical to improve community health and decrease HIV transmissions. 相似文献

Sexual risk behavior among persons dually diagnosed with severe mental illness and substance use disorder 总被引:2,自引:0,他引:2
Meade CS 《Journal of substance abuse treatment》2006,30(2):147-157
Persons dually diagnosed with severe mental illness (SMI) and substance use disorder (SUD) have disproportionately high rates of HIV and other sexually transmitted infections (STIs). This study examined the relationship between multiple sexual risk behaviors among persons with active, remitted, and no SUD. Participants were 152 adults with SMI recruited from multiple treatment sites. A structured interview assessed the participants' psychiatric, psychosocial, and behavioral factors. Rates of sexual risk behavior in the past 3 months were high and differed across the SUD groups. Multivariate logistic regression models found that lifetime SUD predicted sexual activity and partner-related risk whereas active substance abuse predicted condom-related risk. The results also support indirect effects of interpersonal and psychiatric factors (e.g., romantic partnership and psychotic disorder). Findings underscore the need for integrated HIV/STI prevention interventions targeting dually diagnosed patients. 相似文献

BACKGROUND: This study aimed to determine the knowledge, attitudes and practices of Swiss business travelers with regard to malaria. METHODS: Questionnaires printed in three languages were distributed by employers, travel agencies and tropical medicine specialists to business travelers with destinations in malaria endemic countries. RESULTS: In total, 401 questionnaires were evaluated. Thirty-three percent visited high-risk areas, 27% visited low-risk areas, and 40% visited only malaria-free areas within endemic countries. Among the investigated business travelers, 6% had experienced malaria infection, and 29% had previously had blood smears tested for malaria at least once. Almost all business travelers, 95%, knew that mosquitoes are the main vectors of malaria. The infection risk between dusk and dawn was known to 71%, and the incubation time to 36%. Apart from fever (99%) and headache (63%), other malaria symptoms were known to only 13% to 36% of the travelers. If signs of illness such as fever and headache occurred, 63% would react adequately and seek medical advice within 24 h. Only 16% of the travelers to African high-risk areas followed the recommended behavior concerning anti-mosquito and antimalarial strategies; 31% of those on trips to low-risk areas used an adequate protective strategy. Of the business travelers using chemoprophylaxis during travel, just 50% continued intake post travel, as requested, after leaving the endemic area. CONCLUSIONS: Business travelers are well informed regarding the mode of transmission and the risk of malaria at specific destinations but tend to comply poorly with anti-mosquito and chemoprophylactic strategies. The knowledge, attitudes and practices of business travelers with regard to malaria prevention need to be improved. 相似文献

IntroductionInjection drug use (IDU) remains a significant public health problem. IDU has been associated closely with the opioid crisis; driving overdose, HIV, and Hepatitis C (HCV) infection nationwide. Syringe services programs (SSPs) remain pivotal evidence-based interventions to reduce harm and engage subgroups of people who inject drugs (PWID). This study aims to provide policy considerations from the IDEA SSP, the first legal SSP in the state of Florida.MethodsWe performed a latent class analysis on patterns of substance use among participants (N = 982) newly enrolled in a syringe services program (SSP). Associations between classes of substance use and sociodemographic variables, risky injection and sex behaviors, HIV/HCV status and syringe coverage were analyzed using the R3STEP and BCH 3-step procedures in latent class regression.ResultsWe found a three-class solution: Heroin-Dominant class (73.9%), Methamphetamine-Dominant class (9.5%) and Heroin/Cocaine class (16.6%). Compared to Heroin-Dominant class, the Heroin/Cocaine class were more likely to report homelessness, sharing works, unprotected sex, public injection, and to be HCV positive. Compared to both Heroin-Dominant and Heroin/Cocaine classes, the Methamphetamine-Dominant class were more likely to be male, Hispanic, gay or bisexual orientation, HIV positive, to report unprotected sex and sex with PWID. In addition, the lowest and highest syringe coverage were among those in the Heroin/Cocaine and Methamphetamine-Dominant classes, respectively.ConclusionExisting interventions among this population to mitigate infectious disease risk, such as SSPs, can be a used to engage differing PWID populations. However, multi-component, targeted preventive interventions and need-based syringe distribution policies are required to further reduce HIV and HCV risk among various PWID populations. 相似文献

This study examined impulsivity as a moderator of the relationship between meth use and sexual risk behavior in a sample of HIV-positive meth-using Men who have Sex with Men (MSM). Higher impulsivity was associated with less education, lower income, being unemployed, psychiatric diagnosis, and higher Beck depression scores. Intensity of meth use and sexual risk behavior were significantly correlated. In a multiple regression analysis, more education, greater intensity of meth use and higher levels of impulsivity predicted more unprotected sex. To test for moderating effects of impulsivity, an interaction term was added to the regression. The interactive effects model was statistically significant. A plot of the interaction revealed that the relationship between intensity of meth use and total unprotected sex was strongest among participants who had higher levels of impulsivity. This suggests that targeting impulsivity in interventions may help reduce sexual risk behaviors in high intensity meth-using HIV-positive MSM. 相似文献

Antisocial behavior often involves frequent risk-taking, e.g. excessive substance use and criminality, which may lead to destructive consequences. In the present study, adults with a history of high-risk behavior (primarily drug dependence and conduct disorder) and matched controls worked on a novel laboratory task designed to measure risk-taking. The contingencies of the task were such that choosing a 'risky' response option resulted in a net loss of monetary earnings compared to a safer, more conservative response alternative. The risky option offered a low probability of a large monetary reward or a high probability of a smaller monetary loss. The non-risky option protected current earnings. High-risk history subjects chose the risky option more often, had lower overall earnings, and were more likely to persist in making (losing) risky responses following a single gain on the risky option. The data support theories of maladaptive behavior focused on hypersensitivity to reward and insensitivity to aversive events. 相似文献

BackgroundThe use of multiple illicit drugs (polydrug use) is associated with health-related harms and elevated risk of drug overdose. Polydrug use in common among women who use ‘hard’ drugs, such as cocaine, heroin or methamphetamine.MethodsQuantitative data collection was conducted with a community-recruited sample of 624 women who used heroin, methamphetamine or cocaine in Oakland, CA during 2014–2015. We conducted latent class analysis to classify polydrug use patterns. We assessed associations between classes of polydrug use and infectious disease risk behaviors, health care utilization and unmet health care need.ResultsWe identified four distinct classes of drug use: (1) predominantly crack (52% of women); (2) powder cocaine & non-heroin opioids (8%); (3) moderate polydrug use (25%); (4) heavy polydrug use (15%). Odds of sexual risk, injection drug use and unmet healthcare need were twice as high in the heavy polydrug use class as the predominantly crack class (p > 0.01 for each outcome). The rate of binge drinking (as days per month) was also significantly higher in the heavy polydrug class (p = 0.01). The moderate polydrug use class had higher odds of injection drug use and drug treatment participation, compared to the mainly crack class (p < 0.001 for each outcome). There were no differences between classes in health insurance or health care utilization.DiscussionReduction of polydrug use could be an effective harm reduction strategy to address sexual and injection risk among women. The use of both opioids and stimulants in three of the four classes suggests that multi-modal substance abuse treatment approaches may be most appropriate. 相似文献
