Relationship Characteristics and Risk of HIV Infection: Rusbult's Investment Model and Sexual Risk Behavior of Gay Men in Steady Relationships,

JOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 1 2006
Udi Davidovich
This study examined the effects of relationship characteristics, as measured by Rusbult's (1980) investment model, on safer-sex behavior between steady gay male partners. Analyses showed that low satisfaction with the relationship was associated with more risky unprotected anal intercourse (UAI). High commitment to the relationship was associated with more practice of negotiated safety (i.e., having safe UAI after both partners have tested negative for HIV and have reached sexual safety agreements). High relationship investment was associated with more risky UAI (borderline significant). We conclude that using relationship satisfaction, commitment, and investment as co-determinants of sexual risk behavior could prove useful in the development of new HIV-prevention strategies for gay men in relationships.

Race/Ethnic Differences in Effects of Family Instability on Adolescents' Risk Behavior

JOURNAL OF MARRIAGE AND FAMILY, Issue 2 2010
Paula Fomby
We used data from the National Longitudinal Study of Adolescent Health (N = 7,686) to determine whether racial and ethnic differences in socioeconomic stress and social protection explained group differences in the association between family structure instability and three risk behaviors for White, Black, and Mexican American adolescents: delinquent behavior, age at first nonmarital sex, and age at first nonmarital birth. The positive association between mothers' union transitions and each outcome for White adolescents was attenuated by social protection. The association of instability with age at first sex and first nonmarital birth was weaker for Black adolescents but not for Mexican American adolescents. The weaker association was explained by Black adolescents' more frequent exposure to socioeconomic stress in the context of union instability. [source]

Sexual Risk Behavior of Travelers who Consulted a Pretravel Clinic

JOURNAL OF TRAVEL MEDICINE, Issue 1 2008
Mieke Croughs MD
Objective The objective of this study was to determine to which degree travelers who received pretravel advice at a travel clinic have protected or unprotected sexual contact with a new partner and what factors influence this behavior. Method An anonymous questionnaire was sent to travelers who came to a pretravel clinic between June 1 and August 31, 2005. Risk factors for casual travel sex and predictors of protected sex were studied in a multivariate model. Results A total of 1,907 travelers were included (response rate 55%) in the study. Only 4.7% of the respondents had sexual contact with a new partner, and 63.1% of these new partners were from the country of destination. Of those who had casual travel sex, 52.4% did not expect this (women 75%), 30.9% did not always use condoms, and 41% were not protected against hepatitis B. Independent risk factors for casual travel sex were traveling without steady partner (OR 14.4), expecting casual travel sex (OR 9.2), having casual sexual contacts in the home country (OR 2.4), non-tourist journeys (OR 2.2), being male (OR 2.1), the fact that the information on sexually transmitted infections (STI) had been read (OR 2.0), and traveling to South and Central America (OR 2.0). Taking condoms along (OR 5.4) and reading the information on STI (OR 3.3) were identified as independent predictors of protected sex. Conclusions Travelers have substantial sexual risk behavior. Casual sex is usually not expected, and the most important predictor is traveling without a steady partner. We would advice every client of a travel clinic who will travel without a steady partner to read the STI information, to take condoms along, and to be vaccinated against hepatitis B. [source]

Implications of Racial and Gender Differences In Patterns of Adolescent Risk Behavior for HIV And Other Sexually Transmitted Diseases

PERSPECTIVES ON SEXUAL AND REPRODUCTIVE HEALTH, Issue 6 2004
Carolyn Tucker Halpern
CONTEXT: Sexual and substance use behaviors covary in adolescence. Prevalence of HIV and other sexually transmitted diseases (STDs) differs according to race and gender, yet few studies have systematically investigated risk behavior patterns by subgroup, particularly with nationally representative data. METHODS: A priori considerations and K-means cluster analysis were used to group 13,998 non-Hispanic black and white participants in the National Longitudinal Study of Adolescent Health, Wave 1, according to self-reported substance use and sexual behavior. Multinomial logit analyses examined racial and gender differences by cluster. RESULTS: Among 16 clusters, the two defined by the lowest risk behaviors (sexual abstinence and little or no substance use) comprised 47% of adolescents; fewer than 1% in these groups reported ever having received an STD diagnosis. The next largest cluster,characterized by sexual activity (on average, with one lifetime partner) and infrequent substance use,contained 15% of participants but nearly one-third of adolescent with STDs. Blacks were more likely than whites to be in this group. Black males also were more likely than white males to be in three small clusters characterized by high-risk sexual behaviors (i.e., having had sex with a male or with at least 14 partners, or for drugs or money). Black females generally were the least likely to be in high-risk behavior clusters but the most likely to report STDs. CONCLUSIONS: Adolescents' risk behavior patterns vary by race and gender, and do not necessarily correlate with their STD prevalence. Further investigation of adolescents' partners and sexual networks is needed. [source]

Health Risk Behavior of Rural Low-Income Expectant Fathers

PUBLIC HEALTH NURSING, Issue 4 2006
Kevin D. Everett
ABSTRACT Objectives: To assess expectant fathers' health risk behaviors and attitudes about pregnancy-related health issues. Pregnancy may be viewed as a teachable moment: a time when women are receptive to health advice and take action to improve their health and the health of their babies. Pregnancy may also be a teachable moment for expectant fathers, although men's behaviors are rarely considered as part of prenatal care or in associated research. Design: Cross-sectional prevalence study. Sample: Rural low-income expectant fathers (N=138) whose pregnant partners had enrolled in a Medicaid managed care health plan. Measurement: A telephone survey measuring five health risk behaviors, sociodemographic variables, and pregnancy- and behavior change-related attitudes. Results: Analyses found the following: 49.3% smoked cigarettes; 30.4% engaged in hazardous drinking in the past month; 27.5% had very low physical activity levels; 94.9% had at-risk fruit/vegetable intake; and 42% had weight-related health risk (25.4% met body mass index [BMI] criteria for obesity). Further, 47.9% of the men engaged in three or more of five assessed health risk behaviors. Conclusions: This sample of expectant fathers engages in high rates of health risk behaviors. Failure to address the health risk behavior of men during prenatal care represents a missed opportunity to improve paternal, maternal, and family health. [source]

Trends in Alcohol-Related Traffic Risk Behaviors Among College Students

ALCOHOLISM, Issue 8 2010
Kenneth H. Beck
Background:, Alcohol-impaired driving is a major public health problem. National studies indicate that about 25% of college students have driven while intoxicated in the past month and an even greater percentage drive after drinking any alcohol and/or ride with an intoxicated driver. The purpose of this investigation was to examine the change in these various alcohol-related traffic risk behaviors as students progressed through their college experience. Methods:, A cohort of 1,253 first-time first-year students attending a large, mid-Atlantic university were interviewed annually for 4 years. Repeated measures analyses were performed using generalized estimating equations to evaluate age-related changes in prevalence and frequency of each behavior (i.e., ages 19 to 22). Results:, At age 19, 17%wt of students drove while intoxicated, 42%wt drove after drinking any alcohol, and 38%wt rode with an intoxicated driver. For all 3 driving behaviors, prevalence and frequency increased significantly at age 21. Males were more likely to engage in these behaviors than females. To understand the possible relationship of these behaviors to changes in drinking patterns, a post hoc analysis was conducted and revealed that while drinking frequency increased every year, frequency of drunkenness was stable for females, but increased for males. Conclusions:, Alcohol-related traffic risk behaviors are quite common among college students and take a significant upturn when students reach the age of 21. Prevention strategies targeted to the college population are needed to prevent serious consequences of these alcohol-related traffic risk behaviors. [source]

Outcome Expectancies and Risk Behaviors in Maltreated Adolescents

JOURNAL OF RESEARCH ON ADOLESCENCE, Issue 2 2006
Patrick Nickoletti
This study examined positive and negative outcome expectancies for risk behaviors, and their association with engagement in risk behaviors, in a sample of 149 maltreated adolescents. "Outcome Expectancies" are evaluative social cognitions about what will occur as a consequence of one's actions. Risk behaviors and outcome expectancies for substance use, sexual behavior, and delinquency were assessed. In all regression models, positive expectancies were significantly related to risk behaviors while negative expectancies, with one exception, were not significantly related. In three of four regression models, significant interactions were found between positive and negative expectancies in predicting risk behaviors. The nature of the interaction differed by type of risk behavior. Beyond demonstrating associations between outcome expectancies and risk behaviors in a maltreated sample, this paper contributes to the study of social information processing by demonstrating significant interactions between positive and negative expectancies.

The Association of Sexual Experience with Attitudes, Beliefs, and Risk Behaviors of Inner-City Adolescents

JOURNAL OF RESEARCH ON ADOLESCENCE, Issue 1 2006
Ellen Johnson Silver
We compared knowledge, attitudes, and demographic characteristics of 630 sexually experienced and 422 inexperienced inner-city adolescents aged 14,17 years. Sexual experience was associated with indicators of risk previously reported in the literature: male gender, older age, single-family home, smoking, drinking, and poorer academic performance. We found lower HIV knowledge in sexually inexperienced youth, which suggested an area of vulnerability compared with sexually active teens. However, most inexperienced adolescents intended to remain virgins for the next 6 months, most had peer groups they also perceived to be virgins, and they were more positive and confident about remaining abstinent. Differences between the groups suggest there may be benefits to developing intervention programs targeted to their different strengths and weaknesses. [source]

Beyond the "Model Minority" Stereotype: Trends in Health Risk Behaviors Among Asian/Pacific Islander High School Students

JOURNAL OF SCHOOL HEALTH, Issue 8 2009
Sung-Jae Lee PhD
ABSTRACT BACKGROUND: Asian/Pacific Islander (API) students have been stereotyped as the "model minority." The objective of this study was to examine the trends in health risk behaviors among API students who participated in the San Diego City Schools Youth Risk Behavior Survey (YRBS) between 1993 and 2005. METHODS: High school students from the San Diego City School District completed the self-administered YRBS between 1993 and 2005. Among sexually active students, logistic regression for survey data was used to examine trends in health risk behaviors. RESULTS: From 1993 to 2005, condom use at last sexual intercourse was consistently lower among API students than their cross-ethnic peers. We observed a significant increasing trend in lifetime smoking, drinking, and marijuana use. Parental communications regarding human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) were significantly less frequent and decreased over time. CONCLUSIONS: Our findings challenge the notion of API youth being the "model minority." API students face unique challenges, including barriers to good communication about sex and lower rates of condom use. School-based prevention programs are needed for API students, including a focus on HIV communication with parents. [source]

Associations Between Adolescent Risk Behaviors and Injury: The Modifying Role of Disability

JOURNAL OF SCHOOL HEALTH, Issue 1 2009
Sudha R. Raman PT
ABSTRACT BACKGROUND:, Adolescents with disabilities are at risk for poor health outcomes including injury. The objective of this study was to examine if disability status modifies the association between risk behavior and injury among adolescents. METHODS:, The cross-sectional Health Behavior in School-Aged Children Survey was administered to a representative sample of 7235 Canadian students (grades 6-10) in 2002. Students who reported at least 1 functional difficulty due to a health condition were classified as having a disability. Engagement in up to 6 individual risk behaviors and a summative multiple risk behavior score were considered the primary exposures. Primary outcomes included medically attended injury experienced during a 12-month period. RESULTS:, Sixteen percent of students reported a disability. Almost all risk behaviors and all injury outcomes were more common among students with disabilities than in those without disabilities (eg, older age group's smoking: 17.5% vs 8.9%, p = <.01; medically attended injury: 67.4% vs 51.4%, p = <.01). Clear risk gradients were observed between engagement in multiple risk behavior and all injury outcomes. The association between multiple risk behavior and injury was accentuated by disability status among older students, particularly for students with disabilities who engaged in frequent multiple risk behavior (adjusted risk ratio 1.8, 95% CI: 1.6-1.9). CONCLUSIONS:, Canadian students with disabilities who engage in risk behaviors experience higher risks for medically attended injury than their nondisabled peers who engage in those same risk behaviors. Injury prevention programs that focus on risk-taking behavior should integrate the needs of this high-risk group of adolescents in order to prevent additional disability. [source]

Effectiveness of Increasing Emergency Department Patients' Self-perceived Risk for Being Human Immunodeficiency Virus (HIV) Infected Through Audio Computer Self-interview,based Feedback About Reported HIV Risk Behaviors

ACADEMIC EMERGENCY MEDICINE, Issue 11 2009
Roland C. Merchant MD
Abstract Objectives:, Prior research has demonstrated that emergency department (ED) patient acceptance of human immunodeficiency virus (HIV) screening is partially dependent on patients' self-perceived risk of infection. The primary objective of this study was to determine the effectiveness of audio computer-assisted self-interview (ACASI)-based feedback. The intervention aimed to increase patient's self-perceived risk of being HIV infected by providing immediate feedback on their risk behaviors. Methods:, This 1-year, randomized, controlled trial at a U.S. ED enrolled a random sample of 18- to 64-year-old subcritically ill or injured adult patients who were not known to be HIV infected. All participants completed an anonymous, ACASI-based questionnaire about their HIV risk behaviors related to injection drug use and sex, as well as their self-perceived risk for being HIV infected. Participants were randomly assigned to one of two study groups: an intervention group in which participants received immediate ACASI-based feedback in response to each of their reported risk behaviors or a no-intervention group without feedback. Participants were asked to indicate their level of HIV risk on a five-point scale before and after they answered the questions. Change in level of self-perceived HIV risk was calculated and compared by study group using Pearson's chi-square test. An HIV risk behavior score that summarized reported HIV risk behavior was devised. Because HIV risk behaviors differ by sex, scores were calculated separately for each sex. Linear regression models that adjusted for study group and same subject covariance were employed to determine if higher HIV risk behavior scores were associated with an increase in self-perceived HIV risk. Results:, Of the 566 trial participants, the median age was 29 years (interquartile range [IQR] = 22,43 years), 62.2% were females, and 66.9% had been tested previously for HIV. After answering the reported HIV risk behavior questions, 12.6% of participants had an increase, 79.9% had no change, and 7.5% had a decrease in self-perceived HIV risk. Of the 46.6% of participants who initially indicated that they were not at risk for HIV, 11.4% had an increase in self-perceived HIV risk after answering the reported HIV risk behavior questions. Change in self-perceived HIV risk did not differ by study group (p = 0.77). There were no differences in reported HIV risk scores between the intervention and no-intervention groups for females (p = 0.78) or males (p = 0.86). In the linear regression models, a greater increase in self-perceived HIV risk was associated with higher reported HIV risk behavior scores for females (, = 0.59, 95% confidence interval [CI] = 0.15, 1.04) but not for males (, = 1.00, 95% CI = ,0.13 to 2.14). Conclusions:, Some ED patients can be moved, although modestly, to recognize their risk for being HIV infected by asking about their HIV risk behaviors. However, ACASI-based feedback messages about HIV risk behaviors do not increase subjects' self-perceived HIV risk. Female ED patients appear to increase their self-perceived HIV risk more than males when queried about their HIV risk behaviors. [source]

Concepts of Death Among Professional Alpine Climbers: Continuing Risk Behaviors in the Face of Death

ANTHROPOLOGY OF CONSCIOUSNESS, Issue 1-2 2000
Paul E. James II
Alpine climbing in the US has increased in popularity since the 1970s and despite the high objective risk involved it has continued to find new devotees. For professionals involved in this sport, the risks are encountered through near-death experiences and the real deaths of close friends. This essay uses interviews with climbers in the state of Washington, discussing their experiences with death, and uses written accounts. First, I discuss the many risks involved in climbing and how these risks are perceived and accepted by climbers. Next, 1 look at the immediate reaction to alpine deaths, and finally, to the long term effects on the lives and climbing practices of this group. Despite repeated confrontations with death, all informants continue exposing themselves to these risks. Every year more and more acquaintances die while the ideas and values that these climbers hold allow them to resist the fear of their own death and continue to climb. Keywords: death, risk-taking, sports. [source]

Dating Aggression and Risk Behaviors Among Teenage Girls Seeking Gynecologic Care

ACADEMIC EMERGENCY MEDICINE, Issue 7 2009
Lauren K. Whiteside MD
Abstract Objectives:, The objective was to describe rates of dating aggression and related high-risk behavior among teens presenting to the emergency department (ED) seeking gynecologic care, compared to those seeking care for other reasons. Methods:, Female patients ages 14,18 years presenting to the ED during the afternoon/evening shift of a large urban teaching hospital over a 19-month period were approached to participate and completed a self-administered computerized survey regarding sexual risk behaviors, past-year alcohol use, dating aggression, and peer aggression. Logistic regression analysis was used to identify factors associated with the evaluation of gynecologic complaint as noted by completion of a pelvic exam. Results:, A total of 949 teens were enrolled (87% response rate), with 148 receiving gynecologic evaluation. Among girls undergoing a gynecologic evaluation, 49% reported past-year dating aggression, compared to 34% of those who did not undergo gynecologic evaluation (odds ratio [OR] = 1.81, 95% confidence interval [CI] = 1.30 to 2.62). Logistic regression analysis predicting gynecologic evaluation found statistically significant variables to be older age (OR = 1.95, 95% CI = 1.24 to 3.06), African American race (OR = 1.58, 95% CI = 1.04 to 2.40), parental public assistance (OR = 1.64, 95% CI = 1.10 to 2.45), alcohol use (OR = 2.31, 95% CI = 1.57 to 3.38), and dating aggression (OR = 1.51, 95% CI = 1.03 to 2.21). Conclusions:, Of the teens undergoing gynecologic evaluation in this urban ED, 49% reported dating aggression. These teens also reported higher rates of other sexual risk behaviors compared to their peers. Care providers in urban EDs treating all female teens and particularly those seeking gynecologic care should be aware of this high rate of dating aggression and screen for aggression in dating relationships in this high-risk group.

HIV Transmission Risk Behaviors of Men and Women Living With HIV-AIDS: Prevalence, Predictors, and Emerging Clinical Interventions

CLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 1 2000
Seth C. Kalichman
This article reviews research on continued risk practices among individuals who know they are HIV infected. Across populations, one in three persons with HIV-AIDS continue practicing HIV transmission risk behaviors. Continued high-risk behaviors in persons with HIV are related to relationship factors, economic conditions, emotional states, substance abuse, and personality dispositions. High-risk behaviors are more likely with another infected person, but alarming rates of risk behaviors are observed with HIV-negative partners and partners of unknown HIV status. Risk practices are also affected by disclosure of HIV status and by perceptions of how anti-HIV medications may affect infectivity. New clinical models of intervention are needed to blend HIV prevention strategies with HIV-AIDS care services. [source]

Predictors of Residential Placement Following a Psychiatric Crisis Episode Among Children and Youth in State Custody

AMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 2 2009
Jung Min Park PhD
This study examined the extent and correlates of entry into residential care among 603 children and youth in state custody who were referred to psychiatric crisis services. Overall, 27% of the sample was placed in residential care within 12 months after their 1st psychiatric crisis screening. Among the children and youth placed in residential care, 51% were so placed within 3 months of their 1st crisis screening, with an additional 22% placed between 3 and 6 months after screening. Risk behavior and functioning, psychiatric hospitalization following screening, older age, placement type, and caregiver's capacity for supervision were associated with increased residential placement. The findings highlight the importance of early identification and treatment of behavior and functioning problems following a crisis episode among children and youth in state custody to reduce the need for subsequent residential placement. Having an inpatient psychiatric episode following a crisis episode places children at greater risk for residential placement, suggesting that the hospital is an important point for diversion programs. Children and youth in psychiatric crisis may also benefit from efforts to include their families in the treatment process. [source]

Risk behaviors for pesticide exposure among pregnant women living in farmworker households in Salinas, California

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 6 2004
Lisa Goldman MPH
Abstract Background Farmworkers and their families are at risk for pesticide exposure, however, little is known about behaviors that increase their risk. We determined the frequency of risky behaviors among pregnant farmworkers and characterized those at greatest risk. Methods Participants included 153 pregnant farmworkers and 248 pregnant non-farmworkers who resided with farmworkers from the CHAMACOS (Center for the Health Assessment of Mothers and Children of Salinas) study. We examined risky behaviors relating to handwashing, bathing, protective clothing, house cleaning, laundering of work clothes, wearing of work clothes and shoes into the home, and eating produce from the fields. Results Between 25 and 60% of women demonstrated risky behavior on each item. Practices of households with pregnant farmworkers and non-farmworkers did not differ. Women who lived in the United States longer, and in crowded households demonstrated the most risky behavior overall. Conclusions Pregnant farmworkers and those living with farmworkers need to be educated to reduce potential take-home pesticide exposure. Am. J. Ind. Med. 45:491,499, 2004. © 2004 Wiley-Liss, Inc.

Factors associated with incarceration and incident human immunodeficiency virus (HIV) infection among injection drug users participating in an HIV vaccine trial in Bangkok, Thailand, 1999,2003

ADDICTION, Issue 2 2009
Pravan Suntharasamai
ABSTRACT Aims To determine if incarceration was associated with human immunodeficiency virus (HIV) infection and identify risk factors for incarceration among injection drug users (IDUs) participating in an HIV vaccine trial in Bangkok. Design The AIDSVAX B/E HIV vaccine trial was a randomized, double-blind, placebo-controlled study. A proportional hazards model was used to evaluate demographic characteristics, risk behavior and incarceration as predictors of HIV infection and generalized estimation equation logistic regression analysis to investigate demographic characteristics and risk behaviors for predictors of incarceration. Setting The trial was conducted in Bangkok Metropolitan Administration drug-treatment clinics, 1999,2003. Participants A total of 2546 HIV-uninfected IDUs enrolled in the trial. Measurements HIV testing was performed and an interviewer-administered questionnaire was used to assess risk behavior and incarceration at baseline and every 6 months for a total of 36 months. Findings HIV incidence was 3.4 per 100 person-years [95% confidence interval (CI), 3.0,3.9] and did not differ among vaccine and placebo recipients. In multivariable analysis, being in jail (P < 0.04), injecting (P < 0.0001), injecting daily (P < 0.0001) and sharing needles (P = 0.02) were associated with HIV infection and methadone maintenance was protective (P = 0.0006). Predictors of incarceration in multivariable analysis included: male sex (P = 0.04), younger age (P < 0.0001), less education (P = 0.001) and being in jail (P < 0.0001) or prison (P < 0.0001) before enrollment. Conclusions Among IDUs in the AIDSVAX B/E trial, incarceration in jail was associated with incident HIV infection. IDUs in Thailand remain at high risk of HIV infection and additional prevention tools are needed urgently. HIV prevention services, including methadone, should be made available to IDUs. [source]

Time to clearance of human papillomavirus infection by type and human immunodeficiency virus serostatus

INTERNATIONAL JOURNAL OF CANCER, Issue 7 2006
Jill E. Koshiol
Abstract Persistent infection with high-risk human papillomavirus (HPV) is central to cervical carcinogenesis. Certain high-risk types, such as HPV16, may be more persistent than other HPV types, and type-specific HPV persistence may differ by HIV serostatus. This study evaluated the association between HPV type and clearance of HPV infections in 522 HIV-seropositive and 279 HIV-seronegative participants in the HIV Epidemiology Research Study (HERS, United States, 1993,2000). Type-specific HPV infections were detected using MY09/MY11/HMB01-based PCR and 26 HPV type-specific probes. The estimated duration of type-specific infections was measured from the first HPV-positive visit to the first of two consecutive negative visits. Hazard ratios (HRs) and 95% confidence intervals (CIs) for HPV clearance were calculated using Cox models adjusted for study site and risk behavior (sexual or injection drugs). A total of 1,800 HPV infections were detected in 801 women with 4.4 years median follow-up. HRs for clearance of HPV16 and related types versus low-risk HPV types were 0.79 (95% CI: 0.64,0.97) in HIV-positive women and 0.86 (95% CI: 0.59,1.27) in HIV-negative women. HRs for HPV18 versus low-risk types were 0.80 (95% CI: 0.56,1.16) and 0.57 (95% CI: 0.22,1.45) for HIV-positive and -negative women, respectively. HPV types within the high-risk category had low estimated clearance rates relative to low-risk types, but HRs were not substantially modified by HIV serostatus. © 2006 Wiley-Liss, Inc. [source]

Sexual behavior survey and screening for chlamydia and gonorrhea in university students in South Korea

INTERNATIONAL JOURNAL OF UROLOGY, Issue 2 2005
SEUNG-JU LEE
Abstract Background: The purpose of the present study was to define the prevalence of genital Chlamydia trachomatis and Neisseria gonorrhoeae infections and status of sexual risk behavior among university students (18,25 years old) in the capital region of South Korea. Methods: Participants filled out a self-administered questionnaire related to sexuality. First-void urine was analyzed for chlamydial and gonococcal infection by strand displacement amplification (BDProbTecET, BD Diagnostic Systems, MD). Results: A total of 622 students from 15 colleges in three universities took part in the study. The median age was 21 and 39.1% of them reported having sexual intercourse at least once. The prevalence of C. trachomatis among sexually active men and women was 8.4% and 10.6%, respectively. Gonococcal infection was noted in one symptomatic male. Factors significantly associated with infection were the number of sexual partners during past year and lifetime and condom use. Conclusions: This is the first sexually transmitted infection (STI) screening in university students in South Korea. Urine-based STI screening was both feasible and acceptable in university students in South Korea. It should be considered a routine part of programs to control STI nationally. [source]

Relationship Characteristics and Risk of HIV Infection: Rusbult's Investment Model and Sexual Risk Behavior of Gay Men in Steady Relationships,

Does Unrealistic Optimism Change Following a Negative Experience?,

JOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 6 2001
Frank P. Mkenna
One important counteracting force that may decrease the effects of unrealistic optimism is personal experience with threat. To examine this hypothesis, several groups were examined who had been exposed to varying degrees of threat. It was found that only those who had been exposed to the most severe threat (being hospitalized after a road accident) showed differential comparative risk estimates from those who had experienced no threat. Differences between these two groups were also found for their self-reported risk behavior. The generality of the debiasing effect was assessed by examining risk perceptions in other domains. It was found that the effect was domain specific. [source]

Heterogeneity in patterns of sexual risk behaviors among african-american youth: Associations with general and race-specific factors

JOURNAL OF COMMUNITY PSYCHOLOGY, Issue 4 2007
Anthony L. Burrow
This descriptive study employed a within-groups analytic approach to examine patterns of sexual risk behavior and co-occurring general and race/ethnicity-specific risk and protective factors in a community sample of African-American youth (n = 436). Cluster analysis was used to classify young adults by levels of self-reported past year sexual risk behaviors. MANOVA, ANOVA, and chi-square analyses indicated significant associations between cluster membership and (a) lifetime psychiatric diagnoses, (b) peer substance use behaviors, and (c) self-reported past year alcohol and marijuana use. Cluster membership was not associated with several race/ethnicity-specific variables: racial/ethnic orientation, cultural mistrust, and perceived discrimination. The results of the current study can inform the development of HIV/STI prevention strategies for vulnerable African-American youth. © 2007 Wiley Periodicals, Inc. J Comm Psychol 35: 447,462, 2007.

Impact of beliefs about HIV treatment and peer condom norms on risky sexual behavior among gay and bisexual men

JOURNAL OF COMMUNITY PSYCHOLOGY, Issue 1 2006
John L. Peterson
The association between perceptions about condom use among one's peers, beliefs about new HIV treatments, and HIV sexual risk behavior was examined in a large urban sample ( N = 454) of gay and bisexual men in the Southeast. Results partially confirmed the hypothesis that men who endorsed new HIV treatment beliefs would report lower norms for condom use and higher HIV sexual risk behaviors than men who failed to endorse HIV treatment beliefs but with casual, and not main, partners. Moreover, results confirmed the hypothesis that the association between HIV treatment beliefs and unprotected sex would be partially mediated by peer condom norms. Results suggest social interventions are needed to promote condom norms in the social context of new HIV treatments. © 2006 Wiley Periodicals, Inc. [source]

Clinicopathological features and immunohistochemical expression of p53, Ki-67, Mcm-2 and Mcm-5 in proliferative verrucous leukoplakia

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 6 2010
Adriele Ferreira Gouvêa
J Oral Pathol Med (2010) 39: 447,452 Background:, Proliferative verrucous leukoplakia (PVL) is a distinct and aggressive type of oral leukoplakia which affects elderly women without risk behavior and presents high rates of malignant transformation. The objective of the present study was to evaluate the clinicopathological characteristics and the distribution of cell proliferation markers, aiming to elucidate the distinct biological behavior of the PVL. Methods:, Clinical and microscopical features of 12 patients with PVL were reviewed. Immunohistochemical analysis for p53, Ki-67, Mcm-2 and Mcm-5 were performed and the data were correlated. Results:, All patients were women, above 50 years of age, 91.7% were non-smoker and 100% were non-habitual drinker. Alveolar ridge (66.6%), tongue (50%) and buccal mucosa (41.6%) were the most affected sites. Four patients developed squamous cell carcinoma (SCC). The immunohistochemical findings showed higher positivity for p53, Ki-67, Mcm-2 and Mcm-5 in SCCs. However, some patients with mild or moderate dysplasia, specially the patients who developed SCC, presented high expression of Mcm-2 and Mcm-5. Conclusions:, High immunoexpression of Mcm-2 and Mcm-5 in mild and moderate dysplasia could be helpful to predict the malignant transformation of PVL. [source]
