High-risk Sexual Behavior (high-risk + sexual_behavior)
Selected AbstractsSex under the Influence of Drugs or Alcohol: Common for Men in Substance Abuse Treatment and Associated with High-Risk Sexual BehaviorTHE AMERICAN JOURNAL ON ADDICTIONS, Issue 2 2010Donald A. Calsyn PhD Sex under the influence of drugs or alcohol is associated with high-risk sexual behavior. Heterosexual men (n = 505) in substance abuse treatment completed a computer-administered interview assessing sexual risk behaviors. Most men (73.3%) endorsed sex under the influence in the prior 90 days, and 39.1% endorsed sex under the influence during their most recent sexual event. Sex under the influence at the most recent event was more likely to involve anal intercourse, sex with a casual partner, and less condom use. Patients might benefit from interventions targeting sexual behavior and substance use as mutual triggers.,(Am J Addict 2010;00:1,9) [source] Seroprevalence, risk factors, and hepatitis C virus genotypes in groups with high-risk sexual behavior in CroatiaJOURNAL OF MEDICAL VIROLOGY, Issue 8 2009Tatjana Vilibic Cavlek Abstract The seroprevalence, risk factors and genotypes of hepatitis C virus (HCV) in groups with high-risk sexual behavior (persons with multiple sexual partners, men who have sex with men, commercial sex workers and their clients and persons with sexually transmitted diseases) in seven Croatian cities were analyzed. A total of 821 participants without history of injecting drug use were included in the study. Anti-HCV prevalence among risk groups varied from 2.9% to 8.5% with an overall prevalence of 4.6% (95% CI,=,3.2,6.1) compared with 0.5% (95% CI,=,0.0,1.5) in controls (pregnant females; OR,=,9.66; 95% CI,=,1.32,70.7). HCV-RNA was detected in 73.1% anti-HCV positive patients. Three of the seronegative cases (2.1%) were also found to be HCV-RNA positive ("window period"). Genotype 1 was most commonly detected (55.6%). The most prevalent subtypes were 1a (38.9%) and 3a (38.9%). Sociodemographic characteristics (age, gender, marital status and level of education) were not associated with anti-HCV seropositivity. Among sexually transmitted disease markers, a higher seroprevalence of HCV infection was found in subjects with a history of HBV infection (10.5% vs. 3.8%, P,=,0.002) and gonorrhea (13.2% vs. 4.2%, P,=,0.011). No other factors reflecting risk sexual behavior such as sexual orientation, number of sexual partners and number of risk behaviors were associated with HCV seroprevalence. J. Med.

[source] Serotyping and genotyping of HIV-1 infection in residents of Khayelitsha, Cape Town, South AfricaJOURNAL OF MEDICAL VIROLOGY, Issue 12 2006G.B. Jacobs Abstract It is estimated that between 5.5 and 6.1 million people are infected with HIV/acquired immunodeficiency syndrome (AIDS) in South Africa, with subtype C responsible for the majority of these infections. The Khayelitsha suburb of Cape Town has one of the highest HIV prevalence rates in South Africa. Overcrowding combined with unemployment and crime in parts of the area perpetuates high-risk sexual behavior, which increases exposure to infection by HIV. Against this background, the objective of this study was to characterize HIV-1 in residents confirmed to be seropositive. Serotyping was performed through a competitive enzyme-linked immunosorbent assay (cPEIA). Genotyping methods included RNA isolation followed by RT-PCR and sequencing of the gag p24, env gp41 immunodominant region (IDR), and env gp120 V3 genome regions of HIV-1. With the exception of a possible C/D recombinant strain, all HIV-1 strains were characterized as HIV-1 group M subtype C. One individual was shown to harbor multiple strains of HIV-1 subtype C. In Southern Africa, the focus has been to develop a subtype C candidate vaccine, as this is the major subtype found in this geographical area. Therefore, the spread of HIV-1 and its recombinant strains needs to be monitored closely. J. Med. Virol. 78:1529,1536, 2006. © 2006 Wiley-Liss, Inc. [source] High Prevalence of Sexually Transmitted Infections Among Young Peruvians Who Have Sexual Intercourse With Foreign Travelers in CuzcoJOURNAL OF TRAVEL MEDICINE, Issue 5 2009Miguel M. Cabada MD Background Sexual networking in popular tourist destinations is a problem worldwide. In Peru, locals sexually interacting with travelers bridge high-risk groups, the general population, and travelers. Methods A cross-sectional study was conducted in Cuzco about sexual behavior among young Peruvians who admitted having sex with travelers. A subgroup of the participants had serologic testing for Chlamydia trachomatis, Herpes simplex virus (HSV) type 2, and Treponema pallidum. Results Eighty-eight subjects volunteered for blood sampling. Their mean age was 22.9 years (±4.1) and 53.4% were male. The majority were single (86.2%), but 12.6% had a stable relationship. The median number of sexual partners in the 3 months prior to the study was 2 [interquartile range (IQR): 1,4]. During that period, 43.1% reported foreign partners, 28.4% reported foreign and Peruvian partners, 17% reported Peruvian partners, and the remaining 11.5% reported combinations of Peruvian, foreign, and sex workers partners. The median number of foreign partners in the 12-month period prior to the study was 4 (IQR: 2,8). Only 25.3% reported consistent condom use. Alcohol (69%) and drugs (36.8%) were commonly used before sexual activity. Seventy-eight percent tested positive for HSV type 2, 25% for C trachomatis, and 1.1% for T pallidum. Conclusions The core group of young Peruvians we report on demonstrated a high-risk sexual behavior and a high prevalence of sexually transmitted infections. Our results underscore the need for education on safer sex practices among this group and among travelers.

[source] Implications of Racial and Gender Differences In Patterns of Adolescent Risk Behavior for HIV And Other Sexually Transmitted DiseasesPERSPECTIVES ON SEXUAL AND REPRODUCTIVE HEALTH, Issue 6 2004Carolyn 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] | ||||||||||
