Childhood sexual abuse, adolescent sexual behaviors and sexual revictimization.

OBJECTIVE: The aims of this study were to examine the extent to which exposure to childhood sexual abuse (CSA) was associated with increased rates of sexual risk taking behaviors and sexual revictimization during adolescence. METHOD: A birth cohort of 520 New Zealand born young women was studied at regular intervals from birth to the age of 18. At age 18 retrospective reports of CSA were obtained from sample members. Over the course of the 18 year study information was gathered on: (a) childhood, family, and related circumstances; and (b) the young women's history of sexual experiences from 14 to 18 years. RESULTS: Young women reporting CSA, and particularly severe CSA involving intercourse, had significantly higher rates of early onset consensual sexual activity, teenage pregnancy, multiple sexual partners, unprotected intercourse, sexually transmitted disease, and sexual assault after the age of 16. Logistic regression analyses suggested that the associations between CSA and sexual outcomes in adolescence arose by two routes. First, exposure to CSA was associated with a series of childhood and family factors including social disadvantage, family instability, impaired parent child relationships, and parental adjustment difficulties that were also associated with increased sexual vulnerability in adolescence. Second, there appeared to be a causal chain relationship between CSA and sexual experiences in which CSA was associated with early onset sexual activity which, in turn, led to heightened risks of other adverse outcomes in adolescence. CONCLUSIONS: The findings of this study suggest that those exposed to CSA have greater sexual vulnerability during adolescence. This appears to arise because: (a) the childhood and family factors that are associated with CSA are also associated with increased sexual risks during adolescence; and (b) exposure to CSA may encourage early onset sexual activity which places those exposed to CSA at greater sexual risk over the period of adolescence.

[Prevalence of asymptomatic sexually transmitted infections among high-risk patients attending a free anonymous HIV-screening center].

INTRODUCTION: The aim of this study was to assess the prevalence of sexually transmitted infections among patients attending an anonymous HIV Screening Center. PATIENTS AND METHODS: This prospective study was performed in the HIV Screening Center of University hospital in Reims (France) from May 1997 to December 1997. The inclusion criteria were the asymptomatic clinical presentation and the presence of risk factors for sexually transmitted infections referring to WHO criteria. The methods included clinical examination after application of acetic acid and urethral and endocervical swabs to identify:Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma hominis, Gardnerella vaginalis, Trichomonas vaginalis in specific culture. Treponema pallidum and HIV-1 infection were both detected by Enzym Linked Immuno Sorbent Assay (ELISA). RESULTS: One hundred and one patients (62 men and 39 women) were included in the study. Their mean age was 27 +/- 4 Years. Risk factors for sexually transmitted infections were: multiple sexual partners 81 p. 100; homo or bisexuality 16 p. 100; intravenous drug use 3 p. 100. The sexually transmitted infections were: HIV-1 infection 1 p. 100;Ureaplasma urealyticum 25 p. 100; genital warts 5 p. 100;Chlamydia trachomatis 3 p. 100; Gardnerella vaginalis 3 p. 100; Mycoplasma hominis 2 p. 100; Treponema pallidum 0 p. 100; Neisseria gonorrhoeae 0 p. 100; Trichomonas vaginalis 0 p. 100. The prevalence of sexually transmitted infections was significantly higher among women (p<0.05). DISCUSSION: Classical sexually transmitted infections and HIV infection were rarely detected in this study; but prevalence of other sexually transmitted infections (genital warts, Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum) was high. Ureaplasma urealyticum is considered as a possible pathogenic agent in pregnant women (preterm delivery, decrease of birth weight, chorioamniotitis). These results suggest that other than sexually transmitted infections in high risk patients attending a HIV Screening Center other sexually transmitted infections should also be systematically screened for.

The impact of the hepatitis B mass immunisation campaign on the incidence and risk factors of acute hepatitis B in Italy.

BACKGROUND/AIMS: This study aimed to evaluate the impact of the campaign for hepatitis B mass immunisation of children and teenagers, introduced in 1991, on the incidence of and risk factors for hepatitis B in Italy. METHODS: Hepatitis B cases reported to the surveillance system for type-specific acute viral hepatitis (SEIEVA) during the period 1987-1997 were used to estimate incidence. To assess the association between potential risk factors and hepatitis B cases, hepatitis A cases generated by the same surveillance system were used as controls. RESULTS: During the period 1987-1997, 8275 acute hepatitis B cases were reported to SEIEVA. Hepatitis B incidence declined from 10.4/100,000 in 1987 to 2.9/100,000 in 1997. The fall was more evident before than after the introduction of compulsory vaccination against hepatitis B. The results of multivariate analysis showed that during the years 1995-1997, blood transfusion, intravenous drug use, surgical intervention, dental therapy, other parenteral exposures, multiple sexual partners, and being in the household of a chronic HBsAg carrier were all exposures independently associated with hepatitis B. CONCLUSIONS: The strong association linking acute hepatitis B with iatrogenic exposures, which are more common in adults, suggests that the present immunisation strategy should be combined with the implementation of non-immunologic preventive measures.

Influence of psychosocial factors on adolescent compliance with oral contraceptives.

This paper prospectively tests the influence of a variety of sociomedical and psychosocial factors on compliance with oral contraceptives among adolescent females from a population at high risk for pregnancy. Fifty-six females aged 14-19 yr from a lower socioeconomic background received a battery of pretest measurements and were then given Ortho-Novum 1/35 combined with riboflavin during an initial visit and 1-, 2-, and 4-month follow-ups. Compliance was measured at each follow-up using a Guttman scale consisting of: (1) avoidance of pregnancy, (2) appointment adherence, (3) pill count, and (4) urinary fluorescence for riboflavin. Six factors were found to be significantly associated with noncompliance: (1) multiple sexual partners, (2) appointment being made by the adolescent, (3) low evaluation of personal health, (4) feelings of hopelessness, (5) worry about becoming pregnant, and (6) previous abortion. These findings suggest that certain indicators of sexual activity and social psychological status may help predict noncompliance in some adolescent females.

HIV risks among homeless men differentiated by cocaine use and psychiatric distress.

This study examined the relationship among cocaine use, psychiatric distress, and HIV risk behaviors of homeless men. A 3 x 2 ANOVA was computed to determine overall mean HIV risk behavior, with the first factor representing three levels of psychiatric distress (low, moderate, and high) and the second factor representing use or no use of cocaine. Overall, homeless men who used cocaine had significantly higher HIV risk scores than did noncocaine users. Among the homeless men who used cocaine, those men who reported high psychiatric distress had significantly higher HIV risk scores than did noncocaine users and cocaine users with low psychiatric distress. Moreover, these risk scores predominantly represented three high risk sexual behaviors; lack of condom use, multiple sex partners, and participation in commercial sex. Outreach efforts that target both substance use and especially high-risk sexual practices are urged for this population.

Monogamy in lizards.

Monogamy is relatively rarely reported in taxa other than birds. The reproductive system of many lizard species appears to involve multiple mating partners for both the male and the female. However, short-term monogamous relationships have been reported in some lizard species, either where the male defends a territory that is only occupied by a single adult female, or where males stay with females for a period of time after mating, apparently to guard against rival males. There are a few reported cases of more prolonged monogamous relationships in lizards, with the Australian sleepy lizard, Tiliqua rugosa, the best studied example. Adult males and females of this species form monogamous pairs for an extended period before mating each spring, and they select the same partner in successive years. The paper reviews possible functions of monogamy in this and other lizard species, and suggests that the additional perspective from studying lizards may enrich our overall understanding of monogamous behaviour.

Correlates of heavy substance use among young gay and bisexual men: The San Francisco Young Men's Health Study.

Correlates of heavy substance use among a household-based sample of young gay and bisexual men (n=428) were identified and the odds ratio (OR) was calculated. A total of 13.6% reported frequent, heavy alcohol use and 43% reported polydrug use. Compared with men employed in professional occupations, men in service positions (OR=3.77) and sales positions (OR=2.51) were more likely to be heavy alcohol consumers. Frequent gay bar attendance and multiple sex partners were related to heavy alcohol use, as well as to polydrug use. Polydrug users were more likely to be HIV seropositive (OR=2.05) or of unknown HIV serostatus (OR=2.78). HIV serostatus was similarly related to frequent drug use. These correlates of heavier substance use among young gay and bisexual men could be used to identify and intervene early with members of this population who are at risk of substance misuse, as well as HIV/AIDS risk.

Lifetime correlates associated with amphetamine use among northern Thai men attending STD and HIV anonymous test sites.

AIMS: To investigate the demographic, sexual, and other substance use risk correlates of amphetamine use among men in northern Thailand prior to the current epidemic of amphetamine use in the Kingdom. DESIGN: Cross-sectional quantitative behavioral questionnaires. SETTING: Thai Ministry of Health STD and HIV Anonymous Test Sites in the upper northern provinces of Chiang Mai and Lamphun. PARTICIPANTS: Adult Thai men recruited at clinics for enrollment in an HIV seroincidence cohort study (The Thai HIVNET). All men were HIV negative at enrollment, and had at least one self-reported sexual risk for HIV infection (a recent STD, use of sex workers, multiple sexual partners, low or absent condom use, sex with men). MEASUREMENTS: Participants answered a structured questionnaire. FINDINGS: Lifetime history of amphetamine use was reported by 133/914 men, 14.5%. Older age was protective for use (odds ratio (OR) 0.5) and use was associated with use of other substances; heroin (OR 7.1), thinner (OR 6.2), opium (OR 5.9), and marijuana (OR 5.7). Several STDs were associated with amphetamine use: gonorrhea (OR 2.3) and genital warts (OR 2.4), and any STD (OR 1.9). In multivariate analysis, use of heroin (OR 3.1), soft drugs (OR 4.9), and a history of gonorrhea (OR 2.0) were independently associated with amphetamine use in northern Thai men. CONCLUSIONS: Associations between young age, gonorrhea, other substance use and amphetamines indicate that prevention measures could occur at STD clinics and be incorporated into school programs when individuals are entering adolescence.

Screening for sexually transmitted infections in substance abuse treatment programs.

OBJECTIVES: We evaluated the prevalence of the sexually transmitted infections (STIs) chlamydia and gonorrhea in clients at a methadone maintenance program and a residential detoxification program. METHODS: We collected urine specimens for chlamydia and gonorrhea ligase chain reaction testing and assessed sexual, substance abuse and STI histories. RESULTS: Of 700 subject assessments, 490 occurred among detoxification clients and 210 in methadone maintenance. Chlamydia trachomatis was detected in 5/700 (0.9, 95% CI=0.1-1.8%) and Neisseria gonorrhoeae in none. All chlamydia infected subjects were recruited from the detoxification program. Subjects reported high risk sexual behavior: 17% reported commercial sex exchange, and 22% reported inconsistent condom use with multiple sexual partners during the prior 2 months. CONCLUSION: Based on prevalence in Boston, MA, universal screening for STI in substance abuse treatments programs is not warranted. However, routine screening for younger substance abusers and in communities with high prevalence should be considered.

The relationship between risk networks' patterns of crack cocaine and alcohol consumption and HIV-related sexual behaviors among adult injection drug users: a prospective study.

Social context may be an important determinant of drug and alcohol consumption and HIV-related behaviors. To assess the influence of peers on drug users' risk behaviors this study examined the association between individual level and group level behaviors. This analysis reports on the prospective association between baseline self-reported drug and alcohol use of the network members of injection drug users, and self-reported sexual behaviors and alcohol use at 5-month follow-up. Participants were a nontreatment sample of inner-city injection drug users who volunteered for a network-oriented HIV preventive intervention. They were predominantly unemployed, African American males. Of the 71 index participants who completed both the baseline and follow-up interviews, 227 of their drug network members were enrolled in the study. At baseline indexes' sexual risk behaviors were significantly associated with their drug network members' level of crack cocaine use. At follow-up higher levels of alcohol and crack use among drug network members were associated with indexes' reports of multiple sex partners and increased alcohol consumption. Higher levels of crack use among the drug network members were associated with the indexes' reporting casual sex partners at follow-up. These results highlight the importance of studying the role of peer group influence and the social context of risk behaviors.

Cocaine users with antisocial personality improve HIV risk behaviors as much as those without antisocial personality.

Previous work has documented that antisocial personality disorder (APD) is associated with increased rates of HIV risk behaviors and with worse substance abuse treatment outcomes. The question addressed by this paper is whether cocaine users with APD respond to an HIV risk-reduction intervention as well as cocaine users without the disorder. The study subjects were 333 cocaine users followed up at 18 months as part of a NIDA-funded treatment demonstration project. The total sample improved across a wide range of HIV risk behaviors. Improving significantly (P < 0.05) from baseline to the 18-month follow-up were several drug-related behaviors: cocaine use; current cocaine dependence; use of drugs other than cocaine drug injection; injection equipment sharing; and use of syringes that were not cleaned. Several sex-related HIV risk behaviors also improved significantly: having multiple sex partners; being intoxicated during sex; giving drugs for sex; receiving money for sex; and receiving drugs for sex. When the sample was stratified by APD status, very similar improvement was seen in respondents with and without APD. To examine further the relationship of APD to change in HIV risk behaviors, separate logistic regression models of improving and worsening HIV risk behaviors were tested. What the authors found was no association of APD with improvement in HIV risk behaviors but a significant association of APD with worsening HIV risk behaviors. It appears that cocaine users with APD improve their HIV risk behaviors just as much as those without APD but may be at higher HIV risk for the development of such behaviors.

[Knowledge of hepatitis B and C among underprivileged people].

BACKGROUND: Prevalence for hepatitis B (HBV) and C (HCV) viruses infection are particularly high among underprivileged persons (UPP) related to the use of injecting drug, residence in high endemic countries or a low rate of condom use in case of multiple sexual partners. It is important to know whether these persons are well aware of prevention measures for these infections. The aim of our study was to evaluate the knowledge of preventive measures among UPP and, at the same time, among health- and social-care workers (H/S-CWs). METHODS: The study was conducted in 68 salvation settings. The H/S-CWs filled out once 9-item self-administered questionnaires on HBV and HCV, concerning the illnesses, and their transmission, prevention, and screening. A similar questionnaire was proposed by H/S-CWs, to UPP after each interview. All answers were grouped into 4 categories: true (one right item or more), false, unknown, no answer. RESULTS: One thousand nine hundred twenty one questionnaires were collected: 312 were from H/S-CWs and 1609 from UPP. The answer rate was 100% for H/S-CWs and 92.7% among the UPP population. Knowledge about HBV and HCV was better for H-CWs compared to S-CWs. For HBV, routes of transmission was the best known field (85.2% of right answers) and use of blood sample screening was the least known field (54.2%). Vaccination was advanced by 50.6% of H/S-CWs. For HCV, routes of transmission were also the best known field (65.9%) while preventive measures were frequently unknown (22.0%). Among the UPP, blood sample screening was the best known field for HBV (34.5% of right answers) as for HCV (27.5%). Knowledge about the routes of transmission and the populations at risk was very low for HBV (28.2% and 15.5%) and for HCV (9.4% and 5.1%). The analyses of each response showed that the rates of wrong answers were much higher for H/S-CWs compared to UPP. On the other hand the rates of "unknown" answer were higher in the UPP. This finding suggests that H/S-CWs had a false perception of knowing relevant information on HBV and HCV. The high proportion of no answer among UPP confirmed their ignorance of those diseases. CONCLUSION: The UPP needs appropriate information on HBV and HCV. This information could be delivered by H/S-CWs. However, preliminary training, particularly for S-CWs, might improve their insufficient knowledge at the present time.

Seroprevalence of hepatitis B and hepatitis C among rural emergency medical care personnel.

To identify the prevalence of serologic markers of hepatitis B and hepatitis C among rural prehospital providers, a prospective descriptive study was conducted of a rural county emergency medical services (EMS) system. Participants included 107 prehospital care providers: 102 EMT-Bs, 1 paramedic, and 4 law enforcement first responders. Blood samples taken from prehospital care providers were tested for hepatitis B surface antigen (HBsAg), antibody to HBsAg (HBsAb), antibody to hepatitis B core antigen (HBcAb), and antibody to hepatitis C (anti-HC). The 107 providers had a total of 635 years of EMS experience (5.93 years per subject). Three providers (3%) had received previous blood transfusions, 7 (7%) had worked in a metropolitan area, and 6 (6%) had multiple sexual partners prior to the study. No provider reported intravenous drug use or known homosexual or bisexual contact. Only one sample tested positive for hepatitis C antibody (anti-HC) and hepatitis surface antibody (HBsAb). Rural prehospital care personnel have a low prevalence (0.9%) of exposure to hepatitis B and hepatitis C. Despite this fact, continued vigilance should be maintained in preventing transmission of bloodborne illnesses.

Delivery of HIV risk-reduction services in drug treatment programs.

This study examined services received for HIV risk reduction among individuals in drug treatment. Analyses were conducted using data from 4,412 participants in the national Drug Abuse Treatment Outcome Study (DATOS), a prospective multisite study of drug treatment effectiveness. A higher percentage of individuals in long-term residential programs received HIV-related services, compared with clients in short-term inpatient, methadone maintenance, and outpatient drug-free programs. More men than women, and individuals at higher sex-risk as compared with those at lower sex-risk, received HIV services. Logistic regression analyses indicated that individuals who engaged in sex work had a higher likelihood than those who did not, of receiving HIV-related services, although individuals with high-risk or multiple sexual partners were no more likely than others to receive HIV services. More comprehensive service delivery is needed in order to reduce the risk for HIV among clients in drug treatment.

Relapse outcomes in a randomized trial of residential and day drug abuse treatment.

Relapse outcomes at 6-, 12-, and 18-month intervals were compared between clients randomly assigned to day (n=114) versus residential (n=147) drug abuse treatment. Day clients were more likely than residential clients to relapse 6 months post-admission (OR=3.06, p<0.001); however, no setting differences at 12 or 18 months were found. Few baseline predictors were prospectively related to relapse at 12 and 18 months. These predictors were usual employment status (part-time OR=17.47, p<0.001; full-time OR=2.54, p<0.001), history of drug injecting (OR=5.39, p<0.01), multiple sex partners (OR=1.16, p<0.01), and not having a gay sexual partner (OR=0.05, p<0.03) during 6 months prior to admission. Still, these baseline predictors, together with the existing literature, could be used by drug treatment professionals to identify individuals who may be at high risk for relapse over time, and to offer specialized treatment and aftercare resources as intervention and prevention measures.

Motivations associated with methamphetamine use among HIV+ men who have sex with men.

Previous research has documented an association between methamphetamine (meth) use and high-risk sex among HIV- men who have sex with men (MSM); however, little is known about the sexual risk behaviors of HIV+ meth-using MSM. The purpose of this study was to explore personal motivators of meth use among HIV+ MSM, and to elaborate upon the interaction between meth use and risky sex. Thematic analysis of qualitative data from 25 HIV+ MSM revealed meth use was associated with high rates of anal sex, low rates of condom use, multiple sex partners, sexual marathons, and anonymous sex. Personal motivations associated with meth use included: sexual enhancement; and self-medication of negative affect associated with HIV+ serostatus. A variety of treatment approaches are used to describe how client insights into motivations can be used by clinicians to promote change in drug use and sexual risk behavior.

Alcohol-exposed pregnancy: characteristics associated with risk.

BACKGROUND: Prenatal alcohol exposure is a leading cause of neurodevelopmental deficits in children. Women who are fertile, drink alcohol, and have unprotected intercourse are at risk for an alcohol-exposed pregnancy, but little is known about this population. METHODS: A survey was administered to 2672 English-speaking women aged 18 to 44 years from six settings, including an urban jail, a drug/alcohol treatment facility, a gynecology clinic, two primary care clinics, and respondents to a media solicitation. Bivariate and multivariate analyses were conducted to explore variables that were correlated with membership in the at-risk group. RESULTS: Most respondents (70%) reported a household income of <$20,000; 68% had a high school or equivalent education; and 62% were African American. A total of 333 women (12.5%) met the a priori definition of "at risk" for an alcohol-exposed pregnancy. Stepwise logistic regression showed that recent drug use (odds ratio [OR]=3.1; 95% confidence interval [CI]=2.1-4.4); having smoked more than 100 cigarettes (OR=1.9, 95% CI=1.3-2.7); a history of inpatient treatment for drugs or alcohol (OR=1.8, 95% CI=1.3-2.4) or inpatient mental health treatment (OR=1.6, 95% CI=1.1-2.3); having multiple sex partners (OR=1.7, 95% CI=1.2-2.2); and recent physical abuse (OR=1.5, 95% CI=1.1-2.0) were significantly correlated with being at risk. CONCLUSIONS: It was possible to identify diverse settings with an increased prevalence of women at risk for an alcohol-exposed pregnancy. Within these settings, women at risk were characterized by an increased frequency of selected behaviors. This information may help clinicians develop and target interventions prior to conception.

HIV infection: a retrospective analysis of adolescent high-risk behaviors.

INTRODUCTION: The purpose of this study was to retrospectively ascertain behaviors and activities that may constitute high risk during the adolescent years (ages 12-18) of young adults (ages 20-25) who are infected with human immunodeficiency virus (HIV). METHODS: Subjects (n = 44) from 1 of 5 clinics in a large midwestern city completed a survey form, developed by the investigators, which examined 6 areas of behavior and activities that the literature suggested may be associated with high-risk behaviors. RESULTS: The adolescent high-risk profile of an HIV-infected young man includes sexual abuse before the age of 12 years, heavy consumption of alcohol, heavy consumption of a variety of illicit drugs, a wide variety of sexual experiences at very young ages, and multiple sexual partners. The adolescent high-risk profile of an HIV-infected young woman in this study includes heavy consumption of alcohol, heavy consumption of a variety of illicit drugs, and unprotected vaginal intercourse at very young ages as evidenced by a high number of sexually transmitted diseases at very young ages. DISCUSSION: Although the small number of participants in this study restricts interpretation of the results, adolescent health initiatives should be examined in light of these findings. Programs and services must consider the context of psychosocial situations, as well as past experiences, and incorporate this knowledge into prevention strategies.
