Risk behaviors related to human immunodeficiency virus (HIV) infection and transmission were studied in a sample of 167 male cocaine users admitted during a 5-month period to an inpatient drug treatment program. Data obtained included drug history and related behaviors, sexual behaviors, knowledge, and attitudes regarding HIV infection and AIDS. Approximately 20% of the sample had used IV drugs in the year prior to the interview and 94% of these reported sharing needles; 20% of the IV drug users (IVDUs) reported always using bleach to clean needles. With regard to sexual practices, 7% of the total sample reported sex with other males in the year prior to the interview; 86% of the total sample reported having sex with females and 80% of these noted they never or rarely used condoms during vaginal sex. Respondents generally did not believe they themselves were at high risk for HIV infection, yet they continued to engage in acknowledged high-risk behaviors. These findings suggest that IVDUs and non-IV cocaine users are likely to contribute to the spread of HIV in several populations.  相似文献

This study aimed to evaluate the prevalence of sexually transmitted infections (STIs) and associated risk factors in HIV-infected pregnant women followed for prenatal care in Salvador, Bahia. This was a cross-sectional study of 63 women seeking prenatal care at a reference center. Participants were interviewed regarding socio-epidemiological and clinical history, and were tested for HBsAg, anti-HCV, anti HTLV I/II, VDRL, Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma hominis, Ureaplasma urealyticum, CD4 count, and HIV plasma viral load. The main outcome variable was the presence of any STI. The mean age of patients was 28.2 years (16-40 years). 23 (36.5%) were diagnosed with at least one STI. The frequency of diagnoses was: HBV, 3.2%; HCV, 8.1%; HTLV I/II, 3.4%; syphilis, 9.5%; Chlamydia trachomatis, 11.1%; HPV, 15.0%; Mycoplasma hominis, 2.1%, and Ureaplasma urealyticum, 2.1%. No case of Neisseria gonorrhoeae was identified. No association was found between socio-epidemiological variables and the presence of an STI. CD4 T lymphocyte < 500 cells/μL (p = 0.047) and plasma viral load >1,000 copies (p = 0.027) were associated with the presence of STI. STIs are frequent in pregnant women infected with HIV, and all HIV-infected pregnant women should be screened to decrease transmission of these pathogens and to protect their own health.  相似文献

Two hundred and forty male and 9 female jail inmates confined for various crimes in a district jail near Delhi were screened for sexually transmitted and blood-borne diseases including HIV, syphilis and hepatitis B and C viral infections, skin diseases etc. The inmates were aged 15-50 years with a mean of 24.8+/-0.11. Their alleged criminal background, period of stay in the jail, drug addiction, education, birth place, marital status, sexual activity, and clinical complaints were recorded by an anonymous questionnaire. Serum samples were tested for antibodies against HIV (1+2), hepatitis C (HCV), Treponema pallidum and for hepatitis B surface antigen (HBsAg). Sputum examination was done for acid-fast bacilli. Out of the 240 men, 115 were married and 125 unmarried. One hundred and eighty-four (76.6%) men gave history of penetrative sex. Of the 184, 53 (28.8%) were homosexuals or bisexuals and 131 (71.2%) had sex with women only. Sixty of the 131 (45.8%) were faithful to their partners while 124 gave a history of having multiple sexual partners and 100 of them (80.6%) had unprotected sex. Eighty-three of these 100 also had had sex with commercial sex workers (CSWs). One hundred and twenty-six were addicted for alcohol, 44 for smack/charas and 8 had a history of intravenous drug abuse. One hundred and seventy-four were not aware of AIDS. On examination 28 of the 240 (11.6%) had active hepatitis with or without a history of jaundice in the last 2 years, 25 (10.4%) active pulmonary tuberculosis (TB) and 11 (4.6%) had syphilitic ulcers on the penis. Four-fifths of the teenagers confined to a particular barrack had moderate to severe scabies. Three males (1.3%) were found to be Western blot confirmed HIV-1 positive while 28 (11.1%) men and 2 (22.2%) women were positive for HBsAg. Twelve (5.0%) men but no women, were found to be positive for anti-HCV antibodies. Out of the 3 HIV-positive persons, one was an intravenous drug user (IVDU), second was a drug addict and frequent CSW visitor while the third was a homosexual. This pilot study gives an indication that sexually transmitted and blood-borne infections are highly prevalent in jail premises and pose a threat of rapid spread of these infections through IVDU and homosexuality.  相似文献

OBJECTIVES: To determine the prevalence of major sexually transmitted infections (STIs) and gynaecological morbidity in women of reproductive age living in rural communities in north-east Brazil and to assess risk factors associated with the presence of STIs. METHODS: A total of 341 women (84%) were examined gynaecologically and colposcopically. The gynaecological history was taken by means of a standardized, pre-tested questionnaire. Cervical smears were obtained and vaginal fluid was collected. Vulvovaginal candidiasis (VC), bacterial vaginosis (BV), trichomoniasis (TV) and syphilis seroreactivity were determined by standard laboratory techniques. Infections with Neisseria gonorrhoeae, Chlamydia trachomatis and human papilloma virus (HPV) were diagnosed by hybrid capture assays using vaginal lavage fluid. Odds ratios (OR) were calculated to assess risk factors associated with STIs. RESULTS: The prevalence of HPV, BV and TV was 26%, 15% and 10%, respectively. VC as well as infections with N. gonorrhoeae and C. trachomatis were detected in 6%; syphilis seroreactivity, in 3%. Multiple infections were very common, and 51% of women had at least one STI. Vaginal discharge, the predominant morbidity (56%), was significantly associated with BV (OR = 6.3; P < 0.001), vulvovaginal itching with VC (OR = 3.5; P < 0.05) and lower abdominal pain with C. trachomatis infection (OR = 2.6; P < 0.04). Colpitis was diagnosed in 27% of women and significantly associated with TV (OR = 3.5%; P < 0.001) and VC (OR = 2.9; P < 0.05). Being unmarried was a significant risk factor for having an STI (OR = 2.4; P < 0.05). Among unmarried women, age (<20 years) was a significant risk factor (OR = 3.3; P = 0.01). CONCLUSIONS: The STIs are highly prevalent in this female population in the rural hinterland of north-east Brazil and associated with considerable morbidity. In view of the expected spread of HIV from the urban centres at the coast to the interior there is an urgent need for providing STI-related health care and health education for adolescents and women in rural Brazil.  相似文献

A survey was carried out in 2 drug use treatment centres (TCs) in Rio de Janeiro, Brazil, to assess risk behaviours, HIV infection and other sexually transmitted infections/blood-borne infections (STIs/BBIs). Two hundred and twenty-five drug users (195 males and 30 females) were interviewed and clinically examined, and their blood and urine were tested for STIs/BBIs. Prevalences (%) for these infections were as follows--HIV: 0.9, hepatitis B virus (HBV): 14.7, hepatitis C virus (HCV): 5.8, syphilis: 5.3, gonorrhoea/chlamydia (CT/NG): 4.7. In bivariate analyses CT/NG infection was associated with younger age (P=0.003); current genitourinary symptoms (odds ratio [OR]=6.2) and a mainly illegal source of income (OR=9.1). Hepatitis C infection was associated with a history of ever having injected any drug (OR=19.6), and with each one of the injected drugs. After multiple logistic regression, lower educational level (adjusted odds ratio [AOR]=3.70) and 'ever having injected drugs' (AOR=3.69) remained as independent risk factors for hepatitis B infection. In conclusion, TCs must implement programmes directed towards the prevention of STIs/BBIs.  相似文献

This study assessed the epidemiology of sexually transmitted infections (STIs), HIV, and associated risk factors among female sex workers (FSWs) in Guangxi autonomous region, China. A cross-sectional study of 488 FSWs was conducted using a structured questionnaire to collect sociodemographic and behavioral information. Biological specimens from subjects were sampled to detect various STIs and HIV infection. Among FSWs, the prevalence rates of syphilis, Neisseria gonorrhoeae, Chlamydia trachomatis, genital herpes, condyloma acuminate, and HIV were 7.2%, 1.8%, 18.2%, 0.4%, 2.3%, and 0.8%, respectively. The prevalence rates of single, double, and triple infections were 22.3%, 3.9%, and 0.20%, respectively. Multivariate analysis indicated that STIs and HIV infection was independently related to low education level (OR = 7.244; 95% CI = 3.031-17.213; P < 0.001), low knowledge of STIs/HIV (OR = 0.191; 95% CI = 0.108-0.337; P < 0.001), low-grade working place (OR = 1.64; 95%CI = 1.016-2.648; P = 0.046), and no condom use during the last sexual intercourse (OR = 0.199; 95% CI = 0.113-0.350; P < 0.001). The prevalence of STIs is high among FSWs in Guangxi, is accompanied by a 0.8% HIV-positive rate, and may be largely related to high-risk sexual behaviors. Future interventions should be focused on the reduction of risk factors, including promotion of condom use and improvement of knowledge of STIs and HIV among FSWs.  相似文献

The HIV epidemic in Estonia is rapidly expanding, and injection drug users (IDUs) are the major risk group contributing to the expansion. A convenience sample of 159 IDUs visiting syringe-exchange programmes (SEPs) was selected to quantify the association of HIV-risk behaviours and blood-borne infections. A high prevalence of HIV, hepatitis B core antibody (HBVcore), hepatitis B surface antigen (HbsAg) and hepatitis C virus antibodies (56, 85.1, 21.3, and 96.2%, respectively) was associated with high-risk injections, unsafe sexual behaviour and alcohol abuse. These findings emphasize the importance of evidence-based secondary prevention among the HIV-infected, especially given the uncertain sustainability of antiretroviral and substance abuse treatments.  相似文献

To better understand the prevalence, incidence, and risk factors for sexually transmitted diseases (STDs) among female adolescents, a prospective 6-month cohort study was conducted at four teen clinics in a southeastern city. At enrollment, 260 (40%) of 650 sexually active females ages 14-19 years had an STD: chlamydia, 27%; herpes simplex virus type 2 (HSV-2), 14%; gonorrhea, 6%; trichomoniasis, 3%; and hepatitis B, 2%. At follow-up, 112 (23%) of 501 participants had an incident infection: chlamydia, 18%; HSV-2, 4%; gonorrhea, 4%; and trichomoniasis, 3%. At either enrollment or follow-up, 53% had >/=1 STD; of those with 1 lifetime partner, 30% had an STD. Having a new partner (odds ratio [OR], 2.2; 95% confidence interval [CI], 1. 1-4.2) or friends who sell cocaine (OR, 1.6; CI, 1.0-2.6) was independently associated with incident infection. STD incidence and prevalence were extremely high in this population, even in teenagers with only 1 lifetime partner. Individual risk behaviors appeared less important for STD risk than population factors.  相似文献

A cross-sectional survey was conducted of sexually transmitted diseases (STDs) and risky behaviors among 407 drug abusers in treatment facilities in 1998. Infections with human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), herpes simplex virus type 2 (HSV-2), and syphilis were detected by testing serum antibody levels; chlamydia and gonorrhea were detected by testing nucleic acid levels in urine. Logistic regression analysis was performed to measure associations. Prevalences of antibodies were as follows: to HSV-2, 44.4%; to HCV, 35.1%; to HBV, 29.5%; to HIV, 2.7%. The prevalence of syphilis was 3.4%; of chlamydia, 3.7%; and of gonorrhea, 1.7%. Of the 407 subjects, approximately 62% had markers for 1 of the STDs. HIV infection was associated with African American race, use of smokable freebase (crack) cocaine, and STD history. HBV infection was associated with age >30 years, injecting drugs, needle sharing, a history of treatment for drug abuse, and African American race. HCV infection was associated with an age >30 years, injecting drugs, and needle sharing, and HSV-2 infection with an age >30 years, female sex, and African American race. Syphilis was associated with a history of STDs. High prevalences of STDs among drug abusers indicate the need for integration of STD screening and treatment into drug treatment programs.  相似文献

Women in prison have a higher prevalence of HIV than men. After release from prison, former inmates have the opportunity to engage in risk behaviors for HIV and other sexually transmitted infections (STIs). We sought to assess change in risk behaviors over time and the association of gender with risk behavior in the postrelease period. In this prospective cohort study, we interviewed 200 former inmates (51 women) approximately two weeks (baseline) and three months (follow-up) after release and tested them for HIV infection at follow-up. We examined the association of gender with unprotected vaginal or anal sex in the last seven days using chi-square and Fisher's exact tests and multivariable logistic regression. At baseline, 22% of men and 41% of women reported unprotected vaginal sex (p < 0.01) and 5% of men and 8% of women reported unprotected anal sex (p = 0.51). Being younger (OR for each decade increase 0.48, 95% CI = 0.29–0.80), being gay/lesbian or being bisexual (compared with being heterosexual, OR = 4.74, 95% CI = 1.01–22.17 and OR = 3.98, 95% CI = 1.41–11.26, respectively), or reporting a drug of choice of heroin/speedballs or cocaine/crack (compared with marijuana/no drug of choice, OR = 24.00, 95% CI = 5.15–111.81 and OR = 3.49, 95% CI = 1.20–10.18, respectively) was associated with unprotected vaginal or anal sex after adjusting for race, homelessness, and hazardous drinking. At follow-up, 21% of men and 44% of women reported unprotected sex (p = 0.005), and female gender (OR = 4.42, 95% CI = 1.79–10.94) and hazardous drinking (compared with not meeting criteria for hazardous drinking, OR = 3.64, 95% CI = 1.34–9.86) were associated with unprotected sex, adjusting for race and homelessness. In this population with a high prevalence of HIV, we demonstrated persistent engagement in sexual risk behavior during the postrelease period. Enhanced efforts to promote sexual health and reduced risk behavior among both male and female current and former prison inmates are needed, including improved access to preventive care and HIV and STI screening, testing, and treatment.  相似文献

Injection drug users (IDUs) are the vanguard of the human immunodeficiency virus (HIV) epidemic in Russia. We sought a non-invasive method to estimate a point prevalence of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis and risk behaviours in IDUs attending the syringe exchange programme (SEP) in St Petersburg, Russia. One hundred and one IDUs returning syringes to the St Petersburg SEP were invited to complete a questionnaire requesting demographic, knowledge, and behavioural information, and to provide their syringes for antibody testing. The median age of IDUs was 23 years. Syringe prevalences were: 10.9% for HIV, 78.2% for HCV, 15.8% for HBV, and 6.9% for syphilis. All respondents recognized drug-related risk factors for getting AIDS. Only two-thirds of subjects recognized condoms to prevent sexually transmitted infections and half knew that oil-based lubricants are not appropriate for condoms. The IDU population studied was young and requires additional interventions to encourage safer sexual behaviours.  相似文献

Female sex workers (FSW) are at greater risk for HIV and STIs. A systematic literature review of HIV and STI prevalence and incidence data for FSW in China was conducted to assess current trends. Studies between 1996 and 2010 detailing seroprevalence or incidence data, other laboratory-based tests, and clinical diagnoses of infections among FSW were reviewed. Select articles from Chinese literature around street-based and drug-abusing FSW were also reviewed. Results revealed high median prevalence for a variety of STIs among FSW: active syphilis range 0.8-12.5% (median = 6.9%), herpes range 29.7-70.8% (median = 56.2%), chlamydia range 3.9-58.6% (median = 25.7%), gonorrhea range 2.0-85.4% (median = 16.4%), and trichomoniasis range 7.1-43.2% (median = 12.5%). HIV prevalence has remained relatively low and stable with a range of 0-10.3% (median = 0.6%), with the exception of higher prevalence in several areas of Yunnan and some areas of Guangxi. The FSW who are injecting drug users may be at even greater risk for HIV infection with 12-49% found to be HIV positive and 7-25% self-reporting positive status. A number of gaps in the literature remain, especially in the number of studies that detail prevalence confirmed by laboratory testing or that collect incidence data. Assessment of incidence and prevalence according to sampling methodology appropriate for the population, behavioral risks such as injecting drug use, and diverse venues especially those at the lower end are needed. Theory-based interventions to reduce the incidence and prevalence of HIV/STIs need to be piloted with successful models scaled-up.  相似文献

BACKGROUND: While several studies have reported on sexual risk behaviours and the prevalence of sexually transmitted infections (STIs) among injection drug users (IDUs), there are fewer prospective studies that have been able to examine populations of IDUs with no history of STIs. Therefore, the authors examined prevalence, correlates and factors associated with time to first STI infection in a prospective cohort of IDUs in Vancouver, British Columbia. METHODS: The authors examined the prevalence and correlates of STIs among IDUs at the time of recruitment into a prospective cohort study. The authors also evaluated the cumulative rate of time to first STI among IDUs with no history of STIs at baseline using the Kaplan-Meier method, and modelled factors independently associated with first STI using Cox regression. RESULTS: Between May 1996 and November 2003, 1560 individuals were recruited into the cohort; of these individuals, 745 reported a history of STI at baseline. Among the 815 who did not report an STI at baseline, 671 (82%) had at least one follow-up visit and were eligible for the analysis of time to first STI. After 36 months of follow-up, the cumulative rate of first STI was 8.2% for men and 15.9% for women (log-rank P<0.001), whereas the cumulative rate of first STI was 8.0% for IDUs who did not report sex trade involvement versus 19.8% for IDUs who reported sex trade involvement (log-rank P<0.001). In multivariate analyses, the risk of first STI remained independently associated with unprotected sex with regular partners (relative hazard=2.04, 95% CI 1.29 to 3.23; P=0.001) and unprotected sex with sex trade clients (relative hazard=2.36, 95% CI 1.46 to 3.82; P=0.005). CONCLUSIONS: In the present study, the authors found that STIs were associated with both regular sex partnerships and sex trade involvement. These findings are of particular concern because both unprotected sex with regular partners and sex trade involvement is common among IDUs. Interventions to encourage condom use among IDUs, particularly those with regular sex partners and those involved in the sex trade, should be further developed.  相似文献

The goal of this study was to explore gender difference in HIV-related perceptions according to a social cognitive theory and sexual risk behaviors and to examine associations between mobility, sexual risk, and history of sexually transmitted diseases (STDs) among male and female migrants visiting STD clinics. A cross-sectional study among migrants visiting STD clinics in three large cities in China assessed HIV-related perceptions, sexual activity, condom use, and history of STDs was used. Among participants, 20% of women had ever sold sex and 33% of men had paid for sex. Women and men were similar in multiple partnerships in the last month (23% versus 22%), consistent condom use during last three sexual encounters (14% versus 15%), and a history of STDs (57% versus 53%). However, more women who reported a history of STDs had contracted at least two STDs than men (55% versus 36%, p < 0.001). Increased sexual risk was associated with increased perception of extrinsic rewards for both genders, but was associated with increased perceptions of intrinsic rewards and response cost in women only, and with decreased perceptions of vulnerability and response efficacy in men only. High mobility was associated with increased sexual risk in women. Self-reported history of STDs was associated with a high rate of past multiple partnership and low education among both genders, but was associated with high mobility and commercial sex in women only. Fifty-four percent of women with a history of STDs informed their partners about their infections, compared to 36% of men (p < 0.001). Married women, both women and men who did not engage in commercial sex, and women and men who used condoms were more likely to inform their partners about their STD infections. Gender differences in HIV-related perceptions and sexual behaviors underscore the importance of gender-specific intervention efforts to prevent the spread of HIV/STD in China.  相似文献

Sexually transmitted infections (STIs) have shown to enhance the transmission of human immunodeficiency virus (HIV) and to be more common among female commercial sex workers (FSWs). A cross-sectional study was conducted among 625 FSWs in six cities of Argentina in 2000-2002. The seroprevalence of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), human T-cell lymphotropic virus type I/II, and syphilis was 3.2%, 14.4%, 4.3%, 1.6%, and 45.7%, respectively. Syphilis was associated with older age (>/= 30 years, adjusted odds ratio [AOR] = 2.6 to 4.9), >/= 10 years in sex work (AOR = 2.2), use of illegal drugs (AOR = 2.1), and a prior history of an STI (AOR = 3.0). HBV and syphilis was the most common co-infection in 44 (7.5%) subjects. FSWs in Argentina are exposed to HIV and other STIs due to high-risk sexual and illegal drug use behavior. Renewed efforts are necessary to intervene effectively in this high-risk population.  相似文献

Three hundred and six sexually experienced adolescents participated in a study on sexually transmitted infection (STI) prevalence and associated risk factors. The prevalence of Neisseria gonorrhoea (NG), Chlamydia trachomatis (CT), Trichomonas vaginalis (TV) and syphilis was 4.5%, 9%, 8% and 4% for females and 4.7%, 5.7%, 0% and 2.8% for males. HIV-seropositivity was found in 15.2% of females and 5.8% of males. Structured face-to-face interviews were used to obtain information about social background, sexual experience and genital symptoms. Four focus-group discussions were used in order to validate the interview data. Females were more likely to be infected by the four treatable STIs and HIV, despite risky behavior being more common among males. Unemployment, little formal education, the presence of bacterial STIs and post-coital bleeding or a bad smell from the vagina was highly associated with the risk for HIV in females. The higher prevalence of STIs, including HIV, among adolescent girls cannot be explained by sexual behavior only, as boys reported more risk behavior and were still less affected by STIs. Biological and social factors are definitely of importance.  相似文献

Interviews were conducted with 137 female sex partners of male injection drug users to provide quantitative and qualitative information regarding their AIDS knowledge, attitudes, and specific risk behaviors. Levels of knowledge regarding HIV transmission and prevention were high, with an average of 81.8% correct on a 16-item test. Most women (87.5%) believed that there was at least some chance they would become HIV infected. Substance abuse was prevalent; 67.2% used non-injection drugs (44.5% used crack cocaine), and 32.1% reported prior use of injection drugs. One fifth had engaged in prostitution. Although AIDS knowledge was high, almost all (94.9%) reported engaging in unprotected vaginal intercourse during the previous 6 months, and 6.6% reported anal intercourse without a condom. Among women who did not report consistent condom use, the most frequently stated reasons for non-use of condoms were dislike by their male partner (26.9%) and/or personal dislike of condoms (23.1%). A disturbing pattern of increased risk was observed among black interviewees, who were more likely than Latinas or whites to have contracted syphilis, have multiple sex partners, engage in prostitution, use crack cocaine, and drink alcohol daily.  相似文献

Aims Follow‐up studies show that smokers, alcoholics and heroin addicts have high mortality rates, but there is little information on crack users. We have investigated the mortality rate among this population, including its risk factors and causes of death. Design A 5‐year follow‐up study. Participants and setting A cohort of 131 crack‐dependent patients, admitted to a public detoxification unit in São Paulo between 1992 and 1994. Measurements Data collected from a structured personal interview and from a review of patients’ hospital records, confirming the deaths from records held at the Municipal Offices. Findings Of the 124 (94.6%) patients located, 23 (18.5%) had died (a mortality ratio of 7.6). Homicide was the most common cause of death (n = 13). Observed mortality rate, adjusted for age and sex, was 24.92 per 1000, while the expected all‐cause mortality rate in São Paulo, also adjusted for age and sex, was 3.28 per 1000, giving an excess mortality rate of 21.64 per 1000. Survival analysis showed that the probability of being alive 5 years post‐treatment was 0.80 (95% CI = 0.77–0.84). Cox's proportional hazards regression showed three factors predicted mortality: history of intravenous drug use (hazard ratio 3.28, 95% CI 1.42–7.59), unemployment at index admission (hazard ratio 3.48, 95% CI 1.03–11.80) and premature discharge from index admission (hazard ratio 2.21, CI 0.94–5.18). Conclusions Community‐based and tailored interventions should be considered to improve those patients’ social support and permanence in treatment.  相似文献
