Incident Chlamydia trachomatis infections among inner-city adolescent females.

CONTEXT: Adolescents are at highest risk for infection with Chlamydia trachomatis, an important preventable cause of pelvic inflammatory disease and subsequent tubal factor infertility in US women. Current guidelines for delivery of adolescent primary care services recommend yearly chlamydia screening for those adolescent females considered to be at risk. OBJECTIVES: To describe the epidemiology of prevalent and incident chlamydia infection among adolescent females to assess the appropriate interval for chlamydia screening and to define risk factors that would identify adolescent females to target for screening. DESIGN: Prospective longitudinal study. PATIENTS: A consecutive sample of 3202 sexually active females 12 through 19 years old making 5360 patient visits over a 33-month period, January 1994 through September 1996. SETTING: Baltimore, Md, family planning, sexually transmitted disease, and school-based clinics. INTERVENTION: Testing for C trachomatis by polymerase chain reaction. MAIN OUTCOME MEASURES: Prevalence and incidence of C trachomatis infections; predictors of positive test result for C trachomatis. RESULTS: Chlamydia infection was found in 771 first visits (24.1%) and 299 repeat visits (13.9%); 933 adolescent females (29.1%) had at least 1 positive test result. Females who were 14 years old had the highest age-specific chlamydia prevalence rate (63 [27.5%] of 229 cases; P=.01). The chlamydia incidence rate was 28.0 cases per 1000 person-months (95% confidence interval, 24.9-31.5 cases). The median time was 7.2 months to a first positive chlamydia test result and 6.3 months to a repeat positive test result among those with repeat visits. Independent predictors of chlamydia infection--reason for clinic visit, clinic type, prior sexually transmitted diseases, multiple or new partners, or inconsistent condom use-failed to identify a subset of adolescent females with the majority of infections. CONCLUSIONS: A high prevalence and incidence of C trachomatis infection were found among adolescent females. We, therefore, recommend screening all sexually active adolescent females for chlamydia infection every 6 months, regardless of symptoms, prior infections, condom use, or multiple partner risks.

Sexually transmissible diseases and travel.

Sexually transmissible diseases (STDs) continue to be the most common notifiable infectious conditions worldwide. Their unacceptably high incidence is underlined by the recent emergence of a (presently) incurable and lethal STD, human immunodeficiency virus (HIV) infection, which merits its description as a pandemic, and with which other STDs interact in an epidemiological synergy. Certain travellers, by virtue of their behavioural interactions with 'core-groups' of efficient transmitters, may have a high relative risk of acquisition of an STD. This risk can be virtually eliminated by avoiding penetrative sexual intercourse with casual partners, especially injecting drug users and persons who have had multiple sexual partners (particularly prostitutes), or reduced by the use of condoms. The risk of parenteral exposure can be reduced by avoiding parenteral drug use and behaviour that is likely to lead to injury and by seeking facilities with adequate capabilities to screen blood donors and to sterilize instruments.

Sex in Australia: safer sex and condom use among a representative sample of adults.

OBJECTIVE: To provide reliable estimates of the frequency of condom use and correlates of condom use among Australian adults. METHODS: Computer-assisted telephone interviews were completed by a representative sample of 10,173 men and 9,134 women aged 16-59 years. The response rate was 73.1% (69.4% men, 77.6% women). RESULTS: Although the majority of respondents had used a condom at some time in their lives, fewer than half of the respondents who were sexually active in the year before being interviewed had used a condom in the past year. Condom use in the past year was associated with youth, greater education, residence in major cities, lower incomes, white-collar occupations, being a former smoker, and having more sexual partners in the past year. In the six months prior to interview, 7.1% of respondents always used condoms with regular cohabiting partners, 22.5% always used condoms with regular non-cohabiting partners, and 41.4% always used condoms with casual partners. Approximately 20% of respondents used a condom the last time they had vaginal intercourse, and one in eight of these condoms were put on after genital contact. Condom use during the most recent sexual encounter was associated with youth, living in a major city, having a lower income, having sex with a casual partner, and not using another form of contraception. CONCLUSION: As in other studies, condom use was strongly associated with partner type and use of other contraception. IMPLICATIONS: People with multiple sexual partners need to be aware that non-barrier methods of contraception (and condoms applied late) do not protect against sexually transmitted infections.

AIDS-related risk perception and sexual behaviour among sexually transmitted disease clinic attenders.

Perception of risk has been suggested as an important element of sexual behaviour change among people who engage in behaviours which place them at risk of HIV infection. A study of the relationship between perception of risk of HIV infection and risk-related sexual behaviours was conducted in a genitourinary medicine clinic. The sample comprised 767 patients attending over a 3-month period; data collection was by self-completed questionnaire. A total of 574 questionnaires were suitable for analysis, representing a response rate of 75%. The majority of people in the sample reported behaviours which increased their risk of HIV infection, but only 19% (n = 112) of the sample perceived themselves to be personally 'at risk', despite adequate knowledge of HIV transmission and methods of risk reduction. Significant differences between social class groups were found for knowledge scores, with highest scores among professionals and lowest among unemployed subjects (Kruskal Wallis test chi 2 = 24.6, P less than or equal to 0.001). Increasing age was significantly associated with better knowledge; significantly more young people aged 16-20 years who did not perceive themselves 'at risk' (64%), had lower knowledge scores than older people who did not perceive themselves 'at risk' (41%). Among heterosexuals who reported having sex with other people in addition to their regular partner, 79% did not perceive themselves as 'at risk' of HIV infection, and of these, 64% reported only infrequent condom use with casual sexual partners. Significantly more heterosexual men (67%) than women (44%) reported multiple sex partners.(ABSTRACT TRUNCATED AT 250 WORDS)

Frequency and correlates of intimate partner violence by type: physical, sexual, and psychological battering.

OBJECTIVES: This study estimated the frequency and correlates of intimate partner violence by type (physical, sexual, battering, or emotional abuse) among women seeking primary health care. METHODS: Women aged 18 to 65 years who attended family practice clinics in 1997 and 1998 took part. Participation included a brief in-clinic survey assessing intimate partner violence. Multiple polytomous logistic regression was used to assess correlates of partner violence by type. RESULTS: Of 1401 eligible women surveyed, 772 (55.1%) had experienced some type of intimate partner violence in a current, most recent, or past intimate relationship with a male partner; 20.2% were currently experiencing intimate partner violence. Among those who had experienced partner violence in any relationship, 77.3% experienced physical or sexual violence, and 22.7% experienced nonphysical abuse. Alcohol and/or drug abuse by the male partner was the strongest correlate of violence. CONCLUSIONS: Partner substance abuse and intimate partner violence in the woman's family of origin were strong risk factors for experiencing violence. Efforts to universally screen for partner violence and to effectively intervene to reduce the impact of such violence on women's lives must be a public health priority.

Factors associated with pediculosis pubis and scabies.

OBJECTIVE: To ascertain factors associated with genital pediculosis and scabies infestations among attenders at an STD clinic. DESIGN: Cross sectional assessment of potential risk factors by multiple logistic regression. SETTING: A central city sexually transmitted diseases (STD) clinic in Adelaide, South Australia. SUBJECTS: All men and women patients attending from 1988 to 1991. RESULTS: Pediculosis pubis was diagnosed in 205 of 12,170 (1.7%) men and 65 (1.1%) of 6125 women, and scabies in 56 (0.5%) men and 6 (0.1%) women attending an STD clinic from 1988-1991. Independent risk factors by multivariate analysis for pediculosis pubis in women were pregnancy (odds ratio (OR) = 2.3), sex outside the state (OR = 2.2) and age under 25 (OR = 2.0). Many factors were associated with pediculosis pubis in men, including no steady partner (OR = 1.4), multiple partners (OR = 1.6), being unmarried (OR = 2.0) and homosexual behaviour (OR = 1.6). None of these factors was associated with scabies infestation which was strongly associated with being Aboriginal (OR = 6.8) and being unemployed (OR = 2.5). CONCLUSION: In this setting scabies appears to be determined by socioeconomic factors and pediculosis pubis predominantly by sexual activity factors.

Health risks and opportunities for harm reduction among injection-drug-using clients of Saskatoon's needle exchange program.

Information about injection drug users' lifestyles is necessary to develop effective harm reduction strategies. One way to gather this information is through needle exchange programs. In 1998, a convenience sample of 100 clients of Saskatoon's needle exchange service was interviewed about their injection and sexual practices. Ritalin and morphine were the most commonly injected drugs. Over half the participants (53%) reported having shared needles, usually with friends, relatives, and partners. Slightly more (62%) had shared injection equipment. Most participants had multiple sexual partners, especially the women, half of whom were sex trade workers. Condom use was higher with casual partners than with regular partners. While awareness about HIV transmission was high, most participants considered their risk of infection to be below average. These findings are discussed in light of the insights they provide regarding both health risks and opportunities for harm reduction in the study population.

Assessment of sexual behavior, sexual attitudes, and sexual risk in Sweden (1989-2003).

To assess changes in sexual behavior, sexual attitudes, and sexual risk related to HIV, we conducted mailed questionnaire surveys in random samples of the Swedish general population in 1989, 1994, 1997, 2000, and 2003 (total N = 13,762). Each sample consisted of 4,000-6,000 subjects aged 16-44 years, stratified by age: 16-17, 18-19, 20-24, 25-34, and 35-44 years. The overall participation rate was 63.8% (for men, 55.9%; for women, 71.9%). The prevalence of three or more sexual partners and casual sexual contacts without the use of a condom was comparatively high for men, for persons aged 16-24 years, single persons with and without a regular partner, and persons living in towns and urban areas. The prevalence of multiple sexual partners and casual sexual contacts increased significantly over time. There was a significant decrease in the proportion of participants who agreed with the statement "Sexual intercourse should only take place in a stable relationship." Personal risk assessments related to HIV did not change significantly over time. The study shows that risky sexual behavior related to HIV/AIDS increased in the Swedish population between 1989 and 2003, and that attitudes concerning casual sexual relations became more permissive.

Why are young college women not using condoms? Their perceived risk, drug use, and developmental vulnerability may provide important clues to sexual risk.

BACKGROUND: Young multiethnic college women (YMCW) are at risk for STDs and HIV secondary to high-risk sexual behaviors that are related to developmental issues such as invincibility, low perceived risk, and substance use. METHOD: One hundred YMCW on a southern California university campus completed surveys that examined variables that impacted their sexual risk. RESULTS: The study yielded many significantly correlated variables. Women with low perceived risk, lower use of drugs and alcohol, and who had parental involvement had lower sexual behavior risk. Women that were sexually assertive, had intentions to use condoms, and did not use substances used condoms more often. Older students in advanced grades who had steady partners used substances less and had decreased sexual risk, however, they experienced partner resistance to condoms, which canceled out any reduced risk. In a multiple regression analysis, condom use intention and substance use predicted condom use, perceived risk and substance use predicted sexual behavior risk. White women had significantly higher substance use, perceived sexual risk, and sexual behavior risk than did Latinas and African Americans. CONCLUSIONS: Despite their assertiveness and intentions, many participants had multiple sexual partners, and 64% of the YMCW were inconsistent condom users. Despite knowing the elevated risks, 52% used drugs and alcohol during sex. Negative attitudes (61%) about condoms were also demonstrated as a key factor in the lack of condom use.

Sexual abuse and reproductive health among unmarried young women seeking abortion in China.

OBJECTIVE: To investigate sexual violence and its impact on reproductive health in unmarried young women seeking abortion in China. METHODS: A total of 2002 participants were surveyed by questionnaire, gynecologic examination, and laboratory tests for sexually transmitted disease (STD). RESULTS: Overall, 14% of participants had experienced sexual violence and 43.4% were diagnosed with STD. Among victims of sexual abuse, 8.6% had their first sexual encounter when they were younger than 18 years; 42.7% had had 2 or more sexual partners; and 21.6% never used contraception. Multivariate analysis revealed that sexual abuse, multiple sexual partners, sexual activity before the age of 18 years, and not using contraception were important indicators of the presence of STD. CONCLUSION: The prevalence of sexual abuse is high in China; and among unmarried young women seeking abortion, those who experience sexual abuse are at significantly increased risk for STD.

A comparison of HIV seropositive and seronegative young adult heroin- and cocaine-using men who have sex with men in New York City, 2000-2003.

The purpose of this analysis was to determine the prevalence and correlates of HIV infection among a street-recruited sample of heroin- and cocaine-using men who have sex with men (MSM). Injection (injecting <or=3 years) and non-injection drug users (heroin, crack, and/or cocaine use <10 years) between 18 and 40 years of age were simultaneously street-recruited into two cohort studies in New York City, 2000-2003, by using identical recruitment techniques. Baseline data collected among young adult men who either identified as gay/bisexual or reported ever having sex with a man were used for this analysis. Nonparametric statistics guided interpretation. Of 95 heroin/ cocaine-using MSM, 25.3% tested HIV seropositive with 75% reporting a previous HIV diagnosis. The majority was black (46%) or Hispanic (44%), and the median age was 28 years (range 18-40). HIV-seropositive MSM were more likely than seronegatives to be older and to have an HIV-seropositive partner but less likely to report current homelessness, illegal income, heterosexual identity, multiple sex partners, female partners, and sex for money/drug partners than seronegatives. These data indicate high HIV prevalence among street-recruited, drug-using MSM compared with other injection drug use (IDU) subgroups and drug-using MSM; however, lower risk behaviors were found among HIV seropositives compared with seronegatives. Large-scale studies among illicit drug-using MSM from more marginalized neighborhoods are warranted.

A tale of two sexually transmitted diseases. Prevalences and predictors of chlamydia and gonorrhea in women attending Colorado family planning clinics.

BACKGROUND: The comparative prevalences and predictors of chlamydia and gonorrhea have not been studied in the family planning clinic population. GOALS: To determine the comparative prevalences and predictors of chlamydia and gonorrhea among Colorado family planning clinic patients. STUDY DESIGN: Cross-sectional study of public and private family planning clinic patients in Colorado tested for both chlamydia and gonorrhea (n = 12,926). RESULTS: Among women tested for both infections, the chlamydia prevalence rate was 4.5% and the gonorrhea prevalence rate was 0.5%. Multivariate analysis showed that independent predictors of chlamydia were age younger than 25 years, black or Hispanic race-ethnicity, cervical friability, mucopus, exposure to a sex partner with chlamydia, or multiple recent sex partners. Independent predictors of gonorrhea were age younger than 20 years, black or Hispanic race-ethnicity, or exposure to a sex partner with gonorrhea; adjusted odds ratios for exposure to gonorrhea and black race were the highest for either infection. CONCLUSIONS: The gonorrhea prevalence rate was very low compared to that of chlamydia in patients at Colorado family planning clinics. Cost-effective gonorrhea testing strategies are needed for this population.

Heterosexual transmission of HIV in China: a systematic review of behavioral studies in the past two decades.

OBJECTIVE: The objective of this study was to address the role of heterosexual transmission of HIV in China. GOAL: The goal of this study was to explore the prevalence of unsafe sex and the likelihood of HIV spread heterosexually from core populations to others. STUDY: The authors conducted a review of behavioral studies. RESULTS: Drug users were more likely to be involved in higher-risk sexual behaviors than were those who abstained from using drugs. Most female drug users (52-98%) reported having engaged in commercial sex. Most female sex workers (FSWs) and individuals with sexually transmitted diseases (STDs) had concurrent sexual partners. Many continued to have unprotected sex after noticing STD symptoms in themselves or their sexual partners. From 5% to 26% of rural-to-urban migrants had multiple sexual partners and 10% of males patronized FSWs during migration. CONCLUSIONS: Factors such as high rates of FSW patronage, low rates of condom use during commercial sex, having sex with both commercial and noncommercial sexual partners, and high rates of STD infection may promote a heterosexual epidemic in China.

Awareness of sexually transmitted disease among women and service providers in rural Bangladesh.

Sexually transmitted disease (STD) in rural Bangladesh is currently a topic of great concern. To date, little information is available in the literature regarding its prevalence. It is now known, however, that the current level of STD awareness among the rural population with regard to modes of transmission and means of prevention is inadequate. In 1994, the MCH-FP Extension Project (Rural) of ICDDR, B surveyed 8674 married women of reproductive age (MWRA) in 4 rural thanas to examine their awareness of STDs. The association between socio-demographic and programmatic factors (variables which affect STD information availability) and awareness of STDs was examined by both bivariate and multivariate analyses. Seven focus group discussions were conducted among groups of government health and family planning workers and paramedics to assess their knowledge of STDs and attitudes about their prevention. Only 12% of the original group had even a basic understanding about STDs and how to protect themselves from them. Twenty-five per cent of the women surveyed had ever heard of either syphilis or gonorrhoea. Of these women, less than half could mention specific mechanisms involved in the transmission of these diseases. Seven per cent reported that syphilis and gonorrhoea are transmitted through sexual intercourse. Thirteen per cent reported that the infections are transmitted from spouses to their partners. Four per cent reported that STDs can be spread by having multiple sexual partners. The results of logistic regression analysis indicate that awareness of STDs was higher among relatively older women than among younger women. Awareness of STDs was most strongly and positively associated with the education of both the women and their husbands. Awareness of STDs was also found to be higher among women who were more socially mobile (e.g. those who frequent cinemas or mothers' clubs). The findings of focus group discussions indicate that family planning and health care service providers have a moderate level of STD awareness. Modes of transmission and means of prevention, however, were areas of weakness. It will, therefore, be necessary, whether to prevent a potential STD epidemic or to combat current STD prevalence, to implement culturally acceptable and affordable means of disseminating knowledge in rural areas of Bangladesh. Training of health care providers will be an essential first step.

Acculturation, sexual behavior, and alcohol use among Latinas.

We explored the relationship of alcohol use to unsafe sex in Latinas. Telephone interviews were conducted with 523 currently sexually active Latinas aged 18-49 years. Only 7.5% of these women used alcohol half of the time or more prior to sex. "Regular" alcohol users had more sexual partners, but also had more experience with condom use, used condoms with primary partners as frequently as nonusers of alcohol, and used condoms more with secondary partners. While Latinas who use alcohol prior to sex more often have multiple sexual partners, alcohol use does not appear to interfere with condom use.

[Characterization of HIV-1 subtypes in Sfax, Tunisia].

UNLABELLED: We studied HIV-1 subtypes in 20 patients, originating from Tunisia in 18 cases and Libya in 2 other cases and seen in Regional Hospital of Sfax during 1993-1997. Among the 18 tunisian patients, 14 are infected by subtype B. Nine of them are living in european countries and were probably infected by intravenous drug and/or sexual route. The five other patients infected by subtype B correspond to autochtonous cases: 3 patients were infected by their partner, 1 was infected by blood transfusion and the last one has had multiple sexual partners. For another tunisian patient, serum cross-reacted with 2 peptides C and B (C/B) corresponding to coinfection or subtype recombination. Two strains were indeterminate by SSEIA. The last tunisian patient, contaminated in Libya, is infected by a strain presenting cross-reactivity with subtype A and C (A/C). This same strain was found in one libyan patient. The second libyan patient is infected by subtype C. CONCLUSION: In Tunisia, we noted the frequency of HIV-1 subtype B, originating from european countries. But, the fear of other HIV-1 subtypes introduction and therefore, the emergency of new recombinants must incite us to a greatest vigilance in survey of HIV-1 infection.

Violence and HIV sexual risk behaviors among female sex partners of male drug users.

OBJECTIVE: Violence and HIV are emerging as interconnected public health hazards among drug users and their families. The purposes of this study are to (1) determine the prevalence of sexual and physical abuse of non-drug-using female sex partners of male drug users, and (2) ascertain the association between such violence and HIV-related risk behaviors. METHODS: From 11/93 to 11/95, 208 female sex partners of injection drug or crack users in Collier County, FL, Tucson, AZ, and Portland, OR, were interviewed as part of a NIDA-funded HIV risk reduction project. Their mean age was 30 years (range 18-54); 21% were White, 6% African American, 7% Native American, and 63% Hispanic. RESULTS: Of the 208 women, 28% reported being sexually molested and 20% raped before age 13; 41% reported being raped at least once in their lifetime. Forty-two percent of the women were physically assaulted by their sex partners; 36% had been threatened with assaulted by their sex partners. Those who were raped or threatened with assault were more likely to have multiple sex partners and engage in unprotected anal sex; there was a trend for women who had been physically assaulted to be more likely to engage in unprotected anal sex. DISCUSSION: Rape, assault and the threat of assault are commonplace in the histories of female sex partners of male drug users. Experiences of violence and threats of violence are associated with heightened risk for the sexual transmission of HIV. Providers of HIV prevention need to understand the sequelae of violence, and design interventions which empower women to protect themselves from sexual transmission of HIV.
