Doxycycline and azithromycin for prevention of chlamydial persistence or recurrence one month after treatment in women. A use-effectiveness study in public health settings.

BACKGROUND: To treat chlamydial infection, the Centers for Disease Control and Prevention recommends either a single dose of azithromycin or a 7-day course of doxycycline. Cost is a concern with the single-dose regimen; compliance is a concern with the multidose regimen. GOAL: To compare the use-effectiveness of azithromycin and doxycycline for preventing persistence or recurrence of Chlamydia trachomatis infection in women and to evaluate associated risk behaviors. STUDY DESIGN: One hundred and ninety-six chlamydia-infected women and their sex partners were recruited into a randomized controlled trial of single-dose versus multidose regimens in seven public health clinics, with no incentives for enrollment, compliance, or follow-up. The outcome, measure was a positive test for C. trachomatis by polymerase chain reaction testing at 1 month after treatment. RESULTS: C. trachomatis positivity at 1 month was similar for women receiving single-dose (5.1%, 5/98) and multidose therapy (4.1%, 4/98). Reported compliance among 73 women taking multidose therapy was 94.5%. A twofold to threefold increased risk of chlamydial persistence or recurrence was observed among women who were < or = 24 and white or who reported: a recent new partner, multiple partners, or a partner who may have had multiple partners at the time of enrollment or that not all partners were treated during the 1-month follow-up period after initiation of treatment. CONCLUSIONS: The use-effectiveness of single-dose and multidose therapy was comparably high. Observed rates of persistence or recurrence were consistent with reported rates of pharmacological treatment failure. However, all women with C. trachomatis detected at 1 month had behavioral risk factors that may have contributed to reinfection.

Sexual behavior risk factors associated with bacterial vaginosis and Chlamydia trachomatis infection.

BACKGROUND AND OBJECTIVES: Few studies have demonstrated that bacterial vaginosis (BV) is associated with sexual behavior risk factors similar to those for other sexually transmitted diseases. The objective of this study was to determine the prevalence of these factors in a multivariate analysis of data from women infected with BV and Chlamydia trachomatis, and noninfected control subjects. GOALS: To study detailed sexual behavior risk factors reported by women with BV versus genital C. trachomatis infection (CT) and by non-BV-infected controls. STUDY DESIGN: A cross-sectional study was conducted with 1,011 women (Swedish Women's Health Study) recruited from family planning and youth clinics in Eskilstuna and Stockholm, Sweden (November, 1989-January, 1991). Participants were evaluated for the presence of BV, CT, Neisseria gonorrhoeae, Treponema pallidum, Trichomonas vaginalis, and human immunodeficiency virus, and interviewed in detail with respect to sexual behaviors. Statistical comparisons were made using chi-square test (Pearson and likelihood ratio), t test, and logistic regression multivariate analysis. RESULTS: Of 956 women eligible for analysis, the prevalence of BV and CT was 13.7% and 8.9%, respectively. The comparison group consisted of the remaining 825 women without BV. After excluding those with concomitant CT infection, there were 118 women with BV who were compared with 72 women with CT infection only. Sexual factors associated with BV versus the comparison group were a short-term relationship before and after sexual debut, high number of lifetime sexual partners, multiple partners during the last month, high orgasm ability, and more frequent history of group sex, sexual abuse, and rape. When the BV group was compared with the CT group, there were no significant differences in sexual activity risk factors, except for a higher frequency of experience of casual sex in the CT group. CONCLUSIONS: Bacterial vaginosis is associated with sexual behavior risk factors similar to those associated with genital CT infection.

Contextual factors and other correlates of sexual risk of HIV among African-American crack-abusing women.

This study examined differences in contextual factors, substance use, sexual risk behaviors, and comorbid histories between African-American, out-of-treatment, crack-abusing women who had either a single sexual partner or multiple partners. Bivariate analysis indicated that women with multiple partners were more likely than women with a single partner to be homeless, financially dependent, and to have histories of sexual, physical, and emotional abuse. Women with multiple partners reported higher levels of depression, anxiety, and more symptoms of posttraumatic stress disorder (PTSD). In multiple logistic regression analysis, being unemployed, difficult childhood, and number of days of crack use in the previous 30 days, longer crack runs, and more frequent unprotected fellatio were associated with increased odds of having multiple sexual partners. Being married or living as married was associated with decreased odds of having multiple sexual partners. The importance of assessing contextual and historical factors and implications for future research is discussed.

Gonorrhea and chlamydia infection among women visiting family planning clinics: racial variation in prevalence and predictors.

CONTEXT: Black women are disproportionately infected with gonorrhea and chlamydia. Because of the potential impact of these infections on women's reproductive health, it is important to determine whether different factors are predictive of infection in women of different races. METHODS: Data from 31,762 women aged 15-24 who were tested for gonorrhea and chlamydia at Missouri family planning clinics in 2001 were used to calculate the prevalence of each infection by selected variables. Logistic regression analysis was used to assess factors associated with the risk of infection. RESULTS: Overall, 0.7% of women had gonorrhea, and 4% had chlamydia. The gonorrhea rate was 4% for blacks and 0.4% for whites; the chlamydia rate, 9% and 4%, respectively. Independent predictors of gonorrhea in both races were symptoms, recent sexual contact with a partner who had STD symptoms, and chlamydia infection. Predictors specific to whites were visiting the clinic for STD care and having a new partner or multiple partners in the past year. Being aged 15-21 was associated with an elevated risk of gonorrhea for blacks only. In both racial groups, chlamydia infection was associated with younger age, contact with a symptomatic partner, cervicitis, cervical friability and gonorrhea positivity. Additional predictors among whites were having a new partner, having multiple partners and having pelvic inflammatory disease; no other factors were significant for blacks. CONCLUSIONS: The prevalence and predictors of gonorrhea and chlamydia infection differ significantly between blacks and whites. Until these disparities are better understood, it will be difficult to establish screening criteria for gonorrhea.

Data from the National AIDS Behavioral Surveys. IV. Multiple sexual partners among young adults in high-risk cities.

Among a sample of 1,334 urban heterosexuals aged 18-25 from the 1990-1991 National AIDS Behavioral Surveys, 24% report having had more than one sexual partner during the past year. Young men are more than twice as likely as young women, and unmarried respondents are eight times as likely as married respondents, to have multiple partners. A multiple regression analysis of the interaction between race or ethnicity and education indicates that among whites, young people with 12 or more years of education are four times as likely to have multiple partners as are those with less than a high school education; among Hispanics and blacks, educational level is not related to having more than one partner. Among those with multiple partners, approximately 40% never use condoms with primary or secondary partners, and condom use decreases with increasing number of partners.

Multiple sexual partners and their psychosocial correlates: the population-based AIDS in multiethnic neighborhoods (AMEN) study.

In this study we examined multiple partners in a household probability sample of heterosexuals. Thirty-seven percent reported 2 or more partners in the past year, and 6% reported 5 or more partners. Significant interactions among gender, ethnicity, and relationship status revealed complex relations. African American men without a primary partner were the most likely to have multiple partners; ethnic minority women with primary partners were the least likely. Psychosocial factors associated with multiple partners were examined with the AIDS Risk Reduction Model (ARRM). Situational factors influenced how ARRM variables related to multiple partners. Perceived risk, commitment to monogamy, and communication were all important correlates. Prevention efforts must focus on increasing awareness of the risks of heterosexual transmission of HIV for people in dating relationships and on strengthening sexual communication skills with new partners.

Multiple heterosexual partners and condom use among Hispanics and non-Hispanic whites.

A telephone survey of 1,592 Hispanic and 629 non-Hispanic white men and women aged 18-49, randomly selected from nine states in the northeastern and southwestern United States, found that married Hispanic men are more likely to have had two or more heterosexual partners in the previous 12 months than are married non-Hispanic men (18% and 9%, respectively). A large proportion of unmarried men (60% of Hispanics and 54% of non-Hispanic whites) report having had more than one partner in the past 12 months. After adjusting for other variables, the odds of having multiple partners are 2.5 times higher among Hispanic men aged 18-24 than among those aged 41-49 and 1.8 times higher among those who live in the Northeast than among those in the Southwest. Highly acculturated Hispanic men are less likely to have multiple partners than are less acculturated men. Among Hispanic women, those who are moderately or highly acculturated are more likely to have multiple partners (odds ratios of 4.9 and 8.4, respectively) than are less acculturated women. About half of men and women with multiple partners report always using condoms with secondary heterosexual partners.

Multiple sexual partners among U.S. adolescents and young adults.

CONTEXT: Because many teenagers and young adults fail to use condoms correctly and consistently, the number of sexual partners they have is an important risk factor for sexually transmitted diseases, including HIV. Identifying factors that are associated with having multiple partners can help in the design of disease interventions. METHODS: Data on 8,450 males and females aged 14-22 who participated in the 1992 Youth Risk Behavior Survey were used to examine the prevalence of and factors associated with young people's having multiple partners. RESULTS: In all, 63% of female respondents and 64% of males were sexually experienced. Among those who had had sex during the three months before the survey, 15% and 35%, respectively, had had two or more partners during that period. At each age, the majority of sexually experienced respondents had had more than one lifetime partner; between ages 14 and 21, the proportion who had had six or more rose from 8% to 31% among females and from 14% to 45% among males. In logistic regression analyses, alcohol use, illicit drug use and young age at first coitus were associated with increased odds that females had had two or more partners in the previous three months, and being married lowered the odds; black or Hispanic race or ethnicity, alcohol use and young age at first coitus increased the odds for males, and being married reduced the odds. As the number of reported alcohol-related behaviors increased, the adjusted proportion of respondents who had recently had multiple partners rose from 8% to 48% among females and from 23% to 61% among men. CONCLUSIONS: The strong association between alcohol use and having multiple sexual partners underscores the need to educate young people about the effects of alcohol on partner choice and the risk of infection with sexually transmitted diseases.

The risk of HIV infection in a national sample of women with injection drug-using partners.

OBJECTIVES: This study reports on a large, national cohort of women with injection drug-using sex partners. Information is provided on demographic characteristics; human immunodeficiency virus (HIV) risk factors, including unprotected sex and incidence of sexually transmitted diseases; use of noninjected drugs; HIV serostatus; and other selected health variables. METHODS: A sample of 5162 heterosexual women was recruited for a national acquired immunodeficiency syndrome (AIDS) research and demonstration project. A structured interview was administered, and the women had the option of undergoing HIV testing. Statistical analyses compared three groups on variables of interest: women with single sex partners, women with multiple partners, and women with multiple partners who exchanged sex for drugs and/or money. RESULTS: These groups differed significantly on virtually all of the demographic and risk variables examined. Women with multiple partners who exchanged sex for drugs and/or money were at higher risk for HIV than women in the other groups, even when selected demographic variables were controlled. CONCLUSIONS: Research is needed on the efficacy of prevention efforts involving these diverse groups of women at risk for AIDS.

Exposure to violence and associated health-risk behaviors among adolescent girls.

OBJECTIVE: To examine the relationship between exposure to violence and health-risk behaviors. DESIGN: Cross-sectional survey. SETTING: University-based outpatient family planning clinic. PATIENTS: Sexually active adolescent girls younger than 18 years (N = 517) who presented for contraceptive care. MAIN OUTCOME MEASURES: Prevalence of witnessing or experiencing violence and the associations with health-risk behaviors, including high-risk sexual behaviors, substance use, and self-injury. RESULTS: Compared with adolescents who had not been exposed to violence, those who had only witnessed violence were 2 to 3 times more likely to report using tobacco and marijuana, drinking alcohol or using drugs before sex, and having intercourse with a partner who had multiple partners. Those who had experienced, but not witnessed violence were at increased risk of these same behaviors and were 2 to 4 times more likely than those who had neither witnessed nor experienced violence to report early initiation of intercourse, intercourse with strangers, multiple partners, or partners with multiple partners, tobacco, alcohol and drug use, or to have positive test results for a sexually transmitted disease. Individuals who had both witnessed and experienced violence demonstrated the greatest risk of adverse health behaviors. These adolescents demonstrated 3 to 6 times greater risk of suicidal ideation (odds ratio [OR], 3.1; 95% confidence interval [CI], 2.2-4.0) or suicide attempts (OR, 4.5; 95% CI, 2.2-9.4), self-injury (OR, 5.8; 95% CI, 2.6-12.9), and use of drugs before intercourse (OR, 6.2; 95% CI, 3.0-12.9) than those who had neither witnessed nor experienced violence. CONCLUSIONS: Adolescents exposed to violence are at increased risk of multiple adverse health behaviors. Programs designed to improve health outcomes should target this high-risk group.

Data from the National AIDS Behavioral Surveys. II. Multiple sexual partners among Hispanics in high-risk cities.

Data from a random sample of 4,658 heterosexual Hispanics from 23 high-risk cities in the 1990-1991 National AIDS Behavioral Surveys reveal that 11% of Hispanics have had multiple partners in the past year-17% of men and 4% of women. The study shows a higher proportion of multiple sexual partners in the past year among Hispanic men who are unmarried (31%), Cuban (28%), aged 18-29 (25%), better educated (21%), of lower income (23%) and highly acculturated (20%). Among Hispanic women, marital status, age, Hispanic subgroup and level of acculturation are significant predictors of having multiple partners. Among highly acculturated Hispanic men, income, Hispanic subgroup and marital status are significant predictors of having multiple partners; among less acculturated Hispanic men, marital status is the only significant predictor. Only 20% of Hispanics with multiple partners report using a condom regularly with their primary partner, and 29% report regular condom use with their secondary partner. Among men, condom use tends to decrease as the number of partners increases.

Cancer of the cervix--a sexually transmitted disease. Cytologic screening in a prostitute population.

The epidemiology of cervical cancer has been the subject of many articles centered around the question, "Is cancer of the cervix a sexually transmitted disease? A group of 750 Taiwan prostitutes had cervical cytology performed at the time of required gonorrhea screening. The prostitutes represented a unique group in which the variables of frequent intercourse with multiple partners and multiple infection can be separated from early coital experience. Cervical cytology was obtained and processed by the Pathology Department at Navy Medical Research Unit No. 2. A bilingual questionnaire was completed with the aid of a medical interpreter. The results included only eight of the 750 specimens in the "dysplasia plus" category for a rate of 10.7 per 1,000. The low yield of abnormal cytology suggests the factors of multiple partners, frequent intercourse, and high gonorrhea infection rate are not significant epidemiologically if they occur after the phase of active metaplasia, occurring during the first pregnancy or early adolescence.

Regional distribution and incidence of human papillomavirus infections among heterosexual men and women with multiple sexual partners: a prospective study.

OBJECTIVE: To assess prevalence, incidence and potential risk factors of human papillomavirus (HPV) infection among heterosexual men and women with multiple partners and to identify niches of HPV-infection. DESIGN: A prospective study of heterosexual men and women with multiple partners attending an STD clinic as participants in a study on HIV from May 1988 until January 1991. Routine STD examination and physical examination using colposcopy were performed, interviews with standardised questionnaires were administered. Specimens for HPV DNA detection by polymerase chain reaction were collected from multiple sites of the genital, anorectal and oral regions. In women cervical cytology was performed. SETTING: The STD Clinic of the Municipal Health Service of Amsterdam. PARTICIPANTS: 162 women and 85 men entered the study, 110 women and 48 men were followed up. RESULTS: At entry of the study 37 (23%) women and 24 (28%) men were found positive for HPV DNA at any site. Only in one woman was oral presence of HPV DNA found during follow-up. Abnormal cervical cytology was observed in four women. In multivariate analysis, diagnosis of condylomata [odds ratio (OR) 5.61, 95% confidence interval (CI) 1.86 to 16.90)], reporting genital dermatological abnormalities (OR 3.72, 95% CI 1.38 to 9.99) and age (OR per year 0.93, 95% CI 0.88 to 0.99) predicted independently the presence of HPV DNA in women at entry of the study. In women 59 of the 99 (60%) HPV infections were observed in the genital region and 40% in the anorectal region: in men these figures were 65% and 35%, respectively. The incidence of HPV infection was 47.1 and 50.5 per 100 person-years for women and men respectively. At least 20/99 (20%) infections in women were intermediate or long persistent and only 3/48 (6%) HPV infections in men (P = 0.03). No risk factor for persistency could be determined, either in women or in men. CONCLUSIONS: HPV infection was found to be a multicentric genital and/or anorectal event both in women and men. The oral presence of HPV DNA was detected only once in one of the participants. In women persistent HPV infection was more common than in men. Independent predictors for presence of HPV DNA in women were diagnosis of condylomata acuminata, reporting genital dermatologic abnormalities and age. Incidence of HPV infection in women turned out to be 47.1 infections per 100 person-years and for men 50.5 per 100 person-years.

Review of evidence from risk factor analyses associating HIV infection in African adults with medical injections and multiple sexual partners.

Studies of risk factors for human immunodeficiency virus (HIV) infections in sub-Saharan Africa present a wealth of evidence relevant to ongoing debates about the contributions of unsterile health care and sexual transmission to Africa's HIV epidemics. From studies which meet search criteria (n = 39) we calculate population attributable fractions (PAFs) for incident and prevalent HIV infections associated with exposure to medical injections and with having more than one sexual partner. Median and mean crude PAFs for injections for both incident and prevalent HIV exceed those for multiple partners. Evidence suggests that adjustments for reverse causation (people with HIV-related symptoms seeking injections) and confounding do not explain away the large PAFs for injections. Misreporting of sexual behaviour has an unknown impact on PAFs for multiple partners. However, most PAFs for incident HIV infections are from communities with low-growth epidemics; hence data about the most important risk factors fuelling high-growth epidemics are sparse. Empirical resolution of ongoing debates may be possible with the aid of future research-especially in high-growth epidemic settings-that investigates risks for HIV transmission through a full range of sexual and parenteral exposures with attention to reverse causation, confound, and quality of sexual behaviour data.

Male heterosexual crack smokers with multiple sex partners: between- and within-person predictors of condom use intention.

Little research has examined predictors of condom intention within concurrent partnerships. This study examined predictors of intention among 259 male African-American crack smokers with multiple partners. Each participant reported personal condom intention at next sex, condom use self-efficacy, responsibility and outcome expectances for himself and his perceptions for his last two sex partners. Stepwise logistic regressions showed that for both partners one and two, condom use at last sex and personal responsibility for condom use were predictors of intention to use condoms at next sex. Perceived partner responsibility was an additional positive predictor with Partner 2. Hierarchical generalized linear model analyses showed that positive intention was associated negatively with perceived partner responsibility and intimacy, while positively related to situational self-efficacy. Personal responsibility interacted with intimacy such that only men who indicated the highest levels of intimacy were more likely to intend to use condoms. Overall, the findings in this study support the need for examining additional social cognitive constructs that capture the interpersonal aspects of sexual relationships such as personal and perceived responsibility, intimacy and how beliefs may change between multiple partners and across time. Finally, the differences in the valence of perceived partner responsibility across analyses and the interaction of personal responsibility with intimacy suggest the need for studies that include measure of power within the relationship.

Determinants of multiple sexual partners and condom use among sexually active Tanzanians.

This paper is based on the analyses of data collected in the Tanzania Demographic and Health Survey (TDHS). The TDHS national sample was obtained by using 1988 population census list of enumeration areas. Information about sexual behaviour and condom use was obtained from sexually active women (N = 4620) and men (N = 1440) reporting sexual activity during the period of four weeks preceding the survey. Univariate and multivariate (using logistic regression model) analyses were done to identify predictors of condom use and highrisk sexual behaviour. About 6% of women and 31% of men reported to have more than one sexual partner during the study period. Compared to respondents married once and in monogamous union, the tendency to have multiple partners was increased among never married women [OR 10.9, 95% CI (7.1-16.9)] and men [2.6 (1 7-3.9)], formerly married women [11.5 (7.3-17.9)], and among men in monogamous marriage reporting more than one marriage [12.4 (8.3-18.4)]. Occupation, residence, ever use of contraceptives, and AIDS knowledge were not associated with history of multiple sexual partners. Only 134 (9.3%) men and 173 (3.7%) women reported to have used condoms during the study period. After adjusting for other predictors of condom use, respondents reporting multiple sexual partners were more likely to have used condom among both women [3.4 (2.2-5.4)] and men [3.3 (2.3-6.0)]. Condom use was common in urban areas than rural areas and among unmarried respondents. These results show that high-risk sexual behaviour is common among men. Condom use was very low indicating that efforts to promote condom use has been less successful in Tanzania. More efforts are needed to promote safer sexual practices and condom use in Tanzania.

Multiple sclerosis: will it come between us? Sexual concerns of clients and their partners.

Multiple sclerosis (MS), an unpredictable neurologic disease, is sometimes called the crippler of young adults. This crippling effect often involves sexual functioning. Sexuality is an issue that is frequently difficult for clients, their partners and health care providers to discuss. To address this difficulty, a teaching pamphlet entitled, MS ... Will it Come Between Us? was produced. Open communication and creativity are helpful in dealing with problems frequently encountered by clients with MS: fatigue, impotence, decreased vaginal lubrication, bladder and bowel dysfunction. The pamphlet helps clients with these issues as well as the basics of sexuality as a whole.

Multiple sexual partners and mother-to-child transmission of HIV-1.

OBJECTIVE: To investigate risk factors for mother-to-child transmission of HIV-1, particularly sexual behavior before and during pregnancy. DESIGN AND METHODS: This study is part of a prospective cohort study in Butare, Rwanda, of 318 HIV-1-seropositive and 309 HIV-1-seronegative women enrolled during pregnancy and followed for a mean duration of 21 months (range, 8-34 months). Clinical follow-up of the mother-infant pairs was performed at 6-week intervals during the first year of life and at 4-month intervals thereafter. Detailed sexual history interviews were conducted during pregnancy and at the first postnatal visit. RESULTS: Of 184 singleton infants born to HIV-1-infected mothers who survived the neonatal period, 32 (17%) children were classified as HIV-1-infected, 130 (71%) as not infected, and 22 (12%) died with indeterminate HIV-1 infection status. The vertical transmission rate was estimated to be between 20 and 29%. Unprotected sexual intercourse with increased number of partners during the past 5 years was strongly associated with mother-to-child transmission (P < 0.001), even after adjustment for maternal CD4/CD8 ratio, parity, history of sexually transmitted diseases, and evidence of genital infection during pregnancy. In a multivariate analysis, excluding children with indeterminate HIV-1 status, odds ratios for vertical transmission were 2.6 [95% confidence interval (CI), 1.0-6.9] for maternal CD4/CD8 ratio < 0.5 and 3.6 (95% CI, 1.1-11.8) for more than three sexual partners versus a single partner. Women with more than one sexual partner during the first trimester of pregnancy were at particularly high risk of transmitting the virus. CONCLUSION: Unprotected sexual intercourse with multiple partners before and during pregnancy in a population with high HIV-1 seroprevalence may well increase the likelihood of HIV-1 transmission from an infected mother to her child.
