Pregnant adolescents at risk: sexual behaviors and sexually transmitted disease prevalence

Expedited Partner Therapy: A Multicomponent Initiative to Boost Provider Counseling

BACKGROUND

Expedited partner therapy prescription remains low and highly variable throughout the United States, leading to frequent reinfections with Chlamydia trachomatis and Neisseria gonorrhoeae . We examined provider counseling on expedited partner therapy before and after an electronic smart tool-based initiative.

METHODS

In this quasi-experimental interrupted time-series study, we implemented an initiative of electronic smart tools and education for expedited partner therapy in March 2020. We reviewed the records of patients with chlamydia and/or gonorrhea at an urban, academic obstetrics and gynecology clinic in the preimplementation (March 2019-February 2020) and postimplementation (March 2020-February 2021) groups. Descriptive statistics and an interrupted time-series model were used to compare the percent of expedited partner therapy offered by clinicians to patients in each group.

RESULTS

A total of 287 patient encounters were analyzed, 155 preintervention and 132 postintervention. An increase in expedited partner therapy counseling of 13% (95% confidence interval [CI], 2%-24%) was observed before the intervention (27.1% [42 of 155]) versus after the intervention (40.2% [53 of 132]). Significant increases in provider counseling were seen for patients who were single (15%; 95% CI, 3%-26%), 25 years or older (21%; 95% CI, 6%-37%), receiving public insurance (15%; 95% CI, 3%-27%), seen by a registered nurse (18%; 95% CI, 4%-32%), or seen for an obstetrics indication (21%; 95% CI, 4%-39%). No difference was seen in patients' acceptance of expedited partner therapy ( P = 1.00).

CONCLUSIONS

A multicomponent initiative focused on electronic smart tools is effective at increasing provider counseling on expedited partner therapy. Further research to understand patient perceptions and acceptance of expedited partner therapy is critical.

High incidence of asymptomatic genital tract infections in pregnancy in adolescent girls and young women: need for repeat aetiological screening

INTRODUCTION

Sexually transmitted infection (STI) prevalence and incidence estimates for pregnant adolescents are under-reported. We estimated prevalence and incidence of STIs in pregnant adolescents (15-19 years) in comparison with pregnant women 20-24 and >25 years.

METHODS

Pregnant women registering at primary care clinics in Umlazi, a periurban subdistrict in KwaZulu-Natal, South Africa, were enrolled in an HIV incidence cohort study during February 2017-March 2018. Women were examined for abnormal vaginal discharge, received empirical treatment, tested for HIV-1 and had vaginal swabs taken at their first and a subsequent visit in the third trimester. Vaginal swabs were stored for STI testing at completion of study and tested for Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhoeae and Mycoplasma genitalium using PCR.

RESULTS

A total of 752 HIV-negative pregnant women were enrolled at a median gestational age of 17 weeks: 180 (23.9%), 291 (38.7%) and 281 (37.4%) in the 15-19, 20-24 and >25 years age groups. Pregnant adolescents had an STI prevalence of 26.7% at baseline, not significantly lower than the 20-24 (34.7%, OR 1.4; 95% CI 1.0 to 2.1, p=0.09) and >25 years (33.8%, OR 1.4; 95% CI 0.9 to 2.1, p=0.12) age groups. T. vaginalis (11.1%), C. trachomatis (7.8%) and N. gonorrhoeae (4.4%) were most prevalent in adolescents, a trend similar to the other age groups. Overall, 43.4% were symptomatic and treated at baseline. Overall, 40.7% (118 of 290) of women who tested negative for an STI at baseline tested positive at the repeat visit (incidence 19.5/100 person years). STI incidence in pregnant adolescents was 23.9/100 person years and comparable with older age groups (20.5/100 person years and 16.2/100 person years). At the repeat visit, 19.0% of all women with an STI were symptomatic and treated. Performance of syndromic management was poor at baseline (negative predictive value (NPV) 68.6%, positive predictive value (PPV) 34.0%) and at repeat visit (NPV 58.4%, PPV 34.3%).

CONCLUSIONS

Prevalence of asymptomatic curable STIs in pregnant adolescents is high and comparable with women >20 years old. Adolescents remain at substantial risk of asymptomatic incident STIs during pregnancy.

Development of multiplex real-time quantitative PCR for simultaneous detection of Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, and Mycoplasma genitalium in infertile women

PURPOSE

Sexually Transmitted Diseases (STDs) can cause sterility and many other problems for women planning pregnancy. Currently, almost 340 million people worldwide suffer from Sexually Transmitted Infections (STIs). This study made attempts to quickly identify STDs' most critical infectious agents using dedicated primers and probes.

METHODS

The present study was done on the cervical samples of 200 infertile women. After extracting the total DNA of Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, and Mycoplasma genitalium, quantitative methods were employed to determine the rate of target bacteria using multiplex real-time PCR.

RESULTS

The multiplex qPCR showed the rates of 47%, 16%, 46%, and 16.5% for Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, and Mycoplasma genitalium in infertile women, respectively. In some patients, there were co-infections with two or three bacteria. The diagnostic approach used in our research could be employed as an alternative detection tool to identify the four most common STD-associated bacterial agents while detecting mixed infections.

CONCLUSIONS

Infertile women with no biological problems could have their genital tract checked using this newly designed identification technique and get proper treatment for their infections as quickly as possible.

Health Behaviors and Prenatal Health Conditions in Repeat Vs First-time Teenage Mothers in the United States: 2015-2018

STUDY OBJECTIVE

Repeat teenage mothers, those who give birth to a second or higher-order infant before age 20 years, are at elevated risk for adverse perinatal outcomes compared with first-time teenage mothers. The objective of the current study was to compare the prevalence of negative pregnancy-related behaviors and gestational health conditions in the national United States population of first-time and repeat teenage mothers.

DESIGN, SETTING, AND PARTICIPANTS

We conducted a retrospective, population-based cohort study using annual US birth data files from 2015 to 2018, N = 799,756 (673,394 [84.2%] first, 126,362 [15.8%] repeat) births to women ages 15-19 years.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Pregnancy-related behaviors (including adequacy of prenatal care and weight gain, sexually transmitted infection, smoking, and breastfeeding) and gestational health conditions (gestational hypertension and gestational diabetes).

RESULTS

Repeat (vs first-time) mothers had higher prevalence of negative pregnancy-related behaviors: inadequate prenatal care, smoking, inadequate weight gain, and sexually transmitted infection during pregnancy; they were also less likely to breastfeed. Conversely, repeat teenage mothers experienced lower prevalence of gestational hypertension and gestational diabetes.

CONCLUSION

Repeat teenage mothers experienced lower prevalence of physical health complications during pregnancy but engaged in more negative pregnancy-related health behaviors. Negative health behavior in pregnancy can lead directly to poor perinatal outcomes for infants. To prevent adverse outcomes from repeat teenage childbearing, we must ensure access to quality, timely, prenatal and postpartum care so teenage mothers can receive support for healthy pregnancy-related behaviors as well as linkage to highly effective contraception to prevent unintended repeat births.

Prevalence of Chlamydia and Gonorrhea Among Pregnant Adolescents Screened in the Third Trimester Using a Urine PCR Test: A Retrospective Review

OBJECTIVE

Our study assessed the rate of new and recurrent Chlamydia trachomatis and Neisseria gonorrhoeae infections in the third trimester at an adolescent obstetrics clinic.

METHOD

Between October 2016 and June 2020, routine third-trimester screening for C. trachomatis and N. gonorrhoeae was implemented according to new Canadian recommendations. Urine nucleic acid amplification was performed. Patient records were reviewed retrospectively, and demographic data; pregnancy and delivery characteristics; and information on screening at presentation to care, third-trimester screening (33-38 weeks), and other STI testing was recorded.

RESULTS

A total of 115 adolescents (mean age 17.90 ± 1.43 y) with 125 pregnancies presented for care. Twenty-three pregnancies were excluded (12 transferred out and 11 experienced a pregnancy loss). At presentation, screening was performed in 100 of 102 pregnancies: 64 of 100 at <13 weeks, 32 of 100 at 13-27 weeks, and 4 of 100 at 28-30 weeks. Nine tested positive for C. trachomatis and none tested positive for N. gonorrhoeae. In the third trimester, there were 3 positive C. trachomatis tests, but all were indicated: test of cure was due for 1 patient, 1 patient had a new sexual partner, and 1 patient presented with symptoms. The remaining 89 of 102 pregnancies were screened (with no other indication) and none were positive for C. trachomatis or N. gonorrhoeae. Ten patients could not be sampled (5 missed, 4 pre-term deliveries, and 1 non-compliant with testing).

CONCLUSION

No cases of C. trachomatis or N. gonorrhoeae infection were identified on third-trimester screening in our study. Adolescent obstetrics providers implementing Canadian screening guidelines may want to monitor their screening results to determine whether their yield warrants universal implementation.

Influence of Sexually Transmitted Infections in Pregnant Adolescents on Preterm Birth and Chorioamnionitis

Background

Adolescents have an increased risk of preterm birth (PTB) and sexually transmitted infections (STIs). We examined the prevalence and impact of STIs (gonorrhea, chlamydia, and trichomonas) on PTB and chorioamnionitis in pregnant adolescents.

Methods

This retrospective cohort study utilized the first pregnancy delivered at an urban hospital among patients ≤ 19 years old over a 5-year period. Poisson regression with robust standard errors was used to estimate prevalence ratios (PR) and 95% confidence intervals (CI) of the association between STIs and PTB (<37 weeks) and chorioamnionitis identified by clinical or placental pathology criteria.

Results

739 deliveries were included. 18.8% (n = 139) of births were preterm. The overall prevalence of STIs during pregnancy was 16.5% (Chlamydia trachomatis: 13.1%, n = 97; Trichomonas vaginalis: 3.7%, n = 27; and Neisseria gonorrheae: 3.1%, n = 23). Detection of C. trachomatis, T. vaginalis, or N. gonorrheae was not associated with increased PTB. While infection with N. gonorrheae and C. trachomatis did not increase the likelihood of any chorioamnionitis, infection with T. vaginalis significantly increased the likelihood of any chorioamnionitis diagnosis (aPR 2.19, 95% CI 1.26-3.83).

Conclusion

In this adolescent population with a high rate of PTB, in whom most received appropriate STI treatment, we did not find an association between STI during pregnancy and an increased rate of PTB. However, an infection with T. vaginalis was associated with an increased likelihood of chorioamnionitis. Early detection of STIs may prevent adverse pregnancy outcomes. Continued vigilance in STI screening during pregnancy, including consideration of universal Trichomonas vaginalis screening, is merited in this high-risk population.

Adolescent Sexual Health: Identity, Risk, and Screening for Sexually Transmitted Infections

Development of SOGIE (sexual orientation and gender identity and expression) is not unique to minority populations, as all adolescents grapple with their sexuality and identity. Health care providers straddle the unique positions of authority figure and advocate and can help these young people establish behaviors that will allow them to flourish as adults. This article discusses the appropriate language to use while conducting a sexual history, summarizes the epidemiologic data on sexually transmitted infections, and reviews the screening and reporting guidelines set forth by the United States Preventive Services Task Force and the Centers for Disease Control and Prevention.

A Missed Opportunity for U.S. Perinatal Human Immunodeficiency Virus Elimination: Pre-exposure Prophylaxis During Pregnancy

OBJECTIVE

To estimate the proportion of women at increased risk of sexual human immunodeficiency virus (HIV) acquisition during pregnancy in a high HIV incidence urban setting to identify those who may be eligible for pre-exposure prophylaxis.

METHODS

We conducted a retrospective cohort study of women who received prenatal care at a large academic center in 2012. Univariable analyses and multiple logistic regression models were built to identify correlates for pre-exposure prophylaxis eligibility.

RESULTS

Among 1,637 pregnant women, mean age was 27.6 years (SD 6.3), 59.7% were African American, and 56.0% were single. Based on the Centers for Disease Control and Prevention's guidelines, more than 10% of women were at increased risk for HIV acquisition during pregnancy and eligible for pre-exposure prophylaxis. Younger [adjusted odds ratio (OR) 0.9/1-year increase, 95% CI 0.8-0.9], single (adjusted OR 2.4, 95% CI 1.2-4.8), African American women (adjusted OR 3.3, 95% CI 1.6-6.7) with higher parity (adjusted OR 1.3/one-child increase, 95% CI 1.1-1.5), and who smoked regularly during pregnancy (adjusted OR 1.8, 95% CI 1.0-3.0) had greater odds of being eligible for pre-exposure prophylaxis at any time during pregnancy.

CONCLUSIONS

Pregnancy is a vulnerable period during which some heterosexual women in urban settings have a high risk for HIV acquisition and stand to benefit from pre-exposure prophylaxis.

Adolescent Pregnancy

Adolescent pregnancy, although on the decline, represents a significant public health concern. Often adolescents present late to prenatal care, either from lack of knowledge, fear of consequences, limited access, stigma, or all of the above. Although multifaceted, there are many risks both to mother and child that are increased in adolescent pregnancy. Many are unintended and are at risk for repeat adolescent pregnancy, especially within the first 2 years. Risks include but are not limited to: low birth weight, preterm delivery, stillbirth, and preeclampsia, as well as feelings of social isolation, delayed or neglected educational goals, and maternal depression.

Masculine Ideology, Sexual Communication, and Sexual Self-Efficacy Among Parenting Adolescent Couples

This study examined the relationship between traditional masculine role norms (status, toughness, anti-femininity) and psychosocial mechanisms of sexual risk (sexual communication, sexual self-efficacy) among young, low-income, and minority parenting couples. Between 2007 and 2011, 296 pregnant adolescent females and their male partners were recruited from urban obstetrics clinics in Connecticut. Data regarding participants' beliefs in masculine role norms, frequency of general sex communication and sexual risk communication, and sexual self-efficacy were collected via computer-assisted self-interviews. Generalized estimating equation (GEE) models were used to test for actor effects (whether a person's masculine role norms at baseline influence the person's own psychosocial variables at 6-month follow-up) and partner effects (whether a partner's masculine role norms at baseline influence an actor's psychosocial variables at 6-month follow-up). Results revealed that higher actor status norms were significantly associated with more sexual self-efficacy, higher actor toughness norms were associated with less sexual self-efficacy, and higher actor anti-femininity norms were significantly associated with less general sex communication, sexual risk communication, and sexual self-efficacy. No partner effects were found. These results indicate a need for redefining masculine role norms through family centered approaches in pregnant or parenting adolescent couples to increase sexual communication and sexual self-efficacy. Further research is needed to understand partner effects in the context of a relationship and on subsequent sexual risk behavior.

Depression, Abuse, Relationship Power and Condom Use by Pregnant and Postpartum Women with Substance Abuse History

Substance-abusing pregnant and postpartum women are less likely to maintain consistent condom use and drug and alcohol abstinence, which is particularly concerning in high HIV-prevalence areas. Data from 224 pregnant and postpartum women in substance abuse treatment were analyzed to examine effects of history of substance use, child abuse, and mental health problems on current substance use and condom-use barriers. Mediators were depression, relationship power and social support. Most participants (72.9 %) evidenced current depression. Less social support (-0.17, p < 0.05) and relationship power (-0.48, p < 0.001), and greater depression (-0.16, p < 0.05) predicted more condom-use barriers. History of mental health problems predicted condom-use barriers, mediated by recent depression and relationship power (0.15, p < 0.001). These findings suggest depression and diminished relationship power limit highest-risk women's ability to negotiate condom use and abstain from substance use, increasing their risk of acute HIV infection and vertical transmission.

Adolescent Pregnancy Guidelines

OBJECTIVE

To describe the needs and evidence-based practice specific to care of the pregnant adolescent in Canada, including special populations.

OUTCOMES

Healthy pregnancies for adolescent women in Canada, with culturally sensitive and age-appropriate care to ensure the best possible outcomes for these young women and their infants and young families, and to reduce repeat pregnancy rates.

EVIDENCE

Published literature was retrieved through searches of PubMed and The Cochrane Library on May 23, 2012 using appropriate controlled vocabulary (e.g., Pregnancy in Adolescence) and key words (e.g., pregnancy, teen, youth). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Results were limited to English or French language materials published in or after 1990. Searches were updated on a regular basis and incorporated in the guideline to July 6, 2013. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, national and international medical specialty societies, and clinical practice guideline collections.

VALUES

The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). BENEFITS/HARMS/COSTS: These guidelines are designed to help practitioners caring for adolescent women during pregnancy in Canada and allow them to take the best care of these young women in a manner appropriate for their age, cultural backgrounds, and risk profiles.

RECOMMENDATIONS

1. Health care providers should adapt their prenatal care for adolescents and offer multidisciplinary care that is easily accessible to the adolescent early in the pregnancy, recognizing that adolescents often present to care later than their adult counterparts. A model that provides an opportunity to address all of these needs at one site may be the preferred model of care for pregnant adolescents. (II-1A) 2. Health care providers should be sensitive to the unique developmental needs of adolescents through all stages of pregnancy and during intrapartum and postpartum care. (III-B) 3. Adolescents have high-risk pregnancies and should be managed accordingly within programs that have the capacity to manage their care. The unique physical risks of adolescent pregnancy should be recognized and the care provided must address these. (II-1A) 4. Fathers and partners should be included as much as possible in pregnancy care and prenatal/infant care education. (III-B) 5. A first-trimester ultrasound is recommended not only for the usual reasons for properly dating the pregnancy, but also for assessing the increased risks of preterm birth. (I-A) 6. Counselling about all available pregnancy outcome options (abortion, adoption, and parenting) should be provided to any adolescent with a confirmed intrauterine gestation. (III-A) 7. Testing for sexually transmitted infections (STI) (II-2A) and bacterial vaginosis (III-B) should be performed routinely upon presentation for pregnancy care and again in the third trimester; STI testing should also be performed postpartum and when needed symptomatically. a. Because pregnant adolescents are inherently at increased risk for preterm labour, preterm birth, and preterm pre-labour rupture of membranes, screening and management of bacterial vaginosis is recommended. (III-B) b. After treatment for a positive test, a test of cure is needed 3 to 4 weeks after completion of treatment. Refer partner for screening and treatment. Take the opportunity to discuss condom use. (III-A) 8. Routine and repeated screening for alcohol use, substance abuse, and violence in pregnancy is recommended because of their increased rates in this population. (II-2A) 9. Routine and repeated screening for and treatment of mood disorders in pregnancy is recommended because of their increased rates in this population. The Edinburgh Postnatal Depression Scale administered in each trimester and postpartum, and more frequently if deemed necessary, is one option for such screening. (II-2A) 10. Pregnant adolescents should have a nutritional assessment, vitamins and food supplementation if needed, and access to a strategy to reduce anemia and low birth weight and to optimize weight gain in pregnancy. (II-2A) 11. Conflicting evidence supports and refutes differences in gestational hypertension in the adolescent population; therefore, the care usual for adult populations is supported for pregnant adolescents at this time. (II-2A) 12. Practitioners should consult gestational diabetes mellitus (GDM) guidelines. In theory, testing all patients is appropriate, although rates of GDM are generally lower in adolescent populations. Practitioners should be aware, however, that certain ethnic groups including Aboriginal populations are at high risk of GDM. (II-2A) 13. An ultrasound anatomical assessment at 16 to 20 weeks is recommended because of increased rates of congenital anomalies in this population. (II-2A) 14. As in other populations at risk of intrauterine growth restriction (IUGR) and low birth weight, an ultrasound to assess fetal well-being and estimated fetal weight at 32 to 34 weeks gestational age is suggested to screen for IUGR. (III-A) 15. Visits in the second or third trimester should be more frequent to address the increased risk of preterm labour and preterm birth and to assess fetal well-being. All caregivers should be aware of the signs and symptoms of preterm labour and should educate their patients to recognize them. (III-A) 16. It should be recognized that adolescents have improved vaginal delivery rates and a concomitantly lower Caesarean section rate than their adult counterparts. (II-2A) As with antenatal care, peripartum care in hospital should be multidisciplinary, involving social care, support for breastfeeding and lactation, and the involvement of children's aid services when warranted. (III-B) 17. Postpartum care should include a focus on contraceptive methods, especially long-acting reversible contraception methods, as a means to decrease the high rates of repeat pregnancy in this population; discussion of contraception should begin before delivery. (III-A) 18. Breastfeeding should be recommended and sufficient support given to this population at high risk for discontinuation. (II-2A) 19. Postpartum care programs should be available to support adolescent parents and their children, to improve the mothers' knowledge of parenting, to increase breastfeeding rates, to screen for and manage postpartum depression, to increase birth intervals, and to decrease repeated unintended pregnancy rates. (III-B) 20. Adolescent women in rural, remote, northern, and Aboriginal communities should be supported to give birth as close to home as possible. (II-2A) 21. Adolescent pregnant women who need to be evacuated from a remote community should be able to have a family member or other person accompany them to provide support and encouragement. (II-2A) 22. Culturally safe prenatal care including emotional, educational, and clinical support to assist adolescent parents in leading healthier lives should be available, especially in northern and Aboriginal communities. (II-3A) 23. Cultural beliefs around miscarriage and pregnancy issues, and special considerations in the handling of fetal remains, placental tissue, and the umbilical cord, must be respected. (III).

Looking for solutions: gender differences in relationship and parenting challenges among low-income, young parents

The need for parenting and relationship strengthening programs is important among low-income minority parents where the burden of relational and parental stressors contributes to relationship dissolution. We examine these stressors among young parents. Data were collected from four focus groups (N = 35) with young parents. Data were audio-recorded and transcribed. Inductive coding was used to generate themes and codes, and analysis was completed using NVivo. Relationship and parenting challenges, values, and areas of need were the three major themes that emerged. Women's relationship challenges were family interference and unbalanced parenting, and men reported feeling disrespected and having limited finances. Common relationship challenges for women and men were family interference and unbalanced parenting. Both genders valued trust, communication, and honesty in relationships. Areas of need for women and men included: improving communication and understanding the impact of negative relationships on current relationships. Parenting challenges for women were unbalanced parenting, child safety, and feeling unprepared to parent; men reported limited finances. Both genders valued quality time with child to instill family morals. Areas of need for women and men included learning child discipline techniques and increasing knowledge about child development. Finally, women and men have relationship and parenting similarities and differences. Young parents are interested in learning how to improve relationships and co-parent to reduce relationship distress, which could reduce risk behaviors and improve child outcomes.

What's love got to do with it: Relationship functioning and mental and physical quality of life among pregnant adolescent couples

The study objective was to describe relationship adjustment and its association with mental and physical quality of life for young couples expecting a baby. 296 young pregnant couples recruited from urban obstetric clinics reported on relationship strengths (e.g., equity, romantic love, and attractiveness), relationship risks (e.g., attachment, intimate partner violence), external family support, relationship adjustment, and mental and physical quality of life. Using the Actor Partner Interdependence Model we assessed both actor and partner effects of relationship variables on relationship adjustment and quality of life. Sixty-one percent of couples had at least one member with moderate or severe relationship distress. Lower attachment avoidance, lower attachment anxiety, higher relationship equity, lack of intimate partner violence, feelings of love, perceived partner attractiveness, and family support of the relationship related to better relationship adjustment. Associations were fairly consistent across gender. Better relationship adjustment related to more positive mental and physical quality of life for both young women and men. Our results highlight the potential importance of strong relationships on the well-being of expecting parents. Our results suggest that secure attachments, equitable relationships, feelings of love, and a lack of violence may be particularly important in having strong relationships and improved mental and physical health during pregnancy.

Pathological Vaginal Discharge among Pregnant Women: Pattern of Occurrence and Association in a Population-Based Survey

This study aimed to assess the prevalence of pathological vaginal discharge and to describe risk factors associated with pregnant women. All women living in the city of Rio Grande, Southern Brazil, who gave birth in 2010 were included in the study. A standardized questionnaire was administered to collect information on demographic, reproductive, and health-related factors and morbidity during pregnancy. The chi-square test was used to compare proportions, and multivariate Poisson regression with robust variance was performed. Of the 2,395 women studied, 43% had pathological vaginal discharge during pregnancy. The adjusted analysis showed that younger women of lower socioeconomic condition, those with a past history of abortion, vaginal discharge in a previous pregnancy, and treated for depression, anemia, and urinary tract infection during their current pregnancy, were more likely to have pathological vaginal discharge. Vaginal discharge during pregnancy was highly prevalent in the sample studied calling for proper risk factor management at the primary care level.

Associations of a sexually transmitted disease diagnosis during a relationship with condom use and psychosocial outcomes: (short) windows of opportunity

Few studies have examined whether and how receiving an sexually transmitted disease (STD) diagnosis while in a romantic relationship relates to condom use and psychosocial sexual outcomes. Using dyadic data, we examined associations of a personal or a partner's STD diagnosis during a relationship with condom use, monogamy intentions, condom intentions and attitudes, and STD susceptibility and communication. Because beliefs about how the STD was acquired may shape associations with behavior and cognitions, gender and suspecting that one's partner had other sexual partners (i.e., partner concurrency) were examined as moderators. Participants were 592 individuals in 296 couples expecting a baby; 108 individuals had been diagnosed with an STD during the relationship. Personal STD diagnosis was unrelated to outcomes or was associated with increased risk. A partner's diagnosis related to more positive condom intentions and attitudes. Among men who suspected concurrency, both a personal and a partner's STD diagnosis were associated with less condom use. Receiving the STD diagnosis during pregnancy was associated with greater susceptibility and marginally greater condom use. Results suggest potential benefits of enhancing communication and encouraging joint risk reduction counseling among couples, engaging men more fully in preventive efforts, and capitalizing on the short window during which risk reduction occurs.

Exploring why young African American women do not change condom-use behavior following participation in an STI/HIV prevention intervention

Human immunodeficiency virus (HIV) interventions can significantly reduce risky sexual behaviors among vulnerable populations. However, not everyone exposed to an intervention will reduce their sexual risk behavior. This qualitative study sought to identify factors associated with young African American females' lack of increase in condom use post-participation in an HIV prevention intervention. Semi-structured interviews were conducted with 50 young African American women (18-23 years; approximately half were mothers) after participating in a demonstrated effective HIV prevention intervention; 24 did not increase condom use post-intervention. Interviews were thematically coded for barriers to condom-use post-intervention. Although nearly all young women reported partner-associated challenges to using condoms, there were relational differences observed among those who changed their condom use versus those who did not. Many 'non-changers' were engaged in non-stable 'on and off' relationships, with high rates of infidelity, often with the father of their child, in which they were fearful of requesting condom use. 'Non-changers' also reported more substance use, feeling incapable of change and not thinking about condom use. Thus, future HIV prevention efforts may benefit from incorporating strategies on how young mothers can maintain a non-sexual relationship with their child's father, as well as elaborating on the intersection of substance use and risky sexual decision-making.

Prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae and repeat infection among pregnant urban adolescents

BACKGROUND

Negative maternal and fetal consequences associated with Chlamydia trachomatis and Neisseria gonorrhoeae during pregnancy make diagnosis essential. The Centers for Disease Control and Prevention recommend routine screening for sexually transmitted infections at the first prenatal visit, and third trimester repeat screening, specifically for C. trachomatis, is recommended for women under age 25 or at increased infection risk. The effect of repeat screening on diagnosis during pregnancy is not well documented among adolescents.

METHODS

A prospective cohort of 125 pregnant adolescents with at least one prenatal screening for C. trachomatis and N. gonorrhoeae was analyzed. All participants received prenatal care and delivered at one urban teaching hospital in Washington, DC. Screening results were documented for both sexually transmitted infections. Descriptive and univariate analyses were performed to describe disease prevalence.

RESULTS

Of pregnant adolescents, 31% were diagnosed with either C. trachomatis or N. gonorrhoeae infection during pregnancy. Of the 75% (95/125) of patients who had more than one screening test, 11% (10/95) had a reinfection, and 7% (7/95) had a new infection on repeat testing. Nine percent (9/95) had recurrent C. trachomatis, whereas 4% (4/95) had a new diagnosis. Three percent (3/95) had recurrent N. gonorrhoeae, whereas 4% (4/95) had a new diagnosis. Some experienced coinfection at either initial or repeat testing.

CONCLUSIONS

Screening for C. trachomatis and N. gonorrhoeae is recommended during pregnancy. In this sample of pregnant adolescents, the overall high incidence and recurrence of C. trachomatis and N. gonorrhoeae support Centers for Disease Control and Prevention screening and rescreening recommendations, regardless of initial test results.

Let's stay together: relationship dissolution and sexually transmitted diseases among parenting and non-parenting adolescents

Relationships influence sexual risk and maternal-child health. Few studies have assessed relationship dissolution and its association with sexually transmitted diseases (STD) among adolescent parents. Our study aimed to describe relationship dissolution among 295 parenting and non-parenting adolescents over an 18-month period and how it related to STD incidence. Results showed that nonparenting adolescents in a relationship with someone other than their baby's father were more likely to have a relationship dissolution over an 18-month period compared to those in a relationship with the baby's father (OR = 1.69, P < .05). Parenting adolescents who ended their relationship with their baby's father were 3 times more likely to get an STD over the course of the study compared to parenting adolescents who remained with their baby's father (39% vs. 13%). Comparatively, nonparenting adolescents who ended their relationship were only 1.4 times more likely to get an STD compared to non-parenting adolescents who remained with their partner (44% vs. 32%). Our results suggest that prevention programs that incorporate male partners and components that strengthen relationship skills may reduce HIV/STD risk and help adolescents adapt during times of transition such as parenthood.

Economic dependence and unprotected sex: the role of sexual assertiveness among young urban mothers

In the USA, sexual intercourse is the leading route of human immunodeficiency virus transmission among women, primarily through their main partner. Because male condom use is not directly under a woman's control, gender inequalities may help shape this sexual risk behavior. To examine this association, data came from follow-up interviews of young, primarily minority, pregnant women enrolled in a prospective, randomized controlled trial. Specifically, we aimed to determine the relationship between economic dependence on a male partner and condom use, and to establish whether this relationship was mediated by sexual assertiveness. Overall, 28% of women reported being economically dependent on a male partner. Young women dependent on a male partner were 1.6 times more likely to report not using a condom at last sex than women not dependent on their partner (95% confidence interval = 1.11-2.32; p = 0.01). Sexual assertiveness mediated the relationship between economic dependence and condom use (Sobel = 2.05, p = 0.04). Coupled with past research, this study supports the premise that sexual behaviors may be rooted in a complex web of social determinants. Addressing gender inequalities in contextual factors may promote healthier decisions within sexual relationships.

Prevalência e fatores associados à percepção de ocorrência de corrimento vaginal patológico entre gestantes

Este estudo teve por objetivo medir a prevalência e identificar fatores associados à percepção de corrimento vaginal patológico por gestantes residentes em Rio Grande, Rio Grande do Sul, Brasil. Aplicou-se questionário padronizado a todas as parturientes nas maternidades do município em 2007. Utilizou-se teste do qui-quadrado para comparar proporções e análise multivariável por regressão de Poisson. A prevalência de corrimento vaginal foi de 40%. Análise ajustada mostrou as seguintes razões de prevalência: 1,6 (1,4-1,8) para adolescentes; 1,3 (1,1-1,6) para aquelas com até oito anos de escolaridade; 1,3 (1,1-1,5) para aquelas que ingeriram álcool; 2,0 (1,8-2,2) para aquelas que referiram corrimento vaginal em gestação anterior; 1,4 (1,3-1,6) para infecção urinária na gestação atual; prematuridade em gestação anterior mostrou-se protetor com RP = 0,8 (0,7-0,9). Os serviços de saúde deveriam priorizar diagnóstico e tratamento de corrimento vaginal entre gestantes adolescentes, de baixa renda familiar e escolaridade, com história prévia de corrimento em gravidez anterior e infecção urinária na gravidez atual.

Pregnancy as a window of opportunity for HIV prevention: effects of an HIV intervention delivered within prenatal care

OBJECTIVES

We sought to determine whether an HIV prevention program bundled with group prenatal care reduced sexually transmitted infection (STI) incidence, repeat pregnancy, sexual risk behavior, and psychosocial risks.

METHODS

We conducted a randomized controlled trial at 2 prenatal clinics. We assigned pregnant women aged 14 to 25 years (N = 1047) to individual care, attention-matched group care, and group care with an integrated HIV component. We conducted structured interviews at baseline (second trimester), third trimester, and 6 and 12 months postpartum.

RESULTS

Mean age of participants was 20.4 years; 80% were African American. According to intent-to-treat analyses, women assigned to the HIV-prevention group intervention were significantly less likely to have repeat pregnancy at 6 months postpartum than individual-care and attention-matched controls; they demonstrated increased condom use and decreased unprotected sexual intercourse compared with individual-care and attention-matched controls. Subanalyses showed that being in the HIV-prevention group reduced STI incidence among the subgroup of adolescents.

CONCLUSION

HIV prevention integrated with prenatal care resulted in reduced biological, behavioral, and psychosocial risks for HIV.

[Self-reported vaginal discharge among pregnant women in an urban area in Southern Brazil: prevalence and associated factors]

The purpose of this study was to determine the prevalence and risk factors associated with self-reported vaginal discharge among pregnant women in the city of Rio Grande, South Brazil. Using a cross-sectional design, a standard interview was applied to pregnant women at home by previously trained interviewers, covering the following: demographic, reproductive, and socioeconomic data, household conditions, health care, and illnesses during pregnancy, including vaginal discharge. The chi-square test was used to compare proportions, and Poisson regression was used in the multivariate analysis. Among the 339 pregnant women interviewed, 52% reported vaginal discharge. The following variables were significantly associated with the outcome: age (prevalence rate, PR = 1.49), marital status (PR = 1.31), urinary tract infection (PR = 1.56), hyperglycemia (PR = 1.48), use of an intrauterine device (PR = 2.35), and history of preterm delivery (PR = 1.37), with oral contraception showing a protective effect (PR = 0.79). Prevalence of self-reported discharge was high among this group of pregnant women. Several risk factors were also identified for the disease under study. These findings can contribute to the implementation of preventive interventions.

Sexually transmitted diseases and risk behaviors among pregnant women attending inner city public sexually transmitted diseases clinics in Baltimore, MD, 1996-2002

OBJECTIVE

To determine the prevalence of sexually transmitted diseases (STDs) and characterize behavioral correlates among pregnant women attending inner city public STD clinics.

STUDY DESIGN

A retrospective study of 2303 pregnant women frequency matched by clinic and year of visit to 2303 nonpregnant women seeking services during years 1996 to 2002 at public STD clinics in Baltimore, MD.

RESULTS

On average, 329 pregnant women attended Baltimore City STD clinics each year during 1996 to 2002. Forty-six and a half percent of pregnant women knew they were pregnant when they presented to the STD clinic. Although pregnant women were younger (23.3 vs. 28.3 years of age, P <0.01) and more likely to have sought STD clinical services in the past (55.4% vs. 51.5%, P <0.01), they were less likely to report high-risk sexual behaviors such as new (4.6% vs. 7.0%, P <0.01) or multiple sex partners (11.6% vs. 13.9%, P <0.01) than nonpregnant women. However, prevalence of gonorrhea (4.8% pregnant vs. 4.2%), chlamydia (9.9% vs. 7.7%), trichomoniasis (12.4% vs. 12.0%), and early syphilis (1.5% vs. 1.2%) was high, and both groups were equally as likely to have any STD.

CONCLUSION

The prevalence of STDs was similar for pregnant and nonpregnant women attending the inner city public STD clinics, despite differences in risk factors for STDs. Understanding the impact of STDs on perinatal outcomes among this population and developing targeted interventions to reduce STD-related maternal and infant morbidity are critical public health issues.

Prevalence of sexually transmitted infections in HIV-1 infected pregnant women in Europe

We investigated prevalence of sexually transmitted infections (STI) in a cohort of HIV-1-infected pregnant women and described factors associated with STI diagnosis, as a nested study within the European Collaborative Study (ECS). The ECS is a cohort study in which HIV-infected pregnant women are enrolled and their children followed from birth, according to standard clinical and laboratory protocols. Information on STIs diagnosed during pregnancy was collected retrospectively from the antenatal records of women enrolling between January 1999 and October 2005; other variables were obtained from the ECS prospective database. A total of 1,050 women were included: 530 in Western Europe and 520 in Ukraine. Syphilis was the most common bacterial STI (2% prevalence, 95% CI 1.2-3.0). Prevalence of HPV-related genital lesions was 8.6% (95%CI 6.9-10.4) and prevalence of Trichomonas vaginalis was 12.1% (95%CI 10.2-14.2). Women in Ukraine (AOR 10.7, 95%CI 3.7-30.5), single women (AOR 3.9, 95%CI 1.2-12.7), sexual partners of injecting drug users (AOR 3.8, 95%CI 1.4-10.4) and women with CD4 counts <200 cells/mm(3) (AOR 5.4, 95%CI 1.0-28.1) were at increased risk of diagnosis with Chlamydia trachomatis, syphilis or Trichomonas vaginalis. African origin (AOR 1.9, 95%CI 1.1-3.3) and CD4 count <200 cells/mm(3) (AOR 3.4, 95%CI 1.5-7.8) were associated with HSV-2 and/or HPV-related genital lesions. Antenatal screening should be considered an effective tool for diagnosis, treatment and prevention of further transmission of STIs. HIV-infected women should receive adequate screening for STIs during pregnancy together with appropriate counseling and follow-up for treatment and prevention.

Using clinical classification trees to identify individuals at risk of STDs during pregnancy

CONTEXT

Few studies have used classification tree analysis to produce empirically driven decision tools that identify subgroups of women at risk of STDs during pregnancy. Such tools can guide care, treatment and prevention efforts in clinical settings.

METHODS

A sample of 647 women aged 14-25 attending two urban obstetrics and gynecology clinics in 2001-2004 were surveyed in their second and third trimesters. Baseline predictors at the individual, dyad, and family and community levels were used to develop a classification tree that differentiated subgroups of women by STD incidence at 35 weeks' gestation. Logistic regression analyses were conducted to assess whether the classification tree groups or commonly used risk factors better predicted STD incidence.

RESULTS

Nineteen percent of women had an incident STD during pregnancy. Classification tree analysis identified three subgroups with a high STD incidence (33-61%), one with a moderate incidence (16%) and three with a low incidence (6-11%). Women in subgroups with high STD incidence included those not living with the partner with whom they conceived and those who had a moderate or a high level of depression, a history of STDs and a low level of social support. A logistic regression model using groups defined by the classification tree analysis had better predictive ability than one using common demographic and sexual risk predictors.

CONCLUSION

This classification tree identified risk factors not captured by traditional risk screenings, and could be used to guide STD treatment, care and prevention within the prenatal care setting.

Preventing repeat teen pregnancy: postpartum depot medroxyprogesterone acetate, oral contraceptive pills, or the patch?

STUDY OBJECTIVE

To prospectively evaluate the repeat teen pregnancy rates, within one year of delivery, among adolescents who choose the contraceptive patch (Ortho Evra) versus oral contraceptive pills (OCP) versus Depot Medroxyprogesterone Acetate (Depo Provera, DMPA) for postpartum contraception.

DESIGN

Observational, prospective cohort study. Comparison groups are postpartum teens, who self-select the contraceptive patch (n = 55) versus DMPA (n = 142) versus OCPs (n = 55) immediately postpartum.

SETTING

Medical University of South Carolina, a tertiary medical center.

PARTICIPANTS

Postpartum teens, 11-19 years old; 72% were African American, and 96% qualified for Medicaid insurance.

INTERVENTIONS

A structured telephone interview was performed every 3 months.

MAIN OUTCOME MEASURES

The primary outcome measure was a repeat pregnancy within 12 months of the index delivery. Secondary outcome variables were contraceptive continuation rates, reasons for discontinuation, side effects and condom usage.

RESULTS

At 1-year follow-up, repeat pregnancy rates were 14.2%, 29.7%, and 31.8% among DMPA, OCP, and patch users respectively (P = 0.02). DMPA users were significantly more likely to be using any form of hormonal contraception 1 year postpartum than patch or OCP users. Condom use was similarly low among all cohorts.

CONCLUSION

Adolescents who choose DMPA for postpartum contraception are significantly less likely to become pregnant within 1 year of delivery, as compared to teens who choose OCPs or the patch.

Avoidance, anxiety, and sex: the influence of romantic attachment on HIV-risk among pregnant women

Most unprotected sex occurs in close relationships. However, few studies examine relational factors and sexual risk among high-risk populations. Romantic Attachment Theory states that individuals have cognitive working models for relationships that influence expectations, affect, and behavior. We investigated the influence of attachment avoidance and anxiety on sexual beliefs (e.g., condom use beliefs, self-efficacy), behavior (e.g., condom use, multiple partners, unprotected sex with risky partners), and sexually transmitted infections (STIs) among 755 high-risk, young pregnant women (ages 14-25) recruited from urban prenatal clinics. Attachment anxiety predicted sexual beliefs, condom use, and unprotected sex with risky partners controlling for demographic variables. Sexual beliefs did not mediate the relationship between attachment orientation and sexual behavior. Current relationship with the father of the baby did mediate the effect of attachment anxiety on multiple partners and STIs. Results indicate the importance of including general relational factors, such as attachment, in HIV prevention.

Prenatal and parenting stress on adolescent maternal adjustment: identifying a high-risk subgroup

OBJECTIVES

Identifying adolescents who are at increased risk for a particularly difficult pregnancy and adjustment into parenthood is important, as the physical and psychological development of their infants rest in the well-being of these new mothers. This study aims to examine the effects of prenatal stress and parenting stress and the association with: (1) adolescent maternal adjustment; and (2) postpartum emotional distress.

METHODS

In a prospective longitudinal cohort study, 154 pregnant adolescents (age 14-19) from 10 public clinics were interviewed four times from the third trimester of pregnancy to 16 months postpartum. Planned comparisons of four stress groups were used to compare mean scores for measures of feelings about motherhood, infant care, parenting competency, and emotional distress.

RESULTS

Adolescent mothers who experienced high prenatal stress and high parenting stress had lower maternal adjustment (i.e., fewer positive feelings about motherhood, less infant care, and low parenting competency) and high postpartum emotional distress. Even when compared to adolescent mothers who experienced prenatal or parenting stress only, these adolescents were still at a greater disadvantage.

CONCLUSIONS

Results suggest that adolescents who experience high stress during and after pregnancy are at increased risk for difficult maternal adjustment and high postpartum emotional distress. Findings support the need for health services targeting this subgroup of adolescent mothers, including both prenatal and parenting support. Early intervention to increase maternal adjustment and decrease emotional distress should remain a priority in facilitating the most optimal maternal and child health outcomes.

The influence of power on HIV risk among pregnant women in rural Haiti

Given that condom use is not directly under a woman's control, the sexual division of power may play an important role in sexual behavior among pregnant women. We assessed the influence of factors related to the theory of gender and power (e.g., relationship power, abuse history, and sexual communication) on sexual behavior (e.g., two or more partners in the year prior to pregnancy, condom use, condom-use intentions, and STI diagnosis) among 196 pregnant women recruited from five community dispensaries in rural Haiti. Results showed that gender and power factors significantly related to sexual behavior. Gender and power factors were most significant for condom use and intention to use condoms, accounting for 18 and 25% of the variance above and beyond HIV knowledge and demographic covariates, respectively. These results suggest the need to create prevention interventions that restore power imbalances, provide support for women suffering abuse, and strengthen communication skills.

Health-risk behaviors in a sample of first-time pregnant adolescents

OBJECTIVE

The purpose of this study was to assess the frequency of prenatal health-risk behaviors (substance use, sexual risk taking, and prenatal class attendance) among a nonrandom sample of first-time pregnant adolescents.

DESIGN

The design is descriptive.

SAMPLE

145 ethnically diverse first-time pregnant adolescents aged 15-18 years.

MEASUREMENT

Health behavior questions modified from the Center for Disease Control's Youth Risk Behavior Surveillance System.

RESULTS

The health-risk behavior most modified during pregnancy was alcohol use (64/145 drank but quit and 1/145 did not quit). Of the 52/145 who used street drugs, nine continued despite pregnancy. Of the 75/145 who smoked early in pregnancy, 39 continued. The majority did not use a condom at last sexual intercourse. Approximately half attended a prenatal class and half attended a teen parenting class.

CONCLUSION

Health-risk behaviors captured by birth certificate data are thought to be underreported for all age groups, and the prevalence of health-risk behaviors in this sample of pregnant teens was often greater than the most recent national trend data available. The magnitude of the effects of health-risk behaviors on pregnancy outcomes necessitates improved data gathering to enhance planning and evaluation of research and interventions at community, system, and individual/family levels.

Chlamydia trachomatis infections in neonates and young children

In 1911, Lindner and colleagues identified intracytoplasmic inclusions in infants with a nongonococcal form of ophthalmia neonatorum called inclusion conjunctivitis of the newborn (ICN). Mothers of affected infants were found to have inclusions in their cervical epithelial cells, fathers of such infants had inclusions in their urethral cells, and the epidemiology of sexually transmitted chlamydial infections was revealed. Fifty years later, chlamydial isolation procedures were developed, and studies again demonstrated Chlamydia trachomatis as an etiology of ICN and the female birth canal as the reservoir. In the late 1970s, a report by Beem and Saxon described respiratory tract colonization and a distinct pneumonia syndrome in infected infants. Genital chlamydial infection is recognized as the world's most common sexually transmitted disease, with estimates of greater than 4 million new infections occurring annually in the United States. Although most C. trachomatis infections in men and women are asymptomatic, infection can lead to severe reproductive complications in women. The high prevalence in women of child-bearing age results in exposure of an estimated 100,000 neonates in the United States annually. Many of these infants develop conjunctivitis, pneumonia, or both in the first few months of life. Clinical features, diagnosis, treatment, and approaches to prevention of conjunctivitis and pneumonia in the newborn and young infant are reviewed here. Appropriate testing for chlamydial infection in a pediatric victim of sexual assault and the implications of identifying C. trachomatis in suspected cases of childhood sexual abuse also are reviewed.

Knowledge of sex partner treatment for past bacterial STI and risk of current STI

OBJECTIVES

Effective partner management is critical in reducing the spread of bacterial sexually transmitted infections (STIs). The purpose of this study was to determine the relation between knowledge of partner treatment for a past STI and current infection in the index patient.

METHODS

In a cross sectional analysis, 97 adolescent females sampled from community based health clinics reported that they had a past diagnosis of chlamydia or gonorrhoea in structured, face to face interviews. At the time of the interview, adolescents were also tested for chlamydia and gonorrhoea using urine based ligase chain reaction testing.

RESULTS

66% of the adolescents reported knowing that their partner was treated for the past infection. Those who knew their partner was treated were less likely to have a current infection, compared to those who did not know (11% v 30%, adjusted odds ratio and 95% confidence interval 4.46 (1.41 to 14.29), p<0.05). Correlates of not knowing the sex partner was treated included younger age and being in new sex partnership.

CONCLUSIONS

Efforts to encourage young women to follow up directly with their partners regarding treatment may help to reduce repeat infections and further spread. Furthermore, alternative strategies such as patient delivered therapy may help with partner treatment in this vulnerable population.

Systematic review of sexual risk among pregnant and mothering teens in the USA: pregnancy as an opportunity for integrated prevention of STD and repeat pregnancy

Behaviors that lead to teen pregnancy also place young women at risk for STDs and repeat pregnancy. Compared to the broad literature on adolescent sexual risk behavior, our understanding of sexual risk in pregnant/mothering teens lags far behind. Primary objectives of this systematic review (1981-2003) of pregnant/mothering teens were to: (1) document rates of STD, repeat pregnancy, condom use, and contraception; (2) identify correlates of these biological and behavioral outcomes; (3) review sexual risk reduction interventions; and (4) discuss directions for future research and implications for clinical care. Fifty-one studies met inclusion criteria. Rates of STD and repeat pregnancy were high, with the majority of teens engaging in unprotected sex during and after pregnancy. An Ecological Model of Sexual Risk, based on Bronfenbrenner's (1989) Ecological Systems Theory, was proposed to organize findings on correlates of sexual risk. Improvements in research, including integration of outcomes and risk factors, stronger methodologies, and standardized assessments, are essential. Results suggest that teen pregnancy is a marker for future sexual risk behavior and adverse outcomes, and that pregnant/mothering teens need hybrid interventions promoting dual use of condoms and hormonal contraception. Pregnancy may provide a critical "window of opportunity" for sexual risk reduction.

Sexual risk following a sexually transmitted disease diagnosis: the more things change the more they stay the same

The purpose of this study is to assess changes in sexual risk behaviors, attitudes toward using condoms, and perceived susceptibility to fiuture STDs for adolescent females who recently were diagnosed with an incident STD compared to those who were not diagnosed with an incident STD. Adolescent females (N = 308) were assessed at two time points, 6 months apart. Ninety-two participants were diagnosed with an STD, and 216 were not diagnosed with an STD in between the two time points. Results indicated that adolescents did not significantly change their behaviors, attitudes, or perceptions following the diagnosis of an incident STD compared to those who were not diagnosed with an incident STD. This suggests that an STD diagnosis alone is not sufficient to motivate adolescent females to reduce their sexual risk behavior and change their sexual risk attitudes and perceptions.

An exploration of the relationship between youth assets and engagement in risky sexual behaviors

PURPOSE

To examine the relationship between specific youth assets and adolescents' engagement in risky sexual behaviors, as measured by an Aggregate Sexual Risk score, and to specifically explore which youth assets and demographic variables were predictive of youth engagement in risky sexual intercourse.

METHODS

A total of 2108 sexually active high school students attending public high schools in a southern state completed a self-report questionnaire that measured youth assets. Based upon responses to items measuring risk behaviors, an Aggregate Sexual Risk score was calculated for each student. Unconditional logistic regression and multivariate logistic regression analyses were conducted to examine the relationships between the assets and the Aggregate Risk Score. Four separate analyses (white females, white males, black females, and black males) were conducted.

RESULTS

In general, the patterns in all four groups indicated that students who had an Aggregate Risk Score of > or = 3 (high risk) possessed less of the measured youth assets. The assets that were most significantly associated with engagement in risky sexual behaviors included self peer values regarding risky behaviors, quantity of other adult support, and youths' empathetic relationships. Thus, students who reported not having these assets were significantly more likely to engage in the risky sexual behaviors.

CONCLUSIONS

Results underscore the relationship of specific youth assets to sexual risk behaviors. Health researcher and practitioners who work to prevent teen pregnancy and sexually transmitted infections among teenagers need to understand and acknowledge these factors within this population so that the assets can be built or strengthened.

Incidence of sexually transmitted diseases in Hokkaido, Japan, 1998 to 2001

The objective of this study was to provide precise data on the incidence of sexually transmitted diseases (STDs) in Hokkaido. The goal of this prospective surveillance, study was to clarify the STD incidence between 1998 and 2001 in Hokkaido, Japan. The incidence of gonococcal infection in men was found to be 127-199 per 100 000 people per year, which was three or four times higher than that for women. Female genital chlamydial infection had an incidence of 300-400 with a female to male ratio of two or three to one. Younger adults had higher incidences of gonococcal and chlamydial infections than older people. In conclusion, the current study of STDs revealed high incidences of gonococcal and chlamydial infections in the Hokkaido area, and there was no decreasing trend in STD incidence during these 4 years.

New sex partner acquisition and sexually transmitted disease risk among adolescent females

PURPOSE

To determine the association between new sex partner acquisition and incident STDs, to describe predictors of acquiring a new sex partner, and to compare new and established sex partnerships among adolescent females.

METHODS

Interview data and biological specimens for STD testing were collected from a sample of 411 adolescent females (average age 17.3 years, 44% black and 42% Hispanic) enrolled in a longitudinal study. The relationship between having a new sex partner and incident STD infection was estimated with logistic regression.

RESULTS

Acquisition of a new sex partner during the 12-month follow-up period was common (24%) and significantly associated with an incident STD infection (OR = 3.0, 95% CI = 1.6-5.7). Predictors of new partner acquisition were younger age, younger age at first intercourse, and alcohol or drug use before sex in past 30 days. Being in a new partnership was significantly associated with greater uncertainty about the partners' STD history and recent sex with others.

CONCLUSIONS

Being in a new sex partnership is an important predictor of incident STD infection. Awareness of this risk can help clinicians identify individuals who are more likely to get STDs and therefore target STD testing and appropriate prevention messages.

Developments in the screening for Chlamydia trachomatis: a review

Many studies have evaluated selective screening criteria for women in various settings. Most have concluded and all guidelines recommend that all women aged < 25 be screened yearly for C. trachomatis infection. Behavioral criteria, such as the number of sex partners, new or more than one sex partners, and previous infection, also can serve as criteria for screening women aged > 25. Because re-infection rates are high and occur within a few months, complications may be reduced further if partners are treated and women rescreened 4 to 6 months after initial infection. Revised recommendations for C. trachomatis screening programs have stated that more frequent screening may be considered among women < 20 and those with recent infection. Screening in nontraditional settings and careful evaluation of local prevalence and risk factor information should be encouraged. Private providers and emergency room providers should discuss screening recommendations and adopt a C. trachomatis screening policy for the population they serve. The HEDIS measure should serve to encourage at least annual screening of 15- to 25-year-old sexually active females through providers linked to managed care organizations. In general, high yields (ie, percentage of tests that are positive) in nontraditional settings and enhanced feasibility and acceptability of urine-based tests may encourage further innovative approaches to reach and screen populations at risk. Several issues remain to be addressed to increase the effectiveness of screening efforts. If more sensitive amplification tests are used widely, more infected persons will be identified and treated, and transmission patterns may change, particularly if partner treatment also occurs. Current screening criteria should continue to be re-evaluated. An important issue that affects testing methods includes the possible need for confirmation testing when using NAATs if the prevalence of C. trachomatis is less than 2%. If the sensitivity of an NAAT is 85% and specificity is 99%, in a hypothetical population of 10,000 with a prevalence of 2%, the positive predictive value is 170/268 (63%). A second important issue affecting testing methods and feasibility of using NAATs for screening large numbers of individuals is the pooling of urine specimens, which has been evaluated in several studies and found to be very effective for reducing costs. A research issue for pooling is the determination of the most cost-effective prevalence levels for pooling. An additional research question is in which populations should a NAAT be used for detection of C. trachomatis and N. gonorrhoeae. There are no recommendations for the routine screening of men because of the paucity of data showing that this strategy can reduce sequelae. The CDC is conducting a multisite study to examine the feasibility, acceptability, and usefulness of screening of asymptomatic men. There are a few studies have determining cost-effective prevalence threshold levels, particularly with NAATs. A recently developed decision analysis model by CDC designed to maximize the effectiveness of screening strategies for C. trachomatis infections may be useful for decision makers. It is intended to serve as an easy and flexible tool to determine cost effectiveness at a local level and takes into account positivity rates and test performance characteristics (SOCRATES). It is unclear if recurrent infection is caused by true re-infection by the same or a different partner or recurrence of initial infection. Recurrence may be caused by persistence of C. trachomatis or antibiotic resistance. This distinction is of scientific interest because the appropriate intervention differs (eg, identification of risk factors for the former and microbiologic investigations for the latter). Effective partner management and retesting are critical to reducing sequelae of C. trachomatis infection. Screening for C. trachomatis infection remains an essential component of C. trachomatis control. It is cost effective, most infections are asymptomatic, and symptom-based health care seeking and testing identify few of those infected. The likelihood that opportunities for screening are missed is high particularly in non-STD clinic settings. Local studies using NAATs to determine C. trachomatis prevalence and risk factors are helpful to health care providers so they can make evidence-based decisions on who to screen. The use of nontraditional, non-clinic-based test settings should be explored further. We have focused on summarizing the medical evidence regarding recommendations for screening for C. trachomatis. High-risk populations for C. trachomatis infection may overlap with populations for other STDs, and comprehensive STD prevention programs that involve a range of STD service providers are needed to successfully reduce the STD-related health burden in the population.

Misperceived risk among female adolescents: Social and psychological factors associated with sexual risk accuracy

This study of 411 urban female adolescents had 3 objectives: (a) assess the relationship between perceived risk and sexual risk behavior (condom use, number of partners, partner risk, presence of STDs, and aggregate sexual risk), (b) assess the accuracy of risk perceptions, and (c) identify variables related to inaccurate sexual risk perceptions. Participants were classified as accurate or inaccurate risk perceivers on the basis of actual sexual behavior and perceived risk. Accurate versus inaccurate risk perceivers were compared on psychological maintenance variables (self-esteem, distress, and coping), relationship context variables (partnership duration and pressure to have unprotected sex), and risk knowledge at different levels of sexual risk. Approximately half of the participants underestimated the risk of their sexual behavior. Accurate and inaccurate risk perceivers differed on risk knowledge, partnership duration, and pressure to have unprotected sex.
