Abstract
PURPOSE The Michigan Department of Health and Human Services, in collaboration with St. John Providence Health System, initiated voluntary school-wide sexually transmitted disease (STD) screenings in four Detroit public high schools. We sought to assess the cost-effectiveness of the STD screening program from 2010 to 2015, with a focus on chlamydia. METHODS The costs and effectiveness of the school-based screening were compared with those of a "no school screening" scenario using a healthcare system perspective. A decision tree model was constructed to project cases of chlamydia, epididymitis, and pelvic inflammatory disease (PID) in each of the two scenarios among students tested positive and their partners. Health effects were measured as cases of PID prevented, and quality-adjusted life-years (QALYs) gained. Cost estimates included program costs, chlamydia testing/treatment costs in the absence of school screening, and treatment costs for epididymitis, PID, and PID sequelae. The incremental cost-effectiveness ratio (ICER) was measured as cost/QALY gained. Multivariate sensitivity analyses were conducted on key parameter estimates and assumptions used. RESULTS Under base-case assumptions, at a total program cost of $333,848 over 5 years, the program prevented an estimated 1.9 cases of epididymitis and 17.3 cases of PID, resulting in an ICER of $38,235/QALY gained (yearly ICER ranging from $27,417 to $50,945/QALY). Of 10,000 Monte Carlo simulation runs, the yearly ICER remained ≤$50,000/QALY in 64%-98% of the simulation runs. CONCLUSIONS We found favorable cost-effectiveness ratios for Michigan's school-wide STD screening program in Detroit. School-based STD screening programs of this type warrant careful considerations by policy makers and program planners.

Abstract
BACKGROUND We conducted systematic reviews on the benefits and harms of screening compared with no screening or alternative screening approaches for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) in non-pregnant sexually active individuals, and on the relative importance patients' place on the relevant outcomes. Findings will inform recommendations by the Canadian Task Force on Preventive Health Care. METHODS We searched five databases (to January 24, 2020), trial registries, conference proceedings, and reference lists for English and French literature published since 1996. Screening, study selection, and risk of bias assessments were independently undertaken by two reviewers, with consensus for final decisions. Data extraction was conducted by one reviewer and checked by another for accuracy and completeness. Meta-analysis was conducted where appropriate. We used the GRADE approach to rate the certainty of the evidence. The Task Force and content experts provided input on determining thresholds for important effect sizes and on interpretation of findings. RESULTS Of 41 included studies, 17 and 11 reported on benefits and harms of screening, respectively, and 14 reported on patient preferences. Universal screening for CT in general populations 16 to 29 years of age, using population-based or opportunistic approaches achieving low screening rates, may make little-to-no difference for a female's risk of pelvic inflammatory disease (PID) (2 RCTs, n=141,362; 0.3 more in 1000 [7.6 fewer to 11 more]) or ectopic pregnancy (1 RCT, n=15,459; 0.20 more per 1000 [2.2 fewer to 3.9 more]). It may also not make a difference for CT transmission (3 RCTs, n=41,709; 3 fewer per 1000 [11.5 fewer to 6.9 more]). However, benefits may be achieved for reducing PID if screening rates are increased (2 trials, n=30,652; 5.7 fewer per 1000 [10.8 fewer to 1.1 more]), and for reducing CT and NG transmission when intensely screening high-prevalence female populations (2 trials, n=6127; 34.3 fewer per 1000 [4 to 58 fewer]; NNS 29 [17 to 250]). Evidence on infertility in females from CT screening and on transmission of NG in males and both sexes from screening for CT and NG is very uncertain. No evidence was found for cervicitis, chronic pelvic pain, or infertility in males from CT screening, or on any clinical outcomes from NG screening. Undergoing screening, or having a diagnosis of CT, may cause a small-to-moderate number of people to experience some degree of harm, mainly due to feelings of stigmatization and anxiety about future infertility risk. The number of individuals affected in the entire screening-eligible population is likely smaller. Screening may make little-to-no difference for general anxiety, self-esteem, or relationship break-up. Evidence on transmission from studies comparing home versus clinic screening is very uncertain. Four studies on patient preferences found that although utility values for the different consequences of CT and NG infections are probably quite similar, when considering the duration of the health state experiences, infertility and chronic pelvic pain are probably valued much more than PID, ectopic pregnancy, and cervicitis. How patients weigh the potential benefits versus harms of screening is very uncertain (1 survey, 10 qualitative studies); risks to reproductive health and transmission appear to be more important than the (often transient) psychosocial harms. DISCUSSION Most of the evidence on screening for CT and/or NG offers low or very low certainty about the benefits and harms. Indirectness from use of comparison groups receiving some screening, incomplete outcome ascertainment, and use of outreach settings was a major contributor to uncertainty. Patient preferences indicate that the potential benefits from screening appear to outweigh the possible harms. Direct evidence about which screening strategies and intervals to use, which age to start and stop screening, and whether screening males in addition to females is necessary to prevent clinical outcomes is scarce, and further research in these areas would be informative. Apart from the evidence in this review, information on factors related to equity, acceptability, implementation, cost/resources, and feasibility will support recommendations made by the Task Force.

Abstract
Background Chlamydia screening in high schools offers a way to reach adolescents outside of a traditional clinic setting. Using transmission dynamic modeling, we examined the potential impact of high-school-based chlamydia screening programs on the burden of infection within intervention schools and surrounding communities, under varying epidemiological and programmatic conditions. Methods A chlamydia transmission model was calibrated to epidemiological data from three different settings. Philadelphia and Chicago are two high-burden cities with existing school-based screening programs. Rural Iowa does not have an existing program but represents a low-burden setting. We modeled the effects of the two existing programs to analyze the potential influence of program coverage and student participation. All three settings were used to examine a broader set of hypothetical programs with varying coverage levels and time trends in participation. Results In the modeled Philadelphia program, prevalence among the intervention schools’ sexually active 15–18 years old population was 4.34% (95% credible interval 3.75–4.71%)after 12 program years compared to 5.03% (4.39–5.43%) in absence of the program. In the modeled Chicago program, prevalence was estimated as 5.97% (2.60–7.88%) after 4 program years compared to 7.00% (3.08–9.29%) without the program. In the broader hypothetical scenarios including both high-burden and low-burden settings, impact of school-based screening programs was greater in absolute terms in the higher-prevalence settings, and benefits in the community were approximately proportional to population coverage of intervention schools. Most benefits were garnered if the student participation did not decline over time. Conclusions Sustained high student participation in school-based screening programs and broad coverage of schools within a target community are likely needed to maximize program benefits in terms of reduced burden of chlamydia in the adolescent population.

Abstract
During the 2015-2016 school year, the Florida Department of Health in Duval County hosted Teen Health Centers (TeenHC) at five high schools of Jacksonville providing HIV/STD screening and pregnancy testing. The purpose of this study was to assess the cost-effectiveness of the TeenHC chlamydia screening program and determine at what student participation level, the program can be cost-effective. We assessed the costs and effectiveness of the chlamydia screening program compared with "no TeenHC". Cost-effectiveness was measured as cost per quality-adjusted life years (QALY) gained. At a program cost of US$61,001 and 3% participation rate, the cost/QALY gained was $124,328 in the base-case analysis and $81,014-$264,271 in 95% of the simulation trials, all greater than the frequently citied $50,000/QALY benchmark. The cost/QALY gained could be <$50,000/QALY if student participation rate was >7%. The TeenHC chlamydia screening has the potential to be cost-effective. Future program efforts should focus on improving student participation.

Abstract
We systematically reviewed the literature to assess the effectiveness of school-based programs to prevent HIV and other sexually transmitted infections (STI) among adolescents in the USA. We searched six databases including PubMed for studies published through May 2017. Eligible studies included youth ages 10-19 years and assessed any school-based programs in the USA that reported changes in HIV/STI incidence or testing. We used Cochrane tool to assess the risk of bias and GRADE to determine the evidence quality for each outcome. Three RCTs and six non-RCTs, describing seven interventions, met study inclusion criteria. No study reported changes in HIV incidence or prevalence. One comprehensive intervention, assessed in a non-RCT and delivered to pre-teens, reduced STI incidence into adulthood (RR 0.36, 95% CI 0.23-0.56). A non-RCT examining chlamydia and gonorrhea incidence before and after a condom availability program found a significant effect at the city level among young men 3 years later (RR 0.43, 95% CI 0.23-0.80). The remaining four interventions found no effect. The effect on STI prevalence was also not significant (pooled RR 0.83 from two non-RCTs, RR 0.70 from one RCT). Only one non-RCT showed an increase in HIV testing (RR 3.19, 95% CI 1.24-8.24). The quality of evidence for all outcomes was very low. Studies, including the RCTs, were of low methodological quality and had mixed findings, thus offering no persuasive evidence for the effectiveness of school-based programs. The most effective intervention spanned 6 years, was a social development-based intervention with multiple components, rather than a sex education program, and started in first grade.

Abstract
OBJECTIVES Middle adolescent males are a difficult group to recruit for community sexually transmitted infection (STI) prevention research. We describe a process of community engagement, and venue-based sampling of 14-17-year-old adolescent males, and compare rates of STIs and STI risk behaviors by venue. METHODS Community engagement consisted of (1) informational meetings with organizations; (2) participation in community meetings and events; (3) hiring community members as study personnel; and (4) an adolescent advisory board recruited from the community. Venues were identified and assessed at different times of the day and days of the week using a structured tool. At selected venues, males ages 14-17 years were invited to participate in a brief survey and provide a urine sample and an optional anal swab for DNA-based STI testing. RESULTS Venues were assessed (n = 249), and 31 were selected for recruitment, including parks, apartment complexes, community events, entertainment venues, a community school, and community programs for LGBT (gay, lesbian, bisexual, transgender) and adjudicated youth. We enrolled 667 participants, average age 15.7 years. Participants reported high rates of sexual and STI risk behaviors, but had low rates of STIs. These rates differed by venue, with more structured venues recruiting youth reporting fewer STI risk behaviors and less structured venues within the highest STI prevalence zip code recruiting youth reporting more STI risk behaviors. CONCLUSION Venue-based sampling is a feasible mechanism to target recruitment and enrollment adolescent males with high STI risk behaviors in community settings, with risk profiles varying by setting.

Abstract
BACKGROUND Genital infections caused by Chlamydia trachomatis are the most prevalent bacterial sexually transmitted infection worldwide. Screening of sexually active young adults to detect and treat asymptomatic infections might reduce chlamydia transmission and prevent reproductive tract morbidity, particularly pelvic inflammatory disease (PID) in women, which can cause tubal infertility and ectopic pregnancy. OBJECTIVES To assess the effects and safety of chlamydia screening versus standard care on chlamydia transmission and infection complications in pregnant and non-pregnant women and in men. SEARCH METHODS We searched the Cochrane Sexually Transmitted Infections Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, LILACS, CINAHL, DARE, PsycINFO and Web of Science electronic databases up to 14 February 2016, together with World Health Organization International Clinical Trials Registry (ICTRP) and ClinicalTrials.gov. We also handsearched conference proceedings, contacted trial authors and reviewed the reference lists of retrieved studies. SELECTION CRITERIA Randomised controlled trials (RCTs) in adult women (non-pregnant and pregnant) and men comparing a chlamydia screening intervention with usual care and reporting on a primary outcome (C. trachomatis prevalence, PID in women, epididymitis in men or incidence of preterm delivery). We included non-randomised controlled clinical trials if there were no RCTs for a primary outcome. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion, extracted data and assessed the risk of bias. We resolved disagreements by consensus or adjudication by a third reviewer. We described results in forest plots and conducted meta-analysis where appropriate using a fixed-effect model to estimate risk ratios (RR with 95% confidence intervals, CI) in intervention vs control groups. We conducted a pre-specified sensitivity analysis of the primary outcome, PID incidence, according to the risks of selection and detection bias. MAIN RESULTS We included six trials involving 359,078 adult women and men. One trial was at low risk of bias in all six specific domains assessed. Two trials examined the effect of multiple rounds of chlamydia screening on C. trachomatis transmission. A cluster-controlled trial in women and men in the general population in the Netherlands found no change in chlamydia test positivity after three yearly invitations (intervention 4.1% vs control 4.3%, RR 0.96, 95% CI 0.84 to 1.09, 1 trial, 317,304 participants at first screening invitation, low quality evidence). Uptake of the intervention was low (maximum 16%). A cluster-randomised trial in female sex workers in Peru found a reduction in chlamydia prevalence after four years (adjusted RR 0.72, 95% CI 0.54 to 0.98, 1 trial, 4465 participants, low quality evidence).Four RCTs examined the effect of chlamydia screening on PID in women 12 months after a single screening offer. In analysis of four trials according to the intention-to-treat principle, the risk of PID was lower in women in intervention than control groups, with little evidence of between-trial heterogeneity (RR 0.68, 95% CI 0.49 to 0.94, I2 7%, 4 trials, 21,686 participants, moderate quality evidence). In a sensitivity analysis, the estimated effect of chlamydia screening in two RCTs at low risk of detection bias (RR 0.80, 95% CI 0.55 to 1.17) was compatible with no effect and was lower than in two RCTs at high or unclear risk of detection bias (RR 0.42, 95% CI 0.22 to 0.83).The risk of epididymitis in men invited for screening, 12 months after a single screening offer, was 20% lower risk for epididymitis than in those not invited; the confidence interval was wide and compatible with no effect (RR 0.80, 95% CI 0.45 to 1.42, 1 trial, 14,980 participants, very low quality evidence).We found no RCTs of the effects of chlamydia screening in pregnancy and no trials that measured the harms of chlamydia screening. AUTHORS' CONCLUSIONS Evidence about the effects of screening on C. trachomatis transmission is of low quality because of directness and risk of bias. There is moderate quality evidence that detection and treatment of chlamydia infection can reduce the risk of PID in women at individual level. There is an absence of RCT evidence about the effects of chlamydia screening in pregnancy.Future RCTs of chlamydia screening interventions should determine the effects of chlamydia screening in pregnancy, of repeated rounds of screening on the incidence of chlamydia-associated PID and chlamydia reinfection in general and high risk populations.

Abstract
School-based sexually transmitted disease (STD) screening (SBSS) was designed to provide chlamydia and gonorrhea testing, treatment, and counseling to adolescents in a school setting to overcome some of the difficulties of screening in this population. To inform STD control programs and other entities on decision making about potentially implementing this intervention, we reviewed existing published and gray literature on SBSS from 1998 to 2014. Although they are work-intensive to establish, school-based STD screening programs are a feasible and cost-effective way of testing large numbers of male and female adolescents for chlamydia and gonorrhea, and to provide counseling and treatment to almost all those who are found infected. School-based STD screening programs do not seem to reduce prevalence in either the school or the general adolescent population, although there are currently relatively few studies on large-scale SBSS. More research in this field is needed.

Abstract
SummaryChlamydia trachomatis infections are major public health concerns globally. Of particular grave concern is that the majority of persons with anogenital Chlamydia trachomatis infections are asymptomatic and accordingly not aware of their infection, and this silent infection can subsequently result in severe reproductive tract complications and sequelae. The current review paper provides all background, evidence base and discussions for the 2015 European guideline on the management of Chlamydia trachomatis infections (Lanjouw E, et al. Int J STD AIDS 2015). Comprehensive information and recommendations are included regarding the diagnosis, treatment and prevention of anogenital, pharyngeal and conjunctival Chlamydia trachomatis infections in European countries. However, Chlamydia trachomatis also causes the eye infection trachoma, which is not a sexually transmitted infection. The 2015 European Chlamydia trachomatis guideline provides up-to-date guidance regarding broader indications for testing and treatment of Chlamydia trachomatis infections; clearer recommendation of using validated nucleic acid amplification tests only for diagnosis; advice on (repeated) Chlamydia trachomatis testing; recommendation of increased testing to reduce the incidence of pelvic inflammatory disease and prevent exposure to infection and recommendations to identify, verify and report Chlamydia trachomatis variants. Improvement of access to testing, test performance, diagnostics, antimicrobial treatment and follow-up of Chlamydia trachomatis patients are crucial to control its spread.

Abstract
BACKGROUND From 2003 to 2012, the Philadelphia High School STD Screening Program screened 126,053 students, identifying 8089 Chlamydia trachomatis (CT)/Neisseria gonorrhoeae (GC) infections. We examined sociodemographic and behavioral factors associated with CT/GC diagnoses among a sample of this high-risk population. METHODS Standardized interviews were given to infected students receiving in-school CT/GC treatment (2009-2012) and to uninfected students calling for results (2011-2012). Sex-stratified multivariable logistic models were created to examine factors independently associated with a CT/GC diagnosis. A simple risk index was developed using variables significant on multivariable analysis. RESULTS A total of 1489 positive and 318 negative students were interviewed. Independent factors associated with a GC/CT diagnosis among females were black race (adjusted odds ratio [AOR], 2.27; confidence interval, 1.12-4.58), history of arrest (AOR, 2.26; 1.22-4.21), higher partner number (AOR, 1.75; 1.05-2.91), meeting partners in own neighborhood (AOR, 1.92; 1.29-2.86), and meeting partners in venues other than own school, neighborhood, or through friends ("all other"; AOR, 9.44; 3.70-24.09). For males, factors included early sexual debut (AOR, 1.99; 1.21-3.26) and meeting partners at "all other" venues (AOR, 2.76; 1.2-6.4); meeting through friends was protective (AOR, 0.63; 0.41-0.96). Meeting partners at own school was protective for both sexes (males: AOR, 0.33; 0.20-0.55; females: AOR, 0.65; 0.44-0.96). CONCLUSIONS Although factors associated with a GC/CT infection differed between males and females in our sample, partner meeting place was associated with infection for both sexes. School-based screening programs could use this information to target high-risk students for effective interventions.

Abstract
Chlamydia trachomatis (CT) screening programs have been established in educational settings in many countries during the past 2 decades. However, recent evidence suggests that high uptake of screening and management (treatment, partner notification, and retesting for reinfection) improves program effectiveness. We conducted a systematic review to understand the screening strategies, the extent of screening conducted, and uptake of management strategies in educational settings. Screening studies in educational settings were identified through a systematic search of published literature from 2005 to 2011. We identified 27 studies describing 30 screening programs in the United States/Canada (n = 10), Europe (n = 8), Australia/New Zealand (n = 5), and Asia (n = 4). Most studies targeted both male and female students (74%). Classroom-based strategies resulted in 21,117 testes overall (4 programs), followed by opportunistic screening during routine health examination (n = 13,470; 5 programs) and opportunistic screening at school-based health centers (n = 13,006; 5 programs). The overall median CT positivity was 4.7% (range, 1.3%-18.1%). Only 5 programs reported treatment rates (median, 100%; range, 86%-100%), 1 partner notification rate (71%), 1 retesting rate within a year of an initial CT diagnosis (47%), and 2 reported repeat positivity rates (21.1% and 26.3%). In conclusion, this systematic review shows that a variety of strategies have been used to screen large numbers of students in educational settings; however, only a few studies have reported CT management outcomes.

Abstract
BACKGROUND This study examined the acceptability and feasibility of using a biological outcome measure to evaluate a school-based sexuality education program. Confidential field-delivered sexually transmitted infection (STI) testing by nonmedical field staff and STI treatment by medically trained field staff was assessed in off-campus and off-clinic settings for adolescents enrolled in the trial. METHODS After parental and adolescent consent were obtained, a convenient time and location was identified to collect urine to test for chlamydia (Chlamydia trachomatis, CT), gonorrhea (Neisseria gonorrheae, NG), and trichomonas (Trichomonas vaginalis, TV) infection and to treat students with positive results. RESULTS A total of 391 of 1742 students had permission to participate (22%); 353 (90%) provided urine samples; 28 (8%) had positive test results: CT(18), NG(5), and TV(8). Testing and treatment occurred at home for 92% and 59% of students, respectively; on weekdays (for 69% and 96%, respectively) and between noon and 8 pm (for 76% and 88%, respectively). All students who tested positive were treated. Several lessons and strategies that may improve the likelihood that students will participate in field-delivered STI testing and treatment emerged. CONCLUSION STI testing and treatment are feasible for students enrolled in a school-based sexuality education program. However, obtaining parental consent may be challenging.

Abstract
While laboratory aetiological diagnosis is considered the gold standard for diagnosis and management of sexually transmitted infections (STIs), syndromic management has been presented as a simplified and affordable approach for STI management in limited resource settings. STI signs and symptoms were collected using staff-administered computer-assisted personal interview and audio computer-assisted self-interview. Participants underwent a medical examination and laboratory testing for common STIs. The performance of syndromic management was assessed on the agreement between interviewing methods as well as accurate diagnosis. We screened 846 participants, of whom 88 (10.4%) received syndromic STI diagnosis while 272 (32.2%) received an aetiological diagnosis. Agreement between syndromic and aetiological diagnoses was very poor (overall kappa = 0.09). The most prevalent STI was herpes simplex virus type 2 and the percentage of persons with any STI was higher among women (48.6%) than men (15.6%, p < 0.0001). Agreement between audio computer-assisted self-interview and computer-assisted personal interview interviewing methods for syndromic diagnosis of STIs ranged from poor to good. Our findings suggest that syndromic management of STIs is not a sufficient tool for STI diagnosis in this setting; development and improvement of STI diagnostic capabilities through laboratory confirmation is needed in resource-limited settings.

Abstract
OBJECTIVE To describe the trends in chlamydia positivity among New Orleans high school students tested in a schoolwide screening between 1996 and 2005, and to determine factors associated with chlamydia positivity among students during the 10-year period. METHODS Between school years 1995-1996 and 2004-2005, students in New Orleans public high schools were tested for chlamydia using nucleic acid amplification tests (NAAT) in urine specimens (LCx assay until 1999-2000; BD assay from 2000-2001 to 2004-2005). For each year, we calculated chlamydia positivity by dividing the number of students testing positive by the total number of students tested. Data were analyzed separately by gender. Logistic regressions were performed to determine independent predictors of chlamydia positivity during the 10-year period. RESULTS Between 1996 and 2005, the average chlamydia positivity was 7.0% (95% confidence interval 6.6-7.4) in boys and 13.1% (95% confidence interval 12.6-13.7) in girls (P < .001). Chlamydia detection increased with the switch from LCx to BD assay. In multivariate analyses, chlamydia positivity among boys and girls was significantly associated with age, black race, and gonorrhea coinfection. Additionally, positivity was significantly different by school year among boys (P = .03) and by NAAT used among girls (P = .008). CONCLUSIONS The trends in chlamydia positivity observed between 1996 and 2005 more likely reflected a high and stable prevalence of chlamydia in the New Orleans school-age adolescent population. Any benefit of screening on individuals tested was likely to be mitigated by participants' uninterrupted social interactions with the dynamic forces that sustain the sexual transmission of chlamydia in the population.

Abstract
BACKGROUND This article describes a school-wide sexually transmitted infection (STI) screening to identify adolescent high-risk sexual behaviors, STI history/incidence, and presence of chlamydia and gonorrhea, and examines relationships between high-risk behaviors and screening positive for chlamydia and gonorrhea in an alternative high school setting. METHODS School-wide chlamydia and gonorrhea education and screening was provided to 869 adolescents; 226 males and 282 females 14-20 years (mean age = 17.07) consented to urine screening. Relationships were examined between screening positive, history of STIs, and high-risk sexual behaviors. RESULTS A majority (69%) of the adolescents consented to screening: 17.76% (92) had a history of STI; 8.83% (46) tested positive at screening. More females than males tested positive (p = .001). Significant relationships existed between history of STIs and ≥ 4 sexual partners (p = .0022), no condom use (p = .06), and sexual intercourse in last 3 months (p = .03). CONCLUSIONS School-Based Health Center (SBHC) screening was well accepted by students and staff. Sexually transmitted infection history was correlated with all identified high-risk sexual behaviors supporting the need for in-depth assessment, counseling, and testing of adolescents wherever they present for care. This study also provides an example of the role SBHCs can play in the national strategy to control chlamydia and gonorrhea in adolescents.

Abstract
BACKGROUND Adolescents are a risk group for acquiring sexually transmitted infections (STIs). In the Netherlands, senior vocational school students are particular at risk. However, STI test rates among adolescents are low and interventions that promote testing are scarce. To enhance voluntary STI testing, an intervention was designed and evaluated in senior vocational schools. The intervention combined classroom health education with sexual health services at the school site. The purpose of this study was to assess the combined and single effects on STI testing of health education and school-based sexual health services. METHODS In a cluster-randomized study the intervention was evaluated in 24 schools, using three experimental conditions: 1) health education, 2) sexual health services; 3) both components; and a control group. STI testing was assessed by self reported behavior and registrations at regional sexual health services. Follow-up measurements were performed at 1, 3, and 6-9 months. Of 1302 students present at baseline, 739 (57%) completed at least 1 follow-up measurement, of these students 472 (64%) were sexually experienced, and considered to be susceptible for the intervention. Multi-level analyses were conducted. To perform analyses according to the principle of intention-to-treat, missing observations at follow-up on the outcome measure were imputed with multiple imputation techniques. Results were compared with the complete cases analysis. RESULTS Sexually experienced students that received the combined intervention of health education and sexual health services reported more STI testing (29%) than students in the control group (4%) (OR = 4.3, p < 0.05). Test rates in the group that received education or sexual health services only were 5.7% and 19.9%, not reaching statistical significance in multilevel analyses. Female students were more often tested then male students: 21.5% versus 5.4%. The STI-prevalence in the study group was low with 1.4%. CONCLUSIONS Despite a low dose of intervention that was received by the students and a high attrition, we were able to show an intervention effect among sexually experienced students on STI testing. This study confirmed our hypothesis that offering health education to vocational students in combination with sexual health services at school sites is more effective in enhancing STI testing than offering services or education only.

Abstract
We examined the long-term effects of two interventions designed to reduce sexual risk behavior among African American adolescents. African American adolescents (N = 1383, ages 14-17) were recruited from community-based organizations over a period of 16 months in two northeastern and two southeastern mid-sized U.S. cities with high rates of sexually transmitted infection (STI). Participants were screened for three STIs (gonorrhea, chlamydia, and trichomoniasis) and completed an audio computer-assisted attitude, intention, and behavior self-interview. Youth who tested positive for an STI (8.3%) received treatment and risk reduction counseling. In addition, television and radio HIV-prevention messages were delivered during the recruitment period and 18 months of follow-up in one randomly selected city in each region. Analyses determined effects of the media program for those receiving a positive versus negative STI test result on number of sexual partners and occurrence of unprotected sex. Adolescents who tested STI-positive reduced their number of vaginal sex partners and the probability of unprotected sex over the first 6 months. However, in the absence of the mass media program, adolescents returned to their previously high levels of sexual risk behavior after 6 months. Adolescents who tested STI-positive and received the mass media program showed more stable reductions in unprotected sex. Community-based STI treatment and counseling can achieve significant, but short-lived reductions in sexual risk behavior among STI-positive youth. A culturally sensitive mass media program has the potential to achieve more stable reductions in sexual risk behavior and can help to optimize the effects of community-based STI screening.

Abstract
BACKGROUND Chlamydia trachomatis infection (CT) is the most prevalent bacterial STD. Sexually active adolescents and young adults are the main risk group for CT. However, STD testing rates in this group are low since exposed individuals may not feel at risk, owing-at least in part-to the infection's largely asymptomatic nature. Designing new testing environments that are more appealing to young people who are most at risk of acquiring chlamydia can be an important strategy to improve overall testing rates. Here we evaluate the effect of a school-based sexual health program conducted among vocational school students, aiming to obtain better access for counseling and enhance students' STD testing behavior. METHODS Adolescents (median age 19 years) attending a large vocational school were provided with sexual health education. Students filled in a questionnaire measuring CT risk and were offered STD testing. Using univariate and multivariate analysis, we assessed differences between men and women in STD-related risk behavior, sexual problems, CT testing behavior and determinants of CT testing behavior. RESULTS Of 345 participants, 70% were female. Of the 287 sexually active students, 75% were at high risk for CT; one third of women reported sexual problems. Of sexually active participants, 61% provided a self-administered specimen for STD testing. Independent determinants for testing included STD related symptoms and no condom use. All CT diagnoses were in the high-CT-risk group. In the high-risk group, STD testing showed an increased uptake, from 27% (previous self-reported test) to 65% (current test). CT prevalence was 5.7%. CONCLUSIONS Vocational school students are a target population for versatile sexual health prevention. When provided with CT testing facilities and education, self selection mechanisms seemed to increase CT testing rate dramatically in this high-CT-risk population expressing sexual problems. Considering the relative ease of testing and treating large numbers of young adults, offering tests at a vocational school is feasible in reaching adolescents for STD screening. Although cost-effectiveness remains an issue counseling is effective in increasing test rates.

Abstract
PURPOSE Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) are common sexually transmitted infections that disproportionately affect adolescents. Annual screening for CT for sexually active female adolescents is recommended. In 2006, New York City began conducting CT/GC education, screening, and treatment in public high schools. We examine 3-year programmatic outcomes and the relationship between sexual activity, screening, and CT/GC positivity. METHODS We describe the epidemiology of students who screened and those infected with CT/GC. Univariate, bivariate, and multivariate logistic regression analyses were performed to assess relationships between sex, race/ethnicity, age, sexual activity, and screening status; and the relationship between sexually transmitted infection positivity and sexual activity. RESULTS Between July 2006 and June 2009, we educated 57,418 students and screened 27,353 (47.6%) for CT/GC; 1,736 (6.3%) students were reported to be infected with either organism. Students who screened positive were more likely to be females (8.9%), report black race (8.3%) and be ≥16 years of age (6.6%-9.7%). Screening rates were 70.6% for students who were sexually active, 27.9% for those who had never had sex, and 47.3% for those who did not respond to the sexual activity question; CT/GC positivity was 7.2%, 1.4%, and 6.1%, respectively. CONCLUSIONS Black, older adolescent females were most likely to screen positive for CT/GC in this population. A large proportion of students who did not answer the sexual activity question chose to screen for CT/GC and screened positive. School screening programs should offer screening to all students regardless of reported sexual activity. Programs should target females and older adolescents.

Abstract
Background Poor awareness and knowledge of Chlamydia trachomatis could be a barrier to uptake of screening. This study aimed to determine the level of awareness and knowledge of chlamydia among young people who were being approached in a variety of community settings and offered opportunistic screening. Methods Men and women aged 16-24 years were approached in education, health and fitness, and workplace settings and invited to complete a self-administered questionnaire then provide a urine sample for chlamydia testing. Follow-up semi-structured interviews with 24 respondents were carried out after test results were received. Results 363 questionnaires were completed (43.5% from men). Whilst awareness of chlamydia was high, knowledge decreased as questions became increasingly focussed so that around half of respondents were unaware of the asymptomatic nature of chlamydia infections. Men's knowledge of symptoms was consistently lower than women's, with most men failing to identify unusual discharge as a symptom in men (men 58.3%, female 45.8%, p = 0.019); fewer men knew unusual discharge was a symptom among women (men 65.3% female 21.4%, p < 0.001). The asymptomatic nature of the infection resonated with respondents and was the commonest piece of information they picked up from their participation in the study. Conclusions Despite scientific gains in understanding chlamydia infection, public understanding remains limited. Greater efforts are required to translate scientific evidence to the public. An improvement in knowledge may maximise gains from interventions to improve detection.

Abstract
OBJECTIVES We implemented a chlamydia screening program targeted at young women accessing reproductive health care services in a school-based setting, and we assessed racial/ethnic factors associated with infection. METHODS The California Family Health Council partnered with 9 health care agencies receiving federal Title X family planning funding and 19 educational institutions to implement the Educational Partnerships to Increase Chlamydia Screening (EPICS) program from January 2008 through December 2008. RESULTS EPICS agencies provided reproductive health services to 3396 unique sexually active females, 85% of whom self-reported no other source for reproductive health care. Chlamydia screening was provided to 3026 clients (89.1% chlamydia screening coverage). Of those screened for chlamydia, 5.6% tested positive. Clients who were African American (odds ratio [OR]=7.5; 95% confidence interval [CI]=3.9, 14.3), Pacific Islander (OR=4.1; 95% CI=1.1, 15.5), or Asian (OR=3.3; 95% CI=1.4, 8.1) were more likely to have a positive test than were White clients. CONCLUSIONS Chlamydia screening programs implemented in school-based settings have the capacity to identify and treat a significant amount of asymptomatic infection in a population that otherwise may not be reached. To facilitate screening, school-based clinics should implement outreach strategies that target their school population and clinical strategies that maximize opportunities for screening.

Abstract
PURPOSE To examine the effect of a community-based sexually transmitted infection (STI) screening program on sexual risk behavior among African American adolescents. We hypothesized that adolescents testing positive for an STI and receiving post-test counseling would reduce risky sexual practices, whereas STI-negative adolescents would show little or no change in protective sexual behavior after screening. METHODS From August 2006 to January 2008, we recruited 636 sexually active African American adolescents (age, 14-17) from community-based organizations in two mid-sized U.S. cities with high STI prevalence. Participants were screened for three STIs (gonorrhea, chlamydia, and trichomoniasis) and completed an audio computer-assisted self-interview. Youth who tested positive for an STI (6.6%) received treatment and counseling. Youth testing negative received no further intervention. Approximately 85% of participants completed 3- and 6-month follow-up assessments. Generalized estimating equations determined the effects of STI screening on adolescents' number of sexual partners and occurrence of unprotected sex. RESULTS Adolescents who tested positive for an STI reduced their number of vaginal and oral sex partners and the probability of unprotected sex. STI-negative adolescents demonstrated no change for numbers of partners or unprotected sex. CONCLUSIONS Community-based STI screening can help to reduce sexual risk behavior in youth who test positive for STIs. Alternative approaches will be needed to reduce risk behavior in youth who test negative but who are nevertheless at risk for acquiring an STI.

Abstract
BACKGROUND Seeking screening and treatment for chlamydia (CT) and gonorrhea (GC) by young women is critical to reduction of asymptomatic cervicitis and its complications. OBJECTIVES To evaluate the efficacy of a client-centered motivational behavioral intervention (MBI), to promote seeking of sexually tranmitted infection (STI) checkups by young women. METHODS Three hundred seventy-six of 770 eligible sexually active, nonpregnant, English-speaking women (mean age 18.5 years) were recruited from an urban reproductive health clinic and randomized to two groups: intervention plus standard care (MBI) or standard care alone (SC). MBI (two sessions plus booster) was based on the Transtheoretical Model of Change and employed motivational interviewing. Outcome measures monitored for 12 months included: client-initiated clinic visits for STI checkups in response to seven high-risk sexual behaviors by self-report (primary), consistent condom use, number of CT and GC episodes, and movement along the stages of change obtained at baseline and 6- and 12-month follow-up assessments (secondary). Analyses included chi-square, logistic regression, and generalized estimating equations. RESULTS At baseline, more than 70% endorsed the action stage of change for seeking STI checkups for three of seven high-risk sexual behaviors. No significant differences were noted between the two groups for the primary or secondary outcomes. Across groups, having multiple partners and being pregnant or thinking one might be pregnant were associated with STI checkups. CONCLUSIONS This is the first known client-centered clinical trial to promote STI screening. Risk-taking and health-seeking behaviors are complex and interrelated with STI and pregnancy concerns. The intervention may have an effect if it is targeted to women in a less medically connected community-based sample.

Abstract
BACKGROUND The study was conducted to define the contact-tracing success rate of the partner notification services routinely provided by the community-based youth health centres and the county medical officer for communicable disease control (CMO) in Uppsala County, Sweden. OBJECTIVE The study had three goals, (i) to register the number of sexual partners routinely reported by each diagnosed index case with CT and the success rate in tracing and testing these partners for CT infection. (ii) To analyse the current notification practices in reporting the number of cases of unsuccessful contact tracing to the CMO. (iii) To determine the contact tracing success rate of the partner notification services provided by the CMO. METHODS Each diagnosed case of CT is obliged by law to participate in the contact-tracing procedure performed by the physician managing the patient or by a specialised sexually transmitted infection (STI) adviser. Successful contact-tracing is defined as the confirmed attendance of a sexual contact within 12 months of the contact with the index case. RESULTS The number of CT cases diagnosed by the youth health centres during the study period was 463 (299 females and 164 males). The females reported 660 male sexual contacts and the males reported 386 female contacts. Successful partner notification was achieved for 73% of all sexual contacts. 284 (190 females and 94 males) unsuccessful partner notifications were reported to the CMO of whom 98 (52%) of the female contacts and 20 (21%) of the male contacts were successfully notified by the CMO. However, for 134 (71 females and 63 males) partners, personal details given by the index case were insufficient for identification of the partner. CONCLUSIONS When asymptomatic, genital CT infection spreads among sexually active young adults with multiple, unidentified sexual partners, appropriate methods of partner notification are not sufficient to achieve its aims at the population level.

Abstract
The state of child and adolescent overall health in the United States evidences the need for both prevention and treatment. Although much time and energy has been spent in recent years discussing and improving health benefit coverage and affordability for children, physical access to services has not kept pace with these changes. This article will introduce four major physical health issues (obesity, diabetes, asthma, and teen pregnancy/STD) and five key mental health issues (suicide, depression, ADHD, aggression, and violence) facing young people today. In an effort to answer the question, "What can be done?" school-based health clinics and their impact on health and educational outcomes are examined.

Abstract
OBJECTIVES To evaluate the use of the Family Court System as a venue for screening adolescents, especially males for sexually transmitted diseases (STD). GOAL To identify, treat, and describe the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) infections among adolescents on probation under the jurisdiction of the Family Court System of Philadelphia from April 2004 through December 2006. STUDY DESIGN We analyzed data from the first several years of this program, which offered education and voluntary noninvasive screening for CT and GC to adolescents adjudicated delinquent and placed on probation through the Family Court of Philadelphia. RESULTS Between April 1, 2004 and December 31, 2006, 2270 adolescents were counseled about STDs, of whom 1605 voluntarily submitted a urine specimen for STD testing. Among the 1594 unique individuals with a valid test result, 13.9% (44 of 317) of females, 7.0% (90 of 1277) of males, and 8.4% overall (134 of 1594) were found to be positive for either or both STD. In total, treatment was confirmed for 93.3% (84/90) of males and 100% (44/44) of females testing positive. CONCLUSIONS Noninvasive STD testing was well accepted by adolescents in the Family Court System. Over several years of study, infection rates were found to be persistently high in both males and females. The Family Court is an effective venue to identify and treat adolescent males and females with chlamydia and/or gonorrhea infection.

Abstract
The cost-effectiveness of screening men for Chlamydia trachomatis depends in part on the prevalence of chlamydia in the screened population and the ease with which screening programs can be implemented. Screening in venues with high rates of chlamydia positivity among men may therefore be an important adjunct to chlamydia control. To evaluate the recent US literature on chlamydia positivity in chlamydia screening programs among asymptomatic men in nonsexually transmitted disease clinic settings, we reviewed published articles between 1995 and June 2007, using PubMed as the primary search tool. Articles were abstracted and positivity rates summarized by type of venue, race/ethnicity, age group, and US region. The overall median positivity rate was 5.1%. The highest rates were observed among men tested in juvenile (7.9%) and adult (6.8%) detention facilities, among blacks (6.7%), the 15 to 19 years old (6.1%) and 20 to 24 years old (6.5%) age groups, and among men screened in the southern United States (6.4%). Chlamydia rates among men are high in certain venues, particularly correctional settings, but also depend on the demographic composition of the target population and location. Programs considering male chlamydia screening programs should conduct pilot programs to assess chlamydia positivity as well as feasibility and cost in target venues.

Abstract
A community-based intervention, Focus-on-Kids (FOK) has demonstrated risk-behaviour reduction of urban youth. We modified FOK to Focus-on-Teens (FOT) for high schools. High school adolescents (n=1190) were enrolled over successive school semesters. The small-group sessions were presented during the school-lunch hours. Confidential surveys were conducted at baseline, immediate, six-, and 12-month postintervention for demographics, parental communication/monitoring, sexual risk behaviours and sexually transmitted diseases (STDs)/HIV/condom-usage knowledge. Sexually active participants were encouraged to volunteer for urine-based STDs testing at the School-Based Health Centres. Many (47.4%) students reported having had sexual intercourse at baseline. Overall behaviours changed towards 'safer' sex behaviours (intent-to-use and using condoms, communicating with partner/parents about sex/condoms/STDs) with time (P<0.05). Proportion of students with complete correct knowledge of STDs/HIV increased to 88% at time 4 from 80% at baseline after adjusting for age, gender and sexual activity (P<0.05). High prevalence of STDs was detected in 875 participants who reported for urine testing at time 1: trichomonas, 11.8%; chlamydia, 10.1% and gonorrhoea, 4.1%. Prevalence decreased significantly for 310 participants who re-tested; chlamydia: 27.4% to 6.1% and gonorrhoea: 11.3% to 3.2%. FOT was successfully implemented as an STDs/HIV risk-reduction intervention. Sustained improvements of knowledge about STDs/HIV/condom usage, decreases in sexual risk behaviours supported the effectiveness of this intervention.

Abstract
BACKGROUND Urine-based screening for Chlamydia trachomatis using highly sensitive and specific nucleic acid amplification tests offers a unique opportunity to screen men attending school-based health centers. METHODS As part of a large multicenter chlamydia screening project in men, 1434 students were enrolled; 1090 in high schools in Baltimore and 344 middle and high-school students in Denver. Students were screened for chlamydia using urine-based nucleic acid amplification tests at well adolescent visits, acute care visits, or visits for other reasons, such as sports physicals. A self-administered survey to ascertain sexual risk behaviors was used. Data were analyzed separately for Baltimore and Denver, with univariate and multivariate logistic regression analysis. RESULTS The overall prevalence in asymptomatic adolescent men was 6.8% (7.5% in Baltimore and 4.7% in Denver, P = n.s.). Students in Denver were older, more racially diverse, and more likely to have had intercourse in the previous 2 months than students in Baltimore. Students in Baltimore were more likely than those in Denver to have used a condom at last intercourse with casual and main partners. Among men in Denver but not Baltimore, condom use at last intercourse with both casual (OR 0.15, 95% CI, 0.03, 0.78) and main partners (OR 0.30, 95% CI, 0.10, 0.91) was protective against infection. The only risk factor for CT infection in Baltimore students was age (OR 1.47, 95% CI, 1.23, 1.75). In multivariate analysis that included age (as a continuous variable), race, history of an STI, any sex partner in the last 2 months, >1 sex partner in the past 12 months, a new partner in the last 2 months, and condom use with last main and last casual partner, age (adjusted odds ratio 1.34, 95% CI, 1.11, 1.62) and black race (adjusted odds ratio 2.37, 95% CI, 1.21, 4.63) were the only variables associated with testing chlamydia positive. CONCLUSIONS School-based health centers are important venues in which to perform urine-based screening for chlamydia in sexually active, asymptomatic males, especially in high prevalence communities, and such screening provides the opportunity to identify and treat substantial numbers of chlamydia infections.

Abstract
Research in pediatric pharmacology has undergone major changes in the last ten years, with an expansion in both publicly and privately funded activities. A number of pharmacokinetics studies and multi-site controlled efficacy trials have been conducted, so that treatment of children and adolescents can now be better informed and evidence-based. Regulatory financial incentives to industry in return for studies on drugs still covered by patent exclusivity have resulted in a substantial increase in pediatric research funded by pharmaceutical companies. In parallel, public funding has supported research on off-patent medications and other clinical important aspects of treatment, such as comparisons between active treatments, including non-pharmacological interventions. With greater interest by industry in pediatric research, the role of government funding agencies has been redefined to avoid duplication and ensure better integration of efforts and utilization of resources. The present review discusses some of the recent developments in pediatric pharmacology with focus on psychiatric medications.

Abstract
OBJECTIVES Chlamydia prevalence varies regionally but is highest in the South, which could be the result of regional differences in testing behavior. We describe the national and regional prevalence of self-reported chlamydial infection (Ct) testing and examine how financial resources might be associated with Ct testing. METHODS We conducted a cross-sectional analysis of data from 12,334 sexually experienced young adults who participated in wave III of the National Longitudinal Study of Adolescent Health (2001-2002). We estimated the prevalence of Ct testing by region and gender, and calculated prevalence odds ratios for the relationship between income or insurance status and Ct testing. RESULTS Among women, Ct testing in the past year was low (27.3%; 95% CI, 25.5-29.2) and lowest in the South (24.8%). Compared with publicly insured females, privately insured (OR, 0.72; 95% CI, 0.57-0.92) and uninsured females (OR, 0.63; 95% CI, 0.48-0.88) were less likely to report testing. Young women with low income were more likely to report testing than those with a higher income (OR, 1.36; 95% CI, 1.12-1.66). Men reported similar testing patterns. CONCLUSIONS The South has the highest chlamydia prevalence and the lowest levels of Ct testing in the United States. Reducing infection prevalence and regional disparities in the burden of this infection requires region-focused funding and innovative strategies to increase testing and treatment programs.

Abstract
OBJECTIVES A self-test screening program for genital C. trachomatis infection in female students attending high school in rural Nova Scotia was introduced. The objectives of this pilot study were to determine the extent of uptake, reasons for being/not being screened, and whether students at risk would be more likely to be screened. METHODS The screening program was carried out between September 2005 and May 2006. Test kits were accessed through the school's health centre without first seeing the school nurse for counselling. Tests were processed non-nominally at the laboratory. A cross-sectional survey was offered to all students in the school to assess factors related to participation or non-participation. Univariate analysis was carried out for young women's sexual activity and risk taking, reasons for being participants or non-participants, risk behaviours, and knowledge about chlamydia. RESULTS One hundred and sixty-three women (58%) had had vaginal intercourse at least once. Twenty-four of these used the self-test kit. Though 83% of those not using the self-test knew that females with chlamydia are very often asymptomatic, 54% indicated lack of symptoms as a reason for not doing so. Many (49%) gave low probability of infection as a reason for not using the kit, but high-risk sexual activity was frequent in these young DISCUSSION Uptake of self-testing for C. trachomatis was lower than anticipated. This may be due to lack of counselling meant to encourage testing to overcome a dissonance of knowledge and behaviour. Self-testing should be further explored to better understand its potential to increase chlamydia screening among Canadian adolescents.

Abstract
BACKGROUND Chlamydia trachomatis (CT) infections are common among adolescents attending high and middle schools. The study objective was to determine the reinfection rates of CT for females attending school-based health centers. METHODS Adolescents attending school-based health centers who reported they were sexually active were screened for CT using nucleic acid amplification tests on cervical or urine samples. Between 1996 and 2003, 10,609 female students were tested. The overall annual prevalence for unduplicated students in a calendar year ranged from 15.1% to 19.5%. Reinfection was defined as a positive test result occurring between 30 and 365 days after an initial positive result. RESULTS There were 897 female students who tested positive for CT and returned for at least 1 subsequent test between 30 and 365 days later. Of these, 236 had 1 or more subsequent positive tests for a cumulative incidence of reinfection in 1 year of 26.3% (95% confidence interval = 23.4-29.2%). Young age at first infection was significantly associated with increased risk of subsequent infection (P <0.01). Across sites, the cumulative incidence of reinfection in these female students ranged from 14.3% to 38.9%. CONCLUSIONS The chlamydia cumulative incidence of reinfection in these female adolescents attending high and middle schools was high and supports the Centers for Disease Control and Prevention recommendation to screen adolescents frequently, especially those with a history of a previous chlamydia infection.

Abstract
PURPOSE Assess the feasibility of offering and barriers to accepting urine-based screening for Chlamydia trachomatis (CT) among asymptomatic adolescent mothers during their children's health care visits. METHOD Providers were automatically cued to offer CT-screening to 13 through 21 year old mothers when they opened the child's medical record. Recording the mothers' screening decisions removed the flag for 6 months. Providers were also prompted to assess the perceived importance of CT prevention, likelihood of having CT, and the worst aspect of having CT. RESULTS Mothers usually brought their children to the clinic. Hence, providers could act on 97% of the 318 flags they saw. They responded appropriately 75% of the time. Only 96 (42%) of the 229 mothers who were asked agreed to screening. The primary reasons for declining were "monogamous" and "tested within 6 months". Almost everyone said CT was a top preventive health priority, but that they would be surprised if they were infected. Mothers who agreed to screening were less likely to have a child less than 6 months of age (26.0% vs. 57.1%; P < 0.0001). They were also more likely to rate knowledge of partner infidelity (39.4% vs. 13.6%; P = 0.03) and less likely to rate medical problems (15.2% vs. 40.9%; P = 0.01) the worst aspect of having CT. None of the 21 urine samples obtained within 6 months of delivery were positive for CT. Thereafter, 5 (9.1%) of the 55 urines were positive. CONCLUSIONS It is feasible and useful to screen adolescent mothers for CT at their children's health care visits. The best way to increase the efficacy and strengthen the impact of urine-based CT-screening in this setting is to initiate testing after the 6th postpartum month and heighten awareness of STD-risk among adolescent mothers.

Abstract
Knowledge of drug administration in children and infants has significantly lagged behind that of adults. Despite several paediatric therapeutic mishaps that have been a catalyst for major regulatory reform, the majority of registered medicines do not have indications or dosing for children. This paper will briefly summarise key issues in paediatric pharmacology, including differences in prescribing for children, off-label and unlicensed prescribing and conduct of paediatric clinical trials. A particular emphasis will placed on the situation in Australia.

Abstract
RATIONALE Research in pediatric psychopharmacology has expanded considerably in the last 10 years. Still, controversy remains about the effectiveness and safety of commonly used psychotropics and their role in child treatment, thus pointing to the need for more in-depth and targeted investigations. OBJECTIVES To review recent accomplishments and current limitations of pediatric psychopharmacology, and discuss approaches to further research. METHODS Selective review of the relevant literature and research in progress. RESULTS Controlled clinical trials have been conducted in many common psychiatric disorders in children and adolescents, thus providing a basis on which evidence-based treatment guidelines can be constructed. Little innovation has, however, occurred in treatment development and testing. Safety concerns are prominent and have a major influence on clinical practice and drug utilization. CONCLUSIONS While a research infrastructure has been successfully built for conducting pediatric clinical trials, important aspects such as long-term treatment effects, optimal sequencing and individualization of interventions, and integration of neuroscience findings into innovative, theory-driven treatment development remain to be addressed.

Abstract
OBJECTIVE To prospectively study the relationship between diagnosis of sexually transmitted infections (STIs) at entry to U.S. Marines recruit training and subsequent sexual behaviors during vacation. METHODS Of all women entering recruit training (June 1999-June 2000), 2,157 (94%) voluntarily enrolled. At baseline, women received universal screening for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis and treatment and counseling for positive STIs. Recruit training (13 weeks) precluded any social activities. Unrestricted vacation followed (median 10 days). After training resumed (3 weeks), questionnaires and repeat STI screening were administered. Multivariable logistic regression examined STI diagnosis at baseline as a predictor for risky sexual behaviors at vacation and STI-positive diagnosis after vacation. RESULTS The study was completed by 1,712 (79%) women (median age 18 years); 1,038 reported sexual activity during vacation; 71% used condoms inconsistently; 19% had casual partners. At baseline, 152 (15%) tested STI-positive. Baseline STI diagnosis was unrelated to inconsistent condom use, nonmonogamous partnerships, or multiple partnerships. However, women testing STI-positive at baseline were more likely to test STI-positive after vacation (adjusted odds ratio 3.74, 95% confidence interval 2.10-6.65). Baseline STI diagnosis predicted casual partnerships among women aged 19-21 years (adjusted odds ratio 2.48, 95% confidence interval 1.12-5.50). CONCLUSION Substantial numbers of women engaged in risky sexual behaviors after universal STI screening and counseling. Compared with STI-negative women, STI-positive women were at increased risk for subsequent STI acquisition regardless of their similar behaviors. As universal STI screening is increasingly implemented, follow-up care will likely be required to further reduce risky behaviors and address network-level factors. LEVEL OF EVIDENCE II.

Abstract
OBJECTIVE The purpose of the study was to assess the extent to which students are screened for sexually transmitted diseases (STDs) in their school-based health centers (SBHCs) in a Louisiana school district. GOAL The goal of this study was to determine the proportion of students who reported having been tested or treated for STDs at their SBHCs in the past 3 months and the prevalence of chlamydia and gonorrhea among respondents. STUDY DESIGN During the 2002-2003 and 2003-2004 school years, 487 students registered in their SBHCs, and who visited routinely their SBHC at least once in the past 3 months, participated in a chlamydia and gonorrhea screening independent of services their SBHCs provide. Participants were asked whether in the past 90 days they had been tested or treated for an STD at their SBHC. RESULTS Among respondents, 47/482 (9.8%) reported having been tested or treated for an STD at the SBHC in the previous 3 months. Overall, 65/487 (13.3%) tested positive for chlamydia or gonorrhea. Of the 65 students who tested positive, 53 (81.5%) were not tested or treated for an STD at the SBHC. CONCLUSIONS Many infections could have been detected by testing students during routine visits in SBHCs. Lack of routine screening in these SBHCs clearly represents missed opportunities for early detection of chlamydia and gonorrhea among local teens.

Abstract
We reviewed literature on gonorrhea prevention and clinical care in the private sector, the setting where most gonorrhea cases in the United States are now diagnosed. Although most private-sector health settings had a low prevalence of gonorrhea (0.1-2.5%), some private emergency departments and specialty clinics that serve a large number of high-risk or infected patients had prevalences ranged from 1.7% to 11.0%. Studies of diverse settings and populations suggest that, in general, diagnostic testing of symptomatic patients (69-83%), appropriate treatment (61-100%), and case reporting (64-94%) are delivered more commonly than risk assessment for asymptomatic patients (15-28%), routine screening of pregnant women (31-77%), risk-reduction counseling (35-78%), and sex partner management (0-82%). To sustain the recent declines in gonorrhea incidence in the United States, private-sector providers and health systems must continue to offer gonorrhea prevention and clinical services and consider implementing interventions to improve delivery of risk assessment, risk-reduction counseling, and partner management services.

Abstract
CONTEXT The prevalence of sexually transmitted diseases among adolescents is high. Innovative screening and treatment programs need evaluation. OBJECTIVES The objectives of this study were to identify, treat, and describe the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) infections among Philadelphia public high school students. DESIGN We analyzed cross-sectional data from the first year of an annual program offering education, screening, and treatment for CT and GC. For the school year analyzed, screening took place between January 2003 and June 2003. RESULTS In the first year, 19,394 students aged 12-20 years were voluntarily tested; 1,052 students were identified with GC, CT, or both; 1,051 received treatment. Prevalence of CT among females (95% confidence interval [CI] = 8.1) was 3.3 times higher than among males (95% CI = 2.5%). Attending disciplinary schools and residing in high reported morbidity areas were also related to higher prevalence of CT and GC. CONCLUSIONS A high prevalence of CT infections was identified among Philadelphia public high school students. This program demonstrated the effectiveness of a school-based screening program to identify and treat these infections.

Abstract
The sexually transmitted infection (STI) epidemic among adolescents in the USA is inextricably tied to individual, psychosocial and cultural phenomena. Reconceptualizing the epidemic within an expanded socio-ecological framework may provide an opportunity to better confront its challenges. In this article, we use a socio-ecological framework to identify determinants of adolescents' sexual risk and protective behaviours as well as antecedents of their STI acquisition. The goal is to provide a synthesis of several discrete categories of research. Subsequently, we propose an integrated strategy that addresses the STI epidemic among adolescents by promoting a socio-ecological perspective in both basic research and intervention design. This approach may expand the knowledge base and facilitate the development of a broader array of intervention strategies, such as community-level interventions, policy initiatives, institutionally based programmes, and macro-level societal changes. Although there are inherent challenges associated with such an approach, the end result may have reciprocal and reinforcing effects designed to enhance the adoption and maintenance of STI-preventive practices among adolescents, and further reduce the rate of STIs.

Abstract
OBJECTIVES The rate of tubo-ovarian abscess (TOA) in adolescents with pelvic inflammatory disease (PID) is reported to range from 17% to 20%. However, no reports have focused specifically on the adolescent patient presenting to the emergency department (ED), regardless of whether they are treated in the inpatient or outpatient setting. Recent changes in the 2002 Centers for Disease Control and Prevention (CDC) Guidelines for the Treatment of Sexually Transmitted Diseases and sexually transmitted infection screening programs are likely to have impacted both the prevalence of PID and the rates of its complications, particularly TOA. Given that most patients with PID are treated as outpatients, it is imperative to accurately assess the prevalence of TOA in this population. Therefore, we sought to determine the rate of TOA in female adolescents diagnosed with PID in a large urban pediatric ED. METHODS We performed a retrospective medical record review to assess the prevalence of TOA in adolescents diagnosed with PID in the ED by an attending physician in pediatric emergency medicine. All cases were identified on the basis of the clinical criteria from the 2002 CDC Guidelines for the Treatment of Sexually Transmitted Diseases. Data collected included historical and physical examination findings, and laboratory and radiological imaging results. RESULTS Three (2.4%; 95% confidence interval, 0.5-6.7) of 127 patients diagnosed with PID in the ED who had imaging or clinical follow-up were also found to have a TOA. The mean age of the patients was 16 years. Most patients (89%) had imaging studies performed within 24 hours; most of these studies (97%) were pelvic ultrasounds. Eleven patients did not have imaging but had clinical follow-up within 72 hours. Four patients were diagnosed with PID during the study period and were lost to follow-up. CONCLUSION The rate of TOA in adolescents diagnosed with PID in an urban pediatric ED is much lower than the rates previously reported in adolescents. This lower prevalence may be attributed to the broader 2002 CDC guidelines for diagnosing PID. In addition, community-based screening programs for Chlamydia trachomatis and Neisseria gonorrhoeae may help to identify young women at risk for developing PID earlier in the course of infection.

Abstract
BACKGROUND/OBJECTIVES Testing for Chlamydia trachomatis (Ct) is less accepted in people of non-Dutch ethnicity than Dutch people. We offered additional Ct and gonorrhoea testing through our outreach sexually transmitted infections (STI) prevention programme to determine whether this intervention strategy is feasible and efficient. METHODS Outreach workers offered test kits to women and men aged 15-29 years, in group and street settings and in a vocational training school. Demographic and behavioural data and characteristics of non-responders were assessed. DNA was isolated (using the MagNA Pure LC system) from urine and tested using the Cobas Amplicor test. RESULTS Among sexually active people, the test rate differed by venue (groups 80% (74/93), school 73% (49/67), street 17% (49/287); p<0.001). There was no difference in test rate between group and school settings by gender or ethnicity. Ct positivity was 14.5% (25/172); women 20.2% (20/99) versus men 6.8% (5/73); p = 0.01. Ct positivity was highest at school (24.5% (12/49)) and among Surinamese/Antillean people (17.5% (14/80)). Treatment rate of index cases and current partners was 100% and 78%, respectively. CONCLUSIONS We found a high acceptance of chlamydia testing in group and school settings in both men and women of non-Dutch ethnicity. The prevalence indicates that we have accessed high risk people. Outreach testing and is feasible and most efficient in school and group settings. School screening may have an impact on community prevalence of Ct infections.

Abstract
The objectives were to study: (1) acceptance of STD screening in non-clinical settings for asymptomatic individuals; (2) risk factors and STD prevalence among individuals in non-clinical and clinical settings; and (3) non-clinical screening of asymptomatic populations as a feasible method for STD control. We recruited 139 males and 486 females between 18 and 30 years of age from a family planning clinic, schools, and community centers in low-income neighborhoods. We asked about STD symptoms and STD/HIV risk behaviors and tested the individuals for gonorrhea, Chlamydia, syphilis, and HIV. Except for HIV, women recruited directly from the community had higher STD rates than those who came in for care at the clinic. Screening in non-clinical settings in Brazil is feasible and has a high yield among young adults in low-income communities. Infected participants would likely never have otherwise sought care or been tested or treated. STD control efforts could be implemented in any site that can reach populations at risk and become a routine procedure in health care settings where people report for problems unrelated to STDs.

Abstract
This paper provides a discussion of the utility of stigma theory as a conceptual framework for the interpretation and analysis of the psychological impact of contracting a sexually transmissible infection (STI). Most particularly, it focuses on those viral infections that cannot be medically cured, such as genital herpes and genital human papilloma virus. Recent research in the area of STIs suggests that the stigma associated with these conditions can hinder psychosocial and sexual adjustment post-diagnosis, and provides support for the use of stigma theory as a conceptual framework with which to analyse these experiences. This paper defines the concept of stigma and presents a theoretical overview of the process of stigmatisation. Three dimensions of stigma relevant to the experience of having a STI are then presented: the degree of concealability of the condition including the social consequences of concealing a condition; the origin of the condition; and the degree of peril presented by the condition. An overview of the way in which the presence of a stigmatising condition such as a STI may affect a person's feelings of self and his/her intimate relationships is then presented. Finally, the implications of stigma theory as a conceptual framework for guiding future research in the area of personal and interpersonal reactions to STIs is discussed.

Abstract
This article addresses the epidemiology of several common sexually transmitted infections (STIs) in adolescents. Chlamydia is a common occurrence in adolescents, more so than is gonorrhea, but both are of particular concern because they may cause pelvic inflammatory disease. Many experts recommend screening for chlamydia in sexually active adolescents, particularly females. Trichomonas vaginalis is significant as a marker for risk of contracting other STIs and because of its association with pregnancy complications and with increased risk of transmission of HIV. Genital herpes simplex virus (HSV) infection, which usually has been caused by HSV-2, is a common finding in adolescents, and it now is caused also by HSV-1 in some populations. Human papillomavirus (HPV), though widespread in adolescents, usually is a self-limited infection, and malignancy resulting from HPV is a rare occurrence in this age group. The least common of the diseases discussed below is syphilis, but a recent sharp increase in incidence has occurred in men who have sex with men.
