Prevalence and Factors Associated With Mycoplasma genitalium Infection in At-Risk Female Adolescents in Bronx County, New York.

BACKGROUND: Mycoplasma genitalium infection can adversely affect female reproductive health, but data are limited about prevalence and characteristics of the infection in female adolescents. We employed a sensitive assay to detect M. genitalium infection, and we describe its characteristics in a clinical sample of women younger than 21 years. METHODS: We recruited females aged 13 to 20 years in children's hospital clinics whose clinicians were testing for chlamydia/gonorrhea. Participants completed a questionnaire providing demographics, sexual history, and current symptoms. Urine/endocervical samples were tested for chlamydia/gonorrhea and partitioned for M. genitalium testing using Aptima M. genitalium assay. We reviewed records for the clinic visit to document examination, diagnosis, and results of sexually transmitted infection (STI) testing. We compared prevalence of M. genitalium infection by demographics, sexual history, symptoms, and signs. RESULTS: Of 153 participants mean age 18.07 ± 1.68 years, 58% self-identified as Hispanic, 27% Black, 64% straight/heterosexual, 27% bisexual, 1% gay/lesbian, 29% reported a prior STI diagnosis. Prevalence of M. genitalium was 11.1% (17/153), 13 of 17 were asymptomatic, 2 of 17 had pelvic inflammatory disease (PID), 3 of 17 coinfected with chlamydia or gonorrhea. Prevalence of chlamydia was 6.6% and of gonorrhea 2.6%. A logistic regression model indicated independent associations of bisexual orientation versus all other orientations (adjusted odds ratio [aOR], 4.80; 95% confidence interval [CI], 1.38-16.67), self-reported prior STI (aOR, 3.83; 95% CI, 1.10-13.37), and self-reported prior PID (aOR, 9.12; 95% CI, 1.02-81.72) with higher odds of M. genitalium infection. CONCLUSIONS: Findings suggest that in at-risk female populations younger than 21 years, M. genitalium is a prevalent STI and symptomatic adolescents may warrant testing and treatment. Further study of harms and benefits of testing asymptomatic bisexual female adolescents or those with prior STI/PID is needed.

Reproductive Health Care for Female Adolescents Prescribed Mycophenolate at a Children's Hospital: A 10-Year Retrospective Cohort Study.

OBJECTIVES: To describe female adolescents' reproductive health needs and subspecialists' teratogenic counseling at initiation of mycophenolate as well as use of reproductive health care and contraception after mycophenolate initiation. STUDY DESIGN: We searched health records for female patients aged 12-20 years prescribed mycophenolate from 2010 to 2019. We included 125 subjects, 72 with systemic lupus erythematosus, 27 with transplants, and 26 with other conditions. We reviewed all encounters with pediatric subspecialists and reproductive clinicians. We recorded counseling by subspecialists at mycophenolate initiation and compared rates pre- and post-Risk Evaluation and Mitigation Strategy (REMS). We recorded subjects' menstrual, sexual and pregnancy history, type of first highly effective contraceptive method used, and duration of use over the decade. RESULTS: At mycophenolate initiation, mean age was 16.8 ± 2.6 years; 72% Hispanic/Latina or Black. In total, 80% were postmenarchal, 28% ever had sex, 18% ever had a reproductive health care visit, 14% used highly effective contraception, and 7% were ever pregnant. Post-REMS vs pre-REMS, we found greater rates of counseling for teratogenicity (68% vs 32%, P < .001) and contraception (62% vs 32%, P < .001) and pregnancy testing (51% vs 24%, P < .01). Over the mean 4.9 ± 3.3 years' follow-up, 56% ever had sex; 59% ever attended a reproductive health care visit; 38% used highly effective contraception; and 10% had a pregnancy. CONCLUSIONS: Adolescents prescribed mycophenolate have ongoing unmet reproductive health care needs. Although many are sexually active, fewer use effective contraception. Teratogenicity counseling rates improved over the decade but not rates of referral for reproductive health care.

Does Obesity Influence Body Mass Index Changes in Nulliparous Adolescent Users of Long-Acting Reversible Contraceptives?

OBJECTIVES: To compare body mass index (BMI) changes in adolescents using long-acting reversible contraceptives (LARCs), specifically, the etonogestrel subdermal implant (ENG-implant), levonorgestrel intrauterine device (LNG-IUD), and copper IUD (Cu-IUD), by initial BMI category from the time of LARC insertion to within 6-18 months after insertion. DESIGN: This was a single-center retrospective cohort study. SETTING AND PARTICIPANTS: We reviewed electronic health records from our large health system to identify and follow a cohort of 196 adolescents aged 14-19 years with LARCs inserted from 2010 to 2016. We excluded adolescents with conditions or medications affecting weight, including childbirth. MAIN OUTCOME MEASURE: BMI change from LARC insertion to first BMI documented after 6-18 months RESULTS: Mean age was 17.2 ± 0.2 years; 59% of the cohort was Hispanic and 29% Black. Mean BMI was 26.4 ± 7.1 kg/m2. Of the total cohort of adolescents, 51% were underweight/normal, 24% overweight, and 25% obese. Mean time to first BMI documented after LARC insertion was 10.1 ± 3.2 months. Mean BMI change for the total cohort was +0.73 ± 1.8 kg/m2, indicating weight gain. Mean BMI change for the ENG-implant + LNG-IUD users (n = 127) was larger than for Cu-IUD users (n = 69) (+0.92 ± 1.9 kg/m2 vs +0.37 ± 1.6 kg/m2, respectively, P < .05). Two-way analysis of variance showed that both initial BMI category (P = .001) and type of LARC (P = .011) had an independent significant main effect on BMI change. A significant interaction effect (P = .017) showed that obese adolescents had a larger increase in BMI when they were using a progestin-releasing LARC, either ENG-implant or LNG-IUD, as compared to a Cu-IUD (P < .05). CONCLUSION: Adolescents using progestin-releasing LARCs had a larger increase in BMI within 6-18 months after device insertion than those using Cu-IUDs. The disproportionate increase in BMI with progestin-releasing LARCs was primarily contributed by obese users.

Pediatricians as Child Health Advocates: The Role of Advocacy Education.

In this article, we discuss the role of formal advocacy education with high-effort advocacy activities among pediatricians. We discuss the historical role of advocacy in the field of pediatrics and the changing role of advocacy education in pediatric training programs. We describe our survey of pediatricians in New York, in which we asked about a history of formal child health advocacy education, current high- and low-effort advocacy activities, perceived barriers to advocacy work, and child health advocacy issues of interest. Our findings demonstrate an association between a history of formal child health advocacy education and recent participation in high-effort advocacy activities on behalf of children's health. We also found that practicing pediatricians were more likely to participate in high-effort advocacy work than individuals still in pediatric residency training. Our findings imply that education in child health advocacy should be considered an important part of pediatric training. Advocacy education should not only be included in residency and fellowship training programs but also made available as part of continuing medical education for pediatricians. Time for professional advocacy work should be allotted and encouraged.

Fertility Desires of Adolescent Females: Decreased Desire for Children in Those Identifying as Transgender/Gender Diverse and in Depressed Adolescents.

STUDY OBJECTIVE: We aimed to describe fertility desires in healthy adolescent females and to explore associations of fertility desire with conditions and therapies potentially compromising fertility. DESIGN: This was a cross-sectional, anonymous survey. SETTING AND PARTICIPANTS: A total of 323 female adolescents aged 13-19 years were recruited from clinic waiting areas at a children's hospital. We oversampled on days when clinics serving adolescents with potential fertility compromise were scheduled. MAIN OUTCOME MEASURES: We measured fertility desire by agreement with the statement "I want to have children someday." To measure compromised fertility we asked "In the past year, has a doctor, nurse or other medical professional ever talked to you about the possibility that you may have decreased fertility and may not be able to have your own biological child someday?" To measure depression severity, we used a validated scale, the PHQ-9, scores were dichotomized into no/mild and moderate/severe depression. RESULTS: Mean age was 16.06 ± 1.87 years. Of the 323 participants, 57% identified as Hispanic, 24% as Black, 93.5% as cisgender, 6.5% as transgender/gender diverse, 70% as heterosexual, and 30% as sexual minority. A total of 35% had moderate/severe depression, and 12% had compromised fertility. Overall, 89% wanted children. Fewer transgender/gender diverse than cisgender participants wanted children (67% vs 93%, P < .001), as did fewer with moderate/severe versus no/mild depression (83% vs 93%, P < .05), whereas those with compromised fertility versus those without and heterosexual versus sexual minority participants had similar fertility desires. Transgender/gender diverse identity (odds ratio, 0.33; 95% confidence interval, 0.11-0.97; P < .05) and moderate/severe depression (odds ratio, 0.45; 95% confidence interval, 0.22-0.93; P < .05) were independently associated with lower fertility desire. CONCLUSIONS: We found a high overall proportion of female adolescents desiring future children, and only 2 independent predictors of decreased fertility desire, namely, transgender/gender diverse identity and moderate/severe depression.

Sexting and Young Adolescents: Associations with Sexual Abuse and Intimate Partner Violence.

STUDY OBJECTIVE: To explore whether sexting by young adolescent girls and boys is associated with adverse life experiences including exploitative or violent sexual relationships. DESIGN AND SETTING: Cross-sectional, anonymous survey of a convenience sample of minor adolescents younger than age 18 years recruited while waiting for care in clinics affiliated with a children's hospital in a low-resource, high-poverty, urban community. PARTICIPANTS: Five hundred fifty-five adolescents aged 14-17 years, 63% girls and 37% boys. MAIN OUTCOME MEASURES: We measured sexting by asking, "Have you ever sent a sexually suggestive or naked picture of yourself to another person through text or e-mail?" The survey also measured risk behaviors, sexual abuse, intimate partner violence (IPV), and arrest and included a validated depression scale. RESULTS: Mean age was 15.6 ± 1.1 years; 59% were Hispanic, 28% were black; 44% of girls and 46% of boys ever had sex; 24% of girls and 20% of boys ever sent a sext. More girls than boys reported sexual abuse (16% vs 3%; P < .01), IPV victimization (15% vs 7%; P < .01), and depression (33% vs 17%; P < .01). More boys than girls reported arrest (15% vs 7%; P < .01). Independent associations with sexting for girls were: ever had sex (odds ratio [OR], 4.59; 95% confidence interval [CI], 2.29-9.19; P < .001); sexual abuse (OR, 3.81; 95% CI, 1.80-8.05; P < .001); IPV victim (OR, 2.72; 95% CI, 1.11-6.62; P < .05), and for boys: ever had sex (OR, 4.26; 95% CI, 1.47-12.32; P < .01); sexual abuse (OR, 38.48; 95% CI, 1.48-999.46; P < .05); IPV perpetration (OR, 16.73; 95% CI, 1.64-170.75; 95% CI, P < .05), as well as cannabis use, older age, other race, and arrest. CONCLUSION: For young adolescents, sexting is independently associated with exploitative and abusive sexual relationships including sexual abuse and IPV with similarities and differences in predictors of sexting for girls and boys.

The Female Athlete Triad: A Comparison of Knowledge and Risk in Adolescent and Young Adult Figure Skaters, Dancers, and Runners.

STUDY OBJECTIVE: The female athlete triad is often found in sports that value leanness and aesthetics and can lead to adverse health effects. We aimed to compare knowledge and risk of the triad among adolescent figure skaters, dancers, and runners. DESIGN, SETTING, PARTICIPANTS, AND MAIN OUTCOME MEASURES: We advertised our survey on social media platforms: sports-specific forums; Facebook; and Instagram. We received 928 responses. We included female figure skaters, dancers, and runners aged 25 years or younger (N = 712). We asked participants to name the triad components and dichotomized knowledge scores as high or low. We developed a 6-question triad risk scale and defined "at risk" if participants endorsed 3 or more questions. RESULTS: Of 712 participants: 60% were figure skaters; 28% dancers; 12% runners; 78% were adolescents (≤17 years of age); 22% young adults (18-25 years); 12% had heard of the triad. A higher proportion of runners than figure skaters and dancers had high knowledge of the triad (16% vs 6% vs 5%, P < .01). Overall 60% of athletes were "at risk" of the triad, 25% skipped a period for 3 or more months, and 34% had a history of stress fractures or shin splints. Young adults vs adolescents and dancers vs figure skaters and runners had nearly twice the odds of triad risk. CONCLUSION: Most athletes were at risk of the triad but few knew about it. Dancers were at higher risk compared with figure skaters and runners. Efforts should be made to raise awareness of the triad among athletes, parents, and coaches, with special attention paid to the dance community.

Pediatricians' Knowledge and Practices Related to Long-Acting Reversible Contraceptives for Adolescent Girls.

STUDY OBJECTIVE: A 2014 American Academy of Pediatrics (AAP) policy statement identified long-acting reversible contraceptives (LARCs) as first-line choices for adolescents, but pediatricians' current knowledge and practices about intrauterine devices (IUDs) and subdermal contraceptive implants (Implants) is unknown. We aimed to characterize pediatricians' knowledge and practices about LARCs for adolescents. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional online survey emailed to a convenience sample of AAP member pediatricians in New York, Utah, Illinois, and Kansas in 2015 and 2016. The study included 561 practicing pediatricians. MAIN OUTCOME MEASURES: We measured knowledge about the suitability of IUDs and Implants for adolescents using two 7-item scales; a score of 7 indicates all correct. We dichotomized participants' scores as high and low knowledge if they scored ≥85% correct or <85%, respectively. RESULTS: Mean age was 47.4 (±11) years; 73% were female; and 72% general pediatricians. Almost all, 88%, counsel about contraception; 64% counsel about IUDs, and Implants, but only 4.1% insert them; 72% prescribe short-acting hormonal contraceptives; 44% had read the AAP policy statement. Mean score on the knowledge scale was lower for IUDs than for Implants (4.2 vs 5.1, respectively; P < .001). Multivariable regression analysis indicated that female pediatricians, adolescent medicine subspecialists, agreeing that pregnancy is a serious problem for adolescents in their practice, and having read the AAP policy statement predicted high knowledge about IUDs as well as Implants for adolescents. CONCLUSION: Most pediatrician respondents provided reproductive health care for adolescents and counseled about LARCs, but few inserted the devices. We identified knowledge deficits about suitability of IUDs for adolescents.

Reproductive Coercion in High School-Aged Girls: Associations with Reproductive Health Risk and Intimate Partner Violence.

STUDY OBJECTIVE: To determine the prevalence of reproductive coercion, a form of intimate partner violence (IPV) including contraceptive sabotage and pregnancy pressure, among urban high school-aged girls and to examine its associations with reproductive health risks. DESIGN AND SETTING: A self-administered survey completed by high school-aged girls living in high-poverty neighborhoods while awaiting medical care in a pediatric emergency room, inpatient service, school-based, and hospital-based clinic. PARTICIPANTS: One hundred forty-nine sexually active girls aged 14-17 years. INTERVENTIONS AND MAIN OUTCOME MEASURES: To determine the prevalence of reproductive coercion and to examine associations with unprotected sex, sexually transmitted infections, physical IPV, and risk factors for abusive relationships. RESULTS: Twenty-nine of 149 (19%) of girls reported reproductive coercion, most frequently that a romantic or sexual partner had ever: "told them not to use any birth control" (n = 23; 79%); "took off a condom during sex so they would get pregnant" (n = 12; 43%); and "said he would leave them if they didn't get pregnant" (n = 6; 21%). Girls reporting reproductive coercion were nearly 3 times more likely than those not coerced to have had chlamydia (odds ratio [OR], 2.7; 95% confidence interval [CI], 1.01-7.19) and nearly 5 times more likely to report IPV (OR, 4.8; 95% CI, 2.0-11.8). In addition, girls reporting coercion were less likely to have high recognition of abusive behaviors (OR, 0.10; 95% CI, 0.01-0.8) and less likely to have high comfort communicating with their sexual partners (OR, 0.32; 95% CI, 0.1-0.7) than girls not reporting coercion. CONCLUSION: Reproductive coercion is experienced by 1 in 5 high school-aged girls in a high-poverty community and is associated with chlamydia infection and IPV. Awareness of the high prevalence and health risks of coercion might allow for intervention.

Polycystic Ovary Syndrome: An Under-recognized Cause of Abnormal Uterine Bleeding in Adolescents Admitted to a Children's Hospital.

STUDY OBJECTIVE: To evaluate whether ovulatory dysfunction due to polycystic ovary syndrome (PCOS) is a common underlying etiology of abnormal uterine bleeding (AUB) in adolescents who require hospitalization and to explore etiology, treatment, and complications of AUB with severe anemia in adolescents. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We identified female patients aged 8-20 years admitted to a children's hospital for treatment of AUB from January 2000 to December 2014. Our hospital protocol advises hormonal testing for PCOS and other disorders before treatment for AUB. We reviewed medical records and recorded laboratory evaluations, treatments, and final underlying diagnoses as well as recurrences of AUB and readmissions in the subsequent year. RESULTS: Of the 125 subjects, the mean age was 16.5 ± 2.9 years; mean hemoglobin level was 7.0 ± 1.8 g/dL; 54% were overweight/obese; and 41% sexually active. PCOS accounted for 33% of admissions; hypothalamic pituitary ovarian axis immaturity 31%; endometritis 13%; bleeding disorders 10%. Girls with PCOS were more likely to be overweight/obese (74% vs 46%; P < .01) and girls with hypothalamic pituitary ovarian axis immaturity had lower hemoglobin levels (6.4 g/dL vs 7.4 g/dL; P < .05), than girls with all other etiologies of AUB. Treating physicians failed to diagnose endometritis as the etiology for AUB in 4 of 8 girls with positive tests for sexually transmitted infection and no other etiology. CONCLUSION: PCOS was the most common underlying etiology in adolescents hospitalized with AUB. Screening for hyperandrogenemia is important for early diagnosis of PCOS to allow ongoing management and prevention of comorbidities. Endometritis was frequently underestimated as an etiology for AUB.

Treatment of Vitamin D Deficiency in Predominantly Hispanic and Black Adolescents: A Randomized Clinical Trial.

OBJECTIVES: To compare 3 different treatment regimens for vitamin D deficiency in minority adolescents and to explore factors that impact treatment efficacy. STUDY DESIGN: We conducted an 8-week, prospective, open-label, randomized clinical trial in an urban, academic, children's hospital. A total of 183 vitamin D-deficient adolescents, mean 25-hydroxyvitamin D or 25(OH)D 13.7 ± 3.9 ng/mL; mean age 16.6 ± 2.2 years, were randomized into 3 vitamin D3 (cholecalciferol) treatment arms: 50,000 IU/wk; 5000 IU/d; and 1000 IU/d. Serum 25(OH)D and vitamin D binding protein (VDBP) levels were measured pre-and posttreatment; 122 (67%) participants completed posttreatment measures. Complete-case and multiple-imputation, intention-to-treat analyses were performed. RESULTS: Mean change in 25(OH)D level posttreatment was significantly different among the 3 arms, 24.9 ± 15.1 vs 21.0 ± 15.2 vs 6.2 ± 6.5 ng/mL, for 50,000 IU, 5000 IU, and 1000 IU doses, respectively, P < .001. Both high-dose treatments were effective in increasing the 25(OH)D level out of deficiency range (≥ 20 ng/mL) in more than 80% of participants, and 60% remained deficient after low-dose treatment. Only 72%, 56%, and 2% achieved vitamin D sufficiency (>30 ng/mL) with 50,000 IU, 5000 IU, and 1000 IU doses, respectively, P < .001. Obese participants had substantially less mean change in 25(OH)D level after treatment than normal-weight participants, 13.7 ± 10.7 vs 21.9 ± 16.9 ng/mL, P < .001. Mean baseline VDBP level was almost twice as high in Hispanic compared with black participants (P < .001) and did not alter treatment response or change with treatment. CONCLUSIONS: Adult-sized adolescents require 8 weeks of high-dose cholecalciferol, at least 5000 IU/d, to correct deficiency. Obese adolescents have poorer response to treatment and may need higher doses than nonobese youth. Hispanic and black adolescents have different VDBP levels but similar treatment responses. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01784029.

Predictors of Early Discontinuation of Effective Contraception by Teens at High Risk of Pregnancy.

STUDY OBJECTIVE: In the United States, teen pregnancy rates are declining. However, the United States still has the highest teen pregnancy rate among high-income countries. Understanding factors that predict discontinuation of effective contraception might help to further decrease teen pregnancy. We aimed to assess predictors of early discontinuation of effective contraception during typical use by high-risk teens. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We recruited 145 women aged 13-20 years (mean, 17.7 ± 1.8 years); 68% (99/145) Hispanic; 26% (38/145) black; 14% (20/145) ever pregnant; and 4% (6/145) high school dropouts who chose an effective contraceptive method during a health care visit and we prospectively assessed use of the method after 6 months. Contraceptive choices of the 130 participants who were reassessed at 6 months (90% retention) were: intrauterine device (IUD), 26% (34/130); depot medroxyprogesterone acetate (DMPA), 8% (10/130); combined oral contraceptives (COCs), 48% (62/130); transdermal patch (Patch), 13% (17/130); and intravaginal ring (Ring), 5% (7/130). RESULTS: After 6 months, only 49 of 130 (38%) continued their chosen method; 28 of 130 (22%) never initiated the method; and 53 of 130 (40%) discontinued. Users and nonusers at 6 months did not differ according to cultural and/or social characteristics (age, ethnicity, acculturation, education, health literacy) but differed according to contraceptive method type. For the 102 of 130 who initiated a method, 88% continued use of the IUD, 20% DMPA, 43% COC, 17% Patch and Ring (P < .001). Using Cox proportional hazards multivariable analysis, compared with IUDs, all other methods predicted discontinuation: DMPA (hazard ratio [HR], 5.6; 95% confidence interval [CI], 1.2-26.7; P < .05); COCs (HR, 6.6; 95% CI, 1.8-25; P < .01); Patch and Ring (HR, 12; 95% CI, 3.0-48; P < .001). Discontinuation was also predicted by past use of hormonal contraceptives (HR, 1.9; 95% CI, 1.0-3.6; P < .05) and high school dropout (HR, 8.2; 95% CI, 1.6-41; P < .01). CONCLUSION: Contraceptive method type is the strongest predictor of early discontinuation; compared with IUDs, all other methods are 6-12 times more likely to be discontinued. Cultural and/or social characteristics, with the exception of school dropout, are of little predictive value. Increasing the use of IUDs by high-risk teens could decrease discontinuation rates and possibly teen pregnancy rates.

Clinical utility of magnetic resonance imaging and ultrasonography for diagnosis of polycystic ovary syndrome in adolescent girls.

OBJECTIVE: To evaluate ovarian morphology using three-dimensional magnetic resonance imaging (MRI) in adolescent girls with and without polycystic ovary syndrome (PCOS). Also compare the utility of MRI versus ultrasonography (US) for diagnosis of PCOS. DESIGN: Cross-sectional study. SETTING: Urban academic tertiary-care children's hospital. PATIENT(S): Thirty-nine adolescent girls with untreated PCOS and 22 age/body mass index (BMI)-matched controls. INTERVENTION(S): Magnetic resonance imaging and/or transvaginal/transabdominal US. MAIN OUTCOME MEASURE(S): Ovarian volume (OV); follicle number per section (FNPS); correlation between OV on MRI and US; proportion of subjects with features of polycystic ovaries (PCOs) on MRI and US. RESULT(S): Magnetic resonance imaging demonstrated larger OV and higher FNPS in subjects with PCOS compared with controls. Within the PCOS group, median OV was 11.9 (7.7) cm(3) by MRI compared with 8.8 (7.8) cm(3) by US. Correlation coefficient between OV by MRI and US was 0.701. Due to poor resolution, FNPS could not be determined by US or compared with MRI. The receiver operating characteristic curve analysis for MRI demonstrated that increasing volume cutoffs for PCOs from 10-14 cm(3) increased specificity from 77%-95%. For FNPS on MRI, specificity increased from 82%-98% by increasing cutoffs from ≥ 12 to ≥ 17. Using Rotterdam cutoffs, 91% of subjects with PCOS met PCO criteria on MRI, whereas only 52% met criteria by US. CONCLUSION(S): Ultrasonography measures smaller OV than MRI, cannot accurately detect follicle number, and is a poor imaging modality for characterizing PCOs in adolescents with suspected PCOS. For adolescents in whom diagnosis of PCOS remains uncertain after clinical and laboratory evaluation, MRI should be considered as a diagnostic imaging modality.

The influence of individual, partner, and relationship factors on HIV testing in adolescents.

Early identification of HIV by increasing testing is a national priority; however, little is known about HIV testing behaviors in high school age adolescents. We examined the association of individual, partner, and relationship factors with HIV testing using a computer-assisted survey administered from 2003 to 2006 in a community sample of 980 sexually active 14- to 17-year-olds (56% female, 55% Latino, 25% African American) living in a jurisdiction with a high AIDS burden. Twenty percent reported their first sexual encounter as having occurred when they were <13 years of age, 33% had had four or more lifetime sexual partners, 21% reported high partner HIV-risk behavior, and 428 (44%) had been tested for HIV. In our final regression model, independent associations with HIV testing included being female (OR=1.68 [1.23-2.30]), older (OR=1.41 [1.21-1.65]), and having had four or more lifetime sexual partners (OR=2.24 [1.64-3.05]). The strongest independent predictor of HIV testing was having high HIV-related partner communication (OR=3.70 [2.77-4.94]). Being in a serious committed relationship (OR=1.39 [1.02-1.87]) was also independently associated with HIV testing, whereas reporting high worry about HIV/AIDS (OR=0.53 [0.40-0.71]) was independently negatively associated with HIV testing. High HIV/AIDS knowledge, high partner HIV risk behavior, and young age at first sexual encounter were not associated with testing. These findings suggest that, for high school aged adolescents, optimal strategies to promote HIV testing should look beyond increasing HIV/AIDS knowledge and identifying individual risk behaviors to also considering the role of partners and relationships and their influence on testing behavior.

Independent and synergistic associations of asthma and obesity with systemic inflammation in adolescents.

INTRODUCTION: Both asthma and obesity often occur in the same individual. Each increases the risk of cardiovascular disease (CVD) with systemic inflammation likely playing a vital role. We examined the independent and synergistic associations of asthma and obesity with systemic inflammation using high-sensitivity C-reactive protein (hs-CRP) levels in adolescents. METHODS: This study involves the cross-sectional design carried out in the adolescent and respiratory medicine practices in a children's hospital. Out of 124 adolescents (mean age 16.1 ± 2.3 years), who were either of obese (N = 75) or of normal weight (N = 49). 51 had asthma (18 normal weight and 33 obese). RESULTS: hs-CRP levels were higher in obese versus normal weight groups (geometric mean ± SD: 2.38 ± 2.91 vs. 0.72 ± 3.54; p < .001), and in the asthmatic versus non-asthmatic groups (geometric mean ± SD: 1.21 ± 3.71 vs.1.96 ± 3.28; p = .039). We found a trend of increasing hs-CRP levels across the four groups (p < .001), with the obese asthmatic group having the highest level. In multivariate regression, we found a strong association between obesity and log-CRP (ß ± SE: 1.43 ± 0.23; p < .001) and a moderate association between asthma and log-CRP (ß ± SE: 0.48 ± 0.21; p < .028), with additive synergy between obesity and asthma. CONCLUSIONS: Both asthma and obesity are independently and synergistically associated with systemic inflammation. These findings underline the need of a multifaceted approach to address CVD risk in adolescence.

Sleep and cardiometabolic function in obese adolescent girls with polycystic ovary syndrome.

OBJECTIVE: To compare the polysomnography findings and cardiometabolic function among adolescent girls with polycystic ovary syndrome (PCOS) and matched female and male controls. METHOD: Retrospective chart review of electronic medical records of 28 girls with PCOS (age: 16.8±1.9 years, body mass index (BMI) Z-score 2.4±0.4), 28 control females (age: 17.1±1.8, BMI Z-score 2.4±0.3) and 28 control males (age: 16.6±1.6, BMI Z-score 2.5±0.5) in a tertiary care centre. RESULTS: The prevalence of obstructive sleep apnoea (OSA) was higher in girls with PCOS compared to control females (16/28 (57%) vs. 4/28(14.3%), p<0.01); however, it was comparable to that of the control males (16/28(57%) vs. 21/28(75%), p=0.4). Girls with PCOS had a significantly higher prevalence of insulin resistance compared to control females and control males (20/28 (71.4%) vs. 9/22 (41.0%) (p=0.04) vs. 8/23 (34.8%) (p=0.01). Among girls with PCOS, those with OSA had significantly higher proportions of metabolic syndrome (MetS) (9/16 (56.3%) vs. 1/12 (8.3%) p=0.03), higher insulin resistance (14/16 (87.5%) vs. 6/12 (50%), p=0.04), elevated daytime systolic blood pressure (128.4±12.8 vs. 115.6±11.4, p<0.01), lower high-density lipoprotein (HDL) (38.6±8.7 vs. 49±10.9, p=0.01) and elevated triglycerides (TG) (149.7±87.7 vs. 93.3±25.8, p=0.03) compared to those without OSA. CONCLUSIONS: We report a higher prevalence of OSA and metabolic dysfunction in a selected group of obese girls with PCOS referred with sleep-related complaints compared to BMI-matched control girls without PCOS. We also report higher prevalence of cardiometabolic dysfunction in girls with PCOS and OSA compared to girls with PCOS without OSA.
