To identify factors associated with bothersome implant-associated uterine bleeding, and to evaluate the impact of bleeding management on implant discontinuation.We analyzed a quality improvement database of implant insertions (n = 825) at three adolescent/young adult programs and described individuals with and without reported bothersome bleeding. We utilized logistic regression to assess for factors associated with bleeding.Implant recipient mean age was 18.9 ± 2.6 years, and 27% reported having subsequent bothersome uterine bleeding. Recipients had increased odds of reporting such bleeding if they had previously irregular menses (odds ratio [OR] = 1.36; 95% confidence interval [CI]: 1.11-1.68 irregular and infrequent, OR = 1.41; 95% CI: 1.07-1.86 irregular and frequent) or sought the implant for menstrual management purposes exclusively (OR = 1.67; 95% CI 1.42-1.96) or in combination with contraceptive need (OR 1.65; 95%: CI 1.57-1.72). Prior use of the progestin injection or implant was associated with lower odds of subsequent bleeding report (OR = 0.63; 95% CI: 0.54-0.73; OR = 0.54; 95% CI: 0.39-0.75, respectively). Medication management of bleeding was associated with the likelihood of implant discontinuation at 1 year compared to those with untreated bleeding (hazard ratio 1.98 times, 95% CI: 1.39-2.81). The implant was continued for 3 years in over 50% of recipients with ever-managed bothersome bleeding.Individuals with historically irregular menses and those seeking the implant for menstrual management more often reported bothersome bleeding. Treating such bleeding with medication was associated with higher 1-year discontinuation rates, although many continued implant use for 3 years. Such findings may influence implant preinsertion counseling and/or postinsertion bleeding management.

To describe adolescent and young adult (AYA) long-acting reversible contraception (LARC) follow-up care via telemedicine in the year following the COVID-19 pandemic onset DESIGN: Longitudinal cohort study SETTING: Three academic adolescent medicine clinics in the United States PARTICIPANTS: AYAs using LARC INTERVENTIONS: None MAIN OUTCOME MEASURES: The main outcome measures were patient characteristics, visit information (frequency, timing, and modality), patient-reported symptoms, and outcomes for those presenting for LARC follow-up care between April 1, 2020, and March 31, 2021. Descriptive statistics were used to describe the sample. χOf the 319 AYAs (ages 13.6-25.7 years), 40.1% attended at least one LARC telemedicine visit. Patients attending any telemedicine encounter vs only in-person visits had similar demographic and clinical characteristics. Of the 426 follow-up visits, 270 (63.4%) were conducted in person and 156 (36.6%) were performed via telemedicine. Most visits (62.7%) occurred within 12 months of device insertion. Reports of bothersome uterine bleeding beyond patient expectations (OR = 1.26; 95% CI, 0.80-1.96), any symptom (OR = 1.40; 95% CI, 0.94-2.10), or 2 or more symptoms (OR = 1.22; 95% CI, 0.67-2.22) at follow-up was not associated, positively or negatively, with mode of follow-up. Management of bleeding (OR = 1.27; 95% CI, 0.56-2.89), management of acne (P = .46), and need for rapid follow-up (P = .33) were similar between follow-up modalities.Patient demographic/clinical characteristics and visit outcomes were similar between telemedicine and in-person LARC follow-up. Telemedicine could play an important role in AYA LARC care.

Macromastia is common among adolescents and young women and has well-documented negative physical and psychosocial effects. The pathogenesis of idiopathic macromastia has been attributed to increased end organ sensitivity to circulating gonadal hormones. Despite the known negative effects of macromastia, there is a paucity of literature examining the clinical risk factors associated with macromastia severity in this age group.In this cross-sectional study, standardized clinical forms were administered to patients between the ages of 12 and 21 years undergoing reduction mammaplasty. Data were collected pertaining to patient demographics, biometrics, breast symptoms, medical and family history, and breast tissue resection mass at the time of reduction. Resection mass was normalized to patient body surface area in analyses.A total of 375 patients were included in analyses. Mean age at surgery was 18.1 years. The following risk factors were positively associated with macromastia severity in both univariate and multivariate logistic regression models: overweight or obesity, racial or ethnic minority status, patient-reported gynecologic or endocrine complaints, and early menarche ( p0.05, all). More severe cases of macromastia were associated with approximately three times the odds of being overweight or obese or achieving menarche before 11 years old.In our sample, overweight or obesity, racial or ethnic minority status, early menarche, and patient-reported gynecologic or endocrine complaints were all positively associated with macromastia severity. Awareness of these factors can empower physicians to identify and address modifiable risk factors to prevent progression to more severe disease. Macromastia itself should prompt screening for gynecologic or endocrine complaints with referral as indicated.Risk, III.

We described trends in pelvic pain characteristics over 2 years of follow-up among adolescents and adults with and without endometriosis participating in the longitudinal observational cohort of the Women's Health Study: From Adolescence to Adulthood, using data reported at baseline and at years 1 and 2 of follow-up. Participants completed a questionnaire at baseline (between November 2012 and May 2019) and annually thereafter that included validated measures of severity, frequency, and life interference of dysmenorrhea, acyclic pelvic pain, and dyspareunia. Our study population included 620 participants with surgically confirmed endometriosis (rASRM stage I/II = 95%) and 671 community-based and hospital-based controls, with median age = 19 and 24 years, respectively. The proportion reporting hormone use varied across the 3 years ranging from 88% to 92% for cases and 56% to 58% for controls. At baseline, endometriosis cases were more likely to report severe, frequent, and life-interfering dysmenorrhea, acyclic pelvic pain, and dyspareunia compared with controls. Among cases, frequency and severity of dysmenorrhea and dyspareunia were relatively static across 2 years. However, acyclic pelvic pain improved. Severe acyclic pain decreased from 69% at baseline to 46% at year 2. Daily pain decreased from 28% to 14%, and life interference from 68% to 38%. Trends among controls remained fairly stable across 2 years. Among endometriosis cases who completed the questionnaire at all 3 time points, 18% reported persistent, severe acyclic pelvic pain at all 3 time points. Over time, different trends were observed by pelvic pain type among endometriosis cases and controls, supporting the importance of assessing multidimensional features of pelvic pain.

To determine if women with endometriosis experience lower urinary tract symptoms (LUTSs) more often than those without.Cross-sectional analysis at enrollment in a longitudinal cohort.Enrollment at 2 academic hospitals and from the local community.This analysis included 1,161 women with (n = 520) and without (n = 641) surgically confirmed endometriosis who were enrolled in the Women's Health Study: from Adolescence to Adulthood between 2012 and 2018.Not applicable.Prevalence of LUTSs, including stress incontinence, urgency and frequency, straining with urination, incomplete bladder emptying, hematuria, dysuria, and bladder pain using standardized questionnaires.The primary outcomes were that women with endometriosis reported the following more often than those without: difficulty passing urine (7.9% vs. 2%; crude odds ratio [OR], 4.14 [95% confidence interval {CI}, 2.19-7.80]; adjusted OR [aOR], 4.31 [95% CI, 2.07-8.95]); still feeling full after urination (18.8% vs. 4.7%; crude OR, 4.73 [95% CI, 3.08-7.25]; aOR, 4.67 [95% CI, 2.88-7.56]); having to urinate again within minutes of urinating (33.1% vs. 17.0%; crude OR, 2.41 [95% CI, 1.83-3.18]; aOR, 2.49 [95% CI, 1.81-3.43]), dysuria (11.7% vs. 4.9%; crude OR, 2.55 [95% CI, 1.62-4.01]; aOR, 2.38 [95% CI, 1.40-4.02]); and pain when the bladder is full (23.0% vs. 4.9%; crude OR, 5.79 [95% CI, 3.82-8.78]; aOR, 6.04 [95% CI, 3.74-9.76]). For the secondary outcomes, among female participants with endometriosis, we observed that the odds of LUTS did not differ by the revised American Society for Reproductive Medicine stage (I/II vs. III/IV) or duration of endometriosis-associated symptoms.Women with surgically confirmed endometriosis were more likely to report LUTS than those without.

Objective To estimate the efficacy and safety of a novel nonhormonal therapeutic agent, cabergoline, compared with that of the standard clinical therapy, norethindrone acetate (NETA), for the treatment of endometriosis-associated pain in young women with endometriosis. Design Randomized, double-blind, placebo-controlled pilot study. Setting Tertiary care center. Patient(s) Women (n = 9) with surgically confirmed endometriosis. Intervention(s) A random, double-blind assignment to either NETA (5 mg/day) + placebo twice weekly or cabergoline (0.5 mg) twice weekly + placebo daily for 6 months. Main Outcome Measure(s) We collected the measures of pelvic pain and laboratory parameters every 3 months. Result(s) We observed a decrease in pain scores and increase in pain relief in women randomized to receive cabergoline, who appeared to show similar or more improvements than women treated with NETA. The serum measures of vascular endothelial growth factor receptor 1 declined over 6 months in those who received cabergoline. Cabergoline was well tolerated, and no serious adverse events occurred. Conclusion(s) Safe, effective adjunct treatments are lacking for patients with endometriosis who do not respond to standard care. Because the growth of endometriosis requires angiogenesis, blood vessel growth is an attractive therapeutic target. This pilot study suggests that cabergoline, a vascular endothelial growth factor pathway inhibitor, is an effective therapeutic option for women with chronic pain due to endometriosis. Building upon this investigation, we will conduct larger, randomized trials of cabergoline, advancing research on the best treatments for endometriosis—particularly disease resistant to hormonal therapies. Clinical Trial Registration Number clinicaltrials.gov; registration number NCT02542410.

Study Objectives Hypothalamic amenorrhea is common in adolescents and young adults (AYAs) with anorexia nervosa (AN), and ovarian reserve is not routinely assessed. AN increases rates of fertility problems, but how or when AN negatively influences future fertility is unclear. We sought to determine whether biomarkers of ovarian reserve were impacted in AYA with AN. Design Cross-sectional study. Setting Tertiary care center. Participants Females with AN and amenorrhea (n = 97) at the pre-intervention visit of a clinical trial, n = 19 females without an eating disorder or menstrual dysfunction. Main Outcome Measures Serum anti-Mullerian hormone (AMH) concentrations. Results AMH levels were higher in AYA with AN than unaffected adolescents (4.7 vs. 3.2 ng/mL; P = .03). Neither FSH nor inhibin B differed between groups. In 19.6% of participants with AN, AMH levels were elevated above the normal range (>6.78 ng/mL). These subjects had a longer disease duration than those with normal AMH levels (9 vs. 3 mos; P = .03); age or degree of malnutrition did not differ between AN subjects with normal or elevated AMH. Conclusions AMH levels appear to be normal or elevated in AYA with AN. Low AMH in a patient with AN should raise clinical concern regarding ovarian reserve, and should not be attributed to degree of malnutrition alone. Currently, AMH is not regularly assessed during routine AN clinical care. However, our findings suggest some clinical utility in identifying those patients with reduced ovarian reserve. Potential links between the hypothalamic amenorrhea suffered by patients with AN and PCOS should be explored.

The combined oral contraceptive pill, containing both estrogen and progestin, is commonly prescribed to adolescents for numerous health benefits. However, there is concern among patients and providers that its use may exacerbate breast growth. This retrospective, case-control study examined the association between combined oral contraceptive pill use and macromastia-related breast hypertrophy and symptoms in adolescents.A total of 378 patients undergoing reduction mammaplasty between the ages of 12 and 21 years were assessed for baseline and postoperative breast symptoms and combined oral contraceptive pill use. In addition, the medical records of 378 female controls of the same age range were retrospectively reviewed.Although a lower proportion of the macromastia cohort used any hormonal contraception compared to controls (37.8 percent versus 64.8 percent; OR, 0.33; 95 percent CI, 0.24 to 0.44; p0.001), they were more often prescribed combined oral contraceptive pills (82.5 percent versus 52.7 percent; OR, 1.93; 95 percent CI, 1.29 to 2.68; p0.001). Participants with macromastia who used combined oral contraceptive pills had a smaller median normalized amount of breast tissue resected during reduction mammaplasty than those who never used hormonal contraception (639.5 g/m 2 versus 735.9 g/m 2 ; p = 0.003). Combined oral contraceptive pills were not associated with breast-related symptoms or clinical impairment, or postoperative breast growth ( p0.05 for all).Combined oral contraceptive pill use during adolescence may be associated with developing less severe breast hypertrophy. Combined oral contraceptive pills do not appear to exacerbate macromastia-related symptoms or impact postoperative growth in young women following reduction mammaplasty. Although additional research is needed, providers are encouraged to consider combined oral contraceptive pills for their patients with macromastia when indicated and appropriate.Risk, III.

To analyze clinical, metabolic, hormonal, and ultrasound characteristics of adolescents with polycystic ovary syndrome phenotypes.We performed a retrospective analysis of quality improvement data. We divided patients according to phenotype on the basis of clinical or biochemical diagnosis of hyperandrogenism (HA), irregular menstruation (IM), and presence or absence of polycystic ovarian morphology (PCOM) on pelvic ultrasound (PUS) images, if obtained. The 5 resulting groups were: (1) HA/IM/normal PUS, n = 28; (2) HA/PCOM, n = 10; (3) IM/PCOM, n = 18; (4) HA/IM/PCOM, n = 40; and (5) HA/IM/no PUS obtained, n = 80. We compared parameters between groups using the nonparametric Wilcoxon rank sum test.Boston Children's Hospital, 2012-2016.One hundred seventy-six girls and young women aged 11-25 years.None.(1) Clinical, metabolic, and hormonal characteristics; and (2) PUS measurements.Groups with HA had significantly higher acne scores, Ferriman-Gallwey scores, and total and free testosterone concentrations than groups without HA. Significant differences in hemoglobin A1c were found between the IM/PCOM and HA/IM/PCOM groups (5.1% vs 5.3%; P = .01) and the IM/PCOM and HA/IM/no PUS groups (5.1% vs 5.3%; P .01). In patients who had ultrasound performed, 49/94 (52.1%) met PCOM criteria on the basis of ovarian size, 37/94 (39.4%) on the basis of follicle number, and 27/94 (28.7%) on both; 10/94 (10.5)% had incidental findings on ultrasound, with 2 patients requiring further management.Limited differences in clinical, metabolic, and hormonal characteristics exist between adolescents with different phenotypes of polycystic ovary syndrome, and are mostly related to the presence or absence of HA. Of patients with ultrasound examinations, only 2 had clinically actionable incidental findings.

The purpose of this study is to quantify the prevalence of dyspareunia and its impact on quality of life (QOL) in adolescent and young adult women (AYA) diagnosed with endometriosis.Eligible participants from the Women's Health Study: From Adolescence to Adulthood, a longitudinal cohort study, were AYA 18-25 years who reported having had sexual intercourse. We included n = 151 AYA with a surgical diagnosis of endometriosis and n = 287 without known endometriosis. Participants completed a questionnaire including the Short Form-36 (SF-36) QOL survey, on which lower scores indicate impairment. Dyspareunia was defined as answering "yes" to having had pain during/within 24 hours following sexual intercourse. Normative-based scores for SF-36 subscales were calculated and compared between groups using linear regression adjusted for age, body mass index, educational level, and race.Participants with endometriosis experienced dyspareunia twice as often (79%) than AYA without endometriosis (40%, p.0001). In participants with and without endometriosis, all SF-36 subscale scores were significantly lower in AYA with dyspareunia than without. For six subscales, the negative impact was significantly stronger in AYA with endometriosis than those without, and mean scores were all less than the normative score, indicating impairment.More than three quarters of AYA with endometriosis and two thirds without experience dyspareunia that negatively impacts both physical and mental health QOL scores. This impairment is stronger in those with endometriosis. Given the importance of relationships and peer engagement for identity formation during adolescence, dyspareunia could be particularly impactful. Clinicians should ask patients not only about contraception and prevention of sexually transmitted infections, but inquire about how dyspareunia may impact mental and physical well-being.

Background Young women with congenital breast asymmetry have impaired psychological well-being and self-esteem. However, little is known regarding the effects of surgical intervention in this population. This cohort study aims to assess postoperative changes in health-related quality of life following surgical treatment of breast asymmetry in young women using a prospective, longitudinal study design. Methods From 2008 to 2018, 45 young women undergoing surgical correction of breast asymmetry of benign cause and 101 unaffected, female controls completed the following surveys: Short-Form 36v2, Rosenberg Self-Esteem Scale, and Eating-Attitudes Test-26. Surveys were administered at baseline and at up to 9-year follow-up. Results Participants with breast asymmetry scored significantly worse than controls at baseline on the Rosenberg Self-Esteem Scale and in two Short-Form 36v2 domains: Social-Functioning and Role-Emotional. Asymmetry participants experienced significant postoperative improvements on the Rosenberg Self-Esteem Scale, and in three Short-Form 36v2 domains: Role-Physical, Social Functioning, and Mental Health. These improvements were sustained for a minimum of 5 years. Postoperatively, asymmetry participants' quality of life was comparable to controls and did not vary by age at the time of surgery, asymmetry severity, or diagnosis. Conclusions Surgical treatment of breast asymmetry in young women yields significant and sustained improvements in psychosocial quality of life. Postoperatively, patients returned to a level of functioning commensurate with their peers. Clinical question/level of evidence Therapeutic, IV.

Endometriosis is a common gynecologic disorder often associated with severe pelvic pain and infertility with few known modifiable risk factors. We investigated whether in utero and early life exposures are associated with surgically diagnosed endometriosis among adolescents and young adults.This case-control study, including 295 laparoscopically-confirmed endometriosis cases and 309 population-based controls aged25 years, was conducted using data from The Women's Health Study: From Adolescence to Adulthood which enrolled participants from 2012 to 2018. Information on in utero and early life factors were collected using a modified WERF EPHect questionnaire at enrollment, including their mother's age at delivery, birthweight, gestation length, exposure to smoking in utero and secondhand smoke during childhood up to age 13, and if the participant was breastfed.Median age at enrollment was 17 years (range 12-24) in cases and 22 years (range 7-24) in controls, with 83 % and 68 % non-Hispanic whites, respectively. The majority of cases (95 %) were rASRM stage I or II at diagnostic surgery. Exposure to breastfeeding in early life was associated with lower odds of endometriosis diagnosis (OR = 0.39, 95 % CI = 0.21-0.74). Exposure to secondhand smoke during childhood due to maternal smoking was associated with increased odds of endometriosis diagnosis (OR = 2.70, 95 % CI = 1.11-6.60).Among adolescents and young adults, our data suggest exposures to breastfeeding in early life and secondhand smoke during childhood may be associated with endometriosis risk, providing insight into etiologic pathways to be explored in this young population.

Purpose of review Long-acting reversible contraception (LARC) is increasingly used by adolescents and young adults (AYAs). Subsequent to LARC insertion, AYAs are presenting to their primary care providers with LARC concerns. This article seeks to equip primary care clinicians with the tools necessary to assess and manage common LARC-associated side effects. Recent findings Side effects are common with progestin-only LARC, and can precipitate early discontinuation of an otherwise effective, low-maintenance form of contraception. Abnormal uterine bleeding, pelvic pain, acne, and weight change are often cited as progestin-only LARC side effects, yet the causes are poorly understood despite extensive research. While most side effects improve with time, therapeutic interventions are available for patients with undesirable side effects that prefer medical management. Research emphasizes the importance of proper patient counseling and clinical follow-up. Summary Counseling remains essential in the management of LARC-associated side effects. However, options are available to temporarily mitigate such side effects and increase LARC satisfaction. While these therapeutic options are prescribed based on expert opinion, such regimens remain inadequately studied in AYA populations.

BACKGROUND: Adolescents with endometriosis are a particularly underserved population who struggle with chronic pain. Despite widespread use, there are no published trials examining the individual effects of vitamin D and omega-3 (n–3) fatty acid supplementation on endometriosis-associated pain in adolescents. OBJECTIVES: We aimed to determine whether supplementation with vitamin D or ω-3 fatty acids remediates pain, changes frequency of pain medication usage, or affects quality of life in young women with endometriosis. METHODS: Women (aged 12–25 y) with surgically confirmed endometriosis and pelvic pain enrolled in a double-blind, randomized, placebo-controlled trial. The primary outcome was pain measured by the visual analog scale (VAS). Secondary outcomes were quality of life, pain catastrophizing, and pain medication usage. Participants were randomly assigned to receive 2000 IU vitamin D(3), 1000 mg fish oil, or placebo daily for 6 mo. RESULTS: A total of 147 women were screened and 69 were randomly assigned as follows: 27 to vitamin D(3); 20 to fish oil; and 22 to placebo. Participants in the vitamin D arm experienced significant improvement in VAS pain [mean (95% CI) worst pain in the past month, from baseline to 6 mo: 7.0 (6.2, 7.8) to 5.5 (4.2, 6.8), P = 0.02]; however, an improvement of nearly identical magnitude was observed in the placebo arm [6.0 (5.1, 6.9) to 4.4 (3.0, 5.8), P = 0.07]. A more modest improvement was observed in the fish oil arm [5.9 (4.8, 7.0) to 5.2 (3.7, 6.8), P = 0.39]. Neither of the intervention arms were statistically different from placebo. CONCLUSIONS: In young women with endometriosis, supplementation with vitamin D led to significant changes in pelvic pain; however, these were similar in magnitude to placebo. Supplementation with fish oil resulted in about half of the VAS pain reduction of the other 2 arms. Studies are needed to better define the physiology underlying the observed reduction in pain score in the placebo arm that persisted across 6 mo. This trial was registered at clinicaltrials.gov as NCT02387931.

Persistent adolescent gynecomastia negatively affects health-related quality of life. Surgery results in psychosocial improvements, but the effects of postoperative complications on health-related quality of life are unknown. The authors examined whether complications following adolescent gynecomastia surgery impact postoperative health-related quality of life.Patients aged 12 to 21 years who underwent surgical correction of unilateral/bilateral gynecomastia between 2007 and 2019 were enrolled (n = 145). Relevant demographic and clinical data were obtained from medical records. Fifty-one patients completed the following surveys preoperatively, and at 6 months and 1, 3, 5, 7, 9, and 11 years postoperatively: 36-Item Short-Form Health Survey (Version 2), Rosenberg Self-Esteem Scale, and the 26-item Eating Attitudes Test.Within a median period of 8.6 months, 36 percent of breasts experienced at least one complication. The most common were residual tissue (12.6 percent), contour irregularities (9.2 percent), and hematomas (7.8 percent). Patients reported significant postoperative improvements in self-esteem and in seven health-related quality-of-life domains (Physical Functioning, Role-Physical, Bodily Pain, Vitality, Social Functioning, Role-Emotional, and Mental Health) at a median of 33.3 months. Postoperative survey scores did not vary by grade or procedure, or largely by body mass index category or complication status. However, patients aged younger than 17 years at surgery scored significantly higher than older patients in the Short-Form Health Survey Vitality and Mental Health domains postoperatively.Health-related quality-of-life improvements are achievable in adolescents through surgical correction of persistent gynecomastia. Postoperatively, patients largely experienced similar health-related quality-of-life gains irrespective of complication status, grade, surgical technique, or body mass index category. Minor postcorrection complications are but do not appear to limit postoperative health-related quality-of-life benefits.

Endometriosis affects reproductive-aged females and varies considerably in terms of symptom presentation, morphologic features, and treatment response. Most studies investigating symptom recurrence after an endometriosis-related surgery have been conducted among adults. The Endometriosis pain QUality aftEr Surgical Treatment (EndoQUEST) Study was established to assess characteristics and biomarkers that are associated with pain remediation and improved quality of life after an endometriosis-related surgery among adolescents and young adults. This paper describes the EndoQUEST methodology, summarizes baseline descriptive factors, and compares characteristics by participant retention status. We enrolled 100 surgically-confirmed endometriosis participants aged 12–23 years who provided questionnaire data on reproductive and behavioral factors, pain characteristics and quality of life at three time points; before surgery, 6 weeks to 26 weeks after surgery, and 1 year after surgery. Among these 100 participants, 88 provided blood and/or saliva at all three time points, while 12 provided blood and/or saliva samples only before surgery and 6 to 26 weeks after surgery. There was little evidence of lost to follow-up at 1 year after surgery due to pain symptoms, as pain and quality of life characteristics were similar between participants who completed the questionnaire 1 year after surgery and those who did not. Analyses utilizing these longitudinal data will advance personalized treatment decision making for adolescents and young adults with endometriosis.

To report on long-acting reversible contraception (LARC) experience and continuation rates in the Adolescent Medicine LARC Collaborative.LARC insertion data (682 implants and 681 intrauterine devices [IUDs]) were prospectively collected from January 1, 2017, through December 31, 2019, across 3 Adolescent Medicine practices. Follow-up data through December 31, 2020, were included to ensure at least 1 year of follow-up of this cohort. Continuation rates were calculated at 1, 2, and 3 years, overall and by Adolescent Medicine site, as were descriptive statistics for LARC procedural complications and patient experience.Implant and IUD insertion complications were uncommon and largely self-limited, with no IUD-related uterine perforations. Uterine bleeding was the most frequently reported concern at follow-up (35% implant, 25% IUD), and a common reason for early device removal (45% of implant removals, 32% of IUD removals). IUD malposition or expulsion occurred following 6% of all insertions. The pooled implant continuation rate at 1 year was 87% (range, 86%-91% across sites; P = .63), 66% at 2 years (range, 62%-84%; P = .01), and 42% at 3 years (range, 36%-60%; P = .004). The pooled IUD continuation rate at 1 year was 88% (range, 87%-90% across sites; P = .82), 77% at 2 years (range, 76%-78%; P = .94), and 60% at 3 years (range, 57%-62%; P = .88).LARC is successfully provided in Adolescent Medicine clinical settings, with continuation rates analogous to those of well-resourced clinical trials. Uterine bleeding after LARC insertion is common, making counselling imperative. Future analyses will assess whether the medical management of LARC-related nuisance bleeding improves continuation rates in our Adolescent Medicine patient population.

Adolescence is a challenging time, and an increasing number of young people are seeking plastic surgery. With the rise of health-related quality of life studies in plastic surgery, it is critical to understand the natural variation and changes in health-related quality of life for this population.In this longitudinal, cohort study validated surveys were administered to cisgender participants aged 12-21 years: Short-Form 36v2, Rosenberg Self-Esteem Scale, Breast-Related Symptoms Questionnaire, and Eating-Attitudes Test-26. Surveys were administered at baseline and up to 9 years follow-up. At the time of enrollment, participants were in a current state of good health with no considerable past or current medical, surgical, or psychological history.A total of 149 female and 75 male participants were included, with a median (interquartile range) baseline age of 16.0 (4.4) years and follow-up time of 3.3 (4.1) years. Over the study period, girls who were not overweight or obese experienced significant declines in five SF-36 domains (general health, vitality, social functioning, role-emotional, and mental health) and on the Rosenberg Self-Esteem Scale, Breast-Related Symptoms Questionnaire, and Eating-Attitudes Test-26 (Adolescence is a challenging time, on which plastic surgery-related concerns are superimposed. Our findings suggest that girls may be more at risk for developing psychosocial deficits that worsen over adolescence and young adulthood. This observation is critical for the interpretation and contextualization of health-related quality of life in adolescent plastic surgery patients.

Purpose The aim of this study is to examine age at menarche across sexual orientation groups. Methods Data were obtained from 131,090 female participants, born 1947–2001, in 3 longitudinal studies—the Growing Up Today Study and Nurses’ Health Study 2 and 3. We estimated the association between sexual orientation and age at menarche using regression models adjusted for age, race/ethnicity, birthweight, height, and body mass index. Results Compared to heterosexual participants, sexual minorities were younger at menarche. Sexual minorities were more likely to have early menarche (≤11 years) and less likely to have late menarche (≥14 years) compared to heterosexual girls. As an example of this pattern, Nurses’ Health Study 3 bisexual participants were >30% more likely than heterosexuals to have early versus average menarche (odds ratio 1.37, 95% confidence interval 1.09–1.72). Conclusion Sexual minority girls have a younger age at menarche than heterosexual girls and may benefit from screening for adverse outcomes associated with early menarche.

Purpose Adolescents with anorexia nervosa (AN) have decreased dehydroepiandrosterone (DHEA) and estrogen concentrations that may contribute to skeletal deficits. We sought to determine whether DHEA + estrogen replacement (ERT) prevented bone loss in young adolescents with AN. Methods We recruited females with AN (n = 70, ages 11–18 years) into a 12-month, randomized, double-blind placebo-controlled trial. Participants were randomized to oral micronized DHEA 50 mg + 20 mcg ethinyl estradiol/.1 mg levonorgestrel daily (n = 35) or placebo (n = 35). Outcomes included serial measures of bone mineral density (BMD) by dual-energy X-ray absorptiometry (total body, hip, spine) and peripheral quantitative computed tomography (pQCT; tibia). Magnetic resonance imaging of T1-weighted images of the left knee determined physeal status (open/closed). Results Sixty-two subjects completed the trial. Physeal closure status was the strongest predictor of aBMD changes. Among girls with open physes, those who received DHEA + ERT showed a decline in BMD Z-scores compared with those receiving placebo, whereas there was no effect in those with at least one closed physis. Treatment did not affect any pQCT measures, regardless of physeal closure status. Conclusions Combined DHEA + ERT did not significantly improve dual-energy X-ray absorptiometry or pQCT BMD measurements in young adolescent girls with AN, in contrast to an earlier trial showing benefit in older adolescents and young women. In girls with open physes, the mean change in the placebo arm was greater than that of the DHEA + ERT group. We conclude that DHEA + ERT is ineffective for preserving bone health in growing young adolescents with AN at the dose and route of administration described in this report.

PROBLEM Associations between immune dysfunction conditions (eg, systemic lupus erythematous, rheumatoid arthritis) and endometriosis have been observed in adult women, but not assessed among a younger population. We investigated the association between immune-mediated conditions and endometriosis among young women. METHOD OF STUDY This cross-sectional analysis in the Women's Health Study: From Adolescence to Adulthood included 551 participants with surgically diagnosed endometriosis (median age=19) and 652 controls without endometriosis (median age=24). Participants completed an expanded Endometriosis Phenome and Biobanking Harmonization Project questionnaire. We used logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) to investigate the associations between autoimmune/inflammatory, atopic, chronic pain/fatigue, and endocrine disorders with endometriosis, adjusting for confounders. RESULTS Participants with any autoimmune and/or inflammatory condition had an increased odds of co-occurring endometriosis (OR: 1.87; CI: 0.92-3.80), as did participants with allergies (OR: 1.76; CI: 1.32-2.36), asthma (OR: 1.35; CI: 0.97-1.88), chronic fatigue syndrome and/or fibromyalgia (OR: 5.81; CI: 1.89-17.9), or previous mononucleosis (OR: 1.75; CI: 1.14-2.68). Odds of endometriosis were lower among participants with eczema (OR: 0.68; CI: 0.44-1.04). We observed a positive trend between the number of immune-mediated conditions and the odds of endometriosis (p-trend=0.0002). Endocrine disorders were not associated with endometriosis. CONCLUSIONS Among this population of adolescents and adult women, endometriosis was more likely among participants with autoimmune and/or inflammatory diseases, allergies, asthma, previous mononucleosis infection, and chronic fatigue and/or fibromyalgia. We observed that an increasing number of immune-mediated conditions were positively associated with endometriosis risk. It is important for clinicians who care for adolescents and women with these conditions to consider endometriosis as a comorbidity.

Background:. Progestin-only contraception has become increasingly popular among adolescents. However, patients, parents, and providers share concerns regarding the potential impact that progestin-only contraception may have on breast growth. We sought to explore the impact of progestin-only contraception on breast hypertrophy and symptomatology in adolescents with macromastia. Methods:. Patients between the ages of 12 and 21 years undergoing reduction mammaplasty were prospectively assessed for baseline and postoperative breast symptomatology and medication use. The medical records of female controls within the same age range were retrospectively reviewed. Results:. A total of 378 participants with macromastia and 378 controls were included in analyses. A higher proportion of controls used progestin-only methods compared with participants with macromastia (28.0% versus 5.3%, P < 0.001). The most commonly prescribed methods were the depot medroxyprogesterone acetate injection (31.0%), levonorgestrel-containing intrauterine device (31.0%), and subdermal implant (26.2%). Patients with macromastia who used progestin-only contraception had a greater amount of breast tissue resected during reduction mammaplasty (P = 0.04), reported greater musculoskeletal pain (P = 0.008), and were roughly 500% more likely to experience breast pain (odds ratio, 4.94; 95% confidence interval, 1.58–15.47; P = 0.005) than those with macromastia who never used hormonal contraception. Conclusions:. Adolescents with macromastia who use progestin-only contraception may have greater breast hypertrophy and worse breast and musculoskeletal pain. When appropriate, providers may wish to consider other contraception methods for patients who are at-risk for breast hypertrophy or those who suffer from macromastia-related symptoms.

Endometriosis is generally histopathologically defined as the presence of at least 2 of the following: endometrial stroma, Mullerian epithelium, and/or hemosiderin-laden macrophages (HLM). Despite clinically evident endometriotic lesions, biopsies are frequently nondiagnostic. In this study, we conducted a large-scale review of biopsies of lesions clinically thought to represent endometriosis and correlate the histologic findings with clinical appearance to expand sensitivity of the pathologic definition of endometriosis, particularly in patients on hormonal therapy. In all, 112 biopsies from 78 patients (mean age=25, range 18-39 yr) were reviewed for histopathologic features suggestive of or diagnostic for endometriosis including the presence of endometrial stroma, Mullerian epithelium, dystrophic calcifications, HLM, chronic inflammation, adhesions, and vascular proliferation. Endometriosis was confirmed by pathologic criteria in 37 of 78 patients (47%). Biopsies from patients on hormonal therapy (n=62, 80%) were significantly less likely to meet pathologic criteria for endometriosis (P=0.01). Nondiagnostic biopsies (70/112; 63%) frequently displayed HLM (20%), chronic inflammation (29%), dystrophic calcifications (26%), vascular proliferation (20%), or adhesions (20%) and were significantly more likely to have a vascular clinical appearance (P=0.01). Diagnostic biopsies (42/112; 38%) were more likely to have a blue/black clinical appearance (P=0.03), demonstrate HLM (P=0.004), and display pseudodecidualization (P=0.05). Patients with a high clinical suspicion of endometriosis have a range of histologic findings, with less than half meeting the current histopathologic criteria for diagnosing endometriosis. Given the heterogeneous histopathologic appearance, revision of the histologic criteria may be warranted with further exploration, particularly for lesions with predominantly vascular features.

Background Reduction mammaplasty effectively alleviates symptoms and restores quality of life. However, operating on adolescents remains controversial, partly because of fear of potential postoperative breast growth. This cross-sectional study provides surgeons with a method to predict the optimal timing, or biological "sweet spot," for reduction mammaplasty to minimize the risk of breast regrowth in adolescents. Methods The authors reviewed the medical records of women aged 12 to 21 years who underwent reduction mammaplasty from 2007 to 2019. Collected data included symptomology, perioperative details, and postoperative outcomes. Results Four hundred eighty-one subjects were included in analyses and were, on average, 11.9 years old at first menses (menarche) and 17.9 years old at surgery. Six percent of subjects experienced postoperative breast growth. Breast size appears to stabilize considerably later in obese adolescents compared to healthy-weight and overweight patients, and breast growth in obese macromastia patients may not end until 9 years after menarche. Operating on obese women before this time point increased the likelihood of glandular breast regrowth by almost 120 percent (OR, 1.18; 95 percent CI, 1.11 to 1.26). Surgery performed less than 3 years after menarche, the commonly regarded end of puberty, increased the likelihood of glandular regrowth by over 700 percent in healthy-weight and overweight subjects (OR, 7.43; 95 percent CI, 1.37 to 40.41). Conclusions Findings suggest that reduction mammaplasty age restrictions imposed by care providers and third-party payors may be arbitrary. Surgical readiness should be determined on an individual basis incorporating the patient's biological and psychological maturity, obesity status, potential for postoperative benefit, and risk tolerance for postoperative breast growth. Clinical question/level of evidence Risk, III.

Objectives To examine contraceptive methods used by adolescent/young adult women of diverse sexual orientations. Study design We collected data from 12,902 females, born 1982–1995, from the longitudinal Growing Up Today Study. Results Compared to heterosexuals, lesbians were half as likely to use contraceptives; other sexual minority subgroups (e.g., bisexuals) were more likely to use contraceptives, particularly long-acting reversible contraceptives. Conclusions Many sexual minority women use contraception throughout adolescence/young adulthood, though use is low among lesbians. Implications With limited contraception use, lesbians miss opportunities for care and need to be brought into the healthcare system in other ways.

Purpose Despite the psychosocial deficits associated with gynecomastia, surgical treatment of adolescent gynecomastia remains controversial. This longitudinal cohort study measures changes in health-related quality of life following surgical treatment of gynecomastia in adolescents. Methods The following surveys were administered to adolescents with gynecomastia and male controls, aged 12–21 years: Short-Form 36v2 (SF-36), Rosenberg Self-Esteem Scale (RSES), and Eating-Attitudes Test-26. Subjects completed surveys at baseline and postoperatively/at follow-up at 6 months, 1 year, 3 years, and 5 years. Results From 2008 to 2017, 44 patients undergoing surgical treatment of gynecomastia and 64 unaffected male controls participated in our study. At baseline, gynecomastia patients scored significantly worse than controls on the RSES and in five SF-36 domains: general health, vitality, social functioning, role-emotional, and mental health. Scores significantly improved postoperatively on the RSES, and in four SF-36 domains: physical functioning, role-physical, bodily pain, and social functioning. Postoperatively, gynecomastia subjects scored similarly to controls in all SF-36 domains and the RSES. Young and overweight/obese patients and those with severe gynecomastia had the greatest postoperative improvement across survey measures. Conclusions Surgical treatment of gynecomastia significantly improves the quality of life of adolescents, with measurable improvements in physical and psychosocial functioning. Postoperatively, gynecomastia patients performed comparably to unaffected controls. Surgical treatment of gynecomastia in adolescents and young men has the potential to significantly improve quality of life, particularly in younger and overweight/obese patients and those with moderate to severe gynecomastia. Concerns regarding patient age and body mass index alone should not contraindicate surgery.

Purpose of review Polycystic ovarian syndrome (PCOS) is a common endocrinopathy which can be difficult to treat in adolescents. Fortunately, early identification and treatment can help mitigate some of the metabolic complications. In this review, we reflect on recent literature regarding PCOS diagnosis, associated complications, and treatment options. Recent findings Although there are three well known criteria to diagnose PCOS, they can be difficult to translate to adolescence. Newer diagnostic tools under study include anti-Mullerian hormone and revised ultrasound criteria. More is known about the many complications associated with PCOS, and new treatment options are on the horizon. Summary PCOS frequently will present during adolescence. These young women may already have symptoms of metabolic comorbidities. Providers caring for these patients must be aware of the many related complications and common treatment options. Newer diagnostic techniques and treatment options are under active study in adults, and may soon be translated to adolescence. A comprehensive approach allows treatment of patients' concerns, and also prevention of metabolic complications.

Objective To determine the prevalence and experience of migraines in adolescents with surgically confirmed endometriosis compared with those without endometriosis. Design Cross-sectional study conducted within The Women's Health Study: From Adolescence to Adulthood—an ongoing longitudinal cohort. Setting Boston Center for Endometriosis. Patient(s) Adolescent females enrolled November 2012 through November 2016. The case group included adolescents surgically diagnosed with endometriosis. The control group included adolescents without endometriosis, recruited from the local community and clinics. Intervention(s) Not available. Main Outcome Measure(s) An extensive online health questionnaire regarding medical history, lifestyle, medication use, anthropometrics, and symptom experience and treatments. Migraine diagnosis was self-reported. Migraine pain and noncyclic pelvic pain severity were rated using an 11-point numerical rating scale. Cyclic pelvic pain was categorized. Result(s) Adolescents with endometriosis were more likely to experience migraines (69.3%) than those without endometriosis (30.7%) (multivariable odds ratio=4.77, 95% confidence interval 2.53, 9.02). For each 1-point increase in the migraine numerical rating scale, the odds of endometriosis increased by 22% (multivariable odds ratio=1.22, 95% confidence interval 1.03, 1.44; P trend = .02). Among those with endometriosis, age of menarche was associated inversely with the odds of migraines. Participants with endometriosis and migraines have more dysmenorrhea than those without migraines. Conclusion(s) Adolescents with endometriosis are more likely to experience migraines than adolescents without endometriosis. A linear relationship exists between migraine pain severity and the odds of endometriosis, suggesting heightened pain sensitivity for adolescents with endometriosis. Due to the strong correlation, patients who present with either condition should be screened for comorbidity to maximize the benefits of care.

Adolescent reduction mammaplasty remains controversial because of concerns of postoperative breast growth, complications, and the effect on well-being. The authors sought to prospectively quantify early and late complications following reduction mammaplasty in adolescents and young women, and examine the intersection of surgical complications and postoperative health-related quality of life.From 2008 to 2017, female patients aged 12 to 21 years undergoing reduction mammaplasty were asked to complete the 36-Item Short-Form Health Survey (version 2), the Rosenberg Self-Esteem Scale, the Breast-Related Symptoms Questionnaire, and the Eating-Attitudes Test-26 preoperatively and postoperatively at 6 months and 1, 3, 5, and 7 years. Clinical evaluations using standardized forms assessed baseline and postoperative symptomatology, complications, and surgical outcomes.In the authors' sample of 512 participants, the most common complications included hypertrophic scarring (20.0 percent) and altered sensation of the nipple (8.4 percent) or breast (7.8 percent). Patient age, body mass index category, and amount of tissue resected did not significantly increase the odds of developing a complication. Significant postoperative improvements on the Rosenberg Self-Esteem Scale, the Breast-Related Symptoms Questionnaire, the Eating-Attitudes Test-26, and in all 36-Item Short-Form Health Survey domains (i.e., physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health) were largely seen irrespective of whether complications occurred.Although complications following reduction mammaplasty were common, the vast majority were minor. Patients had significant postoperative improvements in their physical and psychosocial well-being regardless of whether they experienced a complication. Concerns for potential complication, especially in younger and overweight or obese patients, should not preclude otherwise healthy adolescents and young women from the benefits of reduction mammaplasty.Therapeutic, IV.

Debilitating abdominal and pelvic pain conditions are highly prevalent in adults and adolescents. Assessing sensory functioning among people with painful conditions is important in understanding the disease. Reference values for Quantitative Sensory Testing (QST), used to assess sensory perception, are well established for other regions but not the abdomen. The aim of this study was to establish QST reference values for the abdomen in a diverse group of males and female adults and adolescents. In this cross-sectional study, 181 healthy, pain-free males and females from age 12-50 years completed a comprehensive QST battery in upper and lower abdomen and a control site. The QST battery consisted of: Dynamic Mechanical Touch (DMT), Light Touch Detection (LTD), Sharp Prick Detection (SPD), Pressure Pain Threshold (PPT), Temporal Summation of Pain (TSP), Cool and Warmth Detection Thresholds (CDT, WDT), and Cold and Heat Pain Thresholds (CPT, HPT). Participants also answered pain-related questionnaires including the Pain Catastrophizing Scale, 36-Item Short Form Survey, Pain Sensitivity Questionnaire (PSQ). Mean and standard deviation values were calculated for each QST sub-test and separated by age, sex, and body site (upper and lower abdomen, and control site). Results of RMANOVAs indicated that pain sensitivity differed by site and modality, with no consistent pattern indicating one area was generally more sensitive than others. There were also effects of sex with males experienced less sensitivity to pressure and cold pain than females. Self-reported pain sensitivity (PSQ) was associated with greater abdominal sensitivity to punctate, cold, and heat pain. This paper successfully established reference QST values for the upper and lower abdominal sites for healthy, pain-free male and female adolescents and adults which will be critical in understanding somatosensory nervous system function among patients with abdominal and pelvic pain. These data will be critical in understanding nociceptive processing in the abdominal region.

Background Abnormal uterine bleeding (AUB) is commonly experienced by adolescents and young adults (AYA) following contraceptive implant placement. We assessed for predictors of AUB, factors contributing to AUB management, and differences in implant continuation rates by AUB management approach. Methods We analyzed data from a long-acting reversible contraception database from 3 AYA sites in tertiary care institutions. We included patients with the contraceptive implant placed from 7/1/2014-12/31/2018 and follow-up data through 12/31/2019. We excluded patients with ≥3 years since insertion without follow-up. Variables included age at insertion, comorbid conditions, menstrual history, prior contraceptive use, patient-reported AUB after implant placement, AUB evaluation and management, and implant discontinuation. We included data from insertion, follow-up, and removal visits. We assessed AUB predictors with logistic regression. Descriptive statistics, chi-square, and t-tests compared patient demographic and clinical variables by AUB status. Survival analysis examined predictors of time to discontinuation. This study was IRB approved. Results Our sample included 609 patients, average age was 19 years (SD=2.5). Prior to implant placement 37% reported irregular menses, and after insertion 25% reported AUB. In those with AUB, 67% had evaluation and management including laboratory studies (32%), pelvic ultrasound (4%), or medication therapy (86%). Medication initiation occurred at first AUB report for the majority of patients. Of those prescribed a medication, 60% received a combined oral contraceptive or progestin-only pill. AUB was associated with polycystic ovary syndrome (PCOS) in bivariate analysis (p-value=0.006), 57% of patients with PCOS (n=14) reported AUB after implant insertion. This association persisted after adjusting for age, medical comorbidities, menstrual history, and prior contraceptive use. Bivariate analyses did not identify any predictors for AUB evaluation and management. Implant discontinuation was low: 16% at 1 year, 27% at 2 years, and 35% at 3 years. Early discontinuation was significantly different between patients with and without AUB: 21% vs. 14% at 1 year (p-value=0.047), 38% vs. 23% at 2 years (p-value=0.000), 44% vs. 31% at 3 years (p-value=0.007). Medication for AUB management did not impact rates of or time to early discontinuation. Conclusions In this large cohort of AYA, PCOS was the only significant predictor of implant-associated AUB. There were no relationships between AUB and comorbid medical conditions or prior contraceptive use. There were no significant predictors of AUB evaluation and management following implant insertion, and such evaluation and management did not impact rates of early discontinuation.

Background & Aims Gastroenterologic symptoms often are reported by adults with endometriosis, leading to unnecessary diagnostic tests or complicated treatment. We investigated associations between endometriosis and irritable bowel syndrome (IBS) in adolescents and whether concurrent pain disorders affect these. Methods We collected data from within The Women’s Health Study: Adolescence to Adulthood, which is a US longitudinal study of premenopausal females with and without endometriosis. Our study cohort included participants younger than 21 years enrolled from 2012 to 2018. Participants completed an extensive health questionnaire. Those with IBS based on a self-reported diagnosis or meeting Rome IV diagnostic criteria were considered cases and those without IBS were controls. Subjects without concurrent gastrointestinal disorders or missing pain data (n = 323) were included in the analyses. We calculated adjusted odds ratios using unconditional logistic regression. Results More adolescents with endometriosis (54 of 224; 24%) had comorbid IBS compared with adolescents without endometriosis (7 of 99; 7.1%). The odds of IBS was 5.26-fold higher among participants with endometriosis than without (95% CI, 2.13–13.0). In girls with severe acyclic pelvic pain, the odds of IBS was 35.7-fold higher in girls without endometriosis (95% CI, 4.67–272.6) and 12-fold higher in girls with endometriosis (95% CI, 4.2–36.3), compared with no/mild pain. For participants with endometriosis, each 1-point increase in acyclic pain severity increased the odds of IBS by 31% (adjusted odds ratio, 1.31; 95% CI, 1.18–1.47). Conclusions In an analysis of data from a longitudinal study of girls and women with and without endometriosis, we found significant associations between endometriosis and IBS, and a linear relationship between acyclic pelvic pain severity and the odds of IBS. Increased provider awareness and screening for IBS and endometriosis will improve patient outcomes and increase our understanding of these complex disorders.

We sought to determine whether low-magnitude mechanical stimulation (LMMS) normalizes bone turnover among adolescents hospitalized for anorexia nervosa (AN). Brief, daily LMMS prevents the decline in bone turnover typically seen during bed rest in AN. LMMS may have application for patients with AN in the inpatient setting to protect bone health. Malnourished adolescents with AN requiring medical hospitalization are at high risk for rapid reduction in skeletal quality. Even short-term bed rest can suppress normal patterns of bone turnover. We sought to determine whether LMMS normalizes bone turnover among adolescents hospitalized for complications of AN. In this randomized, double-blind trial, we prospectively enrolled adolescent females (n = 41) with AN, age 16.3 ± 1.9 years (mean ± SD) and BMI 15.6 ± 1.7 kg/m2. Participants were randomized to stand on a platform delivering LMMS (0.3 g at 32-37 Hz) or placebo platform for 10 min/day for 5 days. Serum markers of bone formation [bone-specific alkaline phosphatase (BSAP)], turnover [osteocalcin (OC)], and bone resorption [serum C-telopeptides (CTx)] were measured. From a random coefficients model, we constructed estimates and confidence intervals for all outcomes. BSAP decreased by 2.8% per day in the placebo arm (p = 0.03) but remained stable in the LMMS group (p = 0.51, pdiff = 0.04). CTx did not change with placebo (p = 0.56) but increased in the LMMS arm (+6.2% per day, p = 0.04; pdiff = 0.01). Serum OC did not change in either group (p > 0.70). Bed rest during hospitalization for patients with AN is associated with a suppression of bone turnover, which may contribute to diminished bone quality. Brief, daily LMMS prevents a decline in bone turnover during bed rest in AN. Protocols prescribing strict bed rest may not be appropriate for protecting bone health for these patients. LMMS may have application for these patients in the inpatient setting.

We conducted the first comparison of dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) outcomes in adolescent girls with anorexia nervosa. We observed deficits in bone density by both tools. pQCT assessments were associated with many of the same clinical parameters as have been previously established for DXA. Adolescents with anorexia nervosa (AN) commonly exhibit bone loss, but effects on bone geometry are less clear. We compared measures obtained by DXA and pQCT in girls with AN. Seventy females (age 15.5 ± 1.9 years ) with AN and 132 normal-weighted controls underwent tibial measures by pQCT including trabecular volumetric bone mineral density (vBMD) at the 3 % site, cortical vBMD and dimensions at the 38 % site, and muscle cross-sectional area (CSA) at the 66 % site. Participants with AN also underwent standard DXA measures. Independent t tests compared the pQCT results, while Pearson coefficient assessed correlations among DXA and pQCT measures. Trabecular vBMD Z-scores were lower in AN compared to controls (AN −0.31 ± 1.42 vs +0.11 ± 1.01, p = 0.01) and cortical vBMD Z-scores were higher (AN +0.18 ± 0.92 vs −0.50 ± 0.88, p
