Parenting Stress, Community Support, and Unmet Health Care Needs of Children in the US.

OBJECTIVES: In 2018, approximately 2.3 million children in the United States had unmet healthcare needs (UHCN). To date, studies examining associations between UHCN and parent stress and support have had limited generalizability. This study aimed to investigate the relationship between children's UHCN and parenting stress and support using a nationally representative sample. Additionally, this study aimed to assess associations between unmet mental health needs and these parental well-being measures. METHODS: Households with children ages 0-17 and complete data on UHCN in the combined 2016, 2017, 2018, and 2019 cohorts of the National Survey of Children's Health (NSCH) met inclusion criteria. Logistic regressions were used to evaluate associations between overall UHCN and outcome measures of parental coping, aggravation, emotional support, and neighborhood support. Associations between mental UHCN and these outcome measures were analyzed in a subset limited to children with mental health conditions. Regressions were adjusted for potential confounders, including demographics, household income, medical home status, and health insurance (adequacy/type). RESULTS: In our sample of 131,299 children, overall UHCN were associated with poorer parental coping (aOR = 5.35, 95% CI: [3.60, 7.95]), greater parental aggravation (aOR = 3.35, 95% CI: [2.73, 4.12]), and non-supportive neighborhood (aOR = 2.22, 95% CI: [1.86, 2.65]). Mental UHCN were similarly associated with parental coping and aggravation and neighborhood support in the mental health subset. CONCLUSIONS FOR PRACTICE: Healthcare professionals must address the needs of children with UHCN and collaborate with community organizations and child advocates to promote coordinated and comprehensive care and adequately support caregivers.

Providing a post-vasectomy semen analysis cup at the time of vasectomy rather than post-operatively improves compliance.

Background: Post-vasectomy semen analysis (PVSA) completion rates after vasectomy are poor, and minimizing the need for an additional in-person visit may improve compliance. We hypothesized that providing PVSA specimen cup at time of vasectomy instead of at a postoperative appointment might be associated with higher PVSA completion rates. Methods: We performed a retrospective cohort study with historical control using medical records of all patients seen by a single provider for vasectomy consultation between October 2016 and June 2022. All patients who underwent vasectomy were included. Patients who underwent vasectomy prior to 05/01/2020 had PVSA specimen cup given at postoperative appointment two weeks following vasectomy, and those who underwent vasectomy after 05/01/2020 were given PVSA specimen cup at time of vasectomy. PVSA completion, demographic, and clinical outcomes data were collected. Logistic regressions were used to investigate associations between PVSA completion rates and timing of PVSA specimen cup provision. Results: There were no significant differences among study cohorts across all patient demographics analyzed, including age, body mass index (BMI), age of primary partner, presence of children, and history of prior genitourinary infection. A total of 491 patients were seen for vasectomy consultation between October 2016 and June 2022; among these patients, 370 underwent vasectomy. Of these, 173 (46.8%) patients underwent vasectomy prior to 05/01/2020 and were given PVSA specimen cup at postoperative visit; 197 (53.2%) patients underwent vasectomy after 05/01/2020 and were given PVSA specimen cup at vasectomy. Providing PVSA specimen cup at time of vasectomy was associated with higher odds of PVSA completion than providing PVSA specimen cup at postoperative visit [62.4% vs. 49.7%; odds ratio (OR) =1.68; 95% confidence interval (CI): 1.11, 2.55]. Adjusting for all identified confounders excludes 35 (9.5%) patients without a primary partner and shows no statistically significant association in cup timing [adjusted OR (aOR) =1.53; 95% CI: 0.98, 2.39]. Adjusting for all identified confounders except age of primary partner revealed timing of specimen cup provision at time of vasectomy was associated with higher odds of PVSA completion (aOR =1.64; 95% CI: 1.08, 2.52). Conclusions: PVSA specimen cup provision at time of vasectomy versus at postoperative appointment is associated with higher rates of PVSA completion in this retrospective cohort study.

Patient-reported prostate cancer treatment regret following primary partial gland cryoablation.

BACKGROUND: Prostate cancer treatment-related regret (TRR) incorporates the myriad effects of diagnosis and treatment with associated behavioral, emotional, and interpersonal changes within the context of patient values and expectations. We aimed to investigate TRR following primary partial gland cryoablation (PPGCA). METHODS: Men with prostate cancer undergoing PPGCA since 3/2017 enrolled in a prospective outcome registry. Between June and August 2022, a validated prostate cancer related TRR decision scale was distributed. TRR score ≥40 was considered significant TRR. Men were considered potent if they reported ability to have penetration at least half the time sexual intercourse was initiated. Associations between significant TRR and baseline characteristics and longitudinal outcomes were assessed using logistic regressions. RESULTS: Of 245 men who met inclusion criteria, 163 (67%) completed the survey with median time since cryoablation 2.3 years (IQR: 1.3, 3.6). Overall, the mean composite TRR score was 12.4/100. Significant TRR was expressed by 14% of men. Among those who were potent/had erectile function at baseline, loss of potency and erectile function were associated with higher probability of significant TRR, respectively. No associations were identified between TRR and recurrence of clinically significant prostate cancer or salvage treatment. CONCLUSIONS: The overwhelming majority of men do not express TRR following PPGCA. The loss of potency or development of erectile dysfunction predisposes to TRR. It is imperative to elucidate short-, intermediate- and long-term functional and oncological outcomes in order to define factors associated with TRR to improve counseling and reduce patient regret.

Comparison of ChatGPT and Traditional Patient Education Materials for Men's Health.

INTRODUCTION: ChatGPT is an artificial intelligence platform available to patients seeking medical advice. Traditionally, urology patients consulted official provider-created materials, particularly the Urology Care Foundation™ (UCF). Today, men increasingly go online due to the rising costs of health care and the stigma surrounding sexual health. Online health information is largely inaccessible to laypersons as it exceeds the recommended American sixth to eighth grade reading level. We conducted a comparative assessment of patient education materials generated by ChatGPT vs UCF regarding men's health conditions. METHODS: All 6 UCF men's health resources were identified. ChatGPT responses were generated using patient questions obtained from UCF. Adjusted ChatGPT responses were generated by prompting, "Explain it to me like I am in sixth grade." Textual analysis was performed using sentence, word, syllable, and complex word count. Six validated formulae were used for readability analysis. Two physicians independently scored responses for accuracy, comprehensiveness, and understandability. Statistical analysis involved Wilcoxon matched-pairs test. RESULTS: ChatGPT responses were longer and more complex. Both UCF and ChatGPT failed official readability standards, although ChatGPT performed significantly worse across all 6 topics (all P < .001). Conversely, adjusted ChatGPT readability typically surpassed UCF, even meeting the recommended level for 2 topics. Qualitatively, UCF and ChatGPT had comparable accuracy, although ChatGPT had better comprehensiveness and worse understandability. CONCLUSIONS: When comparing readability, ChatGPT-generated education is less accessible than provider-written content, although neither meets the recommended level. Our analysis indicates that specific artificial intelligence prompts can simplify educational materials to meet national standards and accommodate individual literacy.

No Detectable Association Between Virtual Setting for Vasectomy Consultation and Vasectomy Completion Rate.

INTRODUCTION: The COVID-19 pandemic has fueled widespread incorporation of telehealth into urology practices. Vasectomy consultation via telehealth is convenient and improves access to care for male contraception. However, it does not allow for physical examination, inherently leading to possible day-of-procedure cancellations due to unforeseen anatomic concerns. This study aimed to compare vasectomy completion rates between patients undergoing virtual vs in-person consultation. METHODS: All patients seen by a single provider at NYU Langone Health for vasectomy consultation between October 2016 and June 2022 were included in the study. Most patients seen before March 2020 had in-person consultations, whereas the majority of patients seen afterwards had virtual consultations without option for in-person visit due to the emergence of COVID-19. All patients seen virtually were examined in a consult room prior to being prepped for the vasectomy in the procedure room. Visit type, demographic information, and clinical outcomes data were collected for all patients. A chi-square test was used to compare the rate of vasectomy completion between those with in-person and virtual consultation. Analysis was performed using R, version 4.0.5. RESULTS: Four hundred ninety-one patients were seen by a single provider for vasectomy consultation between October 2016 and June 2022. One hundred ninety-seven (40.1%) consultations were performed virtually and 294 (59.9%) consultations were performed in person. Three hundred seventy (75.4%) of all patients seen for consultation (both virtual and in person) ultimately underwent vasectomy. There was no evidence of difference in rate of completing vasectomy after virtual (75.6%) and in-person (75.2%) consultation (P = .91). Two of the 197 (1%) patients who consulted virtually had their vasectomy procedures cancelled on the day of the procedure based on their preoperative exam; one because of abnormal epididymal sensitivity after prior scrotal infection, the other because of a history of orchiopexy that the patient was not aware of until the surgeon started inquiring about scrotal scars present. CONCLUSIONS: Despite the lack of physical examination, virtual vasectomy consultation is both feasible and effective, with rates of vasectomy completion comparable to traditional in-person consultation.

Biopsy Assessment of Oncologic Control 3 Years Following Primary Partial Gland Cryoablation: A Prospective Cohort Study of Men With Intermediate-risk Prostate Cancer.

PURPOSE: We evaluated 3-year oncologic outcomes following primary partial gland cryoablation. MATERIALS AND METHODS: Men with unilateral intermediate-risk prostate cancer undergoing primary partial gland cryoablation since March 2017 enrolled in a prospective outcome registry. The postablation protocol for all men included surveillance prostate biopsy at 2 years postablation and reflex prostate biopsy for cases with high suspicion of recurrence (eg, progressive rise in PSA). Recurrence of clinically significant prostate cancer was defined as any Gleason grade group ≥2 disease on postablation biopsy. Freedom from failure represented no whole gland salvage treatment, metastatic prostate cancer, or prostate cancer mortality. Freedom from recurrence and freedom from failure were characterized using nonparametric maximum likelihood estimators. RESULTS: A total of 132 men had at least 24 months of follow-up data. Biopsies identified clinically significant prostate cancer in 12 men. At 36 months, model-estimated rates of freedom from recurrence of in-field, out-of-field, and overall clinically significant cancer were 97% (95% CI: 92-100), 87% (95% CI: 80-94), and 86% (95% CI: 78-93), respectively. The model-estimated proportion with freedom from failure at 36 months was 97% (95% CI: 93-100). CONCLUSIONS: The low in-field cancer detection rate at 3 years indicates successful ablation of localized cancers. Conversely, our observed out-of-field detection rate highlights the need for continued surveillance following partial gland cryoablation. Many of these recurrences exhibited very low volume of clinically significant disease below the detection threshold of multiparametric MRI, suggesting a limited role for multiparametric MRI in detecting clinically significant recurrences at 2 years. These findings emphasize the need for long-term surveillance and identification of predictors of clinically significant prostate cancer recurrences to guide biopsy timing.

Associations Between Bullying and Condition Severity Among Youth With Chronic Health Conditions.

PURPOSE: Children with chronic conditions are at increased risk of bullying involvement. In addition to examining associations between chronic health conditions and both victimization and perpetration, this study investigated whether condition severity is associated with bullying involvement. METHODS: A secondary analysis of the 2018-2019 National Survey of Children's Health was performed. Children ages six-17 (n = 42,716) were classified as perpetrators (if bullied others ≥one-two times/month), victims-only (if victimized ≥one-two times/month and not a perpetrator) or uninvolved in bullying (neither perpetrator nor victim-only). Survey-weighted multinomial logistic regressions were used to investigate associations between bullying involvement and 13 chronic medical and developmental/mental health conditions. For children with conditions associated with being a victim and/or perpetrator, multinomial logistic regressions were used to further investigate associations between condition severity and victimization or perpetration. RESULTS: All 13 conditions were associated with higher odds of victimization. Seven developmental/mental health conditions were associated with higher odds of perpetration. Condition severity was associated with at least one domain of bullying involvement for one chronic medical and six developmental/mental health conditions. Notably, among children with attention-deficit/hyperactivity disorder, learning disability, or anxiety, condition severity was associated with higher odds of being a victim or bully/bully-victim. DISCUSSION: Condition severity may be a risk-factor for bullying involvement for many developmental/mental health conditions. Future condition-specific analyses are needed that directly examine bullying involvement among children with varying severity of individual conditions like attention-deficit/hyperactivity disorder, learning disability, and anxiety, using a clear operational definition for bullying, objective measures of condition severity, and multiple informants of bullying involvement.

Keratinocyte Carcinoma Chemoprevention With a Combination of Imiquimod, 5-Fluorouracil, and Tretinoin.

BACKGROUND: The incidence of keratinocyte carcinomas (KCs), comprising basal and squamous cell carcinomas, is rising in the United States. Chemoprevention is one modality by which patients can reduce the incidence of KCs. METHODS: We performed a retrospective review of 327 patients who employed a combination of imiquimod 5% cream, 5-fluorouracil 2% solution, and tretinoin 0.1% cream in a field therapy regimen over the face/ears or scalp for chemoprevention. RESULTS: Patients had dramatically lower odds of having KCs in the treatment location (face/ears or scalp) in the one-year period after field treatment than in the one-year period preceding field treatment (OR=0.06, 95% CI: [0.02, 0.15]). Patients were also at lower odds of having KCs in non-treated areas the year after field treatment than in the year preceding it (OR=0.25, 95% CI: [0.14, 0.42]). Additionally, fewer cryotherapy sessions were performed for actinic keratoses in the treatment areas in the year after treatment (mean=1.5, SD=1.21) than the year preceding treatment (mean=2.3, SD=0.99; t=11.68, P<0.001). CONCLUSIONS: A combination of imiquimod 5% cream, 5-fluorouracil 2% solution, and tretinoin 0.1% cream were effective at reducing the incidence of new KCs for at least one year. Individualized treatment application frequency allowed for increased patient adherence. Prospective studies evaluating combination topical treatments for chemoprevention of KCs are needed to further assess the treatment effects found in this study.

Sports Team Participation and Vaping Among High School Students: 2015-2019.

BACKGROUND AND OBJECTIVES: Electronic vapor products (EVPs) have gained popularity among adolescents despite the health risks. This study aimed to evaluate whether sports team participation, a well-established protective factor against cigarette use, is similarly associated with decreased EVP use. METHODS: This cross-sectional study analyzed the 2015-2019 Youth Risk Behavior Survey cohorts. Survey-weighted logistic regressions investigated associations between sports team participation and past 30-day exclusive cigarette use, exclusive EVP use, and dual cigarette/EVP use among US high school students, adjusting for sex, grade, and survey year. RESULTS: The analytic cohort included 16 790 sports team participants (1.7% exclusive cigarette users, 18.3% exclusive EVP users, 5.5% dual users) and 13 972 nonparticipants (3.1% exclusive cigarette users, 13.4% exclusive EVP users, 7.6% dual users). Sports team participation was associated with lower odds of cigarette use (adjusted odds ratio [aOR], 0.58; 95% confidence interval [CI], 0.48-0.71) and dual use (aOR, 0.74; 95% CI, 0.63-0.88) and higher odds of EVP use (aOR, 1.39; 95% CI, 1.25-1.54). Among exclusive cigarette users and exclusive EVP users, sports team participation was associated with lower odds of frequent (≥20 days in the past month) than intermittent (1-19 days in the past month) cigarette use (aOR, 0.30; 95% CI, 0.19-0.49) and EVP use (aOR, 0.74; 95% CI, 0.61-0.91), respectively. CONCLUSIONS: Our findings suggest that risk profiles for cigarette and EVP use differ with respect to sports team participation. Given the health risks associated with EVP use, aggressive efforts must be taken to educate student athletes about the health risks of EVP use.

Smoking cessation pharmacotherapy use during index hospital admission following cystectomy for bladder cancer: A retrospective cohort study.

BACKGROUND: To identify gaps in urologic oncology quality and evidence-based smoking cessation care by assessing how often smoking cessation pharmacotherapy (SCP) is given in the inpatient setting following cystectomy. METHODS: The Premier Healthcare Database (PHD), a deidentified all-payer dataset, was used to generate nationally representative estimates of SCP receipt during hospitalization following cystectomy for patients with bladder cancer who smoke. Regressions were used to model associations between SCP receipt and patient- and hospital-level factors. RESULTS: Of the 21,624 patients who underwent cystectomy for bladder cancer, 3,676 patients (17.0%) were identified as current smokers, representing a weighted estimate of 16,063 admissions. Among these admissions, 27.9% of patients received SCP, the vast majority of which (91.5%) received exclusively nicotine replacement therapy. Rates of SCP receipt varied substantially across hospitals (median: 25.0%, IQR: 20.0-33.3, range: 0.0-60.0). Older age and black race (aOR = 0.59, 95% CI: 0.42-0.82) were associated with lower odds of SCP receipt. Increased patient comorbidity score was associated with higher odds of SCP receipt (aOR = 1.02, 95% CI: 1.01-1.03); specifically, chronic pulmonary disease, alcohol abuse, and depression were independently associated with SCP receipt. Hospital teaching status, bed capacity, and mean annual cystectomy volume were not associated with SCP receipt. SCP receipt was not associated with hospital length of stay nor 90-day readmission or mortality following cystectomy. CONCLUSIONS: SCP is infrequently given to patients who smoke during their hospitalization following cystectomy for bladder cancer, representing a gap in quality urologic oncology care and a missed opportunity to effectively intervene with evidence-based treatment.

Two Year Functional Outcomes Stratified According to Baseline Erectile Function Following Partial Gland Cryo-Ablation.

OBJECTIVE: To critically evaluate time dependent sexual function following primary partial gland cryo-ablation (PGCA) stratified according to baseline erectile function. METHODS: Between March 2017 and March 2022, all men undergoing primary PGCA by 2 surgeons were enrolled in an IRB approved outcomes registry. All subjects with PIRADS 2-5 lesion concordant with unilateral GGG 1-3 disease, no gross extra-prostatic extension on mpMRI, GGG >1 contralateral to the ROI, or distal apical disease on mpMRI were enrolled. Patients completed the Sexual Health Inventory for Men (SHIM) scale at baseline, 6, and 24 months. Men were stratified by baseline erectile function. Men with SHIM Score < 8 were excluded. Ability to sustain erection (aka "potency") was defined as a score of 3 or greater on question 2 of the SHIM index. Median SHIM scores and the proportion of men reporting "potency" at baseline, 6, and 24 months was recorded with comparisons between each timepoint. A univariate analysis was used to determine if clinical factors were associated with loss of "potency" at 24 months. RESULTS: 106 men met the inclusion criteria. There was a statistically significant decrease in the mean SHIM scores for the entire cohort between baseline to 6 months and baseline to 24 months. SHIM scores increased significantly for the total cohort between 6 and 24 months. "Potency" was preserved in 70% at 24 months. CONCLUSION: Those patients most likely to exhibit a decrease in sexual function have moderate ED at baseline. Only baseline ED was shown to predict preservation of "potency".

An antigen-targeting assay for Lyme disease: Combining aptamers and SERS to detect the OspA protein.

Lyme disease is the fastest growing vector-borne disease in the United States. However, current testing modalities are ill suited to detection of Lyme disease, leading to the diagnosis of many cases after treatment is effective. We present an improved, direct method Lyme disease diagnosis, where the Lyme specific biomarker Outer Surface Protein A (OspA) in clinical serum samples is identified using a diagnostic platform combining surface enhanced Raman scattering (SERS) and aptamers. Employing orthogonal projections to latent structures discriminant analysis, the system accurately identified 91% of serum samples from Lyme patients, and 96% of serum samples from symptomatic controls. In addition, the OspA limit-of-detection, determined to be 1 × 10-4 ng/mL, is greater than four orders of magnitude lower than that found in serum samples from early Lyme disease patients. The application of this platform to detect this difficult-to-diagnose disease suggests its potential for detecting other diseases that present similar difficulties.

Impact of Medication on Performance of Household Chores by Children with ADHD.

OBJECTIVE: To investigate associations between ADHD medication and household chore performance by children with ADHD. METHODS: A parent questionnaire collected information about the adequacy and quality of their child's performance of two self-care and six family-care chores. Parent perceptions of ADHD medication effect duration were used to identify children with after-school medication benefits (ASMB). Mann-Whitney U tests compared children with and without ASMB across measures of chore performance. RESULTS: A total of 565 parents of children with ADHD that regularly take medication completed the questionnaire. Children with ASMB were more likely to meet parental expectations for five of eight household chores and were more likely to be able to independently complete both self-care and family-care chores than those without ASMB. No differences were noted regarding their need for reminders or assistance with chores. CONCLUSION: Improvement in chore performance may be an additional consideration with respect to medication selection for children with ADHD.

School Readiness of Young Children Enrolled in Preschool in the United States.

OBJECTIVE: As preschool enrollment increases, it is important to know whether children enrolled in preschool are more likely to be "healthy and ready to learn (HRTL)." Our objective was to assess whether there are detectable school readiness differences between children enrolled in preschool and those who are not in a large, cross-sectional, nationally representative US sample. METHODS: Caregivers of 4931 3- to 4-year-old children in the 2016 National Survey of Children's Health indicated whether their child had started school and completed questions forming the "HRTL" School Readiness National Outcome Measure and its domains: early learning skills, self-regulation, social-emotional development, and physical health/motor development. Propensity score-matched logistic regression models estimated prevalence ratios (PRs) comparing children in versus not in preschool. RESULTS: 49.1% of children had started preschool. After matching, children in preschool did not differ from children not in preschool on the composite (PR = 1.21; 95% confidence interval [CI]: 0.92-1.58) or any domains. Children in preschool were more likely to be "on track" with rhyming words (PR = 1.48; 95% CI: 1.11-1.96), writing their name (PR = 2.36; 95% CI: 1.82-3.08), and holding a pencil (PR = 1.55; 95% CI: 1.12-2.14) but less likely with explaining things they have seen/done (PR = 0.59; 95% CI: 0.44-0.79) and overall health (PR = 0.57; 95% CI: 0.33-0.97). Some associations were sex specific. CONCLUSION: The largely null findings of this study underscore the need for further research that incorporates information regarding the extent and quality of preschool exposure when evaluating the developmental benefits of preschool on a national level.

Impact of ADHD on Household Chores.

Objective: To assess the relationship between ADHD and performance of household chores. Method: A 72-question online questionnaire was developed to collect demographic/clinical information as well as parents' assessment of their child's performance of self-care (SC) and family-care (FC) chores. Results: The sample consists of 797 primary caregivers of children with ADHD. The overwhelming majority of parents believed that ADHD to some extent affected their child's ability to independently and satisfactorily complete SC and FC chores. An inverse relationship was noted between parent ratings of a child's ability to do chores independently and satisfactorily and the likelihood they believed ADHD affected chore performance. There was no difference in chore performance between children with or without co-morbid oppositional defiant disorder. Conclusion: Given that household routines, including chores, play an important role in children's development and psychosocial adjustment, clinicians must be sensitive to the adverse impact that ADHD may have in this regard.

Breastfeeding Is Associated with a Reduced Risk of Attention-Deficit/Hyperactivity Disorder Among Preschool Children.

BACKGROUND: Breastfeeding has been associated with a lower risk of attention-deficit/hyperactivity disorder (ADHD). However, most studies examining this association have focused on small samples outside the United States or were likely subject to substantial residual confounding. Our objectives were to investigate, in a nationally representative sample of preschool children in the United States, the associations between ADHD and both age of breastfeeding cessation and age of formula introduction, as well as associations between ADHD and exclusive breastfeeding duration. METHODS: Analysis of data from children aged 3 to 5 years in the 2011/12 National Survey of Children's Health (n = 12,793). Logistic regressions were used to model current medical diagnosis of preschool ADHD as a function of breastfeeding duration, breastfeeding exclusivity, and the timing of formula introduction with adjustment for 12 potential confounders using propensity scores, including sex, age, race, household income, prematurity, insurance, and medical home. RESULTS: After adjustment for potential confounders, exclusive breastfeeding for at least 6 months was associated with substantially reduced odds of ADHD (adjusted prevalence odds ratio [aPOR] = 0.38; 95% confidence interval [CI], 0.15-0.99). Breastfeeding duration was also associated with ADHD, with 8% reduced odds of ADHD for each additional month of breastfeeding (aPOR = 0.92; 95% CI, 0.86-0.99). The results for exclusive breastfeeding duration were similar, but the confidence interval included the null (aPOR = 0.92; 95% CI, 0.85-1.00). The age of formula introduction was not associated with ADHD (aPOR = 0.92; 95% CI, 0.81-1.05). CONCLUSION: In a nationally representative sample of preschool children, breastfeeding was associated with a lower prevalence of ADHD. These findings provide evidence in support of the neurodevelopmental benefits of breastfeeding.

Sex Differences in Gender-Diverse Expressions and Identities among Youth with Autism Spectrum Disorder.

A growing body of evidence supports a potential link between autism spectrum disorder (ASD) and gender dysphoria, yet few studies have looked at sex differences in the co-occurrence of gender diversity and ASD. The aim of this study was to characterize sex differences in gender-diverse expressions and identities, as well as gender-related concerns, in youth with ASD. Parents of youth with ASD ages 6-21 (n = 163) completed an online questionnaire about their child's gender expression and identity. Sex-typed behaviors during childhood were measured using the Gender Identity Questionnaire (GIQ). Semi-partial Kendall correlations and chi-square tests were used to compare gender non-conformity, gender-diverse identities, and gender-related concerns between sexes. Sex-based differences in mean GIQ score and individual GIQ items were evaluated using a linear regression and semi-partial Kendall correlations, respectively. All regressions and correlations controlled for child age. Parents of girls were more likely to report child appearances and mannerisms that were less concordant with their child's birth sex. Based on parent-report, girls had lower mean GIQ scores, indicating greater cross-gendered/fewer same-gendered behaviors in childhood. Lastly, parents of girls with ASD were more likely to report that their daughters experienced anxiety due to gender-related concerns and discomfort during puberty than parents of boys. These findings suggest that girls with ASD seem more likely have gender-diverse preferences, mannerisms, and appearances that fall outside of traditional gender norms. Gender-related concerns appear to be a source of real distress in girls with ASD, highlighting the need for individualized support, especially during puberty. LAY SUMMARY: Despite evidence of a potential link between autism and gender diversity, few studies have explored differences in gender identity/expression between boys and girls with autism. Based on parent responses, we found that girls with autism are more likely than boys to have appearances and mannerisms, as well as behaviors during childhood, that fall outside of the traditional gender role. The unique profile of girls with autism and their elevated distress over gender-related concerns call for individualized support during adolescence.
