BackgroundThe ease of access to pornography has made its use common among adolescents. Although sexual and gender minority (SGM) (eg, gay, transgender) adolescents may be more prone to use pornography owing to sexual orientation–related information seeking and/or scarcity of potential romantic or sexual partners, relatively little attention has been paid to their pornography use and to the quantitative examination of the similarities and differences between heterosexual, cisgender (HC) and SGM adolescents’ pornography use characteristics.AimThe aim of the present study was to compare SGM and HC adolescents’ pornography use considering potential sex differences.MethodsWe used a sample of 2,846 adolescents (52.5% girls; Mage = 14.5 years, SD = 0.6), which was collected as part of an ongoing longitudinal study on adolescents’ sexual health. Data were analyzed with 5 groups: HC boys; HC girls; SGM boys; SGM girls; and SGM non-binary individuals.OutcomesAdolescents completed a self-report questionnaire about sexual and gender minority status and pornography use (ie, lifetime use, age at first exposure, and frequency of use in the past 3 months.)ResultsResults indicated significant differences between all groups: 88.2% of HC boys, 78.2% of SGM boys, 54.2% of SGM girls, 39.4% of HC girls, and 29.4% of SGM non-binary individuals reported having ever viewed pornography by the age of 14 years. SGM girls indicated a significantly younger age at first pornography use than HC girls, but this difference was not significant among boys. SGM boys reported the highest (median: many times per week), whereas HC girls reported the lowest (median: less than once a month) frequency of pornography use.Clinical TranslationResults suggest that SGM and HC boys' pornography use characteristics are rather similar, whereas SGM and HC girls’ pornography use patterns may be considered different presumably because of the varying underlying motivations (eg, using pornography to confirm sexual orientation).Strengths & LimitationsSelf-report measures and cross-sectional designs have potential biases that should be considered. However, the present study involved a large sample of adolescents including SGM adolescents, a population group that is understudied.ConclusionApproximately two-thirds of teenagers had gained their first experience with pornography in the present sample, and 52.2% reported using it once a week or more often in the past 3 months, indicating that pornography use may play an important role in both HC and SGM adolescents’ sexual development. Gender-based differences concerning pornography use seem to be robust regardless of SGM status.Bőthe B, Vaillancourt-Morel, MP, Girouard A, et al.

Concentrations of 18 metals and elements (MEs) in the gills, skin, muscle and liver of Carasobarbus luteus and Cyprinus carpio from the Atatürk Reservoir in Turkey were investigated. The results revealed that variations in the ME contents between fish species can be attributed to different diets. The highest contents of most MEs were recorded in the gills. Gender had no significant effect on the contents of most MEs in the tissues of fish species investigated. The relations between MEs in tissues and fish size were not clear and consistent. Health risk assessment methods indicated that consumption of the studied fish species is safe. It was estimated that daily consumption of 140 g of C. carpio or 170 g of C. luteus would not be expected to cause any health risks. Furthermore, it was found that fish species would provide significant benefits in terms of intake of essential MEs. 相似文献

BackgroundDiet and eating habits during youth have implications on diet and eating habits during adulthood, however, little longitudinal research has examined sexual orientation and gender expression differences in diet.ObjectiveOur aim was to examine sexual orientation and gender expression differences in diet quality and eating habits from adolescence to young adulthood.DesignData across multiple time points from the longitudinal Growing Up Today Study cohorts (1997 to 2011) were used.Participants/settingParticipants (n=12,880; aged 10 to 23 years) were the children of women from the Nurses’ Health Study II cohort.Main outcome measuresDiet quality scores were assessed using the Alternative Healthy Eating Index-2010. In addition, breakfast consumption (≥5 days/wk) and family dinners (≥5 days/wk) were assessed.Statistical analyses performedMultivariable generalized estimating equation regression models were fit to estimate sexual orientation and gender expression differences in diet quality scores, breakfast consumption, and family dinners, stratified by sex assigned at birth over available repeated measures.Results“Gender-nonconforming” males had significantly higher diet quality scores than “very gender-conforming” males (P<0.05). Diet quality scores did not differ by gender expression among females. “Mostly heterosexual” females and gay males had higher diet quality scores than their same-sex completely heterosexual counterparts (P<0.05). Adjustment for mother’s diet quality scores attenuated effects, except for gay males (P<0.05). “Gender-nonconforming” females were less likely to consume breakfast than “very gender-conforming” females (P<0.05). Similar results were found for “mostly heterosexual” and bisexual compared to completely heterosexual females. There were no gender expression or sexual orientation differences in family dinners among males and females.ConclusionsSexual orientation and gender expression have independent effects on diet quality scores and eating habits for both males and females. Very gender-conforming and completely heterosexual males had the lowest diet quality scores compared to other gender expression and sexual orientation groups. Additional research to explore the effects of sexual orientation and gender expression on diet-related health is needed to build upon these findings. 相似文献

Purpose
The primary aims of the study are to examine the rate of attempted fertility preservation (FP) among a Dutch cohort of transgirls who started gonadotropin-releasing hormone analog treatment and the reasons why adolescents did or did not choose to attempt FP.Methods
The study was a single-center retrospective review of medical records of 35 transgirls who started gonadotropin-releasing hormone analog treatment between 2011 and 2017.Results
Ninety-one percent of adolescents were counseled on the option of FP. Thirty-eight percent of counseled adolescents attempted FP, and 75% of them were able to cryopreserve sperm suitable for intrauterine insemination or intracytoplasmic sperm injection. Younger and Caucasian transgirls were less likely to attempt FP. No specific reason for declining FP was known in 33% adolescents, 32% of adolescents were not able to produce a semen sample because of early puberty, 17% felt uncomfortable with masturbation, 17% did not want to have children, and 13% wanted to adopt.Conclusions
One third of adolescents attempted FP, which is much more than the percentage reported in previous studies from the United States. One third of the transgirls could not make use of FP because they were unable to produce a semen sample because of early pubertal stage. For these adolescents, alternatives need to be explored. 相似文献95.

Mobility in sub-Saharan Africa links geographically-separate HIV epidemics, intensifies transmission by enabling higher-risk sexual behavior, and disrupts care. This population-based observational cohort study measured complex dimensions of mobility in rural Uganda and Kenya. Survey data were collected every 6 months beginning in 2016 from a random sample of 2308 adults in 12 communities across three regions, stratified by intervention arm, baseline residential stability and HIV status. Analyses were survey-weighted and stratified by sex, region, and HIV status. In this study, there were large differences in the forms and magnitude of mobility across regions, between men and women, and by HIV status.We found that adult migration varied widely by region, higher proportions of men than women migrated within the past one and five years, and men predominated across all but the most localized scales of migration: a higher proportion of women than men migrated within county of origin. Labor-related mobility was more common among men than women, while women were more likely to travel for non-labor reasons. Labor-related mobility was associated with HIV positive status for both men and women, adjusting for age and region, but the association was especially pronounced in women. The forms, drivers, and correlates of mobility in eastern Africa are complex and highly gendered. An in-depth understanding of mobility may help improve implementation and address gaps in the HIV prevention and care continua. 相似文献

Isolated patellofemoral arthritis is an increasingly recognized entity, and is usually associated with previous patellofemoral dysplasia or instability. Patellofemoral arthroplasty (PFA) has evolved significantly in recent years, both in terms of implant design and importantly in the understanding of appropriate patient selection. This review outlines the indications and investigations for PFA, provides a brief history of the development of contemporary implants, and presents the clinical outcomes for the prostheses most commonly used in the UK. In addition, it provides a detailed surgical technique for implantation of an onlay implant, with tips on how to optimize patellofemoral biomechanics and thus achieve a consistently good outcome. 相似文献

ObjectiveTo validate an artificial intelligence–augmented electrocardiogram (AI-ECG) algorithm for the detection of preclinical left ventricular systolic dysfunction (LVSD) in a large community-based cohort.MethodsWe identified a randomly selected community-based cohort of 2041 subjects age 45 years or older in Olmsted County, Minnesota. All participants underwent a study echocardiogram and ECG. We first assessed the performance of the AI-ECG to identify LVSD (ejection fraction ≤40%). After excluding participants with clinical heart failure, we further assessed the AI-ECG to detect preclinical LVSD among all patients (n=1996) and in a high-risk subgroup (n=1348). Next we modelled an imputed screening program for preclinical LVSD detection where a positive AI-ECG triggered an echocardiogram. Finally, we assessed the ability of the AI-ECG to predict future LVSD. Participants were enrolled between January 1, 1997, and September 30, 2000; and LVSD surveillance was performed for 10 years after enrollment.ResultsFor detection of LVSD in the total population (prevalence, 2.0%), the area under the receiver operating curve for AI-ECG was 0.97 (sensitivity, 90%; specificity, 92%); in the high-risk subgroup (prevalence 2.7%), the area under the curve was 0.97 (sensitivity, 92%; specificity, 93%). In an imputed screening program, identification of one preclinical LSVD case would require 88.3 AI-ECGs and 8.7 echocardiograms in the total population and 65.7 AI-ECGs and 5.5 echocardiograms in the high-risk subgroup. The unadjusted hazard ratio for a positive AI-ECG for incident LVSD over 10 years was 2.31 (95% CI, 1.32 to 4.05; P=.004).ConclusionArtificial intelligence–augmented ECG can identify preclinical LVSD in the community and warrants further study as a screening tool for preclinical LVSD. 相似文献

ObjetivoEl objetivo del estudio es describir la percepción de la calidad de vida relacionada con la salud de personas con depresión y comorbilidad física bajo una perspectiva de género. Se incluyeron 380 individuos mayores de 49 años con, al menos, una patología de las siguientes: diabetes, enfermedad obstructiva pulmonar crónica y cardiopatía isquémica, reclutadas en 31 equipos de atención primaria de Cataluña. La calidad de vida se midió con la escala EuroQol (EQ-5D). Además, se recogieron variables sociodemográficas, gravedad de depresión, índice de privación económica y ámbito de residencia. Se evaluó la relación ajustada entre el sexo y las dimensiones de calidad de vida, mediante una regresión logística multivariante.ResultadosEl 81,3% fueron mujeres; la media de edad fue de 68,4 años (DE: 8,8), La media de la escala visual analógica fue de 57,8 (DE: 17,4) en hombres y 55,8 (DE: 18,6) en mujeres. La media del EQ-Health Index fue de 0,74 (DE: 0,17) en hombres y 0,65 (DE: 0,21) en mujeres (p = 0,001). La probabilidad de presentar problemas en las dimensiones del EQ-5D mostró el sexo como factor de más peso (mujer = 1/hombre = 0) en: autocuidado OR: 2,29 (IC 95% 1,04 a 5,07) y actividades cotidianas OR: 3,09 (IC 95% 1,67 a 5,71). La movilidad se asoció con la edad OR: 1,87 (IC 95% 1,22 a 2,86), el ámbito de residencia con el dolor OR: 2,51 (IC 95% 1,18 a 5,34) y el Beck Depression Inventory (BDI) con la ansiedad/depresión OR: 4,77 (IC 95% 1,77 a 12,88).ConclusiónLa percepción en la calidad de vida de las mujeres con depresión y comorbilidad física es inferior a la de los hombres, siendo en ambos casos inferior a la de población general.Palabras clave: Calidad de vida, Depresión, Comorbilidad física, Género, Atención Primaria 相似文献
