The association between sexual orientation and eating disorders-related eating behaviours in adolescents: A systematic review and meta-analysis

Community norms of the Eating Pathology Symptoms Inventory (EPSI) in cisgender sexual minority adults

PURPOSE

Cisgender sexual minority adults are at elevated risk for eating disorders; however, community norms for certain eating disorder measures are lacking for this population. This study aimed to establish community norms for the Eating Pathology Symptom Inventory (EPSI) among cisgender gay, lesbian, bisexual + (individuals who identify as bisexual or pansexual; bi +) adults.

METHODS

Cross-sectional data were analyzed from 2062 cisgender participants-including 925 gay men, 573 lesbian women, 116 bi + men, and 448 bi + women-enrolled in The PRIDE Study, a national longitudinal cohort of sexual and gender minority adults in the United States. Participants completed the EPSI, and descriptive statistics were calculated for the eight EPSI scales.

RESULTS

We report mean scores, standard deviations, medians, interquartile ranges, and percentile ranks for the eight EPSI scales within cisgender sexual minority populations. Distinct patterns of eating-pathology symptoms were evidenced among the cisgender sexual minority groups. Cisgender bi + women exhibited the highest scores for Body Dissatisfaction, Binge Eating, and Restricting compared to other groups, whereas cisgender bi + men reported the highest scores for Excessive Exercise. Cisgender gay men had significantly higher scores for Muscle Building and Negative Attitudes Toward Obesity compared to other groups.

CONCLUSION

These findings offer valuable benchmarks for interpreting EPSI scores in the assessment and treatment of eating disorders among cisgender sexual minority individuals.

Effectiveness of unguided internet-based computer self-help platforms for eating disorders (with or without an associated app): A systematic review

BACKGROUND

Following the COVID-19 pandemic, internet-based computer self-help platforms for eating disorders (EDs) became increasingly prevalent as a tool to effectively prevent and treat ED symptoms and related behaviours. This systematic review explored the effectiveness of unguided internet-based computer self-help platforms for EDs.

METHODS

From inception to the 31st of May 2024, a systematic search of Ovid MEDLINE, Embase, Global Health, and APA PsycInfo was conducted. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Outcome quality assessments were conducted according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE).

RESULTS

12 RCTs, with a total of 3400 participants, were included. 2 studies explored the effectiveness as primary prevention, 7 as secondary prevention, and 3 as tertiary intervention. The gathered literature demonstrated unguided internet-based computer self-help platforms as effective in reducing ED core symptoms and related behaviours, with psychoeducation, cognitive behavioural, and dissonance-based approaches being the most prevalent approaches.

CONCLUSIONS

Unguided internet-based computer self-help platforms are effective in the short-term reduction of ED symptoms and associated behaviours and should be implemented in the early stages of a tiered healthcare system for ED treatments.

A call for strategy on eating disorders: the need for a comprehensive eating disorder strategy in England and specific guidance for the remote delivery of eating disorder services

There are growing calls for a comprehensive, evidence-based national eating disorder (ED) strategy for England. This is due to the rising prevalence of EDs, the lack of national guidance around different ED presentations (and potentially varying treatment needs), ad hoc data collection, and inconsistencies in both care and evaluation of service provision quality. Furthermore, the shift towards remote delivery of care during the COVID-19 pandemic underscores the need for government strategy to include specific guidance on remote delivery of ED services. The increased use of remote healthcare presents an opportunity to mitigate regional disparities in the provision of care. However, there are distinct challenges when delivering ED services remotely. In this position paper, we firstly highlight the growing need for a comprehensive national ED strategy to combat the rising prevalence and harm of EDs. Secondly, we specify the importance of ensuring that future governmental strategy incorporates evidence-based guidelines specific to remote delivery of ED services. This is crucial for promoting consistent provision of ED care. We set out the lack of comprehensive national data, and the need for further research into remote service delivery.

Eating disorders and psychiatric comorbidity among first-year university students in Sweden: Prevalence and risk factors

BACKGROUND

This study explored eating disorders (ED) prevalences, comorbidity of ED with other mental disorders, and risk factors for ED among university students. ED included binge eating disorder (BED), bulimia nervosa (BN), or other specified feeding and eating disorders (OSFED).

METHODS

A total of 3425 first-year university students in Sweden completed an online survey covering a range of criteria for psychiatric diagnoses, within the World Mental Health International College Student (WMH-ICS) initiative. Pearson's χ2 -tests were used to compare algorithm-based diagnostic prevalences for eating disorders and other comorbid psychiatric disorders between three groups: students with ED with or without other comorbid psychiatric disorders (A), students with psychiatric disorders but no ED comorbidity (B), and students with no psychiatric disorders (C). Multinomial logistic regression was used to calculate between-group comparisons of odds ratios for independent risk factors, where group B served as the reference group for comparisons with groups A and C.

RESULTS

Of the total sample, 75% had at least one psychiatric disorder and 28% had at least one lifetime ED diagnosis. Students with ED (group A) reported higher prevalences for comorbid anxiety disorders, depression, suicidal behavior, and non-suicidal self-injury compared to students with psychiatric disorders but no ED (group B). Group A participants exhibited a higher risk of hazardous drinking, were more likely to have received medical treatment, and to identify as bisexual. Compared to group B, students with no psychiatric disorders (group C) were more likely to report better mental and physical health, but less likely to engage in hazardous drinking, and to have sought mental health treatment.

CONCLUSIONS

A large proportion of students with ED had additional psychiatric disorders, indicating that individuals with ED suffer from multiple mental health problems. It is crucial that student health services acquire competency to offer effective ED assessment and treatment.

Exploring Biases of Large Language Models in the Field of Mental Health: Comparative Questionnaire Study of the Effect of Gender and Sexual Orientation in Anorexia Nervosa and Bulimia Nervosa Case Vignettes

Background

Large language models (LLMs) are increasingly used in mental health, showing promise in assessing disorders. However, concerns exist regarding their accuracy, reliability, and fairness. Societal biases and underrepresentation of certain populations may impact LLMs. Because LLMs are already used for clinical practice, including decision support, it is important to investigate potential biases to ensure a responsible use of LLMs. Anorexia nervosa (AN) and bulimia nervosa (BN) show a lifetime prevalence of 1%-2%, affecting more women than men. Among men, homosexual men face a higher risk of eating disorders (EDs) than heterosexual men. However, men are underrepresented in ED research, and studies on gender, sexual orientation, and their impact on AN and BN prevalence, symptoms, and treatment outcomes remain limited.

objectives

We aimed to estimate the presence and size of bias related to gender and sexual orientation produced by a common LLM as well as a smaller LLM specifically trained for mental health analyses, exemplified in the context of ED symptomatology and health-related quality of life (HRQoL) of patients with AN or BN.

Methods

We extracted 30 case vignettes (22 AN and 8 BN) from scientific papers. We adapted each vignette to create 4 versions, describing a female versus male patient living with their female versus male partner (2 × 2 design), yielding 120 vignettes. We then fed each vignette into ChatGPT-4 and to "MentaLLaMA" based on the Large Language Model Meta AI (LLaMA) architecture thrice with the instruction to evaluate them by providing responses to 2 psychometric instruments, the RAND-36 questionnaire assessing HRQoL and the eating disorder examination questionnaire. With the resulting LLM-generated scores, we calculated multilevel models with a random intercept for gender and sexual orientation (accounting for within-vignette variance), nested in vignettes (accounting for between-vignette variance).

Results

In ChatGPT-4, the multilevel model with 360 observations indicated a significant association with gender for the RAND-36 mental composite summary (conditional means: 12.8 for male and 15.1 for female cases; 95% CI of the effect -6.15 to -0.35; P=.04) but neither with sexual orientation (P=.71) nor with an interaction effect (P=.37). We found no indications for main effects of gender (conditional means: 5.65 for male and 5.61 for female cases; 95% CI -0.10 to 0.14; P=.88), sexual orientation (conditional means: 5.63 for heterosexual and 5.62 for homosexual cases; 95% CI -0.14 to 0.09; P=.67), or for an interaction effect (P=.61, 95% CI -0.11 to 0.19) for the eating disorder examination questionnaire overall score (conditional means 5.59-5.65 95% CIs 5.45 to 5.7). MentaLLaMA did not yield reliable results.

Conclusions

LLM-generated mental HRQoL estimates for AN and BN case vignettes may be biased by gender, with male cases scoring lower despite no real-world evidence supporting this pattern. This highlights the risk of bias in generative artificial intelligence in the field of mental health. Understanding and mitigating biases related to gender and other factors, such as ethnicity, and socioeconomic status are crucial for responsible use in diagnostics and treatment recommendations.

Sexual and gender minority youth in Canada: An investigation of disparities in positive mental health

OBJECTIVES

While studies indicate that 2SLGBTQ + youth are more likely to experience negative psychological outcomes compared to their heterosexual and cisgender peers, less is known about the positive mental health (PMH) of 2SLGBTQ + youth in Canada. To fill this gap, we investigated disparities in PMH by self-reported sexual attraction among 15‒17-year-olds and gender modality among 12‒17-year-olds.

METHODS

We analyzed data from youth respondents in the 2019 Canadian Health Survey on Children and Youth. We obtained estimates of average life satisfaction and high self-rated mental health, happiness, autonomy, competence, and relatedness for youth with an exclusively heterosexual attraction and youth with a minority sexual attraction (those exclusively attracted to the same gender, and those attracted to both females and males), and for cisgender and gender minority youth. Regression analyses were conducted to test for disparities on each PMH outcome.

RESULTS

Compared with exclusively heterosexual youth, sexual minority youth reported lower life satisfaction and were less likely to report high self-rated mental health, happiness, autonomy, competence, and relatedness. Significant disparities were more consistently found for youth attracted to both females and males than youth exclusively attracted to the same gender. Gender minority (versus cisgender) youth also reported lower average life satisfaction and were less likely to report high self-rated mental health, happiness, autonomy, competence, and relatedness.

CONCLUSION

Although this study provides evidence for the presence of disparities in PMH, its strength-based focus on PMH also documents the presence of well-being among many sexual and gender minority youth in Canada.

Sexual orientation discrimination and eating disorder symptoms in early adolescence: a prospective cohort study

BACKGROUND

Sexual orientation discrimination increases the risks of negative health outcomes for sexual minorities. Previous studies have found increased rates of eating disorder symptoms in sexual minority individuals, which is attributable to minority stress and discrimination that they experience. Emerging research suggests relationships between sexual orientation discrimination and eating disorder symptoms. However, there is a lack of studies focusing on early adolescents. The objective of this study was to determine prospective associations between discrimination based on sexual orientation and eating disorder symptoms in a national sample of 10-13-year-old early adolescents in the U.S.

METHODS

We examined prospective data from Year 2 (2018-2020) and Year 3 (2019-2021) of the Adolescent Brain Cognitive Development (ABCD) Study (N = 8976). Multiple logistic regression analyses were used to estimate associations between self-reported experiences of sexual orientation discrimination in Year 2 and eating disorder symptoms in Year 3, adjusting for potential confounders, including eating disorder symptoms in Year 2. Sexual orientation discrimination was assessed based on the Perceived Discrimination Scale, which measures adolescents' perception of being treated unfairly based on various sociodemographic characteristics. Eating disorder symptoms were based on the parent-reported Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5).

RESULTS

In this demographically diverse sample of early adolescents (N = 8976, age range 10-13 years at Year 2), 5.5% of adolescents reported sexual orientation discrimination in Year 2. The prevalence of parent-reported eating disorder symptoms in Year 3 varied from 1.0 to 8.3%. In the adjusted models, sexual orientation discrimination was prospectively associated with worry about weight gain (adjusted odds ratio [aOR] 2.33, 95% confidence interval [CI] 1.15-4.69) and self-worth tied to weight (aOR 1.60, 95% CI 1.01-2.53) one year later.

CONCLUSIONS

Early adolescents who have experienced sexual orientation discrimination have higher odds of experiencing eating disorder symptoms, particularly worrying about weight gain and tying self-worth to weight. Clinicians may consider screening for sexual orientation discrimination and providing affirmative, trauma-informed care when evaluating and treating even younger sexual minority adolescents for eating disorder symptoms.

Eating disorders: etiology, risk factors, and suggestions for prevention

PURPOSE OF REVIEW

The incidence of eating disorders has increased worldwide. This narrative review gives an overview of research on etiology and risk factors of eating disorders published in 2022-2024.

RECENT FINDINGS

Eating disorders arise from a complex set of risk factors. The recent increase in incidence of eating disorders can be linked to root causes that include sociocultural pressure to conform to unrealistic and gendered body ideals, rise in obesogenic environments, and the global COVID-19 pandemic. Recent studies have shown that screen time and social media intensify sociocultural pressure to look a certain way. Individual-specific risk factors also increase the likelihood of onset of eating disorders. These include sports, stressful and traumatic life events, family factors, and psychological factors, including disgust sensitivity, aversive experiences, low self-esteem, perfectionism, neuroticism, obsessive-compulsive and impulsive features, and emotional dysregulation. Preexisting mental health conditions, particularly anxiety, depression, and posttraumatic stress disorder, and neurodevelopmental conditions, such as autism and attention-deficit hyperactive disorder, are also associated with increased eating disorder risk. Genetic and biological factors contribute both to risk and resiliency.

SUMMARY

The risk factors of eating disorders are well established. Future studies should focus on increasing resilience and preventive interventions.

Measurement invariance of the Intuitive Eating Scale-2 across country, ethnicity, sex, and sexual orientation: A cross-cultural study between Brazil and the U.S

Intuitive eating is defined as being connected to internal hunger, satiety, and appetitive cues and flexibly using these cues to determine when, what, and how much to eat. The Intuitive Eating Scale-2 (IES-2) is a widely used measure of facets of intuitive eating. However, the scale has shown unstable factor structure in several validation studies and there is a lack of studies investigating the measurement invariance of the IES-2 beyond sex. We aimed to evaluate the psychometric properties of the IES-2, testing several factor structures among Brazilian and U.S. samples of men and women; to test measurement invariance across country of origin, ethnicity, sex, and sexual orientation; and to evaluate its internal consistency. Three models of the latent structure of the IES-2 were tested using confirmatory factor analyses (CFA) in a total of 1072 young adults (452 Brazilians and 620 Americans), aged 18-35 years. Results demonstrated that only a 3-factor solution with 11 items of the IES-2 showed adequate fit to the data for both countries. This model demonstrated scalar invariance across sex and sexual orientation, but only configural invariance was found across country of origin and ethnicity. Good internal consistencies were found for both the Brazilian and American samples. The present study provides support for a 3-factor solution with 11 items of the IES-2, to Brazilian and American samples. The study also offers evidence of internal consistency, and invariance between sex (i.e., male and female) and sexual orientation (i.e., heterosexual participants and sexual minority participants).

Eating Disorders in Sexual and Gender Minority Adolescents

PURPOSE OF REVIEW

To consolidate recent literature addressing eating disorders and disordered eating behaviors among sexual and gender minority (SGM) adolescents, including but not limited to lesbian, gay, bisexual, transgender, and queer (LGBTQ) adolescents.

RECENT FINDINGS

Sexual and gender minority adolescents are at heightened vulnerability to eating disorders and disordered eating behaviors compared to their cisgender and heterosexual peers, potentially due to minority stress, gender norms, objectification, and the influence of the media, peers, and parents. We report findings from recent literature on the epidemiology and prevalence, assessment, mental health comorbidity, quality of life and psychosocial functioning, risk and protective factors, and treatment and interventions for eating disorders in sexual and gender minority adolescents. Addressing eating disorders in sexual and gender minority adolescents requires an integrated approach consisting of screening, tailored treatment, and comprehensive support to address intersectional challenges. Gender-affirming and trauma-informed care approaches may be considered.

Factors increasing the risk for food addiction in Ecuadorian students

Background

Food addiction (FA) is a construct that has gained interest in recent years, but its relevance in the Ecuadorian population has not yet been explored. The aims of this study were to explore the differences in the psychological profile (including FA) between university students from Ecuador and to identify the underlying structure of the relationships of the FA severity level through a mediational model.

Methods

The sample consisted of 972 university students, women and men (mean age: 20.1 years old, SD = 2.6), recruited from four Ecuadorian regions. The assessment tools included a unidimensional scale of FA, eating-related measures, emotion regulation state, impulsivity, and psychopathology state. Path analysis modeled the direct and indirect effects explaining the FA severity level.

Results

The results indicated that higher psychopathological levels were associated with FA. Similarly, no differences in FA were observed between the Ecuadorian regions. The path analysis suggested that older age, female sex, and higher difficulties in emotional regulation, impulsivity, negative mood, and anxiety trigger disordered eating; subsequently, more impaired eating behavior impacted the FA level.

Conclusion

FA is a complex clinical entity that includes multiple components related to eating disorders (EDs) and other mental health problems. The results of this study provide empirical knowledge for designing evidence-based prevention and treatment strategies.

Effects of Bullying on Anxiety, Depression, and Posttraumatic Stress Disorder Among Sexual Minority Youths: Network Analysis

BACKGROUND

Bullying victimization is highly prevalent among sexual minority youths, particularly in educational settings, negatively affecting their mental health. However, previous studies have scarcely explored the symptomatic relationships among anxiety, depression, and posttraumatic stress disorder (PTSD) among sexual minority youths who experienced bullying on college campuses.

OBJECTIVE

The objectives of our study were to (1) characterize the anxiety-depression-PTSD network structures of gay or lesbian, bisexuals, and other sexual minority youths previously bullied on college campuses; and (2) compare symptomatic associations in the anxiety-depression-PTSD networks among bullied sexual minority youths and heterosexual youths' groups.

METHODS

This cross-sectional study recruited college participants from Jilin Province, China. Data were analyzed using a subset of the data extracted after screening for sexual orientation and history of bullying victimization. Sexual minority youths were then divided into 3 subgroups: gay or lesbian (homosexual), bisexual, and other. Mental health symptom severity was assessed using scales: the 7-item Generalized Anxiety Disorder Scale measuring anxiety, the 9-item Patient Health Questionnaire measuring depression, and the 10-item Trauma Screening Questionnaire measuring PTSD symptoms. Combining the undirected and Bayesian network analyses, the anxiety-depression-PTSD networks were compared among sexual minority youths subgroups, and the difference between heterosexual youths and sexual minority youths was investigated. Chi-square tests were used to compare the difference in categorical variables, while independent-sample t tests were run on continuous variables.

RESULTS

In this large-scale sample of 89,342 participants, 12,249 identified as sexual minority youths, of which 1603 (13.1%, 95% CI 12.5%-13.7%) reported being bullied on college campuses in the past year. According to the expected influence (EI) and bridge expected influence (bEI) index, in the global network structure of anxiety, depression, and PTSD, sad mood (EI=1.078, bEI=0.635) and irritability (EI=1.077, bEI=0.954) were identified as central and bridge symptoms; emotional cue reactivity (EI=1.015) was a central symptom of PTSD in this global network. In the anxiety-depression-PTSD Bayesian network, anhedonia had the highest prediction priority for activating other symptoms; and feeling afraid linked symptoms from anxiety to the PTSD community. Compared to their heterosexual counterparts, sexual minority youths exhibited a stronger association between difficulty concentrating and appetite. The "sad mood-appetite" edge was strongest in the gay or lesbian network; the "irritability-exaggerated startle response" edge was strongest in the bisexual network.

CONCLUSIONS

For the first time, this study identified the most central and bridge symptoms (sad mood and irritability) within the depression-anxiety-PTSD network of sexual minority youths with past bullying-victim experiences on college campuses. Emotional cue reactivity, anhedonia, and feeling afraid were other vital symptoms in the comorbid network. Symptomatic relationships existed showing heterogeneity in bullied heterosexual youths and sexual minority youth networks, which also was present within the sexual minority youth subgroups. Consequently, refined targeted interventions are required to relieve anxiety, depression, and PTSD symptoms.

The social epidemiology of binge-eating disorder and behaviors in early adolescents

BACKGROUND

Binge-eating disorder (BED) is the most common eating disorder phenotype and is linked to several negative health outcomes. Yet, little is known about the social epidemiology of BED, particularly in early adolescence. The objective of this study was to examine the associations between sociodemographic characteristics and BED and binge-eating behaviors in a large, national cohort of 10-14-year-old adolescents in the United States (U.S.) METHODS: We conducted a cross-sectional analysis of two-year follow-up data from the Adolescent Brain Cognitive Development (ABCD) Study (2018 - 2020) that included 10,197 early adolescents (10 - 14 years, mean 12 years) in the U.S. Multivariable logistic regression models were used to assess the associations between sociodemographic characteristics and BED and binge-eating behaviors, defined based on the Kiddie Schedule for Affective Disorders and Schizophrenia.

RESULTS

In this early adolescent sample (48.8% female, 54.0% White, 19.8% Latino/Hispanic, 16.1% Black, 5.4% Asian, 3.2% Native American, 1.5% Other), the prevalence of BED and binge-eating behaviors were 1.0% and 6.3%, respectively. Identifying as gay or bisexual (compared to heterosexual; adjusted odds ratio [AOR]: 2.25, 95% CI 1.01-5.01) and having a household income of less than $75,000 (AOR: 2.05, 95% CI: 1.21-3.46) were associated with greater odds of BED. Being male (AOR: 1.28, 95% CI: 1.06-1.55), of Native American (AOR: 1.60, 95% CI: 1.01-2.55) descent, having a household income less than $75,000 (AOR: 1.34, 95% CI: 1.08-1.65), or identifying as gay or bisexual (AOR for 'Yes' Response: 1.95, 95% CI: 1.31-2.91 and AOR for 'Maybe' Response: 1.81, 95% CI: 1.19-2.76) were all associated with higher odds of binge-eating behaviors.

CONCLUSION

Several sociodemographic variables showed significant associations with binge-eating behaviors, which can inform targeted screening, prevention, and education campaigns for BED among early adolescents.

Thyroid dysfunction in children and adolescents affected by undernourished and overnourished eating disorders

Eating disorders (ED) are one of the most prevalent chronic disorders in adolescents and young adults, with a significantly increasing prevalence in younger children, particularly in girls. Even if obesity in essence is not framed as an eating disorder and has always been considered a separate pathology, ED and obesity could be considered part of a continuum. It has become evident that one condition can lead to another, such as binge eating disorder (BED) and bulimia nervosa, and that they share the same repercussions in terms of psychosocial, metabolic, and nutritional health. This narrative review aims to investigate the hypothalamic-pituitary-thyroid axis in undernourished and overnourished patients with ED, including obesity, in order to highlight the relationship between weight control and thyroid function and its effects and to consider therapeutic and preventive strategies in children and adolescents. Literature data report that thyroid alterations occur in patients with ED, both underweight and overweight, and represent a continuum of changes depending on the severity and time course of the disease involving the endocrine system. Considering the relevant role thyroid hormones (TH) play not only in energy expenditure (EE) but also in metabolic control and cardiovascular risks related to dysmetabolism and mood regulation, continuous monitoring of thyroid homeostasis in patients with ED is mandatory to prevent severe complications and to start early treatment when necessary.

Factors associated with lifetime history of eating disorder in non-psychotic patients with suicidal ideation

BACKGROUND

Data on the sociodemographic, biographical, and clinical factors associated with a lifetime diagnosis of eating disorders (ED) in patients with non-psychotic mental disorders (NPMD) and suicidal ideation (SI) are scarce.

METHODS

A cohort study was conducted at the Moscow Research and Clinical Center for Neuropsychiatry. The sample consisted of consecutive patients with non-psychotic mental disorders and SI, aged 1845 years. Participants with a lifetime diagnosis of anorexia and/or bulimia (then in remission or recovery) were compared with those without ED in terms of their sociodemographic profile, clinical characteristics, lifetime traumatic events, and some behavioral patterns. All participants underwent the Russian version of the Self-Injurious Thoughts and Behaviors Interview and completed the Brief Reasons for Living Inventory, the State and Trait Anxiety Inventory, and the Beck Depression Inventory.

RESULTS

A total of 892 patients with non-psychotic mental disorders and SI were included in the study. The mean age was 25.7 years, and 84% were assigned female at birth. Same-sex experience was more common in the ED group. Patients with an ED were more likely to have a history of physical and sexual abuse and to have witnessed domestic violence. The proportion of participants with piercings, tattoos, or severe body modifications was significantly higher in the ED group. Patients with a lifetime ED were more likely to engage in nonsuicidal self-injurious behaviors and to have a history of suicide attempts.

CONCLUSION

Lifetime ED in NPMD patients with SI is associated with younger age, being assigned female at birth, having an alternative gender identity, having same-sex experience, having more than one psychiatric diagnosis, having been diagnosed with bipolar disorder, experiencing severe depression and anxiety, being exposed to multiple traumatic experiences, having various body modifications, practicing NSSI, and having a lifetime story of suicide attempts.

Sexual Satisfaction among Lesbian and Heterosexual Cisgender Women: A Systematic Review and Meta-Analysis

BACKGROUND

Sexual satisfaction is a complex, multifaceted, and broad concept that is influenced by several factors. The minority stress theory posits that sexual and gender minorities are at a particular risk for stress due to stigma and discrimination at the structural, interpersonal, and individual levels. The aim of this systematic review and meta-analysis was to evaluate and compare the sexual satisfaction between lesbian (LW) and heterosexual (HSW) cisgender women.

METHODS

A systematic review and meta-analysis were conducted. We searched the PubMed, Scopus, Science Direct, Websci, Proquest, and Wiley online databases from 1 January 2013 to 10 March 2023 to identify the published observational studies on sexual satisfaction in women according to their sexual orientation. The risk of bias in the selected studies was assessed using the JBI critical appraisal checklist for the analytical cross-sectional studies.

RESULTS

A total of 11 studies and 44,939 women were included. LW reported having orgasms during a sexual relationship more frequently than HSW, OR = 1.98 (95% CI 1.73, 2.27). In the same direction, the frequency of women reporting "no or rarely" for having orgasms during their sexual relationships was significantly lower in the LW than the HSW, OR = 0.55 (95% CI 0.45, 0.66). The percentage of the LW who reported having sexual intercourse at least once a week was significantly lower than that of the HSW, OR = 0.57 for LW (95% CI 0.49, 0.67).

CONCLUSIONS

Our review showed that cisgender lesbian women reached orgasm during sexual relations more often than cisgender heterosexual women. These findings have implications for gender and sexual minority health and healthcare optimization.
