Background/Objectives: Persons identifying as lesbian, gay, bisexual, pansexual, omnisexual, queer, questioning, fluid, asexual, or other non-heterosexual orientations (LGB+ persons) have been identified as a risk group for sexual victimization (SV), which can have long-lasting negative effects on well-being and physical, mental, sexual, and reproductive health. Othering-Based Stress (OBS)—reflecting societal processes of othering and resulting from stigma, prejudice, and discrimination—may contribute to increased vulnerability to SV and its consequences in LGB+ persons and affect help-seeking behavior following victimization. This study examines the impact of SV on LGB+ persons and their help-seeking behavior after victimization. Methods: Using a mixed-methods explanatory sequential design, first survey data from a nationally representative sample of the Belgian population on SV, its consequences, and subsequent help-seeking behavior were collected from 4632 individuals. Of these, 2965 participants (2601 heterosexual and 364 LGB+ individuals) experienced SV and represented the final sample for the quantitative analyses. In a second phase, in-depth interviews were conducted with 40 LGB+ victims to explore their experiences more thoroughly. Results: LGB+ individuals reported more negative consequences following SV than heterosexual persons, particularly regarding identity-related processes such as questioning gender expression and decreases in self-esteem. They also reported additional barriers to disclosing SV and seeking help from professional services or the police, including fears of stigma, invalidation, and concerns about professionals’ LGB+ competence. No significant differences were found between LGB+ persons who explicitly identified as belonging to a sexual minority group and those who did not, neither in the perceived consequences of SV nor in help-seeking barriers. Conclusions: LGB+ victims of sexual violence experienced more severe identity-related consequences and faced greater barriers to professional support than heterosexual victims. These results highlight the urgent need for trauma-informed, LGB+-inclusive services and structural policy measures to improve access to appropriate care. Full article

Objectives: Evaluate the genetic diversity and productive traits of crossbred cattle in the Caribbean region of Colombia, through analyses derived from the assessment of the genome-wide single-nucleotide polymorphism (SNP). Methods: A total of 590 individuals and 66,098 SNPs were analyzed by principal components analysis (PCA) and detection of runs of homozygosity (ROH). The population was composed of 531 heifers marked as crossbreed and a group of 59 heifers marked as purebred Gyr. Additionally, allele frequencies were calculated for commercially important traits (CSN2, CSN3, LGB, DGAT1, GH1, CAPN1_316, CAPN1_350, CAPN1_4751, CAST_282, CAST_2870, and CAST_2959). Results: Global differences in PCA were 7.35%, and principal components explained 1.94% and 5.41% of the variation. Five ROH islands were identified in crossbred animals on chromosomes 2, 5, 7, 8, and 12. The majority of observed ROH classes were shorter than 2 Mb, 54% in crossbreed cattle and 47% in Gyr cattle. Individual inbreeding was 5.2% in crossbreed and 12% in Gyr cattle. Both groups had similar allelic and genotypic frequencies for most of the evaluated commercial traits. Only a wide variation was observed in the genes related to growth hormone (GH1) and Calpastatin (CAST_2870 and CAST_22959). Crossbreed heifers had desired allele frequencies for better milk production and quality in the genes CSN2, LGB, DGAT1, and GH1, as well as in the genes CAST_2870 and CAST_2959. Conclusions: Crossbreed cattle in the Colombian Caribbean region possess high genetic diversity and desirable allele frequencies to implement breeding and intense selection programs aimed at improving production yields.

Coming out has been found to be associated with favorable long-term social and psychological outcomes among lesbian, gay, and bisexual (LGB) people. It is therefore important to understand the system of social and psychological factors that predict degree of outness in this population. The integrative theoretical model proposed in this article postulates that social factors (e.g., exposure to minority stressors, access to social support) trigger changes in sexual identity, which in turn determine one’s degree of outness. The model is tested in two cross-sectional survey studies (Study 1 [N = 295]) and Study 2 [N = 156]) of LGB people in the United Kingdom. Discrimination and general social support were directly and positively associated with outness and indirectly through the mediation of sexual identity processes. LGB social support was indirectly associated with outness through sexual identity processes. Interventions should focus on facilitating access to varied social support and on preventing or alleviating sexual identity threat in the face of minority stressors. Full article

(1) Background: This paper presents an analysis of the associations between minority stressors and activism in the population of lesbian, gay, and bisexual individuals in Poland. (2) Methods: The cross-sectional online-based research was conducted among 192 lesbian, gay, and bisexual (LGB) people in two groups: activists (n = 51) and people not engaged in activism (n = 141). Four scales of the Sexual Minority Stress Scale were used: Internalized Homophobia, Expectation of Rejection, Concealment, and Sexual Minority Negative Events Scale. Activism was measured using the Activism Scale and a single item asking about belonging to an activist group. (3) Results: Activists, lesbians, and gays scored significantly higher in the Sexual Minority Negative Events than people not involved in activism and bisexual individuals. Attitude toward LGBT+ activism correlated weakly and positively with Sexual Minority Negative Events and Expectation of Rejection while negatively with Internalized Homophobia. The Network Analysis showed that positive attitudes toward LGBT+ activism, the expectation of rejection, and negative events in minority stress are the most influential variables in the network model, playing a crucial role in the interaction between particular dimensions of minority stress. (4) Conclusions: Prevention and intervention programs should focus on reducing minority stress, especially negative events and rejection, especially among lesbians, gays, and people engaged in LGBT+ activism. The cooperation of politicians, lawyers, social workers, and psychologists is required to decrease homophobia and the stigmatization of people representing sexual and gender minorities. Full article

Although several studies have found disparities in health outcomes between heterosexual and lesbian, gay, and bisexual (LGB)-identifying individuals, few studies have focused on subjective well-being and protective factors for health and well-being. The purpose of this work is twofold: (1) to examine the relevance of sexual orientation to health and well-being in women and men; (2) to identify protective and risk factors for psychological distress, self-rated health, and well-being for gay men, lesbian women, bisexual women and men, and heterosexual women and men. The sample consisted of 908 women and 586 men from the general Spanish population aged 16–64, half of whom identified themselves as LGB and half as heterosexual. All were assessed using eight questionnaires and inventories. The results showed that differences varied depending on the health indicator considered. In general, bisexuals had the poorest health, with lower self-rated health and lower self-esteem. In all groups, self-esteem was a protective factor against psychological distress and was associated with better health and well-being. To a lesser extent, social support served as a protective factor against psychological distress and was associated with greater well-being in all groups. It is concluded that although sexual orientation is relevant to the health and well-being of individuals, there are differences among sexual minorities, with bisexuals having lower self-esteem than homosexuals.

Since the WHO’s 2021 aging redefinition emphasizes “healthy aging” by focusing on the elderly’s ability to perform daily activities, sarcopenia, which is defined as the loss of skeletal muscle mass, is now becoming a critical health concern, especially in South Korea with a rapidly aging population. Therefore, we develop a prediction model for sarcopenia by using machine learning (ML) techniques based on the Korea National Health and Nutrition Examination Survey (KNHANES) data 2008–2011, in which we focus on the role of socioeconomic status (SES), social infrastructure, and quality of life (QoL) in the prevalence of sarcopenia. We successfully identify sarcopenia with approximately 80% accuracy by using random forest (RF) and LightGBM (LGB), CatBoost (CAT), and a deep neural network (DNN). For prediction reliability, we achieve area under curve (AUC) values of 0.831, 0.868, and 0.773 for both genders, males, and females, respectively. Especially when using only male data, all the models consistently exhibit better performance overall. Furthermore, using the SHapley Additive exPlanations (SHAP) analysis, we find several common key features, which mainly contribute to model building. These include SES features, such as monthly household income, housing type, marriage status, and social infrastructure accessibility. Furthermore, the causal relationships of household income, per capita neighborhood sports facility area, and life satisfaction are analyzed to establish an effective prediction model for sarcopenia management in an aging population.

Introduction: Sexual pleasure is a human right and a central aspect of human sexuality that contributes significantly to people’s overall well-being, making it an essential element to consider in clinical settings. This study aims to expand the understanding of sexual pleasure by examining how LGB+ people (lesbian, gay, bisexual, and other minority sexual orientations)-who perceived having a sexual problem-define solitary and partnered sexual pleasure. Methods: A cross-sectional exploratory qualitative study was conducted online. The current study included 85 people who self-identified as LGB+ and reported experiencing a sexual problem. Data analysis was performed using summative content analysis. Results: The results for solitary sexual pleasure comprised the creation of 5 categories (Enhancing the relationship with oneself, Specification of solitary pleasure, Negative experience, Unrestrained experience and A goal). For partnered sexual pleasure, 9 categories were created (The perks of being with another, Openness to experience, A result of sexual techniques, Psychophysiological experience, Misconceptions about sexual pleasure, Absence of intrapersonal constraints, Undesirable feelings, Explicit consent, and Absence of interpersonal constraints). Discussion: Despite reporting sexual problems, most participants reported having experienced sexual pleasure, and were able to define it. This study provided a deeper understanding of the perspectives on and experiences of sexuality among LGB+ people who experience sexual problems. Our findings highlight that current diagnostic criteria (e.g., DSM-5) do not seem to align with the problems reported by this sample population (the problems presented are beyond their sexual function). This reinforces the importance of viewing sexual problems from a perspective that goes beyond the categorial psychopathology model. Our study’s findings may offer valuable insights for the evaluation and treatment of sexual problems, where sexual pleasure is considered a crucial aspect of sexual well-being. Full article

Studies have shown separately that sexual minority populations generally experience poorer chronic health outcomes compared with those who identify as heterosexual, as do rural populations compared with urban dwellers. This Canadian national observational study explored healthcare patterns at the little-understood intersections of lesbian, gay, or bisexual (LGB) identity with residence in rural and remote communities, beyond chronic disease status. The secondary analysis applied logistic regressions on multiple linked datasets from representative health surveys, administrative hospital records, and a geocoded index of community remoteness to examine differences in the risk of potentially avoidable cardiometabolic-related hospitalization among adults of working age. Among those with an underlying cardiometabolic condition and residing in more rural and remote communities, a significantly higher hospitalization risk was found for LGB-identified persons compared with their heterosexual peers (odds ratio: 4.2; 95% confidence interval: 1.5–11.7), adjusting for sociodemographic characteristics, behavioral risk factors, and primary healthcare access. In models stratified by sex, the association remained significant among gay and bisexual men (5.6; CI: 1.3–24.4) but not among lesbian and bisexual women (3.5; CI: 0.9–13.6). More research is needed leveraging linkable datasets to better understand the complex and multiplicative influences of sexual minority status and rurality on cardiometabolic health to inform equity-enhancing preventive healthcare interventions.

Understanding cardiometabolic health among lesbian, gay, and bisexual (LGB) people is challenged by methodological constraints, as most studies are either based on nonprobability samples or assume that missing values in population-based samples occur at random. Linking multiple years of nationally representative surveys, hospital records, and geocoded data, we analyzed selection biases and health disparities by self-identified sexual orientation in Canada. The results from 202,560 survey respondents of working age identified 2.6% as LGB, 96.4% as heterosexual, and <1.0% with nonresponse to the sexual identity question. Those who did not disclose their sexual identity were older, less highly educated, less often working for pay, and less often residing in rural and remote communities; they also had a diagnosed cardiometabolic condition or experienced a cardiometabolic-related hospitalization more often. Among those reporting their sexual identity, LGB individuals were younger, more likely to smoke tobacco or drink alcohol regularly, more likely to have heart disease, and less likely to have a regular medical provider than heterosexual persons. This investigation highlighted the potential of leveraging linked population datasets to advance measurements of sexual minority health disparities. Our findings indicated that population health survey questions on sexual identity are not generally problematic, but cautioned that those who prefer not to state their sexual identity should neither be routinely omitted from analysis nor assumed to have been randomly distributed.

Background: A rising number of monkeypox cases have been detected in Europe and several Western nations. Evaluating the fear associated with monkeypox is crucial to determine the necessity for tailored education and prevention programs for specific populations. This study explores the psychological and social factors linked to the fear response to monkeypox. Methods: Nine self-report measures were completed by 333 participants (212 women, 110 men, and 11 individuals identifying as other genders) from the general Italian population, investigating different psychosocial variables. Results: The findings revealed that higher levels of monkeypox fear were linked to identifying as LGB+ or having close associations with the LGBTQI+ community, being single, having lower education levels, placing greater importance on religion, receiving more COVID-19 vaccine doses, having a lower current quality of life, and attributing increased impairment to the COVID-19 pandemic. Psychologically, higher levels of monkeypox fear were associated with higher levels of epistemic credulity, close-mindedness, anxiety, difficulty expressing emotions, and difficulty processing them. Conversely, lower levels of monkeypox fear were related to the belief that the media exaggerated the risks associated with monkeypox epidemics. A partial mediation model was presented and tested. Conclusions: Collecting and utilizing this data can help design targeted education and prevention programs to overcome the fear of monkeypox and promote healthier behaviors. Full article

There is limited evolving literature on COVID-19 vaccine uptake and its barriers among sexual minority populations (lesbian, gay, bisexual, transgender, and queer [LGBTQ]), despite their increased COVID-19 risk factors. We assessed the differences in intention to receive the COVID-19 vaccine by self-reported likelihood of contracting COVID-19, anxiety/depression, discrimination frequency, social distancing stress, and sociodemographic factors across sexual orientation. An online national cross-sectional survey was conducted in the United States between 13 May 2021, and 9 January 2022, among adults aged ≥18 (n = 5404). Sexual minority individuals had a lower intention of receiving the COVID-19 vaccine (65.62%) than heterosexual individuals (67.56%). Disaggregation by sexual orientation, however, showed that gay participants had a higher intention of COVID-19 vaccination (80.41%) and lesbian (62.63%), bisexual (64.08%), and non-heterosexual, non-LGB sexual minority (56.34%) respondents had lower intentions of receiving the COVID-19 vaccine than heterosexual respondents. Sexual orientation significantly moderated the association between the perceived likelihood of receiving the COVID-19 vaccine and the self-reported likelihood of contracting COVID-19, anxiety/depression symptoms, and discrimination. Our findings further underline the importance of improving vaccination efforts and access among sexual minority individuals and other vulnerable groups. Full article

The role of ageism (i.e., discrimination against individuals or groups on the basis of their age), in particular toward the sexuality of the elderly, remains, to date, an overlooked issue. A few studies have suggested that ageistic stereotypes can negatively affect older adults’ sexual health. No data are available, in particular, about differences among heterosexual and LGB (lesbian, gay, and bisexual) populations. The present study aimed to investigate differences in perceived ageism and related dysfunctional beliefs in a sample of heterosexual (n = 104) and LGB (n = 103) older adults (aged 55 or older; mean age 66.5) and their impact on sexual health and satisfaction. LGB individuals reported higher rates of masturbation and sexual intercourse and an increased quality of sexual activity as compared to heterosexuals. In addition, no differences between the groups emerged as regards perceived ageism and dysfunctional beliefs toward ageing. In conclusion, LGB individuals perceived more ageism toward sexuality than their counterparts; however, heterosexuals were more likely to have dysfunctional beliefs toward sexuality in ageing. The study findings highlight the significance of examining sexual orientation to understand experiences of sexuality in ageing of the growing older population. Renewed socio-educational efforts based on these data are clearly needed. Full article

Diabetes is one of the most rapidly spreading diseases in the world, resulting in an array of significant complications, including cardiovascular disease, kidney failure, diabetic retinopathy, and neuropathy, among others, which contribute to an increase in morbidity and mortality rate. If diabetes is diagnosed at an early stage, its severity and underlying risk factors can be significantly reduced. However, there is a shortage of labeled data and the occurrence of outliers or data missingness in clinical datasets that are reliable and effective for diabetes prediction, making it a challenging endeavor. Therefore, we introduce a newly labeled diabetes dataset from a South Asian nation (Bangladesh). In addition, we suggest an automated classification pipeline that includes a weighted ensemble of machine learning (ML) classifiers: Naive Bayes (NB), Random Forest (RF), Decision Tree (DT), XGBoost (XGB), and LightGBM (LGB). Grid search hyperparameter optimization is employed to tune the critical hyperparameters of these ML models. Furthermore, missing value imputation, feature selection, and K-fold cross-validation are included in the framework design. A statistical analysis of variance (ANOVA) test reveals that the performance of diabetes prediction significantly improves when the proposed weighted ensemble (DT + RF + XGB + LGB) is executed with the introduced preprocessing, with the highest accuracy of $0.735$ and an area under the ROC curve (AUC) of $0.832$. In conjunction with the suggested ensemble model, our statistical imputation and RF-based feature selection techniques produced the best results for early diabetes prediction. Moreover, the presented new dataset will contribute to developing and implementing robust ML models for diabetes prediction utilizing population-level data. Full article

Background: Some (minority) groups (MGs) are more vulnerable to sexual violence (SV) exposure than others. Othering-based stress (OBS) may mediate the relationship between minority identification and SV. This study aims to assess the prevalence of SV in different MGs to explore the relationship between minority identification and SV, to investigate whether belonging to multiple MGs moderates this relationship, and to explore OBS SV moderation for different MGs. Method: Through an online survey administered to a nationally representative sample in Belgium, data was collected from 4632 persons, of whom 21.01% self-identified as belonging to a MG (SI-Minority). SV prevalence was measured using behaviorally specific questions based on the WHO definition of SV. SI-Minority participants received an additional scale on OBS. Results: SI-Minority participants reported more SV victimization compared to the non-minorities. However, this increased risk was not moderated by minority identification but linked to the socio-demographic SV risk markers common to minority individuals. Multiple-minority participants were found more at risk of SV compared to single-minority respondents. Lesbian, gay, bisexual, pan-/omnisexual, asexual, and other non-heterosexual (LGB+) participants were found more at risk than heterosexual participants. OBS was found to be significantly correlated to SV in sexual and gender minorities and in cultural minorities. Conclusions: This study contributes to our understanding of the relationship between minority identification, OBS, and SV. Studying both specific and common SV vulnerabilities and outcomes within specific societal subgroups and the general population may inform policy makers when allocating resources to those interventions with the largest societal impact.

Internalized sexual stigma (ISS) is one of the major issues that can compromise the health of sexual minority populations. This quantitative study aimed to examine: (1) the relationships of individual factors (gender, age, education level, sexual orientation, and age of identification of sexual orientation) and perceived family support with ISS; and (2) the associations of ISS with mood problems and the moderating effects of gender on the associations among Taiwanese young adult lesbian, gay, and bisexual (LGB) individuals. In total, 500 male and 500 female young adult LGB individuals aged between 20 and 30 years participated in this study. The experience of ISS, individual (e.g., gender, age, education level, sexual orientation, and age of identification of sexual orientation) and environmental factors (perceived family), mood problems (e.g., anxiety and depression) were collected. The individual and environmental factors related to ISS and the associations of ISS with mood problems were examined using multivariate linear regression analysis. The results indicated that gender, sexual orientation, age of identification of sexual orientation, and perceived family support were significantly associated with all or some dimensions of ISS in LGB individuals. Various dimensions of ISS had different relationships with anxiety and depression. Gender had moderating effects on the association between the identity dimension of ISS and sexual orientation as well as between the social discomfort dimension of ISS and anxiety. Various dimensions of ISS among LGB individuals should be routinely assessed by mental health service units. Intervention programs should be provided for LGB individuals, especially those with factors related to ISS. Full article
