In order to investigate the association between early life conditions and reproductive and sexuality-related life history outcomes among men, we conducted a meta-analysis that compiled the results of 198 articles. A total of 331 effect sizes drawn from 573 samples were included. The meta-analysis revealed that low family socioeconomic status was as...

This study tested the association between multiple prenatal and postnatal early life factors and adolescent sexual orientation in a longitudinal birth cohort. Factors included birth weight, gestational age, parental age at birth, number of older brothers and sisters, breastfeeding, maternal anxiety/depression, family socioeconomic position, parent–...

This study tested whether associations between childhood maltreatment and adolescent sexual orientation were accounted for by childhood gender nonconforming behavior (GNCB) in a prospective birth cohort (N = 5,007). Childhood parental maltreatment (physical and emotional) and GNCB were assessed on multiple occasions up to age 6 years, and sexual or...

This study quantified changes in self-reported sexual orientation from adolescence to early adulthood, and whether childhood gender nonconformity (GNC) predicted sexual orientation changes. Youth (2,678 boys and 3,359 girls; 96.09% ethnically White) from the Avon Longitudinal Study of Parents and Children (ALSPAC) were included. Self-reported sexua...

Background Lesbian, gay, bisexual, and asexual adolescents are at increased risk of poor mental health outcomes but it remains unknown whether this disparity emerges from early childhood and through to adolescence. This study tested sexual orientation disparities in the developmental trajectories of emotional and behavioral difficulties from ages 5...

We tested whether sexual orientation disparities in depressive symptoms are partially explained by a path through attachment anxiety or avoidance leading to ineffective coping strategies. A convenience sample of 1290 individuals from two reliable data collection platforms (Credamo and Wenjuanxing) in China were included. Structural equation modelin...

This study tested whether sexual orientation differences in depressive symptoms were partially explained by the chain mediation effect of neuroticism and victimization. Using the Avon Longitudinal Study of Parents and Children from the UK (N = 4647, 36.52% men, 88% White), self-reported neuroticism, sexual orientation, and depressive symptoms were...

Purpose: This study tested whether sexual orientation disparities in depressive symptoms are partially explained by recalled childhood gender nonconformity and whether the proportion of this association explained by childhood gender nonconformity is moderated by recalled parental attitudes toward childhood gender nonconformity. Methods: A convenien...

The mechanisms underlying sexual orientation differences in psychopathology originating in childhood remain understudied since sexual orientation does not directly manifest in childhood. This study tested whether childhood gender nonconformity and parental maltreatment before age 6 years 9 months partly explained sexual orientation disparities in t...

Abstract Purpose This study tested differences between youths who reported being heterosexual at ages 15.5 and 21, and those who changed from reporting being heterosexual at age 15.5 to nonheterosexual at age 21, in the developmental trajectories of depressive symptoms from age 22–24 years, and whether these longitudinal patterns were explained by...

We aimed to test whether asexual individuals were at increased risk of higher levels of depressive symptoms, self-harm attempts, and suicide attempts compared with heterosexual, bisexual, or gay/lesbian individuals using multivariate meta-analysis. Seventeen, five, and eight samples were included for depressive symptoms, self-harm attempts, and sui...

This study assesses the extent to which the association between erythrocyte sedimentation rate, a marker of inflammation, and cognitive function is explained by shared familial factors using within-sibling analyses. Men who were born in Sweden between 1950 and 1965 and recorded in the Swedish Military Conscription Register between 1969 and 1983 wer...

We aimed to test whether the association between same-sex marriage and common mental health diagnoses was explained by shared genetic and environmental familial influences using sibling comparison and adoption analyses. For the sibling comparison analysis, participants (1,177,712 men and 1,266,917 women) were individuals born in Sweden between 1932...

This study tested the influence of Deaf identity (cognitive identification and affective identification) on the association between perceived deaf discrimination and subjective well-being among Chinese adolescents who are deaf and hard-of-hearing (DHH), based on the rejection-identification model. Questionnaires on perceived deaf discrimination, su...

This study tested whether elevated risk of poorer mental health outcomes among nonheterosexual adolescents compared with heterosexual adolescents is plausibly explained by neuroticism and sexual orientation-based victimization. The Millennium Cohort Study, a large British prospective birth cohort, was used (4566 heterosexual boys, 77 bisexual boys,...

Background Advantages of robotic technique over laparoscopic technique in rectal tumor surgery have yet to be proven. Large multicenter, register-based cohort studies within an optimized perioperative care protocol are lacking. The aim of this retrospective cohort study was to compare short-term outcomes in robotic, laparoscopic and open rectal tum...

Purpose: We aimed to examine if same-sex partnership in men is associated with cardiovascular disease (CVD) and whether this relationship can be explained by accumulated risk factors in late adolescence using causal mediation analysis. Methods: All men born in Sweden between 1952 and 1956, who participated in mandatory Swedish military service cons...

Importance: Epstein-Barr virus and its acute manifestation, infectious mononucleosis (IM), are associated with an increased risk of multiple sclerosis (MS). Whether this association is confounded by susceptibility to infection is still debated. Objective: To assess whether hospital-diagnosed IM during childhood, adolescence, or young adulthood i...

This study tested adolescent sexual behavior patterns at age 14, their association with mental health at age 17 (psychological well-being, substance use, and self-harm attempts), and the influence of early life adversities upon this association. A British birth cohort (5,593 boys and 5,724 girls from the Millennium Cohort Study) was used. Latent cl...

Background This study aims to assess patient coverage, validity and data quality in the Swedish part of the International Enhanced Recovery After Surgery (ERAS) Interactive Audit System (EIAS). Method All Swedish ERAS centers that recorded colorectal surgery data in EIAS between January 1, 2017, and December 31, 2017, were included ( N = 12). Info...

The involvement of specific viral and bacterial infections as risk factors for multiple sclerosis has been studied extensively. However, whether this extends to infections in a broader sense is less clear and little is known about whether risk of a multiple sclerosis diagnosis is associated with other types and sites of infections, such as of the C...

Background Research on risk factors for anastomotic leakage (AL) alone within an Enhanced Recovery After Surgery (ERAS) protocol has not yet been conducted. The aim of this study was to identify risk factors for AL and study short-term outcome after AL in patients operated with anterior resection (AR). Methods All prospectively and consecutively r...

This study examined adolescent sexual behaviors patterns, and the consistency between sexual behavior and sexual orientation, in a prospective birth cohort. We used data on 5150 young people from the Avon Longitudinal Study of Parents and Children. Sexual orientation was assessed using a 5-point scale of sexual attraction at 15.5 years. Fourteen se...

Self-rated health (SRH) predicts mortality after adjustment for potential confounders, including measures of health status. Prodromal disease might lead to worsened SRH and higher mortality. But no study of SRH and mortality has focussed on inflammation. The objective of this study is to investigate the influence of inflammation upon the associatio...

Background Evidence for the association between body mass index (BMI) and multiple sclerosis (MS) among men remains mixed. Objective and methods Swedish military conscription and other registers identified MS after age of 20 years and BMI at ages 16–20 years (N = 744,548). Results Each unit (kg/m²) BMI increase was associated with greater MS risk...

The prevalence of women’s and men’s heterosexuality, bisexuality, and homosexuality was assessed in 28 nations using data from 191,088 participants from a 2005 BBC Internet survey. Sexual orientation was measured in terms of both self-reported sexual identity and self-reported degree of same-sex attraction. Multilevel modeling analyses revealed tha...

A cross-sex shift model of human sexual orientation differences predicts that homosexual men should perform or score in the direction of heterosexual women, and homosexual women in the direction of heterosexual men, in behavioral domains such as cognition and personality. In order to test whether homosexual men and women’s cognitive performance was...

This study tested whether previously reported associations between early life factors and later adolescent sexual orientation could be replicated in another prospective birth cohort, the UK Millennium Cohort Study (MCS). We used data on 9795 youth from the MCS. Emerging sexual orientation was assessed using measures of sexual attraction to males an...

We examined the sexual motives underlying sexual self-labels among Chinese men who have sex with men. A total of 60 bottoms, 120 versatiles, and 48 tops participated in a Web-based survey. Our results showed that tops were more likely to desire exerting power over their partners during sex, while bottoms were more likely to desire being overpowered...

A cross-sex shift model of human sexual orientation differences predicts that homosexual men should perform or score in the direction of heterosexual women, and homosexual women in the direction of heterosexual men, in behavioral domains such as cognition and personality. In order to test whether homosexual men and women’s cognitive performance was...

Measures of sexual interest tend to be more gender-specific in heterosexual men than in heterosexual women. Cognitive measures, such as viewing time to attractive stimuli, may also show similar patterns of gender-specificity or nonspecificity among men and women and thus serve as useful adjuncts to more direct measures of sexual interest. The objec...

The cross-sex-shift hypothesis predicts that homosexual men and women will be similar in certain neurobehavioral traits to their opposite-sex counterparts. Accordingly, it predicts that homosexual men should perform in the direction of heterosexual women, and homosexual women in the direction of heterosexual men, on neurocognitive tests that show n...

Background Social attitudes toward male homosexuality in China so far are still not optimistic. Sexual minorities in China have reported high levels of internalized homophobia. Methods This Internet-based study examined the associations among internalized homophobia, mental health, sexual behaviors, and outness among 435 gay/bisexual men in Southw...

In heterosexual individuals, attention is automatically captured by physically attractive members of the opposite sex. Although helpful for selecting new mates, attention to attractive relationship alternatives can threaten satisfaction with and commitment to an existing romantic relationship. The current study tested the hypothesis that although a...

Introduction: Previous studies have indicated that viewing sexually explicit media (SEM) might be associated with sexual risk behaviors in men who have sex with men (MSM). However, most prior research has not explored this association cross-culturally or the potential influence that important covariates might have on the association. Aim: To exp...

We examined the relationship between handedness, fraternal birth order, and sexual orientation in a Chinese population, and analyzed the influence of the components assessing sexual orientation and criteria classifying individuals as homosexual on this relationship. A large sample of heterosexual, bisexual, and homosexual men and women participated...

Research suggests that there is a relation between childhood sexual abuse (CSA) and adulthood nonheterosexual orientation. To explore whether nonheterosexual orientation increases the risk of CSA, we recruited a large sample, added the variable of childhood gender nonconformity (CGNC), and applied the instrumental variable method. We found that het...

We examined the relationship between 2D:4D digit ratio and sexual orientation in men from China and analyzed the influences of the components used to assess sexual orientation and the criteria used to classify individuals as homosexual on this relationship. A total of 309 male and 110 female participants took part in a web-based survey. Our results...

In order to determine the prevalence of childhood sexual abuse among gay, lesbian, and bisexual individuals, we conducted a meta-analysis that compiled the results of 65 articles across 9 countries. The results revealed no significant difference in the prevalence of child sexual abuse between homosexual and bisexual people for both sexes. The preva...
