Social transition, socioeconomic status and self-rated health in China: evidence from a national cross-sectional survey (CGSS).

Background: Social transition is one of the multi-level mechanisms that influence health disparities. However, it has received less attention as one of the non-traditional social determinants of health. A few studies have examined China's social transition and its impact on health inequality in self-rated health (SRH). Therefore, this study explores the impact of China's market-oriented reforms-social transition and socioeconomic status (SES)-on residents' SRH. Methods: Using the cross-sectional data from the Chinese General Social Survey (CGSS) in 2017, we analyzed the effects of social transition and SES on the SRH of Chinese residents using the RIF (Recentered influence function) method. The RIF decomposition method investigated health differences among different populations and their determinants. Results: Social transition and SES have significant positive effects on the SRH of Chinese residents. The correlation between SES and the SRH of Chinese residents is moderated by social transition, implying that social transition can weaken the correlation between SES and the SRH of Chinese residents. The impacts of SES and social transition on SRH vary across populations. Conclusion: Promoting social transition and favoring disadvantaged groups with more resources are urgently needed to promote equitable health outcomes.

Exploring navigation of gender in a sample of clinically referred young people attending the gender identity development service.

BACKGROUND: Gender-diverse young people experience a cisnormative world and are subject to unique minority stressors, which have been found to contribute to adverse mental health. This research aims to understand the social and personal context unique to gender-diverse people that young people navigate prior to attending specialised services. METHODS: The baseline measure of a newly developed questionnaire, the GIDS Gender Questionnaire (GIDS-GQ), was sent to all young people (or caregivers for those aged under 12) attending the Gender Identity Development Service (GIDS). Eighty-four young people and caregivers completed the questionnaire, with eighty-one included in the final sample (M = 15.77 years, SD = 1.83, range = 9-17; assigned female at birth = 72, assigned male at birth = 9). Questionnaires were emailed to participants via an online survey between one and three appointments with the Service. Data were collected between April 2021 and February 2022. RESULTS: All young people had initiated a social transition, with 75.3% categorised as fully socially transitioned. More young people reported experiencing transphobic bullying (64.2%) and a lack of acceptance of their gender identity (85.1%) in the past (lifetime) than in the 6 months prior to attending the service (transphobic bullying: 12.3%; non-acceptance: 49.4%). 94.5% of the sample reported disliked body parts, most commonly breasts (80.8%), genitals (37%), and hips (31.5%). Participants most commonly reported a decrease in their mood (61.25%) and most areas of social connectedness. CONCLUSIONS: The majority of this sample had socially transitioned, were supported in their identification, and had experienced less transphobic bullying and non-acceptance prior to commencing services. However, young people continued to dislike their bodies, and experience low mood and social connectedness. Future research is needed to understand how clinical support can help reduce the impact of these external/distal minority stressors by promoting social connectedness, incorporating such learnings into clinical practice and subsequent policy in clinical work with gender-diverse young people.

[Benefits of early social transition in transgender minors. Family perspectives: qualitative study.] / Beneficios de la transición social temprana en menores transgénero. Perspectivas de familias: estudio cualitativo.

OBJECTIVE: The term trans brings together all transgender identities. The early social transition towards the affirmed gender has benefits in the child's development. For families, transit is a period of great uncertainty, requiring support aimed at families of trans minors. The aim of this paper was to explore the needs and experiencies of parents and close-relatives who supported the social transition of their children. METHODS: We worked with focus groups of functional families of transgender minors who had begun the transition (n=14), with a medium-high educational level and who belonged to urban areas of Tenerife. Through a semi-structured interview, they commented on their experiences in the process of supporting the social transition of their children. The data was recorded in a video recording and processed through content analysis and categorization. RESULTS: Early social transition had positive and immediate benefits on child development as well as in the reduction of anxiety. There was a general improvement in mood, self-esteem, and social and family relationships. The accompaniment of specialists and associations helped in the different social situations and favoured resilience. CONCLUSIONS: Early social transition is positive in the personal and socio-family sphere of the minor. To improve their resilience, families demand accompaniment in this process, as well as meeting other trans people who serve as transpositive references. In addition, they point out the need for specific training in health professionals.

OBJETIVO: El término trans aglutina a todas las identidades transgénero. La transición social temprana hacia el género sentido tiene beneficios en el desarrollo del menor. Para las familias, el tránsito es un periodo de grandes incertidumbres, siendo necesario el acompañamiento dirigido a las familias de menores trans. El objetivo del artículo fue explorar, desde una perspectiva paterna y familiar, las necesidades y experiencias sobre el tránsito de menores trans que sirvieran de referente a otros padres/madres que apoyan el tránsito social de sus hijos e hijas. METODOS: Se trabajó con grupos focales de familias funcionales de menores transgénero que habían iniciado la transición (n=14), de nivel educativo medio-alto y que pertenecían a zonas urbanas de Tenerife. Mediante entrevista semiestructurada, comentaron sus experiencias en el proceso de dar soporte al tránsito social de sus hijos e hijas. Los datos fueron registrados en una videograbación y se procesaron mediante análisis de contenido y categorización. RESULTADOS: La transición social temprana tuvo beneficios positivos e inmediatos en el desarrollo del menor, además de en la disminución de la ansiedad. Hubo una mejora general en el humor, la autoestima y las relaciones tanto sociales como familiares. El acompañamiento de especialistas y asociaciones ayudó en las distintas situaciones sociales y favoreció la resiliencia. CONCLUSIONES: El tránsito social temprano es positivo en la esfera personal y sociofamiliar del menor. Para mejorar su resiliencia, las familias demandan acompañamiento en este proceso, así como conocer otras personas trans que les sirvan como referentes transpositivos. Además, señalan la necesidad de formación específica en los profesionales sanitarios.

Retransitioning: The experiences of youth who socially transition genders more than once.

Background: Retransitions in youth are critical to understand, as they are an experience about which little is known and about which families and clinicians worry. Aims: This study aims to qualitatively describe the experiences of youth who made binary social transitions (came to live as the binary gender different from the one assigned at birth) in childhood by the age of 12, and who later socially transitioned genders again (here, called "retransitioning"). Methods: Out of 317 participants in an ongoing longitudinal study of (initially) binary transgender youth, 23 participants had retransitioned at least once and were therefore eligible for this study. Of those youth, 8 were cisgender at the time of data collection, 11 were nonbinary, and 4 were binary transgender youth (after having retransitioned to nonbinary identities for a period). Fifteen youth and/or their parent(s) participated in semi-structured interviews (MYouthA ge = 11.3 years; 9 non-Hispanic White; 3 Hispanic White; 3 Multiracial; 10 assigned male; 5 assigned female). Interviews gauged antecedents of transitions, others' reactions to transitions, and participants' general reflections. Responses were coded and thematically analyzed. Results: Participants described various paths to retransitions, including that some youth identified differently over time, and that some youth learned about a new identity (e.g., nonbinary) that fit them better. Social environments' responses to retransitions varied but were often neutral or positive. No participants spontaneously expressed regret over initial transitions. Conclusions: These findings largely do not support common concerns about retransitions. In supportive environments, gender diverse youth can retransition without experiencing rejection, distress, and regret.

Transgender identity: Development, management and affirmation.

In this review, I discuss recent research on transgender identity development, management and affirmation, situating key topics within a social feedback model of transgender identity. This model foregrounds the dynamic interplay between internal and external influences on transgender identity. Furthermore, issues of intersectionality are highlighted throughout and located within broader socio-political contexts. Collectively, research on topics such as gender euphoria, passing, identity affirmation and social transitions, among others, points to the pivotal role of supportive social relationships and social environments in the healthy development and expression of transgender identities. Future work should prioritize longitudinal studies with careful and rigorous assessment of identity-related constructs in order to further examine these and other topics.

Differences in self-perception and social gender status in children with gender incongruence.

Background: Gender incongruent children report lower self-perception compared to the norm population. This study explored differences in self-perception between children living in their gender role assigned at birth and children living in their experienced gender role.Method: The self-perception questionnaire was administered to 312 children referred to the Center of Expertise on Gender Dysphoria 'Amsterdam UMC'. Social transition status was determined by parental interviews. 2 (social transition) by 2 (sex assigned at birth) ANCOVA's were conducted.Results: Children living in their assigned gender role reported comparable self-perception to children living in their experienced gender role. Birth assigned girls living in their assigned gender role reported poorer self-perception on 'athletic competence', compared to girls living in their experienced gender role. Birth assigned boys living in their assigned gender role reported poorer on 'scholastic competence' and 'behavioral conduct' compared to boys living in their experienced gender role.Conclusions: Social transition did not show to affect self-perception. Self-perception was poorer for birth assigned boys living in their experienced gender role. For birth assigned girls this was reversed. Future studies should give more insight in the role of social transitions in relation to child development and focus on other aspects related to self-perception.

Early queen joining and long-term queen associations in polygyne colonies of an invasive wasp revealed by longitudinal genetic analysis.

Invasive social insects rank among the most damaging of terrestrial species. They are responsible for extensive damage and severely threaten the biodiversity of environments where they are introduced. Variation in colony social form commonly occurs in introduced populations of yellowjacket wasps (genus Vespula). In particular, invasive colonies may contain multiple queens (i.e., polygyne) and persist several years, while in the native range, the colonies are usually annual and harbor a single queen (i.e., monogyne). In this study, we used genome-wide loci obtained by double digest restriction site-associated DNA sequencing (RADseq) to investigate the genetic structure and queen turnover in colonies of the western yellowjacket, Vespula pensylvanica, in their introduced range in Hawaii. Of the 27 colonies monitored over four months (October-January), 19 were polygyne and already contained multiple queens on the first day of sampling. Contrary to previous speculation, this finding suggests that polygyny often arises early in the annual colony cycle, before the production of new queens in the fall. Furthermore, polygyne colonies exhibited a prolonged average lifespan relative to those headed by a single queen. As a result, there is no clear window during which colony eradication efforts would be more effective than upon first discovery. The relatedness among nestmate queens was slightly above zero, indicating that these colonies are generally composed of nonrelatives. The queen turnover within each colony was low, and we detected some full-sibling workers sampled up to four months apart. Finally, we did not detect any population structure among colonies, suggesting that queens disperse up to several kilometers. Taken together, our results provide the first insights into the requeening dynamics in this invasive and incipiently polygyne population and illuminate the early establishment of multiple long-lasting queens in these damaging colonies.

Timing of Social Transition for Transgender and Gender Diverse Youth, K-12 Harassment, and Adult Mental Health Outcomes.

PURPOSE: Many transgender and gender diverse (TGD) youth undergo a social transition in which they change their gender expression to align with their gender identity. Our objective was to examine associations between timing of social transition (during the prepubertal childhood period, adolescence, or adulthood) and adult mental health outcomes. METHODS: We conducted a secondary analysis of the 2015 U.S. Transgender Survey, a cross-sectional nonprobability survey of 27,715 TGD adults in the United States. Based on self-reports, participants were categorized as having undergone social transition during childhood (ages 3-9 years), adolescence (ages 10-17 years), or adulthood (ages ≥18 years). Using multivariable logistic regression, we examined associations between timing of social transition and adult mental health outcomes. RESULTS: After adjusting for demographic and potential confounding variables, childhood social transition was associated with lower odds of lifetime marijuana use (adjusted odds ratio .7, 95% confidence interval = .5-.8, p < .0001) when compared with adult social transition. Before adjusting for K-12 harassment based on gender identity, adolescent social transition was associated with adverse mental health outcomes, including greater odds of lifetime suicide attempts when compared with adult social transition (adjusted odds ratio 1.3, 95% confidence interval = 1.1-1.7, p = .004). These associations were no longer significant after further adjusting for K-12 harassment. CONCLUSIONS: Although past research has shown TGD youth who undergo social transition have favorable mental health outcomes in the short term, they may have worse mental health in adulthood if not protected from K-12 harassment based on gender identity. It is the responsibility of clinicians to emphasize the importance of adolescents having safe and affirming social environments.

[Support for transgender adolescents and preadolescents: the role of the pediatric endocrinologist]. / Rôle de l'endocrino-pédiatre dans l'accompagnement des adolescents et préadolescents transgenres.

Since the end of the 1990s, the management of transgender adolescents has developed in many countries following the Dutch Approach initiated in the Netherlands. Dedicated consultations have been developed in France since 2013, welcoming a growing number of children and adolescents. What kind of support is offered to children and their families?

Transición social en niñas, niños, niñes y adolescentes con incongruencia de género: revisión y sugerencias de intervención a profesionales / Social transition in children and adolescents with gender incongruence: review and intervention recommendations for professionals

Introducción: la transición social en niñas (os, es) y adolescentes con incongruencia de género, es una intervención no médica, com-pletamente reversible, que genera beneficios en la salud mental, pero que ha sido poco estudiada. El objetivo es realizar una revisión bibliográfica al respecto y desde ahí derivar recomendaciones a las(os) profesionales que intervienen en el apoyo a estas (os, es) niñas (os, es), adolescentes y sus familias. Métodos: ll presente trabajo corresponde a una revisión entre los años 2010 ­ 2021 en revistas científicas en habla inglesa e hispana indexadas en PUBMED, SciELO y en Google Académico. Resultados: se describe la trayectoria en el desarrollo de la incongruencia de género. En las (os, es) prepúberes el interés está centrado en la persistencia y desistencia de la incongruencia de género y las distintas trayectorias. La transición social y la persistencia se pueden manifestar diferencialmente para niñas y niños trans. Realizar transición social en niñas (os, es) que lo solicitan favorece la salud mental. La familia y la comunidad viven sus propias transiciones. En Chile se han ido dando las condiciones en salud, educación y a nivel legislativo para apoyar la afirmación de género de las niñas (os, es) y adolescentes, pero falta educación respecto a la transición social en infancia y adolescencia. Conclusiones:dado los beneficios que genera la transición social en niñas (os, es) y adolescentes transgénero, se requiere que las(os) profesionales se eduquen e intervengan adecuadamente.

Introduction: Social transition for boys, girls, and adolescents with gender incongruence is a completely reversible non-medical inter-vention that generates important mental health benefits, but reviews lack studies. The objective here is to do a bibliographic review regarding the matter, and from there, formulate recommendations for professionals who intervene to support these boys, girls, and adolescents, as well as their families. Method:This work reviews English and Spanish journals, published between 2010 and 2020, indexed in PUBMED, SciELO, and Google Scholar.Results: The trajectory of the development of gender incongruence is described. For children in the ́re-puberty stage, the interest is focused on the persistence and desistence of gender incongruence. Social transition and persistence can manifest differentially for trans boys and trans girls. Making a social transition for the boys and girls who request it benefits their mental health. The family and the community undergo their transformations. In Chile, conditions at a health, education, and legislative level, to support the gender affirmation of boys, girls and adolescents, have appeared. Still, there is a lack of education regarding the social transition in childhood and adolescence.Conclusions: Given the benefits that social transition generates for trans-gender boys, girls, and adolescents, it is required that professionals educate themselves and intervene accordingly.

Not social transition status, but peer relations and family functioning predict psychological functioning in a German clinical sample of children with Gender Dysphoria.

Research provides inconclusive results on whether a social gender transition (e.g. name, pronoun, and clothing changes) benefits transgender children or children with a Gender Dysphoria (GD) diagnosis. This study examined the relationship between social transition status and psychological functioning outcomes in a clinical sample of children with a GD diagnosis. Psychological functioning (Child Behavior Checklist; CBCL), the degree of a social transition, general family functioning (GFF), and poor peer relations (PPR) were assessed via parental reports of 54 children (range 5-11 years) from the Hamburg Gender Identity Service (GIS). A multiple linear regression analysis examined the impact of the social transition status on psychological functioning, controlled for gender, age, socioeconomic status (SES), PPR and GFF. Parents reported significantly higher scores for all CBCL scales in comparison to the German age-equivalent norm population. Peer problems and worse family functioning were significantly associated with impaired psychological functioning, whilst the degree of social transition did not significantly predict the outcome. Therefore, claims that gender affirmation through transitioning socially is beneficial for children with GD could not be supported from the present results. Instead, the study highlights the importance of individual social support provided by peers and family, independent of exploring additional possibilities of gender transition during counseling.

Bioarchaeological reconstruction of physiological stress during social transition in Albania.

OBJECTIVE: We test the hypothesis that physiological stress increased in response to increasing social turmoil following waves of colonization and social transition. The ways local conditions, including variation in geography, environment, and levels of urbanization impact physiological stress are also explored. MATERIALS: In Albania, the historic period is a sequence of different waves of colonization. Skeletal data come from three Albanian archaeological sites: Apollonia (n = 231), Durrës (n = 246), and Lofkënd (n = 129). METHODS: Prevalence of cribra orbitalia, porotic hyperostosis, linear enamel hypoplasia, and periosteal new bone formation are analyzed using chi-square and logistic regression tests. RESULTS: We observe increased skeletal manifestations of physiological stress between prehistoric and historic groups, but physiological stress is generally consistent through time. CONCLUSIONS: General increase in skeletal pathology between prehistoric and historic periods corresponds to broad increases in political unrest associated with colonization spanning the entire historic period. However, little difference in physiological stress across colonization episodes (Greek, Roman, Byzantine, Bulgarian, Ottoman) suggests skeletal health is affected similarly by colonization, regardless of particularities in method and type of colonial control. SIGNIFICANCE: Examining human response to social change across broad time scales is useful in identifying broad patterns in the human experience. LIMITATIONS: Exploring variation across broad time scales and multiple sites is potentially problematic because confounding factors could impact results and interpretations. SUGGESTIONS FOR FURTHER RESEARCH: Environmental, social, and geographic differences, likely impacted the lives and lifestyles of individuals living in the past and should be explored further to understand the nuances in local response to colonization.

Social transition and health inequality in China: an age-period-cohort analysis.

OBJECTIVES: To examine self-rated health (SRH) trajectories by age, period and cohort in the dynamic environment of China and to focus on sex, educational, family economic status (FES) and regional disparities in these temporal trajectories. STUDY DESIGN: Repeated cross-sectional data from the World Value Survey from 1990 to 2012 (n = 7731) were used. METHODS: An age-period-cohort (APC) model with an intrinsic estimator method was applied, using SRH as a continuous variable to analyse SRH trajectories by age, period and cohort in different groups in China. Robust analyses were conducted using SRH as a binary variable and a hierarchical APC cross-classified random effects model. RESULTS: SRH was adversely associated with age, and a global trend of declining SRH was observed between 1990 and 2012; however, SRH generally increased across successive cohorts in China. SRH was better in males, individuals from the eastern region, and in those with higher levels of education and higher FES. Regional and FES disparities in SRH increased with age and across successive cohorts; however, educational disparities in SRH first decreased and then increased with age and across successive cohorts, and sex disparities in SRH decreased across successive cohorts, in general. CONCLUSIONS: A well-performing social environment is related to better population health. The cumulative disadvantage in health among individuals from underprivileged regions/families with less education should be the focus of social transition in China.

Cash support vs. tax incentives: The differential impact of policy interventions on third births in contemporary Hungary.

Following steep falls in birth rates in Central and Eastern European countries during the economic and institutional restructuring of the early 1990s, governments made substantial efforts to stop or at least reduce the fertility decline. In Hungary, parents with three or more children could benefit from specific new policy measures: the flat-rate child-rearing support paid from the youngest child's third to eighth birthdays (signalling recognition of stay-at-home motherhood) and a redesigned and upgraded tax relief system. However, the success of these policy measures, if any, is difficult to detect in aggregate statistics. Analysing data from the Hungarian Generations and Gender Survey, we rely on event history methods to examine the policies' effects on third birth risks, especially among different socio-economic groups. The results indicate that while the child-rearing support increased third birth risks among the least educated, the generous tax relief had a similar effect for parents with tertiary education.

Being Trans Without Medical Transition: Exploring Characteristics of Trans Individuals from Germany Not Seeking Gender-Affirmative Medical Interventions.

Until recently, trans persons were expected to align their sex characteristics as much as possible with the opposite sex. Today, research and health care, as well as the diagnostic criteria from DSM-5 and ICD-11, reflect a broader understanding of trans individuals. It encompasses diverse identities and treatment requests, including trans individuals not wanting or having decided against gender-affirmative medical interventions (GAMI). The present study explored this insufficiently studied group by (1) reviewing the existing literature regarding trans individuals not seeking GAMI and by (2) exploring their demographic and trans-related characteristics in a non-clinical online convenience sample from Germany. The literature review found one large survey with a single question on trans individuals not seeking GAMI. Beyond that, only community literature addressed the topic. The analyzed sample consisted of 415 trans participants, of whom 220 were assigned female at birth (AFAB) and 195 were assigned male at birth (AMAB). Fourteen (3.4%) reported neither previous nor planned GAMI (AFAB = 9, AMAB = 5). Trans individuals not seeking GAMI were significantly older and more often reported to identify with a non-binary gender. The two interdependent, central reasons for refusing GAMI were the avoidance of transition-related suffering and the lack of necessity for treatment. The diversification of gender, as reflected in the increasing visibility of non-binary or genderqueer gender identities, seems to go hand in hand with a diversification of transition-related treatment, including the option not to seek GAMI.

Transgender Students: Advocacy, Care, and Support Opportunities for School Nurses.

Transgender individuals are disproportionately affected by negative mental and sexual health outcomes. School nurses have prime opportunities to combat these outcomes through affirming nursing care, especially when transgender students are socially transitioning. Examples of affirming practice include recognizing students' gender-affirming names, using their pronouns, ensuring safe locker rooms, advocating for student's clothing choices, stopping bullying and harassment, and refraining from making assumptions about their transgender students' sexual orientation. Through inclusive care directly provided to transgender children, school nurses can also be instrumental in ushering an affirming environment for all.

Gender and social mobility modify the effect of birth weight on total and central obesity.

BACKGROUND: Little is known about the interaction between gender and low birth weight (LBW) and lifelong social mobility as an explanation of the etiology of obesity. The aim of the present study was to evaluate total and central obesity according to gender, LBW and social mobility, within the context of the epidemiological transition in middle-income countries. We hypothesize that there are more pronounced metabolic consequences of social mobility for women born with LBW. METHODS: We used data from a birth cohort study conducted in Ribeirão Preto, São Paulo, Brazil. Data regarding anthropometric measurements, schooling and smoking status were collected at 23-25 years of age. Social mobility was determined based on maternal and adult offspring schooling and categorized as Low-Low, Low-High and High-High. Analysis of covariance was performed to assess the association between social mobility and body mass index (BMI) or waist circumference (WC) in adulthood, stratified by LBW and gender. RESULTS: Data on 6827 singleton pregnancies were collected at birth in 1978/79 and a sample was followed up in 2002/04. A total of 2063 subjects were included in the study. Mean age was 23.9 ± 0.7 years, 51.8% (n = 1068) were female and the LBW was 6.2% (n = 128). There was a triple interaction between social mobility, LBW and gender. Among women born without LBW, BMI and WC were higher in the Low-Low group compared to High-High schooling group. Among LBW women, BMI and WC were higher in the Low-Low group compared to the Low-High group. CONCLUSIONS: Women born with LBW belonging to the low schooling group in early adulthood had high BMI and WC, compared to the Low-High social mobility group.

Strategy changes in subsequent fights as consequences of winning and losing in fruit fly fights.

In competition for food, territory and mates, male fruit flies (Drosophila melanogaster) engage in agonistic encounters with conspecifics. The fighting strategies used to obtain these resources are influenced by previous and present experience, environmental cues, and the internal state of the animal including hormonal and genetic influences. Animals that experience prior defeats show submissive behavior and are more likely to lose 2nd contests, while animals that win 1st fights are more aggressive and have a higher probability of winning 2nd contests. In a recent report, we examined these loser and winner effects in greater detail and demonstrated that both winners and losers show short-term memory of the results of previous bouts while only losers demonstrate a longer-term memory that requires protein synthesis. The recent findings also suggested that an individual recognition mechanism likely exists that can serve important roles in evaluating the fighting ability of opponents and influencing future fighting strategy. In this article, we follow up on these results by asking how previous defeated and victorious flies change their fighting strategies in the presence of 2nd losing and winning flies, by searching for evidence of territory marking, and discussing the existing literature in light of our findings.

Family Care of People with Intellectual Disability in Rural China: A Magnified Responsibility.

BACKGROUND: Welfare for the disabled is becoming an important issue in China and care for people with intellectual disability is challenging because of the inadequacies in formal support and the social service system. MATERIAL AND METHOD: Based on ethnographic research in two villages in North China, this paper analyses the dilemmas of family care for people with intellectual disability. The essential data is the ethnographic record of three cases. RESULTS: Rural families strive to provide care through a set of arrangements and bear tremendous stress in the process. CONCLUSION: Family care for people with intellectual disability in rural China has been increasingly challenged by the forces of labour migration, demographic changes and the ever-growing processes of commoditization. The role of the state has to be strengthened in welfare provision to balance the weakened family care ethos in transforming societies.
