まとめ
ジェンダー・ディスフォリア (GD) の個人は,高い安定率で,合法的なジェンダー変更が一般的です. この研究では 法的性別の変化の98%近くが 10年以上にわたって安定していることが判明し めったに逆転しないことを示しています
科学分野:
- 内分泌学と代謝
- 公衆衛生と疫学
- 精神医学と心理学
背景:
- ジェンダー・ディスフォリア (GD) 診断の普及が増加しているため,移行結果を理解することが必要になります.
- 移行,特に法的ジェンダーの逆転に関するデータは限られている.
- 法律上の性別変更登録は 移行の安定性についての洞察を与えてくれます
研究 の 目的:
- GDと診断された個人の合法的な性別変更の確率を決定する.
- 法的なジェンダーの変化の長期的安定性を評価する.
- 法律上のジェンダーの逆転を 移行の潜在的指標として分析する.
主な方法:
- スウェーデンの国家登録を活用した人口ベースのコホート研究 (2013-2023)
- GDのICD-10診断コードを初めて持っている個人を含む.
- カプラン・メイヤー生存分析法による性別変化と安定性の確率を計算する.
主要な成果:
- GDの診断を受けた7293人; 女性の3分の1は 合法的な性別転換を成し遂げました
- 10年間の合法的な性別変更の確率は58.3%でした.
- 10年間の法的ジェンダー安定率は97.7%で,法的なジェンダーの逆転は21件のみでした.
結論:
- スウェーデンのGD患者の多くは 合法的な性別転換を経験しています
- 法律上のジェンダーの変化は10年以上にわたって高い安定性を示しています.
- 法律上のジェンダーの逆転は全国的なサンプルではめったに起こらず,法律上のジェンダーの変化の結果が堅実であることを示唆しています.

Socioemotional Experience and Gender Development
77
Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...

Ethnic Identity within a Larger Culture
85
Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

Menopause
248
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Psychosexual Stages of Personality: Latency
667
Following the phallic stage in Freud's theory of psychosexual development, children enter a phase called the latency period, which lasts from approximately six to twelve years of age. Unlike earlier stages, where sexual impulses played a central role, Freud believed these impulses are repressed during the latency period, becoming part of the unconscious. This stage is often described as a time of psychological calm after the turbulence of the phallic stage.

Psychosexual Stages of Personality: Genital
987
The genital stage is the final phase of Sigmund Freud's theory of psychosexual development, beginning at puberty, around age 12. During this stage, sexual energy shifts from self-focused interests to external individuals, marking the development of mature adult sexuality. Freud saw this phase as a time of sexual reawakening, with desires directed toward others outside the family. A healthy transition into this stage, according to Freud, signifies the emergence of two key aspects of adult...

Erikson's Theory on Socioemotional Development during Adulthood
268
Erik Erikson's theory of psychosocial development outlines a series of stages through which individuals progress across the lifespan. Each stage involves a psychosocial conflict that significantly influences personal growth and well-being. Three key stages — intimacy versus isolation, generativity versus stagnation, and integrity versus despair — highlight the developmental challenges faced in adulthood.
