Hi everyone

I am creating this thread as an archive thread just for statistics and polling links and information that we can all access and refer to. With the option for saving threads so we can find them easily, I figure it is a good way to gather specific types of information into one place.

Please post studies, papers, media articles that pull together references, or informative articles, tweets, videos, and interviews. Just on statistics and polling about the topic of Sex & Gender. Please post with a summary of the article, study, papers, etc so people can also use Advanced Search to locate the information and it will make it easier to read through to find the information again too.

I don't want to be the thread police, but ask that we keep this free of discussion. Getting into discussion on this thread will mean it will fill up quickly and not serve the purpose of being simply an archive.

Can I ask that if you want to discuss something you see here, you start a thread to do so and link and refer to a post on this thread? If a post has been presented with commentary that people disagree with, can that be discussed on a new thread please..

Keep this thread free just for the information.

Here is the link to the previous Break it down for me thread and the new General Break it Down archive thread.

The specific archive threads (including this one) are:

Long-Term Follow-Up of Transsexual Persons Undergoing Sex Reassignment Surgery: Cohort Study in Sweden
Cecilia Dhejne, Paul Lichtenstein, Marcus Boman, Anna L. V. Johansson, Niklas Långström, Mikael Landén

https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0016885

Context
The treatment for transsexualism is sex reassignment, including hormonal treatment and surgery aimed at making the person's body as congruent with the opposite sex as possible. There is a dearth of long term, follow-up studies after sex reassignment.
Objective
To estimate mortality, morbidity, and criminal rate after surgical sex reassignment of transsexual persons.
Design
A population-based matched cohort study.
Setting
Sweden, 1973-2003.
Participants
All 324 sex-reassigned persons (191 male-to-females, 133 female-to-males) in Sweden, 1973–2003. Random population controls (10∶1) were matched by birth year and birth sex or reassigned (final) sex, respectively.
Main Outcome Measures
Hazard ratios (HR) with 95% confidence intervals (CI) for mortality and psychiatric morbidity were obtained with Cox regression models, which were adjusted for immigrant status and psychiatric morbidity prior to sex reassignment (adjusted HR [aHR]).
Results
The overall mortality for sex-reassigned persons was higher during follow-up (aHR 2.8; 95% CI 1.8–4.3) than for controls of the same birth sex, particularly death from suicide (aHR 19.1; 95% CI 5.8–62.9). Sex-reassigned persons also had an increased risk for suicide attempts (aHR 4.9; 95% CI 2.9–8.5) and psychiatric inpatient care (aHR 2.8; 95% CI 2.0–3.9). Comparisons with controls matched on reassigned sex yielded similar results. Female-to-males, but not male-to-females, had a higher risk for criminal convictions than their respective birth sex controls.
Conclusions
Persons with transsexualism, after sex reassignment, have considerably higher risks for mortality, suicidal behaviour, and psychiatric morbidity than the general population. Our findings suggest that sex reassignment, although alleviating gender dysphoria, may not suffice as treatment for transsexualism, and should inspire improved psychiatric and somatic care after sex reassignment for this patient group.

INDEPENDENT REVIEW OF WPATH SOC GUIDELINES

https://link.springer.com/article/10.1007/s10508-025-03399-6

Quality of the World Professional Association for Transgender Health Guideline Standards of Care 8: An Appraisal Using the AGREE II Instrument

Conclusion

Our assessment revealed that WPATH’s SOC8 guidelines have limitations in scientific and methodological rigor, applicability, and transparency in managing competing interests. Evidence-based guidelines addressing the needs of transidentified children and adolescents are urgently needed, but the uncritical adoption or endorsement of WPATH’s guidelines may result in a disservice or even harm to this vulnerable population. It is imperative that healthcare providers, researchers, and policymakers recognize and address the limitations of WPATH’s SOC8.

Here is a tweet about the review from Ray Yuan Zhang

x.com/real_yuanzhang/status/2027058245576143312?s=46

WPATH guidelines are not evidence-based.

This week, our study assessing the methodological quality of the WPATH guidelines was published. We invited a group of healthcare professionals, including six physicians and two methodologists, to evaluate the guidelines using AGREE II. (AGREE II is the most widely used tool for assessing guideline quality. It examines 23 items across six domains related to rigor, applicability, editorial independence, and overall development quality.)

We selected reviewers with open minds and diverse expertise who are committed to evidence-based medicine. They are not inherently opposed to transition; if evidence shows that the benefits outweigh the risks, they would support such treatments. We also provided training on evidence-based medicine, guideline development, and the use of AGREE II.

The results indicate serious limitations in the WPATH guidelines, particularly in applicability, rigor of development, and editorial independence. The low score in rigor of development is especially concerning. This domain includes items such as "whether the strengths and limitations of the evidence are clearly described" and "whether there is an explicit link between recommendations and supporting evidence". A low score suggests that the guideline does not clearly demonstrate how the evidence supports its recommendations. The recommendations may be correct or incorrect, but the evidence basis is not transparently presented.

If you are interested in reading our study: link.springer.com/article/10.100…

As we concluded: “Evidence-based guidelines addressing the needs of trans-identified children and adolescents are urgently needed, but the uncritical adoption or endorsement of WPATH’s guidelines may result in a disservice or even harm to this vulnerable population. It is imperative that healthcare providers, researchers, and policymakers recognize and address the limitations of WPATH’s SOC8.”

The goal is not to dismiss care needs, but to provide the best possible help to those in need. If recommendations are developed with poor methodological quality, the guidelines cannot be truly helpful.

Gender Identity Disorders Among Young People in Germany:
Prevalence and Trends, 2013–2022 (2024)

https://api.aerzteblatt.de/pdf/di/121/11/m370.pdf

Results
In the period 2013–2022, the prevalence of as confirmed coded F64 diagnoses among insured persons aged 5 to 24years increased from 22.5/100 000 to 175.7/100 000 (M1Q) and from 15.2/100 000 (M2Q) to 132.6/100 000, respectively. The prevalence of the diagnose F64.0 was fairly constant (range: 70.2% to 78.5%). At the same time, the prevalence of F66 diagnoses declined from 216.7/100 000 to 73.7/100 000 (M1Q) and from 37/100 000 to 19.4/100 000 (M2Q), respectively. Looking at the two diagnoses (F64/F66) in conjunction, a clear increase in prevalence is noted when the M2Q criterion is applied. Applying M2Q, the prevalence increases from 51.9/100 000 to 149.8/100 000, while in M1Q hardly any changes are observed (compare Figure 1).

In almost all years, the highest prevalence of F64 diagnoses (M1Q) was noted among female adolescents in the age group 15 to 19 years (2022: 452.6/100 000, Figure 2). This finding was also observed for F66 (2022:191.5/100 000). In 72.4% of the persons with an F64 diagnosis in 2022 (n = 24 624), at least one additional psychiatric diagnosis was coded (males: 67.3%; females: 75.6%). The most common diagnoses were depressive disorders (males: 49.3%, females: 57.5%), anxiety disorders (23.5%/34.0%), emotionally unstable personality disorder of the borderline type (12.1%/17.6%), attention-deficit/hyperactivity disorders (12.7%/12.6%), and post-traumatic stress disorders (9.9%/13.6%)..

In the longitudinal cohort (n = 7885, 47.1% in the age group 20–24 years; 37.7% male), only 36.4% still had a confirmed F64 diagnosis after five years and diagnosis
persistence was below 50% in all age groups (range 27.3% [15–19-year-old females] to 49.7% [20–24-year-old males]).

Apologies if it's already been shared, but this review is very good. I shared it with my MP on the lobby day.

Psychiatric Morbidity Among Adolescents and Young Adults Who Contacted Specialised Gender Identity Services in Finland in 1996–2019: A Register Study

Sami-Matti Ruuska, Katinka Tuisku, Timo Holttinen, Riittakerttu Kaltiala

First published: 04 April 2026

ABSTRACT

Aim
To examine the prevalence of severe psychiatric morbidity among gender-referred adolescents, focusing on gender differences and outcomes related to medical gender reassignment.

Methods
Finnish nationwide cohort of all under-23-year-old gender-referred individuals between 1996 and 2019 (n = 2 083) and 16 643 matched controls. Cross-tabulations with X2 statistics and Cox regression were used to analyse the data.

Results
Gender-referred adolescents showed significantly higher psychiatric morbidity than controls both before (45.7% vs. 15.0%) and ≥ 2 years after referral (61.7% vs. 14.6%). Those referred after 2010 had greater psychiatric needs than earlier cohorts, both before (47.9% vs. 15.3%) and ≥ 2 years after (61.3% vs. 14.2%) referral. Among adolescents who underwent medical gender reassignment, psychiatric morbidity increased markedly during follow-up—rising from 9.8% to 60.7% in feminising gender reassignment and from 21.6% to 54.5% in masculinising gender reassignment. After adjusting for prior psychiatric treatment, all gender-referred adolescents had similarly elevated risks of psychiatric morbidity, with hazard ratios approximately three times higher than female controls and five times higher than male controls.

Conclusion
Severe psychiatric morbidity is common among gender-referred adolescents and appears to be more prevalent in those referred after the recent surge in referrals. Psychiatric needs do not subside after medical gender reassignment.

Summary

-Gender-referred adolescents show high psychiatric morbidity, yet gender differences and mental health trajectories after medical gender reassignment remain poorly understood.

-These adolescents had markedly higher psychiatric morbidity than controls before and after referral, with treatment needs often persisting and even intensifying after medical interventions—on some, they might even have a negative impact.

-Findings emphasise the need for thorough psychiatric assessment and ongoing treatment throughout medical gender reassignment.

Just pulling this out.

After adjusting for prior psychiatric treatment, all gender-referred adolescents had similarly elevated risks of psychiatric morbidity, with hazard ratios approximately three times higher than female controls and five times higher than male controls.
