Study links rising suicidality among teen girls to increase in identifying as LGBQ

Researchers suggest that a larger proportion of female students are experiencing the pressures felt by LGBQ youth

2025-01-16

(Press-News.org) Amid an increase in suicidal behavior among teen girls, new research links this phenomenon to the significant increase in the number of female students identifying as lesbian, gay, bisexual, or questioning (LGBQ).

“This finding suggests that the overall increase in female suicidality is not due to all female students becoming more suicidal, but rather to a larger proportion of students being part of a group that has historically experienced higher rates of suicidal thoughts and behaviors due to social and structural pressures,” says lead author Joseph Cimpian, professor of economics and education policy at NYU Steinhardt School of Culture, Education, and Human Development.

Using data from the U.S. Centers for Disease Control and Prevention’s biennial Youth Risk Behavior Survey, researchers analyzed trends in years 2015, 2017, 2019, and 2021 to examine how LGBQ identification and suicidality has changed among males and females (the binary categories used in the survey). From the sample of more than 44,000 students, they found that the percentage of high school females identifying as LGBQ more than doubled, rising from 15% in 2015 to 34% in 2021. During this same period, suicidal ideation among all female students increased from 23% to 29%, and suicide planning increased from 19% to 23%. Between 2017 and 2021, suicide attempts among female students increased from 10% to 13%.

The findings, published in Educational Researcher, revealed that LGBQ females consistently reported much higher rates of suicidal thoughts and behaviors—for example, in 2021, about 48% of LGBQ females considered suicide compared to roughly 20% of heterosexual females. The researchers used statistical methods that isolated identifying as LGBQ as a factor and found that it was directly correlated to the rise in overall suicidality among females.

In contrast, teenage boys showed different patterns. The percentage of males identifying as LGBQ increased only slightly, from 6% in 2015, to 9% in 2021, with correspondingly smaller changes in suicide-related outcomes.

The trends for females and males were consistent across both White and BIPOC (Black, Indigenous, and people of color) students.

“These findings highlight the critical need to address the structural and social pressures that LGBQ youth face, including in our schools,” says Cimpian. “LGBQ females across all racial and ethnic groups need educational supports to offset the risk of suicidality. Rather than reducing resources for LGBQ youth, as many recent state bills propose, policymakers and practitioners interested in decreasing suicidality among females should target additional educational and mental health resources to support LGBQ students.”

Mind’s eye: Pineal gland photoreceptor’s 2 genes help fish detect color

2025-01-16

We see color because photoreceptor cones in our eyes detect light waves corresponding to red, green, and blue, while dimness or brightness is detected by photoreceptor rods. Many non-mammalian vertebrates like fish, however, are known to detect color and brightness with the pineal gland, which is part of the brain. An Osaka Metropolitan University research group has further elucidated on how the pineal organ of fish do so. Previously, the research group led by Professor Akihisa Terakita and Professor Mitsumasa Koyanagi of the Graduate School of Science revealed that ...

Nipah virus: epidemiology, pathogenesis, treatment, and prevention

2025-01-16

Nipah virus (NiV), a zoonotic paramyxovirus with significant human health implications, has garnered considerable attention due to its high fatality rates and potential for human-to-human transmission, posing a global public health threat. Emerging in South and Southeast Asia, NiV is known for its recurrent outbreaks, with a particular focus on its genetic lineages, NiV-MY and NiV-BD, which differ in pathogenicity and transmissibility. The virus, initially isolated in Malaysia in 1998, has since caused outbreaks linked to contact with infected ...

FDA ban on Red Dye 3 and more are highlighted in Sylvester Cancer's January tip sheet

2025-01-16

FDA BANS RED DYE 3 IN FOOD AND INGESTED DRUGS Citing two studies linking Red Dye 3 to cancer in laboratory male rats, the FDA today revoked authorization for the use of the dye in food and ingested drugs. The move came in response to a 2022 color additive petition. “This is long overdue,” said Tracy Crane, Ph.D., RDN., director of Lifestyle Medicine and Prevention at Sylvester. “Red Dye 3 has been banned for use in cosmetics and topical drugs for more than three decades,” she said. “Yet it gives more than 9,000 foods in the United States their red coloring. These colorful foods and drinks are particularly appealing to young children,” ...

Mapping gene regulation

2025-01-16

KYOTO – An international team of researchers has taken an important step toward understanding how gene expression is controlled across the human genome. A new study has comprehensively analyzed “cis-regulatory elements” (CREs), which are the DNA sequences that regulate gene transcription. This work sheds light on how these elements contribute to cell-specific gene expression and how mutations within them may influence health and disease. CREs, including enhancers and promoters, are essential for controlling when and where genes are ...

Exposure to air pollution before pregnancy linked to higher child body mass index, study finds

2025-01-16

In a study of more than 5,000 mothers and their children, exposure to air pollution during the three months before pregnancy predicted higher child body mass index (BMI) and related obesity risk factors up to two years of age. Findings from the study, which was supported by the National Institute of Environmental Health Sciences, were published in the journal Environmental Research. Past research has linked air pollution exposure during pregnancy to a broad range of health problems in children, including respiratory ...

Neural partially linear additive model

2025-01-16

Interpretability has drawn increasing attention in machine learning. Partially linear additive models provide an attractive middle ground between the simplicity of generalized linear model and the flexibility of generalized additive model, and are important models for addressing the two interpretability problems of feature selection and structure discovery. The existing partially linear additive models still have various imperfect performances in terms of fitting ability. To solve the problems, a research team lad by Han LI published their new research on 15 December 2024 in Frontiers of Computer Science co-published by Higher Education Press and Springer Nature. The ...

Dung data: manure can help to improve global maps of herbivore distribution

2025-01-16

Researchers have used dung records to create high-resolution maps of herbivore distribution around the world. Their new study, recently published in Nature Food, reveals a strong positive relationship between dung presence and grazing pressure, meaning the amount of dung found in a particular location could help us understand approximately how many herbivores live there. Many people consider dung simply as the manure left behind by horses and cows at country shows, or something to be avoided when you visit the cousins’ farm. But dung is actually an important resource for millions of people worldwide. Dung ...

UK needs a national strategy to tackle harms of alcohol, argue experts

2025-01-16

The UK needs an overarching national strategy to tackle alcohol related harms, argue experts in The BMJ today, as deaths from alcohol in England reach their highest level on record. Julia Sinclair at the University of Southampton and colleagues warn that successive government cuts have led to reduced provision and quality of alcohol treatment, and say sustained funding is needed for screening and care, while industry must also shoulder some of the costs. Alcohol is widely available and drunk by around 80% of adults in the UK and is now well established as ...
