Transgender and gender diverse (TGD) adults are more likely to have obesity compared to cisgender peers. Based on surveys, the TGD population experiences disparities in healthy lifestyle behaviors (e.g., physical activity, screen time) compared to reference groups. They also face significant socioeconomic and healthcare barriers to accessing affirming care and gender minority stress, potentially contributing to increased weight. Gender-affirming hormone therapy is associated with changes in body composition and increased weight, which may impact cardiometabolic risk trajectory. Obesity can also be a barrier to gender-affirming surgeries, and affirming weight management services tailored to TGD patients are an important gap in healthcare to address. This Perspective briefly reviews current literature on the unique barriers experienced by TGD people and their identified needs regarding weight management interventions. It also suggests areas for future research to best fill this gap in healthcare and research while supporting the provision of lifesaving gender-affirming care.

Health considerations for transgender women and remaining unknowns: a narrative review
2019
Transgender (trans) women (TW) were assigned male at birth but have a female gender identity or gender expression. The literature on management and health outcomes of TW has grown recently with more publication of research. This has coincided with increasing awareness of gender diversity as communities around the world identify and address health disparities among trans people. In this narrative review, we aim to comprehensively summarize health considerations for TW and identify TW-related research areas that will provide answers to remaining unknowns surrounding TW’s health. We cover up-to-date information on: (1) feminizing gender-affirming hormone therapy (GAHT); (2) benefits associated with GAHT, particularly quality of life, mental health, breast development and bone health; (3) potential risks associated with GAHT, including cardiovascular disease and infertility; and (4) other health considerations like HIV/AIDS, breast cancer, other tumours, voice therapy, dermatology, the brain and cognition, and aging. Although equally deserving of mention, feminizing gender-affirming surgery, paediatric and adolescent populations, and gender nonbinary individuals are beyond the scope of this review. While much of the data we discuss come from Europe, the creation of a United States transgender cohort has already contributed important retrospective data that are also summarized here. Much remains to be determined regarding health considerations for TW. Patients and providers will benefit from larger and longer prospective studies involving TW, particularly regarding the effects of aging, race and ethnicity, type of hormonal treatment (e.g. different oestrogens, anti-androgens) and routes of administration (e.g. oral, parenteral, transdermal) on all the topics we address.

As the transgender and gender diverse (TGD) population ages, more transfeminine and transmasculine individuals present to clinic to initiate or continue their gender-affirming care at older ages. Currently available guidelines on gender-affirming care are excellent resources for the provision of gender-affirming hormone therapy (GAHT), primary care, surgery, and mental health care but are limited in their scope as to whether recommendations require tailoring to older TGD adults. Data that inform guideline-recommended management considerations, while informative and increasingly evidence-based, mainly come from studies of younger TGD populations. Whether results from these studies, and therefore recommendations, can or should be extrapolated to aging TGD adults remains to be determined. In this perspective review, we acknowledge the lack of data in older TGD adults and discuss considerations for evaluating cardiovascular disease, hormone-sensitive cancers, bone health and cognitive health, gender-affirming surgery, and mental health in the older TGD population on GAHT.

Objective Although aging is associated with reduced hunger and energy intake (EI), obesity is increasing in older adults. This study aimed to identify appetite regulation differences between older adults with obesity and older adults with normal weight (NW). Methods This cross‐sectional study recruited older adults with obesity (BMI 30–40 kg/m2) and NW (BMI < 25 kg/m2) aged 65–85 years. Fasting appetite‐related behavioral questionnaires were collected. Ghrelin, polypeptide YY [PYY], glucagon‐like peptide‐1 [GLP‐1], glucose, insulin, and triglycerides were measured fasting and every 30 min for 3 h following a test breakfast, and the incremental area under the curve (iAUC) was calculated. Results 13 older adults with obesity (aged 70.8 ± 4.0 years, 54% female, BMI 33.1 ± 3.6 kg/m2) and 14 with NW (aged 70.8 ± 5.3 years, 71% female, BMI 22.5 ± 2.1 kg/m2) were analyzed. Compared to older adults with NW, older adults with obesity had higher disinhibition and perceived hunger (p < 0.001 and p < 0.05, respectively), lower confidence in preventing overeating (p < 0.05), higher fasting GLP‐1 and insulin (both p < 0.05), and higher PYY and insulin iAUCs (p < 0.01 and p < 0.05, respectively). Conclusion Despite similar meal‐related appetite and EI, older adults with obesity had higher fasting disinhibition, perceived hunger, GLP‐1 and insulin, higher PYY and insulin iAUCs, and lower confidence in preventing overeating than those with NW. These differences between older adults with obesity and NW have implications for tailored obesity treatments in older adults. Aging can be associated with anorexia and weight loss, but obesity is also increasing among older adults. Compared to older adults with normal weight (n = 14, red line), older adults with obesity (n = 13, blue line) had (1) altered eating‐related behaviors, including higher disinhibition and perceived hunger and lower confidence in preventing overeating, (2) differences in appetite‐related hormones, including higher fasting glucagon‐like peptide‐1 and polypeptide YY meal response, and (3) greater insulin resistance. These differences in appetite‐related behaviors and peptides have implications for tailored obesity treatments in older adults.

Abstract
Transgender and gender diverse (TGD) individuals face significant barriers to accessing health care. Recent introductions of regulatory policies at state and federal levels raise concerns over the politicization of gender-affirming health care, the risks of further restricting access to quality care, and the potential criminalization of healthcare professionals who care for TGD patients. The Endocrine Society and the Pediatric Endocrine Society have published several news articles and comments in the last couple of years supporting safe and effective gender-affirming interventions as outlined in the 2017 Endocrine Society’s Clinical Practice Guidelines. The Endocrine Society Position Statement on Transgender Health also acknowledges the rapid expansion in understanding the biological underpinning of gender identity and the need for increased funding to help close gaps in knowledge about the optimal care of TGD individuals. This Policy Perspective affirms these principles in the context of pending and future legislation attempting to discriminate against TGD patients while also stressing the need for science and health care experts to inform health policies.

Approach to the Patient: Hormonal Therapy in Transgender Adults With Complex Medical Histories
2024
Abstract
While endocrinologists continue to initiate gender-affirming hormone therapy (GAHT) in healthy transgender and gender diverse (TGD) patients, they may also encounter more TGD patients in their clinics with complex medical histories that influence the patient-provider shared decision-making process for initiating or continuing GAHT. The purpose of this Approach to the Patient article is to describe management considerations in 2 adults with thromboembolic disease and 2 adults with low bone mineral density in the setting of feminizing and masculinizing GAHT.

Despite the growing number of adult transgender and gender diverse (TGD) patients seeking health services, there are many unknowns regarding how routine screening recommendations should be applied to TGD persons receiving gender-affirming hormone therapy (GAHT). Patients taking GAHT may have disease risks that differ from what is expected based on their sex assigned at birth or affirmed gender identity. We discuss two patient cases, one transgender man and one transgender woman who present for routine medical care, to review several conditions that may be impacted by the hormones utilized in masculinizing and feminizing GAHT and for which screening recommendations are available for TGD adults: cardiovascular risk factors, osteoporosis, breast cancer, cervical cancer, and prostate cancer. We reviewed the TGD-specific screening recommendations from several major medical organizations and programs and found them to be largely based upon expert opinion due to a lack of evidence. The goal of this narrative review is to assist healthcare professionals in counseling and screening their TGD patients when and where appropriate. Not all TGD adults have the ability or need to receive routine medical care from a specialized TGD health clinic; therefore, it is essential for all healthcare professionals involved in routine and gender-affirming care to have knowledge about these conditions and screenings.

Abstract
Body mass index (BMI) requirements for gender-affirming surgeries (GAS) present an obstacle to gender transition for many transgender and gender diverse (TGD) people. Furthermore, TGD people have unique barriers and preferences in managing their weight that must be considered. TGD patients frequently present to their endocrinologists for individualized, gender-affirming support to meet BMI cutoffs for GAS. This Approach to the Patient article combines expertise from several disciplines, including gender-affirming hormone management, weight management, mental health, gynecology, and plastic surgery. Multidisciplinary management considerations are offered for clinicians to assist TGD patients with obesity navigate BMI requirements to access GAS.
