Preventive health care encompasses a range of services, including, but not limited to, primary and dental care, preventive services such as immunizations, and screenings for breast cancer, cervical health, colorectal cancer, and sexually transmitted infections. Use of preventive health care is thought to improve health. Lower use of preventive health care may partly explain poor health among trans populations compared to their cisgender (cis) peers. This entry discusses how access to preventive health care differs between trans and cis populations, summarizes the existing literature on preventive health care among trans populations, and describes key challenges and opportunities for future work.
