Summary
Transgender and non-binary people (TNBP) in Spain show higher substance use prevalence than cisgender peers. Public health strategies must address TNBP-specific vulnerabilities and cultural factors in substance use.
Area of Science:
- Public Health
- Epidemiology
- Sociology
Background:
- Substance use disparities are noted between transgender and non-binary people (TNBP) and cisgender individuals.
- Limited comparative studies exist, particularly within European contexts.
- This research addresses the prevalence of substance use among TNBP in Spain.
Purpose of the Study:
- To estimate and compare past-year and past-month prevalence of multiple substance use.
- To compare substance use between transgender women, trans men, non-binary individuals, and their cisgender counterparts in Spain.
Main Methods:
- A cross-sectional study utilized data from 19,948 individuals (aged 15-45), including 1582 TNBP.
- TNBP were primarily recruited via the Transaludes online survey; cis participants and some TNBP were from the EDADES national drug use survey.
- Prevalence of 11 substances was assessed for past-year and past-month use, with adjusted prevalence ratios (aPR) calculated via Poisson regression.
Main Results:
- Cannabis was the most frequently used substance across all groups.
- Poppers were the second most used substance among trans women; non-medical tranquilizers were second for trans men and non-binary people.
- TNBP, especially trans women and non-binary individuals, exhibited higher aPRs for most substances compared to cisgender peers.
Conclusions:
- TNBP demonstrate elevated substance use rates relative to cisgender individuals, with notable differences among women.
- Public health policies require tailored approaches considering cultural and social factors unique to TNB communities.
- Addressing structural vulnerabilities is crucial for effective public health interventions targeting substance use in TNB populations.

Substance Use Disorders Affecting Sleep
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Cross-Sectional Research
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
Longitudinal Studies
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
Longitudinal Research
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Drug Dependence
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...
Drug Abuse and Addiction: Pharmacological Phenomena
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
