Summary
Sexual minority (SM) Canadians experience higher preventable mortality rates compared to heterosexuals. Expanding access to affirming healthcare is crucial for reducing these disparities.
Area of Science:
- Public Health
- Epidemiology
- Social Determinants of Health
Background:
- Sexual minority (SM) individuals face health inequities, yet mortality data remain limited.
- Preventable mortality may be influenced by access to social and material resources.
- This study compares preventable mortality between SM and heterosexual adults in Canada.
Purpose of the Study:
- To compare estimates of preventable mortality between sexual minority and heterosexual adults in Canada.
- To investigate the impact of social and material resources on mortality disparities.
Main Methods:
- A population-based retrospective cohort of 442,260 Canadian adults (ages 18-59) was analyzed (2003-2017).
- The Rutstein preventability rating index classified cause-specific mortality.
- Cox proportional hazards models were used for longitudinal analyses.
Main Results:
- SM respondents had higher all-cause mortality (uHR 1.28) and significantly higher mortality from highly-preventable causes (uHR 1.43).
- Elevated mortality hazards were observed for heart disease, accidents, HIV, and suicide among SM individuals.
- Adjustment for social/material resources attenuated the hazard ratio for highly-preventable mortality.
Conclusions:
- Preventable mortality is elevated for sexual minority Canadians compared to heterosexuals.
- Access to social and material resources plays a role in these mortality disparities.
- Expanding access to sexual minority-affirming primary and preventive healthcare is recommended.

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

01:26Factors Affecting the Risk of Infection
12.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:08Prevalence and Incidence
723
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

01:12Relative Risk
284
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
