Little is known about cardiovascular health disparities for lesbian, gay, or bisexual (LGB) persons and whether these disparities are mediated by mental health disorders due to sexual minority stress. We hypothesize LGB identity is associated with an increased risk of cardiovascular disease (CVD) and that major depressive disorder (MDD) and generalized anxiety disorders (GAD) may mediate this association.
The National Epidemiologic Survey on Alcohol and Related Conditions is a longitudinal, nationally-representative study of non-institutionalized U.S. adults. We cross-sectionally analyzed the second wave data (2004-2005) comparing 577 self-identified LGB persons to 33,598 heterosexuals. Multiple logistic regression modeling and mediation analysis (the product of coefficients approach) were performed.
LGB persons had significantly higher CVD prevalence [adjusted odds ratio (AOR): 1.5, 95% CI: 1.2-1.9], and were more likely to be diagnosed with MDD (AOR: 1.9, 1.8-2.1), GAD (AOR: 2.2, 1.9-2.4), or co-occurring MDD and GAD (AOR: 2.2, 2.0-2.5). MDD, GAD, and co-occurrence of MDD and GAD significantly mediated 14.3%, 22.2%, and 33.3% of the association of LGB status with increased CVD prevalence, respectively.
Our findings identified a 50% increased CVD prevalence among LGB persons and this increased risk was mediated in part by MDD and GAD, both being more prevalent in sexual minority adults.
This research output has an Altmetric Attention Score of 5. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 March 2025.
All research outputs
#7,924,322
of 28,041,331 outputs
Outputs from Preventive Medicine
#2,672
of 5,216 outputs
Outputs of similar age
#133,798
of 459,696 outputs
Outputs of similar age from Preventive Medicine
#52
of 80 outputs
Altmetric has tracked 28,041,331 research outputs across all sources so far. This one has received more attention than most of these and is in the 71st percentile.
So far Altmetric has tracked 5,216 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 22.1. This one is in the 48th percentile – i.e., 48% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 459,696 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
We're also able to compare this research output to 80 others from the same source and published within six weeks on either side of this one. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
