Abstract
A growing number of men who have sex with men (MSM) utilise Grindr for seeking relationships and immediate/casual sexual encounters. Grindr and other mobile applications can be a valuable source of information on sociological predictors of health. One topic that is under reported is the use of Grindr by MSM with obesity. We described differences in Grindr use between MSM with and without obesity, and to use Grindr information to reveal trends which may serve as potential predictors of health.
Data was collected from 3744 Grindr users (mean age [s.d.], 32.3 years [9.1]) from the largest 50 metropolitan centres in the USA between February and May 2018. Users were divided into two cohorts based on BMI: (1) MSM with obesity (BMI > 30), n = 253; and (2) MSM without obesity, n = 3491. Profile characteristics were compared.
When evaluating potential predictors for obesity, we found that black/African-American and older MSM were significantly more likely to have obesity. Further, we found that obesity among MSM was significantly inversely associated with the population percent lesbian, gay, bisexual, and transgender (LGBT) within a city. Additionally, we found that MSM with obesity were significantly more likely to indicate interest in immediate sexual encounters.
These results highlight important trends that may serve as predictors of health in urban settings. Furthermore, our results suggest that MSM with obesity may be more likely to engage in risky sexual behaviours. These findings may be useful in informing providers and healthcare officials on when and how to provide outreach to this unique population.
Keywords: BMI, Grindr, Hookup app, LGBT health, men’s health, MSM, obesity, race/ethnicity, sexual health.
