Racial Differences in Generalized Anxiety Disorder During the COVID-19 Pandemic among Brazilian University Students: a National Survey

Abstract

There is evidence that during the COVID-19 pandemic, there was an increase in anxiety and depression rates among college students. However, little is known about how generalized anxiety disorder (GAD) developed among individuals of different race/skin color. This study aimed to determine whether there are racial differences in GAD in Brazilian university students during the COVID-19 pandemic. This is a nationwide cross-sectional study, carried out through the application of online questionnaires to university students from 94 Brazilian universities. Self-reported data on age, sex, economic class, race/skin color, anthropometric data, and adherence to social distancing measures were collected. To determine the GAD, the Generalized Anxiety Disorder 7-item scale was applied. A total of 5879 participants were included, with a mean age of 24.1 ± 6.4 years, and the majority were female (n = 4324, 73.5%), most self-declared to be whites (n = 2945, 50.1%), followed by browns (n = 2185, 37.2%) and blacks (n = 749, 12.7%). The prevalence of GAD among black Brazilian university students (47.3% [95% CI 43.7, 50.8]) was significantly higher than that of browns (38.6% [95% CI 36.6, 40.7]) and whites (44.1% [95% CI 42.3, 45.9]), even after multivariable adjustment by other sociodemographic factors. The findings of the present study suggest a possible racial difference in GAD among Brazilian university students, in which those who declared their race/skin color as black showed a greater risk for GAD than those who declared themselves as white or brown.
