Background The COVID-19 pandemic has caused tremendous changes in daily living, which may be related to mental health problems, including psychotic experiences, though research has only begun to assess these associations. Methods We analyzed data from the Healthy Minds Survey (Fall Semester Cohort 2020), which is a non-probability sample of students attending one of 36 universities in the United States, who completed an online survey during the COVID-19 pandemic (September–December 2020). We used multivariable logistic regression to examine the associations between several COVID-19 dimensions (anxiety, discrimination, financial distress, infection, illness of loved one, death of loved one, caregiving) and 12-month psychotic experiences, adjusting for age, gender, race/ethnicity, and international student status. Results Each individual COVID-19 dimension was significantly associated with greater odds of having 12-month psychotic experiences, with the exception of being a caregiver. When accounting for all COVID-19 dimensions simultaneously in the same model, only COVID-19 related anxiety, financial distress, and infection were associated with psychotic experiences. Conclusion COVID-19 dimensions were linked to psychotic experiences among university students, which may also apply to the larger population. This can potentially inform assessment and treatment during the pandemic.

Objective: Immigrants enjoy a health advantage over their US-born counterparts (termed the immigrant paradox), though the extent of this paradox may not extend to all health outcomes. Methods: We analyzed data from the RAND American Life Panel. Using multivariable logistic regression, we examined the associations between immigrant status and a wide range of health outcomes (e.g., cardiovascular diseases, mental health), adjusting for sociodemographic characteristics. Results: Being an immigrant was associated with lower odds of having any health condition, multimorbidity, and number of health conditions. When looking at specific conditions, however, immigrant status was only significantly associated with lower odds of depression, nerve problem causing numbness or pain, and obesity, but not other conditions. Conclusion: The immigrant paradox is evident when examining overall health, and specifically depression, nerve problems, and obesity.

Studies from around the globe have found that urbanicity is associated with greater risk for certain psychiatric disorders, though the association has been less evident in the United States. We analyzed data collected in 2019 from the RAND American Life Panel (n = 2554), which were representative of the general adult population of the United States. Using multivariable logistic regression, we examined the associations between environment of birthplace (large urban, small urban, suburban, rural) and psychiatric disorders, adjusting for sociodemographic characteristics. We found that being born in a large urban area was associated with greater odds of having any psychiatric disorder when compared with being born in a rural area. However, when looking at specific disorders, we found that being born in a large urban area was only significantly associated greater odds of anxiety disorder and post-traumatic stress disorder (PTSD), but was not associated with bipolar disorder, major depressive disorder, attention deficit/hyperactivity disorder, or alcohol/substance use disorder. Being born in a small urban area was marginally associated with anxiety disorder. Future studies should examine why urban birthplace has only been associated with anxiety disorders and PTSD in the United States, and why urbanicity is associated with mood disorders in other parts of the world but not in the United States.
