The Impact of the COVID-19 Pandemic on the Lifestyles and Levels of Anxiety and Depression of Patients with Schizophrenia: A Retrospective Observational Study

The movement restrictions put in place as a result of the COVID-19 pandemic required modification of the population's usual routines, including those of the most vulnerable groups such as patients with schizophrenia. This was a retrospective observational study. We used an online survey to collect information on patient adherence to the Mediterranean diet (Mediterranean Diet Adherence Screener questionnaire), physical exercise (International Physical Activity Questionnaire Short Form), and tobacco consumption and levels of anxiety and depression (Hospital Anxiety and Depression Scale) before and during the movement restrictions. A total of 102 people with schizophrenia participated in this study. During the COVID-19 pandemic lockdown the participants significantly increased the number of minutes spent sitting per day (z = -6.73; p < 0.001), decreased the time they spent walking (z = -6.32; p < 0.001), and increased their tobacco consumption (X² = 156.90; p < 0.001). These results were also accompanied by a significant increase in their reported levels of anxiety (z = -7.45; p < 0.001) and depression (z = -7.03, p < 0.001). No significant differences in patient diets during the pandemic compared to before the movement restrictions were reported. These results suggest the need to implement specific programs to improve lifestyle and reduce anxiety and depression during possible future pandemic situations.
