Methods: An electronic survey was disseminated throughout various regions of Texas. In total, 160 individuals were asked questions about their demographic characteristics, time spent on daily physical activities, and daily mental health status before and after COVID-19 was declared a pandemic. Frequency distributions and descriptive statistics were analyzed. Results: Overall, 94 (58{\%}) participants reported having ≥1 medical condition, and 31 (13.1{\%}) had >3 medical conditions. Physical activity levels among participants with ≥1 pre-existing comorbidity drastically---but not significantly---decreased, as evident from a 10{\%} increase in sedentary lifestyles after COVID-19 was declared a pandemic. On the contrary, we observed a 9{\%} increase in the number of individuals without a pre-existing comorbidity who reported 30-60 min of physical activity per week. There was a 2-fold increase in the number of participants reporting more frequent feelings of nervousness, too much worry, trouble relaxing, and the fear of something awful happening after the pandemic. More specifically, individuals with pre-existing medical conditions reported, on average, a 10{\%} higher incidence of feelings of stress, anxiety, and sadness compared to their healthy counterparts after COVID-19 was declared a pandemic. Conclusions: Stressful life conditions and chronic comorbidities are risk factors that can affect mental health and reduce the ability to perform activities of daily life. Therefore, when implementing pandemic protocols, municipalities should consider providing mental health support to their citizens to protect them from this rather inconspicuous adverse effect.
