The study aimed to examine the impact of state stay-at-home mandates on weight of US adults during COVID-19. It found that US adults gained weight, with individuals with obesity experiencing greater weight gain. Factors such as longer stay-at-home mandates, decreased physical activity, depressive symptoms, and increased time preparing food were associated with greater weight gain.
Objective The purpose of this study was to prospectively examine the effect of state stay-at-home mandates on weight of US adults by BMI over 3 months during COVID-19. Methods US adults completed an online questionnaire containing demographics, weight, physical activity, sedentary time, fruit/vegetable intake, depressive symptoms, stress, and sleep at baseline (May 2020) and after 3 months (August 2020). Results Participants gained 0.6 kg (76.7-77.3 kg, p = 0.002). A total of 26% of those with obesity gained > 2 kg compared with 14.8% of those with normal weight (p < 0.001). A total of 53.3% of individuals with obesity maintained weight within 2 kg compared with 72.5% of those with normal weight (p < 0.001). Greater weight gain was related to longer stay-at-home mandates (beta = 0.078, p = 0.010), lower baseline minutes of physical activity per day (beta = -0.107, p = 0.004), greater declines in minutes of physical activity per day (beta = -0.076, p = 0.026), depressive symptoms (beta = 0.098, p = 0.034), and greater increases in time preparing food (beta = 0.075, p = 0.031). Conclusions US adults gained weight, and stay-at-home mandates were associated with atypical weight gain and greater reported weight gain in individuals with obesity over 3 months.
