Background

On March 20, 2020, to stop the spread of the COVID-19, the New York State Governor issued a strict stay at home order for all tasks that were deemed as “non-essential” starting March 22 at 8PM. We would like to determine what change, if any, in physical activity levels (PAL) took place because of the lockdown order in HD patients.

Methods

HD patients were enrolled from 4 clinics in New York City starting in May 2018 and followed for a period of up to 1 year. Patients ≥18 years, on HD ≥3 months, able to walk, and owning a smartphone were enrolled. PAL was defined by steps taken per day measured by with a wrist-based monitoring device (Fitbit Charge 2). Patients still in the study as of March 22, 2020 were included in the study cohort. Average steps per day was calculated for Jan 1-Feb 13, 2020 and the five weeks prior to and after the lockdown went into place. A linear mixed-effect model was used to estimate the average steps per day and 95% confidence intervals. Socioeconomic parameters such as age, race, employment status, and education level were taken at the beginning of the study.

Results

42 patients were included in this analysis. At enrollment patients were 55±11 years old with a dialysis vintage of 4.5±4.4 years, and a BMI of 28.9±8.6 kg/m2. 33% lived alone, 48% were single, 50% unemployed, 69% were African American, and 50% had an education level of some college or higher. Results on average steps per day are presented in Figure 1. Steps per day decreased significantly after the lockdown order with the most significant drop when the COVID-19 pandemic was declared a national emergency

Conclusion

There was a decrease in PAL due to the mandated lockdown. As sedentary behavior is a risk factor for negative outcomes in the HD population, we must implement interventions to promote PAL, such as intradialytic exercise.
