Investigating Physical Activity Habits and Sleep Disorders in the Nursing Staff of Greece During the COVID-19 Pandemic: A Multicenter Cross-Sectional Correlational Study

Introduction: The social isolation (lockdown) used worldwide as a measure to effectively prevent the infection of COVID-19 has been shown to be responsible for the high prevalence of depression, anxiety, insomnia, and post-traumatic stress symptoms. The aim of this study was to investigate the physical activity habits and sleep disorders in the nursing staff.

Methodology: This is a multicenter cross-sectional correlational study. The study population consisted of nurses and nursing assistants. Data were collected using the Greek version of the Pittsburgh Sleep Quality Index, the Fear of the COVID-19, and the Physical exercise questionnaire of the American College of Sports Medicine. Statistical analysis of data was done with IBM SPSS v. 22.0.

Results: A total of 1710 nursing personnel aged 42.3 ± 9.1 years were included. At the beginning of the COVID-19 pandemic, 190 (11.1%) participants were physically active, and 2 years after the beginning of the COVID-19 pandemic, active were 130 (7.6%) participants. Both at the beginning and two years after the beginning of the pandemic, the sleep dimensions that scored higher were subjective sleep quality (1.98 ± 0.2 vs. 1.98 ± 0.3), sleep onset latency (1.89 ± 1.5 vs. 1.64 ± 1.6), and sleep duration (1.55 ± 0.9 vs. 1.65 ± 0.8). The total sleep score was 8.64 ± 3.1 at the beginning of the pandemic and 8.11 ± 3.7 two years after the beginning of the pandemic.

Conclusions: Nurses and nurses' assistants had less physical activity habits, slept less, and had more sleep disorders 2 years after the beginning of the pandemic in relation to the beginning of the pandemic.
