Fatigue and physical activity levels in poles living in Poland and the United Kingdom in the further year of the COVID-19 pandemic: a pilot study

OBJECTIVES: The aim of this study was to conduct a preliminary assessment of the prevalence of fatigue and level of physical activity, as well as the relationship between fatigue and physical activity among Poles living in Poland and the United Kingdom (UK) in the further year in the COVID-19 pandemic. METHODS: A web-based online survey was conducted among Poles living permanently in Poland and the UK in January 2023. Responses were obtained from 200 respondents aged 18–69 years. The level of fatigue was assessed by the Modified Fatigue Impact Scale (MFIS). The level of physical activity was measured by the International Physical Activity Questionnaire (IPAQ). RESULTS: The median for the total fatigue score was equal to 17 points out of a possible 105. 13.5% of the subjects had a low level of physical activity, the average MET for high-intensity activity was 1294.55 METs, for moderate activity 714.44 METs, and for walking 631 METs. As age and number of COVID-19 cases increased, scores on the MFIS questionnaire scale also increased. With an increase in the number of COVID-19 cases, high-intensity MET scores decreased. CONCLUSIONS: The level of fatigue, in contrast to the level of physical activity, was low in the study population. There were few statistically significant differences in fatigue between people living in Poland and the UK. Further experimental studies on the physiological mechanism of differences in fatigue and physical activity are needed.
