Article Synopsis
  • Physical activity (PA) decreased during the COVID-19 pandemic and did not fully recover, with women showing a slight increase in 2022, while men did not.
  • Sedentary behavior (SB) increased from 2019-2020 but later returned to near pre-pandemic levels for most age groups, except for younger and older individuals who experienced lasting changes.
  • Different demographic and occupational factors influenced PA and SB, indicating a need for tailored interventions to help specific groups regain their pre-pandemic activity levels.

Background: It has been reported that physical activity levels decreased during the COVID-19 pandemic. Previous studies often relied on self-reported physical activity, which has low accuracy. Studies based on objectively measured physical activity have had short data collection periods, thereby not allowing the consideration of pre-pandemic levels of physical activity or the influence over the different waves of the pandemic.

Physical activity (PA) and sedentary behavior (SB) affect people's physical and mental health. The aim was to examine changes in PA and SB in a Swedish population: at three time points: 2019, 2020, and 2022, i.e.

Article Synopsis
  • Solvation of [(CNT)Ln(η-COT)] complexes with THF leads to the formation of neutral and ionic species depending on the lanthanide (Ln) used, with noticeable differences in their solid-state properties.
  • These complexes can serve as switchable luminophores and single-molecule magnets due to the changes in their ligand environment during solvation.
  • The desolvation process can be effectively controlled using a dynamic vacuum or temperature gradients, with Raman spectroscopy showing the reversibility of these transitions, which can be further induced by a Nd:YAG laser for self-sufficient mechanisms in specific compounds.

This paper reports on four exploratory online studies of how wellbeing and welfare are valued and perceived from a subjective, individual perspective. Study 1 ( = 707) compares individuals' subjective ratings and correlations of the importance of the three wellbeing dimensions happiness, meaning in life, and a psychologically rich life, as well as their welfare. Study 2 ( = 679) factor-analyses the same four (five-item) wellbeing and subjective welfare constructs.
