Governments have enforced measures to limit the spread of COVID-19 with varying degrees of success, which could affect people’s physical activity (PA) and sedentary behavior. This study aimed to examine changes in PA levels, types of PA, and sedentary behavior in the Swedish population before and during the COVID-19 pandemic. Associations between changed PA levels and demographical and behavioral determinants were also investigated. In December 2020, 1035 individuals (18–79 years old) completed a survey about their PA and sedentary behavior before and during the pandemic. Factors influencing their PA were also explored. Fifty-one percent of the sample reported reduced total PA, 18% had no change, and 31% increased their PA. Overall, organized PA decreased the most and sedentary behavior increased. The youngest and oldest age groups reported the greatest reduction in PA, while middle-aged groups reported the most increased PA. Men reported a larger increase in sedentary behavior than women. Mental and physical capability was associated with change in PA. In conclusion, this study indicates that, during the COVID-19 pandemic, the majority of the Swedish population have decreased PA levels with a concurrent increase in sedentary behavior, which may have negative health consequences. Interventions are recommended to address both PA and sedentary behavior, specifically to strengthen people’s ability to perform PA and focusing on the youngest and oldest age groups.

Societal crises and personal challenges are often followed by substantial changes in physical activity. Is there a link between such changes and psychological well-being? Seeking to answer this question, we conducted a correlational study on a representative sample in Sweden during the first year of the COVID-19 pandemic (N = 1035). About 49% of the sample had decreased their physical activity compared to their self-reported activity level prior to the pandemic, whereas 32% had increased it. The results showed a positive and robust association between changes in daily activity level and corresponding changes in psychological well-being. Specifically, individuals who had reduced their physical activity over the last year reported lower life satisfaction than before, and individuals who had increased their physical activity reported higher life satisfaction than before. The amount of complete physical inactivity (sitting) showed a similar pattern as the exercise data, meaning that individuals who reported increasing inactivity per day also reported a greater decline in life satisfaction. Additional analyses showed that the association between daily activity level and life satisfaction was somewhat stronger for men than for women, but there was no difference when comparing individual versus organized activities. The current study was based on a cross-sectional design, measuring self-reported change over time. Recent work from other research teams have used longitudinal data and experience-sampling in different settings, finding similar results. We conclude that there is good reason to recommend physical exercise as a coping strategy in difficult times.

Aim: To investigate the associations between gambling frequency, attention-deficit hyperactivity disorder (ADHD) symptoms, and problem gambling among adolescent boys and girls. One hypothesis was that adolescents with increased ADHD symptoms have a higher frequency of gambling compared to adolescents with fewer ADHD symptoms. Method: A population-based sample of adolescents (aged 15–18 years) completed a questionnaire on demographics, gambling habits, ADHD symptoms, and problematic gambling; 1412 adolescents (from 4440 sampled) with gambling experience were included in the final sample. Results: A zero-inflated negative binomial regression analysis revealed that increased ADHD symptoms, higher gambling frequency, and higher age were associated with lower odds for being non-susceptible to gambling problems. Moreover, gambling frequency interacted with ADHD symptoms in predicting probability of being non-susceptible to gambling problems. However, when analysing those already susceptible to problem gambling, ADHD symptoms did not modify the effect of gambling frequency on the expected magnitude of gambling problems. In susceptible individuals, problem gambling increased with both increased ADHD symptoms and increased gambling frequency, but the level of problems due to gambling frequency did not change depending on the ADHD symptom level. There was an interaction effect between sex and gambling frequency in relation to gambling problems. Conclusions: Adolescents with ADHD symptoms seem to be more sensitive to gambling, in terms of being susceptible to developing gambling problems. However, once susceptible, adolescents with ADHD symptoms are affected by gambling frequency similarly to other susceptible participants.

Although many studies have been conducted on the effects of COVID-19 on individual lives, only a few focus on the changes in mental health and views of public institutions during the pandemic. This study aimed to investigate how mental health, i.e., life satisfaction, worries, and psychological distress, and views on public institutions’ communication and activities have changed among Swedes during the COVID-19 pandemic, and whether this was moderated by age and sex. In April–May 2020 (survey 1) and in January–February 2021 (survey 2), 2554 adults and 1904 newly recruited adults, respectively, anonymously completed online surveys. We found that life satisfaction and psychological distress did not change from survey 1 to survey 2. However, the level of worries increased, and the positive views of the public institutions decreased. Moreover, worries and psychological distress increased more in young adults than older adults. Finally, the change in the views of the public institutions was not related to the change in worries. Our results highlight the COVID-19 long-term impacts on individual mental health and call for the need for future research concerning the consequences for the population, especially among young adults. The results also indicate that the views on activities of public authorities decreased over time, especially among men. Given that loss of this trust can have vastly negative effects, for instance, on the vaccine campaign, it is important to monitor this trend, to increase awareness among Swedish authorities. The results also stress for institutions to provide adequate support both during the COVID-19 pandemic and in a future crisis.

There is already a large body of research on the dramatic negative effects of COVID-19 on peoples’ mental and physical health. Millions of people have died, and the pandemic has negatively influenced the lives of billions of people. Luckily however, the vast majority of people infected with the virus, recovers. The happiness and wellbeing of these people have not been extensively studied. In the current paper, we ask the question: Are people who have recovered from a COVID-19 infection happier than those who have not been infected at all? Building on previous research on hedonic adaptation and counterfactual thinking, we hypothesize, and find, that those who have had an infection appear slightly happier than others. The study relies on two surveys conducted in Sweden during the pandemic in 2020 (n=1029) and 2021 (n=1788).
