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.

Aim To determine whether there is an association between depressive symptoms and parental stress among mothers and fathers during early parenthood in Sweden. Methods In this study, 401 mothers and 396 fathers (393 couples) were included; the Edinburgh Postnatal Depression Scale and the Sense of Coherence Scale were measured 3 months after childbirth, and the Swedish Parenthood Stress Questionnaire and the Sense of Coherence Scale after 18 months. Complete data for multivariable analysis were available for 264 mothers and 252 fathers. Results The mothers estimated greater total depressive symptoms and parental stress than the fathers did. Both the mothers and the fathers had the greatest level of stress in the sub-area ‘Role restriction’. The mothers had the lowest level of stress in the sub-area ‘Social isolation’ and the fathers in the sub-area ‘Incompetence’. The mothers perceived greater levels of stress than the fathers did in all sub-areas except for ‘Social isolation’, where the fathers perceived higher stress. There was an association between the parents’ depressive symptoms and parental stress. The parents’ own depressive symptoms at 3 months and sense of coherence and the partners’ parental stress at 18 months were positively associated with the parental stress at 18 months in univariable and multivariable analyses. Conclusions Understanding the relationship between depressive symptoms and parental stress is important for health professionals so they can offer parents adequate support in early parenthood to optimize the conditions for raising a child. This knowledge should also be communicated to the parents.

Most healthcare professionals rarely experience situations of a request for organ donation being made to the patient’s family and need to have knowledge and understanding of the relatives’ experiences. To describe relatives’ experiences when a family member is confirmed brain dead and becomes a potential organ donor. A literature review and a thematic data analysis were undertaken, guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting process. A total of 18 papers, 15 qualitative and 3 quantitative, published from 2010 to 2019, were included. The electronic search was carried out in January 2019. The overarching theme When life ceases emerged as a description of relatives’ experiences during the donation process, including five subthemes: cognitive dissonance and becoming overwhelmed with emotions, interacting with healthcare professionals, being in a complex decision-making process, the need for proximity and privacy, and feeling hope for the future. The relatives had different needs during the donation process. They were often in shock when the declaration of brain death was presented, and the donation request was made, which affected their ability to assimilate and understand information. They had difficulty understanding the concept of brain death. The healthcare professionals caring for the patient had an impact on how the relatives felt after the donation process. Furthermore, relatives needed follow-up to process their loss. Caring science with an explicit relative perspective during the donor process is limited. The grief process is individual for every relative, as the donation process affects relatives’ processing of their loss. We assert that intensive care unit nurses should be included when essential information is given, as they often work closest to the patient and her or his family. Furthermore, the relatives need to be followed up afterwards, in order to have questions answered and to process the grief, together with healthcare professionals who have insight into the hospital stay and the donation process.

Aim: To investigate whether more secure attachment to the father and the mother is associated with less depressive symptoms among adolescents, and to explore possible sex differences. Method: A population-based sample of adolescents completed a school-based survey assessing demographic data, attachment to father and mother, as well as depressive symptoms. Participation rate was 80% of the eligible population, and 3,988 adolescents (1,937 boys and 2,051 girls) had complete data for the analyses. Results: Paired samples t tests showed that participants rated their attachment to mothers as slightly more secure than their attachment to fathers (t = 15.94, P < 0.001; boys: t = 5.23, P < 0.001; girls: t = 16.16, P < 0.001). In linear regression analyses there was an association between the outcome, number of depressive symptoms, and more secure attachment to the mother for boys (B = −0.532; 95% confidence interval [CI] −0.656, −0.407, P < 0.001) and for girls (B = −0.623; 95% CI −0.730, −0.516, P < 0.001). Analogous results were found for more secure attachment to the father for boys (B = −0.499; 95% CI −0.608, −0.391, P < 0.001) and for girls (B = −0.494; 95% CI −0.586, −0.401, P < 0.001). Conclusions: Understanding the relationship between attachment to both father and mother and depressive symptoms in adolescent boys and girls is essential for further development of strategies for prevention and treatment of depression.

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.
