More than 1,200 children and adolescents (10-16 years) were monitored over a two year period, during which they were asked, at one-year intervals, to estimate their sense of self, their physical and social abilities, their health, how often they drink alcohol and smoke and how often they act ethically. The study compared children and adolescents active in club sports with those not participating in clubs.
The results of the study were that young people who took part in club sports reported a stronger sense of self, experienced themselves as physically and socially more competent, perceived themselves as having fewer problems with their health, acted somewhat more ethically, and drank less alcohol and smoked less often than their peers who were not active in a sports club.
However, the results show that developments in both groups over time are largely similar and the differences between the two groups are primarily ascribable to the fact that children and adolescents who come from favorable conditions are over-represented in club sports.
“Sports therefore functions partly as an arena for social selection, where children and adolescents with already well-developed characteristics are more likely to start playing a sport, while young people with less well-developed characteristics often give up on sports. This leaves children and adolescents with more positive psychosocial characteristics in organized sports,” says Stefan Wagnsson.
“This shows that the activities pursued in various clubs don’t have much of an impact on the development of young people. Instead, this is determined by factors related to the children’s gender, natural maturity, and ethnic and socioeconomic background. It is very probable that the character-building that takes place in the home and in school, where children and adolescents spend the largest proportion of their time, is what has the greatest impact on young people’s psychological and social growth,” maintains Stefan Wagnsson.
However, the study revealed that club sports do have unexploited potential to be a strong character-building environment. When children and adolescents experience that they are part of a group with leaders who discuss how people should treat each other, where everyone is noticed and respected and receives praise regardless of their level of proficiency, this increases the probability of young people in sports being molded in a favorable direction.

Novels, films, and games that describe wastelands and worlds in ruin tend to feature places of rest – peaceful oases and havens in stark contrast to the surrounding wasteland. What is the function of these places in post-apocalyptic fiction? Karlstad University’s Andreas Nyström investigates further in his doctoral thesis, Places of Rest in Worlds of Ruins: Havens in Post-Apocalyptic Fiction.

The first study to examine prenatal exposure to the phthalate DiNP finds it is associated with a shorter anogenital distance (AGD) in Swedish boys at the age of 21 months. These findings raise concern since animal research has linked DiNP exposure to a shorter AGD, and studies on humans have related shorter AGD to male genital birth defects as well as impaired reproductive function in adult males, and the levels of DiNP metabolites in humans are increasing globally.

Children who had PVC floorings in the bedroom at baseline were more likely to develop asthma during the following 10 years period when compared with children living without such flooring material. Furthermore, there were indications that PVC flooring in the parents’ bedrooms were stronger associated with the new cases of asthma when compared with child’s bedroom. This could be an indication that prenatal exposure is of importance.
