- Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified.

- OBJECTIVES: Assess the risk of ischaemic events associated with psychosocial stress in patients with stable coronary heart disease (CHD).METHODS: Psychosocial stress was assessed by a questionnaire in 14 577 patients (median age 65.0, IQR 59, 71; 81.6% males) with stable CHD on optimal secondary preventive therapy in the prospective randomized STABILITY clinical trial. Adjusted Cox regression models were used to assess associations between individual stressors, baseline cardiovascular risk factors and outcomes.RESULTS: After 3.7 years of follow-up, depressive symptoms, loss of interest and financial stress were associated with increased risk (hazard ratio, 95% confidence interval) of CV death (1.21, 1.09-1.34; 1.15, 1.05-1.27; and 1.19, 1.08-1.30, respectively) and the primary composite end-point of CV death, nonfatal MI or nonfatal stroke (1.21, 1.13-1.30; 1.19, 1.11-1.27; and 1.17, 1.10-1.24, respectively). Living alone was related to higher risk of CV death (1.68, 1.38-2.05) and the primary composite end-point (1.28, 1.11-1.48), whereas being married as compared with being widowed, was associated with lower risk of CV death (0.64, 0.49-0.82) and the primary composite end-point (0.81, 0.67-0.97).CONCLUSIONS: Psychosocial stress, such as depressive symptoms, loss of interest, living alone and financial stress, were associated with increased CV mortality in patients with stable CHD despite optimal medical secondary prevention treatment. Secondary prevention of CHD should therefore focus also on psychosocial issues both in clinical management and in future clinical trials.

Tidskriftsartikel (refereegranskat)abstract
- Background: Physical education (PE) teachers in practically all countries are expected to help their students develop movement capability. To achieve this objective, teachers need certain knowledge and competencies. The question of how PE teachers should develop their capacities to achieve this task has received only limited research attention.Aim: The broad objective of this paper is to contribute to the literature on how PE teachers can develop knowledge and competencies in the area of movement capability related to students' learning. The specific aim is to identify aspects of the design of instruction in physical education that enhance teachers' actor-oriented transfer of movement pedagogy knowledge, during a collaborative professional development intervention.Method: The study is an analysis of three conducted learning studies in PE at upper secondary schools in Sweden. The studies involved seven PE teachers from two different schools. Our empirical material consists of (a) notes from team meetings (n = 14), (b) lesson plans (n = 9), (c) video-recorded and transcribed lessons (n = 9), and (d) results of students' learning outcomes (n = 9).Findings: PE teachers' analysis of their own teaching sequences in teams supported their actor-oriented transfer of movement pedagogy knowledge, which developed their abilities to further elaborate their instruction in new teaching situations. Moreover, teachers gained insights into how to further develop the quality of instructional design as expansions of earlier experiences. Lastly, a relationship between PE teachers' actor-oriented transfer and students' increased learning of movements was found.Conclusion: Our conclusion is that collaborative professional development for PE teachers, which supports actor-oriented transfer, should be offered to enhance teachers' movement pedagogy knowledge.

Constructing Consumer Knowledge in Market Research : An Ethnography of Epistemics
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Market research pervades society. It is an endeavour that connects marketing practice with methods similar to social science. Further, market research results appear as knowledge produced to inform recipients towards making productive business decisions and as a commodity sold to commissioning clients. I suggest that such commissioned knowledge production must be approached taking into account both the making and the marketing of such material. The position of market research between concerns to know through research and to market goods and services, including its own, has been approached differently in academic scholarship. Examples range from criticism against surveillance and manipulation, to calls to defining the benefits of market research techniques for organising markets and societies. Researchers have tried to explain this knowledge making for market research as a construction of objects of knowledge or as a performative phenomenon. This thesis takes an ethnographic and cultural approach to market research work and the researchers that undertake it. Based on fieldwork with Swedish firm Norna (pseudonym) and handbooks from industry organisation ESOMAR, the thesis inquires into the epistemic practices and epistemology of market research, how market researchers consider their work influenced by the relations that they maintain and how ideas and practices in market research inform understanding of commissioned knowledge production.The thesis consists of four articles dealing with the ideas, actors and processes that engage market researchers. The first article assesses market research industry handbooks and discusses the contribution of performativity approaches in light of this local epistemology. The second article studies how market researchers shape their respondents as part of producing consumer knowledge. The third article assesses how the work processes of market research knowledge production rely on the production and distribution of ignorance to successfully keep respondents and clients at the right certainty interval. The fourth article examines client relations and how market researchers produce materials to satisfy clients as well as shape clients’ preferences and understanding.The findings of the thesis point to how market research features its own local epistemics and reflexivity on the part of researchers, but also the tensions and ambiguities involved. Market researchers handle commercial pressures and epistemic quandaries in parallel and overlapping relational practice through the production and deployment of both knowledge and ignorance. Dealing with clients and respondents transcends the distinction between the commercial and the informative. The text informs a further understanding of market research, its techniques by means of engaging with how its researchers view this activity. Further it challenges the social study of knowledge production by showing how in this case it includes concerns that are not simplistically commercial or epistemic.

- OBJECTIVE: To investigate the sex- and age-specific incidence of healthcare-register-recorded anorexia nervosa (AN) and other eating disorders (OED) in a complete birth cohort, and assess whether incidence varies by diagnostic period and (sub-) birth cohort.METHOD: We used the actuarial method and Poisson models to examine the incidence of AN and OED from 1987 to 2009 (when individuals were 8-30 years old) for a cohort of 2.3 million individuals (48.7% female) born from 1979 to 2001 in Sweden, identified using Swedish registers.RESULTS: For both sexes, incidences of AN and OED increased considerably for diagnostic periods after 2000, but differed little by birth cohort. In 2009, AN incidence in the peak age category was 205.9 cases/100,000 persons (95% CI: 178.2, 233.5) for females (14-15 years), versus 12.8 cases/100,000 (95% CI: 5.6, 20.1) for males (12-13 years). OED incidence in the peak age category was 372.1 cases/100,000 (95% CI: 336.4, 407.9) for females (16-17 years), versus 22.2 cases/100,000 (95% CI: 13.3, 31.1) for males (14-15 years).DISCUSSION: Our finding of an increase in healthcare-register-recorded eating disorders for diagnostic periods after 2000 likely reflects improved detection and expanded register coverage in Sweden. The peak of eating disorder incidence in adolescence, which began unexpectedly early for AN in males, suggests the importance of vigilance for signs of AN in young boys and early primary prevention efforts. Waiting until later could miss critical windows for intervention that could prevent disorders from taking root.

Theory-of-mind in individuals with Alström syndrome is related to executive functions, and verbal ability
- 2015
-
Ingår i: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 6

Tidskriftsartikel (refereegranskat)abstract
- Objective: This study focuses on cognitive prerequisites for the development of theory-of-mind (ToM), the ability to impute mental states to self and others in young adults with Alström syndrome (AS). AS is a rare and quite recently described recessively inherited ciliopathic disorder which causes progressive sensorineural hearing loss and juvenile blindness, as well as many other organ dysfunctions. Two cognitive abilities were considered; Phonological working memory (WM) and executive functions (EF), both of importance in speech development. Methods: Ten individuals (18–37 years) diagnosed with AS, and 20 individuals with no known impairment matched for age, gender, and educational level participated. Sensory functions were measured. Information about motor functions and communicative skills was obtained from responses to a questionnaire. ToM was assessed using Happés strange stories, verbal ability by a vocabulary test, phonological WM by means of an auditory presented non-word serial recall task and EF by tests of updating and inhibition. Results: The AS group performed at a significantly lower level than the control group in both the ToM task and the EF tasks. A significant correlation was observed between recall of non-words and EF in the AS group. Updating, but not inhibition, correlated significantly with verbal ability, whereas both updating and inhibition were significantly related to the ability to initiate and sustain communication. Poorer performance in the ToM and EF tasks were related to language perseverance and motor mannerisms. Conclusion: The AS group displayed a delayed ToM as well as reduced phonological WM, EF, and verbal ability. A significant association between ToM and EF, suggests a compensatory role of EF. This association may reflect the importance of EF to perceive and process input from the social environment when the social interaction is challenged by dual sensory loss. We argue that limitations in EF capacity in individuals with AS, to some extent, may be related to early blindness and progressive hearing loss, but maybe also to gene specific abnormalities.

Tidskriftsartikel (refereegranskat)abstract
- New fields such as bioengineering are exploring the role of the physical sciences in traditional biological approaches to problems, with exciting results in device innovation, medicine, and research biology. The integration of mathematics, biomechanics, and material sciences into the undergraduate biology curriculum will better prepare students for these opportunities and enhance cooperation among faculty and students at the university level. We propose the study of sports science as the basis for introduction of this interdisciplinary program. This novel integrated approach will require a virtual human performance laboratory dual-hosted in Sweden and the United States. We have designed a course model that involves cooperative learning between students at Göteborg University and Stanford University, utilizes new technologies, encourages development of original research and will rely on frequent self-assessment and reflective learning. We will compare outcomes between this course and a more traditional didactic format as well as assess the effectiveness of multiple web-hosted virtual environments. We anticipate the grant will result in a network of original faculty and student research in exercise science and pedagogy as well as provide the opportunity for implementation of the model in more advance training levels and K-12 programs.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- We are designing a course to be taught simultaneously at Göteborg University and Stanford University. We will present two approaches to creating a virtual environment in sport science experiments that are central to the course. The first virtual environment allows students at any location to utilize Marratech web-hosting software to conduct real-time experiments in venues as sophisticated as Lundberg Laboratories in Göteborg and the Stanford Human Performance Laboratory. We have conducted two trials to validate the feasibility of this design, which accommodates simple technologies such as a laptop and consumer devices at the participant site. The second virtual environment is a computer-generated biomechanics laboratory that will allow students to conduct experiments of their own design. Both Göteborg and Stanford will collect motion capture and force plate data on Olympic-caliber and professional athletes. Students will manipulate this data to conduct novel biomechanical investigations under the direction of a set of learning models under development.
