- Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.

Undervisning med stöd av förproducerade material : Ett närmande av naturvetenskap i förskolan
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis aims to develop an understanding of the possibilities and challenges pre-produced teaching materials present to teachers and the learning opportunities children are offered in teaching that uses such materials. To do this a study of preschool teachers and children from three preschool departments in Sweden was carried out. The study focuses on the preschool teachers’ descriptions of their planned teaching as well as their realization of their teaching when they use the pre-produced teaching material titled “Science and Technology for All”. The teacher guides to this material, used by the preschool teachers, are also examined. The study is based on a qualitative analysis of interviews, video observations and the teacher guides. The theoretical foundation is based on a pragmatic view from the ideas of John Dewey and the theoretical concepts ultimate and proximate purposes and continuity is used in the analysis.The results of the thesis show that, even though the preschool teachers drew on the same teaching material, they displayed three different teaching practices, each of which created different opportunities to learn natural science for the participating children. The results highlight specific teaching actions that appear to either promote or hinder children's opportunities for learning natural science. The results also show that the teacher guides are vague and ambiguous, thus opening the possibility of different interpretations regarding what should be focused on in the teaching. The study concludes by stressing the importance of clear and unambiguous teacher guides. The results of the study are relevant for teaching in preschool, and other early-years educational settings for example the early school years. The results also have a general validity across a wide range of subject areas.

EXPLORING MOTIVATIONAL MECHANISMS IN EXERCISE BEHAVIOUR : Applying Self-determination theory in a person-centred approach
- 2014
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Involvement in physical activity (PA) and exercise behaviour is multifaceted and depends on bidirectional correlations between multiple factors; one avenue to increase the understanding of sustainable exercise behaviours would be to employ a motivational perspective. In this thesis, this was done by placing the primary focus on Self-determination theory (SDT) as a person-centred approach to study the motivational mechanisms believed to impact exercise behaviour based on the SDT process model. Study 1, conducted in a cross-sectional design, included 1,091 members of a web-based exercise service. Based on sophisticated mediation analysis, the results support the hypothesized associations between latent constructs and exercise behaviour in the related steps of the SDT process model. Moreover, moderating effects were discovered, demonstrating that these associations could differ in different subgroups based on gender and age. The results of Study 1 thereby represent a first indication that exercise intervention design might benefit from slightly different approaches when addressing different demographical groups like gender and age. Study 2 was conducted in a two-wave RCT design to test an SDT-informed intervention on 64 voluntary participants. Components of Motivational interviewing (MI), the Relapse prevention model (RPM) and Cognitive behavioural therapy (CBT) were used as practical application guidelines to deliver the intervention content. Results showed intervention effects on exercise level, exercise intensity and motivation quality as well as mediating effects of the RAI (Relative Autonomy Index; an index of the degree of self-determination), and identified regulation in relation to exercise behaviour. The experimental group also demonstrated significantly lower levels of extrinsic motivation than the control group post-intervention. Besides strong support for applying the basic tenets of SDT in the exercise domain, there are some main findings in this thesis. First of all, self-determined motivation was found to act as a mediating variable in the relationship between psychological need satisfaction and exercise, and these patterns of indirect effects differed across age and gender. This indicates that mechanisms in the SDT process model could vary (qualitatively) depending on subgroup, which carries potential implications for practice. Second, the results of Study 2 also provide evidence that the mediating mechanisms of the process model could be manipulated in an intervention, e.g. by creating need-supportive environments facilitating internalization and subsequent exercise behaviour. Furthermore, both studies demonstrated that identified regulation plays a prominent role in the motivational processes, supporting the significance of promoting internalization in activities like exercise. Finally, this thesis represents prospective value for the utility of employing a polytheoretical approach in exercise intervention design, more specifically regarding the prosperous outlooks in combining SDT with other theories and methods.

- How do parties mobilise cultural expertise in Indigenous rights litigation in Scandinavia? Recently, Sami groups have litigated to claim Indigenous rights to land and natural resources, winning some remarkable victories in the Supreme Courts of Norway and Sweden. In this paper, we draw on socio-legal mobilisation theory to analyse the epistemic strategies of Sami litigants and their adversaries in two recent landmark Supreme Court cases on Indigenous rights to usage of land: the 2020 Girjas case in Sweden and the 2021 Fosen case in Norway. Conceptualising cultural expertise as a strategic framing contest, we analyse how the parties struggled over the epistemic basis of the respective case by legitimating their claims to cultural knowledge, drawing on academic research, and discrediting their opponents' epistemic claims. Our findings suggest that in both cases, Sami claimants successfully established an epistemic basis where their traditional, experiential knowledge combined with independent academic expertise effectively challenged the knowledge claims of their adversaries. Yet, both cases also demonstrate how the linkage between Sami Indigeneity and reindeer husbandry in the national law of both countries excludes non-reindeer herding Sami persons from the Indigenous rights affirmed by the courts.

- Twin studies are an incomparable source of investigation to shed light on genetic and non-genetic components of neurodegenerative diseases, as Alzheimer's disease (AD). Detailed clinicopathologic correlations using twin longitudinal data and post-mortem examinations are mostly missing. We describe clinical and pathologic findings of seven monozygotic (MZ) and dizygotic (DZ) twin pairs. Our findings show good agreement between clinical and pathologic diagnoses in the majority of the twin pairs, with greater neuropathologic concordance in MZ than DZ twins. Greater neuropathologic concordance was found for -amyloid than tau pathology within the pairs. ApoE4 was associated with higher -amyloid and earlier dementia onset, and importantly, higher frequency of other co-occurring brain pathologies, regardless of the zygosity. Dementia onset, dementia duration, difference between twins in age at dementia onset and at death, did not correlate with AD pathology. These clinicopathologic correlations of older identical and fraternal twins support the relevance of genetic factors in AD, but not their sufficiency to determine the pathology, and consequently the disease, even in monozygotic twins. It is the interaction among genetic and non-genetic risks which plays a major role in influencing, or probably determining, the degeneration of those brain circuits associated with pathology and cognitive deficits in AD.

Tidskriftsartikel (refereegranskat)abstract
- We describe and compare the expected performance trajectories of older adults on the Mini-Mental Status Examination (MMSE) across six independent studies from four countries in the context of a collaborative network of longitudinal studies of aging. A coordinated analysis approach is used to compare patterns of change conditional on sample composition differences related to age, sex, and education. Such coordination accelerates evaluation of particular hypotheses. In particular, we focus on the effect of educational attainment on cognitive decline. Regular and Tobit mixed models were fit to MMSE scores from each study separately. The effects of age, sex, and education were examined based on more than one centering point. Findings were relatively consistent across studies. On average, MMSE scores were lower for older individuals and declined over time. Education predicted MMSE score, but, with two exceptions, was not associated with decline in MMSE over time. A straightforward association between educational attainment and rate of cognitive decline was not supported. Thoughtful consideration is needed when synthesizing evidence across studies, as methodologies adopted and sample characteristics, such as educational attainment, invariably differ.
