Background and Clinical Significance: Sarcopenia, characterized by muscle loss and fat infiltration, poses a significant health burden for aging populations. Quantitative Color 2D and 3D radiodensitometry provides a powerful tool to monitor muscle quality and quantity through CT imaging. This study assessed the impact of a ten-year-long home-bed gym exercise intervention on muscle quality in an elderly subject using CT-derived radiodensitometric analysis. The study involved two comparative analyses: Study A, which compared knee-to-ankle CT scans of the subject between 2013 and 2023; and Study B, which compared the subject’s 2023 thigh CT scan with a cohort of 2500 elderly Icelandic individuals from the AGES-Reykjavik study. Case Presentation: A 70-year-old male began a home-based Full-Body In-Bed Gym exercise program in 2013. Quantitative muscle volume and radiodensity measurements were performed using CT at baseline and after ten years. Results: Study A shows significant improvements in muscle volume observed in the knee-to-ankle region, while a slower decline in radiodensity was noted, indicating substantial preservation of muscle quality despite the expected decay of ten-year aging. For instance, muscle volume increased by 15% in the left Soleus muscle and by 6% in the right Soleus muscle, while the average radiodensity decreased by 12–17 HU. The subject’s thigh muscle quality at 80-years-old is above the AGES-Reykjavik’s cohort average, with reduced fat infiltration. Conclusions: Long-term home Full-Body In-Bed Gym, a low-impact exercise, can mitigate aging sarcopenia, as evidenced by improved tissue radiodensity and muscle mass substantial preservation. This suggests potential applications in personalized healthcare strategies to enhance muscle preservation among aging populations. Full article

This article focuses on the figures concerning experiences of and beliefs in possible contacts with the dead amongst Icelandic people that have come to light from three national surveys that were undertaken in 1974, 2006–2007, and 2023, focusing in particular on the most recent figures. It starts by reviewing the earliest evidence of such beliefs in Iceland (expressed in both Old Icelandic literature and Icelandic folk legends), which evidently laid down the foundations for modern-day beliefs. After listing the main findings of the surveys and noting the changes in belief that appear to have taken place over the last 50 years, the article offers some brief conclusions relating to what seems to have caused not only some obvious gender and age differences in belief and experience, but also differences in figures between urban and rural areas.

Food is one of the main drivers of global greenhouse gas (GHG) emissions. Therefore, it is crucial to investigate the environmental impact of food choices. A National Dietary Survey (NDS) is executed every ten years in Iceland. However, the dietary carbon footprint (DCF) based on the results from the NDS has not been estimated for Iceland before. Thus, the objective was to assess the DCF of dietary habits of adults living in Iceland. A carbon footprint modelling tool was implemented using data from three independent LCA databases from Denmark, the US, and France. The DCF was calculated using results from the latest NDS, including data from 2019 to 2021. This was a random study sample of 18–80 year old inhabitants living in Iceland with 822 participants, including 428 (52%) females and 394 (48%) males. The participation rate in the NDS was 51%. The average total DCF from the three databases was 5.7 kg CO₂-eq/day. The highest emissions originated from the consumption of meat and meat products (49%) (median intake 850 g/week) and dairy products (15%) (median intake 250 g/day), while emissions from the consumption of seafood (median intake 130 g/week) had a broader range (3–10%). Beverages also contributed to a significant proportion (12%), plant sources contributed 3%, and other food groups combined contributed 13% of the DCF in all three databases. The DCF for the participants following the Planetary Health Diet, the Nordic Nutrition Recommendations, and the Danish food-based dietary guidelines for intake levels of meat and dairy products was an average of 2.6 kg CO₂-eq/day. The main driver of GHG emissions from food consumption, identified by the three databases, was meat and dairy products, contributing to an average of 64% of the total DCF. When estimating the DCF for participants following recommendations for meat and dairy consumption, a similar pattern emerged, where the DCF decreased from 5.9–2.6 kg CO₂-eq. These consistent results suggest that uncertainties in estimating the DCF from different food groups using the three databases are not critical in identifying key drivers of GHG emissions.

The monastic archives of Iceland have rarely been made the subject of specific studies. This article is intended to survey the history of one such archive, belonging to the Benedictine Abbey of Þingeyrar in Northern Iceland, which was founded 1133 and dissolved 1551. Through its extraordinarily rich literary production this monastery left an indelible mark on the Northern-European cultural heritage. After the Reformation Þingeyrar Cloister remained a state-owned and ecclesiastical institution until modern times. Its archive, which is partly preserved to this day, is both the most extensive of its kind to survive in Iceland and uniquely remained in place for almost eight centuries, making it possibly the longest operated archive in the Nordic countries. The Icelanders may be better known for their sagas and mythological poetry, but their industrious literacy certainly extended to creating bureaucratic documents in accordance with the Roman tradition. French Benedictines were among the first in the world to turn the art of archival management into an academic discipline, and the Icelandic Professor Árni Magnússon (d. 1730), who is best known for his great collection of Old Icelandic manuscripts, was the first Nordic scholar to employ their methods effectively, which he used to investigate the Archive of Þingeyrar. Surveying the history of this Icelandic archive gives us insight into a constitutive science fundamental for our access to the past. Full article

Background: In 2020, in 27 European Union (EU) Member States, melanoma accounted for 4% of all new cancer cases and 1.3% of all cancer deaths, making melanoma the fifth most common malignancy and placing it in the 15 most frequent causes of cancer deaths in the EU-27. The main aim of our study was to investigate melanoma mortality trends in 25 EU Member States and three non-EU countries (Norway, Russia, and Switzerland) in a broad time perspective (1960–2020) in a younger (45–74 years old) vs. older age group (75+). Methods: We identified melanoma deaths defined by ICD-10 codes C-43 for individuals aged 45–74 and 75+ years old between 1960–2020 in 25 EU Member States (excluding Iceland, Luxembourg, and Malta) and in 3 non-EU countries—Norway, Russia, and Switzerland. Age-standardized melanoma mortality rates (ASR) were computed using the direct age-standardization for Segi’s World Standard Population. To determine melanoma-mortality trends with 95% confidence intervals (CI), Joinpoint regression was applied. Our analysis used the Join-point Regression Program, version 4.3.1.0 (National Cancer Institute, Bethesda, MD, USA). Results: Regardless of the considered age groups, in all investigated countries, in general, melanoma standardized mortality rates were higher for men than women. Considering the age group 45–74, the highest number of countries was characterized by decreasing melanoma-mortality trends in both sexes—14 countries. Contrarily, the highest representation of countries in the age group 75+ was connected with increasing melanoma-mortality trends in both sexes—26 countries. Moreover, considering the older age group—75+—there was no country with a decreasing melanoma mortality in both sexes. Conclusions: Investigated melanoma-mortality trends vary in individual countries and age groups; however, a highly concerning phenomenon—increasing melanoma-mortality rates in both sexes—was observed in 7 countries for the younger age group and in as many as 26 countries for the older age group. There is a need for coordinated public-health actions to address this issue. Full article

Icelandic prose narratives from the 13th and 14th centuries are replete with instances of metamorphosis, humans transforming into animals, or changing shape in an indeterminate way. Sources indicate that the transformation is not merely corporeal but is also spiritual. In this paper, the Old Norse lexicon of transformation, such as the words hamrammr, hamslauss, and hamstoli, will be closely examined. Full article

For a long time now, Old Norse literature has often been colonized and misappropriated by modern right-wing political groups for their own ideology, symbolism, and public appearance. A critical reading of Icelandic sagas, however, easily demonstrates that those public strategies are very short-sighted, misleading, and outright dangerous for our democratic society. To stem the flood of misinformation regarding the Viking world and its literature, this article joins a small but forceful chorus of recent scholars who are hard at work deconstructing this politicization of saga literature by way of offering new readings of those texts in which the very Viking ideology is actually exposed by the poets, rejected, and supplanted by new forms of social interactions predicated on a legal system and an operation with rationality in the public sphere.

Scandinavian Studies today are divided into (at least) three areas, which should ideally also be represented by their own chairs at the universities, if one wants to cover the subject as broadly as possible. Likewise, the four languages, Danish, Icelandic, Norwegian and Swedish, should be offered to a certain extent. Scandinavian Studies, however, belong to the so-called “small subjects”, and financial and personnel resources are often limited. In addition, the federal states (Bundesländer) have an influence on the equipment of the universities. The subject of Scandinavian Studies can therefore be structured very differently at the individual universities. It is largely undisputed that foreign language skills are an important factor in promoting international understanding. As well, language skills are an absolute foundation in all aspects of a philological subject. Nevertheless, language teaching at universities is generally under pressure, and questions arise about its justification. This is true for both modern and ancient languages. In our article, we mainly describe the positions of Old and modern Icelandic within Scandinavian Studies, which differ greatly. This is mainly due to traditions within Scandinavian Studies and the institutions at which they are taught. Considerations are made regarding the legitimacy of these areas and their connections with other parts of the subject. Full article

A risk assessment (RA) was conducted to estimate the risk associated with methylmercury (MeHg) exposure of vulnerable European populations, using Human Biomonitoring (HBM) data. This RA was performed integrating published data from European HBM surveys and earlier EFSA approaches (EFSA 2012). Children/adolescents (3 to 17 years old) and women of childbearing age (18 to 50 years old) were selected as relevant study population groups for this RA. Two types of HBM datasets were selected: HBM studies (n = 18) with mercury (Hg) levels (blood and hair, total Hg and/or MeHg) in the general population in different EU countries and the DEMOCOPHES harmonized study in child–mother pairs (hair, total Hg) in 17 EU countries as a reference. Two approaches were included in the RA strategy: the first one was based on estimations of the fraction of children/adolescents and women of childbearing age, respectively, from the EU general population exceeding the HBM-I value established by the German Human Biomonitoring Commission, measured as Hazard Quotients (HQ); and the second approach was based on estimations of the fraction of the two population groups exceeding the Tolerable Weekly Intake (TWI) (or their equivalent to Tolerable Daily Intake (TDI)) defined by EFSA in 2012. The HQ approach showed that for both groups, the risk varies across EU countries and that some EU areas are close to or exceeding the exposure guidance values. This is the case of Spain and Portugal, which showed the highest HQ (GM and/or P95), probably due to their higher fish consumption. Results from the EFSA approach show that hair values of children/adolescents and women of childbearing age (both in selected HBM studies and in DEMOCOPHES study) are below the TDI of 1.9 µg/g; therefore, in general, the European population does not exceed the daily average/intake dose for MeHg and/or Hg. A possible risk underestimation was identified in our assessment since for many studies no data on P95 were available, causing loss of relevant information for risk characterization on the upper bound. In addition, data from other European countries also with high seafood consumption, such as France, Greece or Iceland, were not available. For this reason, further RA refinement is needed with harmonized and more widespread HBM data to account for differences in European exposure and associated risks, so that interventions to protect vulnerable citizens, can be applied.

Traditionally, adolescent drinking cultures differed between Nordic and Mediterranean countries; the former being characterised by low volume and relatively frequent heavy episodic drinking (HED). Across these drinking cultures, we examined the associations between alcohol volume and HED with respect to (i) secular trends at the country level and (ii) individual-level associations over time. The data stem from the European School Survey Project on Alcohol and Other Drugs (ESPAD) conducted among 15–16-year-olds in Finland, Iceland, Norway, Sweden, France and Italy, employing six cross-sectional surveys from 1999 to 2019 (n = 126,126). Both consumption volume and HED frequency decreased in all Nordic countries and displayed a curvilinear trend in France and Italy. In all countries, consumption volume and HED correlated highly over time at the country level. At the individual level, the correlation was positive but with a varying magnitude over time and between countries. In 1999/2003, the alcohol volume–HED correlation was significantly higher in the Nordic compared to the Mediterranean countries but became significantly weaker in Finland, Norway and Sweden and remained stable in France, Iceland and Italy during the period. In conclusion, while trends in consumption volume and drinking patterns went hand in hand at the aggregate level, the association at the individual level weakened over time in several Nordic countries, along with the substantial decline in adolescent drinking since 2000.

The Sustainable Development Goals (SDGs) represent a bridging point between the old, neoclassical, growth-based model of the economy and newer, emerging paradigms, such as the well-being economy. The importance of growth in Gross Domestic Product (GDP) is recognized within the SDGs, however, in addition, Target 19 of Goal 17 advocates the adoption of alternative measures of economic well-being. The Genuine Progress Indicator (GPI) has been found to be the indicator of alternative economic well-being most aligned with the SDGs. On the basis that increased, high-quality energy use leads to expanded macro-economic activity, as measured by GDP, this study conducts a conceptual exploration of the extent to which the pursuit of sustainable energy development (SED) can enhance GPI outcomes. Based on a recent Icelandic GPI study, a total of 46 SED themes were found to be linkable to 16 of its 39 sub-indicators, including 8 cost deductions and 7 benefit additions. The frequency of these was as follows: sustainable energy production (10), sustainable energy consumption (10), energy security (8), nature conservation (8), social benefits (7) and economically efficient energy system (3). The main implication of the study outcomes is that the pursuit of SED is likely to have considerable benefits in terms of fulfilling energy and climate policy, but also co-benefits with regard to the promulgation of economic and societal well-being, as reflected in the GPI. These outcomes, although applicable to Iceland, have ramifications for all nations who are simultaneously striving for greater economic prosperity, whilst tackling climate change and striving to deliver equitable, environmentally sound and resilient energy systems.

New tobacco and nicotine products have emerged on the market in recent years. Most research has concerned only one product at a time, usually e-cigarettes, while little is known about the multiple use of tobacco and nicotine products among adolescents. We examined single, dual, and triple use of cigarettes, e-cigarettes, and snus among Nordic adolescents, using data of 15–16-year-olds (n = 16,125) from the European School Survey Project on Alcohol and other Drugs (ESPAD) collected in 2015 and 2019 from Denmark, Finland, Iceland, Norway, Sweden, and the Faroe Islands. Country-specific lifetime use of any of these products ranged between 40% and 50%, and current use between 17% and 31%. Cigarettes were the most common product in all countries except for Iceland, where e-cigarettes were remarkably more common. The proportion of dual and triple users was unexpectedly high among both experimental (24%–49%) and current users (31–42%). Triple use was less common than dual use. The users’ patterns varied somewhat between the countries, and Iceland differed substantially from the other countries, with a high proportion of single e-cigarette users. More knowledge on the patterns of multiple use of tobacco and nicotine products and on the potential risk and protective factors is needed for targeted intervention and prevention efforts.

Environmental settings influence children’s and adolescents’ physical activity (PA) in neighborhoods and schoolyards. This study aimed to explore the main characteristics of schoolyards in six Nordic–Baltic countries, to document how those facilities provide affordances for PA in 7–18 year–old schoolchildren, and how the schoolyard meets children’s preferences. One schoolyard was studied in each included country: Iceland, Norway, Finland, Lithuania, Latvia, and Estonia. The affordances, facilities, and equipment for PA in schoolyards were identified through orthophoto maps and standard registration forms. Children’s preferences were collected through group interviews at each participating school. A common design of schoolyards across countries indicated mostly flat topography with sparse vegetation and green areas dominated by large traditional sport arenas such as a football field, areas suitable for ball games, and track and field activities. Green spaces and varied topography were more prominent in Nordic countries. Across nationalities, the responses from pupils regarding the schoolyard were similar: they liked it though they wished for more variety of activities to do during recess. National regulations/recommendations for schoolyard design differed across the countries, being more restricted to sport fields and sport-related activities in Latvia and Lithuania, while in Nordic countries, the recommendations focused more on versatile schoolyard design.

The aim of the study was to assess the prevalence of online exposure to pornography in European adolescents and its relationship to sociodemographic and psychopathological correlates. A cross-sectional school-based survey of 10,930 adolescents (5211 males/5719 females), aged 14–17 years old (mean age 15.8 ± 0.7) was carried out in six European countries (Greece, Spain, Poland, Romania, the Netherlands, and Iceland). Anonymous self-completed questionnaires covered exposure to pornography, internet use and dysfunctional internet behavior, and psychopathological syndromes (measured by Achenbach’s Youth Self-Report). The prevalence of any online exposure to pornography was 59% overall and 24% for exposure at least once a week. The likelihood of online exposure to pornography was greater in male adolescents, heavier internet users, and those who displayed dysfunctional internet behavior. Country-specific analyses confirmed that the gender effect existed in every country, although its strength varied, from an odds ratio of 1.88 in Poland to 14.9 in Greece. Online exposure to pornography was shown to be associated with externalizing problem scale scores, especially rule-breaking and aggressive behavior, but also associated with higher scores in competences, namely activities and social competence. Exposure to pornography is ubiquitous, more relevant to boys, and is associated with both positive qualities/competences and externalizing behavioral problems. Full article

Positive mental health is central to adolescent well-being. The present study examines the prevalence of loneliness and positive mental health indicators (mental well-being and self-esteem) in four Nordic countries and associations between loneliness, mental well-being, and high self-esteem. This study is based on data from the Health Behaviour in School-aged Children (HBSC) study which was conducted in 2018 in Denmark, Finland, Iceland, and Sweden. Participants were 5883 15-year-old boys and girls. To examine the associations between loneliness, mental well-being, and self-esteem, structural equation modeling (SEM) was applied. In the comparison of Nordic countries, the prevalence of loneliness was highest among Finnish and Icelandic adolescents. High mental well-being and high self-esteem were most prevalent in Denmark and Sweden. In general, boys scored higher on positive mental health indicators and girls on loneliness. Loneliness was also a strong indicator of low mental well-being and low self-esteem in all Nordic countries. Loneliness is not only associated with mental health problems such as anxiety and depression, but it is also a risk factor for adolescents’ positive mental health. Positive mental health is important for healthy maturation and there is a need to develop initiatives to reduce adolescent loneliness and so support positive development. Full article
