Abstract
The ubiquitous presence of legacy and emerging persistent organic pollutants (POPs) in the environmental matrices poses a potential hazard to the humans and creating public health concerns. The present study aimed to evaluate dioxins, dioxin-like polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and chlorinated paraffins (CPs) concentrations in serum of women (postpartum, pregnant and non-pregnant) from Northern Norway to better understand their exposure and contamination status as well as temporal trends across 2007-2009 (MISA 1) to 2019 (MISA 2). Sixty-two blood samples from the MISA 1 cohort and 38 samples from MISA 2 were randomly selected in this study (n = 100). Ninety samples from postpartum (MISA 1) and pregnant women (MISA 2) were randomly combined into 9 pools, with 9-11 individual samples contributing to each pool keeping the groups of pregnant and postpartum women. Remaining 10 samples from non-pregnant women (MISA 2) were allocated into separate group. Geometric mean, minimum and maximum were used to describe the serum concentrations of pooled POPs in MISA cohort. Mann-Whitney U test and independent sample t-test were applied for trend analysis of blood levels of POPs between MISA 1 and MISA 2. We found the serum concentrations of selected POPs in this study to be at lower range. Serum concentrations of dibenzo-p-dioxins (PCDDs) (p = 0.010), polychlorinated dibenzofurans (PCDFs) (p = 0.002), dioxins-like PCBs (p = 0.001), hexachlorobenzene (HCB) (p < 0.001) and p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE) (p = 0.002) were decreased between the studied time. In contrast, the serum concentrations of medium chain chlorinated paraffins showed an increasing trend between 2007 and 2009 and 2019 (p = 0.019). Our findings report a particular concern of emerging contaminant medium chain chlorinated paraffin exposure to humans. Future observational studies with repeated measurements of chlorinated paraffins in general populations worldwide and large sample size are warranted.

Abstract
Background Few population-based studies have assessed dietary behaviors in the rural multiethnic population of Northern Norway. The present study determined dietary patterns and investigated their association with Sami ethnicity, sociodemographic factors, and lifestyle factors in a multiethnic population in rural Northern Norway. Methods This cross-sectional study included 4504 participants of the SAMINOR 2 Clinical Survey (2012–2014) aged 40–69 years. All participants completed a lifestyle and food frequency questionnaire. Dietary patterns were determined using principal component analysis. Associations between food patterns and ethnicity, sociodemographic factors, and lifestyle factors were examined by multiple linear regression. Results Six dietary patterns were identified that accounted for 28% of the variability in food intake in the study sample: ‘processed meat/westernized’, ‘fish/traditional’, ‘fruit/vegetables’, ‘reindeer/traditional’, ‘bread and sandwich spreads’, and ‘sweets and bakery goods’. The ‘reindeer/traditional’ pattern was most common among the inland Sami population. The ‘fish/traditional’ pattern was most common among costal multiethnic Sami and least common among inland Sami and among women independent of ethnicity. The ‘fish/traditional’ pattern was also positively associated with older age, high education level, small household size, and smoking. Adherence to the ‘processed meat/westernized’ pattern was lower among inland Sami than inland/coastal non-Sami; no ethnic differences in adherence to this pattern were found between costal multiethnic Sami and inland/coastal non-Sami. Unhealthy lifestyle factors, like low physical activity level and smoking, and younger age were mainly associated with the ‘processed meat/westernized’ pattern, whereas socioeconomic factors like low education, low gross annual household income, and large household size were related to the ‘sweets and bakery goods’ pattern. Male gender, low education level, and smoking were associated with the ‘bread and sandwich spreads’ pattern. The ‘fruit/vegetables’ pattern was characterized by healthy dietary choices and a health-conscious lifestyle, and was more common in women with a high education level and income. Conclusions Adherence to the six identified dietary patterns was characterized by different sociodemographic and lifestyle factors. Ethnicity, in combination with geographical region of residence, was associated with dietary behaviors. This study provides knowledge that will be useful in future studies on dietary patterns related to chronic diseases in the rural population of Northern Norway.

Abstract
Through the construction of a socio-ecological timeline for the Porsanger fjord ecosystem, this article illustrates the different ways in which environmental and social-ecological changes have influenced the adaptations of rural households in coastal Sami communities in Finnmark, north Norway. The main finding is that, although environmental change in the form of seal invasions and dwindling fish stocks directly impacted the fisheries, the introduction of a new vessel quota system decisively changed adaptive capacity and coastal Sami household adaptation strategies. These changes represented a tipping point for the social-ecological system in the period between 1986 and 1990. It is thus important to discuss the ways in which governance systems may facilitate actions to adapt to climate and biodiversity change and foster sustainable rural livelihood systems in coastal Norway. Based on traditional and local ecological knowledge on the state of the ecosystem prior to the tipping point, two relevant actions to increase the resilience of the system were identified: ensuring the possibility of re-entry into fisheries as part of rural livelihood combinations, and ecological restoration of kelp beds. Flexible diversification of livelihoods allows exploitation of a range of adjacent species without large investments in a fossile fuel-driven fisheries economy. Investing in regrowth of macroalgae to foster cod nursery areas and increase carbon sequestration can be a relevant alternative for communities that are interested in contributing to climate change mitigation on a larger scale.

Abstract
Rough weather conditions in the subarctic areas of Norway may influence on the risk of wrist fracture. We implemented data from the Norwegian System of Patient Injury Compensation (NPE). All claims due to wrist surgery, performed at the public hospitals in Northern Norway, during 2005-2014 were analyzed. We employed the ICD-10 classification codes S52.5 (fracture of distal end of radius) and S52.6 (fracture of distal end of radius and ulna). Treatment was defined by NCSP codes. 84 patients (0.3%) complained. Females complained four times more often than males did (P = 0.005) and received five times more frequently a compensation (P < 0.001). NPE accepted 34 claims (40%) for injury compensation (0.1% of patients). The percentage of claims accepted for compensation decreased from 48% to 30% during study period, probably due to delay in filling claims. The main causes of complains were pain, reduced range of motion, malfunction and weakness (35/84). The main causes of compensation were "operative treatment should have been performed" (14/34) and "wrong operative method applied" (13/34). The mean amount per compensation was €14,927 (€0-€52,995). Stonger focus on quality of care, updated guidelines and shared decission-making may reduce the number og complains and compensations.

Abstract
Little is known about how people living in the aftermath of cancer treatment experience and manage worries about possible signs of cancer relapse, not as an individual enterprise but as socially embedded management. One-year ethnographic fieldwork was conducted in a coastal village of under 3000 inhabitants in northern Norway. Ten villagers who had undergone cancer treatment from six months to five years earlier were the main informants. During fieldwork, the first author conducted qualitative, semi-structured monthly interviews with them, and participated in their everyday activities and relationships, including families, friends and co-villagers. In this article, we contemplate human emotions as arising in contexts of transactions, capable of creating social realities. By including this perspective, we highlight how people who recover from cancer construct and experience worry about possible relapse in relation to close family members, friends and co-villagers in the socially closely-knit and relatively isolated village. These emotional experiences emerge through relationships with others have communicative characteristics and take place in interaction with the social environment of their village. While informants attempt to protect family members by avoiding sharing worries with them, they express the need to share their worries within friendships. However, they experience both comfort and challenges in managing their worries in relation to acquaintances in the village. Overall, the study enhances understanding of the social embeddedness of emotions in everyday life, by revealing how worries of relapse of cancer configure and relate to various social contexts.

Abstract
OBJECTIVE To estimate current food intake in the population of northern Norway and to investigate the impact of self-perceived Sami ethnicity and region of residence on food intake. DESIGN The data are part of the second cross-sectional survey of the Population-based Study on Health and Living Conditions in Regions with Sami and Norwegian Populations (the SAMINOR 2 Clinical Survey, 2012-2014). Food intake was assessed by an FFQ. Ethnic and regional differences in food intake were studied by sex-specific, multivariable-adjusted quantile regression models. SETTING Ten municipalities (rural northern Norway). SUBJECTS Males (n 2054) and females (n 2450) aged 40-69 years (2743 non-Sami, 622 multi-ethnic Sami, 1139 Sami). RESULTS The diet of Sami participants contained more reindeer meat, moose meat, food made with animal blood and freshwater fish; and contained less lean fish and vegetables. In the inland region, the consumption of reindeer meat was greatest in Sami participants, followed by multi-ethnic Sami participants and non-Sami participants, who had the lowest consumption (median 25, 12 and 8 g/d, respectively). Compared with the inland region, fish roe/liver intake was higher in the coastal region and lean fish intake was twice as high (41 and 32 g/d in males and females, respectively). CONCLUSIONS When compared with non-Sami participants, those with solely self-perceived Sami ethnicity reported a significantly different intake of several foods, especially reindeer meat in the inland region. Multi-ethnic Sami tended to have similar diets to non-Sami. Residence in the coastal region predicted higher fish and roe/liver intake.
