BACKGROUNDObesity and insulin resistance are linked with mood disorders, and elevated concentrations of branched-chain (BCAAs) and aromatic amino acids (AAAs). Our study aimed to prospectively assess the relationship between childhood plasma BCAAs and AAAs and behavioral problems in young Inuit from Nunavik.METHODSWe analyzed data on 181 children (mean age 11.4 years at baseline) involved in the Nunavik Child Development Study. Plasma BCAA and AAA concentrations were measured in childhood (2005-2010). BCAA/AAA tertiles - the ratio of total BCAAs to AAAs-were considered as a surrogate categorical independent variable...

BACKGROUND: Hospital admissions for respiratory syncytial virus infection result in large health expenditures for Inuit infants. Palivizumab has been shown to be highly effective in reducing such admissions in preterm Inuit infants. We performed a cost-effectiveness analysis estimating the incremental cost-effectiveness ratio (ICER) for palivizumab prophylaxis per admission related to respiratory syncytial virus avoided in healthy term infants across the Canadian Arctic. METHODS: We compared universal palivizumab prophylaxis in term infants less than 6 months of age to no prophylaxis in 8 Arctic regions: the Northwest Territories, Nunavut, Nunavut without Iqaluit, the 3 subregions of Nunavut (Kitikmeot, Kivalliq and Qikiqtaaluk), the Qikiqtaaluk Region without Iqaluit, and Nunavik (northern Quebec)...

BACKGROUND: Radon is the second leading cause of lung cancer after smoking. In Canada, the health authorities have no access to comprehensive profile of the communities built over uranium-rich micro-geological settings. The present indoor radon monitoring guideline is unable to provide an accurate identification of health hazards due to discounting several parameters of housing characteristics. OBJECTIVE: To explore indoor radon levels in a micro-geological setting known for high uranium in bedrock and to develop a theoretical model for a revised radon testing protocol...

BACKGROUND: Black Tickle-Domino is an extremely water-insecure remote Inuit community in the Canadian subarctic that lacks piped-water. Drinking water consumption in the community is less than a third of the Canadian national average. Water insecurity in the community contributes to adverse health, economic, and social effects and requires urgent action. OBJECTIVES: To test the ability of domestic rainwater harvesting (DRWH) for the first time in the subarctic with the goal of improving water access and use in the community...

An exponential level increase of the ubiquitous halogenated flame retardant (HFR) class polybrominated diphenyl ether (PBDE) has been documented during the 1990s in endangered belugas (Delphinapterus leucas) from the St. Lawrence Estuary (SLE), Eastern Canada. The recent worldwide bans and regulations of PBDE mixtures led to their replacement by alternative HFRs (so-called emerging HFRs) that are increasingly being reported in various environmental compartments. There are, however, limited knowledge on the spatial and temporal trends of PBDEs and emerging HFRs in cetaceans, especially after restrictions on PBDE usage...

INTRODUCTION: The Public Health Agency of Canada adapted a Finnish diabetes screening tool (FINDRISC) to create a tool (CANRISK) tailored to Canada's multi-ethnic population. CANRISK was developed using data collected in seven Canadian provinces. In an effort to extend the applicability of CANRISK to northern territorial populations, we completed a study with the mainly Inuit population in the Kitikmeot region of Nunavut. METHODS: We obtained CANRISK questionnaires, physical measures and blood samples from participants in five Nunavut communities in Kitikmeot...

INTRODUCTION: Aboriginal children in Canada experience significant disparities in health in comparison to their mainstream peers. As Aboriginal communities and agencies strive to improve health, it is important to measure the impact of new programs and services. Since many Aboriginal children live in rural and remote communities, it is important that communities have access to measurement tools that are relevant and feasible to implement in these contexts.<b> </b>The Aboriginal Children's Health and Well-being Measure (ACHWM) was developed to meet the need for a culturally relevant measure of health and wellbeing for Aboriginal children (ages 8-18 years) in Canada...

BACKGROUND: Drinking water insecurity and related health outcomes often disproportionately impact Indigenous communities internationally. Understanding media coverage of these water-related issues can provide insight into the ways in which public perceptions are shaped, with potential implications for decision-making and action. This study aimed to examine the extent, range, and nature of newspaper coverage of drinking water security in Canadian Indigenous communities. METHODS: Using ProQuest database, we systematically searched for and screened newspaper articles published from 2000 to 2015 from Canadian newspapers: Windspeaker, Toronto Star, The Globe and Mail, and National Post...

FADS genes encode fatty acid desaturases that are important for the conversion of short chain polyunsaturated fatty acids (PUFAs) to long chain fatty acids. Prior studies indicate that the FADS genes have been subjected to strong positive selection in Africa, South Asia, Greenland, and Europe. By comparing FADS sequencing data from present-day and Bronze Age (5-3k years ago) Europeans, we identify possible targets of selection in the European population, which suggest that selection has targeted different alleles in the FADS genes in Europe than it has in South Asia or Greenland...

BACKGROUND: Selenium (Se) has been reported to protect against the neurotoxicity of mercury (Hg). However, the effect of Se against Hg on cardiovascular diseases remains unclear. Inuit living in the Arctic have high exposure to both Se and Hg through their marine mammal and fish rich traditional diet. OBJECTIVE: To characterize the co-exposure of Hg and Se among Inuit in Canada and to assess the associations between Hg, Se and cardiovascular health outcomes, including stroke, hypertension, and myocardial infarction (MI)...

BACKGROUND: Inuit interpreters are key players in end-of-life (EOL) care for Nunavik patients and families. This emotionally intensive work requires expertise in French, English and Inuit dialects to negotiate linguistic and cultural challenges. Cultural differences among medical institutions and Inuit communities can lead to value conflicts and moral dilemmas as interpreters navigate how best to transmit messages of care at EOL. OBJECTIVES: Our goal was to understand the experience of Inuit interpreters in the context of EOL care in Nunavik in order to identify training needs...

The occurrence of thyroid disorders relies on I nutrition and monitoring of all populations is recommended. Measuring I in urine is standard but thyroglobulin in serum is an alternative. This led us to assess the reliability of studies using serum thyroglobulin compared with urinary I to assess the I nutrition level and calculate the number of participants needed in a study with repeated data sampling in the same individuals for 1 year. Diet, supplement use and life style factors were assessed by questionnaires...

Type 2 diabetes is a chronic metabolic disease that is of increasing concern in Inuit communities. Behavioural factors such as physical inactivity and poor diet are well-known risk factors. Exposure to persistent organic pollutants (POPs) has emerged as an additional factor in the pathogenesis of diabetes. In this study, association between polychlorinated biphenyls (PCBs) and p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE) with diabetes in Canadian Inuit was examined. Data from the Adult Inuit Health Survey (2007-2008) of Inuit participants from the Canadian Arctic were analyzed...

CONTEXT: Osteoporosis is a frequent disease in many populations. The hallmark is fragility fractures, which are harbingers of future fractures, disability, mortality and cost on society. The occurrence increases with age, low vitamin D level and smoking. Smoking rates are high, vitamin D is low and life expectancy is rising steeply in Greenland, as is the need for focus on osteoporosis. We report a case that uses a simple and readily available tool to diagnose osteoporosis at the hospital in Sisimiut, a town of 5000 inhabitants on the west coast of Greenland...

Using data from the 1991, 2001 and 2012 Aboriginal Peoples Survey, this study examines the prevalence of smoking among Inuit aged 15 or older, by location of residence, sex and age group. Overall, the prevalence of daily smoking was significantly lower in 2012 than in 1991; this was true for Inuit living inside and outside Inuit Nunangat, for men and women, for most age groups, and for those in all Inuit regions except Nunavik. The average number of cigarettes smoked per day by daily smokers decreased steadily and significantly over time, except among those living outside Inuit Nunangat or in Nunavik, and those aged 55 or older...

When humans moved from Asia toward the Americas over 18,000 y ago and eventually peopled the New World they encountered a new environment with extreme climate conditions and distinct dietary resources. These environmental and dietary pressures may have led to instances of genetic adaptation with the potential to influence the phenotypic variation in extant Native American populations. An example of such an event is the evolution of the fatty acid desaturases (FADS) genes, which have been claimed to harbor signals of positive selection in Inuit populations due to adaptation to the cold Greenland Arctic climate and to a protein-rich diet...

BACKGROUND: Increasing longevity for Inuit living in Nunavik, northern Quebec, has resulted in heightened rates of cancers and chronic diseases necessitating complex treatments. Consequently, end-of-life (EOL) care, once the domain of Inuit families and communities, has come to include professionalized healthcare providers with varying degrees of awareness of factors to consider in providing care to Inuit populations. OBJECTIVE: To better understand the factors shaping EOL care in Nunavik to support the development of a sustainable model of care...

BACKGROUND: Peripartum cardiomyopathy (PPCM) is a heterogeneous condition characterized by heart failure and left ventricular dysfunction (left ventricular ejection fraction [LVEF] < 45%) in the absence of an alternative cause and a previous diagnosis of cardiomyopathy. The Aboriginal population (Inuit, First Nations, Metis) of Canada often has barriers to health care, which can lead to delays in diagnosis and treatment. Our objectives are to describe PPCM in a Canadian population, and to determine if Canadian Aboriginal women have worse clinical outcomes than non-Aboriginal women...
