“…Our data on prevalence of obesity are in line with previous studies of Inuit women (28,29). The cross-sectional International Polar Year Inuit Health Survey for adults in 2007–2008 showed that 41.6% of Canadian Inuit women had a BMI ≥30 kg/m 2 (30).…”

BackgroundThe prevalence of obesity and obesity-related conditions varies by population groups. Indigenous women of the circumpolar north are believed to be at high risk of obesity.ObjectiveWe studied, first the obesity prevalence in indigenous Arctic women, Nenets, compared to urban Russian women. Second, the association between obesity and cardiometabolic risk factors in the combined group of Nenets and Russian women. Third, ethnic differences in the association between obesity and cardiometabolic risk factors.DesignCross-sectional study performed in 2008–2009. Subjects: 93 Nenets women, aged 19–77 (the indigenous village, the Nenets Autonomous Area) and 132 Russian women, aged 21–72 (Arkhangelsk city). Obesity was defined as body mass index (BMI)≥30 kg/m2, waist circumference (WC)≥88 cm and or waist-to-hip ratio (WHR)≥0.85%. We assessed associations between obesity and cardiometabolic risk factors by linear and logistic regression models that included covariates of ethnicity, age, smoking and physical activity. We also tested for interaction between obesity measurements and ethnicity.ResultsPrevalence of obesity estimated through BMI, WC and WHR were 42.5, 45.3 and 41.9% in Nenets and 34.4, 46.4 and 29.5% in Russians, respectively, with no differences found. BMI, WC and WHR associated positively with triglycerides, fasting insulin and Homeostasis Model Assessment of Insulin Resistance index. In addition, BMI and WC correlated negatively with high-density lipoprotein cholesterol and positively with systolic blood pressure and apolipoprotein B/apoliporotein A–I ratio. WC explained significant variation in fasting glucose (FG) level. BMI predicted type 2 diabetes history. FG level associated strongly with ethnicity and was found to be higher in Russians.ConclusionsWe found no differences in prevalence of obesity between Nenets and Russian females. Obesity was associated with cardiometabolic risk factors independently of ethnicity in the sample studied. There was no link between obesity measurements and ethnicity.

“…This pattern has also been reported among adult Greenlanders (4, 18, 19). Earlier studies among adult Canadians and Alaskan Inuits have shown that women have a higher prevalence of obesity, but lower prevalence of overweight than men (20, 21).…”

ObjectivesTo estimate the proportion of gender-specific thinness, overweight and obesity among children born in 2005 at school entry in Greenland and to compare figures between the capital, Nuuk, with the rest of Greenland.Study designA cross-sectional study based on data from Electronic Medical Records (EMR).MethodsAll children born in 2005 with permanent address in Greenland at the time of data extraction with a registered weight and height in EMR from January 1st 2011 to January 31st 2013 were included in the study. Information about height without shoes and weight in light indoor clothing was obtained. Body Mass Index (BMI) was calculated. Participants were categorized into age and gender-specific weight classes based on the International Obesity Task Force (IOTF) cut-offs for child overweight, obesity and thinness.ResultsA total of 842 children born in 2005 were identified. Of those, 72% (N=607, 308 boys and 299 girls) had a recorded weight and height in the study period. In total, 74.6% (71.2–78.1) were categorized as of normal weight. The proportion of children with overweight was 15.8% (12.9–18.7) while 6.8% (4.8–8.8) were obese. In all, 2.9% were categorized as thin. The proportion of overweight among boys (12.7%) was lower (p=0.031) than among girls (19.1%), and boys in Nuuk had a lower median BMI compared to the rest of Greenland. No differences in distribution of age and gender-specific overweight and obesity were observed between the capital and the rest of Greenland.ConclusionNearly 1 quarter of Greenlandic children are overweight or obese at school entry. No differences were observed between Nuuk and the rest of Greenland. Information about weight and height is available in the EMR for the majority of all children at school entry in Greenland. Continuous monitoring of the proportion of overweight and obesity among children using data from the EMR in Greenland is recommended.

“…In a Canadian cross-sectional study, conducted in 2007–2008, the prevalence of overweight and obesity in Inuit adults was 28% and 36%, respectively (24), similar to the results presented here. A study among Greenland Inuit in 2005–2010 suggested that the prevalence of general and central obesity is increasing, especially among women (25). The percentage of women in that study with central obesity was 54%, similar to WATCH study results.…”

Background and Aims Obesity is associated with increased risks of cardiovascular disease, type 2 diabetes, and other chronic diseases. Prevalence estimates for metabolic disorders are well documented in many populations, but Alaska Native groups are understudied. The Western Alaska Tribal Collaborative for Health Study combines data from three Alaska Native study cohorts to assess differences in obesity prevalence and associations with cardiometabolic risk factors by sex. Methods and Results Analyses were based upon a sample of 3985 adult Yup’ik and Inupiat participants with a mean age of 40 years. Prevalence of obesity and metabolic risk factors was assessed according to nationally recognized guidelines. Regression analysis was used to evaluate the association between obesity and cardiometabolic risk factors, including lipids, blood pressure and glucose. The prevalence of obesity (BMI ≥ 30) was significantly higher in women (40%) than men (20%). Only 18.6% of men had a waist circumference (WC) >102cm, while 58% of women had a WC >88cm (p<0.001). Women had higher mean HDL-C and triglyceride levels compared to men, while systolic and diastolic blood pressure, LDL-C, and glucose means were higher in men than in women. In multivariate analyses, BMI and WC were significantly associated with all of the cardiometabolic risk factors, although these associations were more pronounced in men than women. Conclusion The high prevalence of obesity and central adiposity among AN women is an important public health concern. Differences in associations between obesity and cardiometabolic risk factors by sex warrants further investigation to develop effective intervention programs.
