摘要：Background. The shift away from traditional lifestyle in the Inuit population over the past few decades has been associated with an increased prevalence of coronary heart disease (CHD) risk factors such as obesity, high blood pressure (BP) and diabetes. However, the impact of this transition on the pro-inflammatory marker high-sensitivity C-reactive protein (hs-CRP) has not been documented. Objectives. To examine the prevalence of elevated plasma hs-CRP concentrations in Inuit from Nunavik in the province of Quebec (Canada) and identify anthropometric, biochemical and lifestyle risk factors associated with elevated hs-CRP. Design. A population-representative sample of 801 Inuit residents from 14 villages of Nunavik, aged between 18 and 74 years, was included in the analyses. Subjects participated in a clinical session and completed questionnaires on lifestyle. Multivariate logistic regression was used to determine risk factors for elevated hs-CRP. Results. Elevated plasma hs-CRP concentrations (]2 mg/L) were present in 32.7% (95% confidence interval (CI) 29.535.8) of the Inuit adult population and were more prevalent among women than among men (36.7% vs. 29.0%, p0.007). Multivariate logistic regression analysis indicated that every 1 mmHg increase in systolic BP was associated with a 3% increase in the odds of having hs-CRP concentrations ]2 mg/L in the Inuit population (95% CI 1.011.04). The combination of older age (]50 vs. B30 years) and elevated waist circumference (gender-specific cut-off values) in a multivariate logistic model was also associated with a 13.3-fold increase in the odds of having plasma hs-CRP concentrations ]2 mg/L (95% CI 5.830.9). Conclusions. These data indicate that elevated hs-CRP is relatively prevalent among Inuit with values that are similar to those seen in Canadian Caucasian populations. Sex, age, waist circumference and systolic BP are major factors that increase the risk of this inflammatory phenotype among Inuit from Nunavik, despite their different lifestyle background compared with Caucasians.Keywords: Nunavik; risk factors; waist circumference; aging; sex; systolic blood pressure; Inuit; C-reactive protein; prevalence(Published: 17 October 2012)Citation: Int J Circumpolar Health 2012, 71: 19066 - http://dx.doi.org/10.3402/ijch.v71i0.19066To access the supplementary material to this article, please see Supplementary files under Article Tools.
