Inuvialuit in Arctic Canada are undergoing nutrition and lifestyle transitions that encourage decreased physical activity (PA) and increased body mass index (BMI), although data specific to PA and BMI within this unique population are not currently available. The present study aimed to characterise current PA and BMI levels in a sample of Inuvialuit adults.
Inuvialuit adults randomly selected from a cross-sectional survey of three communities in the Northwest Territories, Canada, completed an adapted International Physical Activity Questionnaire (IPAQ) and an anthropometric questionnaire to obtain height and weight. Data were analysed using the standardised IPAQ protocol, and the results are presented by gender and age group (≤50 and >50 years).
One hundred and ninety-six Inuvialuit adults [148 women, 48 men; mean (standard deviation (SD)) ages 45 (14) and 41 (14) years, respectively; age range 19-84 years] completed the IPAQ (response rates 65-85%). Seventy-one percent of men and 74% of women allowed height measurements, whilst 81% and 84% allowed weight measurements, respectively; the remainder provided self-reported anthropometrics. Mean (SD) BMIs were 28.6 (7.7) kg/m(2) for males and 30.5 (8.8) kg/m(2) for females. The greatest percentage of participants in both gender and age groups fell into the obese BMI category. Self-reported PA was high, with means for men and participants ≤50 years in the high category of PA and means for women and participants >50 years in the medium category. Almost two-thirds (65%) of participants were classified as being overweight or obese, although 89% reported medium or high levels of PA.
The results obtained in the present study indicate widespread overweight/obesity accompanying high levels of self-reported PA.
加拿大北极地区的因纽特人正在经历营养和生活方式的转变，这鼓励他们减少体力活动（PA）并增加身体质量指数（BMI），尽管目前还没有针对这个独特人群中 PA 和 BMI 的具体数据。本研究旨在描述加拿大西北地区三个社区横断面调查中随机选择的因纽特成年人的当前 PA 和 BMI 水平。
来自加拿大西北地区三个社区的因纽特成年人随机抽取，完成了一份经过改编的国际体力活动问卷（IPAQ）和一份人体测量问卷，以获得身高和体重。数据使用标准化的 IPAQ 方案进行分析，并按性别和年龄组（≤50 岁和>50 岁）呈现结果。
196 名因纽特成年人[148 名女性，48 名男性；平均（标准差（SD））年龄分别为 45（14）和 41（14）岁，年龄范围为 19-84 岁]完成了 IPAQ（应答率为 65-85%）。71%的男性和 74%的女性允许测量身高，而 81%和 84%分别允许测量体重，其余人提供了自我报告的人体测量数据。男性的平均（SD）BMI 为 28.6（7.7）kg/m2，女性为 30.5（8.8）kg/m2。在两性和年龄组中，最大比例的参与者属于肥胖 BMI 类别。自我报告的 PA 水平较高，男性和≤50 岁的参与者中 PA 水平较高，女性和>50 岁的参与者中 PA 水平较高。尽管 89%的人报告说他们有中等或高的 PA，但近三分之二（65%）的参与者被归类为超重或肥胖。
本研究获得的结果表明，普遍存在超重/肥胖现象，同时伴有高水平的自我报告 PA。
