Canadian Inuit have transited from a physically active hunter-gatherer subsistence lifestyle into sedentary ways of life. The purpose of the current study was to measure physical activity levels among Nunavut Inuit adults, and explore the socio-cognitive and environmental factors influencing the number of steps taken per day.
Inuit and non-Inuit adults ( = 272) in Nunavut participated in a seven-day pedometer study during summer and winter seasons. Participants were asked to complete the Neighbourhood Environmental Walkability Scale (NEWS) and Behavioral Regulation in Exercise Questionnaire (BREQ-3). Data analyses included descriptive statistics, hierarchical linear regression, and tests of mediation effects.
Participants had limited to low activity at a rate of 5027 ± 1799 and 4186 ± 1446 steps per day, during summer and winter, respectively. There were no seasonal and age effects on the number of steps. Gender effects and community differences were observed. Perceived infrastructure and safety as well as land use mix diversity were found to be positive environmental correlates of steps taken, which were partially mediated by identified motivational regulation.
Physical activity levels among Nunavut adults are generally low, but can be promoted by improving the external physical environment and internal motivational regulation.
加拿大因纽特人已经从以体力活动为主的狩猎采集为生的生活方式转变为久坐不动的生活方式。本研究的目的是测量努纳武特因纽特成年人的身体活动水平，并探讨影响每天步数的社会认知和环境因素。
努纳武特的因纽特人和非因纽特成年人（=272）参与了夏季和冬季为期七天的计步器研究。参与者被要求完成邻里环境步行能力量表（NEWS）和运动行为调节问卷（BREQ-3）。数据分析包括描述性统计、分层线性回归和中介效应检验。
参与者的活动量有限，夏季和冬季每天分别为 5027±1799 步和 4186±1446 步。性别和年龄对步数没有影响。观察到了性别效应和社区差异。感知的基础设施和安全以及土地利用多样性被发现是与步数相关的积极环境因素，这部分通过识别的动机调节得到了部分中介。
努纳武特成年人的身体活动水平普遍较低，但可以通过改善外部物理环境和内部动机调节来促进。
