To examine differences in physical activity patterns among Inuit in Greenland in relation to social transition. The Inuit in Greenland are an indigenous population in the circumpolar north who are experiencing rapid social transition.
Physical activity patterns were assessed by the International Physical Activity Questionnaire (long version). The population was divided into six groups according to different stages of social change, measured on the basis of education, current residence and occupation. Data were collected in a country-wide cross-sectional population survey among adult Inuit in Greenland from 2005 to 2009.
Men with long vocational or academic education living in towns (latest stage of social change) spent significantly less time on occupational physical activity (p = 0.001) compared with hunters and fishermen in villages (earliest stage of social change) (trend test p = 0.01). Women in the latest stage of change spent significantly less time on domestic physical activity (p < 0.001) (trend test p = 0.06) compared with women in the earliest stage of social change. This was also found for physical activity during transportation (p = 0.02 and p = 0.01 for men and women, respectively). No significant difference was found for leisure time physical activity. Men and women in the latest stage of social change spent more time on sedentary activity (p < 0.001).
Differences in physical activity patterns among Inuit in Greenland included decreasing time spent on domestic and occupational physical activity and increasing time spent on sedentary activities along with social change. Knowledge of changes in physical activity patterns in relation to social transition is important in prevention of obesity, type 2 diabetes and lifestyle diseases.
探讨格陵兰因纽特人在社会转型过程中身体活动模式的差异。格陵兰因纽特人是北极圈的一个土著民族，他们正在经历快速的社会转型。
身体活动模式通过国际体力活动问卷（长版）进行评估。根据教育、当前居住地和职业的不同，将人口分为六个群体，以衡量社会变化的不同阶段。数据来自于 2005 年至 2009 年期间在格陵兰岛进行的一项全国性的成年人横断面人群调查。
从事长期职业或学术教育、居住在城镇（社会变化的最新阶段）的男性与居住在村庄的猎人及渔民（社会变化的最早阶段）相比，在职业体力活动上花费的时间显著减少（p = 0.001）（趋势检验 p = 0.01）。处于社会变革最新阶段的女性在做家务活动上花费的时间显著减少（p < 0.001）（趋势检验 p = 0.06），与社会变革最早阶段的女性相比。在交通活动中的体力活动也存在同样的情况（男性和女性分别为 p = 0.02 和 p = 0.01）。而休闲时间的体力活动没有显著差异。处于社会变革最新阶段的男性和女性花在久坐活动上的时间更多（p < 0.001）。
格陵兰因纽特人身体活动模式的差异包括随着社会变革，家务和职业体力活动时间减少，久坐活动时间增加。了解身体活动模式与社会转型之间的变化对于预防肥胖、2 型糖尿病和生活方式疾病非常重要。
