To investigate cross-cultural validity of a simple self-report instrument of physical activity intended to be used in Swedish health care.
A validation study performed in 599 Iraqis (58% men) and 553 Swedes (53% men) aged 30-75 years living in the city of Malmö, Sweden. The self-report instrument by the Swedish National Board of Health and Welfare was compared to corresponding measures assessed from accelerometry as reference.
The agreement between the methods in assessing the participants as sufficiently/insufficiently physically active (cut-point 150 min/week) was 65% in the Iraqis and 52% in the Swedes (p<0.001). The proportion disagreement where the self-reported physical activity was sufficient but insufficient according to the accelerometry was 26% and 45% in Iraqis and Swedes, respectively. Physical activity time (min/week) was overestimated by self-report compared to accelerometry by 71% in the Iraqis and 115% in the Swedes (p<0.001). The smallest and largest overestimation was seen in Iraqi (57%) and Swedish (139%) women, respectively. The deviation of the self-report instrument compared to accelerometry was related to the physical activity level, as the overestimation mainly occurred at lower physical activity.
The self-report instrument proposed by the Swedish National Board of Health and Welfare may overestimate the proportion sufficiently physically active, but to an extent depending on cultural background and gender.
研究一种旨在用于瑞典医疗保健的简单体力活动自我报告工具的跨文化有效性。
在瑞典马尔默市进行的一项验证研究，共纳入 599 名伊拉克人（58%为男性）和 553 名瑞典人（53%为男性），年龄在 30-75 岁之间。将瑞典国家卫生福利委员会的自我报告工具与加速度计评估的相应措施进行比较，作为参考。
在评估参与者是否足够/不足够活跃（150 分钟/周的切点）方面，两种方法的一致性在伊拉克人为 65%，在瑞典人为 52%（p<0.001）。自我报告的体力活动充足但根据加速度计不足的比例差异分别为 26%和 45%，在伊拉克人和瑞典人之间。与加速度计相比，自我报告的体力活动时间（分钟/周）高估了 71%在伊拉克人，高估了 115%在瑞典人（p<0.001）。在伊拉克（57%）和瑞典（139%）女性中，自我报告的高估最小和最大。自我报告工具与加速度计的偏差与体力活动水平有关，因为高估主要发生在较低的体力活动水平。
瑞典国家卫生福利委员会提出的自我报告工具可能会高估足够活跃的比例，但在一定程度上取决于文化背景和性别。
