Information technology (IT) population in China has expanded rapidly in recent decades, which has suffered severe health problems due to a lack of physical activity (PA). However, little is known about the influence and solutions of PA deficiency. The current research was designed to explore the associations between the amount of PA and potential influenced factors based on the social-ecological model (SEM) and thus to provide rationales for PA promotion.
Six hundred and five IT professionals from five cities of China were surveyed in terms of PA in daily life as well as the potential PA influence factors based on SEM models that consisted of individual, interpersonal, environmental, and political levels in the current study. Hierarchical linear regression analyses were conducted to examine the association of the potential PA influence factors and PA amount.
About 54.7% of the sample did not fulfill the PA recommendation of 600 MET per week, and there are significant gender differences in PA participation. Factors related to the individual (self-efficacy and value recognition), interpersonal (social support), environmental (workplace and community environment), and polity-level factors (policy advocacy) were found to be significantly associated with Chinese IT professionals' participation in PA.
Numerous correlates from individual-level to political-level factors are all important predictors of PA. Exercise value recognition and self-efficacy accounted for much of the association. Environmental variables may further influence exercise behavior. Therefore, conducting intervention efforts for individual, interpersonal, environmental, and political change of Chinese IT professionals is recommended.
近几十年来，中国的信息技术（IT）人口迅速膨胀，由于缺乏身体活动（PA），他们遭受了严重的健康问题。然而，人们对 PA 不足的影响和解决方案知之甚少。本研究旨在基于社会生态学模型（SEM）探讨 PA 量与潜在影响因素之间的关系，从而为 PA 促进提供依据。
本研究基于 SEM 模型，从个体、人际、环境和政治层面，对来自中国五个城市的 605 名 IT 专业人员进行了日常生活中的 PA 以及潜在 PA 影响因素的调查。采用分层线性回归分析潜在 PA 影响因素与 PA 量的相关性。
约 54.7%的样本没有达到每周 600 个代谢当量的 PA 推荐量，且 PA 参与度存在显著的性别差异。与个体（自我效能和价值认知）、人际（社会支持）、环境（工作场所和社区环境）和政治层面（政策倡导）相关的因素与中国 IT 专业人员参与 PA 显著相关。
从个体层面到政治层面的众多因素都是 PA 的重要预测因素。运动价值认知和自我效能解释了大部分相关性。环境变量可能进一步影响运动行为。因此，建议对中国 IT 专业人员进行个体、人际、环境和政治变化的干预。
