This study evaluates long-term changes in physical activity and its associations with various predictors after a behavior change program at the Norwegian Healthy Life Centers.
Physical activity is recommended and is part of public health strategies to prevent noncommunicable diseases.
This longitudinal cohort, based on a controlled randomized trial, studies a population of 116 Healthy Life Center participants in South-Western Norway who wore SenseWear Armbands to measure time spent in moderate to vigorous physical activity and sedentary time based on metabolic equivalents. The measurements were obtained at baseline, immediately post-intervention, and 24 months after baseline. Linear mixed model analyses were performed to assess predictors for change in physical activity and sedentary time.
High physical activity levels at baseline were maintained during the 24-month study period. Young, male participants with good self-rated health, utilizing local PA facilities were most active, and young participants utilizing local facilities were also less sedentary. The participants with higher levels of education were less active initially but caught up with the difference during follow-up. A high degree of controlled regulation, characterized by bad conscience and external pressure, predicted more sedentary behavior and a trend toward being less physically active. Autonomous motivation was associated with less time spent on sedentary behaviors. People with high self-efficacy for physical activity were more sedentary initially but showed a reduction in their sedentary behavior.The study supports the importance of attending local training facilities and adopting motivation for behavioral change that is not based on guilt and external rewards. Interventions aimed at improving physical activity among people at risk for noncommunicable diseases benefit from habitual use of local training facilities, strengthening their self-perceived health and the development of internalized motivation. However, it has not been shown to mitigate social health disparities.
本研究评估了挪威健康生活中心行为改变计划后，体力活动的长期变化及其与各种预测因素的关系。
体力活动是预防非传染性疾病的推荐内容，也是公共卫生策略的一部分。
本纵向队列研究基于一项对照随机试验，研究了挪威西南部 116 名健康生活中心参与者的人群，他们佩戴 SenseWear 臂带，根据代谢当量测量中度到剧烈体力活动和久坐时间。测量结果在基线、干预后即刻和基线后 24 个月获得。线性混合模型分析用于评估体力活动和久坐时间变化的预测因素。
高基线体力活动水平在 24 个月的研究期间得以维持。年轻、男性、自我报告健康状况良好、利用当地 PA 设施的参与者最为活跃，年轻参与者利用当地设施也较少久坐。教育程度较高的参与者最初活动水平较低，但在随访期间赶上了差距。高度的控制调节，表现为内疚感和外部压力，预测了更多的久坐行为和体力活动减少的趋势。自主动机与较少的久坐行为有关。最初体力活动自我效能感较高的人久坐时间较多，但随后减少了久坐行为。该研究支持关注当地培训设施和采用基于内疚感和外部奖励的行为改变动机的重要性。针对非传染性疾病高危人群的提高体力活动的干预措施受益于习惯性使用当地培训设施，增强了他们的自我感知健康和内在动机的发展。然而，它并没有显示出减轻社会健康差距的作用。
