Healthy Life Centers (HLCs) have been established throughout Norway to support lifestyle changes and promote physical and mental health. We conducted a 12-month observational study among participants in an HLC that aimed to improve physical activity (PA) and dietary behaviors, and this study examined predictors of completion, and changes in psychological variables, lifestyle behaviors, and physical health indicators. The participants (N = 120, 71% female, mean age = 44 years) reported symptoms of psychological distress (77%) and were obese (77%). No baseline characteristics were found to be consistent predictors of completion (42%). Completers had significant improvements in autonomous motivation for PA ( = 0.89), perceived competence for PA ( = 1.64) and diet ( = 0.66), psychological distress ( = 0.71), fruit intake ( = 0.64), vegetable intake ( = 0.38), BMI among all participants ( = 0.21) and obese participants ( = 0.34), body fat percentage among all participants ( = 0.22) and obese participants ( = 0.33), and lower body strength ( = 0.91). Fat-free mass and all forms of PA remained unchanged from baseline to 12 months. Hence, there were indications of improvement among completers on psychological variables, lifestyle behaviors, and physical health indicators. The low rate of completion was a concern, and the unchanged levels of PA reflect an important area of focus for future interventions in the context of HLCs.
健康生活中心（HLC）已在挪威各地设立，以支持生活方式的改变，促进身心健康。我们对 HLC 的参与者进行了为期 12 个月的观察性研究，旨在改善身体活动（PA）和饮食行为，并研究了完成情况的预测因素，以及心理变量、生活方式行为和身体健康指标的变化。参与者（N=120，71%为女性，平均年龄为 44 岁）报告有心理困扰症状（77%）和肥胖（77%）。没有发现基线特征是完成情况的一致预测因素（42%）。完成者在 PA 的自主动机（=0.89）、PA 和饮食的感知能力（=1.64）、心理困扰（=0.71）、水果摄入量（=0.64）、蔬菜摄入量（=0.38）、所有参与者的 BMI（=0.21）和肥胖参与者的 BMI（=0.34）、所有参与者的体脂肪百分比（=0.22）和肥胖参与者的体脂肪百分比（=0.33）以及下肢力量（=0.91）方面均有显著改善。从基线到 12 个月，无脂肪质量和所有形式的 PA 均保持不变。因此，完成者在心理变量、生活方式行为和身体健康指标方面有改善的迹象。完成率低是一个令人关注的问题，PA 水平不变反映了 HLC 背景下未来干预的一个重要关注领域。
