Background: Multimorbidity is a common issue in aging societies and is usually associated with dementia in older people. Physical activity (PA) may be a beneficial nonpharmacological strategy for patients with complex health needs. However, insufficient PA is predominant in this population. Thus, there is an evident need to expand the knowledge on potential determinants influencing PA engagement among elderly persons at risk of dementia and multimorbidity. Methods: We used baseline data from the multicenter, cluster-randomized controlled AgeWell.de study. The main aim was to describe PA engagement and identify potential PA determinants in a sample of community-dwelling Germans aged 60−77 years old with an increased risk of dementia and multimorbidity. Results: Of the 1030 included participants, approximately half (51.8%) engaged in PA ≥2 times/week for at least 30 min at baseline. We identified self-efficacy (beta = 0.202, (p < 0.001) and BMI (beta = −0.055, (p < 0.001) as potential PA determinants. Conclusions: The identified determinants, self-efficacy, and BMI are consistent with those reported in the literature. Specific knowledge on PA determinants and stages of change in persons with risk of dementia and multimorbidity might guide the development of effective future prevention measures and health services tailored to this population.

多病共存是老龄化社会的一个常见问题，通常与老年人的痴呆有关。身体活动（PA）可能是患有复杂健康需求的患者的有益的非药物策略。然而，该人群中普遍存在身体活动不足的问题。因此，显然需要扩大对有痴呆和多病共存风险的老年人参与身体活动的潜在决定因素的知识。方法：我们使用多中心、聚类随机对照 AgeWell.de 研究的基线数据。主要目的是描述社区居住的德国老年人的身体活动参与情况，并确定潜在的身体活动决定因素，这些老年人年龄在 60-77 岁之间，有较高的痴呆和多病共存风险。结果：在 1030 名纳入的参与者中，约有一半（51.8%）在基线时至少每周进行 2 次、每次至少 30 分钟的身体活动。我们确定了自我效能感（β=0.202，p<0.001）和 BMI（β=-0.055，p<0.001）是潜在的身体活动决定因素。结论：确定的决定因素，即自我效能感和 BMI，与文献中报道的一致。在有痴呆和多病共存风险的人群中，对身体活动决定因素和改变阶段的具体了解，可能有助于制定针对该人群的有效未来预防措施和卫生服务。试验注册：德国临床试验注册（参考编号：DRKS00013555）。
