身体机能和认知能力对幸福都很重要，尤其是在老年。握力通常被认为是总体活力的指标，因此可以预测认知功能。很少有纵向研究探讨了握力和认知之间的关系，特别是在特定的认知能力已经targeted.Participants（n = 708，年龄范围：40-86岁的基线）来自人口为基础的纵向瑞典收养/双胞胎老化研究。我们在20年中使用了6个波的纵向随访。对于分析，我们使用潜在的增长模型，其中潜在的增长轨迹拟合的认知特征（言语能力，空间能力，处理速度和记忆）或握力值和每一个，分别被视为随时间变化的协变量的其他trait.Results支持纵向影响的握力对认知功能的变化。65岁以后，握力与4种认知能力的变化相关，从65岁左右开始，握力与认知能力的关系比较稳定。起始期表明，这种关联可能是由于生活方式的改变，如退休，或加速老化过程。
Both physical functioning and cognitive abilities are important for well-being, not least in old age. Grip strength is often considered an indicator of general vitality and, as such, may predict cognitive functioning. Few longitudinal studies have examined the relationship between grip strength and cognition, especially where specific cognitive abilities have been targeted.Participants (n = 708, age range: 40-86 years at baseline) came from the population-based longitudinal Swedish Adoption/Twin Study of Aging. We used a longitudinal follow-up of 6 waves during 20 years. For the analyses, we used latent growth modeling, where latent growth trajectories were fitted to the cognitive traits (verbal ability, spatial ability, processing speed, and memory) or to the grip strength values and each, respectively, treated as time-varying covariates of the other trait.Results supported a longitudinal influence of grip strength on changes in cognitive function. Grip strength performance was associated with change in the 4 cognitive abilities after age 65 years.A rather stable connection was found between grip strength and cognitive abilities starting around 65 years of age. The starting period suggests that the association may be due to lifestyle changes, such as retirement, or to acceleration of the aging processes.
