Previous studies suggest social support is associated with musculoskeletal health in later life. We explored this relationship further in community-dwelling older adults, by considering associations between different aspects of social support and musculoskeletal health in community-dwelling adults. Participants from the Hertfordshire Cohort Study reported level of confiding/emotional, practical, and negative support using the Close Persons Questionnaire. Muscle strength was measured by grip strength dynamometry, and physical capability by timed up-and-go, chair rises, and walking speed tests. Bone mineral density (BMD) was assessed using dual-energy x-ray absorptiometry. Linear regression, adjusted for age, sex, body mass index (BMI), alcohol, smoking, physical activity, social class, and diet, was used for analysis. 1842 men and women (mean age 65.7 years) participated. Low emotional support correlated with weaker grip strength and poorer physical capability tests, although estimates were not robust to adjustment for confounders. Low practical support was linked to shorter timed up-and-go (β - 0.171, 95%CI - 0.319, - 0.024) and walking speed times (β - 0.157, 95%CI - 0.306, - 0.007), following adjustment for confounders. Negative support (i.e. the perceived inadequacy of the support received) was associated with lower grip strength (β - 0.145, 95%CI - 0.223, - 0.067) and slower walking speeds (β 0.159, 95%CI 0.004, 0.314). No social support exposures were associated with BMD. Different types of social support are linked to various measures of musculoskeletal health in older adults. Limited requirement for practical support correlated with better physical capability, while negative support correlated with poorer outcomes. No social support measure was associated with BMD.
先前的研究表明，社会支持与晚年的肌肉骨骼健康有关。我们通过研究社区居住的老年人中社会支持的不同方面与肌肉骨骼健康之间的关联，进一步探讨了这种关系。来自赫特福德郡队列研究的参与者使用亲密关系问卷报告了倾诉/情感、实际和负面支持的程度。肌肉力量通过握力计测量，身体能力通过计时起立行走、椅子起立和步行速度测试来评估。使用双能X线吸收法评估骨密度（BMD）。采用线性回归分析，并对年龄、性别、体重指数（BMI）、饮酒、吸烟、体育活动、社会阶层和饮食进行了调整。共有1842名男性和女性（平均年龄65.7岁）参与。低情感支持与较弱的握力和较差的身体能力测试相关，尽管在对混杂因素进行调整后，估计结果并不稳健。在对混杂因素进行调整后，低实际支持与更短的计时起立行走时间（β -0.171，95%CI -0.319，-0.024）和步行速度时间（β -0.157，95%CI -0.306，-0.007）相关。负面支持（即感觉到所获得的支持不足）与较低的握力（β -0.145，95%CI -0.223，-0.067）和较慢的步行速度（β 0.159，95%CI 0.004，0.314）相关。没有社会支持暴露与骨密度相关。不同类型的社会支持与老年人肌肉骨骼健康的各种指标相关。对实际支持的需求有限与更好的身体能力相关，而负面支持与较差的结果相关。没有社会支持指标与骨密度相关。
