摘　　要：为阐明居住安排对农村老年人骨骼肌健康的影响机制,基于中国营养与健康调查(CHNS)数据,重点考察了居住安排与农村老年人骨骼肌健康之间的关系,以及膳食质量在二者关系中的中介作用。研究发现:(1)与配偶同住(无子女)有助于老年人的骨骼肌健康,而独居和与子女同住(无配偶)不利于老年人骨骼肌健康。(2)异质性检验结果表明,与配偶同住(无子女)对低龄老年人骨骼肌健康的提升效果更显著,对高龄老年人并无显著影响。(3)膳食质量能够在居住安排与老年人骨骼肌健康的关系中起中介作用,与配偶同住(无子女)抑制了老年人的膳食失衡,进而促进老年人骨骼肌健康。To elucidate the influence mechanism of living arrangements on the skeletal muscle health of rural older adults,based on data from the China Health and Nutrition Survey(CHNS),this study focuses on examining the relationship between living arrangements and skeletal muscle health of rural older adults,as well as the mediating role of dietary quality in the relationship between the two.Research has found that:(1)Living with spouse(without children)are beneficial for the skeletal muscle health of older adults,while living alone or with children(without a spouse)is not conducive to their skeletal muscle health.(2)The heterogeneity test results indicate that living with spouse(without children)have a more significant effect on improving skeletal muscle health in the young old adults,but have no significant effect on the oldest-old.(3)Dietary quality can play a mediating role in the relationship between living arrangements and skeletal muscle health in older adults.Living with spouse(without children)suppress dietary imbalance in older people,thereby promoting skeletal muscle health in older adults.
