Age related decline of intrinsic capacity (IC) is the core of the functional ability and risk factor of adverse outcomes such as disability, hospitalization, and mortality. However, the relationship between sleep disturbance and IC decline are largely unknown. We conducted a longitudinal study and used data of 1514 community elders from the aging arm of the Rugao Longevity and Ageing Study. We found that poor sleep quality is cross-sectional associated with an increased risk of lower IC. In longitudinal analysis, sleep disturbances were inversely associated with composite IC score changes after adjusting for confounders (PSQI>5 vs. PSQI≤5: mean difference [-0.23], P = 0.0005), suggesting that poor sleep quality was associated with a decline in IC during the follow-up period. In conclusion, sleep disturbances were associated with worse IC changes. The results suggest that improving sleep health may help prevent IC decline and hence decreasing the burden of geriatric nursing practice.
与年龄相关的内在能力（IC）下降是功能能力的核心，也是残疾、住院和死亡等不良后果的风险因素。然而，睡眠障碍与IC下降之间的关系在很大程度上尚不清楚。我们进行了一项纵向研究，使用了如皋长寿与衰老研究中1514名社区老年人的衰老组数据。我们发现，睡眠质量差与IC降低风险增加呈横断面相关。在纵向分析中，调整混杂因素后，睡眠障碍与综合IC评分变化呈负相关（PSQI>5与PSQI≤5：平均差异[-0.23]，P = 0.0005），表明睡眠质量差与随访期间IC下降有关。总之，睡眠障碍与更差的IC变化有关。结果表明，改善睡眠健康可能有助于预防IC下降，从而减轻老年护理实践的负担。
