However, it is uncertain if these findings apply to other populations, particularly those without diabetes. Additionally, the influence of diabetes on these associations needs further exploration, and the link between SO and rapid kidney function decline (RKFD) remains unestablished. Evidence regarding the effects of SO on incident CKD and RKFD in the Chinese population is limited, highlighting the necessity for this study to fill these gaps in knowledge. What this study adds\u00a0 This study is the first to prospectively explore the association of SO with incident CKD and RKFD in middle-aged and older Chinese adults. We identified SO as a significant risk factor for increased incidence of both CKD and RKFD. These findings expand the understanding of the impact of SO beyond individuals with diabetes mellitus, indicating that SO is a universal risk factor for adverse kidney outcomes in aging populations, irrespective of demographic and health characteristics. How this study might affect research, practice, or policy\u00a0 This study identifies SO as an independent risk factor for incident CKD and RKFD in middle-aged and older Chinese adults. The findings suggest that SO is a modifiable risk factor for kidney health, underscoring the necessity for timely interventions to prevent adverse kidney outcomes. Given the rising prevalence of SO and kidney disease in aging populations worldwide, these results highlight the importance of incorporating SO management into public health and clinical strategies. Questions pending answer\u00a0 What role do specific lifestyle factors (e.g. diet, physical activity) play in mitigating or exacerbating kidney function decline in individuals with SO? Are there genetic markers that predispose individuals with SO to a higher risk of incident CKD and RKFD? What are the underlying molecular mechanisms linking SO to incident CKD and RKFD?<\/jats:p>\n
