Cox proportional hazards models were used to evaluate the associations of SO with incident CLD and PEF-related outcomes. Inverse probability of treatment weighting (IPTW) was applied to balance baseline characteristics between participants with and without SO. Random forest-based analyses were conducted as supplementary analyses to support the main findings.ResultsA total of 3,572 participants from CHARLS and 2,436 from ELSA without CLD at baseline were included in the CLD analysis. During follow-up, SO was significantly associated with a higher risk of incident CLD. In the CHARLS cohort, SO was positively associated with CLD risk after full adjustment (Model 3: HR = 1.50, P = 0.003). Consistent results were observed in the ELSA cohort after adjustment for ethnicity (Model 1: HR = 2.19, P = 0.006). Associations between SO and PEF were not consistently observed across cohorts.ConclusionsSarcopenic obesity was associated with an increased risk of chronic lung disease among older adults, suggesting that SO may be a potential body composition-related marker of respiratory risk.

This narrative review addresses the challenges and potential solutions for reducing digital exclusion for people living with CRD. Although sparse, the available evidence suggests that digital exclusion leads to poorer health outcomes in people living with CRD. The barriers that lead to digital exclusion intersect at many different levels and include socioeconomic, demographic, geographical, digital literacy, design/accessibility and psychosocial factors. Solutions to mitigate digital exclusion in people with CRD need to operate at multiple scales with cross-sectoral collaboration, and range from ensuring access to digital tools via large national mobile/broadband infrastructure developments to ensuring DHTs for patient use are designed inclusively and frontline healthcare staff are trained to help patients engage with the tools. Currently, there is a real risk that deploying digital health interventions for CRD care may widen the digital divide and deepen health inequities. To deliver on the digital health promise, all relevant stakeholders need to be focussed on ensuring that the presence of digital exclusion is well monitored and underserved communities such as CRDs are not systematically excluded from implementation and evaluation efforts.</p>","PeriodicalId":10217,"journal":{"name":"Chronic Respiratory Disease","volume":"23 ","pages":"14799731261441307"},"PeriodicalIF":2.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13051112/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147608387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional approaches often rely on episodic clinical assessments and patient-reported symptoms, which fail to capture the dynamic nature of respiratory health. The integration of wearable technology offers a transformative solution, enabling continuous, real-time monitoring of physiological and behavioural parameters. This review explores the evolving role of wearable devices, including activity trackers, smartwatches, spirometers, and biosensors, in modernising chronic respiratory disease management. Evidence across disease domains demonstrates that wearables can enhance physical activity, predict exacerbations, support remote rehabilitation, and facilitate personalised care. In Chronic obstructive pulmonary disease, step counters and biometric sensors have shown improvements in activity levels and early exacerbation detection. Asthma care benefits from AI-driven platforms that integrate environmental and physiological data to optimise treatment. For Interstitial lung disease and Cystic fibrosis, home spirometry and sweat biomarker monitoring empower patients and improve disease tracking. In Pulmonary hypertension, wearables provide insights into activity and sleep patterns, complementing traditional assessments. Despite promising outcomes, barriers remain. Technical limitations, data reliability, digital literacy, privacy concerns, and integration into clinical workflows hinder widespread adoption. Economic and equity considerations further challenge scalability, particularly in low-resource settings. Looking forward, the convergence of multimodal sensing, AI analytics, and digital therapeutics will enable proactive, personalised, and equitable respiratory care. Addressing validation, interoperability, and ethical governance will be critical to realising the full potential of wearable technology in CRD management.</p>","PeriodicalId":10217,"journal":{"name":"Chronic Respiratory Disease","volume":"23 ","pages":"14799731261454686"},"PeriodicalIF":2.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13191128/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147971050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
