Although there is a lack of knowledge about the health status and care management of the oldest people, a better understanding of the natural course of life of people with polyhandicap/PIMD would consequently allow the optimisation of preventive and curative care management strategies. Few robust data on mortality and life expectancy have been documented for this population in France.

The people included in the first wave of the cohort (2015–2016) were eligible for the present study. Vital status on 1 January 2022 (censoring date) was collected in two ways: (1) spontaneous reporting by the participating centre to the coordinating team and (2) systematic checking on the French national death platform. According to the vital status, survival was calculated in years from the date of birth to the date of death or from the date of birth to the censoring date.

All coefficients of variation for gait parameters were higher in participants with ID. Additionally, changes in gait were observed in both groups during the DT condition compared with the single-task condition. These changes were larger for participants with ID in step length, double support time and gait speed (<i>P</i> &lt; 0.001), resulting in a higher DTC in these variables in the ID group (<i>P</i> &lt; 0.01).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Both groups reduced gait performance in the DT condition. However, greater gait variability occurred in the ID group. In addition, DTC was higher for the ID group in all variables analysed. Therefore, people with ID show worse gait performance during a DT than people WID.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16163,"journal":{"name":"Journal of Intellectual Disability Research","volume":"68 6","pages":"610-619"},"PeriodicalIF":3.6,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jir.13134","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140158334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
