Limited research has looked at the current situation of PA and SB during this pandemic among children and adolescents with intellectual disabilities (ID). This study investigated the situations about PA and SB among school\u2010aged children and adolescents with ID on China's mainland during the COVID\u201019 outbreak.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In total, 837 parents of children and adolescents (ages 6\u201318\u00a0years) with ID from 15 special education schools of Shandong Province in China were recruited through convenience sampling in the study. Parents reported PA and SB among children and adolescents with ID through the Children's Leisure Activities Study Survey\u2010Chinese version (CLASS\u2010C) online questionnaires.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>From parents' reports, Chinese children and adolescents with ID during the COVID\u201019 pandemic participated in approximately 10\u00a0min of moderate\u2010to\u2010vigorous physical activity, and engaged in approximately 530\u00a0min of SB every day. Meanwhile, only 17.4% of children and adolescents with ID were able to achieve the recommendation of 60\u00a0min of daily moderate\u2010to\u2010vigorous physical activity and 76.1% of children and adolescents with ID spent more than 2\u00a0h on SB per day. Additionally, the problems of decrease PA and excessive SB were more prominent in older adolescents with ID compared with younger children with ID.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In China, the low level of PA and high level of SB is particularly evident in children and adolescents with ID during the outbreak of COVID\u201019. The great majority of children and adolescents with ID did not meet the recommended amount of PA while undergoing excessive SB under the long\u2010term home quarantine environment. Therefore, immediate attention and great effort should be made to deal with this severe situation among this vulnerable population in the mainland of China.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jir.12898","type":"journal-article","created":{"date-parts":[[2021,11,3]],"date-time":"2021-11-03T12:21:27Z","timestamp":1635942087000},"page":"913-923","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Physical activity and sedentary behaviour among children and adolescents with intellectual disabilities during the COVID\u201019 lockdown in China"],"prefix":"10.1111","volume":"66","author":[{"given":"Y.
