This study aims to examine the relative independent relationship between suicide ideation and subjective sleep quality, sleep hygiene, and insomnia symptoms in undergraduate students in China. This population-based study included 2379 undergraduate students aged 18\u201326, randomly recruited from three public universities in Shanghai. The participants completed four questionnaires: the Pittsburgh Sleep Quality Index; Sleep Hygiene Practice Scale; Insomnia Severity Index; and the Symptom Checklist 90 (specifically the depression and anxiety dimensions and Q15-suicide ideation). The results of Spearman\u2019s correlation analysis indicate that poor sleep quality, short sleep duration, poor sleep hygiene, and insomnia symptoms were all associated with suicidal ideation in undergraduate students. However, according to the results of the hierarchical linear regression, no experience of sharing a bedroom at home, poor relationship with roommates, short sleep duration, sleep medicine use, and good daytime function were related to suicidal ideation, after controlling for the symptoms of depression and anxiety, which may be important in the identification of suicidal ideation. Sleep problems are highly discoverable and modifiable, and have a low sense of shame, therefore, sleep interventions for individuals with suicidal ideation and poor sleep quality may be an efficient and effective approach to suicide prevention.<\/jats:p>","DOI":"10.3390\/ijerph192315433","type":"journal-article","created":{"date-parts":[[2022,11,22]],"date-time":"2022-11-22T08:25:28Z","timestamp":1669105528000},"page":"15433","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Association between Sleep and Suicidal Ideation in Chinese Undergraduate Students"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6310-2352","authenticated-orcid":false,"given":"Ran","family":"Wu","sequence":"first","affiliation":[{"name":"Counseling and Psychological Services Center, East China Normal University, Shanghai 200062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun-Ying","family":"Wang","sequence":"additional","affiliation":[{"name":"Counseling and Psychological Services Center, East China Normal University, Shanghai 200062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Wang","sequence":"additional","affiliation":[{"name":"Centre for Psychological Health Education and Counseling, Shanghai University of Medicine & Health Sciences, Shanghai 201318, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Jing","family":"Wang","sequence":"additional","affiliation":[{"name":"Counseling and Psychological Services Center, East China Normal University, Shanghai 200062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Zhu","sequence":"additional","affiliation":[{"name":"Counseling and Psychological Services Center, East China Normal University, Shanghai 200062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guang-Hai","family":"Wang","sequence":"additional","affiliation":[{"name":"Pediatric Translational Medicine Institution, Shanghai Children\u2019s Medical Center, School of Medicine, Shanghai Jiao Tong University, Shanghai 200127, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun-Lei","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Stress Medicine, Faculty of Psychology, Second Military Medical University, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,22]]},"reference":[{"key":"ref_1","unstructured":"WHO (2022, October 01).
