The relationship between early childhood co-sleeping and adolescent behavior problems remains uncertain. We aim to identify whether early childhood co-sleeping can predict behavior problems in preadolescence. PARTICIPANTS: A cohort of 1,656 Chinese preschool children were followed up in adolescence. METHODS: Prospective cohort study design involving two waves of data collection from the China Jintan Cohort (1,656 children aged 3-5 years). Co-sleeping history was collected at 3-5-years-old via parent-reported questionnaire at wave I data collection. Behavior problems were measured twice in childhood and preadolescence, respectively. Adolescent behavior problems were measured by integrating data from self-report, parent-report and teacher-report using the Achenbach System of Empirically Based Assessment. Predictions were assessed using the general linear model with mixed effects on the inverse probability weight propensity-matched sample. RESULTS: 1,656 children comprising 55.6% boys aged 4.9 ± 0.6 were initially enrolled in the first wave of data collection. In the second wave of data collection, 1,274 children were 10.99 ± 0.74 (76.9%) aged 10-13 years were retained. Early childhood co-sleeping is significantly associated with increased behavior problems in childhood (Odds Ratio [OR] 1.22-2.06, ps<0.03) and preadolescence (OR 1.40-2.27, ps<0.02). Moreover, co-sleeping history significantly predicted multiscale increase in internal (OR 1.63-2.61, ps<0.02) and external behavior problems in adolescence. CONCLUSIONS: Early childhood co-sleeping is associated with multiple behavioral problems reported by parents, teachers, and children themselves. Early childhood co-sleeping predicts preadolescent internalizing and externalizing behavior after controlling for baseline behavior problems.","journal":"Behavioral Sleep Medicine","year":2020,"id":87715,"datarank":0.37273599746820013,"base_score":2.4849066497880004,"endowment":2.4849066497880004,"self_citation_contribution":0.37273599746820013,"citation_network_contribution":0.0,"self_endowment_contribution":0.37273599746820013,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":11,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.637,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":332165,"name":"Ying Dai","orcid":"0000-0001-5375-2693","position":1,"is_corresponding":false},{"id":445600,"name":"Xianchen Liu","orcid":"0000-0003-0411-1050","position":2,"is_corresponding":false},{"id":445601,"name":"Jianghong Liu","orcid":"0000-0003-2528-9931","position":3,"is_corresponding":false},{"id":445599,"name":"Zehang Chen","orcid":"0009-0008-0880-2151","position":0,"is_corresponding":true}],"reference_count":53,"raw_metadata":{"citation_network_status":"fetched"},"created_at":"2026-07-18T22:00:29.831859Z","pmid":"32946284","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
