{"doi":"10.1002/oby.22801","title":"Overweight and Obesity Impair Academic Performance in Adolescence: A National Cohort Study of 10,279 Adolescents in China","abstract":"OBJECTIVE: This study aimed to examine the associations of overweight and obesity (ov/ob) and changes in weight status with academic performance among Chinese adolescents. METHODS: Self-reported weight and height were collected from adolescents (n = 10,279) each year from seventh grade (baseline, 2013-2014) to ninth grade (2015-2016). Academic performance included standardized scores on math, Chinese, and English examinations and responses to a school-life experience scale. RESULTS: All adolescents with ov/ob had lower academic performance than their counterparts without overweight (β = -0.46 to -0.08; P < 0.05), except for school-life experience for boys. All adolescents with obesity had lower academic performance than their counterparts without obesity (β = -0.46 to -0.17; P < 0.01), except for English test scores for boys. Changes in weight status between grades 7 and 9 impacted academic performance at grade 9. Adolescents with ov/ob throughout grades 7 to 9 and those who developed ov/ob from normal weight had lower test scores (β = -0.80 to -0.25; P < 0.05) than those who maintained normal weight. Those who developed ov/ob after having normal weight had poorer school-life experiences (β = -0.55 to -0.25; P < 0.05). CONCLUSIONS: Ov/ob and maintaining and developing ov/ob had adverse academic impacts on adolescents. Relevant stakeholders should consider detrimental impacts of obesity on academic outcomes.","journal":"Obesity","year":2020,"id":101527,"datarank":1.1183582446482223,"base_score":3.332204510175204,"endowment":3.332204510175204,"self_citation_contribution":0.49983067652628066,"citation_network_contribution":0.6185275681219418,"self_endowment_contribution":0.49983067652628066,"citer_contribution":0.6185275681219418,"corpus_percentile":81.75137309507232,"corpus_rank":2360,"citation_count":27,"citer_count":27,"citers_with_citation_signal":20,"citers_with_endowment":20,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":0.5142,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"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":371428,"name":"Liwang Gao","orcid":"0000-0003-0908-3239","position":1,"is_corresponding":false},{"id":460970,"name":"Dorothy T.
