{"doi":"10.1353/obs.2020.0013","title":"The START study: An evaluation to study the impact of a natural experiment in high school start times on adolescent weight and related behaviors","abstract":"BACKGROUND: Research has shown that early high school start times, which are asynchronous with adolescent biology, are one of the most significant obstacles to youth being able to net sufficient sleep. Given that adolescence is a critical period that sets the stage for long-term obesity risk behavior patterns, there is an need to understand the obesity-related implications of increased sleep as a result of intervention and policy changes. METHODS: grade students (class of 2019) in the five schools. The sample was 87.7% white, 12.8% reported qualifying for free/reduced price lunch (a measure of lower socio-economic status), and the mean age was 15.2 (SD=0.35) years. DISCUSSION: The products of this research will clarify causal connections between sleep and obesity among adolescents as well as provide evidence for whether a school start time policy can minimize unhealthy weight gain.","journal":"Observational Studies","year":2020,"id":83230,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":12,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9552,"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":428482,"name":"Kyla Wahlstrom","orcid":"0000-0003-4605-2036","position":1,"is_corresponding":false},{"id":422535,"name":"Melissa N.
