{"doi":"10.1038/s41366-021-00810-9","title":"Temporal relationship between body mass index and uric acid and their joint impact on blood pressure in children and adults: the Bogalusa Heart Study","abstract":"OBJECTIVE: This study aimed to examine the temporal relationship between body mass index (BMI) and uric acid (UA), and their joint effect on blood pressure (BP) in children and adults. METHODS: The longitudinal cohorts for temporal relationship analyses consisted of 564 and 911 subjects examined twice 5-14 years apart from childhood to adulthood. The cross-sectional cohorts for mediation analyses consisted of 3102 children and 3402 nondiabetic adults. Cross-lagged panel analysis models were used to examine the temporal relationship between BMI and UA, and mediation analysis models the mediation effect of UA on the BMI-BP association. RESULTS: After adjusting for age, race, sex and follow-up years in children, and additionally smoking and alcohol drinking in adults, the path coefficients (standardized regression coefficients) from baseline BMI to follow-up UA (0.145 in children and 0.068 in adults) were significant, but the path coefficients from baseline UA to follow-up BMI (0.011 in children and 0.016 in adults) were not. In mediation analyses, indirect effects through UA on the BMI-systolic BP association were estimated at 0.028 (mediation effect = 8.8%) in children and 0.033 (mediation effect = 13.5%) in adults (P < 0.001 for both). Direct effects of BMI on systolic BP (0.289 in children and 0.212 in adults) were significant. The mediation effect parameters did not differ significantly between Blacks and Whites. CONCLUSIONS: Changes in BMI precede alterations in UA, and the BMI-BP association is in part mediated through BMI-related increase in UA both in children and in adults. These findings have implications for addressing mechanisms of obesity hypertension beginning in early life.","journal":"International Journal of Obesity","year":2021,"id":189291,"datarank":0.8545351931077473,"base_score":2.772588722239781,"endowment":2.772588722239781,"self_citation_contribution":0.41588830833596724,"citation_network_contribution":0.43864688477178004,"self_endowment_contribution":0.41588830833596724,"citer_contribution":0.43864688477178004,"corpus_percentile":76.46785797168717,"corpus_rank":3043,"citation_count":15,"citer_count":12,"citers_with_citation_signal":9,"citers_with_endowment":9,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":0.8417,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":8.3333,"fair_percentile":26.47508407214919,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":51186,"name":"Tao Zhang","orcid":"0000-0003-1048-4443","position":1,"is_corresponding":false},{"id":292488,"name":"Shengxu Li","orcid":"0000-0001-9210-7283","position":2,"is_corresponding":false},{"id":268722,"name":"Xuan Wang","orcid":"0000-0002-3528-5785","position":3,"is_corresponding":false},{"id":751418,"name":"Lijun Fan","orcid":"0000-0001-5863-0169","position":4,"is_corresponding":false},{"id":751419,"name":"Yinkun Yan","orcid":"0000-0002-7758-744X","position":5,"is_corresponding":false},{"id":310330,"name":"Lydia Bazzano","orcid":"0000-0002-8958-1352","position":6,"is_corresponding":false},{"id":24759,"name":"Jiang He","orcid":"0000-0002-8286-9652","position":7,"is_corresponding":false},{"id":292489,"name":"Wei Chen","orcid":"0000-0003-1566-7943","position":8,"is_corresponding":false},{"id":751417,"name":"Miaoying Yun","orcid":"0000-0001-9679-878X","position":0,"is_corresponding":true}],"reference_count":35,"raw_metadata":null,"created_at":"2026-07-18T23:49:14.547082Z","pmid":"33824403","pmcid":"PMC8236402","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":27.7778,"fair_a":18.75,"fair_i":0.0,"fair_r":33.3333,"fair_zscore":-1.0337,"fair_rationale":{"fair_score":8.33,"has_llm":true,"taxonomy_version":"fair_taxonomy_v5","dimensions":{"F":{"name":"Findable","score":27.78,"criteria":[{"key":"f_dataset_pid","label":"Persistent identifier for the data","kind":"llm","weight":2.0,"fraction":0.0,"verdict":"no","evidence":null,"grounded":false,"rationale":"No persistent identifier in a recognised scheme is given for this study's own data.

Release the data at publication with no embargo, no registration wall, and no approval step — NIH's zero-embargo public- access rule (NOT-OD-25-101) has already made 'available at publication' the federal baseline for the article; the data should not lag behind it. For clinical / human-subjects data, deposit in dbGaP or the European Genome-phenome Archive (EGA).","Attach a standard, machine-readable open licence to the deposit — CC0 or CC BY, which is what Horizon Europe and most funders expect — and print the licence identifier in the paper. 'Free to use' is not a licence: it grants nothing a reuser's institution can rely on.","Release the data in an open, community-standard format (CSV/TSV, JSON, HDF5, NetCDF, FASTQ, VCF, NIfTI…) instead of — or alongside — any proprietary or instrument-native format, and name the format in the paper. A dataset that needs a €2,000 licence to open is not reusable."],"model":"deepseek/deepseek-v4-flash","agent_version":"fair_agent_v8","fulltext_source":"unpaywall_pdf"},"fair_model":"deepseek/deepseek-v4-flash","fair_agent_version":"fair_agent_v8","fair_fulltext_source":"unpaywall_pdf","fair_has_llm":true,"fair_computed_at":"2026-07-20T12:05:09.934160Z","clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
