{"doi":"10.17756/jocd.2020-039","title":"Psychosocial Predictors of Weight Loss and Quality of Life at 1 Year Post-Bariatric Surgery: A Cohort Study","abstract":"Background: Psychosocial factors, identified in pre-bariatric surgery evaluation, may affect surgical outcomes, as well as defer surgery, making it important to identify psychosocial predictors of surgery outcomes. Methods: Baseline depressive and social anxiety symptom scores were analyzed as predictors of post-surgical weight loss (WL) and quality of life (QOL) following Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (AGB). Eighty-nine (82F, 7M) participants underwent surgery and completed depression, anxiety and QOL questionnaires 3-weeks pre-surgery and 1-year post-surgery. Results: Depressive scores and QOL scores improved post-surgery (P < 0.001), whereas social anxiety scores did not (P = 0.20). Baseline depressive (P = 0.90) and social anxiety (P = 0.20) scores did not predict % weight loss (WL) at 1 year, but higher baseline depressive (P = 0.04) and social anxiety (P = 0.005) scores predicted lower post-surgical QOL at 1 year. RYGB showed greater improvement in %WL (P < 0.001) than AGB, but no difference between the groups in QOL (P = 0.10). Improvement in QOL correlated with %WL (P < 0.001), whereas improvement in depressive scores did not correlate with %WL (P = 0.70) but did correlate with improvement in QOL (P = 0.01). Conclusions: Baseline depressive and social anxiety scores predicted QOL but not %WL. Depressive and QOL scores improved post-surgery, but social anxiety scores did not. The findings suggest that patients who present with depressive or social anxiety symptoms pre-surgery perhaps should not be deferred; however, more studies are needed to confirm this. Patients with pre-operative social anxiety symptoms may benefit from counseling.","journal":"Journal of Obesity and Chronic Diseases","year":2020,"id":108873,"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":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9569,"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":521442,"name":"Dorina Kordunova","orcid":null,"position":1,"is_corresponding":false},{"id":521443,"name":"Chungwon Kim","orcid":null,"position":2,"is_corresponding":false},{"id":521444,"name":"Laura Kolbe","orcid":null,"position":3,"is_corresponding":false},{"id":520768,"name":"Allan Geliebter","orcid":"0000-0002-2747-4201","position":4,"is_corresponding":false},{"id":521441,"name":"Chia-Hao Hsu","orcid":null,"position":0,"is_corresponding":true}],"reference_count":43,"raw_metadata":null,"created_at":"2026-07-18T23:12:46.854423Z","pmid":"36156871","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":[]}
