Psychological outcomes after surgery are clinically important.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This prospective, non-interventional, longitudinal cohort enrolled adults scheduled for bariatric surgery at King Abdulaziz University Hospital (Jeddah, Saudi Arabia). The participants completed two online questionnaires: one pre-and one post-surgery (planned at approximately 6 months). Depression and anxiety symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7). Positive screening was defined as PHQ-9 \u226510 and GAD-7 \u226510. Weight was self-reported using the questionnaires. Post-surgical complications were self-reported in the post-surgery questionnaire as \u2018yes\/no\u2019 items. Pre- and post-surgery scores were compared using the paired t-test. Sensitivity analysis was assessed using the Wilcoxon signed-rank test. Proportions that screened positive were compared using the Z-test. Univariate linear regression was used to assess the association between symptom changes and demographic, clinical, and surgical factors. Analyses were conducted using Stata\/AC v18.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Twenty-seven participants completed the pre-surgery questionnaire, and 23 completed the post-surgery questionnaire. The matched analyses included 23 participants. The mean (SD) age was 33.6 (10.4) years, and 11 (47.8%) were female. Although follow-up was planned at approximately 6 months, the completion time varied (mean 359.5 [273.5] days; median 224; range 84\u2013906). The mean (SD) GAD-7 decreased from 6.0 (5.9) to 5.2 (5.5) (p=0.565), while the mean (SD) PHQ-9 decreased from 7.5 (7.3) to 5.9 (6.4) (p=0.430). The proportion screening positive decreased from 26.1% to 17.4% for GAD-7 (p=0.475), and from 26.1% to 13.0% for PHQ-9 (p=0.265). In the univariate models, post-surgical complications were associated with worse anxiety and depression trajectories, while prior anxiety diagnosis was associated with greater improvement in anxiety symptoms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this cohort, the average depression and anxiety scores declined after bariatric surgery, although the overall changes were not statistically significant. Self-reported post-surgical complications were consistently associated with worse psychological outcomes. Our findings support the need for integrated psychiatric follow-ups during the bariatric surgical evaluations, before surgery and after surgery, particularly in patients with reported complications.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyt.2026.1828215","type":"journal-article","created":{"date-parts":[[2026,6,16]],"date-time":"2026-06-16T15:50:11Z","timestamp":1781625011000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Depression and anxiety before and after bariatric surgery: a longitudinal cohort study at King Abdulaziz University Hospital, Jeddah, Saudi Arabia"],"prefix":"10.3389","volume":"17","author":[{"given":"Naseem Abdulmohi","family":"Alhujaili","sequence":"first","affiliation":[{"name":"Department of Medicine, Division of Psychiatry, Faculty of Medicine, King Abdulaziz University","place":["Rabigh, Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salhah Saleh","family":"Alsulami","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine, King Abdulaziz University","place":["Rabigh, Saudi Arabia"]},{"name":"Department of Medicine, King Abdulaziz University Hospital, King Abdulaziz University","place":["Jeddah, Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wesam Ayed","family":"Almutairi","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine, King Abdulaziz University","place":["Rabigh, Saudi Arabia"]},{"name":"Department of Medicine, King Abdulaziz University Hospital, King Abdulaziz University","place":["Jeddah, Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eman","family":"Al-khalawi","sequence":"additional","affiliation":[{"name":"Department of Family and Community Medicine, Faculty of Medicine, King Abdulaziz University","place":["Rabigh, Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alaa","family":"Sabbahi","sequence":"additional","affiliation":[{"name":"Department of Anesthesia and Critical Care, Faculty of Medicine, King Abdulaziz University","place":["Jeddah, Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulaziz Abdullah","family":"Alghamdi","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine, King Abdulaziz University","place":["Rabigh, Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Murad","family":"Aljiffry","sequence":"additional","affiliation":[{"name":"Department of Surgery, Faculty of Medicine, King Abdulaziz University","place":["Jeddah, Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,6,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0094433","article-title":"Association between obesity and selected morbidities: a study of BRICS countries","volume":"9","author":"Shukla","year":"2014","journal-title":"PloS One"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1080\/13548506.2014.959531","article-title":"Pre-operative history of depression and cognitive changes in bariatric surgery patients","volume":"20","author":"Alosco","year":"2015","journal-title":"Psychol Health Med"},{"key":"B3","doi-asserted-by":"publisher","first-page":"19","DOI":"10.3810\/pgm.2003.12.1544","article-title":"Evaluation of obesity: who are the obese","volume":"114","author":"Bray","year":"2003","journal-title":"Postgraduate Med"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1038\/ijo.2008.11","article-title":"Accuracy of body mass index in diagnosing obesity in the adult general population","volume":"32","author":"Romero-Corral","year":"2008","journal-title":"Int J Obes"},{"key":"B5","doi-asserted-by":"publisher","first-page":"51S","DOI":"10.1002\/j.1550-8528.1998.tb00690.x","article-title":"on the Identification, Evaluation, and Treatment of Overweight and Obesity in Adults.
