Linear regression was used to separately compare 5‐year changes in depression and anxiety symptoms (by Hospital Anxiety and Depression Scale) between randomized groups, adjusting for baseline depression/anxiety symptoms, gender, and research center.</jats:p></jats:sec>jats:secjats:titleResults</jats:title>jats:pA total of 643 (51%) participants attended the 5‐year study follow‐up visit. There was no evidence of a difference between the randomized groups for 5‐year changes in depression (BI: −0.08 ± 3.29; CP12: 0.02 ± 3.01; CP52: −0.09 ± 3.41) or anxiety (BI: 0.16 ± 3.50; CP12: −0.05 ± 3.55; CP52: −0.66 ± 3.59) symptoms.</jats:p></jats:sec>jats:secjats:titleConclusions</jats:title>jats:pThis study found no evidence that commercial weight management programs differed in 5‐year changes in depression and anxiety symptoms, compared with BI. These are average effects; some individuals experienced increases or decreases in symptoms. Future research should investigate who is at most risk of mental health declines and investigate how to support them. Future trials should transparently report long‐term mental health outcomes to strengthen understanding.</jats:p></jats:sec>
