TOPLINE:
Adolescents with severe obesity who undergo bariatric surgery may have a continuing need for mental health treatment and an increased risk for alcohol use disorder after the procedure.
METHODOLOGY:
- Researchers evaluated the long-term effects of bariatric surgery on the mental health of 1554 adolescents (75% women) with severe obesity who underwent bariatric surgery in Sweden between 2007 and 2017.
- At the time of surgery, the mean age was 19.0 years, and the mean body mass index was 43.7.
- A general population reference group of 15,540 adolescents was created by matching 10 comparators each to adolescents in the surgery group by age, sex, and country of residence.
- Information on psychiatric healthcare use and filled psychiatric drug prescriptions for 5 years before surgery and the first 10 years after surgery were obtained from national registers.
- The number of visits for self-harm and substance use disorder and the number of filled prescriptions for any psychiatric drug, antidepressants, and anxiolytics were other outcomes of interest.
TAKEAWAY:
- At 5 years before surgery, the prevalence of psychiatric healthcare visits (prevalence difference [Δ], 3.7%) and of psychiatric drug use (Δ, 6.2%) was higher in the surgery vs reference group.
- The preoperative trajectories continued and grew post-surgery, with the differences in psychiatric healthcare visits (Δ, ~12%) and psychiatric drug use (Δ, 20.4%) between the groups peaking at 9 and 10 years post surgery, respectively.
- A low prevalence of healthcare visits for substance use disorder in both groups grew to about 5% of adolescents in the surgery group after 10 years, driven primarily by alcohol use, compared with about 1% of adolescents in the reference group (Δ, 4.3%).
- Surgery is an obesity treatment, leading to sustainable weight loss, cardiometabolic health, and physical quality of life, but mental health improvements cannot be expected at the group level.
IN PRACTICE:
“Adolescent patients should be informed of the increased risk for alcohol use disorder and that they might continue needing mental health treatment,” the authors wrote.

Gustaf Bruze, PhD, from the Department of Medicine, Clinical Epidemiology Division, Karolinska Institutet, Solna, and Kajsa Jarvholm, PhD, from the Department of Psychology, Lund University, Lund, Sweden, led this study, which was published online in The Lancet Child & Adolescent Health.
LIMITATIONS:
The findings may have limited generalizability to other settings, as the study was performed in Sweden with a predominantly White population undergoing Roux-en-Y gastric bypass in a universally accessible healthcare system. Moreover, there was a shortage of nonsurgically treated adolescents with severe obesity for comparison. Patients undergoing surgery may have easier access to healthcare than the general population, which could account for an increase in healthcare visits.
DISCLOSURES:
This study was supported by the Swedish Research Council and the Swedish Research Council for Health, Working Life, and Welfare. Two authors were the current or previous director of the Scandinavian Obesity Surgery Registry. Several authors declared receiving personal fees, participating in advisory boards and educational activities, and having other ties with Ethicon Johnson & Johnson, and Novo Nordisk.
