摘要

Background

Food addiction (FA) is prevalent among individuals undergoing metabolic and bariatric surgery (MBS), but few studies have investigated the prevalence and correlates of post-surgical FA over longer periods. We report an observational, longitudinal study investigating prevalence of post-surgical FA at 5 and 10 years following MBS.

Methods

Participants in the Oslo Bariatric Surgery Study (OBSS) completed the modified Yale Food Addiction Scale 2.0 (mYFAS) and measures of psychological functioning and weight outcomes (% total weight loss: %TWL and % weight recurrence: %WR) at 5 and 10 years follow-up.

Results

N = 173 of 224 (23% lost-to-follow-up) participants (73% women, 93.6% Roux-en-Y gastric bypass) completed the mYFAS 2.0 at 5 years and 10 years following MBS. The prevalence of FA was 12.9% at 5 years and 8.4% at 10 years after MBS. A higher number of FA symptoms at 5 years significantly predicted less %TWL and lower psychological functioning at 10 years. At 10 years, the majority of individuals with FA had moderate or severe symptoms and 3% were new-onset cases of FA. Higher FA at 10 years was concurrently associated with less %TWL, greater %WR, and lower psychological functioning at the 10-year follow-up (p’s < 0.001).

Conclusions

The prevalence of FA decreased from 12.9 to 8.4% between 5 and 10 years following MBS. We observed prospective and concurrent associations between FA symptoms and poorer weight loss and mental health outcomes. The presence of post-operative FA may be an important target for continued assessment and follow-up care to improve longer-term outcomes.
