ABSTRACT
BACKGROUND:
People with obesity and type 2 diabetes (T2D) have reduced life expectancy, partly explained by increased risk of cardiovascular diseases and cancer. Here, we examined whether 2-year diabetes remission after bariatric surgery or usual care is associated with long-term mortality. MATERIALS ANDMETHODS:
This report includes 586 participants with obesity and concomitant T2D from the prospective Swedish Obese Subjects (SOS) cohort study; 338 underwent bariatric surgery and 248 received usual obesity care. At inclusion, age was 37-60 years and BMI ≥34 kg/m2 in men and ≥38 kg/m2 in women. Median follow-up was 26.2 years (interquartile range 22.7-28.7). Diabetes status was determined using self-reported data on diabetes medication and in-study measures of blood glucose and HbA1c. The study was cross-linked to Swedish national registers for data on morbidity, death, and emigration.RESULTS:
Overall, 284 participants, 71.9% of surgery and 16.5% of usual care patients, were in remission at the 2-year examination. During follow-up, mortality rates were 16.6 deaths per 1000 person-years (95% CI13.7-20.1) in the remission subgroup and 26.0 deaths per 1000 person-years (95% CI22.2-30.4) in the non-remission subgroup (adjusted hazard ratio (HRadj)=0.71, 95% CI0.54-0.95, P=0.019). The adjusted median life expectancy in the remission subgroup was 2.5 years (95% CI0.3-4.7) longer than in the non-remission subgroup. Specifically, remission was associated with decreased cardiovascular mortality (sub-HRadj=0.54, 95% CI0.35-0.85, P=0.008), but no detectable association with cancer mortality was found (sub-HRadj=1.06, 95% CI0.60-1.86), P=0.841).CONCLUSION:
In this post-hoc analysis of data from the SOS study, patients who achieved short-term diabetes remission had increased life expectancy and decreased cardiovascular death over up to 32 years of follow-up. Future studies should confirm these findings.
