Background Empirical evidence suggests Roux-en-Y gastric bypass (RYGB) increases risk of developing alcohol use disorder (AUD). However, prospective assessment of substance use disorders (SUD) following bariatric surgery is limited. Objective To report SUD-related outcomes following RYGB and laparoscopic adjustable gastric banding (LAGB). To identify factors associated with incident SUD-related outcomes. Setting Ten US hospitals. Methods The Longitudinal Assessment of Bariatric Surgery-2 is an observational cohort study. Participants self-reported past-year AUD symptoms (determined by the Alcohol Use Disorders Identification Test), illicit drug use (cocaine, hallucinogens, inhalants, phencyclidine, amphetamines, or marijuana), and SUD treatment (counseling or hospitalization for alcohol or drugs) presurgery and annually postsurgery for up to seven years through January 2015. Results Of 2348 participants who underwent RYGB or LAGB, 2003 completed baseline and follow-up assessments (79.2% women, baseline median age 47 years, median body mass index 45.6). The year-5 cumulative incidence of postsurgery onset AUD symptoms, illicit drug use, and SUD treatment were 20.8% (95%CI, 18.5-23.3), 7.5% (95%CI, 6.1-9.1), and 3.5% (95%CI, 2.6-4.8), respectively, post-RYGB, and 11.3% (95%CI, 8.5-14.9), 4.9% (95%CI, 3.1-7.6), and 0.9% (95%CI, 0.4-2.5) post-LAGB. Undergoing RYGB vs. LAGB was associated with higher risk of incident AUD symptoms (AHR=2.08 [95%CI, 1.51-2.85]), illicit drug use (AHR=1.76 [95%CI, 1.07-2.90]) and SUD treatment (AHR=3.56 [95%CI, 1.26-10.07]). Conclusions Undergoing RYGB vs. LAGB was associated with twice the risk of incident AUD symptoms. One-fifth of participants reported incident AUD symptoms within 5 years post-RYGB. AUD education, screening, evaluation, and treatment referral should be incorporated in pre- and postoperative care.

Objective To examine changes in depressive symptoms and treatment in the first three years following bariatric surgery. Design and Methods The Longitudinal Assessment of Bariatric Surgery-2 is an observational cohort study of adults (n=2,458) who underwent a bariatric surgical procedure at one of ten US hospitals between 2006–9. This study includes 2,148 participants who completed the Beck Depression Inventory (BDI) at baseline and ≥ one follow-up visit in years 1–3. Results At baseline, 40.4% self-reported treatment for depression. At least mild depressive symptoms (BDI score≥10) were reported by 28.3%; moderate (BDI score 19–29) and severe (BDI score ≥30) symptoms were uncommon (4.2% and 0.5%, respectively). Mild-to-severe depressive symptoms independently increased the odds (OR=1.75; p=.03) of a major adverse event within 30 days of surgery. Compared with baseline, symptom severity was significantly lower at all follow-up time points (e.g., mild-to-severe symptomatology was 8.9%, 6 months; 8.4%, 1yr; 12.2%, 2yrs; 15.6%, 3yrs; ps<.001), but increased between 1 and 3 years postoperatively (p<.01). Change in depressive symptoms was significantly related to change in body mass index (r=.42; p<0001). Conclusion Bariatric surgery has a positive impact on depressive features. However, data suggest some deterioration in improvement after the first postoperative year.

WHAT'S KNOWN ON THIS SUBJECT: Adverse effects of excess weight are likely related to both obesity severity and duration. Little is known about the contribution of adolescent weight status to development of specific comorbid conditions in adults.WHAT THIS STUDY ADDS: Severe obesity at age 18 was independently associated with increased risk of lower extremity venous edema, walking limitation, kidney dysfunction, polycystic ovary syndrome, respiratory conditions, diabetes, and hypertension in adulthood.abstract OBJECTIVE: To test the hypothesis that adolescent obesity would be associated with greater risks of adverse health in severely obese adults. METHODS:Before weight loss surgery, adult participants in the Longitudinal Assessment of Bariatric Surgery-2 underwent detailed anthropometric and comorbidity assessment. Weight status at age 18 was retrospectively determined. Participants who were $80% certain of recalled height and weight at age 18 (1502 of 2308) were included. Log binomial regression was used to evaluate whether weight status at age 18 was independently associated with risk of comorbid conditions at time of surgery controlling for potential confounders.RESULTS: Median age and adult body mass index (BMI) were 47 years and 46, respectively. At age 18, 42% of subjects were healthy weight, 29% overweight, 16% class 1 obese, and 13% class $2 obese. Compared with healthy weight at age 18, class $2 obesity at age 18 independently increased the risk of lower-extremity venous edema with skin manifestations by 435% (P , .0001), severe walking limitation by 321% (P , .0001), abnormal kidney function by 302% (P , .0001), polycystic ovary syndrome by 74% (P = .03), asthma by 48% (P = .01), diabetes by 42% (P , .01), obstructive sleep apnea by 25% (P , .01), and hypertension (by varying degrees based on age and gender). Conversely, the associated risk of hyperlipidemia was reduced by 61% (P , .01). CONCLUSIONS:Severe obesity at age 18 was independently associated with increased risk of several comorbid conditions in adults undergoing bariatric surgery.

Objective To evaluate change in sedentary behavior (SB) and physical activity (PA) over three years following bariatric surgery. Methods A subset of participants in an observational study (n=473 of 2458; 79% female, median body mass index 45kg/m2) wore an activity monitor pre-surgery and at 1–3 annual post-surgery assessments. Results Over the first year, on average, sedentary time decreased from 573 (95%CI 563–582) to 545 (95%CI 534–555) min/d and moderate-to-vigorous intensity PA (MVPA) increased from 77 (95%CI: 71–84) to 106 (95%CI: 98–116) min/wk, or 7 (95%CI: 5–10) to 24 (95%CI: 18–29) min/wk in MVPA bouts ≥10 minutes. There were no changes in these parameters from years 1 to 3 (P for all>.05). The percentage of participants achieving ≥150 min/wk of bout-related MVPA was not different at year 3 [6.5% (95%CI: 3.1–12.7)] vs. pre-surgery [3.4% (95%CI: 1.8–5.0); p=.45]. Most participants followed SB and PA trajectories that paralleled mean change and were consistent with their pre-surgery position in relation to the group. Conclusions On average, bariatric surgical patients make small reductions in SB and increases in PA during the first post-surgery year, which are maintained through 3 years. Still, post-surgery PA levels fall short of PA guidelines for general health or weight control.
