Evaluation of pre- and postoperative physical activity participation in laparoscopic gastric banding patients.
BACKGROUND
Weight loss outcomes following laparoscopic adjustable gastric banding (LAGB) are widely variable, and physical activity (PA) participation improves these results. The purpose of this study was to retrospectively describe PA behaviors before and after LAGB and to evaluate the impact of PA on weight loss outcomes.


METHODS
Participants were 172 individuals (145 females, mean age 43.3 ± 12.0 years, mean body mass index [BMI] 43.8 ± 5.1 kg/m(2)) who underwent LAGB at a university medical center. Height, weight, presence of comorbidities, and PA participation were assessed prior to and 3, 6, and 12 months after surgery. Those who reported engaging in ≥ 150 min of weekly moderate-to-vigorous PA (MVPA) were considered active.


RESULTS
Less than 40 % of participants were active prior to surgery, while 31 % of those who were inactive before surgery became active at 6 months of follow-up. Unlike previous reports on gastric bypass patients, there was no statistically significant (p > 0.05) relationship between postoperative PA status and weight loss outcomes at 3, 6, or 12 months in LAGB patients. Interestingly, participants who reported ≥ 150 min of MVPA prior to surgery achieved approximately 10 % greater excess weight loss (p < 0.05) and a 2.4-kg/m(2) greater decrease in BMI (p < 0.05) at 1 year post-LAGB compared to those who were inactive preoperatively.


CONCLUSIONS
In our sample, higher levels of preoperative PA participation were associated with improved weight loss outcomes following LAGB. We posit that higher preoperative volumes are indicative of habitual exercise and that those who report being active prior to surgery are likely to maintain these behaviors throughout follow-up.
