Abstract

BACKGROUND:

Bariatric surgery facilitates substantial and durable weight loss; however, outcomes vary. In addition to physiological and technical factors, weight loss efficacy is dependent on modification of behavior to maintain a long-term change in energy balance. This study aimed to assess the extent and nature of change in energy intake and physical activity and identify factors associated with percentage weight loss (%WL) 12 months after laparoscopic adjustable gastric banding (LAGB).

METHODS:

129 bariatric surgery candidates (26 men/103 women, mean age 45.2 +/- 11.5, mean body mass index [BMI] 44.3 +/- 6.8, range 31.9 to 66.7) completed the study. Data were collected at baseline and 12 months. Validated questionnaires included the Cancer Council Victoria Food Frequency Questionnaire, Three Factor Eating Questionnaire, Short Form-36, Baecke Physical Activity Questionnaire, and Beck Depression Inventory. Symptoms of "non-hungry eating," "emotional eating," and "grazing" were assessed.

RESULTS:

Mean %WL was 20.8 +/- 8.5%, and excess weight loss was 50.0 +/- 20.7 (p < 0.001). Mean total energy intake reduced from 9,991 +/- 3,986 kj to 4,077 +/- 1,493 kj (p < 0.001). Average leisure time and sport-related physical activity scores increased (both p < 0.001). Regression analysis identified baseline BMI (beta = 0.241; p = 0.002), subjective hunger (beta = -0.275; p = 0.001), physical function (beta = 0.309; p < 0.001), and leisure time physical activity (beta = 0.213; p = 0.010) as independent predictors of %WL, total R (2) 0.34%. "Non-hungry eating" and symptoms of depression were also related to poorer %WL.

CONCLUSION:

LAGB affects marked behavior change and facilitates substantial weight loss in the first 12 months. However, variations in adopted behaviors can affect energy balance and weight loss success. Achievement and maintenance of favorable behaviors should be an important consideration during on-going postsurgical review and counseling. Management should include adequate band adjustment to control physical hunger, optimization of physical function and activity, and reinforcement of strategies to reduce energy intake.
