Psychosocial and physical activity changes after gastric restrictive procedures for morbid obesity.
Gastric restrictive procedures for morbid obesity are frequently performed to reduce problems arising from the physical limitations and social isolation of massive obesity. Numerous reports have described changes in weight after gastric restrictive operations, yet few studies have documented changes in the secondary effects of obesity. This report deals with changes in psychosocial status and physical activity occurring in 240 patients who remained in the study 3 years after surgery. These patients were members of a group of 310 patients who were entered into a prospective randomized trial to assess the relative benefits of three forms of gastric restrictive procedure. Prior to operation, and at yearly intervals after operation, the physical activities and psychosocial status of each patient was assessed by a standardized semi-structured interview. At the time of the three-year interview the median weight loss for these patients was 29.5 kg which represents 53% of excess weight lost. This weight loss was associated with a marked reduction in the amount of food eaten. There was a significant increase in the number of patients smoking more than 20 cigarettes a day and a mild increase in alcohol intake. There were significant improvements in the level of self-image and state of happiness. The social lives and sex lives of the majority of patients were improved and a significantly greater number of patients reported being in a stable emotional relationship at 3 years after operation than did so pre-operatively. There was a marked increase in the number of patients in full-time or part-time employment from 38% prior to surgery to 60% at 3 years after operation.(ABSTRACT TRUNCATED AT 250 WORDS)
