The laparoscopic adjustable gastric band [LAGB] is a form of bariatric surgery to assist individuals in losing weight when behavioural and dietary changes alone have been unsuccessful. There has been some debate about how age at time of surgery impacts on weight loss, but there is little known about the impact of age on psychological changes. As part of a longitudinal study exploring the impact of LAGB, 73 participants (aged between 30 and 74 years) were weighed and completed a number of validated psychometric scales seven times over a five year period. Individuals were split into two groups, those aged ≤ 49 and ≥50 years for analysis. Correlations between psychometric measures and Body Mass Index [BMI] at each time point indicated more significant correlations were present for individuals aged ≤ 49 years. Repeated-measures ANOVA exploring changes in BMI and psychological states from pre to five years post-LAGB indicate that BMI reduces and psychological difficulties improve in the years following surgery. These results suggest individuals aged ≤ 49 years have more psychological concerns regarding their weight that need addressing than individuals aged ≥ 50 years.
