title: Health-Related Quality of Life after Bariatric Surgery and its Correlation with Glycaemic Status in Hong Kong Chinese Adults.
abstract: BACKGROUND
  To evaluate health-related quality of life (HRQOL) following bariatric surgery and its correlation with different glycaemic status in Hong Kong Chinese adults.
  
  
  METHODS
  In 2002-2008, obese Chinese adults were recruited for bariatric surgery, undergoing laparoscopic adjustable gastric banding or laparoscopic sleeve gastrectomy. Patients were invited to complete the Chinese Hong Kong Medical Outcomes Study Short-Form Health Survey (SF-36) at baseline and at 1-year post operation.
  
  
  RESULTS
  Sixty patients (60 % female) completed baseline and 1-year follow-up HRQOL assessments. Mean age was 38 years and mean BMI was 41.6 kg/m(2). At baseline, 30.0 % of patients had diabetes and 31.7 % prediabetes. Mean absolute weight reduction 1 year after bariatric surgery was 19.8 kg. Statistically significant improvements in SF-36 scores were demonstrated in all physical domains and in three of the four psychological domains. Greater body weight reduction was associated with greater improvements in certain physical domains postoperatively. After adjusting for co-variables, abnormal glucose tolerance was associated with greater improvements in five of the eight HRQOL domains.
  
  
  CONCLUSIONS
  Bariatric surgery resulted in significant gains in HRQOL as well as significant reductions in body weight in obese Chinese adults. This study suggests that bariatric surgery offers greater HRQOL improvements in patients with prediabetes and diabetes compared with normoglycaemic individuals.
