title: Type 2 diabetes mellitus patients with poor glycaemic control have lower quality of life scores as measured by the Short Form-36.
abstract: BACKGROUND
  This study aimed to compare the quality of life based on the Short Form-36 (SF-36) between two different groups of type 2 diabetes mellitus patients with glycaemic control: those with a glycosylated haemoglobin (HbA1c) level at or below 7.5 percent and those above 7.5 percent.
  
  
  METHODS
  In this cross-sectional study, a generic SF-36 questionnaire was self-administered to patients with type 2 diabetes mellitus. Based on the HbA1c level, the mean SF-36 scale scores were compared. The analysis of covariance was used to obtain the adjusted mean scores of the SF-36 scales while controlling for age and duration of type 2 diabetes mellitus.
  
  
  RESULTS
  150 patients with type 2 diabetes mellitus were analysed. There were 63 (42 percent) women and 87 (58 percent) men, and their mean HbA1c level was 8.9 percent (SD 2.4 percent). When comparing the two groups of patients with different HbA1c levels, the adjusted means of four scales: physical health functioning, general health, social functioning and mental health, differed significantly between the two. The SF-36 scale scores in type 2 diabetes mellitus patients were also lower than those of the SF-36 norms for the Malaysian population.
  
  
  CONCLUSIONS
  Type 2 diabetes mellitus patients with poor glycaemic control had lower mean SF-36 scores in physical functioning, general health, social functioning and mental health, and the SF-36 scores in these patients were also lower than the SF-36 norms of the Malaysian population.
