title: [The influence of quality of life in treatment adherence of diabetic patients: a systematic review].
abstract: OBJECTIVE
  To verify the influence of quality of life in treatment adherence of patients with diabetes mellitus.
  
  
  METHODS
  Systematic review of the literature using the databases MEDLINE, CINAHL, Scopus, LILACS, SciELO and Web of Science with studies published between 2003 and 2014 in English, Portuguese or Spanish.
  
  
  RESULTS
  Six studies were included in the review, three were identified as having better quality of life scores, being related to better adherence to diabetes treatment measured by glycated hemoglobin or characteristics related to diet, exercise, use of medication and foot care. No association was found between quality of life and adherence in two investigations and a study found a negative association between these variables.
  
  
  CONCLUSIONS
  There is causal relationship between quality of life and adherence with diabetes treatment. It is suggested that psychosocial aspects of patients should be considered by health professionals in the search for better clinical outcomes in diabetes care.
