title: Lifestyle Changes After a Diagnosis of Type 2 Diabetes.
abstract: OBJECTIVE
  Whether patients with type 2 diabetes change their lifestyle in response to their diagnosis and maintain behavior changes is unclear. This study aimed to1) compare changes in lifestyle behaviors among participants who were newly diagnosed with type 2 diabetes and those never diagnosed with type 2 diabetes and2) investigate changes in lifestyle behaviors in relation to the duration of newly diagnosed type 2 diabetes.
  
  
  METHODS
  We used self-reported information from the New South Wales 45 and Up Study and a follow-up study. Changes in body weight; amount of walking, moderate to vigorous physical activity (MVPA), and sitting; fruit and vegetable consumption; and smoking status and number of cigarettes smoked were used as measures of health behavior change. These variables were compared between participants in a "new type 2 diabetes" group and a "no type 2 diabetes" group.
  
  
  RESULTS
  The new type 2 diabetes group had a smaller decrease in vegetable consumption, lost more weight, and were more likely to quit smoking than the no type 2 diabetes group. MVPA, fruit consumption, and number of cigarettes smoked did not change significantly for either group. Although no significant changes were found in any of the health behaviors based on time since diagnosis, the magnitude of changes in weight and walking increased as duration of diagnosis increased, whereas changes in MVPA, number of cigarettes smoked, and proportion of participants who quit smoking decreased.
  
  
  CONCLUSIONS
  In this population-based study, participants with incident type 2 diabetes reported only minimal changes in their lifestyle factors after receiving their diagnosis.
