title: [Effects of rehabilitation on functional capacity, obesity and health behavior, among cardiac patients with DM2].
abstract: Present study examines the prevalence of type 2 diabetes (DM2) in patients attending cardiac rehabilitation (CR) compared to the general population utilising data from the Icelandic Heart Association population study. The study also examined the efficacy of CR for promoting health behaviors.
  
  
  
  A prospective study among DM2 patients attending CR at Reykjalundur Rehabilitation centre. The DM2 group was compared to other cardiac patients, with respect to obesity and exercise capacity at the beginning and end of 4-6 weeks of CR. Additionally, in the DM2 group, weight, smoking cessation, physical activity and walking capacity were assessed at 3 and 6 months follow-ups.
  
  
  
  The prevalence of DM2 was 2-4 times higher in CR participants than in the general population. Compared to other CR participants, the DM2 group was heavier, with increased waist circumference and less exercise capacity. During the CR both groups lost weight and waist circumference decreased to similar extent, but the exercise capacity increased less in the DM2 group. In follow up after 6 months the DM2 group´s weight and glucose values were back to same level as before CR, but waist circumference was still decreased and they retained increased physical activity and walking capacity.
  
  
  
  DM2 is more prevalent among patients in cardiac rehabilitation than in the general population. The DM2 group was more obese, had lower exercise capacity and responded somewhat less to CR than other cardiac patients. Follow up after 6 months did however show that they continued their regular exercise and walking capacity was still retained.
