It is already known that physical activity is very important measure in treatment of type 2 diabetes mellitus, but in spite of that, in our country, there is neither its adequate use in therapy, nor the evaluation of its level in type 2 diabetics.
The aim of this study is to evaluate the level of physical activity in patients with type 2 diabetes, by using the questionnaire for evaluation of physical activity, based on the International Physical Activity Questionnaire used in the Framingham Heart Study.
The level of physical activity is evaluated by the Physical Activity Index (PAI), which is calculated by summing the number of hours spent in each activity intensity level (vigorous, moderate, light physical activity, sedentary behavior and sleep) and multiplying by a respective weight factor, derived from the estimated oxygen consumption requirement for each intensity level (Metabolic Equivalent, MET). The results were compared to the results of healthy control subjects.
The estimated value of PAI in patients with type 2 diabetes was 34.1 ± 6.4 and in controls 37.6 ± 6.4. The energy expenditure in the subgroup of patients with type 2 diabetes with predominantly sedentary behavior was 852 kcal minor than in the control group.
The results of this investigation show very low level of physical activity in
patients with type 2 diabetes and its correlation with coronary risk factors.
