Exercise Adherence in Persons with Type 2 Diabetes and Relationship to Diabetes Control

摘要

The purpose of this pilot study was to examine exercise adherence in persons with Type 2 diabetes and how the stages of change in exercise are related to metabolic control. A sample of 28 persons with Type 2 diabetes in ages ranging from 53 to 77 (16 males and 12 females), was studied using the Transtheoretical Theory, of Change. Surveys on the Stages of Change, Processes of Change and Self-Efficacy, developed by Marcus, Rossi, Selby, Niaura, & Abrams (1992) were mailed to participants and followed-up with a telephone Stanford 7- day activity,, recall. Subjects were assigned a stage of exercise adoption (Precomtemplation, Contemplation, Preparation, Action, and Maintenance) based on answers to questions in the mailed survey. Metabolic control was related to stage of exercise adoption. Reported physical activity,' also were related to stages of change in exercise. The telephone survey was used as an internal validation of the mailed self-report. Processes of change in exercise and self- efficacy also were explored in relation to stages of change. Distribution among the stages was unusual. Half of the participants fell into the highest stage of exercise adoption (maintenance). Marcus, Rossi, et al. (1992) only found 22% of their sample to be in this stage. Also two of the stages (precontemplation and action) only had one individual and therefore the stages were collapsed into three stages combining precontemplation with contemplation and action with maintenance for many statistical calculations. In addition, for some calculations, the group was divided into exercisers (Stages 1,2,&3) and non- exercisers (Stages 4&5), The most frequent type of exercise reported was walking. Thirty-five percent chose walking alone and an additional 60% who chose walking or treadmill as part of their fitness program.
