[Purpose] The aim of this study was to understand the factors involved in increasing
physical activity levels in type 2 diabetes mellitus patients for improved glycemic
control. [Subjects] The subjects were 101 type 2 diabetes mellitus patients who had
completed an inpatient diabetes education program. [Methods] The survey evaluated physical
activity levels on the basis of the International Physical Activity Questionnaire and a
questionnaire listing physical and psychosocial factors. [Results] Four
variables—participation or non-participation in farm work, presence or absence of a job,
stage of change in attitude toward exercise behavior, and social support—accounted for 34%
of physical activity levels in these diabetes mellitus patients. The Spearman’s rank
correlation coefficient between physical activity level and HbA1c was −0.31. [Conclusion]
Intervention in terms of practical use of living environments, promotion of exercise
behavior, and social support may be effective in helping to improve glycemic control.
[Purpose] We investigated whether the International Physical Activity Questionnaire (IPAQ) was valid for use in assessing the physical activity levels of diabetes patients, who are expected to have reduced physical activity.[Subjects] The subjects were 16 type 2 diabetes mellitus patients.[Method] Using Pearson's correlation coefficient and Student's t-test we investigated the correspondence of 1-week exercise energy consumption calculated from the Short Version of the Japanese IPAQ, and 1-week exercise energy consumption calculated by a Suzuken Lifecorder GS/Me. [Results] We found no significant difference between the two measures according to the Student's t-test result, and the correlation coefficient for the two measures was, r=0.69.[Conclusion] The level of physical activity of diabetes patients calculated from IPAQ was confirmed and validated against the level of physical activity measured by Lifecorder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
