OBJECTIVE - Because of other competing priorities, physical activity (PA) i
s seldom addressed in a consistent way in either primary care or diabetes e
ducation. This 8-week pilot study evaluated the short-term benefits of an I
nternet-based supplement to usual care that focused on providing support fo
r sedentary patients with type 2 diabetes to increase their PA levels.
RESEARCH DESIGN AND METHODS - A total of 78 type 2 diabetic patients (53% f
emale, average age 52.3 years) were randomized to the Diabetes Network (D-N
et) Active Lives PA Intervention or an Internet information-only condition.
The intervention condition received goal-setting and personalized feedback
, identified and developed strategies to overcome barriers, received and co
uld post messages to an on-line "personal coach," and were invited to parti
cipate in peer group support areas. Key outcomes included minutes of PA per
week and depressive symptomatology.
RESULTS - There was an overall moderate improvement in PA levels within bot
h intervention and control conditions, but there was no significant improve
ment in regard to condition effects. There was substantial variability in b
oth site use and outcomes within the intervention and control conditions, I
nternal analyses revealed that among intervention participants, those who u
sed the site more regularly derived significantly greater benefits, whereas
those in the control condition derived no similar benefits with increased
CONCLUSIONS- Internet-based self-management interventions for PA and Other
regimen areas have great potential to enhance the care of diabetes and Othe
r chronic conditions. We conclude that greater attention should be focused
on methods to sustain involvement with Internet-based intervention health p
romotion programs over time.
