Objectives: The purpose of this study is to analyze the changes in the body indices and nutritional indices between the smartphone user group who received the remote healthcare services and paper record group who performed only the self-record and to analyze the correlation between changes of body indices and changes of nutrition indices in the SmartCare Service Pilot Project conducted in 2011. Methods: Among 422 participants who were randomized in this study, the final analysis subjects were a total of 324 people, excluding the people who dropped out during the 6-month service period and who missed dietary intake records. For evaluation, the changes were compared with baseline and after 6 months by comparing 6 types of body indices and 14 types of nutritional indices and the correlation of changes were analyzed for elements of each evaluation index. Results: Changes in body indices, the smartphone user group showed statistically significant improvement much higher in weight, BMI, waist circumference, and percentage of body fat than the paper record group (p<0.05). Also, changes in nutritional indices, Energy, Carbohydrate, Protein, Fat, Niacin, Ca, and Cholesterol showed more statistically significant reduction (p<0.05). In addition, correlation of changes in the body indices and nutritional indices, the body indices of smartphone user group showed the statistically significant positive correlation with Energy, Carbohydrate, Protein, Fat, Niacin, Ca, P, Mg, and Cholesterol (p<0.05). On the other hand, the body indices of the paper record group didn’t show any statistically significant correlation with all elements of nutritional indices. Conclusions: The smartphone user group showed more improved indices related to obesity compared to the paper record group and it was confirmed that the most changes of body indices and nutritional indices have the positive correlation.
