DescriptionBackground: Obesity is a systemic disease that increases exposure to other chronic diseases. Phone applications have increasingly been used to improve physical activities, but there is little evidence of their success and consistent use.
Purpose: This study aimed to explore the use of a smartphone exercise app as a technological intervention within the primary care setting to reduce rates of obesity among adult women.
Method: Thirty-one women (16 in treatment and 15 in control) aged 18 - 64 years, attending a primary care center, who had never used a phone application for weight reduction, were enrolled. The treatment group used the Fitbit app for self-monitoring. The body mass index and the motivation for physical activity (MPAM-R) scores were computed at the beginning and end of the study. Paired and independent sample T-tests were used to assess the differences within and across groups, respectively.
Results: The mean BMI in the treatment and control groups decreased, although the decrease within and between groups was not statistically significant. Also, the mean scores of the MPAM-R among the treatment and control groups increased significantly within each group. However, across the treatment and control groups, the mean differences were not statistically significant.
Conclusion: While there was a substantial increase in the motivation for physical activities and a reduction in the BMI with the use of the Fitbit app, a more extensive study may be required to assess the true effect.
