Abstract

Background: The health benefits of regular physical activity are well known and include the prevention of chronic diseases such as obesity, type 2 diabetes, and cardiovascular diseases. Still, only 20% of U.S. adults report meeting the Physical Activity Guidelines for Americans. With approximately 43% of U.S. jobs considered sedentary, there is a need for effective workplace physical activity interventions. MapTrek is a mobile health game designed to increase daily physical activity in a low-cost, scalable, and enjoyable way.

Objective: The purpose of the present study was to test the efficacy of MapTrek for increasing daily steps and moderate-intensity steps over 10 weeks in a sample of sedentary office workers.

Methods: Participants included 144 full-time sedentary office workers ages 21-65 who reported sitting at least 75% of their workday. Each participant received a Fitbit Zip to wear daily throughout the intervention. Participants were randomized to either a: 1) Fitbit only group or 2) Fitbit + MapTrek group. Physical activity outcomes and intervention compliance were measured with the Fitbit activity monitor.

Results: The Fitbit + MapTrek group significantly increased daily steps (+2,091.5 steps/day) and active minutes (+11.2 minutes/day) compared to the Fitbit only arm.

Conclusions: These data support MapTrek as an effective approach for increasing physical activity at a clinically meaningful level in sedentary office workers.

Public Abstract

Partaking in regular physical activity is known to reduce the risk of chronic diseases like obesity, type 2 diabetes, and heart diseases. These diseases are common cause of death today, with heart disease being the leading cause of death in America. Even so, only 20% of U.S. adults report meeting the Physical Activity Guidelines for Americans. These guidelines, updated in 2008 by the World Health Organization, outline the recommended amount and types of physical activity to do to maintain or improve health. With approximately 43% of U.S. jobs considered sedentary, current workplace interventions aimed at increasing daily physical activity leave something to be desired. MapTrek is a mobile health game designed to increase daily physical activity in a fun, low-cost, and scalable way. The purpose of this study was to test MapTrek’s ability to increase daily physical activity over 10 weeks in a group of sedentary office workers.

A total of 144 full-time sedentary office workers ages 21-65, who reported sitting at least 75% of their workday were enrolled in this study. Each participant was given a Fitbit Zip to wear daily throughout the intervention. Participants were randomized to either a 1) Fitbit only group or 2) Fitbit + MapTrek group. Daily steps and adherence to the intervention were measured with the Fitbit activity monitor. Results showed the Fitbit + MapTrek group significantly increased daily steps (+2,091.5 steps/day) and active minutes (+11.2 minutes/day) compared to the Fitbit only group. These data indicate MapTrek increased daily physical activity in our sample. Future studies are needed to confirm these findings in other populations.
