Innovative use of mobile phones to promote physical activity and nutrition across the lifespan (the IMPACT research group) – Marie Löf

The widespread adoption of mobile phones provides a promising opportunity to improve health. The use of mobile technology (such as the Internet and smartphone applications), referred to as ‘Mobile Health’ or mHealth, is becoming popular to assist, inform and guide people to a healthy lifestyle.  Our research group utilizes mobile phones to develop and evaluate new methods for dietary and physical activity assessments as well as to deliver obesity prevention and physical activity interventions. Our research group covers studies in children, pregnant women as well as adults. 

The MINISTOP trial

Childhood overweight and obesity is a global health problem. Traditional obesity prevention programs are time and cost intensive. The use of mobile phone technology (mHealth) through smartphone applications (apps) to deliver such interventions has recently attracted interest. In the MINISTOP trial, we investigated the effectiveness of a 6-month mHealth parental intervention on body fatness, dietary habits, and physical activity in 4-year-olds. The interest for the study among parents was very high and it has progressed very well. Data collection was finalized in October 2015. We enrolled 315 families and 263 completed both follow-ups (the power goal was 300 with 200 finalizing both follow-ups).

The study is supported by the Swedish Research Council; the Swedish Research Council for Health, Working Life and Welfare, Swedish Nutrition Foundation; Bo and Vera Axson Johnsons Foundation, Karolinska Institute, and Henning and Johan Throne-Holst Foundation.

The FUNKID study

According to WHO, childhood obesity is one of the most serious public health challenges of the 21st century. The mechanisms underlying overweight and obesity in young children are largely unknown, but factors early in life, maybe already in utero may be important. In the FUNKID study we evaluate associations between body composition and physical activity from birth throughout child in 300 children. Currently, the children are being investigated at 9 years of age. 

SCAMPI – The Smart City Active Mobile Phone Intervention

Physical inactivity is still a major public health problem. Active transportation i.e. walking or cycling for transport can contribute to greater total physical activity. In this study we will evaluate whether a mobile phone app can increase active transportation in adults. Recruitment will be initiated in September 2017. The study is financed by Forte.
