Brief Summary:
This study aims to evaluate the effects of a mobile phone-based dietary and physical activity intervention on body fatness, dietary intake and physical activity of preschoolers

Condition or disease Intervention/treatment Phase
Obesity Behavioral: Mobile phone based intervention Not Applicable

Detailed Description:
Childhood overweight and obesity is an increasing health problem globally, and can be established as early as 2-5 years of age. Mobile phone based (mHealth) interventions have been successful for weight management in adults; however, their potential in young children is yet to be established. Therefore, the ultimate goal of MINISTOP (Mobile-based INtervention Intended to STop Obesity in Preschoolers) trial is to help parents of four year old children to achieve a healthy weight and body fat via a smartphone app (MINISTOP). More specifically this trial aims to reduce body fat (primary outcome), increase the intake of fruits, vegetables as well as decrease the intake of candy, and sweetened beverages, and increase the amount of time spent in moderate-to-vigorous physical activity and decrease sedentary behaviors (secondary outcomes) in healthy preschool aged Swedish children. If the MINISTOP app is effective, it has the potential to be incorporated into the child health care to aid in counteracting overweight and obesity.

Arm Intervention/treatment
Experimental: Mobile phone based intervention
The intervention in the present study is a web- and mobile phone based intervention aiming to develop healthy lifestyle behaviors regarding physical activity and dietary habits in 4-year-olds. The intervention will be delivered to the parents and it is available to the parents during six months.
Behavioral: Mobile phone based intervention
Parents in the intervention group receive a six month mHealth program (the MINISTOP app) based on social cognitive theory with strategies to change unhealthy diet and physical activity behaviors. The program includes information, advice, and strategies to change unhealty behaviours and the possibility to register the child's intake of fruits, vegetables, candy, sweetened beverages, moderate-to-vigorous physical activity, and sedentary time. Feedback is then provided on reported variables. In addition, the parents are able to ask questions through the app to a dietician and a psychologist.

No Intervention: Control
The control group receive a pamphlet on healthy eating and physical activity in pre-school children based on the existing guidelines. The information is similar to what parents receive from the Swedish child healthcare system

Primary Outcome Measures :
  1. Body fat [ Time Frame: At the end of the intervention and at a six month follow-up ]
    Fat mass index, FMI

Secondary Outcome Measures :
  1. Diet and physical activity variables [ Time Frame: At the end of the intervention and at a six month follow-up ]
    Fruit, vegetables, candy, sweetened beverages, sedentary time and physical activity

Other Outcome Measures:
  1. Composite scores [ Time Frame: At the end of the intervention and at a six month follow-up ]
    Two scores based on the primary and secondary outcomes. The first one contains all seven outcomes (body composition, dietary variables, and physical activity variables), while the second one only includes the six secondary outcomes (dietary and physical activity variables).
