Conclusions
This study reports the real-world effectiveness of the MINISTOP 2.0 app in a population-based sample, where 24% of the children had two foreign-born parents. Overall, the intervention resulted in statistically significant lower intakes of sweet and savory treats, sweet drinks, and screen time, as well as higher PSE when compared to the control group. Altogether, these findings together with the results from our previous efficacy trial (MINISTOP 1.0) support the implementation of the MINISTOP 2.0 intervention within primary child health care at scale.
