The SmartAPPetite Youth Study (I)

We are currently using SmartAPPetite in a healthy eating study with teens in Southwestern Ontario!

Background: As nutrition and health are directly linked, It is alarming that less than half of Canadians aged 12 and older eat the recommended daily servings of fruit and vegetables.  Adolescence is a critical time to intervene to promote healthy dietary behaviours because lifelong eating habits begin in childhood and diet quality tends to sharply decrease around age 14 years and remain low into adulthood. By the time adolescents reach high school they are more independent, and are making more of their own decisions about what food they eat and buy, particularly during school days.

Our primary purpose is to evaluate the effectiveness of SmartAPPetite as part of a 12-week intervention with Ontario youth. We adopt a multi-dimensional approach to assess the impact of the smartphone intervention on three key dimensions of dietary behaviours among youth (aged 13-18 years): (1) increasing knowledge about healthy foods (‘food literacy’), (2) encouraging healthier food purchasing (‘food purchasing’), and (3) improving diet quality (‘diet quality’). Our central hypothesis is that increased use of our smartphone intervention will result in greater food literacy, positive shifts in food purchasing habits, and improvement in overall diet quality. Identifying effective interventions which improve dietary behaviours of youth is vital to lowering their risk of diet-related issues now and in the future.  This study has been approved by Non-Medical Research Ethics Board of the University of Western Ontario.
