According to the Ecological Systems Theory, obesity risk factors for children interplay between three determinants: child characteristics, familial characteristics, and societal characteristics. Beyond genetic predispositions, behavioural patterns, such as dietary choices, exercise, and sedentary behaviour, can place a child at risk for obesity. The main aims of this study were to increase daily vegetable and fruit intake and physical activity (i.e., active playtime) and reduce sedentary behaviour and screen time among children. This study was a pilot randomised control and intervention study which recruited parents with children aged between 1 and 3 years. A total of 73 eligible participants were enrolled in the study and were randomly assigned to the intervention (n = 37) or control group (n = 36). Results show that: - intervention group had significant improvements in fruit and vegetable intake by 0.91 and 0.54 servings/day, respectively, over the course of two months. - even though children in the intervention group increased their moderate-to-vigorous physical activity, the increase was not significant compared to the control group. - there were significant improvements in comprehensive parental feeding practices. Authors conclude that empowering families through a theory-based, multicomponent eHealth intervention program is a promising approach for improving nutrition and health-related behavioural changes in young children.
