Official Title

Living Green and  Healthy for Teens (LiGHT)

Status

Ongoing

Overview

This trial will demonstrate whether a relatively long term use of a rigorously-designed, evidence-based, user-friendly app is able to help families with teenagers improve health behaviours of youth and have any early impact on CV risk factors. Conducting an RCT in the context of the full range of youth in the community has the potential to inform population-scale implementation as a public health tool for sustainable obesity prevention across Canada.

Study Design

Using a single-centre randomized, parallel, controlled single-blind design, 376 eligible youth-parent dyads will be allocated 1:1 to received: a) the LiGHT app system; or b) a list of links to websites providing information and tips on healthy eating and activity. They will be followed for 1 year.

Primary Endpoint

The primary endpoint will be a composite of health behaviours: the proportion of youth engaging in at least 4 of the following 7 behaviours at the 1 year point after randomization:

a) ≥60 minutes of MVPA daily

b) ≤2 hours of recreational screen time daily

c) 9-11 hours (for those ≤13 years) and 8-10 hours (for those ≥14 years) of nightly sleep

d) ≥5 fruit and vegetable servings per day

e) ≤2 sugary beverages per week

f) breakfast consumption 7 days per week

g) eating out or ordering in <1 time per week.
