Design outcomes

Primary

MeasureTime frame
Current primary outcome measures as of 24/07/2014: 1. Assessment of recruitment (measured when recruitment closes, 2 weeks after initial recruitment email), retention and data completion rates (measured after week 18, when the trial ends) 2. Healthiness of ready meals and pizzas purchased during the intervention period (measured in weeks 1-6) 3. Healthiness of ready meals and pizzas purchased during the follow-up period (measured in weeks 7-18) Here ?healthiness? is defined using an algorithm to combine the information provided in the front of pack food labels on the purchased ready meals. Primary outcomes 2 and 3 will be adjusted for age, sex, presence of dependent children, and healthiness of ready meals and pizzas purchased in the 6 months prior to recruitment. Previous primary outcome measures: 1. Assessment of recruitment (measured when recruitment closes, 2 weeks after initial recruitment email), retention and data completion rates (measured after week 22, when the trial ends) 2. Healthiness of ready meals and pizzas purchased during the intervention period (measured in weeks 1-6) 3. Healthiness of ready meals and pizzas purchased during the follow-up period (measured in weeks 7-22) Here ?healthiness? is defined using an algorithm to combine the information provided in the front of pack food labels on the purchased ready meals.
