Messages for Increasing Dairy Consumption
Condition: Dietary Modification
Study type: Interventional

Summary: 
      Over 35,000 Canadians, 65% of men and 72% of women aged 31-50 years fail to consume the
      recommended number of milk and milk product servings (≤2 servings per day). Given the wide
      range of health benefits associated with increased dietary intake of milk and milk products
      the objectives of this study were to conduct a prospective, 5-arm randomised controlled trial
      in order to test the effectiveness of a variety of messages for increasing milk and milk
      product consumption in men and women aged 30-50 years old. The five arms consisted of 4
      messages that contained slightly different content specifically: 1) gain-framed message
      condition, 2) loss-framed message condition, 3) self-regulatory efficacy-enhancing message
      condition, 4) gain-framed and self-regulatory efficacy-enhancing message condition and 5)
      loss-framed plus self-regulatory efficacy-enhancing message condition. It was hypothesised
      that those who receive self-regulatory efficacy-enhancing information would consume more
      dairy than those who received messages without such information. Second, those who received
      gain-framed messages would consume more dairy as compared to those who received loss-framed
      messages. Third, those who received gain-framed messages that include self-regulatory
      efficacy-enhancing information would consume the most dairy in comparison to the other four
      conditions.

Intervention type(s): Behavioral; Behavioral; Behavioral; Behavioral; Behavioral
Intervention description(s): Participants will be randomised to one of five message conditions. Each condition will receive a total of four emailed messages on four consecutive days (i.e., 1 message per day). Participants in the Gain-Framed message condition will receive message content that highlights the potential benefits of consuming milk and milk products (i.e., high protein content, stronger hair and nail etc.); Participants will be randomised to one of five message conditions. Each condition will receive a total of four emailed messages on four consecutive days (i.e., 1 message per day). Participants in the Loss-Framed message condition will receive message content that highlights the potential losses of not consuming milk and milk products (i.e., lack of essential nutrients, less calcium).; Participants will be randomised to one of five message conditions. Each condition will receive a total of four emailed messages on four consecutive days (i.e., 1 message per day). Participants in the Self-Regulatory Efficacy message condition will receive information pertaining to how to include milk and milk products within their diet. This information will come in the form of recipes, meal planning, food combining etc.; Participants will be randomised to one of five message conditions. Each condition will receive a total of four emailed messages on four consecutive days (i.e., 1 message per day). Participants in the Gain-Framed message + Self-Regulatory Efficacy condition will receive message content that highlights the potential benefits of consuming milk and milk products (i.e., high protein content, stronger hair and nail etc.) and information pertaining to how to include milk and milk products within their diet.; Participants will be randomised to one of five message conditions. Each condition will receive a total of four emailed messages on four consecutive days (i.e., 1 message per day). Participants in the Loss-Framed message + Self-Regulatory Efficacy condition will receive message content that highlights the potential losses of not consuming milk and milk products (i.e., lack of essential nutrients, less calcium) and information pertaining to how to include milk and milk products within their diet.
