Mothers improve their daughters vegetable intake : A randomized controlled trial

The increasing prevalence of childhood overweight makes children an important target for health promotion programmes. An intervention was designed for mothers to provide more vegetables to their daughters’ diet. A randomized controlled trial compared a self-regulation condition with a control condition in 155 mothers aged 25–50 years. Dependent variable was children’s (aged 6–11 years) vegetable consumption which was reported by their mothers at three points in time. After baseline (Time 1), the intervention group received theory-based instructional leaflets to promote self-regulatory skills for providing a healthy nutrition for children. Changes were assessed after two weeks (Time 2) and at three-month follow-up (Time 3). The self-regulation intervention in mothers led to an increase in vegetable intake among their daughters at Time 2 but not at Time 3. However, maintenance of vegetable consumption at Time 3 was mediated by the amount of vegetable intake at Time 2. Engaging mothers in self-regulatory health promotion programmes may be a feasible strategy to facilitate more vegetable intake among their daughters.
