简要总结
Overweight and obesity in preschool children is more and more common and predicts overweight in later childhood and adulthood. A healthy eating pattern with many vegetables decreases the risk to develop overweight. As many food preferences are learned in the first years of life, teaching children to like vegetables from the very start of eating solid foods is essential. Starting baby's first bites of solid foods with vegetables instead of more sweet tastes like fruits may promote vegetable liking. Also, it is important that parents know how to feed their children: e.g., paying attention to whether the child is hungry or full is essential, as is not pressuring them to eat. What is yet unknown is which of these two are more important to promote, to facilitate vegetable liking in young children. Is starting with vegetables most important, or educating parents on their feeding-techniques? And is a combination of both most effective? This study tests which of three interventions is most effective to promote vegetable intake and liking in children up until the age of 3 years: a) a focus on the 'what' (starting with vegetables); b) a focus on the 'how' (listen to your child's cues while feeding); c) a focus on both the 'what' and the 'how'. These three groups will be compared to a control group receiving no advice on how to introduce solid foods on children's vegetable intake and liking.
详细描述
The weaning period in infancy is an important time for introducing healthy eating patterns that include vegetables to protect children against the development of overweight. There is evidence that it is important what weaning infants are offered: starting exclusively with vegetables is more successful for the promotion of vegetable acceptance than starting with fruits. There is also evidence that it is important how infants are weaned: responsive feeding characterised by sensitive responses to infant cues during feeding fosters healthy eating. However, the what and the how of infant weaning have never been experimentally tested in the same study to determine their relative importance for fostering vegetable acceptance, nor have they been combined to test whether a focus on both may be superior to each approach separately. This study employs a randomised controlled design testing the effectiveness of (a) a focus on the what in weaning, i.e., a vegetable-exposure intervention; (b) a focus on the how in weaning, i.e., an intervention to enhance responsive feeding; (c) a combined focus on what and how in weaning in an integrated intervention; (d) an attention-control group. Vegetable acceptance will be measured before and directly after the interventions when the child is 18 months of age, and when the child is 24 and 36 months of age. The proposed study is based on a unique integration of expert knowledge from the field of nutrition and the field of parenting, which will provide new insights into the mechanisms underlying the development of vegetable acceptance in infants, and ultimately the prevention of overweight.

结局指标
主要结局
Change in vegetable liking
时间窗: Measured at child age of 4-6 months (prior to intervention), 18 months (directly after intervention) and at child age of 24 and 36 months (6 and 18 months follow-up)
Liking of vegetables as measured by questionnaire (Barends et al., 2013)
Child self-regulation of energy intake
时间窗: Measured at child age of 18 months
Measured experimentally; protocol designed for this study. In essence, children eat a meal at home until they are full, and after a short break are offered a variety of snacks. How much of the snacks they eat is a measure of child self-regulation of energy intake
Change in vegetable intake
时间窗: Measured at child age of 4-6 months (prior to intervention), 18 months (directly after intervention) and at child age of 24 and 36 months (6 and 18 months follow-up)
Intake of vegetables as measured by 3 days of 24hr recall electronic diaries (using the Compl-eat system developed at Wageningen University)
Change in child self-regulation of energy intake
时间窗: Measured at child age of 4-6 months (prior to intervention), 18 months (directly after intervention) and at child age of 24 and 36 months (6 and 18 months follow-up)
Measured by the Child Eating Behavior Questionnaire
次要结局
- Change in child anthropometrics(Measured at child age of 4-6 months (prior to intervention), 18 months (directly after intervention) and at child age of 24 and 36 months (6 and 18 months follow-up))
- Change in observed maternal feeding style(Measured at child age of 4-6 months (prior to intervention), 18 months (directly after intervention) and at child age of 24 and 36 months (6 and 18 months follow-up))
- Change in child eating behavior(Measured at child age of 4-6 months (prior to intervention), 18 months (directly after intervention) and at child age of 24 and 36 months (6 and 18 months follow-up))
- Change in self-reported maternal feeding style(Measured at child age of 4-6 months (prior to intervention), 18 months (directly after intervention) and at child age of 24 and 36 months (6 and 18 months follow-up))
