Brief Summary

This explanatory sequential mixed-methods study evaluated a six-week Piaget-based nutrition education programme for preschool children. Seven public preschools were randomized at the school level to an intervention condition (three preschools) or a usual-curriculum control condition (four preschools). The intervention consisted of six weekly, approximately 30-minute, developmentally tailored sessions delivered to groups of children in their usual classrooms. Mothers completed measures of children's food consumption frequency, nutrition behavior, and eating behavior before and immediately after the programme. Following the quantitative phase, three focus groups with 18 mothers from intervention preschools explored perceived changes and helped interpret the quantitative patterns. Because preschool identifiers were not retained in the final analytical dataset, the reported child-level analyses did not adjust for clustering and are interpreted as exploratory.

Outcome Measures

Primary Outcomes (3)

• Change from baseline in food consumption frequency

  In the Food Consumption Frequency Questionnaire, there are foods that include 7 food groups (dairy group, meat group, vegetable group, fruit group, grain group, oil/margarine group, and sweet group) aimed at determining the child's food consumption status (Güneş et al., 2016). Food consumption frequency is recorded in nine different categories (\>6/day, 4-5/day, 2-3/day, 1/day, 5-6/week, 2-4/week, 1/week, 1-3/month, 1-none/month). The Food Consumption Frequency Questionnaire specific to Turkish children was developed by Güneş and colleagues in 2016. The form includes not only food items but also commonly used ingredients in Turkish cuisine. During the development phase of the form, a food atlas containing the most frequently consumed foods, beverages, and some Turkish dishes was used. Results are reported by food item or food group; the questionnaire does not yield a single total score.

  Baseline and immediately after completion of the six-week intervention

• Change in Nutrition Behavior Scale (NBS) Score

  In determining eating behaviors, the Nutrition Behavior Scale developed by Edmundson et al. (1996) and adapted for Turkish children by Öztürk (2010) was used. The scale consists of fourteen different items, each containing two different food items-low-fat, high-fat, salty, and unsalted-depicted in pictures and presented as choices, to determine children's food consumption. Students are asked to indicate which of the two comparable food items in each question item they eat more. The scale items receive a value of -1 for unhealthy food and +1 for healthy food. The total score ranges from -14 to +14. A high total score on the scale indicates a healthy eating habit. The reliability of the scale has been reported as r=0.76 (Öztürk, 2010).

  Baseline and immediately after completion of the six-week intervention

• Change in Children's Eating Behavior Questionnaire (CEBQ) Subscale Scores

  Developed by Wardle et al. (2001), the Children's Eating Behaviour Questionnaire (CEBQ) is a 35-item parent-reported instrument that assesses children's eating behaviours on a five-point Likert scale ranging from 1 (never) to 5 (always). It comprises eight subscales: Food Responsiveness, Emotional Overeating, Enjoyment of Food, Desire to Drink, Satiety Responsiveness, Slowness in Eating, Emotional Undereating, and Food Fussiness. Each subscale is scored separately, with higher scores indicating a greater level of the behaviour represented by that subscale. The original instrument demonstrated an eight-factor structure, with Cronbach's alpha coefficients ranging from 0.74 to 0.91. The Turkish validity and reliability study was conducted by Yılmaz et al. (2011).

Piaget-Based Nutrition Education

EXPERIMENTAL

Children attending the three intervention preschools received the six-week Piaget-based nutrition education programme in their usual classrooms. A total of 138 mother-child dyads were allocated to intervention preschools; 130 children received at least part of the programme, and 127 dyads were included in the reported per-protocol analysis.

Behavioral: Piaget-Based Nutrition Education Program

Usual Preschool Curriculum

NO INTERVENTION

Children attending the four control preschools continued their usual preschool curriculum and did not receive the Piaget-based nutrition education programme during the study period. A total of 130 mother-child dyads were allocated to control preschools, and 111 dyads were included in the reported analysis.

Interventions

Piaget-Based Nutrition Education Program BEHAVIORAL

The researcher delivered six weekly sessions, each lasting approximately 30 minutes, to groups of 8-15 preschool children in their usual classrooms. The programme was tailored to the preoperational stage of cognitive development and used simple language, concrete classification, play, pictures, coloring, cartoons, songs, sensory exploration, and fruit-yogurt preparation. Sessions addressed food groups; fruits; vegetables; energy- and growth-supporting foods; milk and dental health; and foods to be consumed every day or occasionally.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Masking Details: Because of the nature of the educational intervention, children, mothers, and the researcher delivering the intervention were aware of group assignment. Blinding of outcome assessors and data analysts was not documented.
• Purpose: PREVENTION
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Lecturer Doctor

Model Details: Seven public preschools were randomized at the preschool (cluster) level to either the intervention condition (three preschools) or the control condition (four preschools) using a random-number table. All participating children within each preschool received the condition assigned to that preschool. Preschools were the units of randomization, and children were the units of observation.
