PEaters Choice™: Nutrition Intervention Module for Picky Eaters

Picky eaters (PE) are defined as individuals with a lack of diversity in food intake and fear of trying new foods which generally leads to malnutrition. Globally, between 20% to 55% of children worldwide are being reported as PE. Malaysia particularly has 31.8% PE children. To date, limited comprehensive modules on dietary recommendations are designed to help parents and/or primary healthcare workers to address this issue. This study is a single-blind randomized controlled trial to evaluate the effectiveness of PEaters Choice™ designed for PE children aged three to five years, with the objective to increase the food repertoire of the children. The PEaters Choice™ is a 12-week intervention program designed for mother, father or guardian-child dyads. The dyads will be divided into two groups; Intervention and Control Group. This trial will require each group to complete a list of commonly eaten foods, Child Eating Behavior Questionnaires, and a set of anthropometric data. Intervention groups will then follow three phases of the intervention program. This module suits primary healthcare settings, helping parents or guardians strategize meal planning, hence lowering the risk of malnutrition among PE children.

The study will be conducted at the UKM Specialist Children's Hospital (HPKK UKM) in Kuala Lumpur to simulate real-life situations for this module. All briefings, therapies, and activities will be conducted in this setting. Considering several factors, especially subjects' commitment to attend the prescribed session, the selected area to participate in the study is a 5km radius from HPKK UKM.

The study information sheet and consent form are written in Malay, the Malaysian national language, and in the English language. The head researcher is responsible for the consent process and answering all relevant questions. However, other researchers will also assist in conveying this information from time to time. After the briefing session, mother, father or guardian will be given time to understand and ask any questions related to the study. If the parents or guardians feel it is necessary to take a longer time before making a decision, they may also take the study information form and consent form home.

Sample size calculation using the G-Power program (95% confidence interval, 80% power) found a minimum of 138 subjects required. The study sample was increased by 10%, considering the dropout factors to 154 subjects (77 people for each group).

The dyads who have consented to participate in the study will be placed in the same age nursery or kindergartens group and randomly selected to participate in intervention groups. Children in the same nursery/kindergarten will receive the same intervention. As the intervention will be conducted by the researcher, the dyads will not be informed (blinded) of their type of intervention.

The research team will manage all data. Data will be entered into the SPSS program by the researcher and reviewed by the head researcher. Questionable data will be confirmed with original forms or relevant sources. Outlier data that is deemed unreasonable will be removed and marked as missing.

Most of the questionnaires will be filled out by mothers, fathers or guardians, in ensuring they understand the questions correctly. To avoid data loss, each form will be carefully reviewed once completed by mothers, fathers or guardians. Weighing scales and stadiometers will always be calibrated using standard weights and rulers before weight and height measurements are taken. The head researcher will check 10% of the BMI calculation and nutritional status as a quality control measure.

Data will be analyzed using the SPSS program. Using mixed ANOVA, the investigators compared the list of foods eaten (food repertoire) before, during, and after the intervention between the two groups to evaluate the impact of the intervention. On the Child Eating Behavior Questionnaires, the comparison of eight primary constructs scores between the two groups was also accomplished with mixed ANOVA. A similar statistical analysis was used to assess the nutritional status of the intervention and control groups.

All data will be kept in a safe location that only the research team will have access to. Password protection will be implemented on all user computers. Once the data is no longer required for this study, it will be destroyed. After the trial ends, the data will be kept for at least three years. The trial data will be disposed of in compliance with the Malaysian Good Clinical Practice Guidelines 2018, which will be followed.

The procedure in this study will not involve any invasive process and provided only minimal risk to the subjects. Therefore, the subjects will continue participating in the study for 12 weeks. If any subject fails to attend two consecutive therapy/activity sessions and does not attend three sessions in total, the subject will be removed from the study. However, the final decision to discontinue the subject will be made after discussion with the research team members.
