# Relationship of nutritional behaviors and parent–child interactions with developmental domains of Iranian toddlers: a cross-sectional study

## TL;DR

This study explores how nutrition and parent-child interactions affect the development of Iranian toddlers, finding links to communication and problem-solving skills.

## Contribution

The study identifies specific developmental domains influenced by nutrition and parent-child interactions in Iranian toddlers.

## Key findings

- Most toddlers were normal in developmental domains, with gross motor skills showing the highest delay.
- Nutritional behaviors significantly correlated with problem-solving development (p=0.018).
- Parent-child interactions significantly correlated with communication development (p=0.04).

## Abstract

Health service providers closely monitor the developmental state of toddlers to identify the factors affecting this process because any defect during this period will cause irreversible damage. Therefore, this study investigated the relationship of nutritional behaviors and parent–child interactions with the developmental domains of Iranian toddlers.

This cross-sectional, descriptive-analytical study was conducted on 341 toddlers aged 12–36 months covered by comprehensive health centers in the south of Tehran in 2021–2022. The participants were selected through single-stage cluster sampling. To this end, 16 comprehensive health centers were randomly selected, and then some of the clients from each center were randomly selected as the sample. The required data were collected through the Ages and Stages Questionnaire (ASQ), the Children’s Eating Behavior Questionnaire (CEBQ), the Child-Parent Relationship Scale (CPRS), and a demographics form. They were then analyzed statistically using descriptive and inferential statistics in SPSS-21, considering a significance level of p < 0.05.

The results showed that most participants were normal in all developmental domains (communication, gross motor, fine motor, personal-social, and problem-solving), with a mean developmental delay ranging from 1.8 to 7%. The most serious problem of participants requiring medical referral was related to gross motor (7%) with a mean of 54.35 ± 7.28 followed by communication (6.5%) with a mean of 49.41 ± 9.67. The mean nutritional behavior of participants was 77.9 ± 21.7. A significant relationship was found between the nutritional behaviors of participants and the problem-solving domain of development (p = 0.018). The results also indicated a mean parent-child interaction score of 94.26 ± 12.63. There was a significant relationship between parent-child interactions and the communication area of development (p = 0.04).

Since some areas of toddler development are influenced by children’s nutritional behavior and parent-child interactions, it is necessary to train families to identify, monitor, and correct the factors affecting the development of their children. Health system officials and planners are also recommended to develop interventions to improve the nutritional behaviors of children and parent-child interactions.
