Randomized One-Center Controlled Trial on a Comprehensive Nutritional Intervention for Children With Cerebral Palsy and ASD

The Weight-for-Age Z-Score serves as a secondary outcome measure in the study, primarily focusing on assessing changes in the study participants' weight status. Data collection involves anthropometric assessments and the utilization of reference growth charts, specifically the World Health Organization (WHO) reference charts, to record participants' weight relative to their age. This measurement employs the Z-score as the unit of measure, quantifying deviations in weight from the baseline. A positive Z-score indicates above-average weight for a given age group, while a negative Z-score indicates below-average weight, providing a valuable indicator of participants' nutritional status and growth trends over time.

The Height-for-Age Z-Score is a secondary outcome measure focused on evaluating changes in the study participants' height status. It involves anthropometric assessments and the use of WHO reference growth charts to record participants' height in relation to their age. The Z-score is the unit of measure, allowing for the quantification of height changes relative to the baseline. A positive Z-score indicates above-average height for the age group, while a negative Z-score indicates below-average height, offering a valuable indicator of participants' growth patterns and nutritional well-being over time.

The secondary outcome measure, BMI-for-age Z-Score, assesses changes in the study participants' Body Mass Index (BMI) in relation to their age. This measurement relies on deriving BMI from weight and height measurements, with comparisons made using reference growth charts provided by the World Health Organization (WHO). The Z-score is employed as the unit of measure, enabling the quantification of BMI changes relative to the baseline. A positive Z-score signifies an above-average BMI for the age group, whereas a negative Z-score indicates a below-average BMI, serving as an essential metric for tracking variations in participants' nutritional status and body composition throughout the study.

The 'Number of Social Interactions per Week with Non-Family Members' is a quantitative measure that assesses the child's weekly engagement in social interactions with individuals outside their immediate family circle. It involves tracking and recording the frequency of diverse social exchanges, such as conversations, playdates, school-related interactions, and community engagements over a one-week period. This measure is instrumental in evaluating the child's social participation, integration into broader social networks, and overall quality of life. A higher number of interactions typically indicates greater social engagement and integration, while a lower number may signal reduced social participation, highlighting areas that require attention for the child's holistic development.

Total Number of New Spoken Words per Month is a quantitative measure employed to evaluate a child's language development and communication skills over a one-month period. This measure involves systematically counting and recording the distinct words that the child effectively uses and articulates in conversations, interactions, or observations during the course of each month. Specifically, it focuses on identifying and tallying newly acquired words within the given timeframe.A higher number of newly spoken words typically indicates positive language development, reflecting effective vocabulary expansion and improved communication skills. A threshold of one new word per month is established as a meaningful indicator of progress.

Total Days of School or Kindergarten Attendance per Month is a quantitative measure used to precisely assess a child's consistent participation in a formal educational setting, such as school or kindergarten, within the span of one month.A higher total number of days attended per month reflects more consistent participation in educational settings, indicating a stronger connection to learning opportunities and educational routines. Conversely, a lower total may indicate irregular attendance or potential challenges that require attention.

The 'Number of Leisure Activities per Month' is a quantitative measure used to assess children's level of engagement in leisure and recreational pursuits over a one-month period. This measure involves systematically counting and documenting the quantity of diverse leisure activities, hobbies, or pastimes that the individual participates in during the designated month. Leisure activities encompass a wide range of choices, such as hobbies, sports, cultural events, or entertainment, selected for relaxation, enjoyment, and personal enrichment. A higher count of leisure activities often indicates a more diversified and active leisure lifestyle, potentially contributing to an enhanced overall quality of life, while a lower count may suggest limited engagement in leisure pursuits, highlighting opportunities for greater leisure satisfaction.
