1. Introduction

Childhood obesity is a critical public health concern that has become increasingly prevalent, posing significant risks for chronic physical and mental health conditions [1]. This complex condition is influenced by an interplay of genetic, environmental, and behavioral factors, with emerging research highlighting the substantial impact of psychological health on a child’s risk of developing obesity [2]. The present study aims to dissect this intricate relationship by examining psychological predictors of childhood obesity, with a unique focus on how these factors interact across different developmental stages.

The psychological landscape of childhood obesity is nuanced, with various factors such as self-esteem, body image, and emotional regulation playing critical roles in children’s eating behaviors and physical activity levels [3]. However, despite the known associations between psychological distress and obesity, there is a lack of research systematically analyzing these factors through the developmental trajectory of childhood [4]. This research gap underscores the need for a study that not only identifies psychological predictors of obesity but also understands how they manifest and evolve from early childhood to adolescence.

Accordingly, this study is designed to fill the existing gap by investigating the psychological determinants of obesity in a developmental context. The objectives are to delineate the psychological characteristics that correlate with obesity and to track these associations through the critical stages of child development. Such an approach is critical for developing age-appropriate interventions and could have far-reaching implications for pediatric health care [5].

The literature points to a bidirectional relationship between obesity and psychological health, with obesity increasing the risk of psychological issues and vice versa [6]. Our study draws from this existing knowledge base, aiming to expand on it by using longitudinal data to trace the progression of psychological factors and their influence on body weight throughout childhood. This longitudinal aspect is vital, as it allows for the observation of how early psychological patterns may predict later obesity, potentially offering new insights into critical periods for intervention [7].

Psychological factors such as stress, anxiety, and depression have been shown to contribute to the development of obesity, often through mechanisms like emotional eating and reduced physical activity [8]. Yet, the impact of these factors may vary by developmental stage due to the evolving cognitive, emotional, and social capacities of children as they grow [9]. Recognizing these developmental differences is essential for tailoring interventions that are developmentally appropriate and thus more likely to be effective.

In addressing these issues, the study utilizes a bioinformatic approach to analyze complex datasets, applying advanced statistical methods to unravel the relationships between psychological health and obesity across different ages [10]. By situating the research within the broader context of bioinformatics and public health, this study not only seeks to elucidate the psychological aspects of childhood obesity but also to offer a data-driven foundation for future interventions [11]. The expected outcomes include the identification of psychological markers that could serve as targets for early prevention efforts, thus contributing to the overarching goal of reducing the prevalence and impact of childhood obesity [12].

In sum, this introduction lays the groundwork for a comprehensive analysis of the psychological determinants of childhood obesity, viewed through the lens of developmental stages. The findings from this research are anticipated to provide valuable insights for healthcare professionals and policymakers, informing strategies to combat the childhood obesity epidemic with a heightened awareness of the psychological dimensions involved [13].

The escalating issue of childhood obesity extends beyond individual choices, deeply influenced by environmental factors. This research suggests that psychological factors such as Affect Dysregulation and attachment styles play a pivotal role in determining the risk of obesity in children. It aims to explore these psychological aspects and to uncover their significant, yet often overlooked, impact on child health.

Affect Dysregulation, referring to the ability to regulate emotional responses, can indirectly influence children’s eating habits and stress management, which are closely linked to weight gain. Similarly, issues related to attachment anxiety and avoidance could lead to unhealthy eating behaviors and lifestyle choices in children. These psychological factors are believed to have varying effects throughout different stages of childhood and adolescence.

The study utilizes advanced bioinformatics tools to analyze complex datasets that include psychological evaluations and biometric measurements. This method helps identify patterns and correlations not easily detected through conventional statistical analysis. By applying bioinformatics, the research aims to offer a comprehensive perspective on how psychological health impacts and possibly forecasts obesity risk in children.

By bridging psychological constructs with physical health outcomes, the research is positioned to offer new perspectives on the prevention and management of childhood obesity. It stands to inform intervention strategies that can be implemented by healthcare professionals, targeting not just the children in clinical settings but also supporting parents in cultivating a home environment conducive to psychological and physical well-being.

2. Materials and Methods

This is an ongoing cross-sectional study of a pediatric clinical population conducted by the Child and Adolescent Psychiatric Department in collaboration with the Endocrinology Outpatient Clinic and the Pediatric Clinic of Penteli General Children’s Hospital. This study explored the links between psychological well-being and body weight among a diverse cohort of children aged 5–16 years. Our participants were divided into two groups based on their Body Mass Index (BMI): one consisting of overweight and obese children (experimental group) and the other comprising children with a BMI within the normal range (control group). Recruitment was conducted across hospital outpatient and inpatient settings to ensure representation across a broad demographic and health spectrum.

Before their participation, detailed information about the study’s aims and procedures was provided to both the children and their guardians by our research team. This briefing highlighted the investigation’s focus on the interconnections between psychological factors and body weight. Ethical adherence was a cornerstone of our methodology, with informed consent and child assent obtained in alignment with established ethical standards. Precise measurements of height, weight, and BMI complemented comprehensive documentation of each participant’s medical history.

To delve deeper into the psychological landscape, participants were asked to complete a sequence of self-report questionnaires. These tools were selected for their robustness in assessing critical psychological dimensions:

• Strengths and Difficulties Questionnaire (SDQ) by Goodman R (1997), which provides insight into emotional and behavioral problems. (Emotional Problems Scale, Conduct Problems Scale, Hyperactivity Scale, Peer Problems Scale, Prosocial Scale, Total Difficulties score, Externalizing and Internalizing Scores) [14].
• The Adolescent Anxiety and Avoidant Attachment Inventory (AAAAI) by Moretti (2015) examines the nuances of adolescent attachment (attachment anxiety, attachment avoidance) [15].
• The Affect Regulation Checklist (ARC) by Moretti (2003) focuses on Affect Dysregulation and its roles in behavior (Affect Dysregulation, Affect Suppression, Adaptive Reflection) [16].

These instruments allowed for a multifaceted assessment of attachment quality, emotional regulation, and emotional or behavioral issues. By integrating these psychological constructs with biometric data, our study was poised to perform an in-depth analysis of the potential contributions of these factors to increased body weight among pediatric populations.

To address potential concerns related to the use of self-report questionnaires among participants across diverse developmental stages (8–10, 11–12, and 12–16 years), our study implemented specific methodological safeguards. Recognizing the critical challenge of ensuring accurate comprehension among younger cohorts, the questionnaires were carefully designed with age-appropriate wording and structured to facilitate understanding across the specified age ranges. To further mitigate risks associated with self-reporting and to enhance the reliability of our findings, a qualified specialist was made available during the administration of the questionnaires. This specialist was equipped to provide necessary clarifications tailored to the developmental level of the participants, ensuring that all questions were comprehended correctly without introducing bias. Such proactive measures underscore our commitment to methodological integrity, aiming to strengthen the validity of the responses obtained and to address potential limitations inherent in questionnaire-based research involving younger populations.

The collected data set the stage for a rigorous analysis aimed at unraveling the intricate dynamics between psychological health and obesity in children and adolescents. Through this methodological framework, our goal was to identify psychosocial markers for early intervention, potentially mitigating the risk and prevalence of childhood obesity. This approach reflects a commitment to advancing understanding in the field and contributing to the development of targeted strategies for promoting healthier outcomes in pediatric health.

2.1. Psychological Measures and BMI in Early Childhood (8–11 Years Old)

The dataset consists of 36 children, which includes 26 girls and 10 boys. Within the group, 23 children are classified as ‘Healthy’, 6 as ‘Overweight’, and 7 as ‘Obese’. The mean and standard deviation (SD) of Body Mass Index (BMI) for the ‘Healthy’ category is 16.39 ± 1.24, for the ‘Overweight’ category is 20.17 ± 1.06, and for the ‘Obese’ category is 23.29 ± 1.47. Across all categories, the overall mean BMI is 18.36 with an SD of ±3.06.

The dataset contains several variables that are associated with both psychological measures and biometric data of children aged between 8 and 11 years. The variables included in the dataset are as follows:

2.1.1. Psychological Metrics

• Affect Dysregulation Score

This score quantifies a child’s difficulty in managing emotional responses to various stimuli. High scores indicate greater challenges in emotional regulation, potentially leading to adverse reactions in stressful situations or difficulties in calming down after an emotional event. Affect Dysregulation is associated with a variety of mental health issues and can impact physical health and behavior, including eating habits and activity levels [17].

2.

Affect Suppression Score

This reflects the extent to which individuals consciously attempt to suppress their emotional expressions. Higher scores suggest a greater tendency toward hiding or inhibiting emotional displays, which can be a coping strategy to manage social interactions but may also lead to psychological distress and physical health problems if overused [18].

3.

Adaptive Reflection Score

This measures the ability to reflect on and adaptively manage one’s emotions and thoughts. This involves a more mindful approach to dealing with emotional experiences, promoting better emotional intelligence, problem-solving, and coping strategies. High scores indicate a healthier emotional processing style that can mitigate stress-related impacts on health and behavior [19].

2.1.2. Biometric and Demographic Data

• BMI Category: This categorizes the child’s weight status based on BMI calculations, divided into “Healthy”, “Overweight”, and “Obese” categories according to standardized pediatric BMI percentiles [20]. This source provides guidelines for interpreting BMI in children and adolescents, defining the thresholds for various weight statuses categories.
• BMI (Body Mass Index): A numerical value calculated from a child’s weight and height, which provides a reliable indicator of body fatness for most children and adolescents. BMI is used to screen for weight categories that may lead to health problems but are not indicative of the body fatness or health of an individual [21].
• BMI Percentile: This represents the child’s BMI relative to peers of the same age and sex, providing a percentile ranking that indicates the distribution of BMI in a reference population. This helps in understanding whether a child is within the expected range of body weight for their age group [22]. This document details the methodology behind the growth charts used to determine BMI percentiles for children and adolescents.
• Gender: This indicates the biological sex of the child (male or female). This demographic variable is crucial for interpreting BMI percentiles, which vary by gender, and can also be relevant in the analysis of psychological measures due to differences in emotional expression and regulation across genders [23].

These detailed attribute descriptions, grounded in psychological and biometric research, provide a comprehensive understanding of the dataset’s variables. The population represented in this dataset comprises children in the pre-adolescent developmental stage, a critical period where psychological and physical health patterns begin to emerge and solidify. These data could be used to explore the relationships between psychological well-being and obesity risk in children.

This dataset allows for the analysis of how psychological factors related to obesity during this developmental stage and could be instrumental in identifying early predictors of obesity. It may also help in understanding how emotional regulation skills are associated with weight status in children. For a more complete methodology, additional details about how the scores were obtained, the sample size, the geographical location, and the socio-economic background of the participants would also be necessary.

The dataset for children aged 8–11 years old encompasses a variety of psychological and biometric measures, collected through questionnaires. This data subset specifically aims to investigate the interplay between psychological well-being and physical health, as indicated by Body Mass Index (BMI) categories and percentiles, across 36 participants.

Numerically, the dataset details scores on Affect Dysregulation and Suppression, as well as Adaptive Reflection abilities. On average, children exhibit a moderate level of Affect Dysregulation (mean = 2.65, SD = 0.89) and Suppression (mean = 2.35, SD = 0.82), with Adaptive Reflection also showing a moderate mean score of 3.20 (SD = 0.87). The BMI values range from 13.5 to 26.1, with an average BMI of 18.36 (SD = 3.10), reflecting a broad spectrum of body weights. The BMI percentiles, ranging from 6 to 98.3, with a mean of 62.65 (SD = 29.17), further contextualizing the children’s BMI concerning age and gender norms.

Categorically, the dataset reveals ‘Healthy’ as the predominant BMI Category, represented by 23 of the 36 children, indicating a majority within normal weight parameters for their age group. Gender distribution within this cohort leans towards females, comprising 26 out of 36 participants.

2.1.3. Methodological Approach

In the present study, we analyzed the data collected from questionnaires filled out by children aged 8–11. These questionnaires encompassed a range of psychological measures, including Affect Dysregulation score, Affect Suppression score, and Adaptive Reflection. Alongside these psychological metrics, data on the children’s Body Mass Index (BMI) categories, specific BMI values, and BMI percentiles were collected. The BMI categories were encoded into numerical values for analytical purposes: Healthy (0), Overweight (1), and Obese (2). The calculation of Body Mass Index (BMI) adhered to established formulas, which take into account the child’s weight and height. Subsequently, the derived BMI was contextualized using a percentile growth chart, which benchmarks an individual’s BMI against population standards adjusted for age and sex. This comparison enabled the categorization of children and adolescents into distinct weight status groups based on percentile ranges: a ‘Healthy weight’ classification corresponds to a BMI between the 5th and less than the 85th percentile, ‘Overweight’ is assigned for BMIs from the 85th to less than the 95th percentile, and ‘Obesity’ is designated for a BMI at or above the 95th percentile, as defined by clinical growth charts [20]. A Spearman correlation analysis was conducted to explore the relationship between children’s psychological measures and their BMI categories, aiming to uncover any significant associations that could illuminate the interplay between psychological well-being and physical health in this age group.

2.2. Navigating the Transitional Years: Psychological and Biometric Profiles in Pre-Teens (11–12 Years Old)

The dataset consists of 15 children, which includes 8 girls and 7 boys. Within the group, 7 children are classified as ‘Healthy’, 5 as ‘Overweight’, and 3 as ‘Obese’. The mean and standard deviation (SD) of Body Mass Index (BMI) for the ‘Healthy’ category is 18.99 ± 0.91, for the ‘Overweight’ category is 22.40 ± 0.92, and for the ‘Obese’ category is 31.43 ± 4.00. Across all categories, the overall mean BMI is 22.61 with an SD of ±5.06.

The dataset encompasses a variety of variables that intricately combine psychological assessments with biometric information for children aged 11 to 12 years. This comprehensive collection of data includes the following key elements:

2.2.1. Psychological Metrics

Apart from the Affect Dysregulation, Affect Suppression, and Adaptive Reflection scores that are described in Section 2.1.1, we also evaluated the following metrics:

• Attachment Anxiety: This quantifies the extent of a child’s apprehension about being abandoned or rejected by attachment figures. Children with high levels of attachment anxiety may exhibit clinginess, neediness, or excessive seeking of reassurance, potentially affecting their ability to form healthy, independent relationships [24].
• Attachment Avoidance: This assesses the extent to which a child distances themselves from emotional closeness and interdependence in relationships. Avoidant attachments can manifest as a preference for solitude, difficulty in trusting others, and a reluctance to express needs or seek comfort [25].
• Emotional Problems Scale: This identifies the prevalence and intensity of internalizing emotional issues, including symptoms of anxiety, depression, and mood dysregulation. Recognizing these problems early can lead to timely interventions that may prevent the development of more serious mental health conditions [26].
• Conduct Problems Scale: This evaluates the presence of externalizing behavioral problems, such as aggression, defiance, and antisocial behavior. This scale helps identify children who may benefit from behavioral interventions to improve social functioning and prevent escalation into more severe conduct disorders [27].
• Hyperactivity Scale: This measures signs of excessive activity, impulsivity, and difficulty maintaining attention. Hyperactivity and attentional challenges are characteristic of ADHD but can also occur in other contexts. Addressing these symptoms can improve academic performance and social interactions [28].
• Peer Problems: This scores the extent of difficulties a child encounters in forming and maintaining peer relationships. Challenges in this area can impact self-esteem, social skills development, and overall well-being, highlighting the importance of supportive interventions [29].
• Prosocial Scale: This assesses the frequency and quality of positive, altruistic behaviors directed toward others, such as sharing, helping, and showing concern. Prosocial behavior is linked to social acceptance, relationship building, and emotional well-being [30].
• Total Difficulty Score: This provides an overall assessment of a child’s emotional and behavioral challenges, integrating data across various domains. This comprehensive score can guide clinicians, educators, and parents in understanding the child’s needs and planning appropriate support or interventions [14].
• Externalizing Score: This highlights behaviors that are outwardly directed and potentially disruptive, including aggressive actions and defiance. Identifying these behaviors early allows for targeted interventions that can help manage these tendencies and support positive social interactions [31].
• Internalizing Score: This focuses on inwardly directed behaviors and emotions, such as withdrawal, anxiety, and depressive symptoms, offering insights into the child’s internal emotional state and potential need for psychological support [32].

2.2.2. Biometric and Demographic Data

Please refer to Section 2.1.2 for a detailed overview of the biometric and demographic data, including BMI Category, BMI, and BMI percentile. The criteria and methodologies outlined in that section apply equally to this age group, providing a consistent basis for evaluating weight status and its potential health implications across different developmental stages.

The dataset for children aged 11–12 years provides a detailed examination of various psychological measures, biometric data, and BMI measurements. Numerically, the dataset encompasses 15 entries, with measures such as Affect Dysregulation score and Affect Suppression score averaging at 2.27 and 2.48, respectively, indicating a range of emotional regulation capabilities among the children.

The biometric data revealed an average BMI of 22.8, with a BMI percentile mean of 73.06, suggesting a healthy weight status for the majority but also indicating the presence of overweight and obese children in the cohort.

Categorically, the dataset was almost evenly split between genders, with a slight majority of male participants. The BMI Category distribution showed that most children were classified as healthy, with fewer instances of being overweight and obese.

This detailed dataset offers a nuanced view of the psychological and biometric profiles of children above 12 years of age, highlighting the interplay between mental health, social functioning, and physical health status. These findings underscore the importance of considering a wide range of factors when assessing the well-being of adolescents, pointing towards the need for holistic approaches to their health and development.

This dataset captures critical psychological and physical health variables during a pivotal developmental stage. The included psychological assessments cover a range of emotional and behavioral domains, which can be instrumental in understanding the multifaceted nature of childhood obesity. The attachment styles may provide insights into the children’s interpersonal relationships and how these might affect or be affected by their weight status.

3. Results

This section delves into the intricate relationships between psychological health and obesity across different developmental stages, employing bioinformatics techniques for data analysis.

3.1. Analysis in Early Childhood (Ages 8–11)

In the cohort of children aged 8–11, our Spearman correlation analysis examined the relationship between psychological well-being and BMI categories. Across the board for all three psychological measures under study, the analysis yielded negative correlations. Specifically, the Affect Dysregulation score negatively correlated with the BMI Category Code, displaying a coefficient of –0.083. This suggests a slight inverse relationship, where higher dysregulation scores may be marginally associated with lower BMI categories. The Affect Suppression score showed a more marked negative correlation at −0.127, insinuating that greater Affect Suppression could correlate with lower BMI categories. Similarly, Adaptive Reflection presented a negative correlation with a coefficient of −0.106, indicating that children with better Adaptive Reflection abilities might relate to healthier BMI categories.

These correlations were not statistically significant, with p-values spanning from 0.461 to 0.630, suggesting that the observed relationships may not be robust within the current sample. A heatmap was constructed to visually represent these findings (Figure 1), elucidating the direction and degree of associations among the variables studied. The intensity of the colors on the heatmap corresponds to the strength of the correlation, with cooler tones reflecting negative correlations. Notably, this visual tool underscores a modest negative correlation between Adaptive Reflection and the BMI Category Code (r = −0.11), pointing to the potential for children who are more reflectively adaptive to fall into lower BMI categories. Conversely, the Affect Suppression score’s weak negative correlation with the BMI Category Code (r = −0.13) signals a negligible association with BMI categories.

While these findings do not indicate strong evidence for a significant relationship between the psychological measures examined and BMI categories, they nevertheless hint at a pattern where emotional and cognitive processing may be linked with body weight classification. The consistently negative correlation coefficients, although statistically non-significant, suggest the need for further investigation into how emotional regulation and self-reflective capacities interact with obesity risk factors. This potential association could offer a deeper understanding of the multifaceted influences on childhood obesity and emphasize the importance of addressing psychological well-being in weight management strategies for children.

The pattern indicated by the negative correlations, though not confirmed by this study, raises interesting questions about the relationship between a child’s emotional health and their BMI Category. It suggests an avenue for future research where the role of psychological factors in physical health outcomes can be explored more comprehensively. Considering the formative nature of early childhood in setting the stage for lifelong habits and health, these preliminary indications reinforce the value of incorporating psychological evaluations into comprehensive health assessments for children. This integrated approach, acknowledging both mental and physical aspects of health, may lead to more personalized, effective, and empathetic interventions in the management and prevention of obesity in young children.

Figure 2 presents a comparative visualization of the average psychological scores across BMI categories for children aged 8–11. The bar graphs depict a trend where the Affect Dysregulation and Affect Suppression scores do not vary significantly across the BMI categories. However, the Adaptive Reflection scores show a slight decrease from the Healthy to Overweight and Obese categories. The graph indicates that while children’s ability to regulate and suppress affect might not differ markedly with their BMI status, their Adaptive Reflection abilities may be inversely related to higher BMI categories. This pattern suggests that children who are overweight or obese might experience challenges in effectively reflecting on and adapting to situations, which is an aspect worth exploring further in the context of obesity interventions.

3.2. Insights into Pre-Adolescence (Ages 11–12)

The analysis delved into the intricate connections between psychological measures and BMI categories among pre-adolescents aged 11–12. Our findings revealed a spectrum of correlation strengths, shedding light on how various psychological aspects may influence or reflect obesity risk in children. Notably, certain psychological factors such as attachment avoidance (−0.403) and Peer Problems (0.437) demonstrated noteworthy correlations with BMI categories. These results suggest a significant link, indicating that children experiencing difficulties in these areas might be at an increased risk of obesity. Additionally, the Emotional Problems Scale (0.398) and Internalizing score (0.416) exhibited strong correlations, pointing towards a potential association between emotional distress, internalizing behaviors, and variations in BMI.

Conversely, certain measures, like Adaptive Reflection (−0.179) and Prosocial Scale (−0.135), showed negative correlations. This pattern hints at an interesting dynamic: higher capabilities in reflective thinking and prosocial behavior might correlate with healthier BMI categories, suggesting that these psychological strengths could play a protective role against obesity.

Our comprehensive analysis extended to examining the interrelationships between a broad set of psychological variables and BMI categories, as visually represented in our heatmap (Figure 3). This visual aid highlights the Spearman correlation coefficients, offering a direct insight into the complex web of associations. The heatmap’s color intensity variation—ranging from negative to positive correlations—emphasizes the strength of these relationships, facilitating a deeper understanding of how psychological factors intertwine with BMI categorizations.

Despite the intriguing correlations observed, it is crucial to note that none reached statistical significance, with p-values ranging from 0.103 to 0.880. This outcome accentuates the complex interplay between psychological factors and BMI, suggesting a nuanced relationship that warrants further investigation. Particularly, the varied correlation strengths observed with the BMI Category Code underscore the multifaceted nature of obesity’s psychological underpinnings. Our analysis, especially the significant negative correlation noted between Adaptive Reflection and Affect Suppression score, underscores the importance of emotional processing skills in childhood development and health.

The lack of statistically significant correlations should not detract from the importance of these findings. Instead, it underscores the critical need for a multifaceted approach to addressing childhood obesity, one that incorporates a broad spectrum of psychological influences. The intricate relationships highlighted by our heatmap reinforce the necessity of considering psychological factors in the development of interventions aimed at combating obesity. By acknowledging the complex interactions that shape physical health outcomes, we can move towards more comprehensive, effective strategies that address the psychological and the physical aspects of obesity in children.

In Figure 4, we present a series of bar graphs that detail the average scores of twelve psychological measures as stratified by BMI Category for the children aged 11–12 in our study. Notably, the bar graphs illustrate that children with an ‘Obese’ BMI Category tend to have higher average scores on the Conduct Problems Scale, and Hyperactivity Scale and Total Difficulty score and Externalizing score, which may suggest a link between behavioral challenges and increased BMI. In contrast, the ‘Healthy’ BMI Category is associated with higher scores on the Adaptive Reflection and Prosocial Scales, potentially indicating better emotional regulation and social behaviors in children within normal weight ranges. These visual trends underscore the necessity of a multifaceted approach to childhood obesity that considers not only physical but also psychological dimensions. The differences in average scores across BMI categories emphasize the interrelated nature of mental health and obesity, hinting at the complex causative pathways that require further research and comprehensive intervention strategies.

This figure displays the mean scores of various psychological measures for children aged 11–12, categorized by BMI status. Each bar graph denotes the average score for a specific psychological construct, with comparisons drawn among children classified as ‘Healthy’, ‘Overweight’, and ‘Obese’. The visualized data underscore the potential links between psychological well-being and BMI categories, indicating focal points for targeted interventions. The bar graphs are annotated with the number of participants in each category, providing a clear and quantifiable reference for the depicted mean scores.

3.3. Adolescent Analysis (above 12 Years)

Our analysis revealed varied correlations between psychological measures and BMI categories. Notably, the Affect Dysregulation score (−0.281) and Affect Suppression score (−0.191) were negatively correlated with BMI categories, suggesting a decrease in these psychological problems as the BMI Category increases. Conversely, the Peer Problems (0.210) and Internalizing score (0.138) showed positive correlations, indicating an increase in these issues with higher BMI categories. The Adaptive Reflection (0.085) and Total Difficulty score (0.092) also displayed positive but weak correlations with BMI categories. In Figure 5, we present a heatmap of Spearman correlation coefficients that provides a visual summary of the relationships between a range of psychological variables and BMI Category Codes in children above the age of 12. The heatmap illustrates both the magnitude and the direction of correlations, with warmer colors (red) representing stronger positive correlations and cooler colors (blue), signifying stronger negative correlations. For instance, the scale of Emotional Problems shows a notable positive correlation with the BMI Category Code, suggesting that children with higher scores in emotional problems tend to have a higher BMI Category. In contrast, variables such as Affect Dysregulation and Internalizing scores exhibit negative correlations with the BMI Category Code, indicating an inverse relationship.
