Encouraging direction, but not yet definitive.
This prospective observational study of 325 children aged 6–14 years demonstrates significant associations between obesity and elevated cortisol, TSH, HOMA-IR, and fasting insulin, alongside reduced free T4, after adjustment for age and gender. The findings suggest childhood obesity is linked to hormonal and metabolic alterations, but the observational design does not establish causality and cannot distinguish primary pathology from adaptive responses.
Prospective observational study with three cross-sectional BMI groups. 325 children aged 6 to 14 years at a tertiary care teaching hospital in north India; stratified by BMI percentile into normal weight, overweight, and obese groups.. Compared with: Normal-weight children (comparison group within observational cohort). n = 325. Tertiary care teaching hospital in north India.
Obese children showed markedly elevated cortisol, TSH, HOMA-IR, and fasting insulin compared to normal-weight children (p<0.05) Obese children demonstrated reduced free T4 levels compared to normal-weight children (p<0.05) Multivariate linear regression controlling for age and gender confirmed BMI was significantly associated with insulin resistance markers and thyroid hormone levels

Clinicians should consider screening for hormonal alterations (particularly thyroid and insulin resistance markers) in obese children; however, the observational design means individual cases may differ substantially from group patterns, and causality cannot be inferred.
A prospective observational study with adequate sample size (n=325) and multivariate analysis showing associations between obesity and multiple hormonal markers in children, but lacking a comparator intervention and relying on cross-sectional associations rather than causal evidence.

Background: Hormonal alterations, may complicate the metabolic consequences linked to childhood obesity. To study the relation between pediatric obesity and hormonal abnormalities, along with the correlation between body mass index (BMI) and other metabolic and endocrine markers. Methods: A prospective observational study including 325 children aged 6 to 14 years was conducted at a tertiary care teaching hospital in north India over 30 months (January 2024 to July 2026). Individuals were classified into three categories based on their BMI percentiles for age and gender as normal weight, overweight, and obese. In addition to blood pressure and anthropometric data, fasting biochemical markers such as cortisol, free thyroxine (free T4), glucose, insulin, and thyroid-stimulating hormone (TSH) were measured. The homeostasis model assessment of insulin resistance (HOMA-IR) was calculated to determine insulin resistance. One-way analysis of variance and multivariate linear regression with age and gender adjustments were used for statistical analysis. Results: Obese children demonstrated markedly elevated levels of cortisol, TSH, HOMA-IR, and fasting insulin compared to their normal-weight counterparts, along with reduced levels of free T4 (p<0.05). A multivariate regression analysis, after controlling for age and gender, indicated that BMI was significantly associated with indicators of insulin resistance and thyroid hormone levels. Conclusions: Childhood obesity is associated with significant hormonal and metabolic alterations, suggesting early endocrine adaptations that may have metabolic implications. While these changes (particularly thyroid-related shifts) represent reversible, adaptive responses rather than primary pathology, findings highlight need for early identification and intervention to prevent potential long-term cardiometabolic risks associated with pediatric-onset obesity.
