Insights
Insulin resistance (IR) in obese children is linked to weight changes. Children without IR lost weight, while those with IR did not, suggesting IR impacts adiposity.
Area of Science:
- Pediatric Endocrinology
- Metabolic Health
- Obesity Research
Background:
- Insulin resistance (IR) is a key factor linking obesity to metabolic and cardiovascular issues.
- IR's role in weight changes, particularly in children, requires further investigation.
Purpose of the Study:
- To investigate the influence of insulin resistance (IR) on weight status in obese prepubertal children over a 1-year intervention.
Main Methods:
- Study included 44 children with IR and 42 without IR.
- Evaluated Body Mass Index standard deviation score (BMI-SDS), waist circumference (WC), and homeostasis model assessment for IR (HOMA-IR).
Main Results:
- Children without IR showed significant reductions in BMI-SDS and WC.
- IR children maintained unchanged BMI-SDS and WC; their HOMA-IR worsened.
- Baseline HOMA-IR correlated significantly with follow-up BMI and WC.
Conclusions:
- Insulin resistance appears to affect adiposity changes in obese prepubertal children.
- Further longitudinal studies are necessary to confirm the relationship between IR and weight management in childhood.
Background:
Insulin resistance (IR), a link of paramount importance between obesity and cardiovascular/metabolic complications, seems to be implicated in weight changes.
Objective:
To determine whether IR could influence weight status during a 1-year intervention program in obese prepubertal children.
Methods:
Forty-four children with IR (IR group) and 42 children without IR (NIR group) were enrolled. Body mass index standard deviation score (BMI-SDS), waist circumference (WC), and homeostasis model assessment (HOMA-IR) were evaluated.
Results:
NIR children showed a significant reduction of BMI-SDS and WC at final assessment (p = 0.009 and p = 0.001, respectively), whereas IR children presented unchanged values. HOMA-IR decreased after intervention in the NIR group (p = 0.0008), but was exacerbated in IR children (p = 0.004). A positive and significant association between HOMA-IR at baseline and BMI at follow-up was found (B ± SE = 0.87 ± 0.24, p = 0.001). HOMA-IR at baseline was also significantly associated with WC at follow-up (B ± SE = 2.12 ± 0.69, p = 0.003).
Conclusions:
IR seems to influence adiposity changes in obese prepubertal children. Further longitudinal studies are needed to verify the relationship between IR and weight loss during childhood.
