Cardiovascular disease risk factor (CVDRF) associated waist circumference patterns in obese-prone children

Area of Science:

• Pediatrics
• Cardiology
• Obesity Research

Background:

• Childhood obesity is a growing concern with long-term health implications.
• Waist circumference (WC) is a key indicator of abdominal obesity and cardiovascular disease risk.
• Identifying children at risk early is crucial for intervention.

Purpose of the Study:

• To determine if children at high risk (HR) for obesity are more likely to have a waist circumference (WC) associated with cardiovascular disease risk factors (CVDRF-WC) compared to low-risk (LR) children.
• To assess whether CVDRF-WC status tracks over time in these children.

Main Methods:

• Prospective cohort study of 71 children aged 3-8 years, divided into LR and HR groups based on maternal prepregnancy BMI.
• HR group further classified into HR normal-weight (HRNW) and HR overweight (HROW) based on BMI.
• Children's CVDRF-WC status was assessed annually using age- and gender-specific WC cut-offs.

Main Results:

• While HR children had larger mean WC than LR children at older ages, this difference diminished after adjusting for BMI.
• HROW children were significantly more likely to have CVDRF-WC status from age 4 to 8 compared to LR and HRNW children.
• A high proportion of children maintained their CVDRF-WC status, with HROW children showing a greater tendency to transition into this category.

Conclusions:

• Overweight children born at high risk for obesity are more prone to developing a waist circumference associated with cardiovascular disease risk factors.
• While BMI influences WC, measuring WC in obese-prone children can help identify those at risk for obesity-related complications.
• Early clinical assessment of WC in at-risk youth is recommended for timely intervention.
