Maternal obesity associated with inflammation in their children

Area of Science:

• Pediatric Health
• Maternal-Fetal Medicine
• Inflammation Research

Background:

• Maternal obesity is a growing concern with potential long-term health implications for offspring.
• Inflammatory markers and adiponectin are key indicators of metabolic and inflammatory states.

Purpose of the Study:

• To investigate the association between maternal pre-pregnancy obesity and specific inflammatory markers (TNF-α, IL-6, hs-CRP) and adiponectin in 12-year-old offspring.
• To determine if maternal obesity influences these biomarkers in children, adjusting for potential confounders.

Main Methods:

• Thirty-four children from the Infant Growth Study were assessed at age 12.
• Participants were categorized into high-risk (HR) and low-risk (LR) groups based on maternal pre-pregnancy BMI.
• Measurements included weight, height, Tanner stage, and key biomarkers.

Main Results:

• Children in the HR group showed significantly higher levels of high-sensitivity C-reactive protein (hs-CRP) compared to the LR group.
• No significant group differences were observed for tumor necrosis factor-α, interleukin-6, or adiponectin.
• The odds of HR children having detectable hs-CRP were 16 times greater than LR children, even after adjusting for BMI z-score, Tanner stage, and gender.

Conclusions:

• Maternal obesity during pregnancy is associated with an increased risk of elevated hs-CRP in offspring.
• This association remains significant even when controlling for the child's current weight status.
• Early life inflammatory profiles may be influenced by the maternal metabolic environment during gestation.
