Observational study finds maternal BMI and diet quality influence oxidative stress and inflammation, indicating need for tailored nutrition.

Higher levels of inflammatory and oxidative stress biomarkers were observed in overweight and obese women compared to those with normal weight.
Independent associations between maternal BMI and biomarkers like CRP and hepcidin were confirmed, highlighting significant links to diet quality.
Dietary intake varied by BMI, revealing that nutritional quality was often suboptimal relative to national guidelines, especially for key nutrients.
