Fetal development depends on maternal metabolic energy from mitochondria. We investigated the association of maternal mitochondrial function, represented by mitochondrial DNA copy number (mtDNA-CN) of venous blood, with child birth weight (BW) from 528 randomly selected mothers enrolled in the Supplementation with Multiple Micronutrients Intervention Trial (ISRCTN 34151616). Real-time quantitative PCR of archived blood specimens and regression analysis adjusting for other primary determinants of BW showed that loge mtDNA-CN was inversely associated with BW (β = -204.6, p
