Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to explore the effect maternal obesity and breastfeeding play on infant body composition. The investigators hypothesize in the first 6 months of life breast fed offspring from overweight / obese mothers will be fatter with greater trunk fat mass and accumulate fat at a greater rate than breast fed infants from normal weight mothers. Furthermore, the investigators postulate that circulating maternal milk adipocytokines will positively correlate to total fat mass at six months of age.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The objective of this study is to determine if offspring from overweight/obese non-diabetic mothers whom breastfeed have greater total fat and trunk fat mass and accumulate fat mass at a greater rate from \~ 1 month to 6 months of life compared to breastfed infants from normal weight mothers.

Specific Aim 1: Understand how maternal obesity and breast-feeding impact body composition of the offspring. Based upon the investigators preliminary data and counter to accepted dogma the hypothesis is at six months of age total fat mass, particularly in the trunk will be elevated at 6 months of age in infants whose mother was either overweight or obese vs. infants from normal weight mothers.

Specific Aim 2: Identify adipocytokines in breast milk. The postulate is breast milk from overweight and obese mothers will have greater levels of insulin, glucose, Ghrelin, IGF-1, IL-6, TNFα, high-sensitivity C-reactive protein, and lower Leptin levels than breast milk from normal weight mothers and will be correlated with offspring fat mass.
