Gestational diabetes mellitus and size at birth modify early adiposity accretion. Evidence from the OBESO cohort.

Aim: To evaluate the association between maternal obesity, gestational diabetes (GDM), and birth size with infant fat-mass (FM) accretion from 1 to 6 months (M).

Methods: Healthy pregnant women and their term babies from the OBESO cohort were studied (1 M-3 M, n = 122; 1 M-6 M, n = 90). Registered maternal data was: pregestational body-mass-index (preBMI), GDM (2hOGTT), medications, gestational weight gain.

Development and validation of anthropometric-based fat-mass prediction equations using air displacement plethysmography in Mexican infants.

Background/objectives: Fat-mass (FM) assessment since birth using valid methodologies is crucial since excessive adiposity represents a risk factor for adverse metabolic outcomes.

Aim: To develop infant FM prediction equations using anthropometry and validate them against air-displacement plethysmography (ADP).

Subjects/methods: Clinical, anthropometric (weight, length, body-mass index -BMI-, circumferences, and skinfolds), and FM (ADP) data were collected from healthy-term infants at 1 (n = 133), 3 (n = 105), and 6 (n = 101) months enrolled in the OBESO perinatal cohort (Mexico City).

Anthropometric and clinical correlates of fat mass in healthy term infants at 6 months of age.

Background: Body composition in infancy plays a central role in the programming of metabolic diseases. Fat mass (FM) is determined by personal and environmental factors. Anthropometric measurements allow for estimations of FM in many age groups; however, correlations of these measurements with FM in early stages of life are scarcely reported.
