Mid-pregnancy weight gain is associated with offspring adiposity outcomes in early childhood.

Background: Gestational weight gain (GWG) has been linked to childhood obesity. However, it is unclear if the timing of weight gain influences offspring body composition. A secondary analysis of a clinical trial examined the influence of total, early, and mid-pregnancy GWG on adiposity outcomes in 186 children at birth, 1, 3, and 5 years.

Evaluation of Maternal Dietary n-3 LCPUFA Supplementation as a Primary Strategy to Reduce Offspring Obesity: Lessons From the INFAT Trial and Implications for Future Research.

Preclinical research suggests that early exposure to LCPUFAs is associated with offspring health outcomes, although evidence in humans is rather unclear. In 2006, we established the (INFAT) study, a prospective randomized controlled intervention trial that examined whether decreasing the n-6/n-3 LCPUFA ratio during pregnancy and lactation influences offspring adipose tissue development in children up to 5 years. Our results indicate that maternal supplementation with n-3 LCPUFAs does not reduce offspring obesity risk, which is in line with recent publications.

Associations between long-chain PUFAs in maternal blood, cord blood, and breast milk and offspring body composition up to 5 years: follow-up from the INFAT study.

Background/objectives: Limited research suggests that exposure to long-chain PUFAs (LCPUFAs) during perinatal development can influence adipose tissue expansion later in life. In previous analyses, we observed that maternal LCPUFAs in late gestation promote offspring gestational growth, whereas breast milk n-3 LCPUFAS promote adipogenesis in infants up to 1 year. This follow-up analysis examines these relationships in offspring up to 5 years.

Impact of Dietary Macronutrient Intake during Early and Late Gestation on Offspring Body Composition at Birth, 1, 3, and 5 Years of Age.

Dietary intake during pregnancy as a possible modifiable risk factor for childhood obesity is poorly explored. In a prospective observational study, two multivariable regression models were therefore used to associate maternal diet at 15 and 32 weeks’ gestation with offsprings’ body composition and fat distribution at birth, 1, 3, and 5 years. Mean energy intake was 2157 ± 375 kcal ( = 186) in early and 2208 ± 460 kcal ( = 167) in late gestation.

Leptin in Maternal Plasma and Cord Blood as a Predictor of Offspring Adiposity at 5 Years: A Follow-up Study.

Objective: Perinatal leptin exposure may modulate the risk of adiposity in early childhood. In previous analyses, negative associations between maternal (32 weeks' gestation) and cord blood leptin and offspring body composition at 2 years were observed.

Methods: Associations between maternal/cord blood leptin were assessed with indirect (i.
