| Abstract | |
Obesity as well as gestation is related to disturbances of glucose metabolism, lipids, hormones and production of inflammatory molecules. Therefore, it is assumed that obesity during pregnancy can influence the development of the fetus, interfering with its body composition and predisposing to cardiovascular diseases in adulthood. This study evaluated the relationship between body composition and maternal serum leptin and adiponectin and the body composition of neonates. The body composition of 215 mothers and their respective neonates was determined by segmented bioimpedance and air displacement plethysmography, respectively. Serum levels of maternal leptin and adiponectin were assessed by Enzyme Linked Immuno Sorbent Assay ELISA. We used univariate regression analysis and multiple linear regression analysis to determine the association between maternal factors and body composition of the newborn, considering as variables the fat mass and the fat free mass of the newborn. The mothers had a mean age of 25.9 (5.2) years, 43.4 per cent were brown and 55.3 per cent belonged to economic class B. Approximately 50 per cent of the mothers presented Body Mass Index (BMI) adequate pre-gestational age, 27.7 per cent were overweight and 10.8 per cent were obese.47,1 per cent of births were normal and 29.1 per cent were cesarean. More female children (55.4 per cent) were born than male children and the mean birth weight was approximately 3373 (423) g. Maternal pre-gestational BMI, maternal fat-free mass, maternal skeletal muscle mass, and adiponectin plasma concentration were positively associated with neonatal fat mass. The maternal fat free mass, maternal skeletal muscle mass and right arm muscle mass were positively associated with the fat free mass of the newborn. Maternal body composition and adiponectin, a protein secreted by adipose tissue, influence the body composition of the neonate. It is expected that further studies will be conducted to investigate the mechanisms involved in the findings of this research (AU) | |
