title: Lipids and leukocytes in newborn umbilical vein blood, birth weight and maternal body mass index.
abstract: Maternal obesity during pregnancy may influence fetal development and possibly predispose offspring to cardiovascular disease. The aim of the present study was to evaluate the relationship between maternal pre-pregnancy body mass index (BMI) and weight gain during pregnancy, and newborn birth weight, with lipid profile, high-sensitivity C-reactive protein (hs-CRP) and leukocyte in newborns. We performed a cross-sectional study of 245 mothers and their children. Blood was collected from the umbilical vein and assayed for lipid profile, hs-CRP and leukocyte count. Newborns average weight was 3241 g, total cholesterol 53.9 mg/dl, high-density lipoprotein cholesterol (HDL-c) 21.9 mg/dl, low-density lipoprotein cholesterol (LDL-c) 26.2 mg/dl, triglyceride 29.5 mg/dl and leukocytes 13,777/mm3. There was a direct correlation of pre-pregnancy BMI of overweight mothers with total cholesterol (r=0.220, P=0.037) and LDL-c (r=0.268, P=0.011) of newborns. Total cholesterol, LDL-c and HDL-c were higher in pre-term newborns (66.3±19.7, 35.9±14.6 and 25.2±7.7 mg/dl, respectively) that in full-term (52.4±13.1, 25.0±8.7 and 21.5±6.0 mg/dl), with P=0.001, 0.001 and 0.003, respectively. Leukocyte counts were higher in full-term newborns (14,268±3982/mm3) compared with pre-term (9792±2836/mm3, P<0.0001). There was a direct correlation between birth weight and leukocyte counts of newborns (r=0.282, P<0.0001). These results suggest the possible interaction of maternal weight and fetal growth with lipid metabolism and leukocyte count in the newborn, which may be linked to programming of the immune system.
