Omega-3 Fatty Acids and Fecundation, Pregnancy and Breastfeeding

Carlos Alberto Politano¹,

Jorge López-Berroa²

Abstract: Long-chain omega-3 (n-3) polyunsaturated fatty acids (PUFAs), such as the eicosapentaenoic and docosahexaenoic acids, have been linked to human health in all stages of life, from fetal development to aging. These PUFAs act as precursors for various metabolites involved in the prevention of certain diseases. The recognizable effects of these supplements prior to pregnancy (oocyte maturation), during pregnancy (improvement in the risk of premature delivery, among others) and in the offspring (in terms of cogniti… Show more

During pregnancy, maternal polyunsaturated fatty acids (PUFA) are transferred to the fetus through the placenta by specific FA transporters (FATP). A higher perinatal exposure to n-6 over n-3 PUFA could be linked to excess fat mass and obesity development later in life. In this context, we aimed to assess the associations between long chain PUFAs (LC-PUFAs) (n-6, n-3, and n-6/n-3 ratios) measured in the placenta at term birth with obesity-related parameters in the offspring at 6 years of age and assess whether these associations are dependent on the placental relative expression of fatty acid transporters. As results, the PUFAn-6/PUFAn-3 ratio was 4/1, which scaled up to 15/1 when considering only the arachidonic acid/eicosapentaenoic acid ratio (AA/EPA ratio). Positive associations between the AA/EPA ratio and offspring’s obesity risk parameters were found with weight-SDS, BMI-SDS, percent fat mass-SDS, visceral fat, and HOMA-IR (r from 0.204 to 0.375; all p < 0.05). These associations were more noticeable in those subjects with higher expression of fatty acid transporters. Therefore, in conclusion, a higher placental AA/EPA ratio is positively associated with offspring’s visceral adiposity and obesity risk parameters, which become more apparent in subjects with higher expressions of placental FATPs. Our results support the potential role of n-6 and n-3 LC-PUFA in the fetal programming of obesity risk in childhood. For the present study, 113 healthy pregnant women were recruited during the first trimester of pregnancy and their offspring were followed up at 6 years of age. The fatty acid profiles and the expression of fatty acid transporters (FATP1 and FATP4) were analyzed from placental samples at birth. Associations between LC-PUFA (n-6, n-3, and n-6/n-3 ratios) and obesity risk parameters (weight, body mass index (BMI), percent fat mass, visceral fat, and homeostatic model assessment of insulin resistance (HOMA-IR)) in the offspring at 6 years of age were examined.

Background: Pregnancy is a physiological state in which the female body undergoes a series of changes and adaptations to provide the best possible conditions for the growth and development of the forming baby. The internal adaptations that take place lead to the production of inflammation, which is necessary for the initial and final stages of pregnancy (embryo implantation and induction of labor). Gestational diabetes mellitus is considered to be the most common pathology during this period. However, many more serious health complications can arise, which include pre-eclampsia, fetal stunting, and preterm labor. The purpose of this study was to analyze the impact of the levels of individual eicosanoids on the course of normal pregnancy and the possibility of pathologies including gestational diabetes and pre-eclampsia. Methods: Sixty-nine pregnant women who were overweight or obese before and during pregnancy were studied. Eicosanoids were extracted as appropriate and then determined using liquid chromatography. The levels of eicosanoids studied in pregnant women differed not only according to the week of pregnancy but also in relation to individual anthropometric and biochemical parameters. Results: There was a significant correlation between being overweight and having a high BMI before pregnancy—as well as biochemical parameters of lipid and carbohydrate profiles—and the occurrence of pathological conditions in pregnancy. Conclusions: Eicosanoids are involved in the pathology of pregnancy associated with the occurrence of gestational diabetes and pre-eclampsia. Salicylic acid may find use in the treatment of pregnant women exposed to both phenomena, as well as in overweight and obese women found before pregnancy. Diets rich in natural salicylates, methods of administration, and pharmacotherapy and dosage need further study. Some of the mediators (lipoxin, prostaglandin and leucotrien) may be new diagnostic markers in pregnancy pathology and intervention pathways in the future.
