Pregnant women not getting enough omega-3, critical for infant development

APrON study suggests pregnant & lactating women not meeting recommended intake

2015-03-25
(Press-News.org) This news release is available in French.

Alberta Pregnancy Outcomes and Nutrition (APrON) is a birth cohort involving over two thousand women and their infants from Calgary and Edmonton that was funded by Alberta Innovates Health Solutions and includes researchers at the University of Alberta and the University of Calgary. The main objective of APrON is to understand the relationship between maternal nutrient status during pregnancy and maternal mental health and child health and development. As part of the project, the APrON team studied the first 600 women in the cohort during and after their pregnancy to see whether they were consuming enough omega-3 long chain polyunsaturated fatty acids (omega 3-LCPUFA) to meet current recommendations. The team has just published their results in the journal Applied Physiology, Nutrition, and Metabolism.

Omega-3 LCPUFA include eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and docosahexaenoic acid (DHA). A source of these is required during pregnancy for fetal and placental development and is critical for the development of the infant, particularly for brain development.

The American Dietetic Association along with Dietitians of Canada recommends that all healthy adults including pregnant and lactating women consume at least 500 mg/day of omega-3 LCPUFA. The European Commission and the International Society for the Study of Fatty Acids and Lipids (ISSFAL) specifically recommends that pregnant and lactating women consume a minimum of 200 mg DHA per day.

The women from this group of APrON participant lived in Edmonton and Calgary. The team found that the majority of participants, despite a high level of education and income, were not meeting these recommendations for omega-3 LCPUFA during pregnancy and lactation.

According to the study: "Only 27% of women during pregnancy and 25% at three months postpartum met the current European Union (EU) consensus recommendation for DHA. Seafood, fish and seaweed products contributed to 79% of overall n-3 long chain polyunsaturated fatty acids intake from foods, with the majority from salmon. Results suggest that the majority of women in the cohort were not meeting the EU recommendation for DHA during pregnancy and lactation."

The current study found women who took a supplement containing DHA were 10.6 and 11.1 times more likely to meet the current EU consensus recommendation for pregnancy and postpartum, respectively. Recommendations could also be met by following the Health Canada recommendation to consume one to two portions per week of fish high in omega-3 fatty acids.

The results of this also study suggests that nutritional counseling and education about benefits of a supplement source of LCPUFA should extend beyond pregnancy as 44% percent of the women in the cohort who reported taking a supplement during pregnancy were no longer taking these supplements when breast feeding at three months postpartum.

The current study provides useful information for health practitioners and for future interventions (dietary or supplement recommendations) aimed at helping women obtain LCPUFA in their diet to ensure they are able to meet the needs of their infants.

INFORMATION:

The study "Women who take n-3 long chain polyunsaturated fatty acid supplements during pregnancy and lactation meet the recommended intake" by Xiaoming Jia, Mohammadreza Pakseresht, Nour Wattar, Jamie Wildgrube, Stephanie Sontag, Murphy Andrews, Fatheema Begum Subhan, Linda McCargar, Catherine J Field* and the APrON study team was published today in the journal Applied Physiology, Nutrition, and Metabolism.

Risk factors associated with overweight cluster already in children

2015-03-25
Lifestyle-related cardiometabolic risk factors cluster already in children in the same way as in adults, according to research from the University of Eastern Finland. A cardiometabolic risk score was used to evaluate cardiometabolic risk in different age groups. The results show that risk factor levels even lower than those generally accepted as risk factor thresholds for type 2 diabetes and atherosclerotic vascular disease are harmful when several risk factors cluster. In addition, a common mutation on the PNPLA3 gene associated with fatty liver in adults was found to ...

MDC researchers greatly increase precision of new genome editing tool

2015-03-25
CRISPR-Cas9 is a powerful new tool for editing the genome. For researchers around the world, the CRISPR-Cas9 technique is an exciting innovation because it is faster and cheaper than previous methods. Now, using a molecular trick, Dr. Van Trung Chu and Professor Klaus Rajewsky of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and Dr. Ralf Kühn, MDC and Berlin Institute of Health (BIH), have found a solution to considerably increase the efficiency of precise genetic modifications by up to eightfold (Nature Biotechnology: doi:10.1038/nbt.3198)**. "What ...

Business people prefer working in their cars instead of trains, planes and airports

2015-03-25
Noisy and cramped conditions in trains, planes and airports are discouraging many commuters and business people from working while travelling, new research shows. Sociologist Dr Donald Hislop and psychologist Dr Carolyn Axtell found that the most popular place to work was in vehicles in the car park of a motorway service station. In a paper in the journal Work, Employment and Society, Dr Hislop, of Loughborough University, and Dr Axtell, of the University of Sheffield, say "significant variations" in noise and lack of space "inhibited people's ability to work" on ...

Research reveals high prevalence of sleep disordered breathing in adults with sickle cell

2015-03-25
A new study in the Journal of Clinical Sleep Medicine revealed that 44 percent of adults with sickle cell disease who report trouble sleeping actually have a clinical diagnosis of sleep disordered breathing, including sleep apnea, which lowers their oxygen levels at night. "Previous research identified pain and sleep disturbance as two common symptoms of adult sickle cell disorder," said Sunil Sharma, M.D., Associate Professor of Pulmonary and Critical Care Medicine, Sidney Kimmel Medical College at Thomas Jefferson University and first author on the study. "We wanted ...

A difficult climate: New study examines the media's response to the IPCC

2015-03-25
The UN Intergovernmental Panel on Climate Change (IPCC) periodically releases Assessment Reports in order to inform policymakers and the public about the latest scientific evidence on climate change. The publication of each report is a key event in the debate about climate change, but their reception and coverage in the media has varied widely. A study, published today in the journal Nature Climate Change, has for the first time analysed how Twitter, TV and newspapers reported the IPCC's climate evidence. Understanding how media coverage varies is important because people's ...
