Expectant mother’s urine can predict baby’s birth weight using BCAA

Madrid,Nov4:When it comes to the baby’s birth weight, it can now be predicted, courtesy the mommy to be’s urine, says a new study. The study by Biomed Central says that urine of a mommy-to-be can help identifying lifestyle interventions that help maintain a healthy birth weight for their baby. Abnormal fetal growth and birth weight are well-established risk factors for

Abnormal fetal growth and birth weight are well-established risk factors for chronic diseases later in life, including the development of type-2 diabetes and obesity. Mireille Toledano, co-lead author of the research said, ‘We used a technique called NMR spectroscopy to identify, for the first time, a panel of 10 urinary metabolites in the 3rd trimester of pregnancy that was associated with greater fetal growth and increased birth weight. These metabolites included steroid hormones and important biological building blocks called branched-chain amino acids (BCAAs).’ BCAAs are essential nutrients that are vital during pregnancy as an energy source for the growing fetus. In this study, changes in BCAAs and other metabolites detected in the urine were able to explain 12 percent of the variation seen in birth weight, independent of other known predictors such as parent’s own weight and maternal smoking or alcohol intake.

Muireann Coen, co-lead author added, ‘We found that a 50 percent increase in the mother’s level of individual BCAAs equated to a 1-2.4 percent increase in birth weight, or 5-11 grams. When we made comparisons with the lifestyle and environmental exposures of the women in our study we found that the variability between BCAA profiles of individual mothers could be partially explained by levels of physical activity, vitamin D, coffee consumption and smoking exposure, suggesting them to be potential areas of intervention to promote a healthy birth weight.’ The research team from Spain at ISGlobal, collected urine samples and lifestyle questionnaire data from over 800 pregnant women, aged 28-33 years old, from two locations in Spain (Gipuzkoa and Sabadell), making it the most comprehensive study of urinary metabolites and fetal weight outcomes to date. The two locations in Spain differed in socio-demographic factors, with women in Gipuzkoa reported to be more educated, from a higher social class and generally healthier than women from Sabadell. This distinction allowed for useful comparisons to be made between women from different backgrounds and different geographical location.
