A Brazilian study of 43 family units found that fathers who consumed more ultra-processed foods before conception tended to have babies with higher birth weight and thicker skin-folds, suggesting paternal diet may influence fetal development via epigenetic mechanisms, though the study only shows correlation and more research is needed.
A Brazilian study of 43 triads found that fathers who consume more ultra-processed foods before conception are associated with higher birth weight and greater fat in specific areas of the newborn’s body, while maternal diet showed the opposite effect. The researchers propose epigenetic mechanisms, including methylation of the IGF-II gene, as a possible link. While intriguing, the small sample size means larger studies are needed, and findings highlight the importance of including men in preconception health guidance.
A new analysis of more than 11 million U.S. births found no association between water fluoridation and birth weight or preterm birth, addressing earlier smaller studies that suggested a link. The study did not assess IQ effects, and researchers note that any potential risks appear small at typical public-health fluoride levels, while dental benefits remain a key consideration.
A study from Brazil reveals that a father's health, particularly his weight, significantly influences a baby's birth weight, with higher paternal BMI linked to lower birth weights. This research highlights the importance of considering paternal health and lifestyle, including diet and exercise, in prenatal care. The study emphasizes the role of epigenetics, where a father's lifestyle can affect sperm quality and gene expression, impacting fetal development. These findings suggest that both parents' health should be considered in strategies to ensure healthy birth outcomes.
New research from Norway suggests that parents who were big babies themselves are more likely to have children with high birth weights. The study analyzed data from over 600,000 sets of babies and parents born in Norway between 1967 and 2002. The findings revealed that children of parents with macrosomia (high birth weight) had a substantially increased risk of high birth weight themselves. The risk was higher when both parents had high birth weights, but even having just one parent with a high birth weight increased the risk. Maternal obesity was also linked to higher birth weights, even in mothers who did not have macrosomia in infancy. Further research is needed to determine the extent to which genetics or habits play a role in this intergenerational pattern.
A new study has found that marijuana use during the first trimester of pregnancy can have a significant impact on fetal development, including a decrease in birth weight and smaller head circumference. Even if marijuana use is stopped by the third trimester, the baby may still be born with a smaller head circumference. The study recommends that pregnant women avoid using marijuana altogether, as there is no known safe level of use during pregnancy. The study also found that combining smoking cigarettes and marijuana during pregnancy has an even bigger impact on birth weight than either substance alone.

The use of marijuana during pregnancy is on the rise, and the impact can be even worse when combined with smoking cigarettes.
