Maternal smoking linked to reduced childhood type 1 diabetes risk, effects fade in adulthood

The Lancet Regional Health-Europe study finds that maternal smoking during pregnancy may lower the risk of type 1 diabetes in children, but this protective effect diminishes in adulthood, with adult smoking showing no significant impact on type 1 diabetes risk.

Prenatal cannabis exposure increases risk of adverse birth outcomes, study finds

Infants prenatally exposed to cannabis are more likely to be born preterm, have a low birth weight, and require neonatal intensive care unit (NICU) care than infants without prenatal cannabis exposure, according to a study published today in the scientific journal Addiction.

Using TNF inhibitors during pregnancy not associated with worse fetal or obstetric outcomes

According to new research at ACR Convergence 2023, the American College of Rheumatology's (ACR) annual meeting, continuing tumor necrosis factor inhibitors during pregnancy is not associated with worse fetal or obstetric outcomes and may reduce the risk of severe maternal infections during pregnancy (Abstract #0477).

Study challenges link between low birth weight and childhood neurodevelopmental issues

A recent study in JAMA Psychiatry used Mendelian Randomization to examine the link between low birth weight and neurodevelopmental issues in children. The research found no causal relationship between maternal genetic factors affecting birth weight and offspring neurodevelopment, although some evidence suggested that fetal genetic variants may play a limited role.

How vitamin D and genetics shape early brain development

The study examined how vitamin D levels and vitamin D binding protein genotypes in both pregnant mothers and their children aged 3-5, impact early childhood neurodevelopment. Findings suggest that higher vitamin D concentrations in children were associated with better neurodevelopmental scores, with additional influences from sociodemographic factors and certain genetic variations.

Early metformin therapy falls short in curbing gestational diabetes woes

In a significant randomized clinical trial, early metformin therapy was tested for its potential to lessen insulin dependence and enhance glycemic control in gestational diabetes-afflicted pregnant women; however, it yielded no improvements in diabetes symptoms. While metformin reduced maternal weight gain, its effects on primary diabetes symptoms and other secondary outcomes like infant weight gain were mixed, indicating a need for further focused research to unravel these associations.

Could breastfeeding and delaying soda be the keys to lower childhood obesity rates?

New research presented at the EASD Annual Meeting suggests that breastfeeding for at least six months and delaying the introduction of soda until after 18 months can lead to lower body fat percentages in children at age nine. The study highlights the long-term impact of infant feeding choices on childhood obesity risk.
