MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Some studies have found that maternal gestational diabetes mellitus (GDM) places offspring at increased risk of long-term adverse outcomes, including obesity. However, most of studies are from high income countries, with limited data from low to middle income countries. The present study, conducted at urban and suburban sites in 12 countries, found that the increased risk for children of GDM mothers compared with non-gestational diabetes mellitus mothers was 53% for obesity, 73% for central obesity, and 42% for high body fat.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Prenatal malnutrition and other stresses may cause small newborn babies, who are more likely develop type 2 diabetes and other chronic diseases during adulthood. However, whether such relation is causal remains to be determined. Genetic associations provide a new approach to provide evidence for such causality.

Response: Our clinical research during the last three years has been focused on the effects of music during the early stages of life; in our preliminary studies, applying music to pregnant patients using abdominal speakers, we discovered that there was no fetal reaction to music and that the fetus would only be able to hear it as a distorted whisper because of the effects of the abdominal wall. We thought that it would be necessary to get the music closer to the fetus, and we decided to try to apply the music vaginally. It was a great decision.

Dr. Borrell: Racial/ethnic disparities in birth outcomes in the United States are well documented, with non-Hispanic Black women exhibiting the worst outcomes. Several hypotheses have been proposed as explanation to this finding such as the weathering hypothesis and cumulative or chronic experiences of social inequality and racism. However, these hypotheses have only accounted for the stress burden associated with the mother’s race/ethnicity, as her race/ethnicity has been the sole information used to determine the child’s race/ethnicity, ignoring the possible stress associated with the father’s race/ethnicity. We used NYC birth- and death-linked data from 2000 to 2010 to examine the added effect of paternal race/ethnicity on adverse birth outcomes (low birth weight [LBW], small for gestational age [SGA], preterm births, and infant mortality [IM]) among NYC women.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Depression and anxiety are common during pregnancy, and up to 5% of all pregnant women are treated with serotonin uptake inhibitors (SRI). It is now known that SRIs do not cause major malformations in humans, however recent animal studies have suggested that fetal early SRI exposure may cause changes in brain microstructure and neuronal signaling. Prior human studies have shown that fetal SRI exposure leads to transient postnatal adaptation syndrome, as well as to an increased risk of developing childhood depression.
We used electroencephalography (EEG) and advanced computational methods to assess both the local and global cortical function of the newborn brain. We found that several aspects of newborn brain activity are affected by exposuse to SRI during pregnancy. Most importantly, the communication between brain hemispheres, and the synchronization between cortical rhythms were weaker in the SRI-exposed newborns. These changes were most likely related to SRI exposure, because they did not correlate with the psychiatric symptoms of the mothers.

MedicalResearch.com: What is the background for this study?
Dr. Komro: Epidemiologists have done a thorough job describing the income-health gradient, which shows a clear association between income and health. That is, as income increases, exposure to health risks and premature mortality decreases. Each step down on the income ladder decreases one’s health for many reasons related to material resources, physical environment exposures and social circumstances.
The income to health association begins at birth, and more than one in four women giving birth in the U.S. are below the poverty level, putting nearly 1 million babies at risk each year. Low-income mothers are more likely to give birth prematurely, to have low birth weight babies, and to suffer the death of their infant during the post-neonatal period (28 to 364 days old).
Given the importance of the income-health gradient, we set out to test the health effects of policies that are designed to increase economic security among low-income families. Our main question is: Do policies designed to reduce poverty and improve family economic security also improve health?
One relevant policy is minimum wage laws. A federal minimum wage was first enacted in 1938. The real value (in 2015 dollars) of the federal minimum wage reached a high of $10.85 in 1968. The current federal rate is $7.25. Many cities and states have passed minimum wage laws that are higher than the federal rate, and currently there is a range of minimum wage increases under active public and policymaker discussion.
Given that some states pass minimum wage standards and others do not, and that laws within states change over time, we took advantage of all the changes that have occurred to design a natural experiment. Our natural experiment examined the effects of state minimum wage laws on infant health.

Dr. Heath: Vaccinating pregnant women is an important and proven strategy for protecting young infants against tetanus, influenza and pertussis. Among the infants at highest risk for complications of these infections are infants born prematurely but it is generally believed that because antibody transfer from mother to baby is maximal in the 3rd trimester, babies born prematurely may miss out on the benefits of maternal vaccination.

Dr. Brown: Smoking during pregnancy is a risk factor for several pregnancy-related outcomes including low birthweight and preterm birth. Evidence for a link with schizophrenia is scant. We analyzed a maternal biomarker of smoking called cotinine, a nicotine metabolite, in mothers of nearly 1,000 schizophrenia cases and 1,000 controls in a national birth cohort in Finland. We found that heavy smoking in pregnancy was related to a 38% increase in schizophrenia risk in offspring and that as cotinine levels increased even in the more moderate smokers risk of schizophrenia also increased.
