Response: The U.S. Institute of Medicine (IOM) in 2007 published estimates of the economic costs associated with preterm birth. That report is publicly available: https://www.ncbi.nlm.nih.gov/pubmed/20669423. The total societal cost over a lifetime of a single year’s cohort of infants born preterm was estimated as $26 billion in 2005 US dollars. The study in Pediatrics sought to provide more current estimates of one component of those costs: medical care between birth and 12 months and to answer two additional questions:

Response: This study proves that asthmatic children already have a hyperactive calcium channel that’s extremely sensitive to environmental triggers.
If these children contract a virus, such as RSV, the hyperactive channel causes more severe symptoms that may require care in a hospital setting.
When a child developed asthma or bronchitis in the past, doctors thought these conditions could only be triggered by environmental allergens. There was no explanation why two out of three children ages five and under who wheeze and cough – and still test negative for allergies.
We needed to explore the mechanisms of the calcium molecule and the epithelial cells, which seem to trigger these symptoms without an allergic reaction. If the molecule’s behavior is producing the cough, we just need to figure out how to control the molecule to properly deactivate the cough mechanism in the asthmatic child

Response: Iron deficiency has been associated with impaired neurodevelopment and iron supplementation is recommended to those at risk. While it is well known that very low birth weight infants are at risk of iron deficiency, less has been known regarding the large subgroup of children born with only marginally low birth weight (2000-2500g). In the present study, we previously showed that this relatively common group of otherwise healthy children is at risk of iron deficiency during infancy (Berglund Pediatrics 2010;126).
In the study published this week, we now also found that supplementation during the first six months of life had long term positive effects on their behavioral profile, with significant reduction of externalizing behavioral problems.

Response: Infants are at greatest risk for severe pertussis (whooping cough) morbidity and mortality, especially during the first months of life before infant immunizations begin. CDC and the Advisory Committee on Immunization Practices (ACIP) currently recommend that women receive a dose of Tdap during the third trimester of each pregnancy. This recommendation has been in place since 2012. By getting Tdap, pregnant women pass critical short-term protection to their unborn babies. This helps protect babies until they are old enough to start getting their own whooping cough vaccines at 2 months of age.
The purpose of our study was to evaluate the effectiveness of maternal Tdap during pregnancy at preventing whooping cough in infants <2 months of age.
In our evaluation, Tdap administration during the third trimester of pregnancy prevented more than 3 in 4 (78%) infant cases. Additionally, Tdap vaccination during pregnancy was even more effective (90%) at preventing whooping cough serious enough that the baby had to get treatment in a hospital.

Response: Childhood obesity is becoming an emerging public health issue worldwide, owing to its association with a variety of health problems at younger ages in adulthood, including obesity, type 2 diabetes and cardiovascular diseases. Identification of prenatal and early life risk factors is key for curbing the epidemic of the childhood obesity.
Main finding of the present study is that among pregnant women, elevated blood pressure is associated with a greater risk of overweight and obesity for their children.

Response: Approximately 8% of all infants are born prematurely (preterm birth <37 weeks postmenstrual age). Preterm infants have many challenges including establishment of adequate pulmonary gas exchange. Due to not yet fully developed lungs, preterm infants require respiratory support consisting of respirators and other forms of non-invasive ventilation modalities and supplemental oxygen. Bronchopulmonary dysplasia (BPD) is the commonest morbidity among very low birth weight infants as 40% of survivors at postmenstrual age <30 weeks develop BPD. This is a serious condition as it can lead to short- and long-term pulmonary complications, increased hospital visits and neurodevelopmental impairment. BPD is defined where preterm infants require respiratory support and/or supplemental oxygen at 36 weeks postmenstrual age.
A number of therapeutic and non-therapeutic modalities have been used to prevent BPD including inhaled nitric oxide (iNO). In 2006, the NO CLD trial demonstrated that iNO prevented BPD (Relative benefit 1.81; CI 1.27-2.59, P = 0.006) if used according to the NO CLD Protocol (Ballard et al., New England Journal of Medicine, 355:343-353, 2006). Our study (NEWNO; Newborns treated with Nitric Oxide) was designed to replicate the NO CLD study.

Response: The increase in children who move between their parent's homes after a divorce is one of the major changes in children's life circumstances during the last decade. Spending equal amounts of time in both parents' homes means that these children move fifty times a year. Child experts have claimed this to be stressful and potentially harmful to children's attachment relations to their mothers. Especially for children this young the practice of joint physical custody has been questioned.

Response: TThe goal of this study was to investigate whether playing youth tackle football, particularly before the age of 12, is associated with worse emotional, behavioral, and cognitive difficulties later in life. Participants in this study included 214 former amateur and professional American football players who were part of the LEGEND study at Boston University. Participants had an average age of 51. 43 played high school football, 103 played college football, and there were 68 professional American football players. The former players were divided into two groups: those who began playing tackle football before age 12 and those who began at age 12 or older. Participants received telephone-administered cognitive tests and completed online measures of depression, behavioral regulation, apathy, and executive functioning, such as initiating activity, problem-solving, planning, and organization. Results from former players who started playing tackle football before the age of 12 were compared to those of participants who started playing at age 12 or later.
The study showed that participation in tackle football before age 12 increased the odds for having problems with behavioral regulation, apathy and executive functioning by two-fold and increased the odds for clinically elevated depression scores by three-fold. These findings were independent of the total number of years the participants played football or at what level they played, such as high school, college, or professional. Even when a specific age cutoff was not used, younger age of exposure to tackle football corresponded with worse clinical status.

Response: Smoking kills millions of people every year. It is well established that increasing tobacco prices is the most effective way to reduce tobacco consumption and hence mitigate the devastating effects of tobacco on health. Taxation on tobacco products is high in the European Union, which makes cigarettes less affordable. However, transnational tobacco companies are known to manipulate prices, ensuring that cheap or ‘budget’ cigarettes are still available. This is particularly important for younger smokers and those of low socioeconomic status who are more sensitive in price increases.
Smoking during pregnancy, as well as exposure of pregnant women and babies to cigarette smoke increase infant mortality. There is also evidence that increasing tobacco prices is associated with lower infant mortality. However, researchers typically use average or premium cigarette prices. We analysed 54 million births from 23 European Union countries to see if the differential between average priced and budget cigarettes (i.e. the availability of cigarettes much cheaper than average priced ones) is associated with infant mortality.
We found that increasing average cigarette prices by 1 Euro per pack was associated with 0.23 fewer deaths per 1,000 live births in the same year and an additional 0.16 fewer deaths per 1,000 live births in the following year. A 10% increase in the price differential between budget and average priced cigarettes was associated with 0.07 more deaths per 1,000 live births the following year. This means that 3,195 infant deaths could potentially have been avoided in these 23 countries if there was no price difference between cigarette products over the 10-year study period.

Response: For many years, researchers have documented links between health-related behaviors and educational outcomes such as letter grades, test scores, and other measures of academic achievement. However, many of those studies are becoming out-of-date or have used samples that were not nationally representative. The aim of this study was to see if previous findings held in a current, national sample of high school students.
Consistent with previous studies, our findings revealed that regardless of sex, race/ethnicity and grade-level, high school students who received mostly A’s, mostly B’s, or mostly C’s had higher levels of most protective health-related behaviors and lower levels of most health-related risk behaviors. For example, we found that:

Response: The incidence of food allergy is increasing worldwide, particularly among children, and yet no handy test is available for general public. There are plenty of allergens testing methods for the factories producing the products, we wanted to solve this issue. Our pilot test showed wide variation in allergen contents in packaged food products and restaurant meals. Hidden allergens (like gluten in salad dressing, likely from additives) were also found.

Response: The relationship between pesticides and adverse birth outcomes has been recognized as an important question for quite some time, and there have been many good studies on the topic. Since randomly exposing people to different levels of pesticides is clearly unethical, researchers focused on the health consequences of non-occupational pesticide exposure often have to choose between detailed studies that follow a couple hundred or couple thousand individuals through pregnancy or larger scale studies that use easier to observe, but less accurate metrics of pesticide exposure (e.g. nearby crops or crop types). Here we tried to provide complementary insight by bridging the gap between detail and scale using detailed pesticide use data and individual birth certificate records for hundreds of thousands of births in an agriculturally dominated region of California. While we found negative effects of pesticide use on birth outcomes including low birth weight, preterm birth and birth abnormalities, these effects were generally in the magnitude of a 5-9% increase in probability of an adverse outcome, and only observed for individuals exposed to very high levels of pesticides.

Response: The background for this study was the widespread uncertainty and general concern among the public about increasing exposure to weak radio frequency electromagnetic fields (EMF-RF). The concern on whether using your cell phone while pregnant can harm your foetus are mainly due to the extensive use of cell phones, that emit EMF-RF. Even though the RF-EMF exposure that may reach the foetus is very low, evidence from previous epidemiological studies with mothers and children are inconsistent as to whether EMF-RF emission from cell phone might harm the developing brain of the foetus. This includes also animal experiments where the exposure may be very different from that in humans.
We therefore studied the association between maternal cell phone use during pregnancy and child’s neurodevelopment at 3 and 5 years. We included around 45,000 mother and their children from all over Norway from the Norwegian Mother and Child Study (MoBa study) and used language development as the outcome because we in previous studies found this parameter to be sensitive to exposure to neurotoxicants. T
here was no evidence of a harmful effect of the mother using her cell phone during pregnancy on her child’s neurodevelopment at 3 and 5 years. Surprisingly, we even found that the more the mother was using her cell phone during pregnancy the better language and motor skills her child had at 3 years of age. We observed no associations when the child was 5 years old.

Response: Two well-documented risk factors for aberrant weight gain and obesity is whether your mother was obese when she was pregnant and the amount of weight she gained.
Up until now few studies have asked questions about whether the pattern of weight gain in pregnancy affect outcomes in offspring, such as birth weight.
In a cohort of over 16,000 pregnant women and infants, we found that regardless of the obesity status (BMI) of the mother at the time of pregnancy, weight gain that occurs up until week 24, had the strongest effect on infant birth weight. Infants born to mothers who had weight gain in excess of the 2009 IOM guidelines from conception until week 24, had a 2.5 times higher likelihood of being born large for gestational age. The weight gain that occurred after 24 weeks until delivery, did not attenuate this risk.

Response: In recent years, findings from research in developmental neuroscience indicate that the myelination of the prefrontal cortex (PFC) extends into the third decade of life, proceeding more slowly than in other brain regions. Because subcortical and sensory brain regions appear to mature earlier, this and other findings have been taken as evidence that adolescents may have less ability to control their behavior than children do. These findings spawned theories of “imbalanced” adolescent brain development that were proposed to explain heightened vulnerability to risky behavior and adverse health outcomes during adolescence.
Although there is little doubt that as adolescents enter adulthood, they are at risk for many health outcomes that can accompany the initiation of such behaviors as driving, having sex, using drugs, and playing sports. But most adolescents make it through this period of development without serious health consequences. Thus, the argument that a brain deficit is responsible for such adverse health outcomes seemed to overgeneralize effects that only occur for a minority of adolescents. Furthermore, when my colleagues and I examined the evidence in support of imbalance theories, we found it unconvincing. Indeed, it seemed that findings from neuroscience were interpreted through the lens of stereotypes about adolescents that conflate exploration with impulsivity. That is, many of the risky behaviors that attract adolescents are novel activities that reflect lack of experience rather than lack of control over behavior.

Response: Insufficient sleep has a negative impact on health, cognition and mood and is linked to motor vehicle accidents. However, sleep loss in adolescents has become an epidemic and arises in part from biological processes that delay sleep and wake timing at the onset of puberty. This biology does not fit well with early school start times (before 8:30 a.m.). Despite recommendations from the American Academy of Pediatrics and the American Academy of Sleep Medicine to delay school start times, most schools in the U.S. have current start times before 8:30 a.m.
In this nationally representative study of US parents of teens, we examined whether parents supported or opposed later school start times (after 8:30 a.m.). We also examined what may have influenced their opinions.
We found that only about half of surveyed parents of teens with early school start times supported later school start times. Opinions appeared to depend in part on what challenges and benefits were expected to result from the change.
For example, parents who expected an improvement in their teen’s academic performance or sleep quantity tended to support the change, whereas parents that expected negative impact on afterschool activities or transportation opposed delays in school start times. We also found that parents had misconception about sleep needs of their adolescents, as the majority perceived 7-7.5 hours of sleep as sufficient, or possibly sufficient even at this young age when 8-10 hours are typically recommended.

Response: Wearing contact lenses can increase your chances of getting a severe eye infection. Eye infections can lead to serious problems, including blindness. All contact lens wearers can help prevent serious eye infections by correctly wearing and caring for their contact lenses.
Eighty-one percent of young adults, 85% of adolescents, and 88% of older adults regularly did at least one risky behavior related to their contact lenses. The most frequently reported risk behaviors in adolescents were not visiting an eye doctor as least annually, sleeping or napping in lenses, and swimming in lenses.
Among young adults and older adults, the most frequently reported risk behaviors were replacing lenses at intervals longer than those prescribed, replacing lens storage cases at intervals longer than those recommended, swimming in lenses, and sleeping or napping in lenses.

Response: Neonatal hypoglycaemia – low blood sugars in newborns – affects up to one in six babies born. It involves a sustained dip in blood sugar levels following birth. Blood glucose is the only fuel for babies’ brains (adults have alternative, back-up sources). So, if left untreated, this condition can cause developmental brain damage and lowered education outcomes later in life.
In developed economies, as many as a third of babies born are at risk. Risk factors include being born smaller or larger than usual, preterm babies and babies whose mothers have any form of diabetes – this last a growing group, with the rising incidence of gestational (pregnancy-related) diabetes.
We wanted to systematically track a cohort of babies to see if hypoglycaemia in babies affects their long-term health and development. So we designed the CHYLD study – Children with Hypoglycaemia and their Later Development. We are following 614 New Zealand babies born at risk of low blood sugar levels (neonatal hypoglycemia) into childhood to see if the condition affects their later growth and development. Our team includes researchers from the Liggins Institute, the University of Auckland, Waikato Hospital, the University of Canterbury and the University of Waterloo.
Half of the babies in the study were diagnosed with, and treated for low blood sugars. Seventy percent received extra, continuous monitoring of their blood sugar levels, which detected in some babies low levels that were not diagnosed by the heel-prick tests.

Response: Maternal preeclampsia causes morbidity to mothers and infants worldwide. Retinopathy of prematurity (ROP) is a leading cause of childhood blindness worldwide. This study was done to gain insight into the effects of preeclampsia on ROP in a clinical population.
The literature is mixed with some reports that preeclampsia increases risk of Retinopathy of prematurity, whereas others suggest preeclampsia is protective or has no effect. The presence of circulating anti-angiogenic factors in preeclamptic mothers that can enter the fetal circulation lends biologic plausibility to the notion that maternal preeclampsia might interfere with developing vascular beds in the fetus, such as the retina, and potentially lead to severe ROP. However, a report using an experimental model provided evidence that uteroplacental insufficiency, a characteristic of preeclampsia, led to protective mechanisms in the offspring that reduced oxygen-induced retinopathy and promoted overall growth.

Response: This study examined the association between pet ownership, specifically dog or cat ownership, and children’s physical and mental health. There has been a lot of previous work looking at this association and these previous results seemed to show that kids with pets have better health than those without pets. The hypothesis has been that pets can improve children’s health by increasing physical activating and improving young people’s empathy skills.
We used data from over 5,000 households in California which was obtained from the California Health Interview Survey and looked at physical and mental health outcomes among children in households with pets vs. without pets.
We found that children in households with pets do have better health than those without pets, but that after we account for factors such as family income and housing type, for example, there is no evidence of an association between pet ownership and health. That is, households that have pets are more likely to be higher income, to be in a house as opposed to an apartment, and to have healthier adults in the household, for example - and these factors are also associated with better child health.

Response: Neonatal drug withdrawal is common; in the U.S. about 1 infant is born every 25 minutes with signs of drug withdrawal. Neonatal drug withdrawal is a well-recognized complication of intrauterine exposure to illicit or prescription opioids, but other psychotropic medications can also cause signs of withdrawal. Psychotropic medications are frequently co-prescribed with opioids in pregnancy, and the use of both has increased significantly, raising concerns about an increase in the incidence and severity of neonatal drug withdrawal due to potential drug-drug interactions, but these risks are not well understood.
In this study, we found a 30-60% increase in the risk of neonatal drug withdrawal associated with co-exposure to antidepressants, benzodiazepines and gabapentin, compared to opioids alone; no significant increase in risk was observed for atypical antipsychotics and Z-drugs. Exposure to psychotropic polypharmacy along with opioids was associated with a two-fold increased risk of withdrawal.
