Curiosity About Cigarettes, Cigars Falling among Students

Fewer middle and high school students in the United States have ever used or are curious about using cigarettes or cigars, according to new research published in the journal Preventing Chronic Disease.

However, the study - conducted by researchers from the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) - identified no change in the percentage of American students who have ever used or are curious about smokeless tobacco.

Spike In Teen Obesity Explained By Decreased Calorie Burn In Puberty

The rise in obesity rates during adolescence may be due to a substantial fall of calories burned during the rapid growth phase of puberty, finds a new study by the University of Exeter Medical School in the United Kingdom.

According to the Centers for Disease Control and Prevention, around 20 percent of adolescents age 12-19 years are obese in the United States. Obese teenagers are more likely to have prediabetes, a condition in which blood glucose levels indicate a high risk for the development of diabetes.

Adolescents who are obese are also at a greater risk for bone and joint problems, sleep apnea, social and psychological problems, and they are more likely to have risk factors for cardiovascular diseases, such as high cholesterol or high blood pressure.

Cesarean Delivery May Increase Risk of Childhood Obesity

Children born by cesarean delivery may have an increased risk of becoming obese, compared with their siblings born by vaginal delivery, says study. This finding may have significant implications for the almost 1.3 million cesarean births per year in the United States.

Cesarean delivery is the most common U.S. surgical procedure and accounts for one third of deliveries nationwide.

The most common risk to children born via cesarean delivery is respiratory problems, while increasing evidence suggests children may also have an increased risk of other adverse health outcomes as adults.

Antibiotics In Early Life Could Raise Children's Food Allergy Risk

Infection in the first year of life can be deadly for an infant, and antibiotic treatment is often the first port of call. But such treatment may have a downside; new research from the University of South Carolina finds early antibiotic exposure could raise a child's risk of food allergies.

While the study did not investigate the reasons behind this association, the researchers say it is likely down to changes in gut microbiota as a result of antibiotic treatment.

Lead author Dr. Bryan Love, of the Department of Clinical Pharmacy and Outcomes Sciences at the South Carolina College of Pharmacy, and colleagues report their results in the journal Allergy, Asthma & Clinical Immunology.

Previous research has suggested that changes to the composition of gut bacteria in early life can have negative implications for health, and antibiotics are known to do just that.

Breast-Feeding May Reduce Asthma Symptoms For At-Risk Infants

A new study provides further evidence of the health benefits of breast-feeding, after finding infants with a genetic susceptibility for asthma development are less likely to experience symptoms of the condition if they are breast-fed.

Asthma is estimated to affect around 8.6 percent of children and adolescents in the United States, making it one of the most common chronic childhood diseases.

Asthma symptoms are the same for children as for adults; these include wheezing, coughing, breathing problems, and chest tightness. However, because children have smaller airways, symptoms may be more severe.

As a result, asthma is the third leading cause of hospital stays and a leading cause of missed school days for children in the U.S.

While the precise causes of asthma remain unclear, studies have suggested the respiratory condition may arise as a result of environmental and genetic factors.

Heatwaves, Cold Snaps May Raise Preterm Birth Risk

Being pregnant during a heatwave is far from the most pleasant scenario for a woman, but new research finds such extreme temperatures may do more than make expectant mothers uncomfortable; they could increase the risk of preterm birth.

In a study published in the journal Environmental Health Perspectives, researchers from the National Institutes of Health (NIH) found that exposure to extreme cold or intense heat during pregnancy increased women's preterm birth risk by up to a fifth.

According to the Centers for Disease Control and Prevention (CDC), in 2014, around 1 in 10 infants in the United States were born preterm - defined as the birth of a baby before 37 weeks of pregnancy.

Preterm birth is the leading cause of infant death in the U.S., and it is also a primary cause of long-term disabilities and neurological disorders, such as cerebral palsy and developmental delay.

Folic Acid May Protect Against Congenital Heart Defects

Foods fortified with folic acid decrease rates of some types of congenital heart defects in Canada, finds new research published in the American Heart Association's journal Circulation.

Folic acid is a B vitamin that our bodies use to make new cells, and it is important for the development of a healthy fetus.

Adding folic acid to white flour, pasta, and cornmeal has been mandatory in Canada since 1998. Evidence of folic acid reducing neural tube defects, oral cleft, and cardiovascular anomalies led to the Government of Canada taking steps to help women of childbearing age increase the amount of folate they consume.

The United States Centers for Disease Control and Prevention (CDC) recommend that women take 400 micrograms of folic acid per day from at least 1 month before getting pregnant to prevent major birth defects of the baby's brain (anencephaly) and spine (spina bifida).

Test That Differentiates Between Bacterial, Viral Infections in Development

An international team of scientists - led by researchers at Imperial College London - has discovered two genes that are switched on when a child has a bacterial infection. This revelation could allow the team to develop a rapid test for doctors' surgeries and hospitals to identify infections such as meningitis, and assist with the growing threat of antibiotic resistance.

The study, published in JAMA, found that the two genes, called IFI44L and FAM89A, only shifted to an "on" state when a bacterial infection was present. This knowledge could enable doctors to distinguish between bacterial and viral infections, and identify early cases of severe infections that could be deadly.

While viral infections are more common than bacterial infections, bacterial infections are often more serious.

Meningitis, septicemia, and pneumonia all occur as a result of a bacterial infection. Differentiating between these potentially life-threatening conditions and viruses can allow health providers to provide quicker, more accurate treatments.

High-Fat Diet in Pregnancy Reduces Beneficial Gut Microbiota for Offspring

Eating a high-fat diet during pregnancy could alter the population of gut microbiota in offspring, which may have negative implications for nutrition and development. This is the conclusion of a new study published in the journal Genome Medicine.

It is well established that what women eat and drink during pregnancy can influence the health and development of their child.

For example, it is recommended that expectant mothers consume 0.4 milligrams of folic acid every day in order to help prevent certain birth defects, and current advice says a healthy, balanced diet is best for both mother and baby.

Sleep Apnea Triggers Pediatric Fatty Liver Disease Progression

Obstructive sleep apnea and low nighttime oxygen - which results in oxidative stress - may trigger progression of pediatric non-alcoholic fatty liver disease to non-alcoholic steatohepatitis.

Non-alcoholic fatty liver disease (NAFLD) describes the accumulation of fat in the liver of people who drink little or no alcohol. In some individuals with the condition, the accumulated fat causes inflammation and scarring in the liver, resulting in a more serious form of the disease called non-alcoholic steatohepatitis (NASH).

A disease of epidemic proportions, rates of NAFLD are increasing worldwide in both adults and children. NAFLD affects an estimated 30 percent of the population in Western countries and up to 9.6 percent of all children.

Around 38 percent of obese children are affected across the NAFLD spectrum, which includes isolated hepatic steatosis, non-alcoholic steatohepatitis, and cirrhosis.

Side Effects of Alzheimer's Gene Visible in Child Brain Development

Certain genes increase the risk of developing Alzheimer's disease. The side effects of the most common of these genes, apolipoprotein E, may be evident as early as in childhood, a study finds.

Genetic risks are just one of the factors that may increase or decrease a person's chances of developing Alzheimer's disease (AD), along with age and family history.

While the symptoms of the rarer early-onset AD - representing less than 5 percent of people with the disease - can appear from the age of 30, the symptoms of the more common type, late-onset AD, is apparent over the age of 65.

This study, published in the online issue of Neurology, finds that the effects of the AD gene apolipoprotein E (APOE) may possibly be seen before the age of 20.

Are Vitamin Supplements for Pregnant Women a Waste of Money?

It is essential that an expectant mother receives adequate nutrition to promote the healthy development of her unborn child. To this end, the market is awash with maternal vitamin supplements. A new review asks whether these pills are as necessary as they claim to be.

Maternal deficiency of certain nutrients has been linked to a number of negative health consequences for mother and child.

Risks include restricted fetal growth, low birth weight, skeletal deformities, and pre-eclampsia.

These well-known dangers support a huge vitamin, mineral, and micronutrient industry aimed at pregnant women.

Typically, these tablets will contain 20 or more vitamins and minerals, often including a range of B vitamins, C, D, E, K, iodine, folic acid, magnesium, zinc, selenium, and copper.

Subclinical Hypothyroidism in Childhood — Current Knowledge and Open Issues

Subclinical hypothyroidism is defined as serum levels of TSH above the upper limit of the reference range, in the presence of normal concentrations of total T4 or free T4. This biochemical profile might be an indication of mild hypothyroidism, with a potential increased risk of metabolic abnormalities and cardiovascular disease recorded among adults. Whether subclinical hypothyroidism results in adverse health outcomes among children is a matter of debate and so management of this condition remains challenging. Mild forms of untreated subclinical hypothyroidism do not seem to be associated with impairments in growth, bone health or neurocognitive outcome. However, ongoing scientific investigations have highlighted the presence of subtle proatherogenic abnormalities among children with modest elevations in their TSH levels. Although current findings are insufficient to recommend levothyroxine treatment for all children with mild asymptomatic forms of subclinical hypothyroidism, they highlight the potential need for assessment of cardiovascular risk among children with this condition. Increased understanding of the early metabolic risk factors associated with subclinical hypothyroidism in childhood will help to improve the management of affected individuals.

Key points

• Subclinical hypothyroidism among children is often a benign and remitting condition, for which risk of progression to overt hypothyroidism depends on the underlying cause (for example, autoimmune disease)
• The optimum management of children with subclinical hypothyroidism depends on the aetiology and degree of TSH elevation and should be individually tailored
• The benefits of levothyroxine therapy are clear for the severe forms of subclinical hypothyroidism; however, uncertainty about this approach still exists for the mild forms of the condition
• In the absence of therapeutic intervention, clinical evaluation and thyroid function tests should be regularly performed to ensure early identification of children who might benefit from treatment
• Growth and neurocognitive outcomes do not seem to be affected in mild subclinical hypothyroidism; however, subtle proatherogenic abnormalities have been detected among children with modest elevations of TSH concentration
• Cardiovascular risk assessment among children and adolescents with subclinical hypothyroidism could help to prevent cardiovascular disease in adulthood

Measles: Causes, Symptoms and Treatments

Measles, also known as Rubeola or morbilli, is a highly infectious illness caused by a virus - a viral infection caused by the rubeola virus.

Measles is an endemic disease; meaning it is continually present in a community and many people develop resistance. If measles enters an area where the people have never been exposed the result can be devastating.

A measles outbreak in 1592 in the island of Cuba killed approximately two-thirds of the native population who had previously survived smallpox. A couple of years later half the indigenous population of Honduras died.

Still too high in fat and sodium in kids' meals.

What will it take to get children to choose fruit instead of ice cream when eating out? Despite a move by many restaurants toward healthier kids' meals, research published in the Journal of Nutrition Education and Behavior shows that while calorie ratings have improved, there is still a way to go in reducing fat, sodium and sugar.

For many American children, eating out is routine.

Studies show that, while home-prepared food has more nutritional value than restaurant meals, the diets of most children in the US already lack fruits, vegetables and low-fat dairy items.

The options available in restaurants, meanwhile, often contain excess calories, solid fats, sodium and added sugar.

Many restaurants have already begun offering healthier choices for children, in anticipation of legislation that will require calorie counts to be included on menus from December 2016.

For the past 6 years, healthier children's dishes have been among the top 10 food trends in the National Restaurant Association's annual survey of chefs.
