Overly Clean Homes Can Increase Child’s Risk of Asthma, Allergies
Living in an overly clean home can actually increase an infant’s risk of developing allergies or asthma as they grow older, as their bodies are not given the chance to develop appropriate responses, according to a new study in the Journal of Allergy and Clinical Immunology. The researchers behind the study were surprised by the results, as they had been looking deeper into data that found that exposure to roach, mouse and pet droppings and other allergens increased asthma risk. "What we found was somewhat surprising and somewhat contradictory to our original predictions," said study co-author Robert Wood, MD, chief of the Division of Allergy and Immunology at the Johns Hopkins Children's Center in Baltimore, according to HealthDay. "It turned out to be completely opposite—the more of those three allergens you were exposed to, the less likely you were to go on to have wheezing or allergy." Approximately 40 percent of the allergy- and wheeze-free children in the study were raised in homes with high amounts of allergens and bacteria, while only 8 percent who suffered from both conditions had been exposed to allergens and bacteria while infants.

Study: Prenatal Medicaid Policy Reduces Smoking, But Doesn’t Improve Preterm Birthweights
While a Medicaid policy that fast-tracks applications of pregnant women helps reduce smoking during pregnancy, it has no significant effect on improving preterm birth rates or low birth weights, according to a new study in the journal Health Affairs. The study specifically looked at Medicaid’s presumptive eligibility and unborn-child option, which provides coverage for prenatal care. “Although the prevalence of prenatal smoking in the United States has declined in recent decades, it is nearly twice as high among low-income women enrolled in Medicaid than it is in the U.S. population as a whole,” said Marian Jarlenski, PhD, lead author of the paper. “Our research shows that Medicaid’s presumptive eligibility policy led to a nearly 8 percentage-point decrease in smoking during pregnancy, but neither policy significantly improved rates of preterm birth or babies born small for their gestational age.” Read more on maternal and infant health.
CDC: Watercress Tops ‘Powerhouse’ Fruits and Vegetables List
With a “nutrient density score” or 100.00, watercress tops the U.S. Centers for Disease Control and Prevention’s (CDC) new list of “powerhouse” fruits and vegetables. The list of 41 foods was created as a tool for nutrition education and dietary guidance. The study defined “powerhouse” as foods most strongly associated with reduced chronic disease risk, which are often green leafy, yellow/orange, citrus and cruciferous items. Chinese cabbage, chard, beet green and spinach rounded out the top five. The full list is available here. Read more on nutrition.
EPA Plans to Cut Carbon Emissions 30 Percent by 2030
The U.S. Environmental Protection Agency (EPA) announced plans today to reduce carbon emissions by 30 percent by 2030. The new Clean Power Plant proposal would be the first to cut emissions from existing power plants, which produce approximately one-third of the country’s domestic greenhouse gas emissions. The EPA estimates the proposed changes will help the United States avoid up to 6,600 premature deaths, up to 150,000 asthma attacks in children and up to 490,000 missed work or school days. "Climate change, fueled by carbon pollution, supercharges risks to our health, our economy, and our way of life,” said EPA Administrator Gina McCarthy, adding “By leveraging cleaner energy sources and cutting energy waste, this plan will clean the air we breathe while helping slow climate change so we can leave a safe and healthy future for our kids.” Read more on air and water quality.
Study: Tax on Total Calories in Sugary Drinks the Most Effective Way to Reduce Consumption
Tying a sugary drink tax to the amount of calories in a drink rather than its serving size would be more effective at reducing their consumption, according to a new study in the American Journal of Agricultural Economics. The study, which was financed by the Robert Wood Johnson Foundation, determined that such a tax of four-hundredths of a penny for every calorie would reduce calorie consumption by 9.3 percent; a tax of half a cent for each ounce in a can or bottle would reduce consumption by only 8.6 percent. “It provides a better incentive to the consumer to switch to lower-calorie drinks, which would be taxed at a lower rate than higher-calorie drinks,” said Chen Zhen, MD, a research economist at the food and nutrition policy research program at Research Triangle Institute and the lead author of the study, according to The New York Times. “One of the concerns about taxing ounces of sugar-sweetened beverages is that consumers are paying the same tax whether they buy 12 ounces of a drink with 150 calories or 12 ounces of a drink with 50 calories.” Read more on nutrition.
CDC: $19.5M for Innovative Public Health Prevention Research
Late last week the U.S. Centers for Disease Control and Prevention (CDC) awarded $19.5 million to 26 academic institutions for innovative public health prevention research to reduce health disparities. The grants will help the communities develop new methods to avoid or counter risks for chronic health care issues such as heart disease, obesity and cancer. “Prevention Research Centers have reached up to 31 million people in 103 partner communities, some of which are the most underserved in the country,” said Ursula E. Bauer, PhD, MPH., director of CDC’s National Center for Chronic Disease Prevention and Health Promotion, in a release. “By involving communities in conducting and disseminating research, this network of centers ensures that effective and innovative health strategies can be readily shared and applied where most needed.” Read more on prevention.
Mental Health Patients with Primary Care Physicians are Better at Managing their Health
Mental health patients who receive primary care from a physician’s office are generally more engaged in the active management of their mental health than are people who rely on outpatient clinics or emergency departments, according to a new study in the journal Health Education & Behavior. Using data from a large nationally representative survey, researchers assessed patient activation among patients diagnosed with depression in relation to variables such as the site of their usual source of care, community characteristics and other demographic characteristics. “Patients with mental disorders are less engaged in their health care than patients with other chronic diseases, so it is important to activate this group,” said Jie Chen, PhD, assistant professor in the department of health services administration at the University of Maryland School of Public Health. “In communities where patient activation is low, such as low-income communities with a large population of foreign-born individuals, there is an even greater need for interventions at mental health care institutions to engage residents in their health.” Read more on mental health.
Study: Low Cost of Food a Contributor to U.S. Obesity Epidemic
One of the driving factors in America’s growing obesity epidemic may very well be the increased access to cheap food, according to a new study. The average American spends only about one-tenth of their disposable income on food, compared to the 1930s, when the rate was about one-quarter. In addition, the average per capita consumption of calories has climbed approximately 20 percent since 1970. “Not only has food been getting cheaper, but it is easier to acquire and easier to prepare,” said Roland Sturm, lead author of the report and a senior economist at RAND, a nonprofit research organization. “It's not just that we may be eating more high-calorie food, but we are eating more of all types of food.” Possible public health solutions for this trend include imposing taxes on foods with low-nutritional value, as well as subsidies or discounts for healthier foods, according to the researchers.

Expensive Co-pays a Barrier for Some Kids to Proper Asthma Treatments
Parents with higher health insurance co-pays report using less expensive asthma drugs, giving their children less medication than prescribed and even putting off doctor visits or trips to the emergency department for the respiratory disorder, according to a new study in the journal JAMA Pediatrics. Approximately 1 in 10 U.S. children suffer from asthma, and the prevalence of the illness is greater in low-income populations. "It is concerning that the children we deal with are sometimes more vulnerable in areas we didn't recognize," said Jefry Biehler, MD, chairman of pediatrics at Miami Children's Hospital in Florida. "We have to be careful that we don't create a void for those families that can't afford all the things they need for their child, but who are above the financial level that gives them government insurance that will provide everything at no or minimal cost.” Read more on pediatrics.
Study: Kids’ Cereals Average 40 Percent More Added Sugar than Adult Cereals
One bowl of kids’ cereal every morning would total as much as 10 pounds of sugar in a year, according to a new study from the Environmental Working Group (EWG). The organization assessed the sugar content of 1,500 cereals. While almost all had added sugar, the levels were higher in the 181 cereals specifically marketed to children—an average of 40 percent higher. “When you exclude obviously sugar-heavy foods like candy, cookies, ice cream, soft and fruit drinks, breakfast cereals are the single greatest source of added sugars in the diets of children under the age of eight,” said nutritionist and EWG consultant Dawn Undurraga, co-author of the organization’s new report, Children’s Cereals: Sugar by the Pound, in a release. “Cereals that pack in as much sugar as junk food should not be considered part of a healthy breakfast or diet. Kids already eat two to three times the amount of sugar experts recommend.” Read more on nutrition.
HHS, EU Making Progress in Fight Against Antimicrobial Resistance
This week the U.S. Department of Health and Human Services (HHS) and the European Commission released a progress report of the Transatlantic Taskforce on Antimicrobial Resistance (TATFAR), a joint effort to combat antimicrobial resistance. In 2009, TATFAR identified and adopted 17 recommendations; the progress report includes one new recommendation to go along with 15 existing recommendations.
Notable TATFAR activities from 2011-2013 include:
- Adoption of procedures for timely international communication of critical events that might indicate new resistance trends with global public health implications
- Publication of a report on the 2011 workshop, “Challenges and solutions in the development of new diagnostic tests to combat antimicrobial resistance” to the TATFAR website
- Joint presentations to the scientific community to increase awareness about the available funding opportunities on both sides of the Atlantic
There are an estimated 25,000 deaths in Europe and 23,000 deaths in the United States linked to drug-resistant infections each year. Such infection also cost the United States and the European Union billions of dollars annually in avoidable health care costs and productivity losses. Read more on global health.
Women with Unintended Pregnancies Take the Shortest Maternity Leaves
Women with unintended pregnancies also take the shortest maternity leaves, according to a recent study from the University of Maryland School of Public Health published in the journal Women’s Health Issues. “We know that it’s better for women to take time off after childbirth to take care of their physical and mental health,” said Rada K. Dagher, MD, assistant professor of health services administration. “Returning to work soon after childbirth may not be good for these women or for their children.” Dagher’s previous research has indicated that six months of maternity leave is optimal for reducing a woman’s risk of postpartum depression. In addition to policies that enable women to take longer maternity leaves, she said there is also a need to counsel both women and men who are at risk for unintended pregnancies about effective contraceptive methods.

CDC: Parasitic Diseases a Significant U.S. Public Health Issue
Although the perception is that parasitic diseases only occur in poor and developing countries, people in the United States are also at risk for the diseases, which can cause serious illnesses, including seizures, blindness, pregnancy complications, heart failure and even death, according to the U.S. Centers for Disease Control and Prevention (CDC). The CDC has designated five neglected parasitic infections (NPIs) as U.S. public health priorities: Chagas disease, cysticercosis, toxocariasis, toxoplasmosis and trichomoniasis. While they can be treated when identified, there remains difficulty in correctly diagnosing the diseases, according to the CDC.
The estimates of the burden of NPIs include:
- More than 300,000 people living in the United States are infected with Trypanosoma cruzi, the parasite that causes Chagas disease, and more than 300 infected babies are born every year.
- There are at least 1,000 hospitalizations for symptomatic cysticercosis per year in the United States.
- At least 14 percent of the U.S. population has been exposed to Toxocara, the parasite that causes toxocariasis, and each year at least 70 people—most of them children—are blinded by resulting eye disease.
- More than 60 million people in the United States are chronically infected with Toxoplasma gondii, the parasite that causes toxoplasmosis; new infections in pregnant women can lead to birth defects and infections in those with compromised immune systems can be fatal.
- Trichomoniasis can cause pregnancy problems and increase the risk of other sexually transmitted infections including HIV. The Trichomonas parasite is extremely common, affecting 3.7 million people in the United States, although it is easily treatable.

Study: Many People Who Believe They Are Sensitive to Gluten Do Not Get Tested for Celiac Disease
Despite the increasing number of gluten-free products on grocery store shelves, many people who believe they are sensitive to gluten do not undergo tests to rule out celiac disease, according to a new study in the journal Nutrition in Clinical Practice. The autoimmune disorder damages the lining of the intestines, resulting in digestive symptoms and potential complications, and left untreated can lead to significant health problems. “There is a great deal of hype and misinformation surrounding gluten and wheat allergies and sensitivities. The group of so-called ‘non-celiac gluten sensitivity’ remains undefined and largely ambiguous because of the minimal scientific evidence,” said study author Jessica R. Biesiekierski, according to Reuters. “This non-celiac gluten sensitivity entity has become a quandary, as patients are powerfully influenced by alternative practitioners, Internet websites and mass media who all proclaim the benefits of avoiding gluten- and wheat-containing foods.” Read more on nutrition.
Study: ECGs Should Be Added to Health Screenings for High School Athletes
Electrocardiograms should be added to the health screening programs for high school athletes, according to a new study presented at the Heart Rhythm Society's annual meeting in San Francisco. The test would increase the odds of detecting medical conditions that could lead to sudden cardiac arrest and death. Researcher used data on approximately 5,000 athletes, ages 13-19, who underwent standard American Heart Association screening and also received an electrocardiogram, finding that while 23 were found to have significant heart abnormalities that required further evaluation, seven would not have been detected without an electrocardiogram.

Study: Banning Chocolate Milk in Elementary Schools Also Decreases Overall Sales, Increases Waste
Banning chocolate milk in 11 Oregon elementary schools and replacing it with healthier fat-free white milk had the unintended consequence of reducing milk consumption overall, according to a recent study in the journal PLOS One. The study determined that the chocolate milk ban led to a 10 percent overall drop in milk sales; a 29 percent increase in the amount of wasted milk; drops in calcium and protein intake; and a 7 percent decrease in the number of students taking part in the Eugene School District's lunch program. "Given that the role of the federal school meal program is to provide nutritious meals to students who may otherwise have no access to healthy foods, I wouldn't recommend banning flavored milk unless you have a comprehensive plan in place to compensate for the lost nutrients when kids stop drinking milk altogether,” said Nicole Zammit, former assistant director of nutrition services at the Eugene School District in Oregon, in a Cornell University news release. The study was conducted by the Cornell Food and Brand Lab. Read more on nutrition.
CDC: Significant Drops in Five Major Diabetes-related Complications
The last two decades has seen declines in five major diabetes-related complications, according to a new study in the New England Journal of Medicine. Researchers at the U.S. Centers for Disease Control and Prevention (CDC) found declining rates of lower-limb amputation (about 50 percent), end-stage kidney failure (about 30 percent, heart attack (more than 60 percent) , stroke (about 50 percent) and deaths due to high blood sugar (more than 60 percent). “These findings show that we have come a long way in preventing complications and improving quality of life for people with diabetes,” said Edward Gregg, Ph.D., a senior epidemiologist in CDC’s Division of Diabetes Translation and lead author of the study. “While the declines in complications are good news, they are still high and will stay with us unless we can make substantial progress in preventing type 2 diabetes.” A recent study determined that approximately one in 10 U.S. adults have either type 1 or type 2 diabetes.

FDA Sees Rising Number of Cases of Injuries Linked to E-cigarettes
The rising use of e-cigarettes has been accompanied by a rising number of injury complaints linked to e-cigarettes, including burns, nicotine toxicity, respiratory problems and cardiovascular problems, according to new data. From March 2013 to March 2014 there were more than 50 such complaints filed with the U.S. Food and Drug Administration (FDA), roughly the total reported over the previous five years. The findings come as the FDA prepares to regulate e-cigarettes and other "vaping" devices for the first time. Read more on injury prevention.
A new article from The Atlantic Cities reports on a recent study that finds that restaurants are shifting to become the predominant teen hang-out spot, rather than the malls of the past. According to a recent report on teen behavior, teenagers now spend more money on food and events than on clothes. And while an increase in mall closings may be driving younger people to eateries, the report finds that a greater interest in hanging out at restaurants also drove some of the drop in mall traffic—along with competition from the Internet.
The report doesn’t say what the teens are eating while they mingle, but the trend comes at a good time for them to access information on healthier diets, as under the Affordable Care Act many restaurants must now post nutrition information. Though studies have been mixed about the results of menu labeling, the U.S. Centers for Disease Control and Prevention notes that, overall, public health studies may be beginning to show that menu labeling may influence consumers to choose healthier options. And while many food outlets have chosen to share that information online rather than on walls, digital-savvy teens may already have the tools to find it—though they may need a push from social media or other educational outreach channels to do so.

Eat well. That’s today’s theme for National Public Health Week—and it’s good advice. After all, according to the American Public Health Association, Americans are now eating 31 percent more calories than we did 40 years ago, including 56 percent more fats and oils and 14 percent more sugars and sweeteners. The average American eats 15 more pounds of sugar a year today than in 1970.
There are new food-oriented websites and smartphone apps (many free) that can help people keep track of what foods they’re eating and what’s in those foods.
At the Milk Street Café in Boston, for example, the restaurant’s ordering site lets you filter the full menu into just the categories you want. Click low “fat” and the tailored breakfast menu leaves off the breakfast pastries and zooms in on the yogurt parfaits.
Other recent apps include:
- Locavore, which points to farmers’ markets and produce stands in your neighborhood.
- Harvest, which offers tips for choosing ripe produce.
- Fooducate, a food database on your smartphone that includes basic nutrient and calorie information, plus high points of each food such as the fiber quantify of crackers.
- Substitutions, an app finds alternatives when you can’t use the ingredient in the original recipe because of an allergy or other dietary restriction. Popular tip: Swap in fat-free yogurt when the recipe calls for fat-free sour cream to save calories.
- The U.S. Department of Agriculture hosts the Food Access Research Atlas, which presents a spatial overview of food access indicators for low-income and other census tracts using different measures of supermarket accessibility. The app is valuable for community planning and research.
Study: Fertility Drugs Not Tied to Increased Risk of Breast Cancer
Fertility drugs are not linked to an increased risk of breast cancer, according to a new long-term study in the journal Cancer Epidemiology, Biomarkers & Prevention. Researchers analyzed records for 9,892 U.S. women who were followed for 30 years after having been evaluated for infertility between 1965 and 1988, finding that about 38 percent of them were exposed to the fertility drug clomiphene and about 10 percent were exposed to drugs known as gonadotropins. There were 749 breast cancers diagnosed during the three decades, but women who were exposed to either drug were just as likely as the women who hadn’t been exposed to fertility drugs to develop breast cancer. The study did note an increased risk of breast cancer for the small group of women exposed to the highest doses of clomiphene. "It's reassuring that if women desire pregnancy and unfortunately have infertility that they can undergo treatment without modification of their overall risk for cancer later," said Kurt Barnhart, MD, president of the Society for Reproductive Endocrinology and Infertility, to Reuters Health. He was not involved in the study. Read more on cancer.
Study: CDC’s Salt Recommendations Are Too Low
The U.S. Centers for Disease Control and Prevention’s (CDC) salt guidelines are too low, according to a new study in the American Journal of Hypertension. Researchers reviewed 25 previous studies, concluding that both too much and too little salt can be harmful. They concluded that the safest intake range was between 2,645 and 4,945 mg of salt a day, although the CDC recommends less than 2,300 mg of salt per day for healthy people under age 50, and less than 1,500 mg per day for most people over age 50. "For most people, there is no reason to change their dietary habits concerning salt, as most people eat what appears to be the safest amount," said review author Niels Graudal, MD, a senior consultant at Copenhagen University Hospital in Denmark, according to HealthDay.

HUD to Provide Disaster Assistance to Washington State Mudslide Victims
Having officially been given a major disaster declaration yesterday, Snohomish County and the Sauk-Suiattle, Stillaguamish and Tulalip Indian Reservations in Washington state will now received federal disaster assistance from the U.S. Department of Housing and Urban Development (HUD) to help recover from the flooding and mudslides that began on March 22. Among the assistance:
- Offering the State of Washington and other entitlement communities the ability to re-allocate existing federal resources toward disaster relief
- Granting immediate foreclosure relief
- Making mortgage insurance available
- Making insurance available for both mortgages and home rehabilitation
- Offering Section 108 loan guarantee assistance
- Information on housing providers and HUD programs
"Families who may have been forced from their homes need to know that help is available to begin the rebuilding process,” said HUD Secretary Shaun Donovan in a release. "Whether it's foreclosure relief for FHA-insured families or helping these counties to recover, HUD stands ready to help in any way we can." Read more on disasters.
NHTSA: Rear Cameras for All New Cars by May 2018
All new vehicles under 10,000 pounds will be required to have rear visibility technology—or rear cameras—by May 2018, according to a new rule issued by the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA). According to NHTSA, the technology significantly reduces injuries and fatalities due to backover incidents; there are an average of 210 deaths and 15,000 injuries each year caused by such incidents, with children under age 5 accounting for 31 percent and adults ages 70 and older accounting for 26 percent. "Safety is our highest priority, and we are committed to protecting the most vulnerable victims of backover accidents — our children and seniors," said U.S. Transportation Secretary Anthony Foxx. "As a father, I can only imagine how heart wrenching these types of accidents can be for families, but we hope that today's rule will serve as a significant step toward reducing these tragic accidents."

Study: Diet of Fruit, Vegetables Linked to Reduced Risk of Death
Diets heavy on fruits and vegetables can reduce the risk of death at any age by as much as 42 percent, according to a new study in the Journal of Epidemiology and Community Health. Using data on the eating habits of more than 65,000 people in England from 2011 to 2013, researchers determined that the risk of death was reduced by 36 percent with five to seven portions, 29 percent with three to five portions and 14 percent with one to three portions. More specifically, they also determined that eating seven or more portions of fruits and vegetables reduced the risk of death from heart disease by 31 percent and the risk of death from cancer by 25 percent. "We all know that eating fruit and vegetables is healthy, but the size of the effect is staggering," study author Oyinlola Oyebode, at the department of epidemiology and public health of University College London, in a release. "Vegetables have a larger effect than fruit, but fruit still makes a real difference. If you're happy to snack on carrots or other vegetables, then that is a great choice but if you fancy something sweeter, a banana or any fruit will also do you good.” Read more on nutrition.
Affordable Care Act Expected to Hit Goal of Coverage for 7 Million
Despite a glitch-filled rollout of HealthCare.gov that allowed few people to enroll over the first month, the Affordable Care Act and its online portals appear to be on track to meet the original goal of enrolling 7 million people by its deadline of yesterday, March 31, according to Obama administration officials. More than 6 million had signed up for health care coverage as of last week and the run up to the deadline saw a surge that should put the total over 7 million. The administration also recently announced an extension of the enrollment deadline for Americans who had attempted to sign up for coverage but were impeded by technological problems.
