Crowdsourcing Apps as Effective at Experts in Providing Healthy Food Information
Crowdsourcing healthy food information and feedback via smartphone apps can be as effective as working with trained experts, according to a new study in the Journal of the American Medical Informatics Association. Researchers used 450 photos of food/drink uploaded onto the Eatery app by 333 unique users in Europe and the United States, comparing the “healthiness” ratings from the app’s users to those from three public health students training in dietary assessment. The results were similar and both were in line with national dietary guidance. "Crowdsourcing has potential as a way to improve adherence to dietary self-monitoring over a longer period of time," wrote the researchers. "The results of this study found that when basic feedback on diet quality by peer raters is crowdsourced, it is comparable to feedback from expert raters, and that peers can rate both healthy and unhealthy foods in the expected direction.” Read more on nutrition.
HUD: $106M to Improve Home Visiting Programs for Pregnant Women, Parents of Young Children
The U.S. Department of Health and Human Services (HHS) has awarded nearly $106 million to expand voluntary, evidence-based home visiting services for pregnant women and the parents of young children. Forty-six states, the District of Columbia and five jurisdictions will share the funding from the Maternal, Infant, and Early Childhood Home Visiting Program; home visits have been shown to prevent child abuse and neglect, while promoting childhood health and development. “These awards allow states to reach more parents and families in an effort to improve children’s health while at the same time building essential supports within their communities,” said Mary Wakefield, PhD, RN, administrator of the Health Resources and Services Administration, in a release.

Study: Hepatitis C Could Be ‘Rare’ In the U.S. By 2036
A new computer model indicates that improved medicine and screening regimens could make hepatitis C a “rare” disease in the United States within the next two decades, according to a new study in the Annals of Internal Medicine. Currently approximately one in every 100 people in the United States are infected with the virus, which is a liver infection that can cause fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain and other symptoms, according to the U.S. Centers for Disease Control and Prevention. The researchers determined that this incidence rate could drop to approximately one in every 1,500 people by 2036 based on current and continuing improvements in treatment, and recommend a greater emphasis on identifying at-risk and infected patients.

Study: Families With Preschoolers Purchasing Fewer High-Calorie Drinks
Recent progress in stalling and perhaps even reversing the childhood obesity epidemic may be linked to fewer families with preschool-aged children purchasing high-calorie drinks, according to a new study in the American Journal of Preventive Medicine. Researchers used Nielsen Homescan data from approximately 43,000 U.S. households with young children from 2000 to 2011, identifying the top 20 foods and beverages purchased. “Decreases in purchases of fluid milks, soft drinks, juice and juice drinks, and grain-based desserts were the primary drivers of this change,” said lead author Christopher Ford, MPH, doctoral candidate in nutrition at the University of North Carolina’s Gillings School of Global Public Health. “These data suggest that these households may have purchased fewer calories from solid fats and added sugars.” Previous research shows that approximately 70 to 80 percent of a preschooler’s diet comes from food purchased at stores.

Peace Corps Withdraws from Three West African Countries Due to Ebola Crisis
The Peace Corps announced yesterday that it was removing all 340 of its volunteers from Liberia, Sierra Leone and Guinea in reaction to the increasing spread of the Ebola virus in West Africa. The organization said it has been working closely with experts from the U.S. Centers for Disease Control and Prevention and the U.S. Department of State to monitor the health crisis and determine how it should respond. “The Peace Corps has enjoyed long partnerships with the government and people of Liberia, Sierra Leone and Guinea and is committed to continuing volunteers’ work there,” according to a Peace Corps release. “A determination on when volunteers can return will be made at a later date.” Read more on global health.
Study: Women Who Live Near Green Spaces Give Birth to Healthier Babies
Pregnant women who live near green spaces—such as parks, community gardens and even cemeteries—give birth to healthier babies with significantly higher birth weights, according to a new study in the journal Occupational and Environmental Medicine. Researchers analyzed data on approximately 40,000 single live births in Tel Aviv, Israel. "We found that overall, an increase of surrounding greenery near the home was associated with a significant increase of birth weight and decreased risk for low birth weight," said Michael Friger, PhD, of Ben-Gurion University of the Negev's Department of Public Health. "This was the first study outside of the United States and Europe demonstrating associations between greenery and birth weight, as well as the first to report the association with low birth weight."

Late last month, the Bipartisan Policy Center, a think tank based in Washington, D.C., released a new white paper, Teaching Nutrition and Physical Activity in Medical School: Training Doctors for Prevention-Oriented Care, that strongly recommends providing greater training in nutrition and physical activity for medical students and physicians in order to help reduce U.S. obesity rates. The report was jointly published with the American College of Sports Medicine and the Alliance for a Healthier Generation, a nonprofit founded by the American Heart Association and the Clinton Foundation as a response to the growing rate of childhood obesity. The report found that current training for medical professionals and students in nutrition and exercise is inadequate to cope with the nation’s obesity epidemic.
A survey conducted for the new report found that more than 75 percent of physicians felt they had received inadequate training to be able to counsel their patients on changing diet and increasing activity levels. It also found that while some schools have stepped up their performance, fewer than 30 percent of medical schools meet the minimum number of hours of education in nutrition and exercise science recommended by the National Academy of Sciences.
“The health care marketplace needs to place greater value on preventive care,” said Jim Whitehead, Chief Executive Officer and Executive Vice President of the American College of Sports Medicine. “Doing so will provide medical schools with the incentive to train their students accordingly. And it will give medical professionals the leverage they need to address healthy lifestyles with their patients.”
NewPublicHealth recently spoke with Lisel Loy, director of the Nutrition and Physical Activity Initiative at the Bipartisan Policy Center, about the report and about how to improve training for medical professionals on nutrition and exercise.
NPH: What was the idea that propelled you to look into making changing to medical school education?
Loy: Well, the technical launching pad was our June 2012 policy report called Lots to Lose: How America’s Health and Obesity Crisis Threatens our Economic Future. And in that, my four co-chairs recommended a suite of policy changes that would improve health outcomes and lower costs for families, communities, schools and work sites. Within that community context they called out the need to improve training for health professionals—not just physicians but health professionals much more broadly defined than that—in pursuit of the goal of reducing obesity and chronic disease and cutting costs.
So that’s sort of the technical answer to your question. The more philosophical answer is as we as a country shift toward more preventive care, they really saw a gap in the education and training of health professionals in terms of being able to best support improved health outcomes. So that’s how they determined that that belonged in our report as a policy recommendation, and since we put out that report we prioritized a handful of recommendations, one of which had to do with health professional training.
Proposed Tobacco Merger Could Boost Smoking Rates
The proposed merger of the Reynolds American and Lorillard tobacco companies announced earlier this week could result in increased smoking rates, according to the Campaign for Tobacco-Free Kids. “This proposed merger is clearly driven by steep smoking declines in the U.S.,” said Matthew L. Myers, president of Tobacco-Free Kids. Myers said cigarette sales fell by 37.1 percent from 2000 to 2013, with the largest decline in 2009, when a 62 cent per-pack increase in the federal cigarette tax was implemented. “Reynolds and Lorillard no doubt hope the economic and political power of a merged company will help them slow or reverse these trends. Elected officials and regulators must be equally aggressive in working to accelerate progress in reducing smoking and other tobacco use.” Read more on tobacco.
Health Education Program Also Reduces Youth Dating Violence
A health education program designed to delay sexual behavior and promote healthy data relationships also significantly reduces dating violence behaviors among minority youth, according to a new study in the American Journal of Public Health. Researchers at the University of Texas Health Science Center at Houston (UTHealth) analyzed 766 students in 10 middle schools in a large, urban school district in southeast Texas, where 44 percent were African American and 42 percent were Hispanic. They looked at four areas—physical victimization, emotional victimization, physical perpetration and emotional perpetration—finding that the It’s Your Game...Keep it Real program reduced all but physical dating violence, which comprised the smallest portion of the program; a revised program with a heavier emphasis on this area is currently being tested in schools. The U.S. Centers for Disease Control and Prevention estimates that 10 percent of high school youth are victims of physical dating violence (with ethnic-minority students at increased risk), with other studies indicating that as many as 20 percent are victims of emotional dating violence.

CDC Report Finds High Rates of Youth Fruit, Vegetable Consumption
Approximately 77.1 percent of U.S. youth ages 2-19 years consume fruit on any given day and 92 percent consume vegetables, according to a recent NCHS Data Brief from the U.S. Centers for Disease Control and Prevention. However, the rate drops as youth age, while at the same time the amount of fruits and vegetables they eat should be increasing. The report used data from the National Health and Nutrition Examination Survey, 2009–2010. The focused report looked only at whether the foods were consumed, and now how much was consumed.

CDC: 60 Percent of Diners Will Use Menu Calorie Counts When Available
Approximately 6 in 10 U.S. adults will choose their restaurant meals in part because of menu label information when it’s available, according to the U.S. Centers for Disease Control and Prevention’s (CDC) latest Morbidity and Mortality Report. Researchers analyzed the self-reported usage of 118,013 adults in 17 states in 2012 to determine that about 57 percent will look to the provided calorie information. New York had the highest rate, with 61.3 percent, while Montana had the lowest, at 48.7 percent. Federal law requires calorie information be provided by any restaurant with 20 or more locations; while the regulations are not yet final, many establishments already voluntarily provide menu labeling, according to the CDC.

Depression, Stress, Hostility Tied to Higher Stroke Risk
Depression, stress and hostility may be linked to a higher risk for stroke, according to a new study in the journal Stroke. Using information provided by approximately 7,000 adults who did not have heart disease or a history of stroke at the beginning of the study, researchers followed up nearly nine years later and determined that depression was associated with an 86 percent increased chance of a stroke or a transient ischemic attack, stress was associated with a 59 percent increase and hostility doubled the risk. “[C]hronic stress and negative emotions are important psychological factors that affect one's health, and findings from this study link these factors to brain health in particular," said the study's lead author, Susan Everson-Rose, an associate professor of medicine at the University of Minnesota, according to HealthDay. "Patients and their health care providers should be aware that experiences of chronic stress and negative emotional states can increase risk for stroke.” Read more on heart health.
Washington State Sees Most Measles Cases Since 1996
A slight decline in Washington State’s mumps and rubella vaccination rate has coincided with the state’s highest number of measles case in 18 years, according to officials. Washington has reported 27 cases so far this year and is currently in the midst of its third outbreak. While homegrown measles was declared officially eliminated from the United States in 2000, infections from people who have travelled overseas remain a threat. There were 554 total cases of measles and 17 outbreaks reported in the United States between Jan. 1 and July 3 of this year. Read more on infectious diseases.
Report: Food Sodium Levels at Many Top Chains Continue to Be Unhealthily High
From 2009 to 2013, the nation’s top restaurant chains reduced the sodium in their foods by an average of only 1.5 percent annually, according to a new report from the nonprofit Center for Science in the Public Interest (CSPI). In a review of 136 meals from 17 chains, researchers determined that approximately 79 percent of the 81 adult meals contained more than 1,500 milligrams (mg) of sodium—or one mg more than the U.S. Centers for Disease Control and Prevention recommends as a full day’s limit. The study also found efforts to reduce sodium to be inconsistent, with some chains actually increasing the amounts over the studied time period. CSPI Executive Director Michael F. Jacobson said the findings indicate that the U.S. Food and Drug Administration’s “wait-and-see” approach to sodium in packaged and restaurant food doesn’t work and that a new approach is needed.

CDC: Antibiotic-resistant Foodborne Germs Remain a Serious Public Health Issue
New data from the U.S. Centers for Disease Control and Prevention (CDC) indicates both positive and negative trends in the ongoing public health fight against antibiotic-resistant foodborne germs, which contribute to an estimated 430,000 U.S. illnesses every year. According to the data, multi-drug resistant Salmonella—which causes approximately 100,000 U.S. illnesses annually—decreased over the past decade, but Salmonella typhi resistance to certain drugs increased by 68 percent in 2012, meaning one of the common treatments for typhoid fever may not be effective. “Our latest data show some progress in reducing resistance among some germs that make people sick but unfortunately we’re also seeing greater resistance in some pathogens, like certain types of Salmonella,” said Robert Tauxe, MD, MPH, deputy director of CDC’s Division of Foodborne, Waterborne, and Environmental Diseases. “Infections with antibiotic-resistant germs are often more severe. These data will help doctors prescribe treatments that work and to help CDC and our public health partners identify and stop outbreaks caused by resistant germs faster and protect people’s health.” Read more on food safety.
Four Communities to Share $120M in HUD Grants for Community Revitalization
Four U.S. communities will split nearly $120 million in U.S. Department of Housing and Urban Development (HUD) grants earmarked for the redevelopment of severely distressed public or HUD-assisted housing and their surrounding neighborhoods. "HUD's Choice Neighborhoods Initiative supports local visions for how to transform high-poverty, distressed communities into neighborhoods of opportunity," said HUD Secretary Shaun Donovan. "By working together, with local and state partners we will show why neighborhoods should always be defined by their potential—not their problems. Together, we will work to ensure that no child's future is determined by their zip code and expand opportunity for all."
The four communities are:
- Columbus (Ohio) Metropolitan Housing Authority — Columbus, Ohio
- Housing Authority of the City of Norwalk/Norwalk (Conn.) Redevelopment Agency
- City of Philadelphia, Office of Housing & Community Development/Philadelphia Housing Authority
- Housing Authority of the City of Pittsburgh/City of Pittsburgh

‘I Got Tested’ Campaign Promotes Importance of Knowing Your HIV Status
A new public information campaign from Greater Than AIDS is using real-life stories to advocate the importance of knowing your HIV/AIDS status. The “I Got Tested” campaign will place materials in clinics to support providers in HIV outreach; provide free HIV testing in select Walgreens pharmacies; and promote hotlines and online resources provided by departments of health and agencies, as well as the U.S. Centers for Disease Control and Prevention. “Despite overwhelming evidence that early diagnosis and treatment play an important role both in the health of those who are positive and in reducing the spread of HIV, many Americans at highest risk for infection still have not been tested,” said Tina Hoff, Senior Vice President and Director of Health Communication and Media Partnerships at the Kaiser Family Foundation, a co-founding partner of Greater Than AIDS, in a release. “This campaign is about helping to reduce the stigma surrounding HIV testing, to encourage patients to ask their providers to get tested, and to connect people with services in their communities.” Read more on HIV/AIDS.
Court: NYC’s ‘Soda Ban’ is Illegal
New York City’s ban on large sugary drinks—often referred to as former Mayor Michael Bloomberg’s “soda ban”—is illegal, according to a 4-2 ruling from the state Court of Appeals. The court found that the local health board that passed the regulation overstepped its authority. "By choosing among competing policy goals, without any legislative delegation or guidance, the Board engaged in law-making and thus infringed upon the legislative jurisdiction of the City Council of New York," wrote Judge Eugene Pigott for the majority. The soda ban was one of several public health initiatives pushed by Bloomberg, along with a ban on cigarettes in certain public spaces and a ban on trans fats from restaurants.

Study: 3 Hours of Television Per Day Can Double Risk of Early Death
Watching more than three hours of television per day may double a person’s risk of an early death, compared to someone who watches less than one hour per day, according to a surprising new study in the Journal of the American Heart Association. Researchers tracked more than 13,000 seemingly healthy adults in Spain, finding that for every two additional hours a person spent watching television, their risk of death from heart disease climbed 44 percent, their cancer death risk climbed 21 percent and their risk of premature death climbed 55 percent for all other causes. The study found no such link for other sedentary causes, including working at a computer and driving. Read more on physical activity.
HHS’ Million Hearts Initiative Launches Health Eating Resource Center
The Million Hearts initiative from the U.S. Department of Health and Human Services has launched a new online resource center to promote healthier eating by individuals and families. The Healthy Eating and Lifestyle Resource Center features lower-sodium, heart-healthy recipes and family-friendly meal plans, and emphasizes managing sodium intake. The searchable recipes include nutritional facts and use everyday ingredients. “This resource helps people see that it’s not about giving up the food you love, but choosing lower sodium options that taste great," said Tom Frieden, MD, Director of the U.S. Centers for Disease Control and Prevention. “Small changes can make a big difference. We can prevent 11 million cases of high blood pressure each year if everyone reduced their daily sodium intake to 2,300 mg.” The Million Hearts initiative was launched with the goal of preventing 1 million heart attacks and strokes by 2017.

3-D Mammograms Improve Breast Cancer Detection Rate, Reduce Recall Rate
Tomosynthesis—also known as 3-D mammography—can increase the detection rate of breast cancer while also decreasing false positives that can lead to multiple and unnecessary re-tests, according to a new study in the Journal of the American Medical Association. Researchers analyzed the results of 454,850 examinations, finding that when 3-D mammography was combined with traditional digital mammograms the detection rate for breast cancer climbed 40 percent while there was a 15 percent decrease in the recall rate, or the percentage of women who needed additional screening due to inconclusive results. The findings come as more and more hospitals and physicians are turning to 3-D mammography. The researchers cautioned that more study was needed into the relatively new technology.

AAP: Reading to Young Kids Starting in Infancy Improves Literacy Later in Life
Read to your kids—aloud and every day—starting as early as their infancy. That’s the latest recommendation from the American Academy of Pediatrics' (AAP) Council on Early Childhood. The policy statement is set to appear in the August print issue of the journal Pediatrics. "This is the first time the AAP has called out literacy promotion as being an essential component of primary care pediatric practice," said statement author Pamela High, MD, director of developmental and behavioral pediatrics at Hasbro Children's Hospital in Providence, R.I., and a professor at Brown University. "Fewer than half of children are being read to every day by their families, and that number hasn't really changed since 2003. It's a public health message to parents of all income groups, that this early shared reading is both fun and rewarding." According to the AAP, reading proficiency in the third grade is the most important predictor of eventual high school graduation, but approximately two-thirds of all U.S. children and 80 percent of kids living in poverty finish third grade lacking in reading proficiency. Reading aloud to a young child can promote literacy while also strengthening family ties. Read more on pediatrics.
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.
