FDA Takes Another Step to Reduce Consumption of Trans Fats
The U.S. Food and Drug Administration has taken another step to reduce American’s consumption of trans fats with a preliminary determination that partially hydrogenated oils (PHOs) are not “generally recognized as safe” for use in food. PHOs are the primary dietary source of artificial trans fat in processed foods. Up next is a 60-day comment period to collect more information and input on exactly what it would take for food manufacturers to reformulate products so that they do not include PHOs. “While consumption of potentially harmful artificial trans fat has declined over the last two decades in the United States, current intake remains a significant public health concern,” said FDA Commissioner Margaret A. Hamburg, M.D. “The FDA’s action today is an important step toward protecting more Americans from the potential dangers of trans fat. Further reduction in the amount of trans fat in the American diet could prevent an additional 20,000 heart attacks and 7,000 deaths from heart disease each year—a critical step in the protection of Americans’ health.” Read more on food safety.
Lack of Light Disrupts Sleep Cycles During Hospital Stays, Increases Patient Discomfort
Hospital stays may be even more uncomfortable for most patients than necessary because of an overall lack of adequate light, according to a new study in the Journal of Advanced Nursing. The small study found that lower levels of daytime light exposure were connected to worse mood, as well as more fatigue and pain, in patients. The poor light interfered with their bodies’ ability to adopt a normal sleep-wake cycle. Researchers found the lowest levels of daytime light exposure were tied to worse mood and more fatigue and pain among patients, compared to those whose rooms were better-lit during the day. "Until now, no one has looked at the associations among light and outcomes such as sleep, mood and pain experienced in the hospital," said Esther Bernhofer, lead author of the study and a nurse researcher at the Cleveland Clinic's Nursing Institute. "This study forms a basis for testing future lighting interventions to improve sleep-wake patterns, mood and pain in hospitalized adults.” Read more on mental health.
Study: No Link Between IVF, Increased Risk of Cancer in Kids
Despite years of concerns, a new study on in vitro fertilization (IVF) found no link between the conception technique and an increased risk of cancer in children. The findings were published in the New England Journal of Medicine. Researchers analyzed data on more than 106,000 children born through assisted reproduction between 1992 and 2008, finding the risk of them developing cancer was "the same as naturally conceived children," according to lead researcher Alastair Sutcliffe, MD, a specialist in general pediatrics at the University College London. More than 5 million children have been born through IVF since the first successful birth in 1978. "This study is extremely reassuring and should relieve anybody's anxiety about IVF," concluded Lawrence Grunfeld, MD, an associate clinical professor of obstetrics, gynecology and reproductive science at the Mount Sinai Icahn School of Medicine, in New York City.

Harvard Pilgrim Health Care Foundation’s work on childhood obesity is driven by one startling fact: one in three Massachusetts children are overweight or obese. To find out why, Executive Director Karen Voci and her colleagues went to the places where children learn and play—schools, after school programs and child care centers— and found that children were sitting for most of the day and foods were heavy on starch and sugar. With a limited budget, Voci and her team found opportunities and partners in Massachusetts, New Hampshire and Maine to improve childhood obesity rates.
“It’s hard to measure what you’re accomplishing,” said Voci at one session during the American Public Health Association (APHA) 2013 meeting. “These environments look and feel different, but it’s hard to capture this feeling in a meaningful statistic that can be used further down the road.”
As a result, most of the results shared focused on process and intermediate outcomes rather than actual health outcomes—for now—but the communities are optimistic that they’re moving in the right direction.
Voci underscored the importance of staying committed, noting that Harvard Pilgrim and its partners had been at this for years and they were in fact moving the needle. Session presenters shared successes from Massachusetts, New Hampshire and Maine.
Harvard Pilgrim partnered with the Massachusetts Department of Public Health and other foundations and businesses on the Mass in Motion initiative to combat childhood obesity in its home state. Led by their elected officials, 14 communities developed health improvement plans and received technical assistance to improve local food sources and increase physical activity. The multifaceted initiative included a “call to action” report, as well as a Governor’s Executive order establishing a nutrition standard for the food procured for the state of Massachusetts. In addition, the program implemented a body mass index (BMI) regulation that required schools to screen children’s BMI in order to identify potential issues early. The Department of Public Health worked within these communities to share information on physical activity and nutrition, all culminating in growth of the program to 52 communities in the state.
Communities in Eastern Massachusetts are showing concrete signs of progress on the childhood obesity front. Reports from this summer have shown that the obesity rate for the region’s children under six years of age has decreased by 21.4 percent—likely due in part to initiatives such as Mass in Motion, the Cambridge Healthy Children Task force and Shape Up Somerville.
CATCH Kids Club is an evidence-based, after-school environment that has been adopted by 117 sites in nine of New Hampshire’s ten counties. The CATCH program promotes exercise and healthy eating in elementary school children with a four-phased approach:
- Curriculum development
- Staff and booster training
- Staff support
- Environment and policy assessment
In the environment and policy assessment phase, CATCH found that 93 percent of participating after-school programs made four or more changes to improve children’s physical activity and healthy eating. In addition, most sites now offer programs that promote these goals between three and five times a week.
In Maine, the Let’s Go! 5210 Goes to School program offers resources to help schools create a culture of health. It aims to take the focus off of the highly charged weight management issue and shift it toward four simple and embraceable goals for each day:
- Eat 5 fruits and vegetables
- Limit screen time to 2 hours or less
- Get at least 1 hour of exercise
- Drink 0 sugary drinks
While each school decides which of these four goals it would like to adopt, they often end up promoting all four points of the program as time goes on. In fact, the 5210 initiative reaches children in all 16 Maine counties in schools, after school programs, early childhood education, doctors’ offices and more locations.
One of the key lessons learned was to engage busy school representatives at a level that made sense for them. “Don’t ask them to do something unrealistic,” said Torey Rogers of the Let’s Go! 5210 Goes to School Program and The Barbara Bush Children’s Hospital at Maine Medical Center.
Representatives from each of these programs offered insights and lessons learned when it comes to working with schools. When speaking with school representatives, organizations are often successful when they relate the goal back to the mission of schools: education. By highlighting the secondary benefits to attendance and active participation of students, organizations can engage teachers as partners in public health initiatives.

In 2012 alone, the fast food industry spent $4.6 billion to advertise mostly unhealthy products, with many of those ads specifically targeting children and teens. A new report, Fast Food FACTS 2013, examined 18 of the nation’s top fast-food restaurants, following up on a 2010 report to see how the food selection and advertising landscapes have changed. And while there have been some positive developments—healthier sides and beverages are available in most kids’ meals—the findings indicate there is still a very long way to go.
Detailed findings from the report, which was supported by a grant from the Robert Wood Johnson Foundation, will be presented today at the American Public Health Association’s (APHA) annual meeting in Boston.

NewPublicHealth spoke with Jennifer Harris, the Yale Rudd Center for Food Policy & Obesity’s director of marketing initiatives and lead author of the report, and Marlene Schwartz, the Center’s director, about their findings and how fast food advertising continues to impact our nation’s youth.
NewPublicHealth: Has any progress been made in the nutritional quality of fast food kids' meals?
Jennifer Harris: There have been a lot of changes in kids’ meals over the past three years and a lot of it has been good. Most of the restaurants have added healthy sides and healthy beverages to their kids’ meals. Now it’s possible to get a fairly healthy kids’ meal at most of the restaurants we looked at. But the problem is it’s kind of like finding a needle in a haystack. Almost all of the meals they offer are high in fat, sugar or sodium.
Marlene Schwartz: The odds of you getting the healthy combination when you go are extraordinarily low. For every healthy combination, there are roughly 250 unhealthy combinations.
Research shows that people invariably look at Mondays as a time to reconsider their habits and even perhaps to make changes in their lives. The Monday Campaigns movement is a non-profit initiative that works to make healthy behaviors a focus at the beginning of every week.
NewPublicHealth spoke with Rachelle Reeder, Program & Research Associate at The Monday Campaigns, about how their efforts are helping to improve public health.
NewPublicHealth: We’re very interested about the Monday conferences and college students. Are they a specific demographic that you’re targeting now?
Rachelle Reeder: Yes. We’ve been targeting many different groups, whether it’s hospitals, college students, K-12. We target a lot of different groups depending on the campaigns. We provide universities—or any of our partners, but universities particularly—with catchy social marketing campaigns to kind of help and encourage the students to adopt and sustain healthy behaviors, and we do everything for free. So we might be working with student health centers, with food service providers, wellness teams or student groups themselves. But our organization is this blend of marketers and public health professionals, so usually what we’re able to offer universities are these compelling, creative campaigns that are also backed by research and a theory.
So that’s one of the great things about the Monday campaigns. And actually, I’m a public health professional myself and I’ve seen a lot of universities or public health services out there and they’re doing great things, but they don’t always have the skills or the capacity to market themselves, so that’s kind of where we step in and provide them with that marketing and creative expertise.
NPH: How would the efforts toward college students be different than they would be toward an older or even a younger demographic?
Reeder: It just kind of depends on the tone of the different campaigns that we take. For instance, we have Man Up Monday, which was really successful over at Murray State University. That campaign has kind of a cheeky sort of fun vibe that’s supposed to be a little bit funny, but what it is it’s reaching out to young men and it’s all about sexual health. Basically they encourage young men to engage in healthy sexual behavior on Mondays, to use Monday as the day to restock condoms, to make an appointment to get tested or to just reflect on decisions over the weekend. So that’s just an example of one of our university partners and that campaign wouldn’t necessarily be something we’d target for younger audiences or something like that.
HPV Vaccines Less Effective in African-American Women than in White Women
Perhaps because of their lower participation rates in clinical trials, African-American women are less likely to benefit from available human papillomavirus (HPV) vaccines that guard against cervical cancer, according to new findings presented at the 12th annual International Conference on Frontiers in Cancer Prevention Research. The two most popular vaccines in use protect against infection by HPV 16 and HPV 18, which are responsible for about 70 percent of cervical cancers. However, these two subtypes are half as likely to be found in black women as they are in white women. Researchers found that the most common infections for white women are from subtypes 16, 18, 56, 39 and 66; the most common for black women are 33, 35, 58 and 68. "Since African-American women don't seem to be getting the same subtypes of HPV with the same frequency, the vaccines aren't helping all women equally," said study author Adriana Vidal, Ph.D., assistant professor of obstetrics and gynecology at Duke University School of Medicine.

San Francisco Proposes Tax on Soda, Other Sugary Beverages
In an effort to curb the growing rate of obesity and obesity-related health issues, a San Francisco, California city supervisor has proposed a ballot measure that would impose a 2-cents-per-ounce tax on soda and other sugary beverages with at least 25 calories per ounce. This would be the first and strongest such city measure in the country, amounting to an additional 24 cents for a normal 12-ounce can of soda. Supervisor Scott Wiener said the tax proceeds, which he estimates would be $30 million annually, would go toward physical education and healthy lunch programs in city schools, as well as city parks, recreation programs and community health organizations. The California cities of Richmond and El Monte last year failed to enact similar taxes. A ballot measure requires a two-thirds majority to pass. "We know that this will be a long road," said Wiener. "This type of proposal has occurred in other cities and the beverage industry always comes out full guns blaring, so we're going to need to pull together to make sure that this wins."

Study: Young Cancer Patients at Increased Risk for Suicide
The stress of a cancer diagnosis means that teens and young adults who are diagnosed should be carefully monitored for behavior changes and other issues that could be a sign of suicidal thoughts, according to a new study in the Annals of Oncology. While there is an elevated risk of suicide for cancer patients of all ages, “because adolescents and young adults are still developing their coping strategies for stress, they may be more affected than adults when facing major adversity such as a cancer diagnosis," said lead researcher Donghao Lu, from the department of medical epidemiology and biostatistics at the Karolinska Institute in Stockholm, Sweden. Lu and his team found that Swedes ages 15-30 with a cancer diagnosis were at a 60 percent greater risk of suicide or attempted suicide, compared to people in the same age group but without cancer; in the first year after the diagnosis the risk was 150 percent higher. Lu said the findings indicate the need for greater communication and cooperation among medical professionals, psychological professionals, family members and social workers. Read more on cancer.
Electronic Laboratory Reporting Increasing
Federal agencies are reopening today after a 16 day shutdown and public health updates such as FluView from the Centers for Disease Control and Prevention are expected to come back online within the new few days. CDC’s last news release before the shutdown was on the increasing capability of laboratories to report findings to local and state health agencies electronically. The report was published in the most recent issue of Morbidity and Mortality Weekly Report (MMWR).
According to CDC, the number of state and local health departments receiving electronic reports from laboratories has more than doubled since 2005, however, progress is still needed. The MMWR report shows that only about a quarter of the nation’s labs are reporting electronically and that electronic reporting lags for some diseases behind others. For example, 76 percent of reportable lab results for general communicable diseases were sent electronically, compared to 53 percent of HIV results and 63 percent of results for sexually transmitted diseases.

District Laws and Policies Reduce Sugary Foods and Drinks at School Parties
Schools with a district policy or state law discouraging sugary foods and beverages were 2.5 times more likely to restrict those foods at school parties than were schools with no such policy or law, according to a new study published online in the Journal of Nutrition Education and Behavior.
Researchers at the University of Illinois at Chicago School of Public Health examined the linkages between state laws, district, and school-level policies for classroom birthday and holiday parties through surveys of more than 1,999 schools in 47 states.
About half the schools had either no restrictions or left the decision to teachers; one-third had school-wide policies discouraging sugary items; and fewer than 10 percent actually banned sweets during holiday parties or did not allow parties.
The study was supported by the Robert Wood Johnson Foundation. Read more on nutrition.
Children of Same Sex Marriages Less Likely to be Covered by Health Insurance
Children with same sex parents are less likely to have private health insurance than children with married opposite-sex parents, according to a recent study in Pediatrics. Using data from the 2008-2010 American Community Survey on children aged 0-17 years, the researchers found that 78 percent of children with married opposite-sex parents had private health insurance coverage, compared to 63 percent of children with same-sex fathers and 68 percent of those with same-sex mothers.
However, in states with legal same-sex marriage or civil unions, or in states that allowed second-parent adoptions, the disparities in private health insurance was lower for children of same-sex parents, suggesting that children of gay and lesbian households benefited from these policies. The American Academy of Pediatrics endorsed same-sex marriage in March. Read more on access to health care.
Study: Top Athletes Endorse Junk Food More Often Than Healthy Food
A new study of professional athletes’ food and beverage endorsements found that more often than not their paid support is given to products that are energy-dense and nutrient-poor, according to a new study in the journal Pediatrics. The study looked at 512 brands endorsed by 100 different athletes, finding that “Seventy-nine percent of the 62 food products in athlete-endorsed advertisements were energy-dense” and “93.4% of the 46 advertised beverages had 100% of calories from added sugar.” Denver Broncos player Peyton Manning and Miami Heat player LeBron James had the most endorsements for the energy-dense, nutrient-poor food and beverages. "I hope this paper inspires some reflection on the part of America's athletes and professional sports leagues, as well as all other celebrities for that matter,” said Center for Science in the Public Interest Executive Director Michael F. Jacobson, in a statement. Read more on nutrition.
U.S. Task Force Recommends Against Blood Pressure Screening for Kids, Teens
Despite recommendations from several expert groups, the U.S. Preventive Services Task Force is not recommending that health care professionals respond to the growing obesity crisis by screening children and teens for high blood pressure. The panel concluded that more study into the issue is needed, and that in the mean time there are other, known avenues toward lowering youth obesity and improving cardiovascular health. "We don't know if lowering blood pressure in youth leads to improved cardiovascular health in adulthood,” said panel member Kirsten Bibbins-Domingo, MD. “We also don't know the long-term benefits and harms for children and adolescents who initiate blood pressure medications when they are young. While there is much we don't know, we do know that eating a healthy diet, being active, and maintaining a normal weight are ways children and teens can improve their cardiovascular health."

Study: Tobacco Advertisements Connecting with Young Kids in Many Low-, Middle-income Countries
The global pervasiveness of tobacco advertisements means that most very young children in many low-and middle-income countries are familiar with cigarette brands, and nearly 70 percent of kids ages 5 and 6 can identify at least one cigarette logo, according to a new study in the journal Pediatrics. The study is from the Institute for Global Tobacco Control at the Johns Hopkins Bloomberg School of Public Health. The findings demonstrate the significant steps countries and public health organizations still need to take to limit the influence of tobacco ads. “Evidence-based strategies exist to reduce the ability of tobacco companies to market their products to children, such as implementing and enforcing bans on tobacco advertising, promotion and sponsorship,” said Joanna Cohen, PhD, co-author of the study and director on the institute. “Putting large picture warnings on the front and back of cigarette packs and requiring plain and standardized packaging, as Australia has done, also helps to reduce the attractiveness of cigarette packs among young children.” Read more on global health.
U.S. Youth Exercise, Diet Improved Over Past Decade
Exercise and dietary habits of U.S. kids and teenagers seems to have improved over the past decade, according to a new study in the journal Pediatrics. The study found that from 2001-2002 to 2009-2010, the average number of days per week being physically active for at least 60 minutes for sixth through tenth graders climbed from 4.3 to 4.5; the days eating breakfast before school climbed from 3 to 3.3; and hours per day watching television dropped from 3.1 to 2.4. The findings suggest that it takes time for public health efforts to translate into behavioral changes. "I would like to believe that all the public health efforts focusing on increasing physical activity and increasing fruit and vegetable consumption are having an effect, because that seems to be a pattern," said Ronald Iannotti, study author from the University of Massachusetts Boston. "The fact that (obesity) is leveling off, that's a surprise and a major change from the steady increase that we've seen over time.” Read more on pediatrics.
Study: Kids of Same-sex Couples Less Likely to Have Private Health Insurance
Children of same-sex parents are less likely to have private health insurance, although the rates improve in states that recognize same-sex marriages or unions, according to a new study in the journal Pediatrics. Approximately two-thirds of U.S. youth with same-sex parents have private health insurance, compared to approximately 78 percent of U.S. youth with married heterosexual parents. When accounting for additional factors such as parental incomes and education level, researchers determined that youth living with same-sex parents were as much as 45 percent less likely to have private health insurance than were youth living with married heterosexual parents. The findings indicate yet another public health benefit of same-sex marriage, as access to health insurance directly affects a child’s health; previous studies have shown a connection between legal unions and improved mental health for gay and lesbian adults. A likely cause for the disparity is the fact that employers have not had to extend coverage to an employee’s same-sex partner or that employee’s children. "I think we are going to see more and more research like this that shows how marriage-equality laws have far-reaching health consequences," said Richard Wight, a researcher at the University of California, Los Angeles, who was not a part of the study.

HHS: $67M for Expanded Preventive and Primary Care for 130,000 Americans
The U.S. Department of Health and Human Services (HHS) has awarded approximately $67 million for the creation of 32 new health service delivery sites to expand access to individuals, families and communities across the country. The sites will provide improved preventive and primary health care to more than 130,000 people. Another $48 million will go toward the approximately 1,200 existing centers. “Health centers have a proven track record of success in providing high quality health care to those who need it most,” said HHS Secretary Kathleen Sebelius. “New health center sites in some of the neediest communities in the country will provide access to health care for individuals and families who otherwise may have lacked access to high quality, affordable and comprehensive primary care services.” Read more on access to health care.
CDC: U.S. School Districts Seeing Improvements in Multiple Health Policies
U.S. school districts are seeing continued improvements in measures related to nutritional policies, physical education and tobacco policies, according to the U.S. Centers for Disease Control and Prevention (CDC). The findings are part of the 2012 School Health Policies and Practices Study, a periodic national survey assessing school health policies and practices at the state, district, school, and classroom levels. "Schools play a critical role in the health and well-being of our youth," said CDC Director Tom Frieden, MD, MPH. "Good news for students and parents – more students have access to healthy food, better physical fitness activities through initiatives such as ‘Let’s Move,’ and campuses that are completely tobacco free."
Among the key findings:
- The percentage of school districts that allowed soft drink companies to advertise soft drinks on school grounds decreased from 46.6 percent in 2006 to 33.5 percent in 2012.
- Between 2006 and 2012, the percentage of districts that required schools to prohibit junk food in vending machines increased from 29.8 percent to 43.4 percent.
- The percentage of school districts that required elementary schools to teach physical education increased from 82.6 percent in 2000 to 93.6 percent in 2012.
- The percentage of districts with policies that prohibited all tobacco use during any school-related activity increased from 46.7 percent in 2000 to 67.5 percent in 2012.

Poor Oral Health Linked to Increased Risk for Oral HPV Infection
Poor oral health is associated with increased risk of the oral human papillomavirus (HPV) infection responsible for as many as 80 percent of oropharyngeal cancers, according to a new study in the journal Cancer Prevention Research. Researchers found that people who reported poor oral health had a 56 percent higher prevalence oral HPV, people with gum disease had a 51 percent higher prevalence and people with dental problems had a 28 percent higher prevalence. “The good news is, this risk factor is modifiable—by maintaining good oral hygiene and good oral health, one can prevent HPV infection and subsequent HPV-related cancers.” said Thanh Cong Bui, MD, postdoctoral research fellow at the University of Texas School of Public Health. Other factors also increased the risk, such as being male, smoking tobacco or using marijuana. Read more on cancer.
Study: Hospital Pediatric Readmission Rates Not an Effective Measure of Quality of Care
Hospital readmission rates for children are not necessarily an effective measurement of the quality of care, according to a new study in the journal Pediatrics. "As a national way of assessing and tracking hospital quality, pediatric readmissions and revisits, at least for specific diagnoses, are not useful to families trying to find a good hospital, nor to the hospitals trying to improve their pediatric care," study author Naomi Bardach, MD, an assistant professor of pediatrics at the University of California, San Francisco, Benioff Children's Hospital. "Measuring and reporting them publicly would waste limited hospital and health care resources." After analyzing 30- and 60-day readmission rates for seven common pediatric conditions, researchers found that at 30 days readmission for mood disorders was most common, at 7.6 percent, followed by 6.1 percent for epilepsy and 6 percent for dehydration. Readmission rates for asthma, pneumonia, appendicitis and skin infections were all below 5 percent. Bardach said the low rates leave “little space for a hospital to be identified as having better performance.” Further study could improve the way readmission rates are utilized to assess the quality of pediatric care.

U.S. Circumcision Rate Down 10 Percent over Past Three Decades
The circumcision rate of U.S. newborns dropped approximately 10 percent from 1979 to 2010, according to new date from the National Center for Health Statistics. In 2010 about 58.3 percent of boys born in U.S. hospitals were circumcised; the rate was 64.5 percent in 1979. While beginning as a religious ritual, the use of circumcision expanded due to potential health benefits such as reduced risk of urinary tract infections in infants and reduced risk of sexually transmitted diseases. Last August the American Academy of Pediatrics said that these benefits outweigh any risks. However, the procedure also has many opponents. While the report did not go much into the reasons for the decline, possible explanations include the fact that Medicaid has stopped paying for circumcisions in 18 U.S. states, some insurers are not covering procedures without strong medical justifications and shorter hospital stays for new mothers means some circumcisions are performed later as outpatient procedures.

Eating Fruit Helps Prevent Certain Aneurysms
An apple—or any other fruit—a day may lower a person’s risk of an abdominal aneurysm, according to a new study in the journal Circulation. The thirteen year study of 80,000 people ages 48 to 64 in Swede found that people who reported eating more than two servings of fruit daily had a 25 to 31 percent lower risk of abdominal aortic aneurysm than those who ate little or no fruit. High levels of antioxidants in fruits might protect against abdominal aortic aneurysm by preventing oxidative stress that can promote inflammation, according to the researchers, who found no similar association for vegetables, which are also rich in antioxidants, but may lack some of the components in fruits. However, vegetables remain important to a person’s diet, say the study authors. Combined with fruit they may help decrease the risk of cardiovascular diseases, type 2 diabetes, high blood pressure and several cancers. The American Heart Association advises the average adult to eat four to five servings each of fruits and vegetables daily, based on a 2,000 calorie diet. Read more on nutrition.
Study: CTE Victims First Present with Impaired Mood or Thinking
People suffering from chronic traumatic encephalopathy (CTE)—a neurodegenerative disease that can only be diagnosed after death—will likely first begin exhibiting either impaired behavior and mood or impaired memory and thinking abilities, according to a new study in the journal Neurology. CTE is characterized by impulsivity, depression and erratic behavior. "The study itself is relatively preliminary, [but] we found two relatively distinct presentations of the disease," said study co-author Daniel Daneshvar, a postdoctoral researcher at the university's Center for the Study of Traumatic Encephalopathy. "So little is known about the clinical presentation of CTE that anything we found is not necessarily surprising, simply because there's a dearth of information about CTE." Researchers emphasized that far more study is needed. CTE and other head trauma have become increasingly prominent issues over the last several years, with cases linked to both sports injuries and battlefield injuries. There is currently a lawsuit by almost 4,000 former NFL players claiming the league did not properly inform them of the dangers of concussions or adequately protect their health.
