OECD: Economic Crisis Contributed to Global Obesity Crisis
More people than not in the member countries of the Organization for Economic Co-operation and Development (OECD) are obese, with the economic crisis that began in 2008 contributing even more to the overall increase in body weight and obesity, according to a new OECD report. The analysis found that many of the people and families in the countries hit hardest by the economic crisis were forced to turn to less expensive—but also less healthy—food. For example, from 2008-2009 households in the United Kingdom decreased their food expenditure by 8.5 percent in real terms, while also increasing the average calorie density of purchased foods by 4.8 percent.
Among the other findings:
- One in 5 OECD children are overweight or obese
- The obesity epidemic has spread further in the past five years, but rates have been increasing at a slower pace than before
- People with less education and lower socio-economic status are more likely to be obese, and the gap is generally larger in women
- A growing number of countries have adopted policies to prevent obesity from spreading further

Study: 1 in 5 Medicare Patients Experience Medical Injuries
Approximately 20 percent of Medicare patients experience medical injuries, which are often not linked to any underlying disease or condition, according to a new study in the journal Injury Prevention. Typical injuries include being given the wrong medication, having an allergic reaction to a medication, or receiving any treatment that led to more complications of an existing medical problem. Using data on more than 12,500 Medicare patients who made claims between 1998 and 2005, researchers found that 19 percent experienced at least one adverse medical event and 62 percent of the injuries took place during outpatient care. The highest risks were scene in older people, men and those from lower-income backgrounds. "These injuries are caused by the medical care or management rather than any underlying disease," said lead researcher Mary Carter, director of the Gerontology Program at Towson University in Maryland. "To really improve our ability to prevent these types of adverse events, we have to focus at least as much on outpatient care as we do on inpatient care." Read more on injury prevention.
Salmonella Outbreak Causes an Additional 50 Cases; Total Now at 574
With an additional 50 cases, the salmonella outbreak linked to Foster Farms chicken that began in March 2013 now has sickened a total of 574 people, according to the U.S. Centers for Disease Control and Prevention (CDC). The CDC estimates there have been an average of eight new cases per week since an April report on the drug-resistant Salmonella Heidelberg. Thirty-seven percent of the cases have led to hospitalization and about 13 percent have developed blood infections, which is three times higher than what’s seen with typical salmonella infections.

Faster Mass Vaccination Response Could Save Lives, Costs in a Flu Pandemic
A faster response of mass vaccinations after the start of a severe flu outbreak would save both lives and health care costs, according to a new study in Annals of Internal Medicine. Researchers created a computer model of a how an outbreak of H7N9 or H5N1 would affect a U.S. metropolitan city with characteristics similar to New York City, depending on when public health officials were able to vaccinate 30 percent of the population. They determined that reaching that vaccination target in 12 months would mean 48,254 persons would die; at 9 months would save an additional 2,365 lives; at 6 months would save an additional 5,775 lives and $51 million at a city level; and at 4 months would save an additional 5,633 lives and $50 million.

Study: Current Weight at 25 a Better Indicator of Later Obesity Risk than Duration of Obesity
In a study of the relationship between body mass index (BMI) at age 25, obesity later in life and biological indicators of health, researchers determined current weight—and not the duration of obesity—was a more effective indicator of cardiovascular and metabolic risk, according to a new study in the American Journal of Preventive Medicine. They did also note that people who were obese by age 25 were in fact at higher risk of more severe obesity later in life. Using data from the 1999-2010 U.S. National Health and Nutrition Examination Survey (NHANES), the study found that men who were obese at age 25 had a 23.1 percent estimated probability of class III obesity (BMI greater than 40) after age 35, compared to a 1.1 percent chance for men of a normal weight at age 25. For women who were obese at age 25 the risk of later class III obesity was 46.9 percent, compared to only 4.8 percent for women of a normal weight. “This is good news in some respects, as overweight and obese young adults who can prevent additional weight gain can expect their biological risk factors to be no worse than those who reach the same level of BMI later in life,” said study lead author Jennifer B. Dowd, MD, associate professor, epidemiology and biostatistics, City University of New York (CUNY) School of Public Health, Hunter College. Read more on obesity.
Higher High School GPAs Linked to Greater Earnings in Adulthood
A one-point increase in high school grade point average (GPA) can raise annual earnings in adulthood by approximately 12 percent for men and 14 percent for women, according to a new study in the Eastern Economic Journal. Researchers also determined that a 1-point increase in GPA increased the likelihood of completing college from 21 percent to 42 percent for both genders. “Conventional wisdom is that academic performance in high school is important for college admission, but this is the first study to clearly demonstrate the link between high school GPA and labor market earnings many years later,” said Michael T. French, director of the Health Economics Research Group (HERG) in the Department of Sociology at the UM College of Arts and Sciences, and corresponding author of the study, adding, “High school guidance counselors and teachers can use these findings to highlight the importance of doing well in high school for both short term (college admission) and longer term (earnings as an adult) goals.” Read more on education.
Tornadoes Kill At Least 17 in South Central U.S. Over the Weekend
Multiple tornadoes, damaging winds and hail storms over the weekend resulted in 17 deaths in Arkansas and Oklahoma, according to reporting by the Weather Channel. More severe weather is expected in the South and Midwest through Wednesday. According to reporting by Reuters, the hardest hit area was Faulkner County in Arkansas, where 10 people died and cars and homes were destroyed. The Red Cross has opened several shelters in the area.

Study: Almost Half of Homeless Men Previously Suffered a Traumatic Brain Injury
Almost half of all homeless men who took part in a study by researchers at St. Michael’s Hospital in Toronto had suffered at least one traumatic brain injury (TBI) in their lives and 87 percent of those injuries occurred before the men lost their homes, according to the study authors. Some men suffered more than one TBI and the researchers found that assaults accounted for 60 percent of the injuries; sports and recreation accounted for 44 percent; and car accidents and falls accounted for 42 percent.
The fact that so many homeless men suffered a TBI before losing their home suggests such injuries could be a risk factor for becoming homeless, said lead researcher Jane Topolovec-Vranic, PHD, a clinical researcher in the hospital’s Neuroscience Research Program. Topolevec-Vranic said the study underscores the need to monitor young people who suffer TBIs such as concussions for health and behavioral changes. In men under age 40, falls from drug/alcohol blackouts were the most common cause of traumatic brain injury, while assault was the most common in men over 40 years old. The study was published in the journal CMAJ Open. Read more on injury prevention.
People on Statins More likely to Eat Foods that Can Lead to Obesity Related Illnesses
A new study led by researchers from UCLA suggests that people who took statins in 2009–10 were consuming more calories and fat than those who used statins 10 years earlier. There was no similar increase in caloric and fat intake among non-statin users during that decade according to the study in JAMA Internal Medicine. "We believe that this is the first major study to show that people on statins eat more calories and fat than people on those medications did a decade earlier," said the study's primary investigator, Takehiro Sugiyama, a visiting scholar at the David Geffen School of Medicine at UCLA. "Statins are used by about one-sixth of adults. We may need to reemphasize the importance of dietary modification for those who are taking these medications...”
The study authors used data from the National Health and Nutrition Examination Survey to compare fat and caloric intake among statin users and non-users in 1999–2000 and 2009–10. They found that caloric intake among statin users had risen by 9.6 percent over that decade and that fat consumption had jumped by 14.4 percent. In contrast, caloric and fat intake by non-statin users did not change significantly during the 10-year period. Read more on obesity.
FDA Proposes Rule for Regulation of E-cigarettes
The U.S. Food and Drug Administration (FDA) today released its long-expected proposed new rule that would expand its authority to include the regulation of e-cigarettes. Under the proposed rule, FDA would also be able to regulate products that meet the statutory definition of a tobacco product, including cigars, pipe tobacco, nicotine gels, waterpipe (or hookah) tobacco and dissolvables not already under the agency’s authority. “This proposed rule is the latest step in our efforts to make the next generation tobacco-free,” said U.S. Department of Health and Human Services Secretary Kathleen Sebelius.

Study: 1 in 13 U.S. Kids Take Prescription Drugs for Emotional or Behavioral Issues
One in 13 U.S. schoolchildren take medication for emotional or behavioral issues, with more than half of the parents of these children reporting that the drugs have helped “a lot,” according to a new report from the U.S. National Center for Health Statistics. Only about one in five parents said the medication had not helped at all. The report also found that among youth ages 6-17 years, a higher percentage of children insured by Medicaid or the Children's Health Insurance Program used such prescribed medication than did children with private health insurance or no health insurance, and that a higher percentage of children in families having income below 100 percent of the poverty level used prescribed medication for emotional or behavioral difficulties than did children in families at 100 percent to less than 200 percent of the poverty level.

Study: Genetic Risk for Obesity Rises as Kids Age
The genetic risk for obesity rises as children age, according to a new study in the journal Obesity. Researchers analyzed data on 2,556 pairs of twins in England and Wales at ages 4 and 10, finding that the influence of genetic variants rose as they got older, with genes accounting for about 43 percent of the difference in size among the four-year-olds, but 82 percent of the difference at the age of 10. "Our results demonstrate that genetic predisposition to obesity is increasingly expressed throughout childhood," said study co-leader Clare Llewellyn, MD, of the department of epidemiology and public health at University College London, in a release. "This underlines the importance of intervening at an early age to try to counteract these genetic effects and reduce childhood obesity.” Read more on obesity.
Study: Monday the Best Time to ‘Reset’ and Improve Personal Health Regimens
People are more likely to think about their health earlier in the week, which could help researchers and officials determine how to better improve public health strategies, according to a new study in the American Journal of Preventive Medicine. Researchers from San Diego State University (SDSU), the Santa Fe Institute, Johns Hopkins University and the Monday Campaigns analyzed Google searches that utilized the term “healthy” and were health-related in the United States from 2005 to 2012, finding searches for healthy topics were 30 percent more frequent at the beginning of the week than later in the week; Saturday saw the fewest searches. The findings correspond with previous research indicating Mondays offered the opportunity for a “heath reset”—a chance to get back into healthy habits. "Many illnesses have a weekly clock with spikes early in the week," said SDSU's John W. Ayers, lead author of the study. "This research indicates that a similar rhythm exists for positive health behaviors, motivating a new research agenda to understand why this pattern exists and how such a pattern can be utilized to improve the public's health.” Read more on prevention.
Despite Recommendations Against, Codeine Still Prescribed to Many Kids During ER Visits
Codeine is often prescribed by emergency room physicians to treat coughs and other pains for children, even though the powerful opioid is not recommended for use in children by groups such as the American Academy of Pediatrics (AAP) and American College of Chest Physicians (ACCP), according to a new study in the journal Pediatrics. For the new study, the researchers used data from 189 million ER visits by children and teens between the ages of three and 17 years old. The visits took place between 2001 and 2010. Researchers from the University of California, San Francisco analyzed data from 189 million ER visits for youth ages 3-17, finding that while emergency room prescriptions were down slightly from 2001 to 2010, as many as 877,000 children are still taking the drug each year. Codeine can slow breathing and breaks down differently in children of different ethnicities, increasing the chance of overdose. Read more on prescription drugs.
Rates of Childhood Obesity Keeps Rising, Especially Among the Most Obese
A recent study out of the University of North Carolina (UNC) finds that childhood obesity is up for all classes of obesity in U.S. children over the past 14 years, with more severe forms of obesity—a body mass index (BMI) 120 to 140 percent higher than the averages—seeing the greatest increase. The study appeared in JAMA Pediatrics. “An increase in more severe forms of obesity in children is particularly troubling,” said Asheley Cockrell Skinner, PhD, lead author of the study and assistant professor of pediatrics in the UNC School of Medicine, in a release. “Extreme obesity is more clearly associated with heart disease and diabetes risk in children and adolescents, and is more difficult to treat.” Researchers analyzed data on 26,690 children ages 2-19 years from 1999 to 2012 collected as part of the National Health and Nutrition Examination Survey (NHANES).

Urban Gardeners May Be Unaware of Harmful Soil Contaminants
In their quest to consume healthier foods, urban gardeners may actually be unaware of the presence of soil contaminants and how to deal with the issue, putting both gardeners and consumers at risk, according to a new study in PLOS One. Potential contaminants include heavy metals, petroleum products and asbestos, which can result when urban soil is near pollution sources, such as industrial areas and roads with heavy traffic. “Our study suggests gardeners generally recognize the importance of knowing a garden site’s prior uses, but they may lack the information and expertise to determine accurately the prior use of their garden site and potential contaminants in the soil,” said Keeve Nachman, PhD, senior author of the study and director of the Food Production and Public Health Program with the Johns Hopkins Center for a Livable Future. “They may also have misperceptions or gaps in knowledge about how best to minimize their risk of exposure to contaminants that may be in urban soil.” Read more food safety.
Study: 1 in 10 U.S. Adults Have Diabetes
Nearly one in 10 U.S. adults had diabetes in 2010, nearly double the percentage a little more than two decades ago, in 1988, according to a new study in the Annals of Internal Medicine. The study determined that 21 million American adults—or 9.3 percent of all American adults—had either type 1 or type 2 diabetes in 2010. As many as 95 percent of diabetes cases are type 2 cases. "This study also highlights that the increase in diabetes really tracks closely with the epidemic of obesity,” said Elizabeth Selvin, the study's lead author and an associate professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health. “The diabetes epidemic is really a direct consequence of the rise in obesity.” However, the report did find that cases of undiagnosed diabetes were down, indicating new screen techniques are effective. It also found that overall blood sugar control was improved. Read more on obesity.
U.S. Health Care Costs Climbed 3.2% in 2013, to $329.2 Billion
The cost of new medicines, price increases on some branded drugs and patent expirations helped cause the first rise in the overall cost of health services in the United States in three years, according to a new report from IMS Health Holdings Inc., a health care information company. Americans spent a total of $329.2 billion on health services in 2013, up from 3.2 percent from 2012, which had seen a 1 percent decline. However, the report noted that expanded use of cheaper generic drugs—86 percent of all prescription drugs—did help costs from rising even higher. Read more on access to health care.
CDC Identifies Rare U.S. Case of Lassa Fever
A severe viral disease common in West Africa has been confirmed in a person returning to the United States from the region, according to the U.S. Centers for Disease Control and Prevention (CDC) and the Minnesota Department of Health (MDH). The patient was admitted to a Minnesota hospital for Lassa fever on March 31, with the CDC confirming diagnosis on April 3 and the patient now recovering and in stable condition. The last case of Lassa fever in the United States, of which there have been seven confirmed and all related to travel, was in Pennsylvania in 2010. The virus is not transmitted through direct contact with a sick person’s blood of bodily fluids and cannot by transmitted by casual contact; there are up to 300,000 cases and 5,000 deaths each year in West Africa. “This imported case is a reminder that we are all connected by international travel. A disease anywhere can appear anywhere else in the world within hours,” said CDC Director Tom Frieden, MD, MPH. Read more on infectious disease.
Public Health Officials in Developing Countries Use Social Marketing to Promote Health Behaviors
Public health officials in developing countries are successfully using social marketing strategies to educate people about the importance of behaviors related to water and sanitation, according to a new study in the journal Social Science & Medicine. In a systematic review of 32 studies, researchers led by W. Douglas Evans, PhD, a professor of prevention and community health at Milken Institute School of Public Health at the George Washington University, looked at how public health officials utilized social marketing tools such as door-to-door visits and public education campaigns for school children to promote behaviors such as regular hand washing and water purification.

Depression, Anxiety Linked to Poor Diabetes Management
Depression and anxiety can be significant impediments to proper management of diabetes, according to a new study in the journal BioMed Central. Researchers from The University of Texas School of Public Health examined 500 Mexican-American adults from the Cameron County Hispanic Cohort in Brownsville, Texas, each of whom had been diagnosed diabetes and were taking medication for diabetes. Each t was interviewed about symptoms of depression and anxiety, and researchers also took measurements for body mass index (BMI), waist circumference, physical activity, fasting glucose and average blood sugar levels over time. “Unfortunately, greater depression and anxiety are associated with higher BMI and greater waist circumference, both indicators of obesity, as well as engaging in less physical activity and having less favorable indicators of glycemic control,” said Darla Kendzor, PhD, principal investigator and assistant professor at the School of Public Health Dallas Regional Campus, part of The University of Texas Health Science Center at Houston. Eighty one percent of Mexican-Americans are obese or overweight nationwide, with a nationwide diabetes rate of 16.3 that climbs to 30 percent for those who live along the U.S.-Mexico border.

Study Finds Many Older Adults Often Not Prepared for Disasters
A recent University of Iowa study finds that, compared to younger adults, older adults are more vulnerable when natural disasters, hit yet most U.S. adults ages 50 and older may not be prepared for a serious flood, earthquake, tornado, or other natural disaster. The report is based on a 2010 survey that was part of the Health and Retirement Study, which collects social, economic, and health information on adults age 50 and older in the United States. The survey did not include older adults living in nursing homes or other institutional settings. Among the findings:
- Only about one-third of the 1,304 adults interviewed said they had participated in an educational program or read information on how to prepare for a disaster.
- Fewer than 25 percent had an emergency plan in place, although the same percentage lived alone.
- Almost one-third reported being disabled or in fair or poor health.
“Our analysis underscores that older adults living at home often have special needs and situations that put their health and safety at risk in the face of natural disasters,” said Tala Al-Rousan, MD, the study’s primary author and a graduate student in epidemiology at the UI College of Public Health. “The oldest respondents, 80- to 90-year-olds, were significantly less prepared than 65- to 79-year-olds.”

Healthy Foods Can Increase Concession Stand Sales A new small study by researchers at the University of Iowa found that adding healthy foods to a football game concession stand appears to increase sales. The researchers asked a college club to add healthy foods such as apples and string cheese to its concession stand menu open during football season, as well as put healthier ingredients into other items including nachos and popcorn. Sales rose four percent over the previous year, and the healthier foods making up almost ten percent of sales. The study was published in the Journal of Public Health. Read more on nutrition.
Study: Gastric-Bypass Surgery Linked to Remission of Type 2 Diabetes
People who undergo gastric-bypass surgery to deal with their weight are more likely to see their type 2 diabetes go into remission without medication that are people who undergo a sleeve gastrectomy, according to a new study in the New England Journal of Medicine. "One-third [of patients] in the gastric bypass group had remission of diabetes—meaning they had normal blood sugar control—and a quarter of the people in the sleeve gastrectomy group had remission of type 2 diabetes," said study co-author Sangeeta Kashyap, MD, an endocrinologist at the Cleveland Clinic's Endocrinology & Metabolism Institute, according to HealthDay. "These effects are real, and they're persistent for at least three years. Essentially, these patients have had a vacation from diabetes for three years." The study included 150 people with type 2 diabetes, with an average age of 49 and two-thirds female. Read more on obesity.
Overweight Teens Should Start Healthy Eating by Cutting Down on Salt
Overweight or obese teenagers who eat lots of salty foods shows signs of faster cell aging, according to research presented at the American Heart Association’s Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014. Previous research found that protective ends on chromosomes (telomeres) naturally shorten with age, but the process is accelerated by smoking, lack of physical activity and high body fat. This study is the first to examine the impact of sodium intake on telomere length.
In the study, 766 people ages 14-18 were divided into the lowest or highest half of reported sodium intake. Low-intake teens consumed an average 2,388 mg/day, compared with 4,142 mg/day in the high-intake group. Both groups consumed far more than the 1,500 mg/day maximum (about 2/3 teaspoon of salt) recommended by the American Heart Association. After adjusting for several factors that influence telomere length, researchers found that in overweight/obese teens, telomeres were significantly shorter with high-sodium intake. In normal weight teens, telomeres were not significantly different with high-sodium intake.
“Even in these relatively healthy young people, we can already see the effect of high sodium intake, suggesting that high sodium intake and obesity may act synergistically to accelerate cellular aging,” said Haidong Zhu, MD, PhD, lead author of the study and assistant professor of pediatrics at Medical College of Georgia, Georgia Regents University in Augusta, Ga. “Lowering sodium intake may be an easier first step than losing weight for overweight young people who want to lower their risk of heart disease. The majority of sodium in the diet comes from processed foods, so parents can help by cooking fresh meals more often and by offering fresh fruit rather than potato chips for a snack.” Read more on heart health.
DOT Awards Grants to Improve Transportation for American Indian and Alaska Native Tribes
The U.S. Department of Transportation is awarding $5 million to 42 American Indian and Alaska Native tribes in 19 states for projects to improve transit service, in addition to $25 million in funds announced recently to help improve public transit service on rural tribal lands and better connect tribal members and other residents with jobs, education, and other opportunities.
“We fully recognize that residents on tribal lands and in surrounding communities often face significant transportation challenges, as many cannot afford to own a vehicle, or fill the tank, and yet must travel long distances to reach basic services,” said Federal Transit Administration head Therese McMillan. “We want to ensure that everyone who needs a ride to earn a paycheck, attend school, see the doctor, or buy groceries has that opportunity.” Read more on transportation.
Health Providers Should Prescribe Sleep for People with Metabolic Disorders
A new study in The Lancet Diabetes & Endocrinology finds that insufficient or disturbed sleep is associated with metabolic disorders such as type 2 diabetes and obesity, and addressing poor quality sleep should be a target for the prevention—and even treatment—of the disorders. According to the study authors, addressing some types of sleep disturbance—such as sleep apnea—may have a directly beneficial effect on patients' metabolic health, but a far more common problem is people simply not getting enough sleep, particularly due to the increased use of devices such as tablets and online games. The authors say that early studies are starting to provide evidence that there is a direct causal link between loss of sleep and the body's ability to metabolize glucose, control food intake, and maintain its energy balance.

Study: Prescriptions for Opioids Steadying After Nearly Tripling over Two Decades
After nearly tripling from 1991 to 2010—from 76 million annually to 210 million annually—prescriptions for opioid analgesics in the United States are stabilizing, according to a new reporting in the journal Public Health Reports. Researchers at Columbia University’s Mailman School of Public Health attributed much of the success to stopping the soaring number of prescriptions to state-implemented prescription drug monitoring programs (PDMPs). “We found that PDMPs administered by state health departments appeared to be more effective than those administered by other government agencies, such as the bureau of narcotics and the board of pharmacy, ” said senior author Guohua Li, MD, professor of epidemiology and director of the Center for Injury Epidemiology and Prevention.

Study: Mother’s Monitoring of Kids’ Media Consumption Tied to Changes in Weight
Children whose mothers pay more attention to their kids’ media habits—how much time they spend watching television or playing video games—are more likely to weigh less than children who do not receive the same sort of supervision, according to a new study in JAMA Pediatrics. Researchers found that kids with mothers who monitored their media consumption were thinner at age seven and gained less weight over the following few years. While the authors said they cannot point to the exact reason for the relationship, possibilities include vigilant mothers who encourage more physical activity and the fact that the kids are exposed to fewer food advertisements. The study used a questionnaire to asses 112 mothers, 103 fathers and their 213 children; media monitoring by fathers was not linked to weight gain or loss. Stacey Tiberio, the study's lead author from the Oregon Social Learning Center in Eugene, told Reuters Health that the results emphasize the important role that early adolescence plays with weight. "It's basically a one-way door," she said. "If you are obese by middle childhood, you have an increased likelihood of staying in that group." Read more on obesity.
Finding Unlisted Milk Protein, FDA Announces Recall of Certain Simply Lite Chocolate Products
The U.S. Food and Drug Administration (FDA) has announced a recall of certain lots of Simply Lite brand dark chocolate bars after finding significant amounts of milk protein, which the product does not list as an ingredient. FDA testing found more than 3,500 parts per million of milk protein in single 3-ounce bars of the chocolate—or the equivalent found in about 4 teaspoons of whole milk. People with milk allergies or sensitivity to milk could have serious or even life-threatening reactions to the product. Consumers with questions about food safety can contact the FDA at 1-888-SAFEFOOD Monday through Friday between 10 a.m. and 4 p.m. Eastern Daylight Time.
