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.

Hypertension Often Untreated in U.S. Hispanic Community
A new study in the American Journal of Hypertension finds that there is too little recognition and control of hypertension among the Hispanic population of the United States.
The new data comes from the Hispanic Community Health Study/Study of Latino, a longitudinal study of 16,415 Hispanics/Latinos, ages 18 to 74 years from four communities in the U.S. (Bronx, Chicago, Miami, and San Diego). Measures including hypertension levels and whether patients were on hypertension medications were collected between 2008 and 2011 and then followed up last year.
The study also found that the prevalence of hypertension in the Hispanic community increased with age, and was highest among those with Cuban, Puerto Rican, and Dominican backgrounds.

Study: Better Boundaries, Enforcing Rules Can Improve Kids’ Sleep Health
Parents can improve their children’s sleep habits and overall health by setting boundaries around electronics use, enforcing rules and setting a good example, according to new findings from the National Sleep Foundation’s (NSF) Sleep in America poll. The annual study began in 1991, with the 2014 poll focusing on sleep practices and beliefs of the modern family with school-aged children. “For children, a good night’s sleep is essential to health, development and performance in school,” said Kristen L. Knutson, PhD, University of Chicago. “We found that when parents take action to protect their children’s sleep, their children sleep better.” The NSF recommends that children ages 6-10 get 11 hours of sleep per night, although the poll found that parents estimate their kids in that age group only get about 8.9 hours. The poll also found averages of 8.2 hours for kids ages 11-12, 7.7 hours for ages 13-14 and 7.1 hours ages 15-17; NSF recommends between 8.5 and 9.5 hours for each of those groups.

Stress of Racism Tied to Obesity in Black Women
Frequent experiences of racism are associated with a higher risk of obesity among African-American women, according to a new study in the American Journal of Epidemiology. Researchers analyzed data from the Black Women's Health Study, a longitudinal study of approximately 59,000 African-American women who were tracked beginning in 1995, finding that the psychosocial stress associated with long-term experience with racism can result in dysregulation of neuroendocrine functions that influence the accumulation of excess body fat. Yvette C. Cozier, DSc, MPH, assistant professor of epidemiology at Boston University who led the analyses, said in a release that work-place- and community-based programs to combat racism and interventions to reduce racism-induced stress could help prevent and combat obesity in high-risk communities. Approximately half of African-American women are obese, which raises their risk factors for cardiovascular diseases, type 2 diabetes, orthopedic problems, and death. Read more on health disparities.
CDC: H1N1 Flu Killing at Epidemic Levels
The H1N1 flu virus has been killing at epidemic levels since mid-January, according to new data from the U.S. Centers for Disease Control and Prevention (CDC). While flu is known to disproportionately affect the very young and very old, this strain—also known as the swine flu and the cause of the 2009 global pandemic that killed tens of thousands—has so far caused 243 deaths of residents younger than 65 this year in California alone, with an additional 41 unconfirmed cases. In the 2012-13 season there were 26 deaths at this point and in the 2011-12 season there were nine. According o the CDC the average age of someone diagnosed with flu this season is 28.5 years. “These severe flu outcomes are a reminder that flu can be a very serious disease for anyone, including young, previously healthy adults,” CDC spokesman Jason McDonald said to The Washington Post.

Teens Who Text About Condoms, Birth Control More Likely to Use Them
Teens who talk about condoms and other types of birth control over text message and other technology are more likely to use them, according to a new study in the Journal of Adolescent Health. Researchers studied 176 high school juniors and seniors, finding that half of the 64 who reported being sexually active also failed to use condoms consistently. According to the U.S. Centers of Disease Control and Prevention, close to 40 percent of the 47 percent of high school students who reported having sex did not use a condom the last time. However, the study found that students who texted or used other private electronic technology to discuss condoms or other forms of birth control were approximately four times more likely to use them. It also found that the odds of consistently using condoms doubled among students reporting discussions of pregnancy or sexual limits. "Although prior research and media attention has focused on the risks of technology use, like sexting, we found that adolescents might also use electronic tools to communicate about ways they might promote their sexual health," said study lead author Laura Widman, who studies adolescent sexuality at the University of North Carolina at Chapel Hill. "It's not all about risky behavior. It might be another way that teens can have these conversations that can be a little bit awkward.” Read more on sexual health.
Study: Average Obese Woman Gets Only One Hour of Vigorous Exercise Each Year
The average obese woman in the United States gets only one hour of vigorous exercise each year, and the average obese man gets only 3.6 hours, according to a new study in Mayo Clinic Proceedings. The study utilized the results of a 2005-2006 government survey of adults aged 20 to 74, which covered areas such as weight, diet and sleep patterns of the nearly 2,600 adults and use accelerometer devices to track their movements. The study defined "vigorous" exercise as fat-burning activities such as jogging and jumping rope. “They're living their lives from one chair to another," said Edward Archer, a research fellow with the Nutrition Obesity Research Center at the University of Alabama at Birmingham. "We didn't realize we were that sedentary. There are some people who are vigorously active, but it's offset by the huge number of individuals who are inactive." According to the U.S. Centers for Disease Control and Prevention (CDC), approximately one in three U.S. adults is obese, which increases the risk of cardiovascular problems such as heart disease and stroke, diabetes and some cancers.

Labor Department Announces Grants to help Adults Transition from Prison to Workforce
The U.S. Department of Labor has announced close to $30 million in grants to help men and women participating in state or local prison work-release programs get the job skills needed for “in demand” jobs. Grants will be awarded to implementing partners that provide qualifying services in areas with high-poverty and high-crime rates, including communities that have a large proportion of returning citizens that typically experience higher rates of recidivism.

Combining Online Games, Betting and Social Interaction Can Help People Lose Weight
A study by researchers at the Miriam Hospital in Providence, Rhode Island finds that a web-based commercial weight loss program that pairs financial incentives with social influence resulted in significant weight loss for many of the study participants. The results were published in JMIR Serious Games.
Players joined a game to lose weight while betting money on themselves and had four weeks to lose four percent of their starting weight. At the end of week four, all players who lost at least four percent of their initial body weight were deemed winners and split the pool of money collected at the start of the game. The researchers studied nearly 40,000 players over seven months and found that winners lost an average of 4.9 percent of their initial body weight and won an average of $59 in four weeks. Factors associated with winning the game included betting more money, sharing on Facebook, completing more weigh-ins, and engaging in more social interactions with the other players.

New SAMHSA Guide Provides Resources to Help Families Support Their LGBT Children
The Substance Abuse and Mental Health Services Administration (SAMHSA) has released a Resource Guide to help health care and social service practitioners provide guidance to families on how to support their children who are coming out or identifying themselves as lesbian, gay, bisexual and transgender (LGBT). According to SAMHSA, with greater access to more information about sexual orientation, gender identity and LGBT resources through the internet and other media, more young people have been coming out than ever before and at younger ages, and the family-oriented approach offered by the guide can provide useful information during a critical period.

A surprising piece of information at this week’s AcademyHealth National Health Policy Conference came during a session on what additional evidence is needed to move forward in the prevention and treatment of obesity. Linda Billheimer, PhD, deputy director of the health, retirement and long term analysis office at the Congressional Budget Office, said that one weakness of some obesity clinical trials is that they may not reflect the number of people who drop out during the trial. For example, while a study may show the success rate for 400 participants, it may not account for the number of people who left the trial and have not lost weight—or even gained weight—since their trial participation.
Billheimer noted that retaining patients can be difficult because people who plateau are often frustrated, which can combine with other reasons to lead them to leave.
Attempting to keep participants in the trial can be critical because the modality offered may be a strong opportunity for the participants to lose weight, since the trials often have novel approaches. There is also the support from the clinical trials team. Researchers at the session noted that trial funders might add criteria to the trial on follow up for participants who withdraw to possibly increase participation time among a larger group of patients.
Recent novel obesity trials listed by the U.S. National Institutes of Health on ClinicalTrials.gov include
- A trial comparing low and high financial incentives for weight loss
- Using virtual reality to help trial participants work on weight loss
- Community based obesity prevention among black women
