Individuals with chronic occupational exposure to lead have an 80 percent higher odds of developing Amyotrophic Lateral Sclerosis (ALS) than individuals who do not have the exposure. Those are the findings of a recently published meta-analysis of 13 studies of individuals with “Lou Gehrig’s disease" (ALS). The authors, funded by the Public Health Agency of Canada for its National Population Health Study of Neurological Disease in Canada, note: “Epidemiological studies investigating the association between prior exposure to lead and ALS began about five decades ago, after a series of ALS cases…
With the second round of open enrollment now underway, the Affordable Care Act is expected to help narrow racial and ethnic disparities in insurance coverage, a new report finds. However, not all communities are predicted to benefit equally. Because nearly half of the country’s legislatures decided against expanding Medicaid eligibility, black Americans may continue to face difficulties finding quality, affordable health coverage. This month, the Urban Institute’s Health Policy Center released a new report detailing racial and ethnic differences in insurance rates under the ACA. Using data…
When compared with gasoline-powered cars, vehicles fueled with electricity from renewable sources could cut air pollution-related deaths by 70 percent, according to a new study, which noted that air pollution is the country’s greatest environmental health threat. Published this week in the Proceedings of the National Academy of Sciences, the study’s researchers examined the impact of various vehicle energy sources on the concentrations of two types of air pollutants known to affect human health: particulate matter and ground-level ozone. Previous research has found that air pollution causes…
Feeling tired? You’re not alone. A new study finds that many U.S. workers aren’t getting enough sleep, which is essential to optimal health, and that people who work multiple jobs are at heightened risk of getting less than the recommended hours of nightly rest. To conduct the study, which was published in the December issue of the Sleep journal, researchers examined the responses of nearly 125,000 Americans ages 15 years old and older and who participated in the American Time Use Survey between 2003 and 2011. They found that work was the dominant reason for reporting less sleep across nearly…
“Too many oil and gas industry workers are being hurt or killed on the job,” said Assistant Secretary of Labor for Occupational Safety and Health, David Michaels in remarks delivered to the more than 2,000 people who gathered last week in Houston for the 2014 OSHA Oil & Gas Safety and Health Conference. As part of efforts to address industry safety issues, the US Occupational Safety and Health Administration (OSHA) has announced a new effort to improve the safety of workers employed in the oil and gas industry. Described as an “alliance,” the initiative involves a two-year agreement…
In ongoing public health efforts to curb the obesity epidemic, better menu and nutrition labeling is often tapped as a low-cost way to help make the healthy choice, the easy choice. And while the evidence on the effectiveness of such interventions is still emerging, a recent study found that educating young people on the calories in sugar-sweetened beverages did make a positive difference. Published in the December issue of the American Journal of Public Health, the study focused on an experiment inside six corner stores located near middle and high schools within low-income, predominantly…
As public health practitioners increasingly look upstream to identify the determinants that put people on a trajectory toward lifelong health and wellbeing, early childhood is often tapped as a pivotal intervention point. Now, a new tool is available that practitioners can use to measure neighborhood-level opportunity indicators that are fundamentally linked to children’s health. In the November issue of Health Affairs, researchers presented the newly developed Child Opportunity Index for the 100 largest U.S. metropolitan areas. The index covers three domains of opportunity: educational,…
Children who have the opportunity to attend full-day preschool programs, versus part-day programs, tend to score higher on school readiness measures such as language, math, socio-emotional development and physical health, according to a recent study. So, why is this finding important to public health? Because education has literally been described as an “elixir” for lifelong health and wellbeing. When it comes to the upstream factors that can put people on a lifelong trajectory toward longer life expectancy, greater health and less chance of disability and disease, educational achievement is…
As paid sick leave policies gain momentum across the country, a new study finds that such policies do indeed improve worker morale and have little overall effect on employer profitability. Published in the December issue of the American Journal of Public Health, the study examined the effects of a 2007 paid sick leave policy in San Francisco, which became the first U.S. jurisdiction to enact a paid sick leave ordinance. (A number of states and cities have followed San Francisco’s lead — most recently Massachusetts, which passed a statewide earned paid sick leave policy by ballot measure…
Decreased lung function, breast cancer, miscarriage, depression and neurological disease. These are just a few of the health and disease risks that salon workers disproportionately face while on the job, according to a new report on the impact of toxic chemicals within the beauty and personal care industry. Yesterday, Women’s Voices for the Earth, a nonprofit working to eliminate toxic chemicals from workplaces, homes and communities, released “Beauty and Its Beast: Unmasking the Impact of Toxic Chemicals on Salon Workers,” which highlights decades of research on beauty care workers and…
In the span of just a couple years, five of Heather Buren’s colleagues at the San Francisco Fire Department were diagnosed with breast cancer. At first, Buren thought the diagnoses were part of the unfortunate toll that comes with age. Still, something felt amiss — “it just felt so disproportionate to me,” she said. Around the same time, Buren helped a good friend and mentor within the department as she underwent a double mastectomy. Buren said it was at that moment that she decided to take decisive action. “(The cancer) just brought her to her knees,” she told me. “Now she’s good and back in…
Researchers with Michigan State University’s (MSU) Department of Occupational and Environmental Medicine have done it again. First it was work-related burns. Then it was work-related amputations. Now it is work-related skull fractures. The MSU researchers continue to poke holes in the federal government’s annual estimates of occupational injuries. Joanna Kica, MPA and Ken Rosenman, MD used data from acute care hospitals, workers’ compensation records, death certificates and police reports to identify work-related fatal and non-fatal skull fractures occurring in Michigan in 2012. They…
A recent study of air quality around unconventional oil and gas extraction sites — more commonly referred to as fracking — found high levels of benzene, hydrogen sulfide and formaldehyde, all of which pose risks to human health. But what makes this study particularly interesting is that the air samples were collected by the very people who live near the extraction sites, and the collection times were specifically triggered by the onset of health symptoms. Published yesterday in the journal Environmental Health, the study involved residents living near 11 unconventional extraction sites in…
Raising the federal minimum wage isn’t only good for workers — it’s good for the federal budget as well, according to a new issue brief from the Economic Policy Institute. Released earlier this month, the policy brief details just how many low-wage workers have to depend on public assistance programs to make ends meet and how increasing the minimum wage could save billions in federal spending — and those billions could be redirected toward creating stronger, more resilient anti-poverty programs. The brief reports that about half of all workers earning less than $10.10 per hour, the new…
Despite substantial public opposition and the “grave concerns” of about 50 members of Congress and significant unanswered questions about human and environmental health impacts, the Environmental Protection Agency (EPA) has approved a new herbicide called Enlist Duo for use on genetically engineered corn and soybeans in Illinois, Indiana, Iowa, Ohio, South Dakota and Wisconsin. EPA, which says it has approved Enlist Duo “to manage the problem of resistant weeds” is now considering approving Enlist Duo for use in ten more states: Arkansas, Kansas, Louisiana, Minnesota, Missouri, Mississippi,…
At this point, it’s pretty clear that soda is bad for your health. But a new study has found that it may be even worse than we thought. Published yesterday in the American Journal of Public Health, the study found that drinking sugar-sweetened beverages may be associated with cell aging. More specifically, researchers studied the effect that soda has on telomeres, which are the protective units of DNA that cap the ends of chromosomes inside human cells. Previously, the length of telomeres within white blood cells has been tied to shorter lifespans as well as the development of chronic…
When it comes to substance abuse disorders, public health and the public at-large are hardly on the same page — in fact, they’re not even reading the same book. And that’s a serious problem for sustaining and strengthening efforts to treat addiction and advancing effective public health policy. “We already know quite a bit about public attitudes toward mental illness and we were interested in learning more — especially in the context of prescription (painkiller) drug abuse — about what the public thinks about issues related to drug addiction,” Colleen Barry, who recently co-authored a study…
"If the California Public Health Department had been able to find out that my company was using a chemical that was killing people, I might never have gotten so sick that I had to have a lung transplant," Ricardo Corona told a California Judiciary Committee last April, testifying in favor of California Senate Bill (SB) 193 that Governor Jerry Brown signed into law on September 29th. The law, which amends California's Hazard Evaluation System and Information Service (HESIS), will become the first in the country to require companies that manufacture and distribute toxic chemicals to provide a…
Worldwide, the numbers of children who die before their fifth birthdays is on the decline. Still, millions of children are being lost to diseases and complications that are completely preventable. In a study published earlier this week in the Lancet, researchers examined the reasons behind the 6.3 million deaths among children younger than 5 in 2013 — a number that’s significantly less than the 9.9 million such deaths that occurred worldwide in 2000. Nearly 2 million of the 2013 child deaths were due to complications from preterm birth and pneumonia, both of which were leading causes in 2000…
Building excitement around school meals with the help of guest chefs and fresh recipes could be a significant boon for school lunch programs as well as student eating habits, a new study found. Recently published in the journal Appetite, the study examined the impact of Chefs Move to Schools, an initiative of First Lady Michelle Obama’s Let’s Move campaign. With an overriding goal of encouraging schoolchildren to make healthier meal choices, Chefs Move to Schools pairs volunteer professional chefs with schools to offer cooking education to kids as well as culinary advice to school food…
