Nearly one in eleven (8.6%) preschool children in the U.S. has been diagnosed with asthma and in some inner city neighborhoods, the figure is closer to one in seven. But, few asthma management programs are designed for parents of preschool children. The Asthma Basics for Children (ABC) program, established by Columbia University's Mailman School of Public Health and a coalition of community service organizations, educators, parenting programs, and community pediatric providers, addressed this...

Effects on IQ appear to be similar to lead exposure When the EPA phased out the widespread residential use of chlorpyrifos and other organophosphorus (OP) insecticides in 2000-2001 because of risks to child neurodevelopment, these compounds were largely replaced with pyrethroid insecticides. But the safety of these replacement insecticides remained unclear, as they had never been evaluated for long-term neurotoxic effects after low-level exposure. In the first study to examine the effects of...

New study is the first randomized, controlled trial to show that early educational enrichment can bring improved health and healthier behaviors in early adulthood Intensive early education programs for low-income children have been shown to yield numerous educational benefits, but few studies have looked more broadly at their impact on health and health behaviors. A new study conducted by researchers at Columbia University's Mailman School of Public Health examines this issue, using data from...

Despite the existence of effective programs for treating alcohol dependencies and disorders, less than a quarter of people who are diagnosed actually seek treatment. In a recent study by Columbia University's Mailman School of Public Health researchers report that people diagnosed with alcoholism at some point in their lifetime were more than 60% less likely to seek treatment if they believed they would be stigmatized once their status is known. This is the first study to address the underuse...

12 percent of workers would choose to quit or retire rather than report for work Although first responders willingly put themselves in harm's way during disasters, new research indicates that they may not be as willing"” if the disaster is a potentially lethal pandemic. In a recent study, researchers at Columbia University's Mailman School of Public Health found that more than 50% of the first responders and other essential workers they surveyed might be absent from work during a...

Bodegas near the schoolyard are likely sources of junk food for kids at risk for obesity Most studies of the food choices available near public schools have focused on fast food outlets rather than the full range of options available to schoolchildren. A new study by researchers at Columbia University's Mailman School of Public Health examined the patterns of exposure to a broad range of food outlets for school children in New York City. The study, "Disparities in the Food Environments of New...

60 percent of children -- as many as 20,000 -- displaced by Katrina either have serious emotional disorders, behavioral issues and/or are experiencing significant housing instability Five years ago Hurricane Katrina and the flooding of New Orleans caused the evacuation of 1.5 million Gulf Coast residents. After a year, 500,000 people remained displaced, many residing in highly transitional shelters, including the notorious FEMA trailer parks. Now at the five-year mark, substantial...

Effective brain function depends on the efficient signaling from one neuron to the next, a lightning-fast process that depends on a quick release of neurotransmitters at synapses. Exposure to lead during early childhood and even later in life has long been known to affect the release of these critical neurotransmitters. However, the precise mechanism by which lead ions (Pb2+) impair this process has remained unknown. A new study led by Tomás Guilarte, PhD, chair of Environmental Health...

A study by researchers at Columbia University's Mailman School of Public Health suggests that traumatic experiences "biologically embed" themselves in select genes, altering their functions and leading to the development of post-traumatic stress disorder (PTSD). "Our findings suggest a new biological model of PTSD in which alteration of genes, induced by a traumatic event, changes a person's stress response and leads to the disorder," said Sandro Galea, MD, professor and chair of the...

First study to demonstrate association between asthma and acetaminophen is linked to gene involved in detoxification of foreign substances Children who were exposed to acetaminophen prenatally were more likely to have asthma symptoms at age five in a study of 300 African-American and Dominican Republic children living in New York City. Building on prior research showing an association between both prenatal and postnatal acetaminophen and asthma, this is the first study to demonstrate a direct...
