CDC study examines sleep patterns of Americans in four states

BY Michael Johnsen

ATLANTA About 10 percent of adults reported not getting enough rest or sleep every day in the past month, according to a new four-state study released by the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report released Thursday.

The data from the four states—Delaware, Hawaii, New York and Rhode Island—may not reflect national trends. But an additional study conducted by CDC utilizing data from the National Health Interview Study indicated that across all age groups the percentage of adults who, on average, report sleeping six hours or less has increased from 1985 to 2006.

Nationwide, an estimated 50 to 70 million people suffer from chronic sleep loss and sleep disorders. Sleep loss is associated with health problems, including obesity, depression, and certain risk behaviors, including cigarette smoking, physical inactivity and heavy drinking, the CDC reported.

“It’s important to better understand how sleep impacts people’s overall health and the need to take steps to improve the sufficiency of their sleep,” stated Lela McKnight-Eily, the study’s lead author and a behavioral scientist in CDC’s Division of Adult and Community Health. “There are very few studies to assess and address sleep insufficiencies; therefore, more needs to done to better understand the problem and to develop effective sleep interventions.”

The study, “Perceived Insufficient Rest or Sleep–Four States, 2006,” analyzed data from CDC’s Behavioral Risk Factor Surveillance System survey. Among the four states, the percentage of adults who reported not getting enough rest or sleep every day in the past 30 days ranged from 14 percent in Delaware to 8 percent in Hawaii.

The study also found that the prevalence of insufficient sleep decreased with age. An estimated 13.3 percent of adults aged 18-34 reported insufficient rest or sleep everyday in the past month compared to only 7.3 percent of adults ages 55 and older. While some studies have found sleep disturbance more prevalent among older adults, results from this study are consistent with other research that supports the idea that older adults (who are more likely to be retired) make fewer complaints regarding impaired sleep and adapt their perception of what encompasses sufficient sleep.

In addition, the study showed that only one out of three (29.6 percent) adults said they did get enough rest or sleep every day in the past month.

The study comes just before the National Sleep Awareness Week, March 3-9, an annual campaign held in conjunction with Daylight Savings Time.

NanoMask final test shows better than 99 percent effectiveness

BY Michael Johnsen

LAS VEGAS Emergency Filtration Products on Wednesday announced the results of the final report for the assessment of virucidal effectiveness of treated masks (the NanoMask filter media) using avian influenza virus from the independent testing laboratory which conducted the test.

According to the final report, the test resulted in a 99.96 percent reduction of the avian influenza virus.

The final report was based on filter media samples coated with a silver nanoparticle formulation which underwent one year of simulated aging. The sample was challenged with the avian influenza strain H9N2.

This result compares favorably with a previously disclosed result which indicated a 99.75 percent reduction obtained from a preliminary report by the same independent testing laboratory.

EFP plans to complete a series of tests necessary to the information required to support its 510(k) submission to the FDA for the NanoMask, the company announced in November, including tests of accelerated aging, with follow-on efficacy testing, which ascertains the product’s ability to kill pathogens after a prolonged period of time. This will help determine the NanoMask’s accurate shelf life for inventory purposes.

Other testing expected to be completed prior to completion of the accelerated aging test are leaching tests, which ensure that the silver nanoparticle formulation does not separate from the filter media.

Sales of the NanoMask have been held pending FDA approval, at least according to the handful of web sites advertising the NanoMask. The mask, however, appears to have been designed for the consumer market—there are presently five adult masks (yellow, green, red, blue and purple) and three child masks (yellow, green and purple), all advertised for $12.99 on birdfluprotection.com. Similarly, a 10-pack of replacement filters also retails for $12.99 on the site.
