MADISON Sleep apnea repeated pauses in breathing during sleep is much more common than previously thought. The condition increases the risk of high blood pressure,depression, heart disease, cancer and death. Losing weight andexercising can offset it. People who sleep too little or too much,regardless of whether they have sleep apnea, are more likely to beoverweight.
Those and other findings about sleep are common knowledge amongscientists today thanks to Don Chisholm, Mary Ellen Havel-Lang,Paul Minkus and more than 1,540 other participants in the WisconsinSleep Cohort Study. The UW School of Medicine and Public Health study, of state workerswho periodically undergo sleep tests at UW Hospital and provideother information, has continued for 23 years. Its latest splash in the national headlines came last month, with afinding that people with severe sleep apnea are five times morelikely to die from cancer. Inadequate oxygen during sleep mightpromote tumor growth, researchers said.
As the longest-running assessment of sleep of its size in thecountry, the Wisconsin study has reshaped notions about sleep andits effects on overall health, said Michael Twery, director of theNational Center on Sleep Disorders Research. Snoring, which once symbolized peaceful sleep, now is a sign ofpossible breathing troubles, said Twery, whose center is part ofthe National Institutes of Health, which funds the $1.5million-a-year Wisconsin study. Also, Twery said, the study is showing that if you have sleepapnea over a period of time, it erodes your health. Wire Drawing Dies for sleep Chisholm, 75, who retired three years ago as a UW-Madisonelectrician, said he s had seven overnight sleep evaluationsthrough the study. Researchers place sensors on the scalp, chest,hands and legs and near the eyes, nose and mouth.
The devicesmeasure breathing, heart rhythm, movement and stages of sleep. It s kind of disconcerting to have all of these Wire Drawing Dies hooked upto you, said Chisholm, of Madison. But I ve gotten used toit. He s learned, from the reports participants get after eachevaluation, that he s a deep sleeper. Havel-Lang, 59, who retired two years ago as a technology managerat the state health department, said she signed up for the study inthe late 1980s largely because of the money participants receive.
They currently get $150 for an overnight sleep evaluation, $100 fordaytime tests of overall health and $35 to fill out questionnaires. I was raising two kids by myself and figured I could use a littleextra money, said Havel-Lang, of Sun Prairie. She has learned she kicks her legs in her sleep. My husbandhasn t complained about it; I must have never kicked him, shesaid.
Whatever their motivation, the participants have made greatcontributions to sleep science, said Terry Young, lead researcherof the study until last year. We could never have had the confidence in our findings and theability to draw our conclusions without the dedication of thevolunteers, Young said. Apnea not that rare The study s first major discovery, in 1993, put Wisconsin on thesleep science map. Sleep apnea was thought to occur in less than 1 percent of adults,but no significant assessments had been done.
The development ofthe first non-surgical treatment for the condition continuouspositive air pressure devices, face masks known as CPAP madedoctors want a better sense of its prevalence. The Wisconsin study found sleep apnea in 9 percent of men and 4percent of women. That was the landmark that put sleep apnea in the attention ofproviders, the government and the public, Young said. An estimated 13 percent of men and 6 percent of women have sleepapnea today, largely because of the obesity epidemic, said PaulPeppard, the study s current leader.
Study participants get overnight sleep evaluations at the hospitalevery four years. For a while, some came back for daytime napstudies. Many women underwent sleep studies at home every six months for 10years to assess the effects of menopause on sleep. Since 2003, mostsubjects have had tests to measure balance, cardiovascular healthand cognitive ability.
With the participants now ages 55 to 85, researchers are exploringthe impact of sleep on memory and shifts in sleep patterns afterretirement. The group s younger years revealed a fact many parents can relateto: A parent loses an average of more than 600 hours of sleep perchild over the course of a child s life, much of it in thepre-school years. Minkus, 66, of Madison, who retired as a financial policy advisersix years ago, said he s enjoyed contributing to sleep science. His evaluations have revealed no sleep apnea or other problems.
Butthey haven t settled a dispute with his wife. I m not sure if I snore, he said. My wife says I do, but Ideny it.
