How your kid behaves could have something to do with how well he or she sleeps (and breathes!) at night, according to a new study.


Research published in the journal SLEEP shows an association between obstructive sleep apnea -- where a person stops breathing for periods of time during sleep, leading to disrupted sleep -- and behavioral and learning problems in kids.


Scientists from the University of Arizona analyzed sleep disorder status and behavior of 263 kids ages 6 to 11 who were part of the Tucson Children's Assessment of Sleep Apnea Study. Among those kids, 23 had an incident of sleep apnea that occurred during the study, while 21 had persistent sleep apnea. And after following up with the kids five years later, 41 who had presented with sleep apnea during the study no longer had breathing problems while they were sleeping.


Researchers found an association between kids having sleep apnea and also having behavior problems.


Specifically, those who had an incident of sleep apnea had a four to five times higher risk of also having behavior problems. And those with persistent sleep apnea had a six times higher risk of also having behavior problems, and a seven times higher risk of having learning problems (as reported by their parents) and three times higher risk of having poor grades in school (C or lower).


The results fall in line with past findings on sleep apnea and behavior problems in kids. A study published last year in the journal Pediatrics showed that kids with sleep breathing problems had a 40 percent higher risk of behavior problems by the time they reached age 7, compared with those without such problems, MyHealthNewsDaily reported.


What's more, a Pediatrics study also published last year showed an association between sleep problems in kids and likelihood of requiring special education.


According to the American Sleep Apnea Association, sleep-walking, growth issues and metabolic problems can also arise from sleep apnea in kids, not to mention a higher risk of obesity.

  • Sleep Apnea Increases Risk Of Heart Attack


    The sleep disorder has a number of poor effects on the heart. "It's as if somebody's choking you, so your heart rate goes up, your blood pressure goes up," Charles Czeisler, M.D., the Baldino Professor of Sleep Medicine at Harvard Medical School told <em>Health</em> magazine. "Over time, even your daytime blood pressure is higher." Sleep apnea may be responsible for a third of all cases of <a href="http://www.huffingtonpost.com/2012/03/14/sleep-health_n_1310353.html">high blood pressure</a> in Americans, he told the magazine. A 2007 study showed just how serious these cardiovascular effects of sleep apnea are. The research found that people with sleep apnea were <a href="http://www.sciencedaily.com/releases/2007/05/070520183533.htm">30 percent more likely to have a heart attack</a> or die of any cause over a four to five year period.




  • Sleep Apnea May Increase Depression Risk


    The under diagnosed sleep condition takes a <a href="http://www.huffingtonpost.com/2012/03/30/sleep-apnea-depression-risk_n_1391707.html">serious toll on the mood</a>, according to March research from the CDC. In fact, men with sleep apnea were more than twice as likely and women more than five times as likely to feel hopeless, lose interest in their regular activites and display other signs of clinical depression, Health.com reported. Snoring did not seem to be associated with depression. Luckily, the very same <a href="http://www.huffingtonpost.com/2012/06/15/sleep-apnea-treatment-depression-cpap_n_1597703.html">treatment for sleep apnea may also ease depression</a>, according to Cleveland Clinic research.




  • Sleep Apnea May Be A Risk Factor For Diabetes


    There is a growing body of research supporting a link between the presence of sleep apnea and <a href="http://www.huffingtonpost.com/2012/05/24/sleep-apnea-diabetes-type-2-_n_1539933.html">metabolic disorders like diabetes</a>, HuffPost reported in May. Both moderate and severe obstructive sleep apnea were found to be predictors of the disease. A previous study found that people with sleep apnea had more than <a href="http://news.yale.edu/2007/05/24/sleep-apnea-increases-risk-heart-attack-and-diabetes">double the risk of developing diabetes</a>.




  • Sleep Apnea May Increase Cancer Risk


    Not only do people with sleep apnea have a <a href="http://well.blogs.nytimes.com/2012/05/20/sleep-apnea-tied-to-increased-cancer-risk/">higher risk of developing cancer</a>, but they also have a higher risk of dying from the disease, the <em>New York Times</em> reported. Two studies in May examined this link. One found people with sleep apnea had a 65 percent higher change of developing any kind of cancer. The second found that disordered breathing contributed to a five-times higher rate of dying from the disease.




  • Sleep Apnea May Sap Your Libido


    Excessive sleepiness is certainly enough to kill the mood, but research suggests that sleep apnea in particular has an effect on sexual function in both men and women. It may <a href="http://well.blogs.nytimes.com/2011/10/10/really-the-claim-sleep-apnea-causes-sexual-problems/">drive down sex hormones</a> like testosterone in a way that can extinguish the flame for women and cause erectile dysfunction in men, according to the <em>New York Times</em>. And while the typical treatment -- a CPAP machine -- is not exactly an aphrodisiac, Dr. Michael J. Breus writes, it can help not only with sleep apnea, but <a href="http://www.huffingtonpost.com/dr-michael-j-breus/sleep-apnea_b_1661687.html">with the sexual side effects as well</a>.




  • Sleep Apnea May Increase Stroke Risk


    Researchers have long studied the link between the sleep disorder and the risk of stroke, but a small recent study found that 51 of 56 stroke patients evaluated -- or <a href="http://www.huffingtonpost.com/dr-michael-j-breus/sleep-apnea_b_1342311.html">91 percent of patients</a> -- had sleep apnea, Dr. Michael J. Breus wrote for HuffPost. More research is still needed to determine just what role disrupted breathing plays in this elevated risk.




  • Sleep Apnea Increases Accident Risk


    It's not rocket science -- excessive sleepiness during the day leads to sleepier drivers who are at a higher risk of crashing. But a 2008 study found that people with sleep apnea have double the risk of being in a car accident and are <a href="http://www.sciencedaily.com/releases/2008/02/080218214401.htm">three to five times more likely to be in a serious crash</a>. The study was the first to examine the severity of car crashes among people with sleep apnea, and found that even mild disordered breathing was linked to increased risk.




  • Sleep Apnea Is Linked To Pregnancy Complications


    Granted, Perry doesn't have to worry about this particular concern. While sleep apnea is often perceived as a problem predominately for men, <a href="http://www.huffingtonpost.com/2012/08/16/sleep-apnea-in-women-may-_n_1779127.html">women are not immune</a>. And, in fact, sleep apnea presents unique complications for women. A recent study found that women with sleep apnea were more likely to develop high blood pressure during their pregnancies, to require a C-section birth and their babies were more <a href="http://www.huffingtonpost.com/2012/09/21/sleep-apnea-in-pregnancy-_n_1903534.html">likely to be admitted to the neonatal intensive care unit</a>.
