Lack of sleep as a child could lead to disorders cognitive behavioural- especially in school, a new study has revealed. Scientists say that children between the ages of three and seven that not getting enough sleep are more likely to have problems of attention, emotional controland relations between equals in Middle childhood. Previous researchhas found that there has been a steady decline in the average hoursof sleep in children - aged between 30 to 60 minutes in the past 20 years. However, according to the researchers, parents can detect theseissues from six months and put an end to the problems until it is toolate. The study, conducted by the Massachusetts General Hospital, analyzed data from project Viva, a long-term investigation of the healthimpacts of various factors during pregnancy and after birth. During in-person interviews, the mothers answered questions about their children at six months of age, three years and seven years of age, and annual questionnaires completed when the children were between oneand six years. In addition, mothers and teachers sent instruments survey to assess skills and behavioral problems - including emotional symptoms and problems with behavior or equal relationships when thekids were around seven years of each child. The researchers determined the recommended amount of sleep by age:
12 hours or more at the ages of six months to two years
11 hours or more at the ages of three to four
10 hours or more at ages five to seven
They found that children who live in households with lower income and whose mothers had lower levels of education were more likely tosleep less than nine hours of five to seven years of age. The team also found inadequate sleep is associated with factors as more television show, have a higher body mass index and being African American.
Black children were twice more likely to sleep less than nine hours aday between the ages of five and seven compared to white children.
LACK OF SLEEP WE COST ECONOMY $411 BILLION, SAYS STUDY
Lack of sleep among the working population of the United States is costing the economy up to $411 billion a year, warns a new report.
The researchers consulted national reports and data from the revisedsleep from five different countries to predict the economic effects of insomnia.
United States lose some 1.2 million working days a year for exhaustion - of workers taking off days or not working in your prime.
The study, conducted by the nonprofit RAND Corporation research firm, also warns that lack of sleep dramatically increases risk of mortality.
Lack of sleep was defined as less than six hours per night, while the optimum amount is somewhere
between seven and nine hours.
Those who do not reach the mark of six hours have one higher risk of mortality than 13 per cent of
people who sleep eight hours, researchers found.
Among them - about six and a half hours sleep - also suffer; they have one higher risk of mortality rate of 7% as their better rested peers.
Reports of mothers and teachers found an association between poorfunction and do not receive enough sleep, with teachers report evenbigger problems. Teachers said neurobehavioral in the form of lack of attention and hyperactivity, emotional symptoms such as anxiety and depression, problems between peers and problem behaviors such as aggression and rule - breaking. We found that children receiving an insufficient amount of sleep in their preschool and early school years have a higher risk of neurobehavioral function poor at about age seven, said lead author Dr. Elsie Taveras, Chief of general Pediatrics atthe MassGeneral Hospital for children. ' associations between inadequate sleep and worse performance persisted even after adjusting for several factors that could influence the relationship.' though no linkwas observed between insufficient sleep during childhood - the ageof six months to two years - researchers found that levels of dream at this stage often predict levels in later ages.
A study in February, carried out jointly by the University of Pennsylvania and the University of York in the United Kingdom, found that teens who don't sleep are nearly five times more likely to commit crimesas adults. Scientists said young people which one same-report feeling of sleep mid-afternoon tend to show a more antisocial behavior such as lie, cheat, steal and fight. Dr. Taveras added that health complications could arise as lack of sleep leads to obesity. She said: ' the results of this study
